Editor’s Viewpoint

A relationship you can count(er) on It would be easy to assume that the rise of online ordering, next-day delivery and price comparison tools would have fundamentally changed how electricians source their materials. In many industries, it already has.

But spend any time talking to UK electricians and a different picture emerges. The wholesaler counter – that familiar early-morning stop or mid-job dash – remains not just relevant, but central to how many professionals operate.

Recent reader survey data from Professional Electrician & Installer’s 2025 Reader Survey underlines that point.

Nearly 60% of electricians are visiting a wholesaler at least once a week, with over 25% showing their face every single day.

For a trade that has seen rapid digital change, that’s not a habit but a choice instead. And it says something important about what electricians value.

On paper, convenience should favour online. A few taps, a quick checkout, and materials often arrive the next day. But electrical work doesn’t always follow a consistent schedule. Jobs change, faults appear, specifications shift. When that happens, waiting isn’t an option.

The wholesaler offers something digital platforms struggle to replicate: immediacy combined with understanding. You can walk in with a problem, not just a product list, and walk out with a solution. That interaction matters more than it might first appear.

Survey responses show that while availability of products is the biggest single factor (33.6%), relationship and loyalty (23.6%) and customer service (18.8%) together outweigh price alone. In fact, price accounts for just 17% of decision-making.

That’s a strong signal. Electricians are choosing reliability, familiarity and trust over simply chasing the cheapest option.

And trust is built face-to-face.

At the counter, conversations are fluid and grounded in experience. You can sense confidence in a recommendation, ask follow-up questions, or explain a job in

a way that doesn’t fit neatly into a search bar. There’s a shared language that comes from being in the trade, not just selling to it.

It’s also one of the last regular touchpoints in the working week where electricians interact with others in the industry. For many, especially sole traders, that brief exchange at the counter can be the only in-person conversation with someone who truly understands the job.

There’s also a practical advantage in how knowledge flows. Nearly 40% of electricians say they find information about new products through wholesaler counter staff. That filtered, experience-based insight sits somewhere between manufacturer claims and real-world application.

And when quality is the top priority for 76% of electricians choosing products, those recommendations carry weight.

The wholesaler also provides accountability in a way that’s harder to achieve online. If something isn’t right, you know where to go. Problems can be resolved quickly, often with a conversation rather than a returns form. That continuity builds confidence over time.

None of this is to dismiss digital tools.

They have their place, and for certain purchases they make perfect sense. But the continued reliance on wholesalers suggests that electricians are making a deliberate trade-off. They’re choosing interaction over isolation and in a working world that is increasingly screen-based.

The electrical trade has always been built on practical knowledge, shared experience and trust between people. The wholesaler trade counter quietly reinforces all three. So while technology will continue to evolve, don’t expect the trade counter to disappear any time soon.

Have a good month and enjoy the issue,

Richard B owler PROFESSIONAL ELECTRICIAN May 2026 5

IET issues plug-in solar product warning to households The Institution of Engineering and Technology (IET) is urging the public to consider the electrical safety of their homes before purchasing and using emerging ‘plug-in’ solar products, as the government moves to make these devices available in UK shops as soon as possible.

While the IET supports the ambition to broaden access to affordable, low-carbon energy, it’s essential that households understand that plug-in solar products aren’t typical appliances.

Unlike a kettle or a phone charger, these devices introduce a new source of electricity directly into a home’s wiring system, which may not have been designed to handle this safely.

Mark Coles, Head of Technical Regulations at the IET, said: “Before anyone buys a plug-in solar kit from a supermarket shelf, they need to be aware of the condition and capability of their home’s wiring.

“Many UK homes have ageing, modified or poorly maintained electrical installations. Introducing a generating source into wiring that hasn’t been checked could expose homeowners to risks that aren’t immediately obvious."

He continued: “Before purchasing or plugging in any off-the-shelf generation product, householders should have their electrical installation checked by a competent electrician. What may be safe in one home may pose a significant risk

in another. Professional verification is the only way to be sure.”

Plug-in solar systems aren’t yet legal to use in the UK, as regulators continue to assess how they can be safely integrated into domestic installations.

Current reviews highlight concerns around how electricity flows through older wiring, how protective devices behave when power flows both ways, and how multiple plug-in units may interact during faults or grid outages.

New guide highlights hidden cable risks Wrexham Mineral Cables (WMC) has published the second instalment in its Insurer Series, broadening the focus beyond fire safety to address non-fire electrical failures that contribute to claims, downtime and long-term risk in commercial buildings.

The new guide, Electrical Faults, Corrosion & Rodent Damage: The Hidden Threat to Circuit Reliability, is aimed at insurers, underwriters and risk consultants. It examines how everyday failure modes can undermine building performance and why cable specification plays a critical role in long-term reliability, not just initial compliance.

Building on Part 1, released in November 2025 and centred on fire resilience, the latest publication explores

less visible risks that are often harder to detect, model and manage.

It highlights how issues such as insulation degradation, mechanical stress, moisture ingress, corrosion and rodent damage can lead to outages, equipment damage and business interruption – frequently without any fire occurring. WMC notes that many of these failures develop gradually and remain hidden until a loss event arises, complicating risk assessment and increasing claims exposure.

The guide outlines key considerations for risk professionals, including why compliance at handover does not guarantee performance over a

building’s lifespan, and how cable construction influences maintenance demands, reinstatement costs and overall risk predictability.

Gareth Edwards, Commercial Manager at Wrexham Mineral Cables, said: “Fire survival is only part of the picture for insurers. This guide focuses on the everyday failure modes that erode reliability over time and demonstrates how informed cable specification can reduce uncertainty and support more predictable underwriting outcomes.”

As with the first publication, WMC positions Mineral Insulated Copper Clad (MICC) cables as a solution for reducing vulnerability at source, supporting long-term circuit integrity and resilience.

COVER STORY

TO INFINITY AND BEYOND Ovia has expanded its domestic lighting product portfolio with the introduction of the Infinity COB LED Strip. We discover more about how this new lighting solution is designed to deliver smooth, dotless illumination across a wide range of applications.

D

eveloped to meet growing demand for discreet architectural lighting, the Infinity COB Strip provides a modern lighting solution for installations where consistent light output and clean visual lines are essential. It’s suitable for use in residential environments such as kitchens and living areas, as well as commercial spaces requiring refined, continuous lighting effects.

Seamless illumination with COB technology COB (Chip on Board) technology integrates LED diodes directly onto a printed circuit board. A phosphor coating is then applied across the LED chips, which acts as a built-in diffuser.

This construction creates continuous, uniform light output without the visible spotting often associated with traditional LED strips.

The result is a seamless illumination effect that delivers a refined finish, particularly in installations where the strip itself may be visible.

Standard and Pro Series options The Infinity range is available in both Standard and Pro Series variations, offering options to suit a wide range of projects and performance requirements.

The Standard range delivers an average light output of 100 lumens per watt and is available in 8 W and 12 W versions, supported by a three-year warranty.

The hub is sold separately.

Single colour, adjustable warm/cool white lighting options and RGB The Infinity COB range is available in five colour temperature options, providing lighting designers and installers with flexibility across different applications:

“To ensure a high-quality finish, Ovia offers a selection of aluminium extrusions designed for use with the COB Strip.” ● 3000K warm white ● 4000K cool white ● CCT adjustable white (2700K to 6500K) ● RGB3K (RGB plus 3000K white) ● RGB4K (RGB plus 4000K white) These options allow installers to create both practical task lighting and dynamic decorative effects within the same lighting system.

