Editor’s Viewpoint

Would MPs pass the ‘competence’ test? There’s an interesting concept gaining greater prominence in the electrical industry at the moment. It’s called competence. You may even have heard of it :) Its principle is grounded in the fact that, just because someone can call themselves an electrician, or has a particular qualification, it doesn’t automatically mean they’re competent to carry out every conceivable type of electrical work. As the industry embraces specialist technologies such as solar PV, battery storage and EV charging, greater emphasis is being placed on proving that the individual carrying out the work has the knowledge, skills and experience required for that specific task. Radical stuff, isn’t it? Apparently, if you’re going to make important decisions, take responsibility for something and potentially affect the safety of others, you should be able to demonstrate some idea of what you’re doing. Which got me thinking: perhaps someone should send a copy of the new competence requirements to Westminster. Because while electrical businesses are increasingly expected to prove that the right person is doing the right job, government appears to operate a slightly different system. There, you can seemingly be handed responsibility for an entire department on Monday, spend Tuesday learning where the toilets are and, by Friday, be reshuffled into another role covering a subject about which you know equally little. Today, you’re overseeing transport. Tomorrow, energy. Next week? Who knows. Health? Education? Defence? Stick your hand in the tombola and see what comes out. No competence matrix, practical assessments or CPD records required. Just a new office, another red box and a team of civil servants quietly explaining how everything works. Imagine applying the same approach in the electrical industry: “Morning, Dave. I know you’ve spent 20 years doing domestic rewires, but we’ve decided you’re designing a large-scale battery storage system today. Here’s the manual. Best of luck.”

You, your customers and the industry as a whole just wouldn’t accept it. And, increasingly, the regulatory framework won’t either. Yet when it comes to running the country, we seem remarkably comfortable with the idea that changing someone’s job title automatically downloads all the necessary knowledge into their brain overnight. Perhaps Whitehall could borrow a few ideas from the electrical sector. Before taking responsibility for a department, ministers could demonstrate relevant knowledge, skills and experience. Where gaps exist, training could be provided. Those new to the role could operate under suitable supervision and their competence could be periodically reviewed. We could even introduce a Ministerial Competence Scheme, though, admittedly, getting enough people through the initial assessment could delay implementation. Of course, working in government isn’t the same as skilled electrical work. Ministers are there to make political decisions, supported by civil servants and specialist advisers. Nobody expects the Transport Secretary to service a train or the Energy Secretary to wire an inverter. But the underlying principle still applies. Responsibility should be matched by capability, and the greater the consequences of your decisions, the stronger the argument that you should understand the subject. That’s why the electrical industry’s increased focus on individual competence should be welcomed. Yes, it will bring additional responsibilities and, inevitably, paperwork. But the principle is difficult to argue against. Being an electrician shouldn’t mean being considered competent to do everything electrical simply because of the title on your business card. Perhaps those running the country could learn something from that. Have a good month and enjoy the issue.

NICEIC unveils remote EV charging course NICEIC has launched a new tutor-led remote training course designed to help electrical contractors gain a recognised electric vehicle charging point (EVCP) qualification without the need to attend a training centre. The one-day Level 3 Award in the Requirements for the Design and Installation of Domestic and Small Commercial Electric Vehicle Charging Installations (2921-34) is accredited by City & Guilds and remotely invigilated. Sessions are delivered in real time by experienced tutors, allowing learners to ask questions and receive immediate feedback

while developing their knowledge and competence in EV charge point installation. Alex Robinson, Head of Training at NICEIC, said: “With consumer demand for electric vehicles continuing to grow, we’re seeing real-world electrification become a defining theme for the year ahead. “In 2025 alone, EV sales rose by 28%, with around one in three new cars sold now fully electric. That pace of change means we need more contractors competent in the technology to meet demand and enable the roll-out. “Our focus is to make high-quality training more accessible to electrical

contractors across the UK. This course allows us to reach those who may not be able to travel to a training centre, while still delivering the tutor-led experience that supports real understanding and competence.” GET MORE INFORMATION OR SECURE A PLACE ON A FUTURE COURSE AT: WWW.RDR.LINK/ECB001

New guidance published on competence requirements The Building Safety Regulator and the Ministry of Housing, Communities and Local Government have published new guidance setting out the Mandatory Technical Competence (MTCs) requirements for self-certification schemes. The new framework helps scheme operators assess whether installers have the right skills, knowledge, experience and behaviours to carry out and certify

work safely and competently. The MTCs aim to create a more consistent approach to competence across the sector, while keeping pace with changes in regulation, standards, industry practice and technology. The framework covers several areas of work, including electrical, air conditioning, plumbing and heating, insulation, roofing, fenestration, gas, liquid fuel, and solid fuel and biomass.

It’s a useful read for anyone involved in competent person or self-certification schemes, particularly as expectations around competence continue to develop. Check out the article on pages 29 and 30 to find out more about what it means for you and your business.

ESR releases EICR Fact Sheet for tenants The Electrical Safety Roundtable (ESR) has launched a new EICR Fact Sheet designed to help tenants better understand electrical safety checks carried out in their homes. While an EICR provides important information about the condition of an electrical installation and any investigative or remedial work required, the technical nature of the document can make its findings difficult for tenants to interpret. To help improve understanding, the ESR’s Electrical Safety in Social Housing

The resource explains what an EICR is and the difference between satisfactory and unsatisfactory outcomes. It also provides information on C1, C2, C3 and FI classification codes, alongside examples of observations tenants may encounter within a report.

Sub-Group has developed a fact sheet that landlords can provide to tenants alongside their EICR, giving them a better understanding of the inspection’s findings.

COVER STORY Steve Kaye, Sales & Marketing Manager at Forum Lighting Solutions, introduces the company’s new iconic BHS decorative lighting brand.

MAKE YOURSELF AT HOME

t Forum Lighting Solutions, we’re rolling out an extensive new catalogue of BHS decorative lighting to the wholesale electrical market, marking a signiﬁcant expansion of our offering and bringing high-quality interior design directly to trade counters, and electrical professionals, nationwide. Through this major new range of decorative lighting products, launched under the prestigious and instantly recognisable BHS name, we’re giving electrical installers the opportunity to capture a larger share of the lucrative decorative lighting market while providing their customers with access to a trusted household brand. Celebrating a century of British design legacy By introducing the BHS label to our portfolio, we’re bringing almost a century of retail heritage directly to the electrical trade channel. Founded in London in 1928, British Home Stores was built on a simple purpose: to offer well-designed, affordable products for everyday living. Throughout the 20th century, BHS grew into one of the UK’s most trusted high-street

department store brands. Celebrated for making good design accessible, its homeware and lighting ranges became ﬁxtures in generations of British households, earning an enduring reputation for reliability and timeless appeal. While the physical high-street stores closed their doors in 2016, marking the end of a retail era, the emotional connection customers had with the brand remained incredibly strong. Today, British Home Stores lives on as a heritage-led homeware and lighting brand, rooted in its long-standing values of quality, timeless design and attainable style. Through our partnership with BHS, we’re building on that legacy and

PROFESSIONAL ELECTRICIAN

Six distinct styles for modern living We’ve carefully curated the new BHS range into six distinct style families, each designed to cater to evolving consumer tastes. For high-impact glamour, All That Glitters features dramatic crystal elements, polished chrome and statement chandeliers. The Showhome collection, meanwhile, delivers a polished, aspirational look through oversized glass pendants, sleek velvet textures and neutral palettes. For those seeking a more nostalgic interior, Mid Century channels the sophistication of the 1950s and ’60s through clean geometric lines, warm brass tones and iconic orb styling. For minimalist functionality, Scandi combines pale woods, matt finishes and soft monochromatic tones to create calm, light-filled spaces. Our Heritage collection introduces vintage British elegance through timeless antique brass finishes, sophisticated ribbed glasswork and classic silhouettes that bring period character to traditional homes. Finally, Country captures modern farmhouse charm and rustic tranquillity by

020_PE_SEPT26_Layout 1 30/07/2026 15:39 Page 21

layering natural materials such as woven rattan, exposed wood and cracked ceramic textures to create a warm, wholesome and beautifully lived-in feel. By offering such a diverse selection of styles, we’ve made it easier for contractors and homeowners to ﬁnd the perfect decorative lighting solution for almost any interior project. Unrivalled trade support and availability We understand that, in the fast-paced electrical trade, product availability is everything. That’s why we’re backing this major launch with the logistical support our customers expect from Forum, helping wholesalers and contractors avoid the long factory lead times often associated with high-end decorative lighting. We’re fully stocking every item in the new BHS decorative range at our central distribution hub, with orders available for immediate dispatch and guaranteed next-day delivery. This means trade professionals can keep their projects moving forward without unnecessary and costly delays. To support the launch, we’ve also produced a comprehensive, beautifully designed 96-page dedicated catalogue.

Far from being a standard technical manual, it’s packed with inspirational lifestyle imagery and has been created as a powerful counter-top selling tool. Installers can use the catalogue when sitting down with homeowners, helping customers to visualise exactly how individual fittings could look in-situ and making the product selection process easier. The complete BHS decorative lighting range, alongside our wider portfolio, can also be viewed through our website, where customers can place orders directly via our dedicated online portal. A complete, one-stop lighting portfolio While we’re incredibly excited about the launch of the BHS decorative range, it doesn’t replace our core identity. Instead, it complements the established and trusted product families that have made Forum a staple brand on wholesale shelves for many years. Trade professionals can continue to rely on Kinetic for wireless, battery-free switching solutions that can help revolutionise installation times, while Zink Outdoor provides sleek, architectural garden lighting designed to withstand the elements. For more specialised environments, our Spa Bathroom range provides IP-rated, safety-compliant fittings engineered for damp environments without compromising on style.

THE TRAINING GROUND I don’t have a Level 2 electrical qualification but I have over 10 years’ experience in the trade. Can I do the Experienced Worker Assessment? Potentially yes, if you can pass what is known as the EWA Entry Test. If you have developed extensive knowledge on-site over the years, but don’t meet the EWA entry criteria of holding a Level 2 theory qualification, the EWA Entry Test is now available for those with substantial practical experience and technical understanding to demonstrate their proficiency to the required standard before embarking on the EWA. Before you start, you must ensure you’re suitable for the Experienced Worker Assessment – don’t risk wasting your money by not completing it. This means reviewing the EWA ‘Skills Scan’ to confirm you: ● Currently carry out the full scope of work required, ● Have sufficient practical experience, ● Can generate the workplace evidence required

within the 18-month assessment period. If you believe you’re eligible but don’t hold a Level 2 theory qualification listed in the Skills Scan, providing you have significant work experience, typically 10 years or more, you can consider taking the EWA Entry Test. We recommend reading the test coverage information on the EWA website to confirm you understand the underpinning knowledge of electrical science and principles expected at this level. It’s a Level 3 test with 50 questions covering electrical practices, theory, design principles and the wider technical understanding expected of a qualified electrician. Tests are delivered during scheduled assessment windows throughout the year, and you’ll need to attend a training centre in person to sit the test. If you pass the Entry Test, you must enrol onto the relevant Experienced Worker Assessment within six months. VISIT THE EWA WEBSITE FOR MORE INFORMATION AND SUPPORT AT: WWW.RDR.LINK/ECB012

Q. I’m working on sites where bollards keep getting knocked, bent or vandalised, and clients are fed up with constant replacements. Is there an exterior bollard on the market that can handle impact, reduce maintenance callouts, and still offer flexible lighting options? When you’re upgrading outdoor lighting on commercial or residential sites, durability isn’t just a nice to have – it’s the difference between a fitting that lasts and one that becomes a maintenance headache. Ovia’s Beelo Bollard has been engineered specifically with that installer reality in mind, and its standout feature is the optional impact absorbing base. This accessory is a genuine problem-solver on sites where bollards are vulnerable to knocks, scrapes or outright vandalism. The base incorporates a built in spring mechanism that allows 360° impact absorption and enables the bollard to tilt up to 30° upon impact and then return to its original upright position. That translates to fewer call-outs and replacements for installers, and a lighting scheme that stays intact, even in high traffic or high risk areas such as car parks, retail environments and office complexes. The Beelo Bollard’s modular design also makes life easier on-site. Each head – Flat, Domed, Cone or Louvered – is prewired with a Unicrimp Q Nect IP68 connector and supplied with cable and lever connectors for quick, safe, waterproof connection. Swapping a head takes seconds: three screws out, align, reattach. Performance-wise, Beelo delivers serious output: up to 3600 Lm, 144 Lm/W efficacy, CCT switchability (3000K/4000K/6000K) and power switchability (14 W/19 W/24 W), all in an IP65, IK08 housing built for real world conditions.

COMMENT

“A RUSHED ROLLOUT COULD WEAKEN CONFIDENCE” hilst we support wider access to cheap and clean energy, plug-in solar PV units should only enter the mass market once the necessary regulatory, technical and product safety framework is fully in place. Without that foundation, there’s a serious risk of avoidable hazards in homes, uncertainty for the electricity system, and lasting damage to public conﬁdence in the energy transition. As organisations representing electrical safety, engineering standards and technical competence across the electrotechnical sector, we believe there are serious issues that must be addressed before any mass-market adoption. We’re urging government to proceed with caution and ensure that safety, product assurance, competence and system resilience are designed into any rollout from the outset.

Public safety shouldn’t be a secondary consideration It remains unclear how plug-in solar panels will interact with the millions of existing electrical installations in UK homes, particularly in older properties where this wiring may have deteriorated, the operation of uni-directional RCDs (residual current device) and RCBOs (residual current circuit breaker with overcurrent protection) may be affected, and maintenance may have been inconsistent. A product marketed as simple and consumer-friendly could in practice be connected to electrical installations that were never assessed for this type of product. In such cases, there could be an increased risk of ﬁre and danger to life due to the inability of the circuit to deal with the importation of power.

As the potential adoption of plug-in solar PV units continues to create debate, a group of leading industry authorities – consisting of ECA, ESF, IET, NICEIC and SELECT – explain why public safety must be the first principle in any national rollout.

There are six public safety issues:

flow – Generating 1 Bi-directional and consuming electricity isn’t the same Plug-in solar PV units operate differently to the conventional appliance plugged into an electrical installation. Rather than just supplying power to an appliance, with plug-in PV units, the installation now has to import power, meaning that power ﬂow is in both directions. This introduces technical issues that leave most homeowners unaware of the dangers. With electrical sources being applied to

what we often refer to as the ‘load side’ of protective devices, Amendment 3:2024 to BS 7671:2024 addressed this very issue. Under certain conditions, the RCD, a key protective device in the home’s consumer unit, can be compromised. It may be possible to reset but the protective device may not operate as normal. This could be dangerous as the assumed protection will not be active. One death resulting from this lethal failure has already been reported by one Australian state, however it should be noted that this view isn’t shared by regulators from other Australian states.

COMMENT

risk 2 Fire Over 50% of UK housing stock is more than a century old. These properties may have old, damaged or deteriorating electrical wiring, unﬁt to carry extra load. Without a proper electrical assessment, it’s unwise to add a plug-in solar PV unit and is indeed contrary to existing British Standards, i.e. clause 5 of BS 1363-1. Plug-in solar PV units, especially multiple units, can increase the risk of localised overheating of cables.

and dangerous 3 Inconsistent product standards The government has announced that plug-in solar panels will be made available quickly, but if products reach the retail market before a robust and enforceable UK standard is fully embedded, consumers may be exposed to inconsistent quality, unclear compliance requirements and unsafe imports. For example, some products are already being promoted with ﬂattened cables intended to pass under doors or through openings not designed for electrical equipment. Without clear standards, testing and enforcement, such accessories could normalise unsafe practice in domestic settings and increase the risk of insulation damage and overheating, raising the potential for ﬁre.

without a clear notification and oversight regime, visibility of what’s connected to the system will be reduced at the very point when visibility matters most. The electrical industry recommends that clear guidance is given to consumers to notify the DNO, before a device becomes operational. The risk isn’t theoretical. If multiple flats in a single block were each to install plug-in solar PV units, the cumulative effect on the local network could be significant. We should be wary of treating these systems as negligible simply because each individual unit is small. At scale, small installations can produce material consequences for network planning, safety and resilience.

and insurance questions 5 Liability remain unresolved There are also serious unanswered questions about insurance and liability. If a ﬁre or electrical fault is linked to a plug-in solar PV unit, it’s not yet clear how insurers will assess cover where the product was self-installed, not declared in advance or connected to an unsuitable electrical installation. Consumers shouldn’t be encouraged to adopt these products before they fully understand the consequences, potentially leaving landlords, leaseholders and insurers to manage the fallout.

capacity is vital to network 6 Daisy-chaining 4 Grid Consumers, seeking convenience, resilience One of the central safeguards in the UK electricity system is that new electricity generating technologies are introduced in a way that network operators can monitor and manage. Industry advice has long been that new installations such as solar PV units and EV chargepoints should be notiﬁed to the local Distribution Network Operator (DNO) because cumulative demand and generation affect local network capacity and stability. If plug-in solar PV units are normalised as an off-the-shelf consumer purchase

may use extension leads, adaptors or multiple devices on the same circuit. Improvised installations significantly increase the likelihood of overheating and fire, as well as creating trip and fall hazards from trailing cables poor installations/fixings into gardens or on balconies with a risk of becoming loose or falling from height, with disastrous consequences. A particular concern if used in a high-rise building. Additionally, rooftop solar PV has a single dedicated connection to the

PROFESSIONAL ELECTRICIAN

electrical installation through an inverter. An inverter converts the direct current (DC) generated by the solar panels to alternating current (AC) which is the type of electricity that’s conventionally used to power homes and feed into the National Grid. When a power cut in the street occurs, the inverter will shut down very quickly to halt the export of power. Where multiple plug-in solar PV units are plugged in to the electrical installation through socket outlets, each has an individual connection to the installation, and it isn’t known how quickly multiple plug-in solar PV units will shut down in the event of a power cut. A low upfront cost must not ultimately override safety The appeal of plug-in solar PV units is obvious: low-cost, visible and quick to deploy. But affordability alone isn’t a sound basis where electrical safety is concerned. If cost becomes the dominant driver, there’s a danger that quality assurance, competent installation, enforcement and consumer protection will be treated as optional rather than essential. A poorly regulated bargain product may reduce bills in the short-term, but it can also transfer risk onto households, emergency services, insurers, network operators and, ultimately, government. A rushed rollout could potentially weaken conﬁdence in the energy transition. The electrotechnical industry advocates innovation and recognises the potential role that new technologies can play in expanding access to cleaner energy. But plug-in solar PV units shouldn’t be rolled out unless, and until, the supporting framework is in place: clear product standards, robust enforcement, competent installation pathways, appropriate consumer guidance, and a mechanism to protect both householders and the electricity distribution network. Due diligence isn’t a barrier to progress. It’s what makes progress safe, credible and sustainable.

