Editor’s Viewpoint

Who exactly is the ‘cowboy’ crackdown really for? Few people working in the construction sector would argue against measures designed to protect customers from rogue traders. Every electrician, builder, plumber and installer has encountered the fallout from someone else’s poor workmanship at some point – money taken upfront, work left unfinished, promises that disappear faster than a bag of cable ties on a busy site. So, on the face of it, the government’s latest crackdown on so-called “cowboy builders” sounds perfectly reasonable. New trusted trader schemes, milestone-based payment systems and greater transparency are all intended to help consumers identify reputable firms and avoid being ripped off. Most construction professionals will probably agree with that principle. The question is whether this is really where the biggest problems in construction lie. After all, reputable contractors already operate within a framework of qualifications, certifications, competent person schemes, reviews and recommendations. Many customers check online reviews, use platforms such as Checkatrade, or rely on industry-recognised registers before employing someone. The electrical sector, in particular, has spent years building systems designed to demonstrate competence and accountability. So when government announces another layer of oversight, many tradespeople naturally start asking a different question: is this genuinely about consumer protection, or is it also about visibility, data collection and revenue? Because once work is digitally recorded, payments are tracked and improvement projects become easier to monitor, it inevitably creates a more complete picture of what is happening inside the nation’s housing stock. That may be useful for consumers. It may also prove useful for tax authorities, policymakers and local authorities seeking ever more detailed information about property values and home improvements. Perhaps that is simply an unintended consequence. Perhaps not. Meanwhile, many legitimate construction businesses are wondering where their own

protection is. What happens when a limited company racks up substantial debts to subcontractors, suppliers and tradespeople before quietly disappearing into insolvency, only for a similar company to emerge a few months later with a slightly different name above the door? Many contractors have lost thousands through exactly that scenario. Yet there seems considerably less political enthusiasm for tackling those particular cowboys. Small construction firms are already navigating rising material costs, increased compliance requirements, constant regulatory changes, higher employment costs, business rates and an ever-growing administrative burden. Most are not asking for special treatment. They simply want a level playing field and a system that recognises the pressures of running a legitimate business. Which brings us back to my current favourite subject – our good friends in Westminster. Governments of all guises seem remarkably enthusiastic about identifying problems in construction, while displaying rather less urgency when addressing failings closer to home. If rogue behaviour is the issue, perhaps the search should not stop at the trades. The public has spent years watching political scandals, questionable procurement decisions, failed projects, wasted public money and individuals who somehow manage to remain in positions of influence despite behaviour that would see most tradespeople removed from site before breakfast. Maybe before introducing yet another scheme to identify the cowboys in construction, government should spend a little more time identifying the cowboys within its own walls. Because most construction professionals and electricians I know are already held accountable for the work they do. Many voters are still waiting to see the same standards applied elsewhere. Have a good month and enjoy the issue.

90 years of ventilation excellence with Vent-Axia Vent-Axia is marking its 90th anniversary this year, nine decades after engineer and inventor Joe Akester brought the company’s first ventilation product to market. The British manufacturer traces its beginnings to 1936 and the Silent 6, the world’s first electrically operated window ventilator. Its early customers included Sir Winston Churchill, who purchased Vent-Axia fans for his Chartwell home in 1945. As demand for mechanical ventilation increased, the company expanded, with its sales team taking Vent-Axia products to customers across Britain. A number of products subsequently became milestones in the company’s history. The Standard Range was launched in 1961 and its one-millionth unit was manufactured by 1970. The popular

T-Series followed in the 1980s, which became the UK’s No. 1 commercial fan and appeared in the 1986 film Aliens. Meanwhile, in 1992 Vent-Axia introduced the world’s first Safety Extra Low Voltage (SELV) fan to meet the requirements for electrical safety in bathrooms. As the industry changed, the following decades saw the focus of ventilation change. Vent-Axia’s Lo-Watt in 1997 and Lo-Carbon ranges in 2007 paved the way, reflecting the move toward lower energy ventilation. This was followed by developments in heat recovery, demand-controlled ventilation, as well as connected controls, including the Svara – the first UK unitary fan with app control. Today the evolution continues. Among Vent-Axia’s latest products is the Lo-Carbon Pure Air Cleanse – a

continuous-running dMEV fan. Its arrival comes as continuous dMEV takes a growing share of the UK fan market, now accounting for one in four fans sold. Moving from Putney to Crawley in West Sussex in 1958, Vent-Axia remains headquartered in Crawley, where it designs and manufactures ventilation products for residential and commercial applications. The company is also using its anniversary to uncover more of its product history. It is asking electricians, installers and customers to share photographs and stories of Vent-Axia products – including older fans that may still be in operation – and tell them why they are a fan of Vent-Axia.

COVER STORY

THE HEAT IS E AD E TR TH

Today’s storage heaters are a far cry from their predecessors. The experts at Rointe explore how intelligent charging, high heat retention and direct connectivity are redefining electric heating performance.

ONYX!

EE FR

igh heat retention, intelligent charging and direct WiFi are changing what electricians can expect from a storage heater. Rointe’s ONYX brings these technologies together in a system designed to improve heating performance while making speciﬁcation, installation, maintenance and handover more straightforward. A quality heating product must be practical to install, simple to conﬁgure and easy for the customer to understand. Connected products also add another consideration: how much extra hardware is needed to get them online? ONYX addresses those practical requirements while tackling one of storage heating’s fundamental challenges - keeping stored energy available until it’s needed.

Changing the equation ONYX is a high heat retention storage heater with independently tested performance and SAP accreditation. It retains more than 55% of its stored heat after 16 hours, allowing more of the energy accumulated during charging to remain available later in the day. The objective is not simply to charge during an off-peak period, but to retain that energy until the property needs heat. Better retention reduces losses before use. But retention is only half of the equation. When and how much the heater charges is equally important.

Smart Charging responds to real demand Because no storage heater can retain 100% of the energy it stores, the longer heat remains inside the unit before its needed, the more will naturally be lost. ONYX addresses this through Smart Charging. Rather than simply charging throughout the available off-peak period, its control algorithm calculates how much stored heat will be required for the following day and when charging needs to begin to reach that level at the right time. By starting as late as practicable within the charging window, ONYX reduces the time energy remains stored before use, helping to minimise standing heat losses.

Importantly, intelligent charging isn’t just about applying a predetermined profile. Systems based largely on fixed parameters may need additional charging margins to account for changing conditions and avoid leaving insufficient heat available later in the day. ONYX takes a more adaptive approach, continually calculating the heating requirement according to conditions affecting the property, rather than relying on a fixed additional charge. This allows it to respond more precisely to demand and changing indoor and external conditions. The aim is to avoid both extremes: a) undercharging, which can leave

016_PE_OCT26_Layout 1 31/08/2026 16:08 Page 17

insufficient heat when needed, and b) overcharging, which stores energy that may never be required. The great news is that this intelligence is built into the heater, reducing reliance on manual charge adjustments. No hub, no extra box Connected heating can become unnecessarily complex if every installation requires an additional gateway, smart box or proprietary communication device. ONYX avoids that layer as WiFi Direct is integrated into the heater, allowing it to connect directly to the property’s wireless router without an additional hub. Once connected, it can be managed through the Rointe Nexa App. When commissioning, that means one less device to install, power and pair. The heater also displays charge level, target temperature, programmes and operating modes, so the customer isn’t dependent on the App for basic control. A simple handover A good installation can still result in a call-back if the customer doesn’t understand the unit’s controls. ONYX is designed to make handover clearer. The installer can explain the core functions directly at the heater, while Rointe Nexa provides a single interface for temperature adjustment, programming, energy monitoring and device locking. Combining automatic charging, direct connectivity and a clear local interface reduces the number of separate systems the installer has to conﬁgure and explain.

Designed for the changing energy-performance landscape Heating speciﬁcation is also becoming more connected to the wider energy performance of the property. ONYX is already assessed within the current SAP framework, while the way homes are evaluated is set to evolve as the UK moves from SAP towards the Home Energy Model (HEM) and a redesigned EPC. The proposed framework moves beyond reliance on a single headline rating, introducing separate measures that include heating-system performance, energy cost, fabric performance and smart readiness. This makes the way heating is controlled, managed and integrated within the home increasingly relevant alongside appliance efficiency. With high heat retention, demand-led Smart Charging and connected control through Rointe Nexa, ONYX has been developed around many of the principles that are becoming more important in this changing assessment landscape. Increasingly, the question isn’t only about how a heater performs, but also how intelligently the complete system manages energy.

From one heater to a complete electric heating system The bigger opportunity for installers is not ONYX in isolation. Rointe is building its connected product range around Rointe Nexa, its own control platform. Compatible Rointe radiators, electric towel rails, water heaters, underfloor heating controls and ONYX storage heaters can all be brought together within the same ecosystem. That allows the electrician to specify the most appropriate technology for each space rather than forcing one solution across the whole property. A project could combine high heat retention storage heating where off-peak energy use is advantageous, responsive electric radiators elsewhere, a towel rail in the bathroom, electric underfloor heating where appropriate and connected hot water - all controlled through one Rointe Nexa environment. That creates a more coherent route for the installer - from specification to commissioning and handover – through the use of one manufacturer, compatible connected technologies and a single App, rather than a collection of unrelated products and control platforms.

numbers, while there’s still time to do something about it.

s the MD of a Gas Safe registered and Heat Geek certified company, I install air source heat pumps and underfloor heating, which means I now spend a surprising amount of my week talking about consumer units, spare ways and DNO forms. One thing I’ve learned over the years is that, on a heat pump job, the electrical side isn’t just an afterthought. Found late, it’s the thing that can turn a tidy two-week programme into a doorstep negotiation nobody enjoys. This is what the job looks like from my end, and what the electricians I rate do differently from others.

2 The unit needs its own circuit, and Is there a way on the board?

the cylinder's immersion wants one too. The classic mid-job variation is the consumer unit nobody opened at the time of the survey – full, obsolete, or wired in ways that make an assessor wince. A board change found on day one of the install week blows the programme and sours the customer. The same board change found at the point of survey is just a line in the quote.

Where the job is won: the survey A heat pump job is decided before anyone lifts a floorboard. I survey room-by-room before I quote, and three electrical questions get answered on that first visit, not during install week:

An EV charger, an induction hob and a heat pump on the same single-phase supply is now a normal combination, and it’s the whole picture that matters, not just the heat pump on its own. I want to have that conversation at the point of survey, with the electrician's

Most domestic units sit on the type-approved register and go through the connect-and-notify route. Bigger units, looped supplies or a constrained bit of network mean applying first, and an approval wait has to live in the programme from the start, not surface in week two as a surprise everyone blames on someone else. I price all three of these up front. My quotes carry the known discoveries as line items rather than leaving them to be negotiated on the doorstep, and the electricians I work with quote their share the same way. Customers will accept almost any scope if they hear it before they sign. They will accept almost nothing after. Install week: the interface On our jobs the electrician's scope is well defined.

the outdoor unit, sized for the route it actually takes rather than the nameplate alone, with a weatherproof local isolator within reach of the unit. The immersion circuit to the cylinder also requires consideration, and protection should be arranged to suit the board and the requirements of BS 7671, which I leave entirely to the electrician. After all, that’s their call and their certificate. Then there’s the controls wiring, which is the part heating engineers get precious about – and with good reason. A modern heat pump lives or dies by its controls, which can include flow and return sensors, an outdoor sensor for weather compensation, room influence, and sometimes a mixing circuit for underfloor heating running at its own temperature. Those runs are low voltage and they don’t want to share a route with power cables. A heat pump that cycles constantly because a sensor reads nonsense will drink electricity, and the customer will be told, wrongly, that heat pumps don’t work. Ten careful minutes clipping a sensor run properly is the cheapest efficiency gain on the whole job. Commissioning day Commissioning needs the unit energised, the immersion available and the controls talking before we start, so power has to be on and tested first. When the two trades plan that day together it runs like clockwork. When they don’t, someone inevitably stands in a kitchen watching someone else work. The electrical certificate then goes into the handover pack alongside the MCS paperwork. That pack is what the customer's warranty and compliance hang off, so a late certificate holds the whole thing hostage. The electricians I use are never the reason a pack is late, which is one of the reasons I keep using them. What the best ones do After a few years of these jobs, a clear pattern has emerged. The electricians who make heat pump work profitable and painless do five things: 1 I They ask for the manufacturer's spec sheet before they quote, because starting characteristics and maximum

demand vary between units. 2 I They look inside the board at the point of survey, not on day one. 3 I They flag network operator constraints early instead of assuming notification is a formality. 4 I They price the awkward findings as numbers, not shrugs. 5 I On commissioning day they’re on-site or on the phone, because that’s when their work, and mine, finally meet. The pipeline point Heat pump installations are growing year-on-year, and every single one needs an electrician.