Compatible drivers for enhanced power The Infinity COB Strip operates on a 24 V constant voltage platform and is supported by a comprehensive driver range offering outputs from 30 W to 250 W. ● Linear drivers are available in 30 W, 60 W, 90 W, and 250 W options. ● Triac dimmable versions are offered in 75 W and 150 W for installations requiring Triac dimming control. ● Compact drivers are offered in 30 W, 60 W, 90 W, and 120 W formats and are ideal for applications where space is limited ● IP67 rated drivers, available in 100 W, 150 W, and 200 W, are suitable for environments requiring robust ingress protection.

Both linear and compact driver formats give installers the flexibility to choose the most appropriate configuration for each project, ensuring optimal performance and seamless integration.

Extrusion solutions for a professional finish To ensure a high-quality finish, Ovia offers a selection of aluminium extrusions designed specifically for use with the Infinity COB Strip.

Four profile options are available including surface mounted, recessed, corner and plaster-in. Each extrusion is available in black or silver – plaster in profile in silver only – to complement a wide range of interior aesthetics.

To support installation, a range of accessories is also available, including a joining kit for plaster-in profiles to align and secure sections during fitting, and a suspension kit that allows the corner extrusion to be used as a suspended luminaire.

Comprehensive accessory options Installers can select from six connector types designed to simplify installation and enable more complex lighting layouts – starter leads, joining connectors, joiner leads, l-shape connectors, x-shape connectors, and t-shape connectors.

SPECIAL REPORT

THE WORLD’S AT YOUR FEET

W

ith a big summer of football just around the corner, anticipation is already building for the World Cup. For many of in the trade, that means planning jobs around kick-off times, keeping one eye on the score while fitting some sockets, and sweepstakes running on-site.

But while most of us are content with five-a-side after work or a Sunday league run-out, a select few have gone from wiring circuits to performing under the brightest lights in world football.

In keeping with the game’s working class roots, let’s take a look at some of the players who once earned their living in the trades before turning pro – with some who made it all the way to the World Cup itself.

And who knows? With enough graft, a bit of luck, and a decent first touch, you might make the squad yourself one day.

KEITH LASLEY A true servant of Scottish football, Keith Lasley is best known for his long association with Motherwell, where he made over 300 appearances and captained the club during one of its most competitive modern eras.

But before cementing himself in the professional game, Keith trained and worked as an electrician – and notably didn’t completely step away from the trade even during his playing days. Like many in the Scottish leagues, where wages haven’t always matched those south of the border, having a trade behind him provided both stability and a fall-back.

From site to stadium, we profile those sparkies – former and current – who have made it to the footballing big leagues.

CYRILLE REGIS A pioneer of English football and a powerful forward, the late Cyrille Regis also had roots in the trades. Before his breakthrough with West Bromwich Albion, he trained as an electrician while playing non-league football.

Like many young players at the time, he combined work with football, honing his craft in local leagues before being spotted by professional clubs.

Cyrille earned five England caps and was part of the wider squad during the era leading up to the 1982 World Cup, though he didn’t make a finals appearance. Nonetheless, his journey from apprentice electrician to top-flight footballer remains an inspiring one.

IAN WRIGHT

STUART PEARCE Known to fans as “Psycho” for his no-nonsense approach, Stuart Pearce is one of the most famous examples of a tradesman-turnedfootballer. Before his rise to the top of the game with Nottingham Forest and England, Stuart worked as an electrician.

In fact, he famously balanced his electrical work with playing duties well into his early career, only going full-time once his place in the professional game was secured.

Stuart, who currently serves as a Patron for our industry charity, EIC, went on to earn 78 caps for England and represented his country at the 1990 World Cup in Italy, where England reached the semi-finals. We’ll leave that particular story there…

Before he became a household name with Arsenal and England, Ian Wright’s early working life included time spent grafting in manual trades.

While not strictly an electrician, Ian spent time in construction-related jobs and on-site environments before his late entry into professional football.

What makes Ian’s story remarkable is how late it all happened – he didn’t turn professional until his early twenties after being released as a youngster. It’s a reminder that the path isn’t always straightforward.

Ian would achieve scoring feats for the likes of Arsenal and Crystal Palace in his career, and has since become a successful pundit.

He went on to play at the 1998 World Cup for England, proving that even those who start out far from the academy system can make it to the very top.

STEVE BROWN At the other end of the football pyramid, Steve Brown of Chesham United represents the modern-day non-league grafter – the kind of player many in the trade will instantly relate to.

Alongside his footballing commitments, Steve has worked as an electrician, balancing the demands of installations, call-outs, and site work with training sessions and match days.

It’s a juggling act that requires serious discipline – swapping tools for boots and back again, often within the same day.

Non-league football remains full of players like Steve, where the love of the game runs parallel with earning a living in the trades.

Q&A

Pete ‘Monty’ Monfort, Director at Arena Training, discusses the launch of the company’s new York-based AM2 centre, the importance of flexible assessment routes, and how closer industry collaboration is helping to shape the next generation of electricians.

“LET’S TALK YORK!” Arena Training Centre has recently announced the opening of a new AM2 assessment and training facility in York. What prompted the decision to expand with a dedicated AM2 centre in this location?

The York site will offer AM2, AM2S and AM2E assessments.

How important is it to provide a range of assessment options for apprentices and experienced electricians progressing through their qualifications?

Q

Q

Quite simply demand in the region warranted another centre and discussions with NET led to us selecting York.York is also a transport hub that’s easily accessible from the A1, M1 M62 and rail. The centre is a bus ride away from the station with cheap hotel accommodation within walking distance which literally makes it available to apprentices from across the UK. I also grew up in York so it was nice to open a business there.

The AM2 is the end point assessment for the electricians following approved training pathways. The assessments are similar and this means we can cater for students following a range of different pathways. We might also see the centre being used to deliver training as well, as we have space to offer EV, Regs and inspection and testing courses.

Alongside assessments, the centre will offer preparation courses and practice days. How valuable is this kind of support for candidates preparing for the AM2, and what can trainees expect from the training environment in York?

Q

In terms of preparation for AM2 the official line is that candidates who have followed an official training pathway should have gained the relevant experience in the classroom and on the job to prepare them for the AM2 assessment.

However, we’re increasingly finding that candidates are missing experience in vital areas including inspection and testing, fault finding and some aspects of installation.

We offer training to address shortfalls in skills/learning rather than ‘teaching to the test’. We encourage candidates to realise the AM2 is an assessment of

26 May 2026

026_PE_MAY26_Layout 1 08/04/2026 11:46 Page 27

employers have seen the value that our relatively small but regionally-focused offering is providing, with our progress rates second to none.

Alongside us will be Thomas Flewitt, creator of TradesBoard, a website/App designed to help learners find employment and work experience.

For electricians and apprentices visiting the show, what can they expect to see or learn from Arena Training Centre on your stand?

Q occupational competence. If candidates address understanding and skills issues, they will be fit to work in any scenario, including the AM2 assessment centre.

Arena already operates its main training centre in Sheffield. How does the new York facility complement the existing provision, and what does it mean for electricians and apprentices in the wider Yorkshire region?

Q

The new centre adds capacity for us to offer AM2 assessments at short notice and it means we are well placed to support training providers across the UK that work regularly with us. It may also mean that we can offer some electrotechnical training to professionals in York too.

Arena Training Centre will be exhibiting for the first time at the upcoming ELEX Show in Harrogate later this month (14th & 15th May). What motivated you to take part in the show this year?

Q

We recently developed a working partnership with The Sheffield College who are now offering electrical apprenticeships in partnership with us.

The decision to exhibit came out of discussions with Sheffield College as a way to let electrical contractors in our region meet with our team and see if our partnership can work for them.

With two cohorts already in training and a third starting shortly it is clear that

Visitors will find out about our amazing team that are focused on quality and standards. With many of our tutors and assessors balancing being on the tools with working at Arena, we have a team that are in tune with the industry and challenges facing electricians.

Visitors will also find a myriad of opportunities they can tap in to in order to recruit high quality learners/apprentices with a focus on cost-effectiveness.