SPECIAL REPORT With individual competence under increasing scrutiny, Michael Collinge MIET, Technical Director at Flexi-Orb, delves into what the latest regulatory requirements mean for electrical businesses and their workforce.

MAKING COMPETENCE YOUR BUSINESS

’d like to start this article by stating, for transparency purposes, that these observations reflect my personal views, informed by my involvement in standards development, conformity assessment and competence assurance, including membership of the EAS Management Committee and relevant BSI, CENELEC and IEC committees. They should not be taken as representing the views of the Building Safety Regulator, BSI, CENELEC, IEC, the Energy Storage Association, the EAS Management Committee, Flexi-Orb, Certi-fi Schemes Limited, or any other organisation with which I’m associated... Significant changes In July of this year, the Building Safety Regulator strengthened its focus on Mandatory Technical Competence for individuals carrying out regulated work through self-certification schemes. The subsequent message for electrical businesses is straightforward: people should only undertake work when they can demonstrate the knowledge, skills, experience and behaviours required for the activities they’re authorised to perform. Business registration, company procedures and the oversight of a Qualified Supervisor remain important.

However, greater emphasis is now being placed on the competence of the individual carrying out the work. The updated Electrotechnical Assessment Specification (EAS) reinforces this direction, particularly in specialist areas such as solar PV, battery energy storage systems (BESS), EV charging equipment and micro-wind systems. A greater focus on the individual For many years, competence within an electrical business has often been judged through the qualifications, experience and oversight of the Qualified Supervisor. That role remains central to technical governance, quality assurance and compliance, but it cannot substitute for the competence of everyone else involved in the work. Businesses need to understand what each person is capable of doing, where supervision is needed and where further training or experience may be required. The key question is: can the individual demonstrate competence in the work they’re expected to undertake? That means looking beyond job titles and certificates. It requires evidence that the person can apply their knowledge and skills safely and consistently in practice. Competence must be present throughout the process, including design,

installation, inspection, testing, commissioning and certification. Qualifications remain an essential part of the competence picture, but they don’t automatically prove competence in every type of work. Solar PV, battery storage, EV charging and other low-carbon technologies introduce new equipment, risks, standards and design considerations. An experienced electrician may be highly competent in conventional installation work but still require additional training and practical experience before taking responsibility for the design or commissioning of an energy storage system. Competence combines technical knowledge, practical skills, relevant experience, professional behaviour, awareness of legislation and standards, understanding of manufacturer requirements and recognition of personal limitations. It must also be maintained. Standards change, products develop and working practices evolve. Evidence that was sufficient several years ago may no longer reflect the work being carried out today. Regulation 16 of the Electricity at Work Regulations 1989 requires those undertaking work where technical knowledge or experience is necessary to possess the knowledge or experience

PROFESSIONAL ELECTRICIAN September 2026 29

029_PE_SEPT26_Layout 1 30/07/2026 15:30 Page 30

SPECIAL REPORT needed to prevent danger. BS 7671 also requires electrical installation work to be carried out by individuals with appropriate education, training and practical skills. Competence must match the task Competence is specific to the activity being undertaken. For example, someone competent to install equipment may not yet be competent to design the system. Or, similarly, a person may be capable of working under supervision but not ready to inspect, commission or certify work independently. Experience in domestic wiring doesn’t automatically demonstrate competence in solar PV design. At the same time, experience in EV charging doesn’t necessarily demonstrate competence in energy storage, periodic inspection or micro-wind systems. Businesses therefore need to define the competence required for each activity. This is particularly important in specialist technologies, where system integration, protective measures, commissioning, product requirements and technology-specific standards may all need to be understood. A broad job title such as “electrician” can’t, on its own, demonstrate competence across every area of work. What evidence should be considered? Evidence should be relevant to the activity, proportionate to the risk and reasonably current. It may include: ● recognised qualifications; ● occupational competence assessments; ● manufacturer training; ● supervised workplace experience; ● practical observations and technical discussions; ● completed work, inspection and test records; ● continuing professional development; and ● evidence of working to current standards. A certificate may show that someone has completed training, but not necessarily that they can apply it safely and consistently in the workplace. Equally, an experienced electrician may demonstrate competence through work records, practical assessment, technical discussion and professional development without

30 September 2026

repeating a full qualification. The purpose is not to collect certificates but instead to build a credible picture of what the individual can do. The continuing role of the QS The move towards individual competence doesn’t reduce the importance of the Qualified Supervisor. The role remains vital in maintaining standards, supporting quality assurance and ensuring work is carried out in line with relevant requirements. Supervision should be used appropriately. It is reasonable for trainees, developing electricians and those moving into new areas of work to operate under supervision. The level of oversight should reflect both the risk of the work and the competence of the person undertaking it. What supervision cannot do is permanently cover gaps in competence. Businesses should therefore be clear about who is authorised to carry out each activity, what evidence supports that authorisation, where supervision is required, what limitations apply and when competence will be reviewed. Practical steps for electrical businesses A sensible starting point is to list the categories of work carried out by the business and identify everyone involved in designing, installing, inspecting, testing, commissioning and certifying that work. For each person, consider whether the available evidence matches their responsibilities. Where gaps are identified, they may be addressed through practical assessment, supervised experience, mentoring, technical discussion or further training. A competence matrix can record work categories, individual roles, qualifications, experience, assessment evidence, CPD, authorisation levels, restrictions and review dates. Used properly, it becomes a working management tool rather than a document produced only for an assessment visit. The same approach should apply to agency workers, labour-only operatives and subcontractors. Responsibility for establishing competence doesn’t disappear because someone is

PROFESSIONAL ELECTRICIAN

self-employed or temporarily engaged. An opportunity to strengthen the industry Handled well, these changes should improve safety, strengthen confidence in electrical work and give greater recognition to the people carrying out the work on-site. They can also support clearer development routes into specialist areas such as solar PV, energy storage, EV charging and other low-carbon technologies. For employers, a structured approach provides a stronger basis for allocating work, planning training and managing risk. The direction is clear - competence must be demonstrated by the people carrying out the work, not assumed from a business name, job title or qualification alone. The Building Safety Regulator’s Mandatory Technical Competence requirements and EAS 2026 provide an opportunity for electrical businesses to place evidence, authorisation and individual capability at the centre of their technical governance. Practical checklist ● Identify each category of work carried out by the business. ● Record who designs, installs, inspects, tests, commissions and certifies the work. ● Check that the evidence held matches each person’s responsibilities. ● Record qualifications, experience, assessments, CPD and authorisation limits. ● Address gaps through appropriate training, supervision, mentoring or assessment. ● Include employees, agency workers and subcontractors. ● Review competence when roles, technologies, standards or regulations change. ● Keep records current and use them to support day-to-day decisions.

SPECIAL REPORT

TO SEE YOU AGAIN

More than 30 years after PE first followed his Antarctic adventure – and a decade after reporting on Halley VI's dramatic relocation – we catch up with an electrician who continues to achieve cold feats.

ow many electricians can say they've helped keep one of the world's most remote scientiﬁc research stations running? Even fewer can claim to have done it over a career spanning more than 30 years. Yet that's exactly what Robert Curtis has achieved, after returning to Antarctica at the age of 61 for another deployment with the British Antarctic Survey (BAS), proving that experience and determination remain invaluable assets in one of the harshest working environments on Earth. More than 30 years after ﬁrst travelling to Antarctica with BAS, and a decade after helping relocate the famous Halley VI Research Station away from a dangerous crack in the Brunt Ice Shelf, the Barry-based electrician, who currently works for Cardiff Community Housing Association, has once again returned to the frozen continent. A journey that almost didn't happen Interestingly, this latest expedition was almost over before it started. Before being cleared to travel south, Rob had to pass BAS's demanding

medical assessment, which meant losing around 12 kg to reduce his BMI below the required limit. At the same time, he had been diagnosed with Type 2 diabetes and needed to prove he could control the condition through diet and exercise. Rob explains: “My biggest challenge for my last deployment south was my struggle against a Type 2 diabetes diagnosis and my determination to control my weight.

member in one of the most extreme environments the Earth has to offer.” Keeping science alive through the Antarctic winter Today, Halley VI operates as a summer-only station following major changes to the Brunt Ice Shelf. Around 40 personnel occupy the base between late November and early February, including scientists, engineers, electricians, plumbers, a doctor and support staff. Although everyone leaves before winter, the station continues operating autonomously as temperatures fall to -55°C. A microturbine generator supplies up to 30 kW of power to science modules housing climate experiments and communications equipment, all monitored remotely from BAS headquarters in Cambridge.

“Hours of gym work and hill walking allowed me to conquer this hardest of challenges, including manhauling a tractor tyre around Cardiff Bay. “There were times when I thought I would never see the majestic beauty of Antarctica ever again. But luckily, the British Antarctic Survey values experience and a proven ability to work as a team

PROFESSIONAL ELECTRICIAN September 2026 33

SPECIAL REPORT

That makes the electricians' work during the short summer season absolutely critical. “With Halley VI now operating autonomously throughout the Antarctic winter, it is more essential than ever that all electrical systems are checked and maintained during the short summer window period,” says Rob. “If electrical systems fail once we leave the station, there’s no going back to reset a breaker, which could lead to a science programme having to be aborted. “Engineers and scientists will be working constantly together at the BAS Cambridge headquarters to monitor remote signal readings to avoid any potential problems with the scientiﬁc equipment.”

Three decades of change With Antarctica itself changing faster than ever before because of human induced climate change, the technology supporting it has evolved dramatically. “The biggest difference over the last 30 years is the increased ability to communicate across the thousands of miles from the UK to Antarctica,” says Rob. “In 1996 we were restricted to a 500-word email every month with family, friends and our Cambridge headquarters, but in 2026 Starlink allows us to WhatsApp family and friends or ﬁnd the instructions for a piece of electrical equipment almost instantaneously.” He continues: “Despite those advances, the mindset of the maintenance team remains the same. You must be able to work as a team and be prepared to work through problems and make full use of the equipment and tools you have on station. Once the ship or

34 September 2026

plane departs, you’re on your own.” He also believes BAS is entering a new era of engineering. “By far the biggest change in the last 30 years is the ability to use satellite communication systems to both monitor and control the scientiﬁc experiments. “The next major change is the push to ensure that all of BAS's research stations are no longer powered by barrels of oil and are converted to renewables. In a place where solar and wind energy is so abundant, this change is long overdue.” Looking ahead, Rob believes drones and robotics will increasingly be used to undertake hazardous surveys and scientiﬁc work, although he hopes there will always be a place for human engineers on the ice. Lessons beyond Antarctica Although few electricians will ever experience Antarctica, Rob believes the qualities needed to succeed there are relevant to every installer. He says: “You don’t need to be a perfect electrician with knowledge of every electrical system or piece of equipment. “But you do need to work as a team and learn from errors because, as humans, we’re all destined to make mistakes.” Interestingly, Rob’s Antarctic experience has also provided an unexpected advantage back in the UK. “I always joke that having worked for BAS in Antarctica on your CV means all future job interviews become easy, because interviewers bored with asking the same technical questions suddenly ask you about penguins, seals and icebergs!”

PROFESSIONAL ELECTRICIAN

An adventure worth pursuing Reﬂecting on more than three decades with BAS, Rob remains immensely satisﬁed at the contribution he has made to climate science. “I’m extremely proud of my long career with the British Antarctic Survey and being part of such an excellent team which delivers reliable climate science to the world.” He also hopes his story encourages younger electricians to consider a very different career path. “I would urge any young electricians out there who like adventure and are not frightened of the cold to send their CV off and one hell of an adventure may unfold. “It is a privilege to work in Antarctica. You will make friends which will last a lifetime and you’ll also cherish some very special and unique memories.” And after six expeditions, could there be another? Rob replies: “Never say never. I know BAS values experience and dedication and, as the old rugby motto goes: 'Youth and enthusiasm is no match for age and treachery!' “Watch this space.”

SPECIAL REPORT For 75 years WAGO has built its reputation on trusted electrical connections. Here, we discover why the company believes automation will have a big part to play in shaping its next chapter, creating new opportunities for installers along the way.

DRIVING THE AUTO-MATIC

sk most electricians about WAGO and the ﬁrst thing that comes to mind is connectors. For generations, the company's products have become synonymous with making electrical connections quicker, safer and more reliable. That reputation has been earned over 75 years, during which time WAGO has grown from a family-owned business in Germany into a global engineering company spanning electrical interconnection, interface and automation technology.

While the anniversary is an opportunity to celebrate that heritage, WAGO's UK leadership believes its biggest opportunity lies ﬁrmly in the future. The business has more than tripled its UK and Ireland operation over the past seven years, investing heavily in people, facilities and technical expertise, including the opening of its new headquarters in Rugby. Alongside its established electrical offering, automation is now a key part of the company's long-term strategy.

Building on strong foundations Few businesses reach 75 years by simply standing still. From pioneering spring-pressure connection technology, WAGO has continually expanded its offer into interface electronics, control systems, building automation and industrial automation. Today, the business employs around 9,000 people globally, invests around 10% of annual revenue in research and

development and generated €1.34 billion in revenue during 2025. The UK business reﬂects that growth. Established in Britain since 1990, WAGO UK & Ireland now employs around 90 people and continues to expand from its purpose-built Rugby headquarters, where the company's own building management, lighting control and energy management technologies are showcased in practice. Darren Hodson, Managing Director of WAGO UK & Ireland, believes the company is now entering another important chapter. He says: "We're incredibly proud of our heritage, but we're equally excited about what's next. Customers know and trust WAGO because we've always focused on solving real problems. “Today's challenges are different – whether that's improving productivity, reducing energy use or making buildings and industrial processes smarter. That's where automation has such an important role to play."

SPECIAL REPORT

Why automation matters For many electrical contractors, automation can still feel like a specialist discipline, however, John Mackey, Head of Automation Sales at WAGO UK & Ireland, believes it should instead be viewed as the natural progression towards smarter, more connected electrical installations. He says: “There’s no doubt that the pace of technological change is accelerating for manufacturers. As a result, businesses need to become more productive, with better energy-efficiency, connectivity and more resilience. “WAGO brings together strong German engineering with an open automation philosophy which puts us in an excellent position to help businesses modernise without creating unnecessary complexity." That principle sits at the heart of WAGO's automation strategy. Rather than encouraging customers to replace existing infrastructure, WAGO focuses on open, scalable technologies that integrate with existing systems, allowing organisations to install, connect, monitor and automate in manageable stages. Its offer now extends well beyond hardware to include software platforms, custom engineering solutions, commissioning, cybersecurity, training and service support. “Customers aren't looking for technology for technology's sake," John continues. "They want practical solutions that improve performance and deliver value without disrupting their existing operations. That's exactly where we believe WAGO can make a real difference.”

Growth sectors WAGO has identified manufacturing, buildings and energy as three of its key strategic markets, with particular focus on applications such as energy management, room automation, cybersecurity, building decarbonisation and smart factories. The opportunities are significant. Food and beverage manufacturing remains the UK's largest manufacturing sector and continues to invest heavily in automation. Meanwhile, the UK's microgrid market is forecast to grow rapidly as organisations invest in renewable energy, decentralisation and greater resilience. At the same time, AI is driving unprecedented investment in data centres, creating growing demand for advanced power management, monitoring and control technologies. WAGO is already supporting many of these applications while continuing to develop products specifically for this expanding market. Opportunity knocks While these trends are often discussed in terms of manufacturers and end users, Darren believes they represent a major opportunity for electrical professionals.

He says: “Electrical contractors are increasingly involved in projects that bring together power, controls, networking and energy management. The installer's role is evolving, and with that comes the opportunity to offer customers better value than ever before." To support that transition, WAGO is investing in solution partners, technical resources, knowledge sharing and application expertise, helping installers develop the confidence to deliver sophisticated automation projects. John believes electricians are well placed to benefit from this development, stating: “The electrical industry has always adapted to new technologies, and automation is simply the next stage of that evolution. “Installers already have many of the core skills. By building knowledge around connected systems, software and energy management, they can position themselves at the centre of one of the industry's biggest growth areas." Looking ahead WAGO's ambition is to grow its UK business to £75 million by 2030, with industrial automation becoming a much larger part of that journey. For Darren, however, success will still be measured in the same way it has been for the past 75 years. “The technology may continue to evolve, but our focus remains exactly the same,” he concludes. “It's about understanding our customers, solving their challenges and helping them succeed. That's what built WAGO over the last 75 years, and it's what will define the next 75 as well.” BROWSE WAGO’S RANGE OF AUTOMATION PRODUCTS AND SOLUTIONS AT: WWW.RDR.LINK/ECB015

THE

CODEBREAKERS JOHN HOLLAND: WE CARRIED OUT AN EICR RECENTLY AND CAME ACROSS THIS… WHAT CODE WOULD YOU RECOMMEND? Whenever a kitchen refurbishment is undertaken the extent of the work needs to be considered, not just from an electrical point of view but from the location of base and wall units to determine any conflicts with existing services. This refurbishment didn’t consider the position of the existing electrical services where they clash with the new base and wall units and this has resulted in the accessories being partially blocked and some restricted access. With regards to functional switching, this may not be a major issue, as long as suitable means of isolation exists elsewhere. The cooker switch is poorly located for operation, although it’s normally good practice to provide one, there are no specific requirements for its presence.

GET THE BOOK AND CRACK THOSE CODES!

The main issue would be for maintenance, inspection and testing where the accessories are recessed and grouted in (where the tiles are covering the edges) and the wall and base units preventing the removal of the accessories. In the case of a faulty accessory, this would require removal of the kitchen units and potentially damage to the tiling to allow access to replace or repair the wiring or accessories. Potentially there may also be issues with the fixing of the wall and base units where any cable runs have been concealed within the wall. Although not good workmanship, and unfortunately an electrician may not have even been involved in the refurbishment, there is no immediate danger or a potential danger. Therefore, the appropriate classification code would be a C3, Improvement recommended.

Updated for BS 7671:2018+A2:2022, NAPIT’s EICR Codebreakers publication is purpose-written to aid contractors, inspectors and clients, and now includes updates to align with Amendment 2 of the IET 18th Edition Wiring Regulations.