PROFESSIONAL ELECTRICIAN

From where I stand, that’s a steady stream of well-deﬁned, repeatable work that’s the same shape each time, quoted from a survey, done in a day or two, certiﬁcated and paid. The heating side is crying out for electricians who’ve learned the shape of the job once and can then repeat it calmly. Find a heating engineer whose surveys you trust and who agrees who prices what, and the variations argument disappears from both of your lives. The customer gets a warm house and a boring, predictable install. In fact, ‘boring’ is the compliment we’re both aiming for at the end of the day.

Q&A

UNITED WE BRAND

BEX Group has recently unveiled its new identity, bringing together three well-respected brands under one banner. We put the questions to Stephen Harpur, Chief Commercial Officer, as he explains the thinking behind the move and what it means for the electrical industry.

Many readers will be familiar with LED Group, so why was now the right time to introduce the BEX Group identity, and what message do you hope this sends to the industry?

LED Group is a heritage name that served us well for decades, but we felt it was time for a change. Many people don’t realise that “LED” stood for “Lighting Electrical Distribution”, rather than LED lighting technology. That made sense when ROBUS was the only brand in the business, but with the addition of FuseBox and ATC, the name reﬂected where we’d come from rather than where we’re heading. The move to BEX Group isn’t a break from the past; it’s an evolution. We kept some subtle cues, such as the original font and the three-letter abbreviation, to carry a bit of that heritage forward with us. Our aims with BEX Group are simple: to provide electrical contractors with the best products in each category, work closely with wholesalers to deliver excellent service, and continue delivering best-in-class results in everything we do. If you’ve trusted ROBUS, FuseBox or ATC in the past, that trust carries forward; we’re just better placed now to keep earning it.

22 October 2026

A good example of this investment is our new Liverpool distribution facility. With capacity for more than 15,000 pallets, it enables 24-hour UK delivery for ROBUS and FuseBox products while giving us room for future growth. ROBUS, FuseBox and ATC have each established strong reputations in their respective sectors. How will their individual strengths be maintained while benefiting from being part of BEX Group?

Each brand retains its own identity and customer relationships. Preserving what

PROFESSIONAL ELECTRICIAN

made each business successful has always been a key priority. Our strategy is to support sustainable growth without changing the DNA of the brands. Behind the scenes, BEX Group brings shared expertise, infrastructure and technical capabilities. This allows us to respond more effectively to global challenges, such as supply chain disruption, in ways that would be tough for a smaller business. The result is a better level of service for our customers. As the group expands, we can also act as a single-source provider. Recently, we supplied ROBUS lighting, FuseBox circuit protection and ATC heating and hand-drying solutions to a commercial project in Ireland through one wholesale customer. Delivering multiple product categories through a single point of contact reduced timescales and simpliﬁed the process for everyone involved. Building electrification is central to the new group’s identity. Which technologies or opportunities do you believe will have the biggest impact on electrical contractors over the next decade, and how is BEX Group positioning itself to support that transition?

022_PE_OCT26_Layout 1 01/09/2026 09:35 Page 23

Electriﬁcation is being driven by several factors, including decarbonisation, the continued government support for EV adoption, solar technology and the move away from traditional boiler systems towards heat pumps and other electric heating solutions. As buildings become more energy efficient, smaller electrical heating solutions, such as ATC’s thermal radiators, will also become increasingly attractive. Alongside these technologies, demand will grow for the supporting infrastructure, including circuit protection, cabling and cable management. What makes BEX Group different is our commitment to supporting contractors through this transition, starting at the product development stage. We speak with electricians almost daily to understand what they need and how we can make installations faster and easier. Time is one of the most valuable resources an electrical contractor has, so installation speed is a major focus. A good example is FuseBox’s Irish consumer unit range, which features a terminal bar on every row rather than the industry standard of only at the top and bottom of the board. This optimisation makes installation so much quicker and simpler. We’re innovating in a product category that hasn’t really changed in 20 years! This is exactly the kind of practical innovation the industry will need as electriﬁcation increases demands on contractors.

Electrical contractors increasingly expect manufacturers to offer more than just products. How is BEX Group supporting installers through technical advice, training, specification support and innovation?

Support comes in several forms, including education, technical expertise, speciﬁcation assistance and continuous product development. We invest heavily in college engagement through initiatives such as College Connection Days and BEX Group Takeover Days. Over the past two years, ROBUS has engaged with almost 1,500 students, while more than 60 colleges have benefited from collaborations across BEX Group. FuseBox joined the college programme back in January 2026, which has already proved really popular in the further education space. These programmes help students gain experience with current technologies before entering the industry. We’ve also developed BEX Group Academy as a central hub for learning. It combines accredited CPD courses with technical and product-focused content from ROBUS, FuseBox and ATC. We work

closely with organisations such as the EDA, helping develop educational content and sharing technical expertise across the wider industry. Importantly, the Academy goes beyond technical training. Through partnerships with Dr Brian Pennie and the Electrical Industries Charity, it also provides resources focused on mental health and wellbeing. Day-to-day support is equally important. We continue to invest in technical services, including our WhatsApp technical support platform and the MyROBUS, MyFuseBox and MyATC Apps, which reward contractors for purchasing our products while providing instant access to technical information. We also recognise that time is money. That’s why we focus on delivering rapid turnaround times for project quotations, lighting designs, heating designs and custom circuit protection drawings, with most completed within 24 hours and many within just a few hours. Across BEX Group, our focus remains ﬁrmly on electrical contractors and wholesalers. As electriﬁcation accelerates and projects become more complex, we will continue investing in the products, services and support that help our customers succeed.

SPECIAL REPORT

ENTER THE

MATRIX

qualification may open the door, but it doesn’t demonstrate competence across every category of electrical work. Electrical businesses have traditionally relied on qualifications, cards and Qualified Supervisor oversight when demonstrating competence. These remain important, but competence must be considered at an individual level, matched to the work and supported by current evidence. The question is no longer simply ‘is the person qualified?’, but instead ‘what work is this person competent and authorised to undertake, under what conditions, and what evidence supports that decision?’

Following on from last month’s article, which explored the latest regulatory requirements around competency in the electrical industry, Michael Collinge MIET, Technical Director at Flexi-Orb, looks at how businesses can build a competence matrix that works.

competence matrix, and an eligible qualification shouldn’t be treated as evidence across every activity. It does, however, strengthen the need for enterprises to understand who undertakes each work category and what evidence supports that individual’s competence. In England, the direction is reinforced by the mandatory competence requirements in Part 2A of the Building Regulations 2010. Individuals undertaking building or design work must have the necessary skills, knowledge, experience and behaviours, or adequate supervision while training. Organisations must demonstrate

appropriate organisational capability, so a task-based matrix can help translate these duties into controlled appointments, supervision and authorisation decisions. A list of certificates is not a competence matrix A spreadsheet containing names, qualifications and expiry dates may be a useful training record, but it is not, by itself, a competence matrix. A working matrix connects people to defined activities, responsibilities and limitations. Its purpose is to provide a credible, reviewable picture of what each individual can do.

Why does this matter now? Electrical work is becoming more specialised. An individual who is highly capable in conventional installation work may have limited experience of solar PV, electric vehicle charging or electrical energy storage. Even within one category, competence may differ between survey, design, installation, inspection, commissioning and certification. A broad qualification or company approval shouldn’t be treated as evidence for every activity. From this month onwards, the EAS Qualifications Guide applies competence requirements to persons undertaking relevant work involving electric vehicle charging equipment, solar photovoltaic systems, electrical energy storage systems and micro wind turbines. EAS 2026 doesn’t prescribe a

SPECIAL REPORT

Start with the work, not the workforce Begin by mapping the business scope of work. Break it into functions such as survey, design, installation, inspection, testing, commissioning, certification, maintenance and supervision. Define the knowledge, skills, experience and behaviours required for each activity and the evidence expected. This prevents the matrix being shaped around certificates already held, rather than the work the business delivers.

Applying the DREAM lifecycle Develop the knowledge, skills, experience and professional behaviours required for the work, including behaviours that consistently support safety, quality and integrity.

Use clear authorisation levels Competence is demonstrated capability. Authorisation is the documented organisational decision deﬁning the work a person may undertake, together with any restrictions, supervision or limitations that apply. A practical model might include: authorised for independent work; authorised with restrictions or supervision; developing under assessment; and not authorised. The person granting authorisation must be competent and empowered to review the evidence. For example, an electrician may be authorised to install and test conventional electrical installations independently, permitted to install solar PV under deﬁned supervision, but not yet authorised to design or commission an electrical energy storage system. One person doesn’t need the same authorisation level across every category of work.

Assure the decision through review, sampling, assessment and documented authorisation.

Evidence must be proportionate and credible Not every authorisation requires another formal qualiﬁcation. Decisions may be supported by qualiﬁcations, relevant experience, witnessed assessments, completed work records, professional discussion, technical questioning and targeted development. The evidence should be sufficient, current, authentic, relevant to the activity and traceable to the individual. Higher-risk or more complex work will normally justify stronger evidence and closer assurance.

26 October 2026

Recognise existing competence and relevant transferable experience without assuming that time-served is sufficient. Evidence capability through proportionate, task-relevant and current records.

Maintain competence through practice, CPD, supervision (where needed) and periodic review.

“Handled well, competence assurance supports safer work, workforce planning and targeted development.” Turn evidence into a decision Evidence has value only when reviewed against a deﬁned requirement. The business should decide what a satisfactory evidence set looks like for each activity and who is competent and accountable to approve it. The decision should identify the authorised scope, restrictions, supervision and circumstances requiring reassessment. This creates a defensible route for recognising experienced workers without treating length of service as automatic proof of competence. Where evidence is incomplete, the response may be a focused observation, technical discussion, supervised activity or development plan rather than unnecessary repetition of learning already achieved.

PROFESSIONAL ELECTRICIAN

The matrix provides the thread connecting these stages. It shows not only the evidence held today, but also how competence will be developed, assured and kept current over time. Keep the matrix alive A competence matrix is a control system, not a document produced solely for assessment day. Review should be triggered by changes in work scope, standards, legislation, roles, equipment or technology; an incident, defect or performance concern; extended absence from an activity; or expiry of relevant certiﬁcation. CPD should support the individual’s authorised scope rather than consist only of generic hours. Make it usable The matrix should control risk while remaining simple enough for those allocating work. Avoid indistinguishable categories or colour codes without deﬁnitions. Each status should produce a clear outcome: independent work, work subject to stated controls, development under assessment, or no authorisation. Supporting evidence should be accessible, with personal information controlled appropriately.

025_PE_OCT26_Layout 1 18/09/2026 15:31 Page 27

The role of the Qualified Supervisor The Qualified Supervisor may contribute through evidence review, technical questioning, work sampling and identification of development needs. However, the business remains responsible for ensuring authorisation decisions are supported by sufficient evidence. QS oversight should assure that the competence system works effectively; it shouldn’t substitute for demonstrating the competence of each person undertaking the work. Connect the matrix to legal and industry duties Regulation 16 of the Electricity at Work Regulations 1989 requires those undertaking work that needs technical knowledge or experience to prevent danger or injury to possess it, or to be appropriately supervised. In England, Part 2A of the Building Regulations 2010 also makes individual competence and organisational capability legal requirements for building and design work.