Delegates can talk to us about our accelerated apprenticeships and understand how a learner with prior experience and learning means the cost of taking on an apprentice becomes workable, even for small employers. We will also have some great giveaways too.

COMMENT

“SOME OF US ARE WIRED DIFFERENTLY ” Andy Wallis, Director at Redwood Electrical Services, discusses a few of the challenges of navigating daily life in the electrical trade when dealing with neurodiversity.

I

started out like many in the industry – straight from school and into an apprenticeship. I was 17 when I joined Buchanan & Curwen in Leatherhead, combined with a day release at Carshalton College. I got through my qualifications with decent grades, but when my apprenticeship ended on my 21st birthday I was let go.

From there, I moved around. My path led me to seven years with BT Openreach as a cable jointer, then into security systems, environmental monitoring, and eventually sales. It wasn’t a straight line, but I kept moving.

Then my wife lined up a subcontracting opportunity for me with an electrical firm. I got my 17th Edition and went back on the tools. Four years later, in 2014, I started Redwood Electrical Services. A year after that I gained my NICEIC Domestic Installer, along with ECA accreditation and an ECS Gold card – everything needed to run properly as a spark.

Daily struggles I’ve had Tourette’s since I was a teenager – mainly motor tics. It’s something I’ve always lived with. My eldest son has it too, and my youngest has dyspraxia and ADD. In our house, that was just normal life.

One thing I’ve always struggled with is procrastination. Whether it was jobs, paperwork, or studying – I’d leave things until the last minute, even when I knew better. I just thought that was me.

Then my eldest son started having problems with things like concentration,

“I don’t see neurodiversity as just a negative. It can be a strength – problem-solving, thinking differently, even hyper-focus.”

exams, and staying organised. He got through university with a degree in banking, finance and economics, but struggled to hold down a job. A friend suggested ADHD testing.

Once he was diagnosed and started medication, the change was unbelievable. He was focused and disciplined, getting things done as a result. Watching that made me stop and think, because a lot of what he’d been doing, I recognised in myself.

Trying to get assessed So I went to my GP to get the ball rolling on an ADHD assessment. That’s when I realised how difficult the system can be.

There’s a pathway called “Right to Choose”, but the criteria are strict. You have to tick very specific boxes – things like safeguarding involvement, legal services, or being at risk of losing employment with formal evidence.

But as electricians, especially if you’re

028_PE_MAY26_Layout 1 08/04/2026 12:18 Page 29

self-employed, what does “proof of repeated loss of employment” even mean? We go from job-to-job, on a daily/weekly basis.

In the end, after no assessment and little progress, I went down the private route. I won’t sugar-coat it – it’s expensive. But I felt like I had no choice. If there’s something going on, I need to understand it and get it under control.

This isn’t just about feeling distracted.

It has real knock-on effects. Running a company, managing jobs, keeping on top of qualifications – it all requires focus.

And that’s where it starts to overlap with what’s happening in the industry right now.

Qualifications and pressure There are proposed changes in the offing meaning that if you’re acting as a QS and carrying out EICRs, you’ll need the 2391-52 inspection and testing qualification. At the moment, I don’t have it and will have to undertake training and examinations to acquire it.

Which means, when that becomes mandatory, I can’t sign work off – and the business doesn’t run. That’s three people out of work. And I know I’m not the only one in that position.

A lot of experienced sparks I’ve spoken to are saying they’ll opt back to maintenance work rather than go through the process. At a time when we’re already short on skilled trades, that feels like a backwards step.

Here’s where ADHD and the trade

really intersect. If you’ve got ADHD traits – diagnosed or not – studying, revising and exams aren’t always straightforward. Without support, it can feel near impossible.

So bringing in tighter qualification requirements without considering how people learn risks pushing experienced electricians out of the industry. Fewer people carrying out the work means higher prices, longer wait times, and more pressure across the board.

From what I can see, this side of things hasn’t really been considered.

Strengths and weaknesses I don’t see neurodivergence as just a negative. It can be a strength – problem-solving, thinking differently, even hyper-focus. But when you’ve got multiple things going on – Tourette’s, ADHD traits, etc. – it can be exhausting. You’re not just doing the job, you’re managing yourself at the same time.

We’re good at cracking on and getting the

“If you’ve got ADHD traits – diagnosed or not – studying, revising and exams aren’t always straightforward.

Without support it can feel near impossible.” job done. But sometimes it’s worth saying this bit’s tough – whether it’s navigating the healthcare system, keeping up with qualifications, or staying on top of everything day-to-day.

A bit more understanding from those that lead the decision-making process in our industry would go a long way.

Because behind every business and every van on the road, there’s a person trying to make it work – and not all of us are wired the same way.

CODEBREAKERS THOMAS HILL: WE HAD A PROBLEM WITH SOME SOCKETS NOT WORKING ON A RECENT JOB. I REMOVED THE BOARD COVER AND FOUND THIS… Fault finding is often the result of a lack of regular inspection and testing of an electrical installation, or, as in this case, additional external influences affecting the integrity of the installation.

It is evident that there has been intrusion by mice, where they have been chewing on the single insulated conductors as they enter the RCBOs, which has resulted in contact between the live conductors, leading to the demise of the creature and the operation of the RCBO. Although the RCBO of the socket-outlet circuit has alerted the owner that there is a fault, you can see there is further damage to other circuit conductors, which remain energised. The consumer unit also appears to have suffered some distortion, either as a result of the short-circuit or from poor original installation.

Remedial work may involve re-terminating the conductors or might even lead to a partial or full rewire, or at the very least a further investigation for vermin damage to the cables installed within the installation.

While not strictly an electrical issue, the property owner would need to tackle the vermin infestation prior to the remedial works being carried out or the same outcome would likely occur again.

Therefore, the appropriate classification code would be a C2, Potentially dangerous, urgent remedial action required due to the damage to the circuit conductors and further damage within the cabling of the installation.

ANDRIY BURLAKA: INTERESTING USE OF THE EARTH ON THIS ONE!

When undertaking periodic inspection and testing, part of the procedure involves carrying out sample inspections of accessories.

In this case, the sample revealed a failure in the understanding of correct conductor selection.

A circuit protective conductor (cpc) shall only be used for the purpose of earthing. It must not be used for other purposes and must never be oversleeved or re-identified as a live conductor.

In this situation the bare cpc of a pvc/pvc cable has been utilised as a switch wire, which introduces further issues. The cable is then provided with only basic insulation, rather than the insulated and sheathed protection provided by the red and black conductors.

This appears to be the result of non-compliant work, where either two way switching has been

introduced or an additional switch wire was required, instead of installing new cabling. The absence of a cpc at the metallic light switch and other metallic lighting points introduces a potential risk of electric shock in the event of a fault.

Therefore, the appropriate classification code would be a C2, Potentially dangerous, urgent remedial action required due to potential damage to the conductors and the lack of cpc for the lighting circuit accessories.

IMPEDANCE AND ITS IMPACT ON VOLTAGE DROP IN CABLES This article from the experts at NICEIC examines impedance, and more specifically, considers its impact on voltage-drop in cables when supplying electrical loads having a poor power factor. This will be demonstrated with a practical example. It is worth noting that such considerations are rarely required in a domestic dwelling where most cable sizes are typically less than 16 mm2. It may be useful to refer to Appendix 4 of BS 7671 when working through the examples given in this article.

Impedance v Resistance Resistance is a property that opposes the flow of current. In a direct current (DC) circuit under steady-state conditions, resistance is the only opposition to current flow.

However, when considering an alternating current (AC) in a circuit, it should be remembered that other factors such as the effects of inductance and capacitance must also be considered.

The influence of inductance and/or capacitance on a circuit is dependent on the supply frequency. The term ‘reactance’ is used to describe these effects, which can be either inductive or capacitive.