DAVID HORN: (PIC 1) THIS NEUTRAL CARRIED POWER FOR A SHOWER BLOCK WITH A 9 KW ELECTRIC SHOWER ALONG WITH THE HOOK-UPS FOR A SIX-PITCH CARAVAN SITE. IT WAS SUPPLIED FROM A THREE-CORE 16 MM SWA CABLE WHICH HAD THE ARMOUR UNWOUND TO GET IT INTO THE BUILDING. (PIC 2) INTERESTING CABLE MANAGEMENT OF THE SAME SWA CABLE... It’s surprising how often conductors are installed into equipment with undersized terminals without the correct preparation of the conductor for a particular situation. The cutting of any of the copper strands of a conductor reduces the current carrying capacity of the conductor and can lead to thermal damage to the conductor and, in this case, the distribution board. Although not evident from the image, it should also be considered whether the circuit is undersized generally for the stated supplied load of a 9 kW shower and six caravan pitch supplies. The steel wire armouring of the SWA cable has been removed to allow entry to the building. This has removed the mechanical protection for the conductors (the covering to the conductors is bedding and is not a cable sheath for mechanical protection). It would be difficult to appropriately gland an SWA cable to the enclosure without any armouring present. This being an SWA 3-core cable with the 3rd core being utilised as a CPC may mean the SWA may not be required as a protective conductor, but it is still required for mechanical protection. The SWA is also not suitably glanded at entry to the enclosure and there is no means of protection against abrasion from the visible sharp edges at point of entry. The SWA conductors haven’t been correctly identified, red and yellow conductors. The SWA has not been adequately supported against premature collapse due to the use of non-proprietary cable supports. Therefore, the appropriate classification code would be a C2, Potentially dangerous-urgent remedial action is necessary due to the cable installation.

THE CPD ZONE

IZ AND IT EXPLAINED This article from the experts at NICEIC aims to clarify the difference between the various terms used to describe the current-carrying capacity of conductors and to demonstrate how they are both used to determine a suitable cross-sectional area (CSA) of conductor, taking account of any relevant correction factors.

hen selecting a suitable cable for the circuit's current, two methods can be used. The first involves selecting a cable based on its tabulated current-carrying capacity (It) and then applying any applicable correction factors to determine its current-carrying capacity under the actual installation conditions (Iz). This will typically require several attempts to arrive at a satisfactory solution and is not recommended. The second, and arguably more effective, method involves applying the correction factors to the rated current or current setting of the protective device (In) and then selecting a cable that can carry the current value obtained from this calculation. Determining a suitable CSA for a conductor involves more than just considering the current; factors such as the impedance and voltage drop of the circuit are also important. However, this article simplifies the design process to focus solely on current-carrying capacity. Protecting a circuit from overload Every circuit shall be designed to ensure there is sufficient protection from overload. Other than when a fixed load is used, this is generally achieved by using a suitable overcurrent protective device. When selecting a cable for a circuit and using a device listed in Regulation 433.1.201, such as a circuit-breaker, protection from overload current can be

achieved by satisfying the requirements of Regulation 433.1.1 and the following conditions: Expression 1

Ib ≤ In ≤ Iz Where: Ib is design current of the circuit; In is rated current or current setting of the protective device; and Iz is current-carrying capacity of a cable for continuous service under the particular installation conditions concerned. Once the design current has been determined, the protective device rating can be selected and then the current-carrying capacity of the cable.

“Determining a suitable CSA for a conductor involves more than just considering the current...”

Determining the current-carrying capacity of a cable (Iz) Appendix 4 of BS 7671 - Current-Carrying Capacity and Voltage Drop for Cables is an informative part of BS 7671 to aid designers in selecting suitable cables. To find Iz, the following five steps should be taken: 1. Select the correct table from Appendix 4 Identify the relevant table for the cable type to be used. Due to switchgear considerations, this is usually a table representing 70 °C conductor operating temperatures. For example, when using a multicore steel wire armoured cable, reference Table 4D4A. 2. Select the applicable reference method Follow the first row and select the correct installation reference method. 3. Select the correct column for the number of conductors For each reference method there are two columns – one for single-phase, and one for three-phase. Select the relevant column.

THE CPD ZONE 4. Find the tabulated current Follow the table downwards to identify a tabulated current that is equal to or greater than the protective device rating (In). 5. Follow the row from right to left to reach the first column of the table Follow a horizontal line from the tabulated current to the first column; the first column represents the CSA of the cable. Using the five steps process outlined here, a cable is selected based on its tabulated current rating (It). To find the Iz of this cable, the relevant correction factors are to be applied to It as shown in Formula 1. Iz = It x Cg x Ca x Cs x Cd x Ci x Cf x Cc Where: Iz is current-carrying capacity of a cable for continuous service under the particular installation conditions concerned; It is tabulated current-carrying capacity of a cable; Cg is rating factor for grouping; Ca is rating factor for ambient temperature; Cs is rating factor for thermal resistivity of soil; Cd is rating factor for depth of burial; Ci is rating factor for conductors embedded in thermal insulation; Cf is rating factor for semi-enclosed fuse to BS 3036; and Cc is rating factor for circuits buried in the ground. Formula 1. General Iz calculation

Using the ‘Iz method’ detailed in this section involves trial and error, as the current-carrying capacity of the cable can be greatly reduced depending on the correction factors applied. If the value falls below the protective device’s rating (In), a larger CSA cable is selected and the calculation is carried out again. Only when Iz is greater than In is the cable suitably provided with protection from overload. Example A steel wire armoured cable (Table 4D4A) serving a single-phase 30 A load is grouped with another circuit and runs through a plant room with an ambient temperature of 40 °C. The cable is clipped direct, and the circuit protective device is suitably selected and rated at 32 A. Using the ﬁve-step method described previously, a cable with a 4.0 mm2 conductor is ﬁrst selected as it has a tabulated current-carrying capacity of 38 A. Using Formula 1 with only the relevant correction factors applied, Iz is calculated in Equation 1: Iz = It x Cg x Ca x Cs x Cd x Ci x Cf x Cc Where: Cg = 0.87 40 °C ambient temperature. 70° C thermoplastic insulation (Appendix 4. Table 4B1; and Ca = 0.85 two circuits. Single layer on a wall (Appendix 4. Table 4C1) Iz = It x Cg x Ca Iz = 38 x 0.85 x 0.87 Iz = 28 A Equation 1. Worked Iz calculation

This cable would not be suitable as Iz < In,

therefore the calculation would need to be repeated with the cable having the next largest CSA. This method can require several iterations to determine a suitably sized conductor. In the case of this example, the next larger CSA conductor is 6 mm2 (It, 49 A). If the calculation is repeated for this cable, the Iz is 36 A, which would be suitable. Selecting a cross-sectional area using the It method There is a quicker method to determine a suitably sized conductor, which removes the trial-and-error process described previously. Instead of applying the correction factors to a selected cable, this method involves dividing the rating of the protective device by the applicable correction factors. The resulting value is then used to ﬁnd a tabulated value that is equal to or greater than it. This is shown in Formula 2. It ≥

In Cg x Ca x Cs x Cd x Ci x Cf x Cc

Formula 2. General It calculation

Using the previous example, this calculation is carried out in Equation 2. It ≥

It ≥

In Cg x Ca

32 0.85 x 0.87

It ≥ 43.3A Equation 2. Worked It calculation

The result from the calculation indicates that a cable with a tabulated current-carrying capacity equal to or greater than 43.3 A will be suitable. Following the ﬁve-step process from the previous section, but replacing the In value with the numerical value obtained using Equation 2, will help to select the appropriate cable. Fig 1 illustrates this method and shows that a cable with live conductors having a CSA of 6.0 mm2 and a current-carrying capacity of 49 A is required. This value can sometimes be confused as the value for Iz. When the cable is selected using this method, the designer would not necessarily need to know the value of Iz. Using the It method, it is unnecessary to calculate Iz during the conductor selection and therefore Formula 1 need

045_PE_SEPT26_Layout 1 30/07/2026 08:44 Page 47

Now that Iz has been obtained, the conditions for overload protection given in 433.1.1 (a) and (b) can be veriﬁed using Expression 2: Ib ≤ In ≤ Iz 30A ≤ 32A ≤ 36A Expression 2. Verification of overload protection

not be applied. However, If the designer wishes to calculate Iz and verify compliance with Regulation 433.1.1, the applicable rating factors can be applied to the value of It for the cable selected, as shown in Equation 3:

Iz = It x Cg x Ca x Cs x Cd x Ci x Cf x Cc Iz = It x Cg x Ca Iz = 49 x 0.85 x 0.87 Iz ≈ 36 A Equation 3. Worked Iz verification calculation

Summary The article explored two common methods of determining the cross-sectional area of a conductor based on the current-carrying capacity. The It method can involve fewer steps than the Iz method and may be preferred, although with this method the value of Iz is not known unless a further calculation is performed.

Q: I’m designing a ﬁre detection and alarm system from plans, but the building isn’t yet occupied. How do I estimate the likely ambient sound levels in the different areas? Does BS 5839-1:2025 provide any guidance?

● Restaurants: 72–75 dB(A) ● Commercial kitchens: 65–75 dB(A) ● Quiet cafeterias: 55–65 dB(A) ● Noisy cafeterias: 68–78 dB(A)

Yes. BS 5839-1:2025 Annex C provides typical occupational background noise levels for many common building types and areas. This is particularly useful when the system is being designed from drawings, and it isn’t yet possible to take representative sound-level measurements in the completed, occupied building. The ﬁgures are expressed as typical A-weighted sound pressure levels, Lp, in dB(A). Examples include:

● Noisy, uncarpeted corridors:

Corridors and circulation spaces ● Quiet, uncarpeted corridors:

45–55 dB(A)

Offices and general working areas ● Cellular offices: 40–50 dB(A) ● Open-plan offices: 50–70 dB(A) ● Noisy offices: 70–85 dB(A) ● Conference/meeting rooms:

40–45 dB(A)

66–76 dB(A) ● Carpeted corridors: 28–32 dB(A)

The difference between a carpeted and uncarpeted corridor can be substantial and shouldn’t be ignored during design. Leisure and sports facilities ● Squash courts: 65–80 dB(A) ● Ice rinks during public sessions:

69–80 dB(A) ● Swimming or diving pools: 72–79 dB(A) ● Fun pools: 81–87 dB(A) ● Bowling areas: 78–85 dB(A) ● Quiet sports halls: 60–72 dB(A) ● Noisy sports halls: 72–82 dB(A) ● Sports halls during loud ball games:

78–93 dB(A)

● Courtrooms: 40–50 dB(A) ● Exhibition halls: 63–73 dB(A)

Educational buildings ● Quiet classrooms: 56–68 dB(A) ● Noisy classrooms: 64–72 dB(A) ● Quiet library book or reading areas:

35–45 dB(A) ● Noisy or heavily air-conditioned library areas: 50–60 dB(A) ● Library reception areas: 50–60 dB(A) Hospitals and hotels

For hospital wards and hotel bedrooms: ● Television switched off: 28–35 dB(A) ● Television switched on: 60–70 dB(A) This illustrates how signiﬁcantly the expected background noise can change depending on how the room is being used.

Retail buildings ● Quiet shops or stores: 50–60 dB(A) ● Noisy shops or stores: 65–75 dB(A) ● Shopping malls: 70–75 dB(A) ● Banks and building societies, public

areas: 50–64 dB(A) Factories, warehouses and plant rooms Factories: ● Control rooms: 70–75 dB(A) ● Light assembly areas: 80–85 dB(A) ● Heavy engineering areas: 95–105 dB(A)

Plant rooms: ● Quiet boiler rooms: 66–72 dB(A) ● Noisy boiler rooms: 76–86 dB(A) Warehouses: ● Quiet warehouses: 47–63 dB(A) ● Noisy warehouses: 63–80 dB(A) How should the ﬁgures be used?

Dr. Zzeus, Tom Brookes, answers another fire-related reader query

Annex C figure as an initial estimate of the sound level the fire alarm must overcome. For example, if an open-plan office is expected to have a background noise level of up to 70 dB(A), the fire alarm design must take that expected noise into account when determining the required alarm sound pressure level and the number and positioning of sounders. However, Annex C is informative guidance. It is not a replacement for proper sound-level measurements. Noise levels can vary significantly between apparently similar buildings and can also change with occupancy, equipment operation, and the time of day. The standard advises that, where Annex C is used to assess a fire detection and alarm system, the higher of the two quoted figures should normally be used as the appropriate design value. Wherever reasonably practicable, actual measurements should subsequently be taken in the building under representative operating conditions. Dr ZZEUS Tip: Annex C doesn’t specify the sound level the fire alarm must achieve. It tells you the likely background noise that the alarm will have to overcome. It is therefore an excellent starting point when designing from plans, but the designer must still apply the audibility recommendations of Clause 16, consider the intended use of every area and verify the completed installation under realistic conditions.

DOES AN RCCB TYPE B TRIP ON DC? Martin Plumbridge TMIET, Technical Manager at Doepke, highlights why taking a few extra minutes to verify Type B RCD DC tripping performance could enhance electrical safety.

e‘ve witnessed an increase in reports from several well-informed installers relating to Type Bs that don’t function correctly in the presence of DC components. For example, one design was marked as bidirectional but failed a smooth DC tripping test. Although the basic requirements of BS 7671 don’t require veriﬁcation that the Type B RCD protection feature works, it would seem prudent to spend a few minutes checking that modern complex domestic systems, costing possibly £10,000 or more, are protected by a functioning RCD. A simple test with the correct instrument can be performed to verify that the RCD trips when subject to smooth DC.

RCD tests and thresholds The existing BS7671 1 x RCD veriﬁcation test required for example for 30 mA RCDs relates to an AC sinusoidal residual current, irrespective of the type of RCD. ● All RCCBs subjected to 50 Hz residual current are designed to trip between >50% - <100% IΔn, which equates to 15 to 30 mA. The max switch off time at 1 x is 0.3s. ● Type A, type F, and type B pulsed residual current (50 Hz); the tripping current threshold changes to >35% - < 140% IΔn. Type A (BS EN 61008-1) must still trip with the pulsed waveform superimposed on 6 mA smooth DC. Type F (BS EN 61008-1 and BS EN 62423) must still trip with the pulsed waveform superimposed on 10 mA smooth DC. Type B (BS EN 61008-1 and BS EN 62423) subjected to smooth DC residual current must trip between >50% - <200% IΔn i.e. for 30 mA equates to 15 < 60 mA DC on both cycles 0° and 180°.

The standards deﬁne the tripping thresholds and times based on the residual current components. Although BS 7671 only requires veriﬁcation of the AC trip threshold irrespective of the type, Michael Peace’s IET Article in Issue 91 July 2022 explains that other tests are not precluded. Why DC tripping characteristics matter RCD Types A and F use a magnetic core to detect imbalance between live and neutral conductors. Smooth DC residual current above the design current can saturate this core – a phenomenon known as DC blinding. When the core is saturated, The RCD becomes insensitive to further imbalance. Trip thresholds increase unpredictably; the device may fail to trip entirely. This is a major safety concern because a circuit could carry a dangerous fault current without any protective disconnection. Type B RCDs are designed to detect smooth DC and trip when it exceeds the default value. This maintains sensitivity to both AC and pulsating DC components while also responding to pure DC leakage. Test instruments For test instruments equipped with a Type B RCD setting, a multiplier of 2 × IΔn is applied in accordance with the product standard BS EN 62423. We have witnessed an increase in complaints relating to a number of type Bs that do not function correctly in the presence of DC components – particularly those that are marked as bidirectional. A simple test can be performed to verify DC tripping on DC currents.

Repeat the same test on the opposite side of the unit. For a true bidirectional RCD it should still trip to the relevant parameters.

Testing procedure for Type B RCDs The testing procedure for a type B RCD is relatively straightforward from connecting the live, neutral and earth to probes the appropriate terminals on the load side and carrying out the tests. Once complete, carry out the same test on the supply side to check the device is true bidirectional. Carry out the standard AC test ﬁrst (following all testing safety procedures). DC Tripping test applicable to any 2-pole 30 mA type B (Outgoing circuit should be disconnected). To measure RCD tripping current on a Fluke 1654B 1. Turn the rotary switch to IΔn position. 2. Press F1 to select the test current phase, 0° or 180°. 3. Press F3 to select the RCD test-current waveform: smooth – DC current to test type B RCD. 4. Press F4 to select the RCD current rating (10, 30, 100, 300 or 500 mA). 5. Press and release ‘test. Wait for the test to complete.

Conclusion So, does a Type B RCCB trip on DC? Well, the answer is that it should do, but some don’t. If it is detecting DC it should trip between >50% - <200% IΔn, which equates to 15 to 60 mA range on both cycles 0° and 180° for 30 mA device. If it is truly bi-directional it will trip on DC, irrespective of which side you connect the supply. The testing procedure for a Type B RCD including DC test takes a few minutes in addition to the standard AC test. If it is a complex installation requiring Bi-directional RCD functionality you can verify the operation by repeating the test on the reverse side As you can see here, it’s worth a few additional minutes checking that your modern complex domestic system and the people using it are adequately protected by the RCD you have speciﬁed and installed.

MAXIMUM DEMAND & DIVERSITY

or economic and reliable design of an installation within thermal limits and admissible voltage drop Regulation 311.1 of BS 7671 requires, the maximum demand shall be determined. In determining the maximum demand of an installation or part thereof, diversity may be taken into account.

In this article, Jake Green, Head of Technical Engagement at Scolmore Group, looks at the effect diversity can have on the maximum demand of an installation.