“Qualifications show learning; competence shows capability; authorisation records what the organisation has evidenced and entrusted a person to do.” Electrotechnical assessment increasingly expects competence to be maintained and matched to the work. None prescribes a competence matrix, but a well-designed matrix can evidence assessment, supervision and authorisation. A practical minimum As a minimum, record the individual and role; work categories; qualifications and training; experience and assessment evidence; authorisation level; restrictions and supervision; relevant CPD; the

approver; and review date and triggers. The matrix should link to the underlying evidence rather than merely state that it exists. From assurance to advantage Handled well, competence assurance supports safer work, workforce planning and targeted development. Qualifications show learning; competence shows capability; authorisation records what the organisation has evidenced and entrusted a person to do. Start with one work category and identify the evidence supporting each person’s authorisation. And remember, competence is built, demonstrated and maintained every day. The next article in this series will explore how electrical businesses can keep competence current.

Updated route for adult learners confirmed As the Level 3 NVQ Diploma gets set for retirement, Kevin Sparrow, EAL’s Industry & Porfolio Manager, explains why EAL is introducing a modernised non-apprentice pathway to support adult learners working towards competent electrician status. With the electrotechnical industry continuing to evolve, qualifications must continue to reflect current practice, technologies and competence expectations. We’ve confirmed the planned retirement of the EAL Level 3 NVQ Diploma in Installing Electrotechnical Systems and Equipment (Buildings, Structures and the Environment) (501/1605/8), with the operational end date set as 31st October 2026. The qualification has supported the sector for many years, but industry expectations and apprenticeship structures have moved on. Its retirement supports a more current and consistent approach to training and assessment.

A new option for adult learners From May 2026, non-apprentice adult learners have access to a new pathway within the EAL Level 3 Electrotechnical Qualification (601/7345/2). This provides an up-to-date option for adults working in the industry who are not following an apprenticeship route but want to progress towards becoming a competent electrician. The pathway gives adult learners access to current qualification content, modern assessment expectations and greater parity with apprentice routes. This is particularly important for those retraining or formalising existing workplace experience (and are not yet classed as experienced worker).

30 October 2026

Proving workplace competence Our work with The Electrotechnical Skills Partnership (TESP) has also introduced new minimum expectations around completion timeframes, helping ensure learners gain the depth and breadth of workplace experience needed to complete a robust on-site portfolio of evidence. To support industry robustness and integrity, completion will generally occur after minimum periods of 24 months for Installation and Maintenance electricians and 18 months for Domestic electricians. These are minimum requirements; in general, it takes many years of dedicated study, workplace experience and practice to become fully competent. Learners completing in less than these durations are expected to be exceptions and will be subject to enhanced scrutiny at the AM2 gateway. This reflects the industry expectation that competence is built through meaningful, sustained workplace experience.

This should help providers plan delivery more efficiently while maintaining technical accuracy, assessment quality and compliance controls expected by industry.

Updated assessment strategy To underpin the new pathway, we’ve supported the updates with a revised assessment strategy for the on-site performance units. This helps ensure the qualification remains robust, manageable to deliver and aligned with the realities of modern electrotechnical work. The updated approach gives industry assurance that evidence reflects authentic workplace performance and the required breadth of experience, with the same emphasis on competence, integrity and safety as apprentice pathways. By retiring the older NVQ and introducing a current non-apprentice pathway, we’re supporting a clearer, more consistent and industry-led route for adult learners, employers and centres.

Supporting colleges/training providers The move will also support colleges and training providers by creating greater consistency across training for apprentices and non-apprentices. Centres will be able to work from more closely aligned qualification content, assessment expectations and evidence requirements.

CODEBREAKERS EDWARD BRETHERTON: THEY’VE DONE A LOVELY JOB OF CONCEALING THE 6 MM COOKER SUPPLY – JUST PAINT IT THE COLOUR OF THE WALL AND, OF COURSE, SUSPEND IT ABOVE THE GAS COOKER! BS 7671 contains requirements for routing wiring systems within prescribed zones to reduce the risk from mechanical damage. Further requirements apply where cables and accessories may be affected by proximity to excessive heat. The cables enter into the wall surface apparently in a diagonal direction where no accessories are present and, as such, no prescribed zone. They then enter a kitchen wall unit, potentially to the location of the cooker switch-disconnector. A closer inspection reveals what appear to be two sets of cables. This may indicate that the original cooker switch-disconnector was positioned below where the cables enter the wall. This would have been too close to the gas hob and may have resulted in a concealed joint in the wall, behind the tiles, so the cooker switch could be relocated to the wall unit. Taken together, these observations indicate the potential for danger for the cooker circuit installation, therefore, the appropriate classification code would be a C2, Potentially dangerous – urgent remedial action is necessary.

NEIL MAIDMENT: WE WERE IN FOR A RECENT FUSEBOARD CHANGE. CLEARLY THE PREVIOUS ELECTRICIAN DECIDED ‘NO MCB, NO PROBLEM’! A fundamental principle of BS 7671 is the protection of persons, livestock and property against damage or injury that may be caused by any overcurrents likely to arise in our installations. The provision of a suitable overcurrent protective device is normally how this is achieved. When correctly co-ordinated with our conductors, these devices will disconnect a circuit under fault before the wiring system can be damaged by excessive temperatures and possibly create a risk of fire (and also within the required time when the fault is to earth.) The absence of an OCPD, as indicated in the image, can only be seen as the consequence of negligence and incompetence. There is no justification for not providing overcurrent protection for the installed circuit. Whilst there may have been extenuating circumstances where the existing circuit-breaker had suffered a fault and possibly the circuit in question was an essential item of equipment that had to be maintained, this would still not be an acceptable as an excuse. One of the adjacent circuit-breakers could have been utilised for the connection – even as a temporary measure. The lack of an OCPD presents a serious risk in the event of a fault occurring on the circuit, therefore, the appropriate classification code would be a C2, Potentially dangerous – urgent remedial action is necessary.

SAFE ISOLATION AND BORROWED NEUTRALS This article highlights the dangers associated with borrowed neutrals in electrical installations, best practices for safe isolation and measures to mitigate such risk, while ensuring compliance with statutory requirements and the recommendations of BS 7671.

energisation of a final circuit that in such circumstances is intended to be isolated.

hose planning to isolate a final circuit safely will generally approach the task assuming that the circuit has been correctly wired. However, this assumption can pose serious risks where the neutral conductor is unknowingly shared with another final circuit. This condition is sometimes called a borrowed neutral.

Compliance with statutory requirements and BS 7671 One of the most potentially dangerous errors an installer can make is to ‘share’ a neutral between several circuits. The term ‘borrowed neutral’ is a misnomer. More accurately, the neutral is being ‘shared’ or crossed, particularly in the case of adjacent ring final circuits. Any circuit in which the neutral conductor is shared across final circuits without appropriate design and means of disconnection does not meet the requirements of BS 7671. NICEIC assessors occasionally find cases where a neutral conductor from an upstairs lighting circuit is ‘borrowed’ for a ground floor staircase luminaire or vice-versa. Similarly, where the wiring of two radial circuits supplying socket-outlets is installed in the same containment such as trunking or conduit system, a neutral conductor is occasionally found to be ‘shared’ between circuits.

Fig 1 – Typical shared neutral condition

Fig 1 shows a diagrammatic representation of a typical borrowed neutral condition. Compliance with the Electricity at Work Regulations 1989 is a legal requirement. The presence of shared neutrals could be seen as a breach of Regulation 14 if a live conductor is inadvertently contacted. The regulations emphasise the importance of treating all conductors, including neutral conductors, as live until proven otherwise. Regulations 314.4 and 521.8.2 of BS 7671 recognise that each final circuit must be connected to a separate way in a distribution board or consumer unit, and that the line and neutral conductors shall be electrically separate from that of every other final circuit. This requirement is essential to prevent the indirect

The risks associated with shared neutrals Contractors should be aware of the dangers shared neutrals pose to electrically skilled operatives working on the installation. Since neutral conductors are defined in Part 2 of BS 7671 as a live part that is intended to be energised and carry a current during normal use, an unsuspecting operative may be inadvertently exposed to such a live conductor even after performing isolation. Borrowed neutrals create a risk of electric shock or electrical burns for any operative carrying out maintenance or other installation alteration or extension work in the future. There have been incidents where an operative has isolated what is believed to be a safe circuit, tested for voltage and confirmed the circuit was dead. However, when the neutral conductor was disconnected, it was revealed to be shared with another live circuit, leading to an electric shock and/or burns. This situation is represented in Fig 2, where a neutral conductor can remain live due to a shared neutral. Although circuit a) has been ‘de-energised’, if the neutral conductor of that circuit was disconnected, it will be at a potential of 230 V with respect to earth, making it just as hazardous as a live conductor.

THE CPD ZONE

As shown in Fig 3, a line conductor can remain live even after switching off and isolating the circuit, due to the presence of a shared neutral. Although circuit b) in this case has been ‘de-energised’, the line conductor of that circuit is still at a potential of 230 V with respect to earth. Inspection testing and reporting of shared neutrals A shared neutral discovered during periodic inspection and testing of an installation is a potentially dangerous non-compliance and would warrant a classification code C2 being recorded in the Electrical Installation Condition Report. In such cases, the client should be advised of the danger that this defect presents to those working on the circuit and what remedial action is necessary to rectify the issue. Provided the client agrees, the faulty circuit should be isolated and secured in the ‘off’ position and an advisory notice posted until the fault has been remedied. Further guidance on the use of classification codes can be found in the Electrical Safety First’s Best Practice Guide 4, Electrical Installation Condition Reporting for domestic and similar installation, which can be downloaded free-of-charge from the Electrical Safety First’s website: electricalsafetyfirst.org.uk/professional-r esources/best-practiceguides. Making safe The neutral conductor is by definition a live conductor. Consequently, the neutral should always be treated as live until it is securely isolated, proved to be dead and precautions taken to prevent it becoming live. Regulation 14 (Work on or near live conductors) and Regulation 13 (precautions for work on equipment made dead) of the Electricity at Work Regulations 1989 refer. Best practices for safe isolation Within the Electricity at Work Regulations 1989, both Regulation 13 and Regulation 14 emphasise the importance of treating neutral conductors as live until proven otherwise. To ensure complete isolation: ● Confirm it’s safe and acceptable with the occupier/user to perform isolation.

● Identify a suitable point of isolation, where the isolator is off-load, remove load first. ● Confirm the voltage indicator device is working correctly against a known source or proving unit. ● Confirm the presence of voltage where the installation is already energised. ● Switch off or open the selected means of isolation. ● Confirm the absence of voltage at the outgoing side of the means of isolation

and test for voltage between: ● Line to Earth ● Line to Neutral ● Neutral to Earth ● Re-conﬁrm voltage detection indicator by conﬁrming functionality against a proving unit or a known source of supply. ● Lock off or otherwise secure the means of isolation for the circuit. ● Place warning notices to the lockout device to indicate that work is in progress.

037_PE_OCT26_Layout 1 31/08/2026 17:12 Page 39

Where unexpected voltage is detected, all circuits should be retested after investigating for a shared neutral condition and isolation procedures reconfirmed before proceeding. In a single-source installation, it may be appropriate to switch off the main double-pole isolation switch at the consumer unit to disconnect all final circuits. In complex installations with multiple distribution boards or sources of supply, more thorough procedures must be followed to ensure complete de-energisation. Certsure has produced a safe isolation pocket guide in the NICEIC App that allows electricians to access this important information while they’re working. The NICEIC App is available from the App store for iPhone and iPad and Google Play for Android phones and tablets.

Correcting shared neutral issues Where a shared neutral is found in a circuit requiring alteration or extension, the issue must be rectified before any modifications can proceed and before issuing certification for the new work. The most effective correction action, but not always the simplest approach, is to install a dedicated neutral conductor from the distribution board to the affected circuit, while ensuring the necessary requirements of BS 7671 are met. Summary Shared neutrals present a significant safety hazard in electrical installations. They create the risk of unexpected energisation of circuits, leading to a potential of electric shock and/or a fatal incident.