Key terms: Resistance, Reactance, and Impedance Further consideration of the terms resistance, reactance and impedance include:

impose changes in current or voltage.

Reactance exists wherever there are magnetic (inductive) or electrostatic (capacitive) fields, in which its value depends on both the inductance/capacitance elements, and the frequency of the supply.

If a circuit containing only reactance was connected to an AC supply, the effect of the rate of change of supply voltage would cause the circuit current to either lag or lead the voltage by 90o depending on whether the element is inductive or capacitive respectively. ● Impedance (Z): measured in ohms (Ω) is the total opposition to current flow in an AC circuit containing both resistance and reactance. This can be determined using the equation: Z = √R2 +X 2

● Resistance (R): measured in ohms (Ω) is an inherent property of all conductors. When alternating current passes through a resistance, it causes a voltage-drop that is in-phase with the current. ● Reactance (X): measured in ohms (Ω) is the opposition on circuit elements, such as in capacitors and inductors, to

“When alternating current passes through a resistance, it causes a voltage-drop that is in-phase with the current.”

Fig 1. Impedance triangle showing relationship between circuit components and power factor

Impedance is present in most circuits supplied from an AC source. As such, the current flowing through an impedance will be out of phase with the supply voltage by an angle between 0o and 90o.

The power factor of the circuit can be determined using the trigonometry ratio: cosϕ = R Z The relationship between these three terms is shown in the impedance triangle of (Fig 1).

In order to establish the design current (Ib) for a specific circuit, the impedance must be determined. The design current can be found using: Ib= Uo Z

Distribution and circuit cables In cable analysis, each line conductor of the distribution or circuit cable can be modelled as having a series resistance R and an inductive reactance XL, as shown in the single-line diagram of (Fig 2).

tabulated (mV/A/m)z values should be used (see Equation 1).

Fig 2. Line diagram showing the component parts of a cable

Capacitive reactance XC is generally a concern for parallel conductors operating at high voltage and over longer distances, such as transmission cables.

Such effects are negligible for distribution and circuit cables and are therefore not shown in Fig 2.

Where circuit cable conductors exceed 16 mm², which is common in distribution circuits used in industrial or commercial type installations, the tables for current-carrying capacity and voltage-drop in Appendix 4 of BS 7671 give separate values of voltage drop per ampere per metre (mV/A/m) for r, x and z.

The intention of BS 7671 in providing individual values of r, x and z in these tables is to allow for an accurate assessment of voltage-drop to accommodate loads having a large inductive element, for example induction motors or capacitive elements, such as those providing noise filtering within electronic equipment. Generally, most connected loads will be inductive in nature.

Appendix 4 of BS 7671 recognises, in paragraph 6, that where there is power factor in a circuit, the use of the tabulated values of mv/A/m may lead to a calculated value of voltage drop which is higher than the actual value. Where the power factor of the load is not known, the

“When carrying out circuit design, using the load power factor will provide a more accurate value...”

However, if the load power factor is known, then using the tabulated (mV/A/m)r and (mV/A/m)x values will provide a more accurate assessment of voltage-drop (see Equation 2). See also (paragraph 6) of Appendix 4 of BS 7671.

When carrying out circuit design, using the load power factor will provide a more accurate value and will in most cases result in a smaller conductor size.

Example Consider a 100 kVA three-phase induction motor having a design current (Ib) of 144 A with a power factor of 0.75 lagging and cable route length of 120 m.

From Table 4H4A a 70 mm2 aluminium cable has been selected and from Table 4H4B column 4, the mV/A/m values are: r = 0.90, x = 0.14 and z = 0.92. Assuming no other factors apply, determine the volt-drop in the supply cable.

100 ×103 The design current (Ib) = = 144 A √ 3×400 (i) If the power factor was not known, equation 1 would be used: voltage drop= 0.92 x 144 x 120 = 16 V 1000 (ii) If the power factor is known, equation 2 would be used (see Example 2).

Table 4Ab in Appendix 4, recommends that the maximum voltage drop from the origin of the installation to the point of utilisation should not exceed 5 % of the nominal supply voltage1 this equates to 20 V (5% of 400 V).

“Capacitive reactance Xc is generally a concern for parallel conductors operating at high voltage over longer distances, such as transmission cables.”

If, for illustration purposes, 5 V of this permitted 20 V allowance is assumed to have been dropped upstream in the distribution cable, then using equation 1 (z value), the calculated voltage drop for the final circuit is 16 V, giving: 5 + 16 = 21 V (exceeds the 20 V limit) This would indicate that the chosen conductor is undersized and that a larger conductor CSA is required to achieve conformance.

However, using equation 2 (r and x values with known power factor) gives 13.3 V for the final circuit, resulting in a voltage drop of: 5 + 13.3 = 18.3 V Using equation 2 demonstrates that the final circuit would conform without unnecessarily upsizing the conductor CSA when the load power factor is known.

Summary This article has used a practical example to help examine the impact of impedance on voltage-drop in circuit cables, particularly when supplying electrical loads with poor power factor.

For large industrial type installations, using the known power factor in voltage-drop calculations often yields a more accurate result, allowing the selection of a smaller CSA of conductor size while optimising cable design and reducing installation costs.

STAYING

P

roving dead effectively and safely is vital when it comes to safe isolation and reducing the number of electricity-related injuries within the workplace.

However, there are other hazards to factor in – like potential injuries caused by coming into contact with unexpectedly live metal parts.

Safe isolation process There has been significant activity from both electrical industry bodies and electrical test equipment suppliers, driving awareness around the subject of safe isolation. The process states that the relevant breaker or switch has to be identified, locked off correctly, tagged and the circuit verified dead before proceeding.

For an effective safe isolation process it is key to ensure the correct equipment is available. Voltage Indicators (VI) must comply with legal safety standards, namely BS EN61243-3 and BS EN61010-1.

Products such as Martindale’s VI13800 voltage indicator have been specifically designed to meet the standards.

Also important is ensuring that the Lock out, tag out (LOTO) items available cover all potential isolation requirements.

Generally, this would consist of a selection of MCB lock off devices, lock out tags, warning labels, padlock/s with a

unique key/s, and a hasp if more than one person is working on a system.

When the correct equipment is available and the electrical circuit is locked off, the basic proving dead process involves an initial prove, testing the VI against a proving unit to make sure it is working correctly.

The next step is voltage test. The proved VI is used to check for dangerous voltage levels on the circuit to be worked on, whether single- or three-phase.

Steve Dunning, Managing Director of Martindale Electric, explains the hidden electrical dangers that can occur when they are not checked as part of the standard safe isolation process.

Finally, prove the VI against the proving unit again before starting to work on the circuit. This ensures the VI is functioning and working correctly to make sure that no damage has occurred, or fault has appeared, on your equipment.

It is always recommended to use a dedicated proving unit matched to the VI to fully test that all LEDs on all ranges are working. A proving unit is safer than the mains and provides a live source wherever you are working.

Additional hazards Despite the rigorous process of safe isolation, other types of electrical hazards can still be present when working on electrical systems.

One such issue is injuries caused to engineers, contractors, electricians, and others by encountering unexpectedly live metal parts including metal casings on equipment or appliances, pipework, plumbing, and other types of metalwork which should be earthed. This invisible danger can be present in any workplace situation ranging from simple domestic wiring through to commercial and industrial installations.

There are many types of faults which can cause live metalwork, including: incorrect or hazardous wiring, trapped cables, and Protective Earth Neutral (PEN) faults.

Widely discussed in the industry, the PEN fault is where a break or "open circuit" occurs in a PEN conductor which serves as both the neutral and protective earth. PEN conductors are generally present outside of an installation and are separated into a neutral and protective earth at the consumers supply connection, the split providing a safe local separate earth.