Determining loads When considering maximum demand, firstly we must look at the current demand of our final circuits. This is determined by adding the current demands of all points of utilisation and the associated equipment and then assessing the overall power or current. This is typically calculated from the connected load, or in the case where the actual load is unknown, such as with a ring final circuit, the protective device for that specific circuit. Consider, for example, the current of a 6 kW freestanding cooker: P=I V

6000 = 26.08 𝐴 230

It is unlikely that a cooker circuit will draw the full load current for the period the cooker is in use. By way of an example, any electric cooker or hob will not draw much current when the desired temperature has been reached. Only the current necessary to maintain temperature will flow. If this was not taken into account, the number of circuits that could be installed in an installation would be reduced greatly. Because of this the designer of an electrical installation can consider diversity as they assess the maximum demand of an installation (311.1). How is diversity applied? When taking diversity into account, BS 7671 does not provide guidance of values to utilise when applying diversity. To do this guidance from other publications, predominantly The Onsite Guide or Guidance Note 1, is used for the calculation of diversity. These values are guidance, and designers may use

engineering judgment and experience or sometimes referral to manufacturers’ data are used. In this article we will concern ourselves with The Onsite Guide. Appendix A of The Onsite Guide Table A1 is used to assume the current demand of the points of utilisation and current using equipment: Taking the example from the prevous page, using Table A1 we can see that household cooking appliances can be assumed to be the ﬁrst 10 A of the rated current plus 30% of the remainder of the rated current, plus 5 A if a socket-outlet is incorporated within the control unit (Cooker Switch). This means that the assumed current demand is as follows: 10 + (30% of the remainder ) +5 = Current Demand 26.08 𝐴 – 10 = 16.08 𝐴 10 + (30% of 16.08) + 5 = Current Demand 10 + 4.82 + 5 = Current Demand 10 + 4.82 + 5 = 19.82 𝐴 Now we can see the current demand assumption can be classiﬁed to be 19.82

A which has a rather signiﬁcant difference to the rated current of the appliance. This takes into consideration the type of load and its characteristics. Similar calculations can be carried out with other types of load. There are potential issues in following the guidance issued in The OSG. For example, the value of 100 W per luminaire is based on lamps which are no longer in use (tungsten ﬁlament). Many modern lighting circuits supply LED lamps or strips and the nature of the load is determined by both the lamp/strip and the driver. When applying diversity, however, we can take guidance from Table A2 of The Onsite Guide: For lighting from Table A2 under the heading types of premises, a guide of 75% of the total current demand can be applied for diversity for small hotels, boarding houses, guest houses, etc. Once diversity is applied to all circuits within an installation, it’s clear to see how this can dramatically lower the maximum demand and provide a somewhat closer value to what the measured value of

current drawn might be over time. However, experience may indicate that the values given in these tables are excessive, and the experienced designer may apply other factors to further reduce the assessed maximum demand. Vigilance should be used from Table A2 as some speciﬁc loads are not advised to allow for diversity due to the nature of the loads, such as thermostatically controlled water heaters in an individual household. Conclusion When obtaining the maximum demand of an installation in accordance with Regulation 311.1, it is important to recognise that the assessed current demand will not be fully utilised over a 24-hour period, and therefore diversity may be applied to determine a more realistic maximum demand.

Fig 1: Regulation 522.6.202 (P152 BS 7671: 2018 + A4: 2026).

Jonathan Swain, Technical Commercial Engineer at NAPIT, explains the requirements of BS 7671 when routing and concealing cables within a building’s fabric. He highlights the importance of understanding permitted cable zones, mechanical protection and external influences to minimize the risk of damage, ensuring safety and compliance throughout electrical installations.

HIDDEN DANGERS T

he ability to correctly route cabling within an installation is a key skill for any installation electrician. This article considers the requirements of BS 7671 when cabling is concealed within the fabric of the building, to reduce the risk of impact to our wiring systems – or, as it’s more conversationally referred to, reducing the risk of our cables being screwed or nailed into. In this article, we will not be considering Building Regulations compliance, although this must, of course, be adhered to in addition to BS 7671 requirements to ensure that our installations do not compromise the structural integrity or fire safety of a building.

External influences Part 3 of BS 7671 requires the designer of an electrical installation to assess the external influences to which the installation will be subjected. In appendix 5, we are provided with three general categories: environment, utilisation and construction of buildings. Further detail is then provided for external influences that may apply within these categories. Correctly identifying these influences the designer to select and erect the installation to meet requirements. For example, the reason routing cabling through cavity walls is considered inadvisable is that, when considering ‘environment’ as an external influence, a designer must account for flora (AK) and fauna (AL). The reason PVC twin and earth cabling is not installed externally is its lack of suitability for UV exposure – solar radiation (AN), etc. When wiring systems are embedded within the building fabric, the external influence of impact is a primary concern. Even within low-risk domestic or light commercial environments, there is still potential for mechanical stress due to the risk of penetration to a concealed wiring system.

This is of particular note when considering another external influence in domestic properties – utilisation. Most users of domestic installations, for example, will be of capability BA1 (Ordinary) and may be less able to perceive and mitigate risk of damage to the installation than someone who is BA5 (Skilled). As a general requirement, BS 7671: 2018 +A4: 2026 states in Regulation 522.6.1 that: ‘Wiring systems shall be selected and erected so as to minimise the damage arising from mechanical stress, e.g. by impact, abrasion, penetration, tension or compression during installation, use or maintenance.’ As electricians, we should always be mindful of how and where wiring systems are installed, regardless of the specific requirements reviewed in this article.

Cables concealed in walls In Amendment 4, Regulation 522.6.202 now sets out the requirements for correct routing and installation of cables (in a wall or partition) in a clear and easy to understand table format (Fig 1). The requirements remain the same with

selection and erection decisions informed by the installed depth i.e. less than or greater than 50 mm and whether or not the wall is constructed of metallic parts. In this Regulation, we ﬁnd the familiar descriptions of the cable zones prescribed when concealing cables in walls, as shown in Fig 2. The intent of indent (i) of the Regulation is to make it more likely that users of the installation will be able to identify the cable route and avoid damage when drilling or nailing into the structure. Accessories can create permitted zones horizontally and vertically from an accessory. The corners formed by walls and ceilings can also be used (up to 150 mm) because it is less likely that this part of the wall will be used for hanging shelves or pictures. However, additional care must be taken when kitchen units and the like are installed, as these are often within the 150 mm of a wall.

Fig 4: Alternative solutions as per Regulation 522.6.204 (P152 BS 7671: 2018 +A4: 2026)

NAPIT Technical Tip: Where an accessory is used to create a prescribed zone, it is only valid if there is cable connecting to that accessory indicating the zone presence. The presence of an accessory alone does not automatically create cable routes vertically or horizontally. In Fig 3, we can see an example where a cable zone has been ‘borrowed’ from the socket below to run cabling for an outside light on the reverse of the wall. The problem with this is that if that socket were to be opened to determine cable routes, any future users would only identify cabling running down the wall from the socket – with no indication of an additional cable concealed above. The intent of the regulation will not have been met, and users of the installation are not given the opportunity to avoid the risk of damaging the wiring system.

“Most electricians will recall a call-out to a homeowner who has nailed through a cable when hanging pictures.” Although commonly referred to as such, there is no such thing as a “safe zone” – there are, however, prescribed zones. Most electricians will recall an out-of-hours call-out to a homeowner in distress who has nailed through a cable when hanging pictures! For this reason, the regulation also requires additional protection by means of a suitable RCD. As can be seen in Table 52.1 (Fig 1): where additional protection (by means of a 30 mA or less RCD) is not provided, perhaps because of selectivity considerations, an alternative option is given to comply with Regulation 522.6.204 (Fig 4). It should be noted that where a wall or partition has metallic parts there will still be a requirement to install in prescribed zones. Of the options shown in Fig 4, the most likely to be achievable is the provision of sufficient mechanical protection to protect the wiring system or earthed metallic covering so that, in the event of cable damage, automatic disconnection of supply (ADS) is achieved. If mechanical protection alone is provided, it must be sufficient to withstand the likely impact, and with modern power tools, this can be difficult to achieve. Fig 5 displays how earthed metallic protection can be provided by using Steel Wire Armoured Cable (SWA) and earthed metallic conduit.

Fig 6: Regulation 522.6.201 (P151 BS 7671: 2018 + A4 2026)

Cables in floors and ceilings For cabling installed in floor or ceiling structures, BS 7671 does not provide permitted cable zones as it does for walls and partitions. In these cases, Regulation 522.6.201 applies (see Fig 6). Cables need to be installed so they are unlikely to be damaged. For example, securing cables near the top or bottom of

joists where missed plasterboard or floorboard fixings could present a hazard is unlikely to meet this requirement. Where cabling passes through a joist or ceiling support, it must be at least 50 mm from the top or bottom of the joist to avoid damage from ﬁxings above or below. If this cannot be met, we return to Regulation 522.6.204, where the options are again to provide sufficient mechanical protection or use a suitable earthed wiring system or covering (see Fig 7). NAPIT Technical Tip: Proprietary ‘safe plates’ are unlikely to meet the requirements of 522.6.204 – particularly given the widespread use of power tools, nail guns etc. Guidance suggests a steel covering of a minimum 3 mm thickness. If this is a chosen method of protection, the designer must decide whether this is sufficient. It is important to note though, as stated in the regulation, if earthed mechanical protection is used as the means of compliance, it must meet BS 7671 requirements for a protective conductor for the circuit.

This may apply where the use of existing notches or holes cannot be avoided. The use of RCDs is not a substitute for these requirements. Fig 8 shows an example of a cable protection safe plate, however, these may not meet current safety requirements. Conclusion Correct positioning of cables can often be challenging for installers. When routing a concealed wiring system through a building, electricians must navigate not only Building Regulation compliance but also BS 7671 requirements to achieve fundamental electrical safety.

LIGHTING LED strip lighting offers almost limitless design possibilities, but with so much choice, selecting the right solution can seem daunting. In this article, the team at Integral LED simplify the speciﬁcation process and explain how choosing the right LED strip system can be far easier than many installers expect.

GETA GRIP OF THE STRIP

he rise of COB (Chip-on-Board) LED strip has helped transform modern lighting design. From social media-inspired residential projects to retail, hospitality and commercial environments, seamless linear lighting has become one of the most requested lighting features by clients and specifiers alike. LED strip lighting can create everything from subtle mood lighting and feature illumination through to functional task lighting and large-scale architectural effects. However, whilst the finished result often appears simple, selecting the correct products requires an understanding of output, IP ratings, drivers, profiles and controls. So, where do you start when a client asks for LED strip lighting as part of their project?

At ceiling height, you'll typically need a similar output to a downlight – usually between 600 and 1,000 lumens per metre. If the strip is being used indirectly, such as within a ceiling cove or recessed niche, a higher output may be required to achieve the desired effect. Under kitchen cabinets, shelving, staircases and joinery applications, the strip is positioned much closer to the illuminated surface, so lower outputs are often sufficient. In many cases, 400-650 lumens per metre provides the ideal balance between functionality and visual comfort.

Choosing the right LED strip The ﬁrst question to ask (and usually the easiest to answer) is: “Where is the strip going?”

66 September 2026

White Digital Chasing creates dynamic lighting effects that add movement and energy to modern spaces and environments.

Choosing the correct colour temperature can inﬂuence the mood of a space and elevate the overall design.

The next consideration is IP rating. Fortunately, the same principles that apply to downlights also apply to LED strip. For dry environments such as living rooms, offices and meeting rooms, IP20 products are usually suitable. Bathrooms, kitchens and areas where splashing may occur should typically use IP65-rated strip, whilst outdoor installations and locations exposed to the elements are often best served by IP67 solutions. The second key question determines which driver you'll need: “How much LED strip is required?” If the chosen strip consumes 10 W per metre and the installation requires 15 metres, the total load is 150 W. As a rule of thumb, allow an additional 10% capacity to ensure the driver is not operating continuously at maximum load. In this example, a 165 W driver would be appropriate. The next step is to consider maximum run lengths. Standard COB strip often runs up to 5 metres from a single feed point before voltage drop becomes a concern. If longer runs are required,

쑮 Ultralong MAX enables continuous runs of up to 30 metres from a single driver, helping simplify larger LED strip installations.

installers may need to power the strip at multiple points or specify specialist long-run solutions. Products such as Ultralong MAX help overcome this challenge, supporting continuous COB runs of up to 30 metres powered from a single end or up to 60 metres powered from both ends. Planning the installation Which brings us to the next question: “How are you going to wire it?” Most LED strip installations rely on drivers concealed within ceiling voids, cupboards or service areas. Planning the location of these components early can simplify installation and make future maintenance significantly easier. Choosing the right connector system can also save valuable installation time. Crimp connectors with integrated cables eliminate the need for soldering and allow straightforward connections back to the driver. Corner connectors and flexible linking accessories can further simplify installations where layouts need to follow changes in direction. Once the strip, driver and connectors have been selected, there is one final consideration: “Which profile will you use?” Every LED strip install needs a profile, just as a GU10 lamp requires a fitting. Aluminium profiles protect the strip, help dissipate heat and provide a more reliable mounting surface. Wooden shelving, painted surfaces and kitchen cabinetry may all suffer from reduced adhesion due to dust, oils or surface finishes, making profile an essential part of a professional installation. Installers can typically choose between surface-mounted, recessed and plaster-in profiles depending on the application. The best manufacturers will clearly identify which strips are compatible with each profile, helping to simplify specification. Finishing touches For electricians who need additional flexibility, there are several specialist strip options available.

Looking ahead As customer expectations continue to evolve, LED strip lighting is increasingly being specified as a primary lighting source rather than simply an accent feature. Installers are being asked to deliver seamless lighting effects, flexible control options and cleaner architectural finishes across a growing range of projects. Having access to a comprehensive ecosystem of strip, drivers, controls, connectors and profiles can simplify specification whilst ensuring compatibility throughout the installation.

Bendy LED strip delivers smooth curves and warm accents for detailed architectural and interior applications.

Free Cut LED strip can be cut at virtually any point along the strip, reducing waste and removing the limitations associated with traditional cut intervals. This makes it particularly useful for shelving, joinery and bespoke installations where precise lengths are required. Longer runs become easier to achieve with products such as Ultralong MAX, whilst RGBW strip allows colour-changing effects to be introduced into a project. For applications that require changing colour temperature throughout the day, CCT Tunable strip provides the ﬂexibility to adjust from warmer to cooler white tones. Digital strip takes this a step further by introducing movement, chasing effects and dynamic lighting scenes that can transform the atmosphere of a space.

NO STRINGS ATTACHED

Joshua Hammerton, Co-Founder of Enkin, explains how the company's latest Kinetic lighting controls are redefining wireless switching with smarter functionality, faster installation and greater flexibility for retrofit projects.

t Enkin, we’ve always believed lighting controls should make life easier for electricians, while offering smarter, more ﬂexible solutions for customers. That’s why we’re excited to launch our new range of Kinetic receivers, designed to work with decorative toggles, push button, rocker switches and plastic paddle switches in collaboration with two of the UK’s leading switch and socket companies, The Soho Lighting Company and Lieber. These new switch modules combine self-powered Kinetic technology with our intelligent lighting control technology and advanced safety features. Until now, wireless Kinetic switches have largely been restricted to basic on/off functionality. We wanted to change that. Our new modules remove that limitation by supporting a broader range of lighting control solutions, including dimming, smart control, dual-channel switching and double-pole switching.

Designed to make installations quicker, cleaner and more flexible, the switch generates its own energy every time it is pressed, removing the need for batteries or wiring to the switch. It then wirelessly communicates with our new Kinetic receivers, giving electricians a simple solution for both new installations and retrofit projects. Keeping disruption to a minimum The benefits for electricians are plenty. There are no chasing walls to run switch cables, no batteries to replace and far less disruption when adding or relocating lighting controls. It's particularly useful for listed buildings, renovations and properties where rewiring is difficult or simply not practical. As an electrician, I've spent years seeing the same challenges on-site. Running cables isn't always practical, especially on retrofit projects where time, disruption and cost all add up. We wanted to create something that genuinely makes life easier for electricians while giving

customers a smarter way to control their lighting. By combining Kinetic energy harvesting with our dimming technology, we've developed a completely new way of thinking about lighting control. Our mission at Enkin is to become the market-leading brand in retrofit lighting and controls, bringing intelligent, easy-fit solutions to every home and space. This new product range combines elegant switch design with our intelligent, award-winning technology to deliver smarter, next-level lighting control. We've built the Kinetic switch on Enkin's reputation for developing intelligent lighting controls that simplify installation and solve everyday challenges on-site. Following the success of our award-winning dimming products, we've once again challenged conventional lighting control by removing the need for traditional switch wiring without compromising on performance. The next step in lighting control Our Kinetic Switch and Receiver range represents the next step in lighting control technology, combining battery-free switching with intelligent dimming in one simple solution. As demand for retrofit-friendly and energy-efficient solutions continues to grow, we believe Kinetic dimming technology is set to play an important role in the future of lighting control. The new Kinetic product range launches this month.

LISTENING, LEARNING AND LIGHTING THE WAY

f you were looking at Lumineux from the outside, you might describe the last few months as a busy period of innovation. We’ve introduced our new Apex range, launched LumiWave and, with LumiSmart also joining the portfolio this year, broadened the solutions we can offer customers. From inside the business, however, I’d describe it less as a period of innovation and more as a period of listening. One thing that has stood out to me since joining Lumineux is how close the business is to its customers.

With a number of significant developments taking place at Lumineux, David Street, Head of Marketing, explains why listening to the industry remains at the heart of the company’s plans for growth. Conversations with contractors, wholesalers and end users have always been important and I’m keen that we continue building on that. Listening means more than asking customers what products they want. It’s about understanding the challenges they face, where time is being lost and where we can make their working lives easier.

Apex and LumiWave are good examples of that thinking, although they approach it from completely different directions. Changing the habit With Apex, we weren’t trying to reinvent the bulkhead. There’s only so much you can do with that type of product. It needs to be reliable, do its job and, importantly, be something electricians are happy to ﬁt. Rather than trying to change what a bulkhead is, we focused on how electricians actually install them. We looked at the installation process and asked where we could make life easier. If we could create a product that was straightforward to work with and something contractors would pick up because they knew it was easy to ﬁt, then we’d achieved what we set out to do. That thinking is where our ‘Change the Habit’ campaign came from. We want installers to look again at a product they may buy automatically and consider whether there’s an option that can make their working day simpler. I think sometimes there is too much focus within our industry on what’s new rather than what’s genuinely useful.

LIGHTING

Contractors often appreciate products that are well thought through, reliable and easy to use. If improving an existing product delivers more value than adding another feature for the sake of it, that’s what we’ll do. A smarter approach LumiWave has been developed to solve a very different challenge. Emergency lighting testing, record keeping and compliance all take time and can create a signiﬁcant administrative burden, especially across larger buildings or multiple sites. LumiWave helps automate much of that process, giving contractors, facilities managers and building owners better visibility of their emergency lighting systems while reducing the administration involved. Technology is moving quickly across the electrical industry, with growing demand for smarter, connected and energy-efficient installations. However, I don’t think many contractors get out of bed in the morning simply wanting more technology. They require reliable products that are straightforward to install and help them get the job done as quickly and efficiently as possible. That’s the reminder we continue to give ourselves when looking at connected solutions. Technology should

only exist if it solves a genuine problem. LumiWave does that by simplifying emergency lighting compliance, while LumiSmart has been developed to make intelligent lighting control easier to specify, commission and manage. They’re different solutions, but both are built around making life easier for the installer and delivering a better experience for the end user. Keeping things straightforward As products and systems become more advanced, manufacturers have a responsibility to ensure they remain accessible to those expected to install them. The best product in the world won’t succeed if people don’t understand it or they believe it will be complicated to install. Electricians are busy and don’t have time to read lengthy manuals before getting started, which is why we’ve placed so much emphasis on making our products straightforward. That needs to be backed by clear installation guides, useful technical literature and knowledgeable support when required. Whether somebody is installing a straightforward lighting product or a connected solution such as LumiSmart or LumiWave, we want them to know support is available. That could mean technical advice, commissioning assistance or simply someone at the end of the phone to answer a question. Conﬁdence in the product is important, but conﬁdence in the support behind it matters just as much. Investing in the bigger picture The new product launches are probably the most visible part of what has been happening at Lumineux recently, but they’re only one element of a much bigger picture. We’ve continued to invest across the business, strengthening our product portfolio, expanding our sales and marketing teams, developing our technical capabilities and building the support our customers expect. From my perspective, I’ve wanted to bring a more proactive approach to marketing. That doesn’t mean marketing for marketing’s sake, but instead communicating consistently, sharing useful information and spending more time understanding what our customers need.