To meet the requirements of both the Electricity at Work Regulations 1989 and those of BS 7671, electrical contractors must ensure that each final circuit is protected by a single overcurrent protective device and that each circuit has its own neutral conductor while remaining electrically independent from that of any other circuit. To eliminate any such dangers, proper inspection, testing and reporting must be carried out, including the implementation of any corrective action where necessary. When working on electrical systems, contractors must always follow safe isolation procedures, treat neutral conductors as live until proven otherwise and where necessary, rectify any instances of shared or crossed neutrals before proceeding with any modifications or extensions.

THE HIDDEN DANGERS OF RADON In this article, the experts at Aico explore the dangers of radon, the strategies that housing providers are using to manage it, and the regulatory drivers that they need to be aware of.

ost people go through their lives without thinking about radon. This noble gas is invisible, it has no smell, and you would not notice it in a room. But did you know that, each year, it’s estimated to cause 1,100 deaths across the UK? For context, this is equivalent to about two-thirds of the number of people killed on roads in Great Britain during 2025. With growing awareness around this silent killer, and increased regulatory scrutiny, housing providers are coming under increasing pressure to have a strategy in place for managing radon.

An invisible killer Radon is a radioactive gas that occurs naturally in the ground. It’s produced as small amounts of uranium naturally decay in bedrock, especially granite or shale. Because of this, radon levels vary greatly across the country. Housing providers can

get a rough view of how much radon is at a property using UKHSA’s radon map or order a survey for more details. Radon naturally accumulates in homes, especially in winter months when rising air from heating draws it out of the ground and closed windows keep it trapped indoors. You won’t immediately notice high concentrations of radon, but over time they can increase the risk of lung cancer. In fact, Cancer Research UK estimates that 5% of lung cancers in the UK are linked to exposure to radon. This risk is significantly higher for people who smoke. The average radon level in UK homes is around 20 Bq/m³ (Becquerels per cubic metre). The UKHSA has set out an Action Level of 200 Bq/m³, above which it recommends that radon levels at a property should be reduced. It also sets out a Target Level of 100 Bq/m³ for remediation and preventative work. If radon levels are below the Action Level but above the Target Level, remediation should be considered.

How are housing providers managing radon? As radon is invisible and odourless, detection and monitoring systems are needed to check radon levels against these thresholds. There are two common ways of doing this. The first is the use of single-use radon detectors. These can be installed in homes in areas identified as being at high risk from radon, left for three months, then removed and sent to a certified lab for testing. This provides an accurate reading of average radon levels at a property over this period. Another option is a continuous radon monitor, which can be installed at a property and gives continuous readings over time. These readings can then be used to determine the average level of radon at a property. This reduces the need for contractor visits and multiple single-use detector and gives increased visibility of seasonal changes. As a result, they’re seeing increased adoption in the UK and across the globe.

THE CPD ZONE

However, when using a continuous radon monitor, housing providers should be careful about which sensors they use. Consumer-grade systems may not always provide the detail, reliability and accuracy of higher-end sensors. Where a landlord identifies a high level of radon at a property, they then need to take the necessary measures to reduce it. The most common option is a radon sump – a system that uses a fan to extract radon from under the building, but other forms of ventilation are also sometimes used. Looking towards Awaab’s Law Radon falls within the Radiation hazard under the HHSRS (Housing Health and Safety Rating System). Because of this, it will be covered by Phase 3 of Awaab’s Law in England. This is currently expected to come into force in 2027. Awaab’s Law requires that social landlords investigate and repair hazards which fall under the regulation within tight timeframes. Phase 1 of this regulation currently covers damp and mould, as well as emergency hazards, and many housing providers have faced a very large number of disrepair cases since the regulation came into force, which has put signiﬁcant strain on their resources. Many social landlords are now using environmental monitoring systems like Aico’s HomeLINK technology to identify high-risk properties and carry out pre-emptive maintenance during summer in order to reduce the strain during winter. While radon is not as immediately

“Where a landlord identifies a high level of radon at a property, they need to take the measures to reduce it.” apparent as damp and mould, information on risk levels is publicly available and consumer air quality sensors are increasingly common in the UK. A robust, proactive way to identify high-risk properties will be crucial going forward. There is also the question of how to monitor the effectiveness of any interventions at the property. Awaab’s Law requires that housing providers take the necessary steps to make the property safe and prevent recurrence, which means demonstrating that these measures have been effective. This typically means retesting properties with a separate single-use detector after they have installed a sump. The benefits of continuous monitoring As the way that housing providers manage radon continues to evolve, continuous monitoring looks to provide a valuable complement to traditional testing methods. Rather than providing a snapshot of radon levels over a ﬁxed testing period, continuous monitors can provide greater visibility of how levels change over time, including the impact of seasonal and environmental factors.

PROFESSIONAL ELECTRICIAN

For social housing providers, this additional insight could help identify properties that may require further investigation, support more informed decisions around remediation, and provide an ongoing way to assess whether interventions have been effective. For example, where mitigation measures such as a radon sump have been installed, continuous monitoring can help landlords track changes in radon levels over time and understand whether the intervention is having the intended beneﬁt at the property. Continuous monitoring can also reduce the need for repeated contractor visits and the installation and removal of multiple single-use detectors, helping housing providers take a more proactive approach to managing radon across their housing stock. With increasing awareness of the risks associated with radon and greater regulatory focus on how housing providers identify and manage hazards, having reliable and accurate information about radon levels will become increasingly important. Continuous monitoring has the potential to play an important role in helping landlords move from periodic testing towards a more informed, proactive approach to radon management.

AMD 4: PROTECTED ESCAPE ROUTES AND FAULT CURRENT PROTECTION

Although there have been many pieces written about the general changes introduced by Amendment 4 of BS 7671, this article from the experts at Unicrimp will consider in more detail two specific changes around protected escape routes and the position of devices for protection against fault current, and their likely implications.

Protected escape routes The changes to the requirements of Section 422 introduced in 2018, and further changed in a subsequent corrigenda, has now been further amended to provide greater clarity on the specific locations where the requirements of Section 422 apply. The updated Regulation 422.2.201 now details the specific locations where cables or electrical equipment must not be installed. These locations are now limited to fire-fighting shafts and protected stairways. A fire-fighting shaft comprises a firefighting stairway and, where relevant, a firefighting lobby. That same regulation now details the types of cables permitted in protected corridors. Regulation 422.2.1 details the following permitted cables: ● Fire-resistant cable meeting the requirements of Regulation 560.8.1. These are:

46 October 2026

PROFESSIONAL ELECTRICIAN

● MI cable systems conforming to BS EN 60702-1 and 2 and BS EN 60332-1-2; ● Fire-resistant cables conforming to IEC 60331-1, 2 and 3 and with BS EN 60332-1-2; ● Fire-resistant cables complying with test requirements of BS EN 50200, BS 8434 or BS 8491, appropriate for the cable size and with BS EN 60332-1-2; ● A wiring system maintaining the necessary fire and mechanical protections. ● Bunched cables with resistance to flame propagation according to the requirements of the relevant parts of BS EN 60332-3 series, or ● Single wires or cables, where cable management systems according to indents d) to g) in Regulation 422.2.1 are used, tested to BS EN 60332-1-2. These cables are to be of limited smoke production and shall have limited halogen acid gas content not exceeding 0.5% when tested in accordance with BS EN 60754-1. Where single-core wires or cables are referenced, indents d) to g) cover: ● Non-flame propagating conduit systems conforming to BS EN 61386. ● Non-flame propagating cable trunking and ducting systems conforming to BS EN 50085. ● Non-flame propagating cable tray and ladder systems conforming to BS EN 61537. ● Powertrack systems conforming to BS EN 61534.

046_PE_OCT26_Layout 1 31/08/2026 17:29 Page 47

Note 2 states that ferrous metal (steel) is deemed to be an example of a material having limited smoke production. Designers should continue to ensure that care is taken in limiting the type and nature of cables and cable management systems where they are to be installed in protected escape routes. Position of devices for protection against fault current Section 434 in BS 7671 covers Protection against fault current. Within that overall section, Regulation Group 434.2 covers where protective devices should be provided to provide protection against fault current. The general requirement states that: ‘…protection against fault current shall be installed at the point where a reduction in the cross-sectional area or other change causes a reduction in the current-carrying capacity of the conductors, except where Regulation 434.2.1, 434.2.2 or 434.3 applies.’ This general regulation, therefore, provides clear requirements that show where protection against fault current must be applied (see Fig 1). However, where a location does not present either a fire risk or an explosion risk, Regulations

Fig 2 – Scolmore Click connector block

434.2.1, 434.2.2 and 434.3 do permit some variation on this requirement. Regulation 434.2.1 allows for the position of the protective device to be varied from that detailed in Regulation 434.2 under specific conditions. These conditions are: ● that the conductor must not exceed 3 m; and ● be selected and erected to be inherently short-circuit proof and earth fault proof; and ● be installed in such a manner as to reduce to a minimum the risk of fire or danger to persons. All of the three conditions must be met for compliance. BS 7671 defines ‘Inherently short-circuit and earth fault proof as: ‘The state of electrical equipment or

Fig 1 – Examples of where a protective device may need to be installed

assembly protected against short-circuits and earth faults due to design and erection provisions.’ The second condition of 434.2.1, requiring the conductor to be inherently short-circuit proof and earth fault proof, is a change from that which previously existed; i.e. requiring the cable to be installed in such a manner as to reduce the risk of fault to a minimum. This change is more absolute and requires the installer to take such additional measures to ensure the inherently short-circuit and earth fault proof requirement is met. How this requirement is met is not detailed in the standard, and it is for the installer to decide on the way(s) in which the requirement is met. By way of example, consider a condition where two supplies are required, one for a consumer unit and one for an EV charger. The consumer unit is supplied with meter tails having a cross-sectional area of 25 mm2, the EV charger circuit has tails having a cross-sectional area of 6 mm2. A connector block (see Fig 2) is used to supply both circuits. Since a smaller cable is being used for the supply of the EV charger, Regulation 434.2 applies and a protective device must be installed at the point of change in the current-carrying capacity of the cable. However, where there is no fire or explosion risk, Regulation 434.2.1 may be used to alter the point at which the protective device is installed if it meets the three specific conditions detailed. Conclusion There have been many changes made to BS 7671 in Amendment 4. Subsequent articles will consider in further detail the implication of further changes.

Steve Humphreys, Technical Commercial Manager at NAPIT, outlines the key changes in BS 7671:2018+A4:2026, including the new Chapter 57 on stationary secondary batteries and what installers must consider when selecting, locating and safely installing modern energy storage systems.