The combined PEN conductor’s primary role is a return path for normal load current while also serving as the protective path for fault currents, ensuring that exposed conductive parts remain at or near-earth potential.

A broken or faulty PEN conductor can cause dangerous voltages to appear on metalwork, creating an electric shock risk, fire risk, and/or equipment damage. PEN faults in electrical supply systems can cause safety issues regarding electrical vehicle chargepoints; to combat this modern EV chargers should incorporate PEN fault protection.

Further safety checks – touch voltage Touch voltage is the electrical potential difference between exposed metalwork and the earth due to a fault condition.

The standard safe isolation process does not check for potentially live metalwork, so performing a touch test is an essential addition.

There are a number of tools available which are used for performing this test, primarily non-contact and single-pole contact indicators. Unlike a compliant safe isolation voltage indicator both require batteries and should always be fully checked for functionality prior to use.

Non-contact voltage detectors should always be used with caution as they can often be sensitive to other signals such as static electricity. Care should also be taken regarding the voltage threshold of the indication to ensure that unsafe voltages can actually be detected. It’s also not possible to prove they are working correctly with a standard proving unit.

Single pole contact indicators are a more reliable solution and can be incorporated into touch test safety procedures to help identify potential issues. For example, the Martindale VT7 is a single-pole contact voltage indicator which detects AC voltages of 50-600 V. This type of tester should always incorporate a self-test function and preferably be IP rated for indoor and outdoor use.

Diverted current fault A diverted current fault occurs when electrical current flows away from its intended path due to damaged insulation, earth or neutral failure and other types of faults. This can create an abnormal current flow causing overheating, equipment damage, and potential electric shocks from unexpectedly live metalwork. While this fault is present the circuit may appear to be working correctly.

Diverted current can be identified by checking for current flow, where appropriate, using a suitable clamp meter such as the Martindale CM79.

Measuring the earthing conductor while the circuit is supplying load can help identify diverted current. Low level leakage currents would be considered normal, but readings of several amps indicate a potential fault condition, possibly an open circuit PEN conductor.

Safety first Safe isolation is neither complex nor costly but is vital for compliance with the Electricity at Work Regulations and for preventing harm. Locking off devices, using compliant voltage indicators, and proving dead with proving units are central to the process.

Being aware of the risks associated with live metalwork is also key and, before working on any installation, precautions should be taken to identify hazardous touch voltages on exposed or extraneous metal parts.

By embedding these procedures, workplaces can significantly reduce the risk of electrical accidents. Safety must always remain the priority, and the correct safe isolation procedure provides the foundation for protecting both people and infrastructure.

There’s a wealth of online support materials to help generate safe electrical working procedures. The Martindale ALIVE campaign is a simplified and easy way to remember the process and assist with safe isolation implementation, while the “STOP. No Check. No Contact” covers the hazards associated with live metalwork.

THE CPD ZONE

REPORTING FROM THE FIELD Jonathan Swain, Technical Writer at NAPIT, discusses the oftenoverlooked skill of completing an Electrical Installation Condition Report (EICR) accurately and professionally.

T

he completion of an EICR can be daunting. Few of us chose this career for our love of paperwork.

This article focuses on the actual completion of the report, see Fig 1.

While less glamorous than other aspects of the inspection process, accurate and consistent documentation is equally important.

The report tells the story of the installation, and the clearer the story is, the better understood, and safer the installation will be throughout its service life.

Along the way, we’ll share tips and feedback from NAPIT members and field officers to highlight the difference a NAPIT-certified inspector can make, and address some of the common mistakes.

When completing an EICR form, Section A records client and installation details and Section B states the reason for the report. These are generally straightforward, but should be completed carefully to ensure accuracy – especially Section B, as it provides context for the decisions recorded later.

Since these first sections are usually simple, we’ll move on to a part that is often overlooked.

If no records are available, sampling could be inappropriate, there’s nothing to compare to, and 100% inspection and test may be required, with no limitations.

Ironically “100% of the installation” is one of the most common statements that we see recorded in Section D, often followed by “None” under limitations, see Fig 3. While not impossible, this is highly unlikely (and risky). From both a moral and financial liability perspective, this section is critical.

NAPIT Technical Tip: Any agreed limitation must be discussed and agreed with the client or person

Section C Section C informs and justifies the extent and agreed limitations of the inspection, as displayed in Fig 2.

For example, if an installation has been added to, it’s important to carry out sufficient inspection and testing for both the original and newer parts to obtain an accurate report.

ordering the work in advance. A site survey provides the perfect opportunity for this discussion, with limitations clearly stated in the quotation.

Why limitations matter Periodic inspection and testing presents a unique challenge: the inspector is assessing an installation they did not install and can only work with the information available.

There will always be limitations when inspecting a completed installation in a finished building already in use. Failing to record these limitations accurately can result in an incomplete picture and increase risk of unassessed hazards.

Section D Section D acts as a contract (see Section G declaration), clearly defining the scope of the report and what was inspected and tested. Unexpected issues or operational limitations can be also noted here, allowing all parties to decide if further action is needed.

Accurate documentation is essential because future inspections may rely on your stated scope.

NAPIT Technical Tip: Clear sampling and agreed limitations help inspectors stay focused on-site.

If issues arise, you can adjust the sample rate and invoice separately for the additional work.

Incorrectly claiming that 100% of the installation was inspected and tested with no limitations could lead to a flawed condition report.

NAPIT Technical Tip: The idea that “If it complied when installed, it can’t be dangerous now” is false.

The Inspection must be based on the current edition of BS 7671, including

46 May 2026 PROFESSIONAL ELECTRICIAN

amendments or corrigendums.

Non-compliances do not necessarily mean danger, but it can.

Section E Too often, Section E is filled with a simple ‘satisfactory’ or ‘unsatisfactory’, which is redundant, as the inspector declares this in the overall assessment line directly below.

Instead, think of Section E as your opportunity to summarise the condition of the installation in plain language, see Fig 4. This gives the client a clear overview without the heavy technical detail found elsewhere.

Ask yourself: ‘If I were explaining this in conversation, what would I say?’

Section F The purpose of periodic inspection and testing is to identify defects and non-compliances that could present a risk to people, livestock and property.

This must be done often enough to ensure unreported danger is minimised or (ideally) non-existent. At periodic inspection this recommendation is the inspector’s responsibility and should be recorded and justified in Section F, an example of this is shown in Fig 5.

While generic intervals (e.g. 5 years for commercial, 10 years for domestic) are widely used, each installation must be individually assessed.

The reason for producing the report (Section B) may also be important here as there may be statutory requirements to be considered, for example private and social housing sector legislation.

There may also be requirements from other interested parties such as insurers and licensing authorities that will inform the recommendation.

Use your professional judgment, based on the condition found and the utilisation of the installation, to recommend an appropriate interval. Part 3 of the NAPIT Codebreakers publication, particularly table 3.5 (see Fig 6), provides a risk-based approach with three interval options depending on the levels of control and maintenance.

The key question is: how long are you comfortable leaving it, and why?

Section K Sections G, H and I are straightforward so we will now move on to the final section of the form, Section K. Section K is where you document any observations coded on the schedule of inspections or schedule of test results, see Fig 7.

Each observation should be clearly described, with its location specified so future inspectors or contractors can easily identify it.

NAPIT Technical Tip: Testing faults can also be listed here, the wording at the top of Section K includes schedule of test results. Just refer to that.

Whilst we will not be considering coding specifically in this article, when coding, the inspector must make a valid and justifiable assessment of risk using their own knowledge and experience alongside current industry guidance.

It can be useful to qualify the decision

minor works certificate) 2) Underlying design flaws remain unreported and unaddressed 3) Repairs may not be contractually agreed, risking non-payment 4) A conflict of interest may arise if the inspector is also paid for remedial action whilst carrying out the inspection 5) It distracts from the inspection itself In short: the correct process is to issue an “Unsatisfactory” report, then provide certificates for any agreed remedial work.