PROFESSIONAL ELECTRICIAN

That’s why you’ll have seen Lumineux investing more in PR, digital content and social media, while working more closely with trade publications and industry partners. We’re putting greater focus behind these activities because I believe they help us remain connected to the market and the people using our products. Alongside that, we’ll continue investing in new products, technologies and the people behind them. What comes next? We’ve got plenty planned over the next 12 months, both in terms of new products and how we support the market. With LumiSmart joining the portfolio, alongside the continued development of LumiWave and our core lighting ranges, we’ll continue broadening the solutions available to customers. The thinking behind them, however, won’t change. We’ll keep spending time with contractors, wholesalers and end users because those conversations help shape where we go next. The industry won’t stand still, and neither will we. Our job is to keep learning, improving and looking for ways to make a practical difference.

LIGHTING

Stamen Tasev, Country Manager UK & Ireland at Shelly, looks at the reasons why lighting is the retrofit market’s best kept secret.

LIGHT YEARS AHEAD

mart home technology has had a perception problem in the UK. For years it was associated with new builds, high budgets and a level of technical complexity that put off the majority of homeowners and the installers who serve them. Lighting, in particular, felt like something you planned from the ground up or didn't bother with at all. That perception is changing, and from where we sit, the retroﬁt lighting opportunity is one of the most exciting in the market right now.

The UK home is ready for this Britain's housing stock remains one of the oldest in Europe, with the vast majority of homes that will exist in 2040 already built today. The government's retroﬁt strategy continues to focus on upgrading existing homes rather than relying on new-build standards alone, recognising that improving the energy performance of the UK's ageing housing stock is essential to meeting Net-Zero targets. Lighting is where that question now has a compelling answer. Modern smart dimmer and switching devices are designed to work with the wiring already

in place, including the many older UK properties that lack a neutral wire at the switch. Installers can walk into a home and upgrade an entire floor of lighting in a day, using the existing switches and fittings, without touching a single ceiling rose or lifting a floorboard. The result for the homeowner looks and feels like a high-end system. The installation is clean, fast and profitable for the trade. What homeowners actually want The conversations we're having across the UK point consistently in the same direction. Homeowners want control – the ability to set the correct light for the right moment, whether that's a bright, energising start to the morning, a softer atmosphere in the evening, or lights that respond automatically when they leave a room. They want schedules that mean they never come home to a dark house and they want to stop worrying about whether they left something on. Energy is the other constant. The focus on household energy efficiency shows little sign of slowing. The latest ONS housing efficiency data shows that while the average efficiency of homes in England and Wales is improving, older

properties continue to lag behind newer housing stock, creating significant scope for retrofit technologies that can reduce unnecessary energy consumption. The installer advantage What's shifted most significantly in the last couple of years is installer confidence. Smart lighting used to require a specialist – someone with deep knowledge of a proprietary ecosystem, dedicated training and often a minimum project size that made smaller residential jobs unviable. That's no longer the case. The technology has become genuinely accessible, and the best solutions on the market today are designed with the installer in mind: quick to configure, reliable in the field, and backed by support that doesn't disappear after the sale. In the case of those installers who haven't yet made smart lighting a core part of their offering, the

timing has rarely been better. The demand is already there among their existing customers, the installation barrier has come down dramatically, and the margin opportunity, both on the initial ﬁt and on the ongoing relationship with a customer whose system can grow over time, is real. Where we're heading Lighting is rarely the end of the story. Once a homeowner experiences

responsive, automated light in their home, the appetite for extending that intelligence to heating, security and shading typically follows. This represents the beginning of a longer and more valuable customer relationship for installers, and for the smart home market as a whole, lighting is increasingly the front door. At Shelly, what drives us day-to-day is making that entry point as wide as possible – ensuring the technology is affordable, ﬂexible and straightforward enough that no installer feels locked out of the opportunity, and no homeowner feels it isn't for them. The UK retroﬁt market is vast, largely untouched, and ready. The industry just needs to meet it where it is. BROWSE THE FULL SHELLY RANGE OF PRODUCTS AND SOLUTIONS BY VISITING: WWW.RDR.LINK/ECB027

Jason Covell, Product Manager at Brackenheath, reveals how the brand is making outdoor lighting specification and installation simpler through a co-ordinated range that’s designed with electricians firmly in mind.

A BRIGHTER SPOT

rackenheath’s new iSpot collection combines uniﬁed installation, ﬂexible functionality, and installer-focused features across a complete family of outdoor luminaires.

Meeting the changing demands of outdoor lighting Homeowners increasingly expect outdoor lighting to do more than simply illuminate a space. Products must complement the appearance of the property, operate reliably throughout the year and provide practical features that improve security, convenience and energy efficiency. The new iSpot Outdoor Lighting collection from Brackenheath has been developed to meet these expectations while also making product selection and installation more straightforward for electrical contractors. One co-ordinated family of luminaires The collection brings together bulkheads, ﬂoodlights, lanterns, up-and-down lights and bollards within one co-ordinated outdoor-lighting family. Each product follows the same design, allowing installers to create a consistent appearance across entrances, pathways, driveways, gardens and other exterior areas. Traditionally, contractors may need to select products from several different ranges or manufacturers, with no guarantee that the ﬁnishes, designs, or functionality will complement one another. The iSpot

76 September 2026

collection provides a complete solution from a single established lighting brand, helping installers achieve a more uniformed and professional result across the property. Simplifying installation and future upgrades Selected products within the range have been developed around a unified installation. This can make future product changes and upgrades easier by reducing the need for significant alterations to existing fixing points or cable positions. For example, a homeowner may be able to replace a floodlight with a lantern or an up-and-down light using the same fixing positions. This provides greater flexibility both during the initial installation and for future upgrades. Flexible control options in a single product The iSpot bulkhead also combines four operating options within a single product. Configurable functions include PIR detection, photocell operation, PIR with dimmed standby lighting and manual override. Installers can therefore adapt the fitting to suit the property and application without needing to specify or buy several separate product variants. This flexibility can help wholesalers and contractors reduce stock complexity while giving homeowners greater control over how their outdoor lighting operates. The lighting can be configured to respond to movement, switch automatically according to ambient light levels, or maintain a reduced background output

before increasing to full brightness when activity is detected. Enhanced detection for improved security Selected PIR models provide a detection range of up to 10 metres and incorporate anti-creep coverage. This helps reduce the blind spot directly beneath a conventional motion sensor, improving detection when someone approaches close to the ﬁtting. Designed for excellent year-round outdoor performance Designed for exposed outdoor environments, the collection provides IP65 protection against dust and water ingress, including around the PIR sensor, together with an IK07 impact-resistance rating. This helps ensure reliable performance throughout the year in a wide range of exterior applications. Supported by decades of expertise Backed by more than 45 years of Brackenheath lighting experience, the iSpot collection combines contemporary design, installer-focused engineering, and ﬂexible control options within one co-ordinated range.

UNI-VERSAL APPEAL Keeping tools and lighting powered shouldn't complicate the job. Shyel Stark, Product Sourcing Director at Luceco Lighting, discusses a smarter approach to battery-compatible site lighting.

hilst cordless power tools have transformed the way tradespeople work, one challenge remains – managing multiple batteries, chargers and power sources across different equipment platforms. Recognising this issue, Luceco has developed its UniVolt range of inspection and work lights to provide a more flexible approach to portable site lighting. Designed around the needs of today’s installer, the range allows tradespeople to use the batteries they already own, delivering powerful, reliable illumination without the need to invest in additional battery platforms. It is compatible with many of the leading 18/20 V power tool battery brands, including Black & Decker, Bosch Pro, Dewalt, Makita, Milwaukee, Porter Cable and Stanley. Designed around the installer Whether carrying out inspections, working in confined spaces or installing equipment across larger sites, clear visibility helps professionals complete tasks with confidence. Luceco’s UniVolt range has been developed with these considerations in

78 September 2026

mind, combining high-output LED technology with practical features designed for professional use. By using batteries, it eliminates the need to wait for items to recharge, and the battery can be replaced immediately on-site, making better use of the equipment already available in the van or workshop. Installers invest heavily in their cordless tool platforms, so it makes sense that their lighting should work alongside those systems rather than create another battery requirement. UniVolt has been designed to provide a simple, practical solution that ﬁts seamlessly into the way tradespeople work. Whilst traditional rechargeable lighting products can experience a gradual reduction in brightness as battery power decreases, UniVolt models feature smart electronics designed to maintain stable illumination throughout the task. This consistent light output is a major benefit of the range and ensures installers have dependable visibility when accuracy is critical. Flexible lighting for every application Designed to meet the varied requirements of professional users, the UniVolt range includes a selection of portable lighting solutions:

I LIKE YOUR

ACCENT

hile you’ll be asked to install general lighting using downlights, pendants or panels for most domestic installations, accent lighting will add depth, mood and interest. This plus task lighting will transform a ﬂat lighting scheme into something with a real ‘wow’ factor. And it’s not difficult to do with a little bit of knowledge.

Do you know how to use accent lighting to provide that extra ‘wow’ factor? Anthony Martindale, Senior Product Manager at Collingwood Lighting, provides some tips so that you are seen as far more than “just an installer.” Creating layering of light A great lighting scheme uses layers of light to create the right atmosphere for a space. It combines general or ambient lighting with task and accent lighting to create a visually interesting whole. While task lighting will enable them to complete a task, whether that is working at a computer or preparing food, accent lighting will add interest to a room. Rather than simply make a room bright, you need to work with your customer to create a look that will impress them and visitors. It’s not just about adding more light but considering where to use it and what to leave in shade. A common mistake is to overdo a scheme, which will ruin what you and your customer are trying to create. Instead, think about creating bright focal areas, darker zones to add depth and soft background lighting. Where to use accent lighting When you walk into a room consider what stands out. Talk to your customer and ask them how they want a room to feel and what they want people to notice when they walk in.

Lighting design is all about contrast, so prioritise and pick two or three features that they want to highlight. Common examples include artwork, architectural details, shelving, textured walls, plants or cabinets. Top tips for accent lighting You want to see the effect of the lighting but not the source, so the lighting either needs to be hidden from view or directed at the object to avoid glare. For artwork and sculptures use adjustable spotlights or picture lights to direct light where it’s needed. A narrow beam angle will create drama. Think about using uplighters or downlighters to emphasise architectural details like exposed brick, textured walls, columns, or interesting ceiling designs. For an easy upgrade, which is simple to install and will add a touch of sophistication to any space, add LED strips to shelves, cabinets, wardrobes or even stairs. These offer a soft light and emphasis any linear features in a room. You can take this a step further by hiding LED strip, which offers a soft diffuse light that creates atmosphere for a

080_PE_SEPT26_Layout 1 30/07/2026 10:22 Page 81

sophisticated feel in any room. You can use it in ceiling coving, headboards or behind furniture. To emphasis texture, wall grazing is another useful trick to have up your sleeve. If your customer has a brick or stone wall, or even wooden panels, you can help emphasise this area by installing ﬁttings close to the wall. This creates light and shadow to emphasis texture. Another option is wall washing. Here you place spotlights a few feet away from the wall to create a soft even glow that will smooth out imperfections and make a room feel larger. Other factors to consider Your customer will need to control their accent lighting so recommend separate switching and/or dimming. If they have the budget, then more sophisticated control systems allow them to consider setting different lighting scenarios, depending on what mood they want to create in a room. Because you use accent lighting to emphasise features it’s worth considering the colour temperature of the lighting. For

warmer coloured features such as oranges or reds or for wood, a warmer correlated colour temperature (CCT) of 2700K or even 2200K will help make it glow. If you’re highlighting cooler colour temperatures such as blues, greens or white then recommend a higher CCT of 4000K to make it even more vibrant. And if you’re lighting artwork then the colour rendering index (CRI) is important. For most lighting, a CRI of more than 80 is ﬁne, but where you want a very accurate colour representation then choose a source that has a CRI of greater than 90.

Adding accent lighting in the right place is a simple way to improve your customer’s lighting. Using it in combination with ambient and task lighting will help produce sophisticated multi-layered effects. Ultimately, a few well-placed suggestions are likely to help you win more business with a higher value. BROWSE THE FULL COLLINGWOOD LIGHTING PRODUCT RANGE BY VISITING: WWW.RDR.LINK/ECB030

ONE IN A MILLI Small in size but big on options, the Ovia Inceptor Milli downlight goes under the spotlight as Reece Hardy puts it to the test.

without having to disturb the ﬁxed wiring. Space above the ceiling was restricted on parts of this installation, so the relatively shallow height of the LED unit was another advantage. The Milli also incorporates a rotatable twin insulation cover, allowing it to be safely installed beneath insulation while providing an additional 5 mm of clearance when adjusted.

hen you’re replacing existing downlights, you don’t always know exactly what you’re going to find until the old fittings come out. Limited ceiling voids, existing cabling and different lighting requirements can all make what should be a straightforward job that little bit more challenging. That’s why having a versatile replacement option can make life much easier. I recently had the opportunity to try the Ovia Inceptor Milli downlights on a domestic replacement installation, where the customer wanted to upgrade a number of older fittings without disturbing the existing ceiling or completely rewiring the lighting circuit.

Your flexible friend The first thing that appealed to me was the flexibility built into each fitting. The Inceptor Milli offers selectable 4 W or 6.4 W outputs alongside three selectable colour temperatures. This meant I could adjust the fittings to achieve the light level and appearance the customer wanted without having to carry or order different versions. The fittings are also IP65 rated, fire-rated and dimmable as standard, making them suitable for a wide range of locations, including kitchens and bathrooms. The versions supplied to me had white bezels, although alternative finishes are available if required. For this particular job, I was able to utilise the original cabling, with the supplied Flow push-fit connectors making the replacement process relatively straightforward. Each downlight comes

with a pre-wired male connector, along with a three-pole female push-ﬁt connector with loop. One thing I did notice is that space within the loop connector is fairly limited, so I’d recommend using 1 mm² cable maximum where possible. If you’re terminating three cables, they need to be threaded in carefully. The screwless terminals do have release mechanisms, however, which is useful if cables need to be repositioned. Two screws on top of the free socket connector then allow the cap to be securely locked in place. A feature I particularly liked was the plug-and-socket arrangement between the connector and the downlight itself. Once the wiring is connected, the lamp simply plugs into the socket. This means individual ﬁttings can easily be disconnected from the daisy chain for testing, maintenance or replacement

Versatile and easy to install From a safety perspective, the fittings are fire-rated for 30, 60 and 90-minute ceiling constructions and incorporate an intumescent strip designed to expand in the event of a fire and help seal the opening around the fitting. It’s also good to see some thought given to the product’s longer-term environmental impact. Ovia assesses the range using the CIBSE TM66 methodology, looking at factors including product construction, disassembly and the potential to recycle or refurbish individual materials. Overall, I found the Inceptor Milli to be a versatile and installer-friendly downlight. The selectable wattage and colour temperature, compact dimensions and plug-in connection system are all useful features, particularly on replacement jobs where flexibility can make the difference between a straightforward installation and an unnecessarily complicated one.

Steve Hewish, Senior Electrician at Unique Group (SW), takes the ROBUS VEGAS LED strip range for a spin to see whether its extensive choice of options can hit the jackpot.

A SAFE BET

ED strip has become an increasingly useful option for electricians, whether you’re lighting underneath kitchen cabinets, around bathroom mirrors, outside spaces or creating feature lighting in commercial and hospitality settings. The key, however, is having a system that gives you enough flexibility to adapt to different jobs. That’s where the ROBUS VEGAS range immediately caught my attention. There’s a broad choice of strip available, including single colour, tuneable white, RGB and RGBW options, with IP20 and IP67 versions covering both indoor and outdoor applications. The strip I was sent to test was used to replace the lighting in a conservatory and provide illumination above a hot tub, so the IP-rated strip and drivers were ideal for the job. The IP-rated drivers are particularly useful for outside installations or areas such as poorly sealed or insulated conservatories, where moisture can potentially be an issue.

84 September 2026

Once installed, the ﬁnished result looked really effective. The LED strip provided a clean, even spread of light around the conservatory, while the lighting above the hot tub helped create more of a feature of the area rather than simply providing functional illumination. It completely changed the feel of the space after dark and, most importantly, the customer was pleased with the end result. For me, it was a good example of how LED strip can transform an area without the lighting itself becoming too intrusive. Since completing the installation, I’ve also had the opportunity to try the non-IP-rated drivers, which are well suited to more conventional indoor domestic and commercial applications. Lots of options available One of the biggest strengths of the VEGAS range is the sheer number of options available. There are multiple colour temperatures, as well as colour-changing strips, while different controller options allow the lighting to be operated manually, remotely or through Wi-Fi, depending on the requirements of the installation. There’s also a good selection of LED drivers, ranging from 15 W right up to 320 W, so you can select the appropriate power supply to match the length of strip being installed. The 24 V system also allows for longer runs while helping to reduce the risk of dimming and potential unit failure. Installation is made easier by the availability of clip connector packs, while the strip can be cut every three LEDs and reconnected as required. ROBUS also offers a cut-to-length service, which could

PROFESSIONAL ELECTRICIAN

be particularly useful if you want strips prepared to specific lengths before arriving on-site. Another big plus for me is the choice of profiles available. Depending on the application, you can opt for angled, recessed or walk-over profiles, with accessories including corners and T-pieces helping to create a much neater, more professional finish. From an installer’s point of view, the warranty is worth mentioning too. The range comes with a three-year warranty, including two years of on-site cover, meaning that if a ROBUS product fails during that period, it can be replaced without cost to the installer. Overall, I found the ROBUS VEGAS range to be a very versatile LED strip solution. The combination of different strips, drivers, controllers, profiles and accessories means you can adapt the system to suit almost any installation. Having now used it on a real job and seen the finished effect for myself, I’d certainly consider specifying it again. BROWSE THE ROBUS VEGAS LED STRIP RANGE AT: WWW.RDR.LINK/ECB033

CONTROL, ALT, DELIGHT Carrying every possible switch isn't always the smartest solution. Paul Foulkes, Country Manager at Theben, explores a more flexible approach that can keep future upgrade options open.

pen the average electrician's van and you'll probably find a collection of lighting accessories – two-way switches, intermediate switches, rotary dimmers, pneumatic timers and multiple finishes. Yet the one you need is often still sitting on the wholesaler's shelf. There is another approach, however. By standardising on retractive switches and selecting the appropriate control device behind them, installers can tackle a wider range of lighting applications without carrying every possible switch. Customers benefit from a consistent finish, while electricians gain greater flexibility when requirements change.