S 7671:2018+A4:2026 has introduced a brand-new chapter on stationary secondary batteries. The new Chapter 57 covers the requirements for stationary secondary battery installations designed to store and supply electrical installations. The Chapter contains the following sub-sections:

● Scope (570.1) ● Main Characteristics of Batteries (570.5) ● Selection and Erection of Electrical Equipment (570.6) Let’s look at the specific requirements of each sub-section of this new Chapter and how they apply in practice when installing electrical energy storage systems. Scope The scope of Chapter 57 sets out the requirements for stationary secondary battery installations that are intended to operate as a source of supply for

electrical installations. This includes systems designed to store electrical energy and release it when needed, forming an increasingly important part of modern energy management and backup arrangements. Stationary secondary batteries are rechargeable batteries used in energy storage systems located in fixed positions such as homes and businesses, as shown in Fig 1. The Chapter does not apply to primary batteries – non-rechargeable types – incorporated into products and systems such as fire alarms, security alarms and emergency lighting. Main characteristics of batteries The type and capacity of the battery selected must take into account any other local generation, such as solar PV, including coupling modes and the connection of power conversion equipment (PCE), i.e. inverters. The PCE with secondary batteries may be incorporated into an ‘all-in-one’ or

packaged system. An electrical energy management system (EEMS) is used to control the energy flow of the batteries through the PCE into the electrical installation. This may also be incorporated into a packaged system or, if part of a bespoke system, the EEMS must be compatible with the batteries and other associated equipment. Whether it forms part of an ‘all-in-one’ system or is separate to the inverter, a stationary secondary battery is the source of energy that will supply power to essential loads. The battery comprises a number of cells, wired in series and parallel, housed within a casing to create a battery module. These modules can then be combined to form battery racks. The designer will need to consider the following when selecting the type of battery: ● Suitable battery chemistry for the energy storage system’s location and usage ● Load demand of the electrical installation

PROFESSIONAL ELECTRICIAN October 2026 49

049_PE_OCT26_Layout 1 31/08/2026 17:34 Page 50

THE CPD ZONE means of separate windings of a transformer; or ● The PCE does not require a Type B RCD as stated by the manufacturer. Regulation 570.6.8.201 states that a warning notice, see Fig 2, indicating the presence and location of a stationary secondary battery system, shall be ﬁxed:

● External influences ● Battery charging and discharging times/profiles ● Battery voltages Selection and erection of electrical equipment Battery Standards are guidelines and specifications that ensure the safety, performance, compatibility and quality of batteries. Stationary secondary battery installations shall conform to the relevant parts of the BS EN IEC 62485 series. These Standards are developed by international and national organisations to regulate the design, manufacturing, testing and use of batteries in different applications. The selection and erection of secondary batteries is something only skilled and competent persons should undertake. As we are dealing with direct current (DC), this may be outside of the skillset of a traditional electrical contractor. This requires strict control measures. Live parts of batteries, cells and other connections shall only be accessible to skilled and/or instructed persons. Suitable basic protection shall be provided by insulation or enclosures so that conductive parts, such as the battery terminals, cannot be touched. Regulation 570.6.2.2 provides the requirements where an RCD is used for automatic disconnection of the AC supply circuit. It states that a Type B RCD shall be used unless:

(a) At the origin of each electrical installation; (b) At each metering position, if remote from the origin; (c) At each consumer unit or distribution board to which a supply from a stationary secondary battery is connected. Location of stationary secondary batteries The location of stationary batteries is one of the most important considerations when installing energy storage systems. Regulation 570.6.7.203 requires that stationary secondary batteries in dwellings be installed in a suitable location, taking account of PAS 63100. In other premises, the location of storage batteries and ﬁre protection requirements shall be selected with regard to the ﬁre strategy for the premises. PAS 63100 was published in March 2024 to provide clear guidance on selecting suitable locations for stationary secondary batteries and other equipment such as

● The PCE provides at least simple separation between the AC and DC side of the system; ● At least simple separation is provided between the PCE and the RCD by

inverters. It offers practical guidance that supports consistent decision-making on-site. PAS 63100 aims to help installers manage fire-safety-related hazards associated with battery storage systems in homes within the UK. Its provisions are intended to reduce the risk of batteries becoming a source of ignition and to limit the impact of a battery fire should one occur. While battery fires are, at the time of writing, low in frequency, they can have a high impact due to their behaviour in fire. As some batteries can exhibit focussed jet-like flaming, a higher degree of fire compartmentation should be considered. Where practicable, stationary secondary batteries shall be installed outdoors, with a minimum IP rating of IP65, as shown in Fig 3. Batteries installed outside shall not be installed within 1 metre of escape routes, doors, windows and ventilation ports, including soffit vents. Where it is not practicable to locate batteries outdoors, they must not be located in the following locations: ● Lofts and roof spaces ● Rooms intended for sleeping ● Escape routes The risks associated with installing batteries in locations such as loft spaces are well recognised.

049_PE_OCT26_Layout 1 31/08/2026 17:35 Page 51

speciﬁcation offers detailed guidance for designers and installers of batteries and related equipment. As battery technologies advance and energy storage becomes more common, clear and authoritative requirements are increasingly important.

These include: ● Challenges in transporting equipment into the loft, including manual handling risks ● Limited access for inspection and maintenance ● Increased risk of overheating due to poor ventilation ● Excessive weight placed on ceiling joists ● Elevated ﬁre risk due to presence of stored combustible materials (e.g. cardboard boxes) PAS 63100 doesn’t specify any particular restrictions regarding the location of the inverter or other associated equipment, other than those applying to batteries. These points underline the need to choose installation locations that maintain safety. However, equipment installed in infrequently accessed rooms will require interlinked ﬁre detection, as shown in Fig 4. This section also outlines the requirements for protection against electric shock, protection against fault current on the DC side, protection against thermal

effects, the risk of arcing and isolation. Conclusion This is a very welcome Chapter within BS 7671, providing clarity and requirements so that secondary batteries and associated equipment are installed safely and correctly. The Amendment 4 reference to PAS 63100 is also a valuable addition, as this

KIMMY STOPS THE CLOCK AS ELEX VISIT PROVES TO BE PERFECT TIMING

n on-the-job wiring headache turned into a double victory for a 30-year-old electrician during a visit to the Forum Lighting Solutions stand at ELEX earlier this year. Not only did Kimmy The Sparks – who works in the London and Essex areas – walk away with a £100 Amazon voucher for winning the popular ‘Stop the Clock’ challenge, but she also discovered the exact technical solution needed to solve a complex residential installation project. Faced with a tricky project on-site,

Kimmy had been searching for an efficient alternative to traditional cabling. The brief required her to ﬁnd a way to switch outdoor lights from inside a client’s living room, without routing new cables or drilling through to the garage consumer unit. While testing her speed on the Forum stand at the Exeter and Harrogate ELEX events, Kimmy discussed the problem with the Forum technical team. They introduced her to the Forum Kinetic wireless switch range, which provided the ideal wireless solution to bypass the garage entirely.

“I had a very specific job I needed a solution for and ended up finding it right there on the stand,” Kimmy explained. “I needed to switch outdoor lights from inside the living room without going into the garage and without running a new cable. Forum’s products are innovative, professional, and come with clean, clear instructions.” Kimmy praised the on-stand expertise that helped resolve her installation dilemma, stating: “The team were brilliant – a good laugh yet informative. A special mention must go to Collin, who had all the answers to my questions! “Winning the voucher was amazing and unexpected – a pleasant surprise after I got back into the work routine.” Her success at the exhibition caps off a determined 12-year career journey in the electrical sector. Kimmy transitioned into the trade in 2014 from an administrative and accounts role at a building firm “It actually started as a joke,” Kimmy recalls. "Everyone in the office laughed and said: ‘stick to your high heels and office desk - you’re a woman’. “That ignited a fire to prove them wrong, as well as society on a wider scale. I started going out on the tools doing evening emergency call-outs after my office job, and things progressed from there.” Forum Lighting Solutions is just one of a huge number of brands at this month’s Stoneleigh Park ELEX show that might have the solution to your on-site headache. You’ll have the opportunity to see and engage with them all, up close and personal, on October 22nd & 23rd.

You ask: I PURCHASED AN ENTRY-LEVEL THERMAL CAMERA AND I LOVE IT, BUT I'M FINDING ITS RESOLUTION LIMITING ON BIGGER COMMERCIAL JOBS WHERE IT CAN BE DIFFICULT OR DANGEROUS TO GET CLOSE TO THE EQUIPMENT I’M INSPECTING. WHAT'S THE NEXT STEP UP?

Megger says: Your entry-level thermal camera probably has a resolution of around 120 x 90, which is ﬁne when you can get close to the equipment you’re inspecting. On bigger installations where you need to work at a greater distance, you’ll ﬁnd a camera with higher resolution is more suitable. We recommend the Megger TC256 which has a resolution of 256 x 192 and incorporates a built-in laser pointer that helps with accurate targeting over larger distances. The TC256 also has a NETD of just 45 mK which means it can see very small temperature differences, making it easier to spot early-stage faults. It offers multiple display modes – infra-red, visible light, picture-in-picture and fusion mode – so you always get results that are accurate and easy to interpret. Additionally, images and videos from the TC256 can easily be transferred to a PC via a USB connection.

CABLES & CABLE MANAGEMENT

BEST OF BOTH WORLDS With customers increasingly demanding installations that are both quick and attractive, Ian Hunter, Luceco Trade Director, looks at how innovative cable management can ensure that you don’t have to compromise on either.

he popularity of indoor surface-mounted cabling and the growing demand for residential EV chargers on outdoor walls may seem worlds apart, but both share a common requirement: customers want solutions that are quick to install and look great. Whereas those two wishes used to seem incompatible: ‘Sorry, we cannot do both’ or ‘Take-your-pick’, D-Line’s innovative solutions provide a perfect answer to satisfy these popular requests. It’s been twenty years since D-Line trunking was launched in the UK, to provide a long-overdue alternative to either channelling walls, or using ‘unfashionable’ bog-standard products that hadn’t evolved since the 1950s.

Now D-Line’s range – including ½-round and ¼-round profiles with latching lids – is used every day around the world for routing surface-mounted cables, especially in projects where time, safety and appearance matter. Whilst customers love the subtle appearance, installers appreciate the one-piece design and push-fit accessories. What both will agree on, however, is that D-Line’s products make surface installations look attractive. Staying consistent to its design-led ethos, D-Line was also first to develop fire-rated fixings for PVC trunking, conduit and direct-to-surface cables. While providing peace-of-mind compliance with the essential safety requirements of the 18th Edition, these solutions also meet the ‘quick install, look great’ expectations of customers in mature markets seeking added value. Streamlined, quality finish In D-Line’s Safe-D range you’ll find wrap-and-lock designs. These steel fasteners, tested for BS 7671 compliance, are perfect for surface-mounted conduits, with options for EV-charger cables too. Indeed, the collection of black, white, and galvanised 20 mm and 25 mm saddles are ideal for conduit installations. For EV charger cables, black-colour options are available in three sizes, allowing installers to adjust between 10-17 mm

cable, 16-21 mm, and 22-26 mm diameters. Using D-Line wrap-and-lock clips creates a streamlined finish, with the anchor screw neatly concealed. Customers benefit from the quality of the finish, while installers can halve the installation time per clip. At a labour rate of £45 per hour, saving just 30 seconds per clip equates to £0.90 per clip compared with three-screw saddles or more industrial-looking cleats. It’s a better-looking, more efficient job all round. So, is the future in good hands? We’ll leave Paul Ruddick, D-Line founder, to provide the final word on that one: “Since joining Luceco Group in 2024, it’s been fantastic for D-Line products to complement various Luceco innovations. “We’ll soon be sharing some other exciting product developments that combine speed, safety and style considerations for surface-mounted cable management. These will continue to evolve and improve on what can be achieved in conduit installations, so watch this space!” BROWSE THE FULL RANGE OF CABLE MANAGEMENT SOLUTIONS FROM D-LINE BY VISITING: WWW.RDR.LINK/ECC020

CABLES & CABLE MANAGEMENT Correct speciﬁcation of cable tray systems is essential to ensure they’re suited to the demands of the application. Terry Adams, Technical Manager at Marshall-Tufflex highlights the product features to look out for.

TRAY BIEN!

able trays are a widely used solution, offering simple routing and support of power and data cables. They allow cables to be easily added or removed, and perforated designs promote airﬂow and help to prevent overheating of cables. However, choosing the correct cable tray is essential to ensure the system performs effectively throughout its lifespan and complies with the IET Wiring Regulations.

Choosing the right material One of the ﬁrst considerations for installers is selecting the right material for the cable tray with options including metal, PVC or GRP (Glass Reinforced Polyester). For interior installations, such as warehouses, it is recommended to use metal cable trays made from pre-galvanised steel as they’re strong and simple to install, especially if you choose systems that interconnect without the need for separate couplers. In the case of more demanding applications such as water treatment plants, where metal cable trays cannot be used due to risk of corrosion, PVC cable trays are ideal. Additionally, the PVC tray is lightweight and easy to work with, reducing time spent on-site.