Where necessary, an Installation Safety Record Summary or Landlords Electrical Installation Safety Record can also be completed to clearly demonstrate that all necessary action has been taken.

NAPIT Technical Tip: A known fault should not be coded “Further Investigation” (FI), it is already known.

Fault-finding may form part of the remedial process, but the report should reflect the observed danger and be suitably coded.

(see the completed example), particularly where an observation is not clear cut and requires some explanation as to why a code has been selected.

NAPIT Technical Tip: The report is not a quote. Observations like ‘needs new fuseboard’ are inappropriate.

The inspector’s role is to find the issue,

not design or carry out the solution.

Avoid silent repairs Some contractors are asked to fix issues on the spot to produce a “Satisfactory” report. This is problematic because: 1) Any ‘work’ must be properly certificated (electrical installation or

Raising standards The so-called “EICR race to the bottom” is driven by cost-cutting agents, unscrupulous contractors and landlords treating the process as a box-ticking exercise.

An EICR is a safety-critical document that demands experience, knowledge and sound judgement, and the ability to record scope and findings with accuracy.

Hopefully, these insights help you produce reports that not only comply with requirements, but also reflect the professionalism and expertise expected of a NAPIT-certified inspector.

THE

RULE

John Hayhurst, Electrical Tutor at City Skills SCC, takes a closer look at the ‘20% rule’, its purpose, application and common misinterpretations.

M

ost electricians are confident they understand the 20% rule.

It is familiar, widely taught, and routinely applied when assessing earth fault loop impedance. For many, its use has become almost automatic when reviewing measured R1 + R2 values or comparing results with the tabulated Zs values in the On-Site Guide. But what if that assumption is wrong?

If the allowance is being applied incorrectly, cables may be oversized unnecessarily, costs increased, and circuit design constrained without a good technical reason. Understanding what this so-called “rule of thumb” is actually for could change the way your circuits are designed and assessed.

What is the 20% allowance actually for?

The 20% factor is often described as a correction for increased conductor temperature during an earth fault.

While conductor resistance does vary with temperature, faults cleared by overcurrent protective devices often occur too quickly for significant heating to take place during the fault itself.

The allowance is better understood as a margin for uncertainty, accounting for factors such as:

● Variations in ambient and operating temperature ● Contact resistance variability ● Workmanship ● Ageing and deterioration ● Changes in bonding and fault paths over time It represents the difference between values measured under controlled test conditions and the impedance that may exist under less favourable, real-world conditions throughout the service life of an installation.

Crucially, these uncertainties arise not from the test method itself, but from how installations behave and change once they are in service.

Zs, R1 + R2, and where the allowance really applies The On-Site Guide implies that the 20% allowance is applied to Zs because Zs represents the complete earth fault loop and determines disconnection performance. While Zs is indeed the parameter assessed for compliance, the technical basis for the allowance lies primarily within the installation wiring.

The factors the allowance is intended to address – temperature variation, contact resistance, ageing, and workmanship – affect the circuit conductors represented by R1 + R2, not

the external supply. The allowance arises because of the parts of the system that are subject to deterioration and variability over time.

Why Ze is excluded Although Ze can change over time due to variations in the supply network and external earth paths, this variability is not what the 20% allowance is intended to address. Changes in Ze are just as likely to improve as they are to worsen, as network impedance is influenced by upgrades, alterations, loading conditions, and environmental factors such as weather.

By contrast, the resistance of installation conductors represented by R1 + R2 can generally only increase over time. For this reason, Ze is treated as a measured condition at the time of verification, while the allowance is directed at uncertainty within the installation wiring.

This misunderstanding is reinforced not only by how the allowance is described in the On-Site Guide, but also by how the calculation is written and interpreted.

A common calculation error: the order of operations A further problem arises not only from where the 20% allowance is applied, but how it is applied mathematically.

PROFESSIONAL ELECTRICIAN May 2026 49

049_PE_MAY26_Layout 1 08/04/2026 19:30 Page 50

THE CPD ZONE

The earth fault loop impedance is sometimes calculated using an expression written as: Zs = Ze + (R1 + R2) × 1.2 Written this way, the calculation is ambiguous. Some calculators process calculations strictly from left to right, while others apply standard order-of-operations rules (BODMAS/BIDMAS). As a result, the same values can produce different answers, depending on the calculator or software used.

If the multiplication is applied to the sum of Ze + R1 + R2, the result does not reflect the intent of the 20% allowance and introduces an error. To eliminate this problem, the calculation must be written unambiguously as:

Measured R1 + R2 values and the limits of testing Continuity testing is carried out with conductors at or near ambient temperature, using low test currents and generally with the installation unloaded.

Under these conditions, R1 + R2 testing confirms that the circuit protective conductor is present, continuous, and reasonably sound at the time of testing.

What it does not do is replicate fault conditions in service. While conductor temperature will certainly increase during a fault, the degree of increase depends on the nature of the fault, the protective device, the installation method, and the fault location.

For this reason, R1 + R2 values should be recorded exactly as measured. They should not be artificially increased by applying a 20% factor.

Zs = Ze + ((R1 + R2) × 1.2) The brackets make it clear that the 20% allowance applies to the R1 + R2 value and not to the sum of these ohmic values.

This highlights that misunderstanding the allowance is not only a conceptual issue, but also a practical one rooted in poor notation and calculation practice.

PROFESSIONAL ELECTRICIAN

Where the allowance is relevant The 20% allowance is relevant when considering Zs as a whole, because Zs represents the complete earth fault loop under fault conditions and includes all conductive paths that may influence fault current return in practice.

This does not imply that protective

bonding conductors are intended to act as circuit protective conductors as, under normal circumstances, fault current returns via the CPC associated with the circuit. However, in real installations, parallel or incidental earth paths can exist through bonded extraneous-conductive-parts, structural metalwork, or interconnected services.

Although these paths are not relied upon by design, their presence – and their variability over time – can influence the effective earth fault loop impedance.

When it is reasonable not to apply the 20% allowance There are circumstances where applying the 20% allowance adds little or no technical value because the conditions it is intended to address are unlikely to arise. The allowance exists to account for uncertainty over time, but where the earth fault path is simple, stable, and predictable, measured values can be a reliable representation of in-service conditions. In such cases, applying a blanket margin risks substituting arithmetic for judgment.

It is therefore reasonable not to apply the allowance where installation characteristics indicate that deterioration,

049_PE_MAY26_Layout 1 08/04/2026 19:30 Page 51

resistance or degradation over time due to minimal vibration, thermal cycling, and mechanical disturbance.

Finally, where a circuit is protected by an RCD, and Zs is not the parameter determining disconnection time, applying an allowance to Zs provides no meaningful improvement in safety assessment. Provided RCD performance is verified, reasonable variations in loop impedance do not affect disconnection.

In all of these cases, the common factor is predictability. Where the earth fault path is simple, stable, and unlikely to change, reliance on measured values without applying the 20% allowance can be technically defensible, provided the decision is informed, justified, and appropriately recorded.

alteration, or variability in the fault path is unlikely to develop to a degree that would affect disconnection performance. This does not remove the need for compliance; instead it recognises that conservatism must be proportionate to risk.

A common example is a dedicated radial circuit supplying a single fixed item of equipment, such as a water heater, pump, or packaged plant. These circuits typically have few terminations, no intermediate accessories, stable load characteristics, and a low likelihood of future alteration. Where measured Zs values are comfortably within limits, the fault path is predictable and unlikely to deteriorate significantly.

Similarly, circuits forming part of a recent installation may justify reliance on measured values alone. Where terminations have been made to manufacturer torque requirements, inspection confirms good workmanship, and there has been no opportunity for ageing or disturbance, the factors the allowance addresses have not yet developed.