One switch, multiple functions From the customer's perspective, a retractive switch is simple – press it and something happens. What happens depends on the control device behind the switch. That could be: ● Basic on/off switching ● Dimming ● App-conﬁgured dimming ● Timed staircase lighting The visible accessory remains the same throughout the property, while a compact device provides the required function. This creates a consistent appearance while allowing installers to carry fewer switch types and simply select the control device to suit the application. Simplifying multi-way switching A traditional staircase circuit uses two-way and intermediate switches connected with 3-core-and-earth cable. An electronic latching relay such as the Theben OKTO

86 September 2026

540 BN offers another option, allowing multiple retractive switches to control the same lighting circuit. Because the switches send only a control signal, standard twin-and-earth cable can often be used instead of 3-core-and-earth. With the latter costing around 25% more, savings can quickly add up on larger projects. It also gives installers greater flexibility when designing or extending the circuit. When the customer changes their mind A customer may initially ask for basic switching before later deciding they want dimming. With retractive switches already installed, the visible controls remain the same while the control device is upgraded. The DIMAX 540 plus B provides push-button dimming without requiring a neutral conductor at the device. A short press switches the lights on or off, while pressing and holding adjusts the light level. For customers wanting more functionality, the DIMAX 540 APP B adds app-based commissioning with features including scenes, groups and astronomical switching, while the wall switch itself remains unchanged. A smarter staircase timer Timed staircase lighting can also benefit from the same approach. The ELPA 540 APP BN can be installed in a suitable flush-mounted box and operated from switches or retractive push-buttons. Lighting stays on for the programmed period before switching off automatically, with timing and additional functions configured through an App. Features such as switch-off pre-warning and extendable lighting periods make it well suited to apartment buildings, communal areas and retrofit projects.

PROFESSIONAL ELECTRICIAN

Flexibility built in Not every lighting circuit needs electronic control, but where there are multiple switching points or future upgrades are likely, retractive switches keep those options open. The same approach supports: ● On/off control with the OKTO 540 BN ● Push-button dimming with the DIMAX 540 plus B ● App-conﬁgured dimming with the DIMAX 540 APP B ● Timed lighting with the ELPA 540 APP BN As with any lighting installation, device loading, LED compatibility, enclosure space and cable arrangements should be checked alongside manufacturer instructions and BS 7671. The result is a simpler, more ﬂexible installation, with fewer switch types in the van, less specialist cable on-site and more options when the brief changes.

In this article the team at Rako Controls share details about how innovative use of lighting controls has helped transform a compact Brighton courtyard into a private urban oasis.

COURT APPEAL

n city homes where outdoor space is often limited, a courtyard can easily become a place that’s viewed more than it is used. This project set out to change that, transforming a compact urban garden into a luxurious retreat that could be enjoyed long after sunset. The client wanted more than practical exterior lighting – a space that could feel calm and intimate on a quiet evening, become more vibrant when entertaining, and remain closely connected to the character of the home.

With its Moroccan-inspired detailing, decorative screens, textured surfaces, planting and water feature, the garden already possessed a strong identity. The role of the lighting was to reveal these elements at night, enhancing the character of the space without overwhelming it. Rather than illuminating everything equally, the design focused attention where it mattered most. Planting, architectural details, patterned screens, textured tiles and the main focal point were all carefully highlighted, using layers of light to create contrast, dimension and visual interest. The result is a space that changes dramatically once daylight fades. Instead of disappearing into darkness, it takes on an entirely different character.

Creating atmosphere through control A Rako lighting control system was speciﬁed to provide complete ﬂexibility while keeping operation simple. Rather than relying on multiple switches or individual circuits, the client can adjust the entire garden with a single touch. Several lighting scenes were created to suit different moments throughout the evening, from low-level, relaxed settings

88 September 2026

to brighter scenes for entertaining. This allows the space to respond naturally to how it is being used while keeping the technology intuitive. For the client, the experience is effortless. There’s no need to think in terms of circuits, zones or switching. Instead, they simply choose how they want the space to feel. This was particularly important in a compact courtyard, where every detail influences the overall experience. A single fitting set too brightly can dominate the garden, while a balanced scene can transform the entire environment. Pattern, shadow and texture One of the defining qualities of the garden is its use of pattern. Decorative screens, tiled surfaces and architectural detailing contribute to its Moroccan-inspired character, creating a sense of privacy, enclosure and escape. At night, these details become part of the experience. Light washes textured

088_PE_SEPT26_Layout 1 30/07/2026 10:54 Page 89

walls, catches perforated screens and produces shifting shadows that add rhythm and visual richness. The result is not just illumination, but a layered and immersive environment. Warm colour temperatures were used to complement the earthy palette, from the terracotta walls and textured tiles to the natural materials and planting. Against the evening sky, this warmth creates a soft and welcoming glow that makes the garden feel sheltered and inviting. The scheme deliberately avoids over-lighting. Certain areas are allowed to recede into shadow while important features are selectively illuminated. This restraint adds dimension and prevents the space from feeling ﬂat or overly bright.

helping the garden feel layered despite its compact footprint. This balance between planting, architecture and light creates a strong sense of cohesion. Every element has a purpose, yet nothing feels overworked.

An outdoor room Although modest in size, the courtyard was designed to feel like an outdoor room. The seating area, patterned floor tiles, warm wall finishes and enclosed layout create an environment that feels intimate and cocooning rather than exposed. Lighting reinforces this sense of enclosure, bringing the comfort typically associated with interior spaces into the garden and helping it feel like a natural extension of the home. Through scene-based control, the client can move easily between different settings. Softer scenes create a quiet retreat for evenings outdoors, while brighter arrangements make the space welcoming for guests. A feature wall brought to life The focal point of the project is the Moroccan tiled feature wall with its integrated water fountain. During the day it adds colour, texture and personality, but after sunset it becomes the visual centrepiece of the garden. A bespoke lighting arrangement was developed around this feature, with each fitting positioned to accentuate the texture, colour and craftsmanship of the tiles. Carefully directed uplighting reveals details that are not fully appreciated in daylight. The water feature introduces another sensory element. Subtle illumination enhances the reflective qualities of the green tiles, while the movement of water brings a gentle sense of life to the space. Light, texture and reflection work together to create a calm and engaging focal point.

The solution Rako RMT500 and RMS800 modules were used to provide reliable control of both the lighting and water features. The system was selected for its ﬂexibility, ease of programming and dependable scene-based operation. Behind the scenes, sophisticated programming delivers a seamless user experience. The technology remains unobtrusive, allowing the lighting, materials, planting and water features to take centre stage.

The fountain was also incorporated into the lighting scenes, allowing water and illumination to operate as a single design element. Whether the space is used for entertaining, relaxation or a quiet late evening outdoors, the feature wall remains at the heart of the experience. Planting after dark Planting plays an important role in the garden’s evening character. Uplighting to the trees and specimen plants introduces height and structure, drawing the eye through the space and softening the surrounding architecture. The olive tree, palms and low-level planting become almost sculptural at night. Their forms, textures and shadows introduce movement and visual interest,

A luxurious outdoor experience The ﬁnished garden demonstrates the impact that intelligent lighting can have on smaller exterior spaces.

HEARD

Following the launch of two new business tools for trade professionals, we put the questions to Ben Dyer, Founder & CEO of Powered Now, to find out how AI-powered tools are helping electricians build stronger businesses and customer relationships. What problem is Powered Now’s ‘AI Receptionist’ and 'Here Is My Work' trying to solve for today's electrical contractor?

Most electricians are effectively running two businesses. There's the electrical work, the skilled, physical stuff they trained for. And then there's the business of finding customers and keeping them coming back. The second of these is where most electricians are losing, not because they're bad at their trade, but because they have no system for it. ‘Here Is My Work’ fixes the visibility problem. A professional website, a place to showcase completed jobs with photos, and a system to collect genuine customer reviews, built specifically for electricians and designed to run with minimal effort. It connects directly to Powered Now's AI Receptionist, so when an enquiry comes in and the electrician is on-site, the call gets answered, the details get taken, and the job gets booked. The electrician finds out when they come off-site, ensuring the lead doesn’t go cold.

Why has showcasing completed work become so important in winning electrical contracts?

The way customers choose electricians has changed. A referral used to be enough. Now it's the starting point. The customer gets the recommendation, searches online, looks at the website and reviews, and decides, all before picking up the phone.

Photos matter because electrical work is invisible once it's done. A neatly installed consumer unit or EV charger signals professionalism to a customer who may not understand the technical details but can see that the work looks right. ‘Here Is My Work’ gives electricians a structured way to build that evidence over time. Every completed job is a photo, a review request, and a stronger proﬁle. After a few months, that proﬁle is working harder than any advert they could run. Many electricians are already busy enough on the tools. How have you designed the platform to minimise the amount of admin involved?

Simple answer: if it takes too long, it won't get used. ‘Here Is My Work’ works from a phone so uploading a job photo takes thirty seconds. The website is built from information you already have with review requests sent out automatically, so you don’t need to remember to ask. On the operational side, Powered

“Happy customers will often intend to leave a review and then forget. Unhappy ones don’t.” Now handles quotes, invoices, scheduling and certificates in one App. The AI Receptionist then ties it together – when a call comes in while the electrician is on-site, it answers, captures the lead, and books the job. By the time they finish the current job, the next one is already in the diary. The platform places a strong emphasis on helping users own their customer reviews. Why is this becoming increasingly important?

Because most electricians are letting their reputation happen by accident. Happy customers will often intend to leave a review and then forget. Unhappy ones don't. The result is an online reputation that reﬂects the minority of experiences rather than the quality of the work overall. ‘Here Is My Work’ makes review collection automatic. Every completed job triggers a request. Over time those reviews become one of the most powerful things working in the electrician's favour, driving more enquiries, which the AI Receptionist captures, before Powered Now converts into booked jobs. There's a longer-term point too. Reviews are increasingly how search engines and AI tools decide which businesses appear when someone searches locally. Building that record now is an investment that compounds. Can you share any early feedback or success stories from electricians who have already started using ‘Here Is My Work’?

Robert Brown of RB Electrical Services put it better than we could: “Powered Now AI Receptionist has answered six calls so far in a few days

92 September 2026

and four of them ended up booking jobs. That’s a 66% conversion straight to a booked job.”

That's the point in a number. The calls were already coming in. The leads were already there. What was missing was a reliable way to capture them when Robert was on-site doing his job. The AI Receptionist handled the calls, booked the jobs, and Robert came off-site to ﬁnd his week already ﬁlling up.

I’d recommend three things, in order of impact:

Looking ahead, how do you see AI changing the way electricians promote and grow their businesses?

It's already changing. The question is who's paying attention? The immediate impact is on lead capture. The AI Receptionist answers calls when an electrician is on-site, takes details, and books jobs. For a sole trader losing enquiries every week to an unanswered phone, that's not a small improvement, it changes how the whole business operates. The connection to ‘Here Is My Work’ is straightforward. A stronger online proﬁle generates more inbound calls. The AI Receptionist makes sure those calls convert rather than go cold. More leads, none of them missed.

PROFESSIONAL ELECTRICIAN

What advice would you give to an electrician who has never really promoted their work online before?

1. Get your ‘Here Is My Work’ profile live. It doesn't need to be perfect – a description of what you do, your CPS registration, and a handful of job photos is enough to start. Add to it after every job. 2. Collect reviews systematically. Send every customer a direct link after the job. A text works better than asking in person. Ten recent reviews will win more work than any advert. 3. Make sure every enquiry gets answered. Powered Now’s AI Receptionist handles calls when you're on-site so no lead goes unanswered. Most electricians are losing more work to an unanswered phone than they realise. GET MORE DETAILS ON POWERED NOW’S HERE IS MY WORK AND AI RECEPTIONIST OFFERINGS BY VISITING: WWW.RDR.LINK/ECB037

THE CURRENT STATE OF AFFAIRS Experienced professional, Bob Preston, looks at the risks posed by diverted neutral current (DNC) and describes how Tradefox’s latest training simulator is helping electricians prepare for the hidden dangers of PME networks.

The outer layer of the skin, the stratum corneum, is often described as a protective shield. In reality, it behaves more like a thin, unreliable film that can change from moment-to-moment. Moisture softens it, pressure flattens it, while sweat ducts and hair follicles provide conductive pathways. Even a small amount of hydration can significantly reduce its effectiveness as a protective barrier.

y way of introduction, I’m a MEICA engineer with 28 years’ experience in the electrical industry, having worked in every role from sweeping the ﬂoor to leading PMO teams. I’ve also contributed to the development of the latest City & Guilds 2366 Diploma, helping to shape the training that will guide the next generation of electricians. I now work with Tradefox, the company that pioneered digital safe isolation simulations and who PE readers will be familiar with thanks to the efforts of Founder, James Cornet. Having recognised the risks associated with failures on PME networks, the Tradefox team is back with a cutting-edge diverted neutral current (DNC) test simulator. Potentially dangerous assumption The original simulator proved incredibly effective at teaching engineers how to safely isolate a circuit from the primary supply. However, it was based on a potentially dangerous underlying assumption: once the main switch is off, the danger has gone. It didn’t account for the external threat posed by Protective Multiple Earthing (PME) and Combined Neutral and Earth (CNE) networks. In a broken neutral scenario on a PME network, an installation’s earthing can become a return path for neighbouring properties. Standard safe isolation procedures, such as switching off the local main switch, do nothing to isolate this imported danger. When I began developing the DNC simulator, I carried out extensive research, starting with biophysics.

94 September 2026

Human skin has long been treated as the industry’s quiet safety net – a built-in resistor that supposedly shields us from low-voltage contact. For decades, electricians and gas engineers have worked on the assumption that if a touch voltage sits below familiar thresholds, the danger is low. Modern research paints a very different picture. Skin is a fragile and inconsistent barrier, particularly under conditions we encounter every day – damp hands, sweat, pressure, large contact areas and cold metal surfaces. Combine these biological realities with the electrical behaviour of modern UK distribution systems and the industry faces an important truth: low voltage doesn’t necessarily mean low risk.

PROFESSIONAL ELECTRICIAN

Well documented effects Voltage can also actively break it down. When an electric field reaches the skin, lipids shift, water is drawn into the membrane, nanopores form and conductivity increases. These effects are well documented in biophysics. Similar mechanisms are used in medical electroporation and transdermal drug delivery. During accidental electrical contact, applied voltage can make the skin more permeable, hydrated and conductive. Once the outer layer gives way, deeper tissues – the viable epidermis and dermis – offer significantly less resistance because they’re hydrated and electrolyte-rich. That helps explain the dramatic reductions in total body impedance identified in IEC 60479-1 under certain conditions. Damp hands, large contact areas or firm pressure can push impedance down considerably. At sufficiently low impedance, even relatively small touch voltages may produce currents capable of causing serious physiological effects, including loss of muscular control, respiratory interference and an increased risk of ventricular fibrillation. The conditions that contribute to this risk are commonplace: leaning against a radiator, gripping a tap, touching a boiler

094_PE_SEPT26_Layout 1 30/07/2026 11:10 Page 95

casing, holding a metal tool with sweaty hands or standing barefoot on a damp floor. Everyday behaviour can create circumstances in which skin resistance is reduced and the body becomes more vulnerable. That vulnerability is particularly relevant because of the scale of CNE cable installed across the UK. The country has an extensive PME/CNE infrastructure, supplying millions of homes, businesses, farms and industrial sites. This creates a potential vulnerability – if the neutral is compromised, bonded metal components within an installation can rise in voltage and carry diverted neutral current. The danger extends beyond electric shock. Ignition risk is equally important and can easily be overlooked. Voltage alone doesn’t determine whether a spark is possible; the energy available and the current flowing through the path must also be considered. Bonded pipework can carry diverted neutral current without presenting a large voltage difference. Equipotential bonding may minimise potential differences, but it doesn’t necessarily prevent current from flowing. If a clamp is loosened or a pipe

carrying current is cut, interrupting that path can release energy and potentially create a spark. For this reason, current measurement has become an essential part of identifying the risk. Voltage pens and non-contact testers cannot detect diverted neutral current because they indicate electrical potential rather than the current flowing through a conductor. Taking foreseeable hazards into account A pipe sitting at a relatively low voltage may initially appear harmless, but current flowing through it could still present a hazard if the path is interrupted. Measuring current can help establish whether bonded metalwork forms part of an active return path, whether a neutral fault may be present and whether additional precautions are required before work begins. The legal framework also expects engineers to take foreseeable hazards into account. Health and safety legislation requires risks to be identified and appropriately managed, while electrical regulations seek to prevent unexpected energisation and equipment becoming live during work.

Gas safety requirements similarly demand that danger is prevented during activities such as purging and isolation. Relying solely on voltage testing may therefore fail to provide the complete picture where diverted neutral current is concerned. The combined evidence from biophysics, IEC 60479-1 and the behaviour of modern PME networks leads to an important conclusion: relatively low voltage rises on bonded metalwork can still be associated with currents capable of presenting a risk to people, property and livestock. That is why, through my work with Tradefox, I’ve been involved in developing a new simulator that explicitly models the complex failures associated with PME networks – scenarios that the original safe isolation simulator was never designed to address. Along with this, we are launching an electrical safety campaign to raise awareness about the dangers of PEN faults. The aim of this is to give electricians and engineers the opportunity to experience these conditions in a safe, controlled environment and understand why established assumptions may no longer be enough. The modern electrical landscape requires safety practices and training to evolve alongside it. We need to measure current as well as voltage, consider available energy rather than potential alone, and recognise that a low voltage reading does not automatically equal a low-risk situation. The physics has always been there. Our understanding, training and working practices now need to catch up. FIND OUT MORE ABOUT TRADEFOX AND ITS RANGE OF TRAINING SIMULATORS AT: WWW.RDR.LINK/ECB038

KNOWING WATT’S WHAT From instant calculations to CPD records, PE chats with Gary Lince, Director of Pro Certs Software, about the features electricians are relying on every day. For readers who are discovering the Electrical Tools & Reference App for the ﬁrst time, can you give us an overview of what it offers and explain why you originally developed it?