60 October 2026

GRP cable tray is best suited for aggressive outdoor applications, where the cable management will be exposed to more harsh conditions. Also, lightweight and easy to handle, GRP products are highly corrosion and UV resistant, can withstand contact with many common chemicals and have an extremely wide operating range of -80ºC and 130ºC. For projects within the rail sector and other transport infrastructure environments, installers should also consider whether the manufacturer holds RISQS veriﬁcation, helping to demonstrate Metal Cable Tray compliance with industry procurement and supplier assurance requirements. Checking loading capacities Cable management systems can often become PVC Cable Tray overloaded, either during the initial installation or when additional cables are added, which can increase the risk of tray deﬂection, damage or failure. Therefore, it’s essential for contractors to specify the correct cable tray GRP Cable Tray to avoid this. Calculations based on the cable manufacturer’s data and the tray’s safe working load should inform product selection. It’s advisable to choose a tray with greater capacity than currently required to future-proof the installation and reduce long-term costs for clients.

PROFESSIONAL ELECTRICIAN

Following fire safety requirements During a fire, if the cable management fails because of the heat, the cables can present a serious hazard to those evacuating as well as the firefighters attempting to gain access. Therefore, it’s important to ensure the cable support system is installed in accordance with the requirements of the 18th Edition Wiring Regulations. Regulation 521.10.202 requires cables to be adequately supported using non-combustible fixings to prevent premature collapse in the event of a fire. Due to their high melting point, steel cable trays are the ideal solution. Cable retention clips, such as Linian's cable tray clips, can help secure cables in place, particularly in the event of a fire. For products with a lower melting point, such as PVC, the cable must be fixed to the structure of the building using fixings that won’t disintegrate in fire. Installers should also refer to the BEAMA guidance on this topic to ensure the installation is compliant. As you can see, correctly specifying and installing the system is essential for long-term performance, safety and compliance. Expert technical advice, including specialist cable management support from manufacturers such as Marshall-Tufflex, can also help ensure a safe, professional finish.

CABLES & CABLE MANAGEMENT

ACCESS all areas

hen installing an access control system, attention is often focused on the visible hardware such as readers, controllers, locks and power supplies. However, the cabling connecting these components is just as important. Selecting the wrong cable can result in voltage drop, unreliable equipment, communication issues and unnecessary troubleshooting, as well as costly return visits to site. Understanding the application and selecting the appropriate cable from the beginning can help installers deliver a more reliable and trouble-free installation. Cable for ancillary devices One of the most common choices is between Copper Clad Aluminium (CCA) and full copper multicore cable.

Abbie Molesworth, responsible for Access Control Technical Sales at Door Controls Direct, offers some pointers on how to select the right access control cabling.

Both can be suitable for ancillary devices, however they’re not necessarily the most appropriate choice for every device. Controllers and readers may have speciﬁc cabling requirements, so installers should always refer to the manufacturer's recommendations. CCA can provide a cost-effective option for suitable low-current applications and shorter cable runs, while full copper offers better conductivity and lower resistance. This makes full copper particularly useful where voltage is important, such as when powering maglocks and electric strikes over longer cable runs.

equipment, motors, machinery and power cables can introduce electromagnetic interference, potentially affecting sensitive signals. Screened multicore cable can provide protection where this is a concern. The foil screen reduces electrical noise and signal interference, helping maintain signal clarity and performance between readers and controllers.

Installer tip: Always consider the device's current consumption, cable length and acceptable voltage drop.

Think about the future Good cable selection isn't simply about meeting today's site requirements. Instead, installers should also consider how the set-up may develop over time. Systems may be changed or upgraded with additional components such as intercoms, CCTV or other network-connected devices added later. Installing suitable network infrastructure at the start can make future upgrades easier and reduce labour and disruption. Ultimately, there’s no single cable suitable for every access control set-up. The correct choice depends on the equipment, current requirements, cable distance, environment and potential future needs. Taking the time to select the right cable at the design stage can help improve system reliability, reduce potential faults and provide an installation that’s ready to adapt as technology evolves.

Network cable As access control set-ups increasingly move towards IP and network-based technology, Ethernet cabling is becoming an important part of many installations, including door entry systems and networked controllers. Cat5e remains versatile and a cost-effective option for many network applications, while Cat6 provides greater bandwidth and additional performance capability, making it a suitable choice for new systems where increased network capacity or future expansion is likely. Installer tip: Check the manufacturer's requirements and consider future upgrades to ensure the correct network cable is chosen from the start. Consider the environment The installation environment should also inﬂuence cable selection. Electrical

Installer tip: Always make sure the cable selected is suitable for the environment in which it will be installed, as there are many different cable types.

KEEPING IT

REEL

How do you choose the right cable reel for your particular requirements? Mark Lingard, Marketing Manager at CEENorm UK – home of the Cablecaddy brand – offers some pointers.

etractable cable reels are particularly popular because they provide a ﬂexible power solution to users – the power is there when you need it, or it’s stored away when you don’t. One of the main driving forces behind the adoption of cable reels is the focus on health and safety in the workplace. With ceiling and wall-mounted reels available, cable reels mean permanently wired, yet ﬂexible power, is available without any trip hazards. Easily accessible and safe From a health and safety point of view, ceiling-mounted cable reels offer ‘drop-down power’ when it’s needed, easily accessible and safe within the workspace – with the addition of a product like a Combi-Cube allowing multiple sockets to be available. Combi-Cubes are suspendable multi-socket outlets ideal for use in factories, garages, workshops, production facilities, offices, education establishments and more – offering a simple yet effective way of proving drop-down power when needed. The Marcaddy Combi-Cubes are designed to be used with a spring-return cable reel, which allows the user to simply pull down the power supply when needed. The Combi-Cube series ranges from 110 V to 230 V, 13 A and 16 A, with either two or four sockets, and come with high-quality Bals plugs built-in as standard.

How to get the right cable reel for you When requesting an industrial cable reel from Cablecaddy, the ﬁrst thing we’ll need to know is what sort of reel is required. Is this a power reel, a grounding/earthing reel, a data transmission reel, or an EV charging cable extension reel? For a power reel, we then need to know the cable type (H05 – PVC, or H07 – rubber). Rubber cable is harder wearing, so the intended application/environment in which the cable will be used should guide the decision as to which option you choose. We’ll also need to know the number of cores, and the required cable length (in metres). The minimum cable length we can offer is 3 m, while the maximum is 55 m. Each cable reel series has a minimum and maximum cable length, so if you advise what you’re looking for, we’ll be

able to narrow down your options. We’ll then need the required rating (in Amps if possible. The figure you provide needs to be for the fully unwound cable, as well as the required operating voltage. The rating for the unwound cable is always higher than when wound, which is why we need the rating for the unwound cable. kW is okay if you don’t know the figure in Amps. Next we need to know where the cable reel is going and what sort of environment it will be used in. We can offer IP42, IP43 and IP65, so let us know the preferred IP rating. Additionally, how are you mounting the reel? Wall? Ceiling? Or do you have something else in mind? And, let us know what the reel is going to be used for. This allows us to be more certain that the cable reel we’re advising for you is the correct specification for the job. Finally, if you’re looking for an EV charging cable extension reel, we simply need to know the car vehicle charger type – 1 or 2. The wall type will always be type 2. Our cable reels are available through all major UK electrical wholesalers.

CABLES & CABLE MANAGEMENT

A MATTER OF TIME

iwa has continued to respond to evolving requirements for fire safety in high-rise residential buildings with the introduction of the world’s first certified 180-minute fire resistance test for cables. The new prolonged burn test, as part of BASEC Certificate of Assessed Design (CAD058), goes beyond the 30, 60 and 120-minute benchmarks which form the basis of current standards for fire-resistant cables. Kiwa’s BASEC business unit conducts independent tests at its own laboratories, with the CAD providing assurance to all those involved in fire systems specification and management that the product still performs as expected – even after 180 minutes’ exposure to fire. The current standards for 30, 60 and 120-minute fire-resistant cables have underpinned the design of life safety systems for many years. They still govern the design of systems such as fire detection and alarm systems, emergency lighting, emergency voice communication, smoke extraction and pressurisation systems, and firefighting infrastructure. However, these standards date from times when occupancy levels in high-rise buildings were generally lower. Meanwhile, the quantity of buildings exceeding 150 metres in height is rising rapidly, meaning more intense requirements

around safety and evacuation, with more people needing to exit the building and having to cover more distance to do so. These greater physical heights and higher occupancy rates place greater demands on the systems designed to protect occupants against the risks posed by fire. All of this means the role of interconnected active fire safety systems has never been more prominent. Should a fire break out, the integrity of circuits – and therefore the cables that connect critical fire safety elements – is vital. The longer these cables remain functional, the greater the time available for evacuation and emergency response. Greater stringency in legislation While the minimum fire resistance standards for cables haven’t yet been altered to reflect these changing building risk profiles, at Kiwa we believe it’s only a matter of time given ever greater stringency in legislation and sector-specific regulation. Enacted in 2022 in light of the Grenfell disaster, the Building Safety Act has heightened the role of ‘Accountable Persons’ when it comes to the specification, installation, maintenance and performance of fire mitigation systems within high-rise buildings in the UK. Cables are a particular challenge as they’re hidden away, making maintenance and replacement far more difficult.

James Daniels, Business Unit Manager at Kiwa, examines why the introduction of a new cable fire resistance test will help to further drive safety standards in high-rise buildings. Regulation 38 now mandates that detailed, evidence-based fire safety information, such as photographs and commissioning records, must be supplied at project completion. At the same time, BS 9991:2024 significantly revised the UK’s fire safety code of practice for residential buildings, optimising evacuation procedures and enhancing structural protection, while minimising fire risks in modern residential buildings. Given the tightening regulations, building owners, managers and specifiers are increasingly going beyond current levels of compliance and seeking systems that are proven to perform at the highest level. Sooner rather than later, performance standards in fire resistance for cables will be tightened in line with this. If adopted into BSI standards, CAD058 will be the force behind an effective tripling of circuit integrity performance, providing even greater resilience in buildings where firefighting may take place over an extended period, and evacuation may also need to be staged.

CABLES & CABLE MANAGEMENT

What happens when pre-galvanised cable ladders are subjected to extreme fault conditions? Mark Williams, Lead Marketing Manager for Legrand’s cable management portfolio, explains why rigorous testing is more important than ever.

t Legrand UK & Ireland, we’ve demonstrated the exceptional performance of our latest Swifts pre‑galvanised cable ladder range through a comprehensive series of short‑circuit tests in partnership with CMP Products. The tests will offer building operators in high traffic buildings, such as data centres, peace-of-mind that their cable management is sufficiently robust to withstand various short-circuit scenarios that could otherwise risk signiﬁcant downtime.

Extensive testing Working closely with CMP, Legrand undertook extensive testing using CMP’s Patriot, Saturn and Sovereign cleats, installed in both trefoil and quad formation, at fixing centres of 300 mm and 600 mm. Every cleat passed flawlessly, and the new ladders delivered an impressive performance – even under a peak fault current of 190 kA. The reality is, these are punishing tests, designed to replicate the extreme stresses encountered in real‑world installations – especially in environments like data centres, where power demands continue to intensify. Demonstrating that our ladders not only satisfy the requirements of their product standard but also perform reliably alongside critical system components, such as cables, cleats and support structures, gives specifiers and installers real confidence. New construction techniques Legrand launched its pre‑galvanised Swifts ladder range in May 2025. Historically, Swifts ladders have been supplied only in hot dip galvanised or stainless steel, both relying on a welded rung‑to‑siderail construction.

68 October 2026

A STEP AHEAD

Pre‑galvanised steel presents a different challenge – welding it can be messy, hazardous and generally an unpleasant process. To overcome this, our R&D team undertook a detailed evaluation of alternative construction techniques, and we ultimately opted for a ‘clinched’ design. With this design, each rung is secured to the siderail using 50 kN of pressure, creating a strong, reliable joint similar to methods used in automotive manufacturing, where clinching is increasingly replacing traditional welding. Alongside stringent mechanical and performance testing to IEC 61537, we also validated the fire resistance of the new range through DIN 4102‑12 fire testing. Customers have been asking for greater transparency on ﬁre performance, and these tests underline the resilience of the ladders – even under extreme conditions. Perfect partners Swifts ladders have long been used by CMP Products as part of their own validation processes, helping to ensure their cable cleats meet the requirements

PROFESSIONAL ELECTRICIAN

of IEC/BS EN 61914. With the introduction of our new design, we wanted to demonstrate that the pre‑galvanised range can withstand the same severe forces seen during short‑circuit events. With this latest round of testing, Legrand is reinforcing its commitment to both innovation and reliability, proving that the new Swifts pre‑galvanised range is more than ready for the most demanding applications.