Circuits installed in controlled, low-stress environments – such as plant rooms or service risers – are also less likely to experience increasing contact

The role of professional judgement The 20% allowance is not mandatory arithmetic. It is an engineering margin intended to support professional judgement, not replace it. Used appropriately, it strengthens conservative assessment under worst-case assumptions. Used indiscriminately, it risks becoming a procedural shortcut that either conceals genuine issues or introduces unnecessary correction where none is warranted.

Competent assessment requires understanding why the allowance exists, where it should be applied, and when it may reasonably be set aside.

The 20% allowance and EICR coding During an Electrical Installation Condition Report (EICR), measured values are assessed against the requirements of BS 7671 to determine whether the installation is safe for continued use. In this context, the 20% allowance is often misunderstood as a trigger for coding, particularly where measured values are close to maximum permitted limits.

It is important to recognise that the 20% allowance is a design and assessment margin, not a defect threshold. A measured value that falls within the recognised allowance, and still meets the required disconnection times, does not in itself represent a departure from the Regulations.

Where measured Zs values comply with the applicable maximum values and there is no evidence of deterioration,

overheating, loose terminations, or poor workmanship, there is no technical basis for assigning a code solely because the result is “within the 20%”.

A C3 (Improvement Recommended) may be appropriate only where professional judgement indicates a reasonable likelihood that future deterioration could lead to non-compliance. This might include situations where measured values are close to the limit and are combined with observable factors such as ageing, mechanical stress, vibration, repeated thermal cycling, or environmental conditions likely to increase resistance over time.

In such cases, the code is justified by the condition and predictability of the installation, not by the numerical result alone. The recommendation reflects prudent risk management rather than an existing safety issue.

Conversely, assigning a C3 solely because a measured value lies within the 20% allowance risks conflating conservative assessment with defect identification. This approach can lead to defensive coding and inconsistent reporting, neither of which improves safety or clarity.

Conclusion The widespread practice of applying the 20% allowance directly to measured R1 + R2 values reflects a misunderstanding of its purpose. The allowance exists to address uncertainty in real installations when assessing Zs, not to correct individual resistance measurements.

Circuit length alone does not determine whether the allowance should be applied. Predictability, variability, and the likelihood of change over time are the governing considerations.

Understanding these distinctions leads to more meaningful interpretation of test data, better use of professional judgement, and more reliable long-term fault protection.

Working on your own? Need some technical advice? Don’t know where to turn? Ask Megger. What it doesn’t know about installing and testing electrical systems isn’t worth knowing. Every question will be answered by the Megger Technical Team, and the best will be published in Professional Electrician. So, take advantage of the ‘every question answered’ guarantee today. Email your questions to: meggermeasures@hamerville.co.uk

You ask: I’VE HAD A FEW PROBLEMS RECENTLY WITH HOT SPOTS IN ELECTRICAL INSTALLATIONS WHERE, FOR EXAMPLE, TERMINALS HAVEN’T BEEN PROPERLY TIGHTENED. IS THERE AN EASY WAY OF DETECTING THESE?

Megger says: Yes, there is. Take a look at the new Megger VF-T5. It’s a handy gadget that’s not much bigger than a pen but it combines the functions of a non-contact voltage detector with a laser infrared thermometer. When you’re measuring temperature, the VF-T5 emits a laser beam. You simply point this at the spot you’re interested in and read the temperature on the display. It works over a temperature range of -30 to +280ºC, which covers everything you’re likely to need when checking electrical installations. As a volt finder, it has two ranges: 12 to 1,000 V, and 100 to 1,000 V. For both ranges, the volt finder’s LED changes colour and its buzzer sounds when it’s brought near a voltage source. The low voltage range has an extra feature: the LED flashes and the buzzer beeps, with the flashing and beeping getting faster as you get nearer the voltage source. Another benefit is that the VF-T5 has a bright built-in torch which is very convenient when you’re working in dark corners and cupboards.

It’s only a tiny instrument – it’ll fit easily into your pocket – but it’s incredibly versatile and, with IP54 ingress protection and a CAT IV 1,000 V safety rating, it’s safe to use anywhere.

You’ve previously described installations as becoming “dynamic energy hubs”. From an installer’s perspective, what are the biggest changes electricians are seeing on-site as electrification gathers pace?

Q

The biggest change is the pace of it all.

Electricians are now working in an environment where technology is moving quickly, while safety requirements and regulations continue to evolve. That creates a very different landscape to the one many installers have been used to.

Rising energy prices are also changing how homeowners view their properties.

Customers are far more aware of energy use and are actively looking to reduce

running costs, whether through EV charging, solar PV, battery storage or other technologies that support more effective energy management.

On-site, this means greater complexity.

Installers are no longer simply fitting a consumer unit for a standard domestic load. They’re increasingly integrating multiple technologies, often from different manufacturers, into a single installation.

As a result, the electrician’s role is broadening – requiring a clear understanding of how systems work together safely, compliantly and with future adaptability in mind.

With budgets often tight, how can contractors make the case for installing larger or higher-capacity consumer units now, even if EV charging or solar isn’t part of the current project?

Q

The key point is that moving to a larger consumer unit does not usually represent a major cost increase, particularly in the context of the overall job. Labour, cabling and protective devices typically account for a larger share of project costs than the enclosure itself.

Specifying a larger board and leaving spare ways blanked off is therefore a relatively low-cost way of futureproofing the installation. It gives homeowners flexibility for later additions, such as EV charging, solar PV or battery storage.

Historically, installers might have allowed around 10-20% spare capacity.

Now, where future upgrades are likely,

many electricians are allowing closer to 30-40%. This can prove far more cost-effective than returning later to carry out a full upgrade simply because the original board has no capacity left.

When adding EV chargers, heat pumps or PV to existing properties, what are the most common limitations electricians encounter with older consumer units?

Q

The main limitations are typically the age and condition of the installation, along with a lack of physical space or electrical capacity. Older consumer units were not designed with today’s electrification demands in mind, so they can quickly become a constraint when new technologies are introduced.

There is also an element of uncertainty.

Once an older installation is opened up, the condition of wiring, circuit arrangement and overall suitability all need to be assessed, which introduces risk.

For this reason, the preferred approach is often either a full consumer unit replacement, with appropriate testing, or the installation of a dedicated secondary unit for new technologies. Both options provide a safer and more practical solution than trying to adapt an existing board that may already be at its limit.

CIRCUIT PROTECTION

With multiple technologies now interacting in one installation, how should installers be thinking differently about protection, selectivity and surge protection?

Q

The starting point has to be a full understanding of the installation as a whole. In more traditional domestic setups, protection design may have been relatively straightforward.

However, once EV charging, PV and battery storage are introduced, the system becomes far more dynamic.

Installers need to consider the incoming supply, existing installation, overall power usage and the type and location of connected equipment. They must also assess likely demand and how generation or storage will interact with the wider system.

With that complete picture, protection design – including selectivity and surge protection – can be defined more effectively, while taking account of manufacturers’ recommendations. The key shift is that the consumer unit can no longer be viewed in isolation; it must be considered as part of a broader, integrated energy system.

Consumer units are often fitted in tight spaces. What design features make a real difference to installers in terms of speed and ease of installation?

Q

Practical design details can have a significant impact, particularly in confined domestic spaces such as cupboards or utility rooms.

Well-positioned knockouts improve cable entry and reduce awkward routing, while good fixing positions are essential where access is limited. A removable DIN rail can also make a big difference, allowing easier cable dressing and more working space during installation.

Features such as easy strike-out knockouts help save time, and standoff kits support more efficient cable routing without additional components. Even details like a well-designed lid retainer are important, making labelling and fault finding simpler once the unit is in place.