The Electrical Tools & Reference App provides instant access to the most commonly referenced tables such as cable rating tables and installation reference methods. In addition to the tables and charts, the electrical calculators offer instant calculations on the go, reducing the immediate need to reference the technical books or memorise complex calculation formulas. The App brings together a wide range of calculators, reference tables, technical documents and forms in one place. Which features do you ﬁnd electricians rely on most during a typical working day, and how can they help save time on-site?

The most used section of the Electrical Tools & Reference App is the Max Zs Values and Cable Calculator. The Max Zs values is a quick look-up tool for fuses, RCBOs and MCBs, while also included are some manufacture MCCB Zs tables which provides the information you need, when you really need it.

This is highly utilised by electricians conducting electrical inspections as the information is available instantly and you always have it in your pocket, which saves time on manual calculations and referencing the technical books and guides. Accuracy is vital when carrying out electrical calculations and referencing the Wiring Regulations. How do you ensure that the calculators, technical data and reference information within the App remain reliable, up-to-date and easy to use?

The Electrical Tools & Reference App is hand-crafted by experienced engineers, with all the calculations manually written and extensively tested. All reference tables are cross-referenced with the relevant standards. When an update to a standard is published, we manually check what has changed and apply the relevant changes to the App. One of the features within the App's Electrical Forms section is the ability to create and store Continuing Professional Development (CPD) Records. Why did you decide to include this functionality, and how can it help electricians demonstrate their ongoing competence and keep their professional records organised?

As the requirement for recording CPD activities has grown, the recording and storing of all the CPD material you’ve consumed

becomes very cumbersome. You always have your phone on you, so as soon as you complete a CPD activity you can very quickly record it on your phone ready to generate a PDF record to show your CPS provider assessor, when required. Looking ahead, what can users expect from future developments, and how do you use customer feedback to shape the direction of the App?

We recently published an update to include a user log-in so we can facilitate data syncing across multiple devices. Currently, the Electrical Tools & Reference App is in the process of being completely rebuilt from the ground up, utilising new technologies and frameworks which will ensure the longevity and maintainability going forward. New features will include an AI assistant amongst many others, which haven’t been made public yet. We welcome and act all on feedback we receive, and we encourage new feature requests. Users can contact us directly from within the App or via our website. GET MORE DETAILS ON THE PRO CERTS SOFTWARE ELECTRICAL TOOLS & REFERENCE APP BY VISITING: WWW.RDR.LINK/ECB039

THE ANSWER TO

MISSED CALLS Dru McPherson, Founder of Whoza AI, explains why the call you didn’t hear is the job you didn’t get.

magine you’re in a loft. It’s thirty degrees up there. You have one hand on a cable and the other on a torch, and your phone is ringing in your jacket pocket, downstairs, in the hall. That’s not necessarily a discipline problem, but a physics problem instead. Any article that tells an electrician to “prioritise responsiveness” without acknowledging that has already lost you. A recent survey of more than 220 tradespeople (source: Fix Radio) found that 34% believed they’d lost work because they couldn’t answer the phone. Six in ten said they struggled to answer while working. Nobody in that survey was being lazy, they were simply up a ladder.

“Most trade voicemail is a recording of an individual who sounds annoyed to have been called.” 98 September 2026

So the question is not whether you should answer more calls. Obviously you should. The question is what to actually do about it – and the honest answer is that the options are cheaper and more varied than some would like you to know. Start with the free stuff, because most people never do Fix your voicemail message. Most trade voicemail is a recording of an individual who sounds annoyed to have been called. “You've reached Dave, leave a message.” Nobody leaves a message for that person.

It gives them a route if it’s urgent – a text number, a WhatsApp – anything that doesn’t require you to be free at that exact moment. Set up a divert. If there’s anyone – a partner, a family member, a mate who may be off the tools – who can take calls during the day, a divert costs you nothing and has the potential to catch more work than any App. The paid options, and what they don't always tell you Traditional answering services put a human on your phone. They work. They’re priced accordingly, and the thing to interrogate is what happens after the call. Most take a message and promise a call-back. AI answering is the newer option, and it’s where I have a commercial interest – so treat what follows with appropriate suspicion.

Let’s look at what it’s genuinely capable of ﬁrst: a) it answers on the ﬁrst ring, at three in the morning, on a bank holiday, b) it tells an emergency from a quote request, c) it never gets bored. Where it still falls over, and you deserve to hear this from someone who sells it, is that it can mishear postcodes. That’s precisely the thing you cannot afford to get wrong, so any system worth buying should capture numbers by keypad as a backup. It can also struggle with a strong accent on a windy site, with some customers hanging up the moment they realise it’s a machine. Not many. But some. The one question that actually matters Whatever you’re being sold, human or machine, ask this: Does it book the job, or does it take a message and promise a call-back?

TRACKING PROGRESS

PE talks to Ben Baker, Electrician and Inventor of the CPD Progress Tracker App, to find out how feedback from users is shaping the platform and what new features could be on the horizon. Since we last featured the CPD Progress Tracker App, what feedback have you received from electricians using it in the real world, and has any of that inﬂuenced future development?

The most encouraging feedback has been that the App is achieving what I originally designed it to do in terms of making CPD recording straightforward, quick and useful. I recently received my ﬁrst public review from an iOS user who had previously been using folders and Excel spreadsheets to record CPD. He explained that the old process had become difficult to manage and was mainly useful only to himself, whereas the App made it much easier to record training promptly after completing it. He is now transferring his existing CPD records into the App.

That feedback was particularly valuable because it confirmed that simplicity is one of the App’s main strengths. CPD itself isn’t necessarily difficult, but recording it properly, locating supporting evidence and presenting it later can become fragmented and time-consuming. My intention has always been to remove as much of that friction as possible. The reviewer also suggested adding CSV import functionality so existing spreadsheet records could be transferred more easily. It’s something I’m now seriously considering for a future update. I’m currently developing another App that imports and analyses CSV files, so the experience gained from that project should help me assess how the functionality could be introduced reliably. More broadly, the feedback has reinforced the direction of future development. I want to add greater flexibility and profession-specific features without losing the quick and straightforward recording process users value. Any new feature should make CPD management easier rather than adding unnecessary complexity. You’ve mentioned plans to introduce custom fields for profession-specific CPD requirements as an optional add-on. How would this work and what additional flexibility could it offer?

The current version is intentionally simple, allowing users to record an activity, date, time spent, supporting details and evidence without working through an unnecessarily complicated process. The planned optional upgrade would retain that straightforward core while enabling users to tailor the App more closely to the requirements of their trade, profession or membership body.

100 September 2026

PROFESSIONAL ELECTRICIAN

Different organisations ask for CPD to be recorded in different ways. Some may require categories of learning, reflective comments, learning outcomes or evidence of how an activity has influenced working practices. Others may use points, credits or annual targets rather than time alone. Custom fields would allow users to record the information relevant to them without forcing everyone to complete fields they don’t need. An electrician, for example, might categorise activities under technical knowledge, health and safety, regulations, inspection and testing or business development. I’m also considering profession-specific templates that could automatically suggest suitable fields and tracking methods when a user sets up the App. These could

100_PE_SEPT26_Layout 1 30/07/2026 11:35 Page 101

then be adjusted to suit the individual rather than imposing one ﬁxed format. Users who simply need a quick and reliable CPD record could continue using the core App as it is, while those with more detailed professional or audit requirements could choose a one-time upgrade offering custom ﬁelds, points or credits, advanced targets and more detailed exports. Having developed the App from first-hand experience of the frustrations surrounding CPD logging, where do you see it evolving over the next 12 months?

I’d like CPD Progress Tracker to become more flexible and useful to a wider range of users while preserving the simplicity that was central to the original idea. Profession-specific custom fields and templates are likely to form an important part of that development, allowing users to tailor the App to their trade, professional body or employer. This could include points, credits, categories, learning outcomes and more detailed targets where required. I’m also considering CSV import functionality following the suggestion in the App’s first public review. This could

“The App has already evolved beyond its original version through multiple new features...” make it much easier for users to transfer existing CPD records from spreadsheets rather than manually entering several years of information. Other potential developments include more ﬂexible exports, improved progress and target reporting, and further reﬁnements to how users search, organise and retrieve records and supporting evidence. We aim to make the App increasingly useful when preparing for audits, appraisals, professional reviews or membership renewals. The App has already evolved beyond its original version through features including improved search, support for multiple professions and multilingual functionality. I expect future development to follow the same principle: listen to how people are using it, identify where unnecessary effort still exists and introduce improvements that remove that effort without making the App complicated.

Ultimately, I want CPD Progress Tracker to remain a straightforward everyday tool while becoming capable of supporting more detailed professional requirements when users need it. FIND OUT MORE AND PURCHASE THE CPD PROGRESS TRACKER APP BY VISITING: WWW.RDR.LINK/ECB041

IF THE APP FITS Electrical Qualified Supervisor and dynamik.app inventor, George Dobre, reveals why his own frustrations with disconnected software inspired him to build an allin-one business platform specifically for electrical contractors.

ike many people in the electrical trade, I know what it’s like to finish a full day’s work only to realise there are still hours of paperwork waiting for you. I was running my business using a mixture of spreadsheets, paper certificates and separate Apps for invoicing, accounting and certification, alongside a phone full of job photos I could never find when needed. The biggest frustration wasn’t simply paying for several subscriptions; it was that none of the systems talked to each other. I’d complete a certificate in one place, raise an invoice somewhere else, then enter the same customer and job information again into the accounts. Every extra step took time and created another opportunity for something to be missed. So, in my quest to find a better way, I decide to create dynamik.app. Joining the dots The idea behind dynamik.app is simple: to give electrical contractors one place to manage the whole operation, from the first quote through to the final certificate and payment. Certification, scheduling, estimates, invoicing, accounting, CIS, payroll and client communication all sit within one connected platform. A quote becomes a job, the job carries its certificates, completed work feeds into the invoice, and the invoice flows through to the accounts. Customer details only need to be entered once and will follow the job throughout. In terms of efficiency and productivity, this means less double-entry, fewer missed invoices and a clearer picture of what’s happening across the business. Certification on-site As an electrician myself, certification was always going to sit at the heart of the platform. dynamik.app supports 18 recognised certificate types, including EICs, EICRs and Minor Works, alongside certificates for EV charging, solar PV, fire alarms, emergency lighting and PAT testing.

Engineers can complete certificates from a phone or tablet on-site, working through the information board-by-board and circuit-by-circuit. Observations are colour-coded by classification, while completed certificates are stored against the relevant job and client. A helping hand from AI I’m in the unusual position of being both an electrician and a programmer, so I understand the job from both sides. That has influenced how we use AI within dynamik.app. Rather than adding AI for the sake of it, I wanted to apply it to repetitive jobs that genuinely consume contractors’ time. For example, users can describe a job in plain English or upload a site floor plan to generate a draft risk assessment covering hazards, risk levels, control measures and PPE requirements. The qualified person remains in control, reviewing and approving everything before it’s issued. There’s also Volt, the platform’s built-in assistant. You can ask questions such as “Which invoices are overdue?” or “How many jobs have we got booked this week?” and receive answers based on live information within your account. Most importantly, I want the platform to keep evolving around the people using it. If contractors tell us there’s a feature, certificate or workflow that would make their working lives easier, we want to hear about it. After all, the best tools for the trade should be shaped by the people actually using them. To celebrate the App’s launch, George has kindly set up an exclusive offer for PE readers, so that anyone registering using the code PE2026 will be eligible for six months of free access to the platform.

BUG What gaps in the market or day-to-day challenges faced by electricians and installers led C.K Tools to develop Cable Bug?

Electrical installations are constantly evolving, and so too are the materials electricians work with. One of the biggest changes in recent years has been the increasing use of Low Smoke Zero Halogen (LSOH) cable, particularly across commercial buildings, schools, hospitals and other public environments where fire safety is a key consideration. While LSOH cable offers important safety benefits, it also presents a practical challenge on-site. When compared to traditional PVC cable, it's tougher to strip cleanly and can become even more difficult to work with in colder conditions. As cable specifications have evolved, we recognised that electricians needed a purpose-built solution for preparing modern flat cable quickly, safely and consistently. Cable Bug was developed in direct response. Rather than trying to reinvent the toolbox, we focused on improving one of the most repetitive tasks electricians perform every day. Saving just a few seconds on each cable might seem insignificant, but over the course of a working day, or an entire career, it adds up to a significant improvement in productivity.

104 September 2026

We quiz Tim McCann, Trade Marketing & Communications Manager at C.K Tools, about the thinking, development and feedback that has led to the launch of Cable Bug.

Which speciﬁc tasks or installation scenarios was Cable Bug designed to make easier, quicker or more accurate for electricians working on-site?

Cable Bug is designed for the everyday task of preparing ﬂat cable, but it really comes into its own when working with modern LSOH cable. With more projects specifying LSOH cable, electricians increasingly need a tool that can cope with its tougher outer sheath while still delivering a clean, controlled strip. That becomes particularly valuable during colder weather, when the material can become even less forgiving.

“Rather than trying to reinvent the toobox, we focused on improving one of the most repetitive tasks electricians perform every day.”

PROFESSIONAL ELECTRICIAN

Whether installing lighting, power circuits, consumer units or containment systems, Cable Bug helps prepare cable quickly and consistently while reducing the risk of damaging the insulation beneath the outer sheath. By removing much of the guesswork from cable preparation, it helps maintain workflow, improve consistency and allows installers to move confidently from one task to the next. For those who may be looking to get the most out of their cable preparation, pairing Cable Bug with our Redline VDE combi cutters rounds out the process, giving installers the ultimate stripping solution – from initial cut through to a clean, finished strip. Can you talk us through any stand-out design features or innovations, and explain the advantages they offer compared to more traditional cable stripping methods?

The biggest innovation behind Cable Bug is its simplicity. It wasn't developed because electricians needed another

104_PE_SEPT26_Layout 1 30/07/2026 11:45 Page 105

cable stripper, but instead because the cables themselves are changing. As LSOH becomes more widely speciﬁed, installers need tools that are purpose-built to work with these tougher materials while delivering the same speed and consistency they've always expected. Rather than relying on a utility knife and the user's judgement, Cable Bug provides a controlled, repeatable stripping action that's engineered specifically for modern flat cable. Its compact ergonomic design means it's comfortable to use throughout the day and small enough to live permanently in a pocket or tool pouch, so it's always close to hand. Sometimes innovation is less about adding extra features and more about removing unnecessary effort. Cable Bug has been designed to make one of the most common tasks on-site quicker, safer and more consistent.

How much input did professional electricians or trade users have during the development and testing process, and did any feedback directly influence the final product?

Trade feedback sits at the heart of our product development process. Our ongoing research with electricians consistently told us they wanted a tool that genuinely saved time and made a repetitive job easier. That insight was the starting point for Cable Bug. To explore how best to solve the problem, we worked with the product design course at Bangor University, who developed a range of prototype approaches. Their work pointed clearly towards bladed solutions as the strongest direction, and those ﬁndings informed our product development team as they set about creating Cable Bug.

The result is a compact, intuitive tool that's comfortable to carry and integrates naturally into an electrician's everyday work gear. Accuracy and durability are critical on-site considerations. What testing or performance standards has Cable Bug been subjected to, to ensure it can cope with demanding working environments?

Professional electricians and installers expect tools to perform consistently in demanding conditions, day after day, so durability and reliability were key priorities throughout Cable Bug's development. The product has undergone extensive testing to ensure it delivers consistent stripping performance across repeated use, including on tougher LSOH cable. Materials and construction have been selected to withstand the knocks, drops and daily wear associated with professional use while maintaining reliable performance over time. Cable Bug has also been speciﬁcally engineered so that it's impossible to damage the inner cables during stripping, giving electricians complete conﬁdence in the quality of every strip. Ultimately, electricians judge a tool by how it performs after months of daily use, not just when it's new. That's the beauty of the simplicity behind Cable Bug's design – it has been engineered to deliver dependable results every time it's picked up.

DRIVING THE CHARGE

Emily Holland, Head of Training & Culture at Rolec, explores the evolving EV charging landscape and the knowledge, technology and support contractors need to capitalise on growing opportunities. requirements, future expansion, and ongoing management all influence system design and installation. Location Different charging environments require alternative hardware solutions, with workplace, public, residential, and ﬂeet applications all presenting distinct operational demands. For example, exposed or high-traffic environments often require a more robust infrastructure that offers durability and vandal resistance.

he EV industry is evolving at an unprecedented pace, and navigating this rapidly changing landscape requires expertise, partnerships, and long-term thinking. Rolec has consistently demonstrated these principles, establishing itself as an innovator in EV charging solutions. No longer a future-facing trend, EV charging is a day-to-day reality influencing installation requirements across residential, commercial, workplace, fleet, and public environments. As adoption continues to accelerate across the UK, it’s becoming an increasingly significant part of the electrical contractor’s workload. As things have progressed, EV charging has evolved from a specialist offering into a core service area, creating new opportunities for growth while introducing new technical considerations. Charging speeds, site requirements, connectivity, load management, interoperability, and software integration are all key factors in successful project delivery.

108 September 2026

With demand growing, contractors are increasingly expected to provide guidance that goes beyond installation alone. Customers are looking for trusted partners who can help them select the right charging solution, future-proof their infrastructure, and maximise long-term value from their investment. Home or commercial use EV charging In the case of domestic installations, homeowners are typically seeking a charging solution that combines affordability, reliability, and ease of use. Contractors therefore need products that are straightforward to install while delivering dependable performance for the end user. Rolec’s EVO, ZURA, and BasicCharge ranges have been developed with these priorities in mind, helping installers deliver cost-effective home charging solutions without compromising on quality. Commercial EV charging projects often require contractors to consider factors beyond the charger itself. Site layout, electrical capacity, user

Outlet options Commercial sites are increasingly looking to maximise charging availability while minimising infrastructure costs. Dual and quad outlet units can help reduce groundwork, cabling, and installation time while increasing the number of charging outlets available on-site. Multi-outlet solutions such as Rolec's HEX charger are helping operators maximise charging availability from a single installation footprint. Connectivity challenges Reliable connectivity is essential for monitoring, billing, and access control. However, this can become challenging in underground car parks or remote locations where signal strength may be limited. To address this, Rolec’s charging solutions offer multiple connectivity options, including 4G, Wi-Fi, and Ethernet, ensuring chargers remain online 24/7. Charging speeds Charging speeds range from 7.4 kW AC fast charging to ultra-rapid DC solutions up to 650 kW, depending on application and site requirements. In commercial and ﬂeet environments, operational efficiency is critical, with vehicle downtime, turnaround times, and site utilisation all key considerations.