This gap between knowing the procedure and following it every time is where accidents happen. These ﬁgures show that electrical incidents and near misses are still far too common on-site and that too many go unreported.

We really want to encourage everyone working around electricity to maintain their awareness of electrical safety procedures and use the resources available to keep their knowledge up-to-date on the latest safety practices and guidance.

t Martindale Electric, we’ve recently published new research showing the true scale of electrical incidents experienced by professionals working with electricity every day. An ‘electrical incident’ or ‘near miss’ includes minor electric shocks, arc events and unexpected energisation. The ﬁndings, based on a survey sent to tens of thousands of electrical contracting professionals, were gathered to better understand real-world experiences of electrical safety, electrical incidents and incident reporting across the industry. Among the key ﬁndings, the survey found that:

is for approved kit (equipment must meet legal safety standards) is for lockout (point of isolation should be identified, locked out and tagged) is for initial prove (voltage indicator should be tested against a proving unit) is for voltage test (electricians must confirm there is no dangerous voltage in the circuit) is for ensure (the voltage indicator must be re-tested against the proving unit before starting work)

Our ALIVE acronym is a simple, ﬁve-step routine that takes the guesswork out of staying safe and we’d encourage every electrical professional to make following it second nature, every single time. The Martindale Electrical Safety in the Workplace Survey 2026 was conducted between June and July 2026 to gather original insight from professionals who work with or around electricity. More than 100,000 electrical professionals were invited to participate in the survey.

ARE YOUR PROSPECTS HOT?

PE pays a visit to the Southampton home of Dimplex UK to learn more about the evolving heating landscape and why now is a great time for electrical professionals to broaden their skillset.

he UK heating market is entering a period of signiﬁcant change. While gas remains the dominant source of domestic heating, the drive towards electriﬁcation is creating a growing role for electrical professionals – and the opportunities extend well beyond simply installing electric heaters. Nick Paul, Head of Product Management at Dimplex, believes the scale of the transition needs to be understood in the context of the UK's existing housing stock. He explains: “Broadly speaking, if we look at the UK market, about 80% of the housing stock is gas centrally heated, about 10% is electrically heated, and then the other 10% is LPG or oil. “The biggest trend that is shaping the UK heating market currently is the talk about heat pumps – both in residential and commercial applications – so we believe this also introduces the need for electrical expertise.”

76 October 2026

However, increased electrification doesn’t necessarily mean that every property will adopt the same solution, with Nick keen to stress that installers will need to understand the characteristics of individual buildings and how different technologies can work together.

“The biggest trend that is shaping the UK heating market currently is the talk about heat pumps...” He says: “There is no one-size-ﬁts-all approach to home heating. While heat pumps can be an effective solution for many properties, some homes may require a combination of heat pump, hot water and electric resistive heating technologies. A good understanding of customer requirements, and the solutions available to them, is therefore essential.”

PROFESSIONAL ELECTRICIAN

This creates an opportunity for electrical contractors to broaden their expertise beyond traditional electrical installation, with technologies such as photovoltaic (PV) generation and battery storage also forming part of the conversation. Time-of-use tarrifs One reason is the anticipated growth of time-of-use electricity tariffs. Indeed, Nick believes the energy market will increasingly move towards tariffs based on half-hourly pricing, potentially changing how consumers use electricity – and how heating systems can be operated. He explains: “We still have Economy 7 tariffs. Thermal storage is perfect for that tariff because it takes six or seven hours of overnight energy and then releases it slowly during the day. “Looking further ahead, we expect more variable tariffs based on time of use, with the products themselves increasingly designed to respond to this changing environment.” This means that electricians will require a much deeper understanding of the wider electrical ecosystem surrounding them, rather than simply installing individual heating products. That philosophy also extends into ventilation and cooling with the Dimplex heating portfolio and Xpelair ventilation and air conditioning range allowing installers to offer a broader, more complete solution to customers. The new-build market is also an important consideration, with Nick pointing to the importance of Part F and the need for compliant ventilation solutions. And, again, while heating and ventilation systems can operate independently, both are important when considering the performance and comfort of a property as a whole. He says: “At Dimplex we're conﬁdent we offer a one-stop shop solution to

076_PE_OCT26_Layout 1 31/08/2026 18:44 Page 77

customers through both the Dimplex and Xpelair brands – providing them with quality products, a toolkit of training, and other supporting resources. “That combined approach can create opportunities to add complementary services, including ventilation and air conditioning, rather than relying on a single category of work.” It’s clear that education will play a central role in making that expansion successful. To help this process, the Dimplex PRO Installer Club has been developed not just around rewards and incentives, but to create a closer relationship with electrical professionals and give them access to training and practical tools.

Nick explains: “Although rewards and incentives are great, the Club is just as much about helping professionals who need access to training or want to improve their understanding of this sector. “Our investment in training will play an increasingly important role in the future. We’ve established a network of training locations, including our recently opened facility in Leeds, with the aim of making practical training more accessible to installers across the country. “We want installers to have the tools to recommend and fit our products daily. We also want those products to be installed correctly, not least because of the fact it can undermine customer confidence and result in costly call-backs.” Get the job right, first time The Dimplex Advanced Heating Calculator is another example of the support that’s in place to ensure professionals are getting the job right, first time. Available exclusively to Dimplex PRO Installer Club Partners, the tool is designed to support professionals with more detailed heating system calculations, helping installers accurately size systems, avoid both over- and under-specification and ensure the end

user can maintain a comfortable indoor temperature year-round. While the publicly available single-room heating calculator on the Dimplex website is designed for individual room projects, this tool supports more detailed whole-home heating system calculations. . So, what would Nick’s advice to those electricians who are still continuing to dip one or two toes into these particular waters, but now want to dive in head first? “Start learning,” he replies. “There are lots of electrical professionals who are currently missing out on the chance to use or expand their skillsets further, simply because they require training that’s specific to this particular sector. “If you really want to maximise the potential for steady, consistent heating and ventilation work, why not have a look at the training options we provide and come along to one of the courses?

hen Awaab’s Law came into force in October 2025, it marked one of the most signiﬁcant shifts in regulation for registered social landlords (RSLs) in over a decade. For the ﬁrst time, landlords are legally bound to strict timeframes for investigating and addressing damp and mould hazards – with further hazard categories being phased in through 2026 and 2027. In the case of RSLs managing large and varied housing portfolios, this has accelerated the need for proactive asset management, robust ventilation strategies, and tamper resistant building components that support healthier homes. While no electrical accessory can deliver compliance on its own, the right infrastructure can make it easier for landlords to maintain safe, well ventilated properties – and respond quickly when issues arise.

78 October 2026

The new regulatory landscape for damp and mould Awaab’s Law requires RSLs to: ● Investigate damp and mould within 10 working days ● Provide written findings within three working days ● Complete repairs within five working days after investigation ● Address emergency hazards within 24 hours This has placed ventilation in the spotlight. Poor airflow is one of the most common contributors to condensation, damp, and mould – and one of the most preventable. RSLs now need installations that maintain continuous ventilation, prevent unauthorised disabling of fans, allow safe isolation for contractors, and support consistent standards across varied stock. This is where Click’s modular approach offers real value.

PROFESSIONAL ELECTRICIAN

In the wake of last year’s introduction of Awaab’s Law, Jake Green, Head of Technical Engagement at Scolmore Group, discusses why the correct ventilation infrastructure is now a critical consideration. A tamper resistant solution for continuous ventilation Click’s Lockable Fan Isolation Plate, built using the GridPro system, provides a simple but effective way to help landlords maintain airﬂow in properties where ventilation is critical. The solution is created by combining: ● Click’s 10 A 3 Pole Fan Isolation Keyswitch Module ● 13 A Fused Connection Lockable Module ● 2 Gang GridPro Frontplate Together, these components create a tamper resistant, clearly labelled, contractor friendly isolation point. The 3 pole isolator allows safe maintenance by isolating line, neutral, and switched line; the lockable fused module prevents tenants from disabling the fan and the durable, antibacterial frontplate features laser etched markings that won’t fade or compromise the antimicrobial and antibacterial properties of the surface. This doesn’t claim to “ensure compliance” – but it supports the operational reality of meeting Awaab’s Law’s expectations around damp and mould prevention. Awaab’s Law makes it clear that landlords must not attribute damp and

PRIZE DRAW

mould to tenant lifestyle. Everyday activities such as cooking, bathing and laundry inevitably generate moisture, and ventilation systems must be designed to manage this consistently. This creates a practical challenge for landlords: fan isolators are intended for maintenance, not for routine user control. When isolators are switched off or fuses removed, airflow drops – and damp and mould can quickly return. Tamper resistant isolation therefore plays an important role in keeping ventilation active and reliable. Why does tamper resistance matter? RSLs frequently report issues where fans are disconnected, fuses are removed, isolators are switched off, or ventilation is bypassed during tenant repairs. These small actions can lead to big problems – including recurring damp, mould regrowth, and repeat call-outs. A lockable isolation plate helps landlords maintain consistent airflow, reduce avoidable repairs, minimise repeat visits, and support healthier indoor environments. The Lockable Fan Isolation Plate benefits from the wider GridPro platform, including: ● 25 year warranty for long term reliability ● Antibacterial & antiviral certification for healthier environments ● Laser-etched markings that won’t fade ● BSI Kitemarked components for independently verified safety ● Modular design that simplifies maintenance and stock management It also complements the existing electrical accessories typically installed within RSL dwellings, supporting consistency across upgrades, planned maintenance and damp and mould improvement programmes. A flexible, future proof option for landlords The product is supplied as a bespoke configuration, giving RSLs the flexibility to specify exactly what they need for each property type. This is particularly valuable as Awaab’s Law expands to cover additional hazards – including excess cold, electrical safety, structural risks, and fire safety – through 2026 and 2027. A modular, adaptable electrical infrastructure helps landlords stay ahead of these changes. Awaab’s Law has reshaped expectations around damp and mould management. While ventilation is only one part of the solution, ensuring fans remain active, safe, and tamper resistant is a practical step Housing Associations can take today. Click Scolmore’s Lockable Fan Isolation Plate offers a simple, robust, and future-proof way to support healthier homes – and to help landlords meet the operational demands of this new regulatory era.

GETTING DOWN TO EARTH

As ageing installations and modern electronic loads place increasing demands on protective devices, understanding and managing earth leakage has never been more important. The experts at Kewtech explain why effective testing is essential.

arth leakage testing has become an increasingly critical part of modern electrical veriﬁcation and maintenance, particularly as installations age and the cumulative effects of leakage currents become more pronounced. With the widespread use of RCDs and RCBOs providing life-saving protection, understanding, identifying, and managing earth leakage is essential to ensure both safety and reliability.