108_PE_SEPT26_Layout 1 30/07/2026 12:42 Page 109

Data management The ability to extract and analyse data is becoming increasingly important for commercial operators. Access to detailed reporting, including energy consumption per vehicle, enables a clearer understanding of operational costs and fleet efficiency and chargepoint utilisation. Innovation in EV infrastructure Alongside growing demand, EV charging technology continues to evolve rapidly. The most significant developments aren’t just about faster charging speeds, but also smarter systems and more efficient energy management. Load management Load management has moved from an optional feature to a standard requirement. Dynamic load balancing is now frequently used to prevent overloading supply infrastructure, particularly in multi-charger set-ups. These systems allow several chargepoints to operate within available capacity by intelligently distributing power across a site. Interoperability OCPP (Open Charge Point Protocol) has become increasingly important in preventing vendor lock-in. Customers are actively seeking flexibility across networks and software platforms, rather than closed ecosystems. Rolec supports this approach with products designed to

be natively OCPP compliant. The company currently works with more than 45 chargepoint management system (CPMS) partners worldwide. Integrated software The value of EV charging is no longer deﬁned solely by hardware. Back-office platforms play a critical role in monitoring, billing, remote management, and energy optimisation, shifting purchasing decisions towards total system capability rather than unit price alone. More than ever, EV charging is no longer being treated as a standalone technology but as a core part of the larger energy ecosystem, where integration and interoperability are key decision factors when specifying infrastructure. DC charging for destinations and ﬂeets remains one of the most active areas of development, driven by the need for future-proof ultra-rapid charging solutions that perform reliably in high-use operational environments.

Knowledge is key With installation requirements becoming more varied, contractors are expected to understand not only charger hardware, but also load management, connectivity options, software platforms, energy optimisation, and future expansion considerations. In response, leading manufacturers are placing greater emphasis on knowledge transfer, an approach that sits at the foundation of Rolec’s strategy. This includes enhanced technical support, training, and project assistance. At Rolec, this extends beyond product supply, supporting contractors throughout the project lifecycle – from initial enquiries and specification support through to commissioning, onboarding, and handover. This collaborative approach reflects a broader shift across the EV industry, where successful project delivery depends on strong partnerships between manufacturers, contractors, consultants, and end users. Rolec’s support is reinforced through hands-on training, access to technical resources, and practical guidance across a wide range of EV infrastructure applications. With over 35 years of manufacturing experience, the company continues to develop charging solutions that prioritise reliability, flexibility, and ease of installation.

Could protecting the point of ignition redefine electrical safety as we know it? The Engineering Team at ASES GROUP takes a closer look.

THE HEAT IS OFF

he history of electrical engineering is one of continual innovation, driven by a common objective to reduce risk before it becomes danger. From fuses and MCBs to RCDs, smoke alarms, SPDs and AFDDs, each advancement has addressed a recognised vulnerability and added another layer of protection. Collectively, these technologies have made modern electrical installations safer than ever. Yet one question remains: what protects the precise location where many electrical fires can begin? Behind socket outlets, switches, fused connection units and junction boxes are electrical terminations expected to operate reliably for decades. During their service life, these connections experience repeated heating and cooling cycles, while conductors expand and contract, materials age and electrical loading changes. Over time, these processes can increase contact resistance, potentially resulting in localised heating within the enclosure. This may remain invisible to occupants and undetected by conventional protective devices. The progression can be gradual. Increased contact resistance leads to localised heating, followed by insulation degradation and, potentially, ignition. By the time smoke becomes apparent, combustion may already have developed inside the electrical enclosure. This raises another important point – should protection begin closer to the potential source of ignition?

Moving protection closer to the hazard Every significant advancement in electrical safety has progressively moved protection closer to the risk. MCBs respond to overloads and short circuits, RCDs disconnect dangerous earth leakage currents, while smoke alarms provide vital warning once combustion products enter the occupied space. Each performs a vital role. However, none is specifically designed to suppress combustion within an electrical back box itself. Recognising this has led engineers to consider a different approach, by protecting the confined space where ignition may occur. This philosophy has driven the development of ASES SHIELD, an autonomous technology designed specifically to protect the electrical enclosure itself. Installed discreetly behind a standard socket outlet or switch, ASES SHIELD monitors thermal conditions within the back box without altering the appearance or normal operation of the finished installation. When abnormal temperatures indicative of a developing fault are detected, the system initiates electrical isolation by activating the circuit’s RCD. Should ignition still occur, an integrated clean extinguishing agent is automatically released within the enclosure, helping to suppress combustion before fire can spread beyond the back box. Rather than replacing established protective devices, the technology

introduces an additional layer of defence where conventional protection has historically ended. Designed for easy installation ASES SHIELD has been engineered to integrate into conventional electrical back boxes while remaining concealed after installation. It requires no programming, external power supply or routine maintenance. The latest power socket range further simplifies installation through screwless conductor termination, colour-coded connections and inspection openings that allow installers to verify electrical parameters. Modern electrical installations must accommodate changing patterns of use, increasing loads and decades of service. As buildings evolve, fire protection strategies must evolve with them. Protecting the point of ignition doesn’t replace established protective devices, good electrical design or competent installation. Instead, it complements them by addressing a hidden area that has traditionally received comparatively little direct protection. As understanding of electrical fire behaviour continues to develop, could localised protection within the electrical enclosure represent the next logical evolution in electrical safety?

GETTING THE PRIC£ RIGHT? Drawing on years of industry experience, Electrical Estimator, Adam Berry, explains why he has created a practical playbook to help others navigate the complexities of estimating.

fter leaving school at 17, I entered the electrical industry by joining a small local electrical ﬁrm, completing my apprenticeship on mainly commercial and industrial projects, with a few large domestic jobs thrown in. Following a decade on the tools, I moved into the office as an Estimator, before progressing into Contracts Management, however I soon realised estimating was where my strengths lay, so I returned to it. Over recent years, I’ve worked for Tier 1 Main Contractors on M&E projects valued up to £150 million, and I now estimate the electrical element of commercial and data centre projects for a Tier 1 MEP ﬁrm.

Few practical resources One of the main reasons I decided to write The Electrical Estimator’s Playbook is through my own first-hand experience of how difficult that initial move from the tools into estimating can be. When I was first looking to make the transition, there was no structured training programme or practical manual explanation of how to estimate electrical projects from start to finish. Much like my apprenticeship, I learned on the job with support from experienced colleagues, but plenty came through trial and error. As my career progressed, I realised little had changed. While there are excellent resources covering electrical installation and technical standards, there wasn’t a practical guide dedicated to electrical estimating in the UK. I wanted to create the resource I wish had

112 September 2026

existed when I started – something practical, easy to follow and based on real-world experience rather than theory. Building confidence The book is aimed at electrical estimators, electricians considering a move into estimating, and contractors wanting to develop their commercial understanding and tendering skills. It guides readers through the estimating process, starting with the fundamentals before progressing to contracts, risk management, procurement, negotiations, BIM, AI and preconstruction. For working electricians and smaller contractors, I hope it provides the confidence to take the next step. Many excellent electricians are capable of delivering larger projects but can be held back by uncertainty around pricing them accurately. While experience will always be invaluable, the book provides a framework and practical processes to help readers progress from pricing smaller works to confidently tendering for projects worth £350,000 and beyond. More than counting costs One of the biggest estimating mistakes I see is focusing on material and labour costs while overlooking the wider commercial and contractual picture. Incomplete scope reviews, failing to identify Contractor Designed Portions (CDP), misunderstanding contract conditions, underestimating preliminaries and failing to qualify assumptions can turn a potentially profitable project into a difficult one.

PROFESSIONAL ELECTRICIAN

Another common issue is relying too heavily on drawings without properly reviewing the specification, where important requirements affecting cost and programme can be missed. Good estimating involves understanding risk, identifying scope gaps, interpreting technical documents, engaging with suppliers and subcontractors, and building a competitive, commercially robust tender. Throughout the book, I cover practical techniques for take-offs, building costs from first principles, reviewing tender documentation, preparing clarifications, understanding contracts and submitting professional tenders. Above all, I want readers to develop a structured approach and the confidence to make informed commercial decisions, rather than relying on guesswork.

DEBUNKING THE EV MYTH Tom Bloor, Managing Director at evec, looks at why electric vehicles are becoming one of Britain's greatest electricity grid assets rather than the burden many may still believe them to be.

or years, one myth has overshadowed the EV industry – that Britain's electricity grid won't cope if everyone switches to electric vehicles. It's an understandable concern. As transport and heating become increasingly electrified, stories about grid capacity have fuelled fears that growing demand will overwhelm the network. The events of the recent UK summer only intensified that debate. Britain experienced multiple unprecedented Electricity Margin Notices from the National Energy System Operator (NESO) as heatwaves increased electricity demand while low wind generation and reduced European power supplies tightened capacity. Traditionally associated with winter, these warnings demonstrated the growing challenges of balancing the grid during periods of extreme weather. But, in my opinion, the conclusion many people draw is wrong. Electric vehicles are not a threat to the grid – they're part of the solution. Working alongside flexibility specialist Axle Energy, evec is transforming connected EV chargers into intelligent energy assets that help balance demand, maximise renewable energy use and improve grid resilience. Turning chargers into grid assets Traditionally, an EV charger simply draws electricity from the grid to charge a vehicle. Through evec's vecFLEX platform, however, chargers become active participants in Britain's energy system.

when required while helping to stabilise the grid – and earning rewards for doing so. The scheme offers up to £140 in the first year and £120 annually thereafter, with more than £300,000 already paid to customers since its launch in March of this year. Customer feedback has been equally positive, with 93% reporting they’re satisfied or very satisfied with vecFLEX, while 96% intend to continue participating. In reality, every evec charger has the potential to become part of Britain's energy infrastructure. Through our partnership with Axle, customers aren't simply buying a charger – they're becoming part of a smarter, cleaner and more resilient energy system. Drivers simply tell us when they need to charge, we handle the rest, and they get rewarded for supporting the grid.

“Electric vehicles are not a threat to the grid – they’re part of the solution.” Powered by Axle Energy's ﬂexibility technology, vecFLEX allows customers to schedule when they need their vehicle ready. Charging is then automatically managed in the background, with sessions brieﬂy paused during periods of peak demand and shifted to times when electricity is cleaner, cheaper and more plentiful. Participation is effortless for customers. Drivers receive a fully charged vehicle

PROFESSIONAL ELECTRICIAN

Removing barriers to flexibility Historically, participation in flexibility schemes has been limited by metering requirements. Many required households to have compatible smart meters operating under Half-Hourly Settlement (HHS), excluding a significant proportion of UK homes. evec has helped remove that barrier by becoming the first affordable EV charging manufacturer to achieve CoP11 approval. Rather than relying on household smart meters, participation can instead be measured directly through the charger itself. This means around 90% of evec customers are now eligible for vecFLEX regardless of their smart meter status, dramatically widening access to flexibility services.

114_PE_SEPT26_Layout 1 30/07/2026 13:07 Page 115

Consumer culture The real challenge facing Britain's electricity system isn't how much electricity EVs consume – it's when they consume it. Because vehicles spend most of their time parked, charging can be shifted away from periods of peak demand without affecting drivers. This reduces pressure on the network, absorbs surplus renewable generation and helps avoid expensive infrastructure upgrades that would otherwise be funded by consumers. Flexible charging is also vital for making better use of renewable energy. Wind and solar generation naturally ﬂuctuate, with clean electricity sometimes going unused when supply exceeds demand. Intelligent EV charging can absorb that surplus energy, reducing waste while increasing reliance on renewable power.

“The real challenge facing Britain’s electricity system isn’t how much electricity EVs consume – it’s when they consume it.” The heatwaves experienced this summer provided a clear demonstration of why this ﬂexibility is becoming increasingly important. During June and July, NESO sought an additional 1,900 MW of capacity, with securing extra supply expected to cost around £10

million. At the same time, reduced nuclear generation in France highlighted how interconnected Europe's electricity systems have become. For evec, these events reinforce that ﬂexibility will become one of the UK's most valuable energy resources. Since launching in 2022, our mission has been to make EV charging more affordable and accessible. Through vecFLEX, installers, wholesalers and customers can now beneﬁt from a charger that continues delivering value long after installation – reducing costs, supporting renewable energy and helping build a smarter, more resilient electricity network for Britain.

IDEAL helps to ReStore Romford charity shop With more than 130,000 families living in the UK without permanent housing, IDEAL Electrical is trying to make a difference by leveraging the skills of its electrician network to become part of the solution. As an example, IDEAL recently brought together local electricians and industry volunteers for a one-day service event at Habitat for Humanity’s Romford ReStore, with the goal of enhancing the space that serves both as a retail location and supports local residents who face the misfortune of experiencing housing insecurity. During the event, volunteers completed key electrical improvements throughout the space, including installing hot water heaters, pendant lighting and two-way switching stair lighting, as well as replacing hand dryers and relocating lighting displays. These upgrades helped improve the functionality and experience of the ReStore, allowing the site to better serve customers, volunteers and local residents seeking support.

The Romford ReStore, which opened in November 2024, is the ﬁrst ReStore in Great Britain. The home improvement charity shop sells donated new and gently used furniture, household goods and building materials, with proceeds helping fund Habitat for Humanity’s work to create affordable housing and sustainable communities. The location also serves as a Community Hub, offering women and families at risk of homelessness or housing poverty a welcoming place to access advice, practical support, volunteer opportunities and skill-building resources.

The activation also addressed a major challenge in housing support: access to basic furniture and household goods. In the UK, only 2% of social housing is currently furnished, leaving many new residents struggling to afford essentials such as beds, wardrobes and kitchen appliances. At the same time, more than half of the 1.6 million tons of home furnishings and household materials discarded each year by homeowners could be re-used with little or no repair. Through efforts like the Romford ReStore activation, IDEAL Electrical and Habitat for Humanity Great Britain are working to address housing insecurity by improving community spaces, supporting access to affordable household goods, reducing waste and investing in long-term solutions. The activation is part of IDEAL Electrical’s three-year partnership with Habitat for Humanity, reﬂecting a shared belief that building stronger communities requires more than ﬁnancial support. By bringing electricians, volunteers and industry partners directly into the work, IDEAL is helping turn professional skills into practical community impact.

ESP has recently provided fire safety for a major mixed use regeneration project. The transformation of Stroudley Walk in Bromley by Bow is creating a new neighbourhood at the heart of East London. The development will deliver 274 new homes, including 82 available through London Affordable Rent and 33 for shared ownership. Homes will range from studio apartments to four bedroom family houses, forming a diverse and inclusive community. The regeneration spans four new blocks positioned between Bruce Road and Bromley High Street, close to Bow Road. Alongside the residential element, the scheme will introduce flexible retail, commercial and community spaces, as well as significant public realm improvements. A new pocket park and a part pedestrianised street will help create a safe, welcoming environment for residents and visitors. Total protection Against this backdrop, the project required a fire safety system that could support a complex, multi-building development while ensuring long term reliability and ease of maintenance. The electrical team selected ESP’s MAGfire addressable fire alarm system to provide comprehensive protection across the entire site.

ESP works it’s MAGic on regeneration project The installation covers the full development, with addressable control panels positioned within each block and a network of detectors, call points, and sounder/visual alarm devices distributed throughout corridors, apartments, plant rooms, and communal areas. The addressable fire system spans the entire site and is configured to allow clear device identification, rapid fault finding, and tailored cause and effect programming for each building. One of the key reasons for selecting MAGfire was the ease of installation and commissioning. The addressable architecture reduced wiring complexity and allowed the team to configure the system efficiently, even across multiple buildings. The ability to scale the system in the future was also a major advantage, particularly for a development expected to evolve over time. Clear oversight of all devices The system now operates as a fully integrated network, giving facilities management clear oversight of all devices and panels. Each building’s panel communicates with its associated devices, ensuring rapid detection and alerting while maintaining full compliance with BS 5839 1. The flexibility of the MAGfire platform also allowed the team to tailor evacuation strategies for both residential and commercial areas. DPC Electrical Contracts and the wider DPC Electrical Team completed ESP’s fire alarm training prior to installation, which

Comprehensive circuit protection for modern installations As electrical installations become increasingly sophisticated, effective circuit protection has never been more important. With homes and commercial buildings incorporating technologies such as solar PV, battery storage, EV charging and heat pumps, today's electrical systems require protection against a wider range of faults while remaining straightforward for installers to specify and ﬁt. One area of growing importance is protection against transient overvoltages. Modern properties contain more sensitive electronic equipment than ever before, making Type 2 Surge Protection Devices (SPDs) an essential consideration. By helping to protect connected equipment from power surges, SPDs can reduce the risk of costly damage and improve long-term system reliability. Incorporating AFDD protection

Fire safety is also receiving greater attention. The latest Wiring Regulations place increased emphasis on Arc Fault Detection Devices (AFDDs), which can detect dangerous arc faults caused by damaged cables, deteriorating insulation or loose connections before they develop into a fire risk. Incorporating AFDD protection where appropriate can

help improve overall installation safety while supporting regulatory compliance. Alongside enhanced protection, installers continue to demand products that make life easier on site. Features such as generous wiring space, flexible cable management and installer-friendly designs can help reduce installation time while maintaining high standards of workmanship. Large and varied offering

Future-proofing installations is equally important as electricity flows become increasingly bidirectional through the adoption of renewable technologies. Consumer units and protective devices must now accommodate changing energy demands while remaining compliant with evolving standards. Developed with these requirements in mind, the Timeguard Circuit Protection Range combines comprehensive protection with practical installation features. The range includes factory-fitted Type 2 SPDs, AFDD/RCBO combinations and bidirectional RCBOs designed to support renewable energy applications, providing electricians with flexible solutions for both new installations and consumer unit upgrades.

With electrical systems continuing to evolve, circuit protection remains the foundation of every safe and reliable installation. By combining the latest protective technologies with installer-focused design, the Timeguard Circuit Protection Range helps electricians deliver compliant, future-ready installations with confidence.