What is earth leakage? Earth leakage refers to the unintended ﬂow of electrical current from a circuit to earth. This can occur due to insulation breakdown, damaged conductors, moisture ingress, or faulty equipment. Even in healthy installations, small amounts of leakage are inevitable due to the design of modern electrical equipment. However, while these currents are typically harmless in isolation, their cumulative effect across multiple circuits can create signiﬁcant issues. FIG 2 Measuring earth leakage current

RCBOs and nuisance tripping RCBOs and RCDs are designed to detect imbalances between live and neutral conductors and disconnect the supply rapidly, often within milliseconds, when leakage exceeds a set threshold, typically 30 mA in domestic settings. This function is crucial in preventing electric shock and reducing the risk of fire. However, these are not selective devices; they respond to total leakage on the circuits they protect. As a result, they can be susceptible to “nuisance tripping” when leakage currents approach their operating threshold without an actual fault being present. An increasing challenge This challenge is becoming more common due to two key factors: ageing circuits and the rise of modern electronic loads. Over time, cable insulation degrades, becoming brittle, cracked, or moisture-affected, all of which create pathways for leakage current. These faults are often hidden within walls or under ﬂoors, making them difficult to detect without proper testing. In parallel, modern installations now include devices such as LED drivers, EV chargers, electric showers, air-conditioning, and switch-mode power supplies, all of which contribute small but continuous leakage currents. Individually, these leakage currents may only amount to a few milliamps, but when combined across several circuits, particularly on split-load consumer units, they can approach or exceed the protective device’s trip threshold. Cumulative leakage from cable capacitance, appliances, and transient events can easily reach 10-18 mA on a 30 mA RCBO or RCD, leaving very little headroom before unwanted tripping occurs. This is especially problematic in older installations where insulation resistance has already declined. The dangers The danger here is two-fold. Firstly, nuisance tripping can lead to inconvenience, loss of power, and potential damage to equipment. More critically, it may mask genuine faults or lead to complacency, where users repeatedly reset protective devices without investigating the underlying issue.

82 October 2026

“Over time, cable insulation degrades, becoming brittle, cracked or moisture-affected, all of which create pathways for current leakage.” Secondly, ageing or inappropriate RCDs and RCBOs may fail to operate correctly under certain conditions, either tripping too easily or, more concerningly, failing to trip when required. The solution This is where effective earth leakage testing becomes invaluable. Using an earth leakage clamp meter, such as the KEWTECH KEW2434 or KEW2433R, allows you to measure leakage currents quickly and non-intrusively. This can be achieved by measuring the leakage on the earthing conductors, or by measuring the unbalanced load on the live and neutral conductors simultaneously. This enables the identiﬁcation of circuits with elevated leakage without the need to disconnect conductors or disrupt the installation. Testing with a clamp meter provides several advantages. It allows for the assessment of total leakage at the origin, followed by the isolation of individual

PROFESSIONAL ELECTRICIAN

circuits to pinpoint contributors. It also helps differentiate between acceptable “background” leakage and abnormal levels indicating faults. This is particularly important in modern installations where some leakage is unavoidable, and the goal is to manage it rather than eliminate it entirely. Furthermore, with the vast array of tripping characteristics and types of RCB/RCBO now recommended for various applications, appropriate selection is critical and ‘nuisance tripping’ can be a factor, which is why proper measurements should be taken prior to selection. The takeaway As electrical systems continue to age and the number of leakage-producing devices increases, proactive earth leakage testing is no longer optional but is essential. RCDs/RCBOs remain a cornerstone of electrical safety, but their effectiveness depends on the condition of the installation and the level of leakage present. By incorporating tools such as an earth leakage clamp meter into routine testing, electricians can identify issues early, reduce nuisance tripping, and ensure that protective devices operate as intended, ultimately safeguarding both property and lives.

PLAYING IT SAFE

orkplace safety is about much more than simply putting on a piece of PPE. Since its foundation in the USA back in 1983, the Ergodyne brand has focused on understanding the challenges professionals face and developing solutions that help them work smarter, safer and better. The story began with Dr Thomas W. Votel and the development of the first industrial back support – an innovation that saw Ergodyne pioneer the ergonomics category. From that first product, the brand has continued to evolve, building a portfolio of safety solutions that are designed to counter the hazards and challenges encountered by workers every day. Today, Ergodyne is part of the Klein Tools family, with its Tenacious Work Gear range built around three core pillars: Protection, Prevention and Elements. The thinking behind this approach is that effective workplace safety shouldn't just react to accidents; instead it should identify risks and help prevent them, while providing workers with the equipment they need to deal with the environment in which they work.

That philosophy has particular relevance to electricians and installers. Working on-site can involve prolonged kneeling, repetitive movements, hand injuries, dropped tools, slips and trips, as well as exposure to heat, cold and changing weather conditions. Indeed, the ﬁgures contained within Ergodyne's own market research demonstrate why these risks shouldn't be taken lightly. In 2022/23, 473,000 workers suffered from work-related musculoskeletal disorders, resulting in 6.6 million working days being lost. The estimated annual cost of workplace injury was £7.7 billion overall.

Safety is a wider concept Ergodyne's answer is to look beyond conventional PPE and consider the wider concept of worker safety. Its three-pillar approach is designed to provide protection, promote prevention and help workers manage the elements, while products are developed with the needs of those actually doing the work in mind. The brand is distributed by Super Rod, a Klein Tools company, and the focus will be on making it available via the electrical wholesale channel. The UK offering isn’t intended to replicate the complete global Ergodyne

With a 40-year history of workplace safety innovation, we discover why Ergodyne is bringing its distinctive approach to protection, prevention and worker wellbeing across the pond through a familiar electrical industry name. catalogue from the outset, but instead will focus on products from the three pillars that are particularly relevant to electrical contractors, installers and the trade in general. These currently include ProFlex gloves and knee protection, Squids tool-tethering solutions, and selected products from the Chill-Its cooling and N-Ferno warming ranges. Innovation remains central to the brand's development, with Ergodyne boasting more than 100 patents and trademarks. Its approach is also rooted in collaboration, with products developed and tested around the experiences and requirements of workers. The Ergodyne approach goes beyond simply ticking the PPE box, instead focusing on understanding workplace risks, preventing injuries wherever possible and developing equipment that meets the practical demands of the job.

FIRE SAFETY STARTS BEFORE THE ALARM Darren Binns, National Sales Manager at Jefferson Tools, looks at why practical equipment choices can help electricians work with greater control around heat, sparks and everyday site risks.

hen fire safety is discussed in the electrical sector, the focus naturally falls on detection, protection and compliance. Smoke alarms, emergency lighting, fire-rated products and evacuation planning all have a critical part to play. Yet, on the ground, fire prevention also begins much earlier – in the way work is prepared, carried out and supported. Daily working environments can be unpredictable for electricians, maintenance teams and contractors. Plant rooms, workshops, commercial refurbishments and domestic installations may involve multiple trades working side-by-side, temporary materials stored nearby, reduced visibility, awkward access and, at times, activities that generate heat, sparks or open flame.

86 October 2026

Fire safety is often thought of in terms of what happens once a risk has been identiﬁed. But there is a very practical preventative layer, too. It comes down to creating a safer work area, using the right protection for the task, and reducing the chance that ordinary site conditions develop into something more serious. Taking a wider view of heat-related risk Electrical contractors may not always see themselves as carrying out "hot works" in the traditional sense, but heat-related tasks are still common across the broader site environment. Soldering, brazing, cutting, grinding and nearby welding activities can all introduce additional risk, particularly where combustible materials, dust, packaging or temporary coverings are present. This is where small, practical measures can make a big difference.

PROFESSIONAL ELECTRICIAN

Jefferson Tools has introduced a fibreglass soldering mat, designed to withstand temperatures of up to 1,200 °C and help prevent burn damage during soldering or brazing. It’s a simple product, but one that supports a more disciplined approach to protecting the surrounding work area. The same principle applies on larger jobs. Welding curtains and framed welding screens can help create a more clearly controlled zone around tasks that produce sparks, spatter and intense light. Jefferson Tools' range includes 6 ft and 8 ft welding curtain systems, manufactured to EN 25980:2014, alongside replacement curtains that can be fitted to standard frames. On busy sites, one of the biggest challenges is that risks don’t always stay neatly within one trade's working area. A spark, a flash of heat or a poorly contained process can affect people and materials beyond the immediate task. Creating separation and protecting the surrounding area is a very sensible habit.

086_PE_OCT26_Layout 1 31/08/2026 19:33 Page 87

Protection should match the task Personal protective equipment is another essential part of the conversation. Fire safety isn’t solely about preventing ignition; it’s also about protecting the people working closest to sources of heat, sparks and sharp materials. For higher-heat applications, Jefferson Tools has TIG welding gauntlets with Kevlar stitching, carrying relevant EN 388 and EN 407 ratings. The wider PPE range also includes cut-resistant gloves and general protective handwear, allowing users to select products suited to the type of risk they’re facing. Visibility is also a safety tool Fire prevention can also be supported by something less obvious: better visibility. Poor lighting in loft spaces, utility rooms, outbuildings, service corridors or early-stage construction areas can make it harder to identify hazards before work begins. Cables, packaging, trailing leads, ﬂammable materials and dust build-up are

all easier to miss in low light. Clearer visibility gives tradespeople a better chance to assess the work area, maintain tidier conditions and respond quickly if something changes. Jefferson Tools' lighting range spans headlamps, inspection lamps, torches, work lights and site lights, reﬂecting the varied conditions electricians face – including a hands-free LED neck light which is useful for close-up work. Stable access supports safer work Access equipment may seem slightly removed from a ﬁre and safety discussion, but it has a clear role to play. Rushed positioning, overreaching or unstable working platforms can all make it harder to

carry out delicate electrical tasks with care. Where heat-generating tools, live environments or confined spaces are involved, a lack of control becomes even more problematic. Jefferson Tools' fibreglass stepladders are designed for environments where there may be a risk of contact with electrical wires or equipment. The range is manufactured and tested to BS EN131:2010+A2:2017 and offers 30,000 V insulation, alongside added stability features. Fire safety starts long before an alarm sounds. It begins with how the work is set up, how well the risks are understood and how consistently people use the right equipment. When those habits are in place, contractors can work with greater control, confidence and care. BROWSE JEFFERSON TOOLS’ RANGE OF TOOLS AND EQUIPMENT BY VISITING: WWW.RDR.LINK/ECC038

Shocking Energy puts L&B in control company win new contracts requiring SIP-accredited engineers, while increasing its capacity to support future growth.

As the renewable energy market continues to expand, electrical contractors are facing greater pressure to complete installations safely, efficiently and with minimal delays. Greater control over its renewable energy projects has enabled L&B Electrical to enhance customer service while creating a stronger platform for future growth. The NICEIC Approved Contractor, which serves domestic, commercial and industrial customers across Derbyshire and the Midlands, had traditionally relied on Distribution Network Operators (DNOs) to de-energise and re-energise properties before certain installation work could begin. Unwelcome delays While necessary, waiting for DNO attendance could introduce delays and make it more difficult to schedule work around customers. L&B Electrical therefore wanted to increase the independence of its engineers while maintaining the highest standards of safety and compliance. The company partnered with Shocking Energy to achieve Safe Isolation Provider (SIP) Accreditation, enabling its engineers to safely undertake isolations without relying on DNO attendance for every installation.

88 October 2026

Shocking Energy supported L&B Electrical throughout the accreditation process, helping prepare technical and compliance documentation, complete practical assessments and establish the operational processes required to maintain ongoing compliance and best practice. The business also implemented Shocking Energy's Jobway digital job management and compliance platform, integrating SIP requirements into its day-to-day operations. This provided engineers with a consistent and efficient way to manage installations, with compliance built into every stage of the workflow. Rather than treating accreditation as a one-off exercise, the process focused on creating lasting operational improvements, giving L&B Electrical the knowledge, confidence and systems needed to maintain high standards as its renewable energy offering continues to expand. Since achieving SIP Accreditation, L&B Electrical has greater control over its installation programme, allowing the business to schedule projects more flexibly, reduce delays caused by waiting for DNO attendance and provide a faster, smoother service for customers. The accreditation has also helped the

Accredited isolation services L&B Electrical has additionally joined Shocking Energy's Isolator Installer Network, allowing it to provide accredited isolation services for other electrical contractors and renewable installers that do not hold SIP Accreditation. This can help projects proceed without unnecessary delays while ensuring isolation work is carried out safely and in accordance with industry requirements. Tom Carter, Director of L&B Electrical, commented: “As our renewable work continued to grow, we wanted greater control over our installation programme and less reliance on third parties. SIP Accreditation has given us that flexibility. We can now schedule work more efficiently, reduce delays and keep projects moving for our customers. “It has also helped us win new work, as we're now able to offer a level of capability and flexibility that some clients specifically look for. Shocking Energy supported us throughout the entire process, from the accreditation itself to embedding the right procedures into the business.