Individually these may seem minor, but collectively they can significantly improve installation speed, finish and usability.

Modern domestic boards can now contain dozens of circuits and multiple energy technologies. Is domestic distribution starting to resemble small commercial installations?

Q

In some respects, yes. Domestic installations are becoming more sophisticated, and the design approach is beginning to reflect aspects of smaller commercial systems.

Interestingly, overall household energy consumption may be decreasing in some areas due to more efficient appliances, improved insulation and the widespread adoption of LED lighting. However, the number of circuits and the level of control expected within the home are increasing.

Homeowners want greater flexibility – the ability to isolate circuits, add technologies and, in some cases, monitor energy usage more closely. While domestic systems remain distinct from commercial installations, distribution design is becoming more advanced, with a growing number of ways within boards.

Looking ahead, what technologies or electrical demands should installers be planning for now when specifying consumer units for new builds or major upgrades?

Q

Electric vehicle charging is a key consideration. Even if it is not immediately required, it is increasingly likely to form part of a property’s future electrical demand.

Installers should also consider the potential for solar PV and battery storage, particularly where roof space allows.

Heating is another important factor, as the shift towards low-carbon solutions may involve fully electric systems or conversion to air source heat pumps – both of which can significantly affect circuit requirements and overall capacity.

Ultimately, specification should not focus solely on current demand, but on what the installation may need to support in the coming years.

Allowing for future technologies at the outset is often the most practical way to create a system that is adaptable and ready for the direction of travel.

A SURGE IN DEMAND

From fully populated consumer units to individual protective devices, the conversation around electrical installations continues to evolve. Here the experts at Contactum explain why safety and compliance should always be key considerations.

M

odern day electricians are balancing regulatory compliance, best practice guidance, customer expectations and commercial efficiency – all while ensuring installations are safe, future-ready and professionally executed. The 18th Edition of BS 7671, including Amendment 2, has reinforced a clear direction of travel: enhanced protection is no longer a niche consideration but a core expectation.

Whether through the use of RCBOs to minimise unwanted tripping and improve circuit discrimination, next-generation devices to manage bi-directional current flow, AFDDs to mitigate the risk of arc faults, or SPDs to guard against transient overvoltages, modern consumer units are increasingly defined by integrated protective technologies.

The rise of integrated SPDs Across the electrical industry, one trend has become impossible to ignore. Surge Protection Devices (SPDs) have moved from being an optional add-on to a standard expectation in modern consumer units. Over the past two years in particular, the shift toward integrated SPD solutions has accelerated, driven by regulatory clarity, installer preference, and the growing sensitivity of the equipment found in today’s homes.

A surge is a fast, short-duration electrical transient – a sudden spike in voltage or current that lasts only milliseconds but can cause significant damage. These spikes can originate from everyday switching events, where stored energy is released back into the system, or from external sources such as lightning.

While switching-related surges are smaller, they occur frequently and can gradually degrade connected equipment.

Lightning-induced surges, although less common, can be extremely destructive and can enter an installation indirectly through buried cables, even when the building itself is not struck.

This matters because modern homes are filled with devices that are far more sensitive to transient overvoltages than the appliances of the past. EV chargers, solar inverters, smart heating controls, home office equipment, and entertainment systems all rely on delicate electronics that can be compromised by even minor surges.

A correctly specified and installed SPD diverts excess energy safely to earth, protecting both the installation wiring and

060_PE_MAY26_Layout 1 08/04/2026 17:15 Page 61

the equipment connected to it. As the value and complexity of domestic electrical systems increase, so does the need for reliable surge protection.

Regulation has played a major role in making SPDs standard practice. The 18th Edition, including Amendment 2, made the industry’s direction clear. Regulation 443.4.1 states that protection against transient overvoltages shall be provided where the consequences could result in serious injury, loss of life, failure of a safety service, or significant financial or data loss.

For all other situations, SPDs must be installed unless the client formally declines and accepts the associated risk. In reality, very few clients are willing to take that responsibility, and installers increasingly view SPDs as the default requirement for compliance and peace-of-mind.

This regulatory clarity has coincided with a strong market transition to consumer units that include SPDs as standard. Over the past two years, installers have shown a clear preference for integrated SPD solutions rather than retrofitted devices.

Integrated units simplify installation, reduce wiring complexity, and provide a cleaner, more compact layout. They also give installers confidence that the SPD is correctly matched and coordinated with the consumer unit – something that can be more challenging when mixing components from different sources.

The result is a faster, neater and more reliable installation that aligns with both regulatory expectations and customer demand.

Contactum’s Defender range reflects this trend directly. Designed for modern domestic and light commercial installations, Defender 2.0 offers consumer units with integrated Type 2 SPDs, giving installers a ready-made solution that meets today’s requirements without adding complexity.

The range provides generous wiring space, a clean internal layout, and a robust enclosure built for real world conditions.

By offering SPD-integrated models as part of its core line-up, and by developing new SPD solutions across both single- and

three-phase offerings, Contactum is helping to support installers in delivering compliant, future-ready installations.

Incorporating safety from the start As electrical installations continue to evolve, the wider principle remains consistent – protection should be designed in, not retrofitted.

Whether the focus is on surge protection, arc fault detection or individual circuit protection through RCBOs, today’s best practice centres on delivering resilient, regulation-aligned consumer units that reflect how properties are used.

SPDs are just one element of that broader safety landscape, but they clearly illustrate how regulatory change, technological advancement and installer experience combine to shape modern installation standards.

A TEST OF THE METAL

Umer Farooq, Technical Product Manager at Live Electrical Distribution UK, gives some insight into the thought process behind the design of the brand’s SRN consumer unit range.

E

fficiency, reliability and consistency remain key priorities for electrical contractors working across residential and light commercial installations. As project timelines tighten and labour efficiency becomes increasingly important, distribution equipment that simplifies installation can provide valuable advantages on-site.

Live Electrical’s SRN range of metal consumer units has been developed with installation efficiency as a central design focus. Rather than concentrating purely on enclosure construction, the range adopts a system-led approach that combines a streamlined internal layout with simplified circuit connection methods.

The result is a consumer unit designed to reduce installation time while maintaining the performance and compliance expected of modern distribution equipment.

Suitable for both surface-mounted and recessed (flush-mounted) installations, the SRN range can be used across a wide variety of domestic and light commercial projects throughout the UK.

Enclosure ensures practical installation The SRN enclosure is manufactured from robust non-combustible steel, delivering the mechanical strength and fire performance required under current installation standards.

Multiple cable knockouts are positioned around the enclosure, including the rear panel, allowing cables to enter from different directions depending on site layout and routing.

This flexibility can be particularly useful when working within confined spaces, helping installers organise cable entry and reduce congestion within the board.

Each consumer unit is supplied with a DIN rail and earth terminal bar, allowing installers to begin assembly immediately.

Internal spacing has been arranged to provide clear access for wiring, helping maintain an organised layout that also supports simple inspection and testing.

a cleaner internal layout, helping speed up installation while also improving accessibility for inspection, testing and maintenance.

Integrated live and busbar system Complementing the RCBO design is the SRN range’s integrated 100 A copper busbar system.

This assembly distributes both live and neutral conductors through a single compact structure, connecting the main switch and all RCBOs without the need for additional neutral wiring.

RCBOs can be installed directly onto the busbar, allowing the board to be assembled quickly and efficiently while maintaining a tidy internal arrangement.

RCBOs without fly neutral leads A key feature of the SRN system is the use of the RNC series single-module double-pole RCBOs, designed without traditional fly neutral leads.

In conventional consumer units, RCBOs often include flexible neutral leads that must be individually connected to the neutral bar. As circuit numbers increase, these extra conductors can accumulate inside the enclosure, creating wiring congestion and slowing installation.

By eliminating the fly neutral lead, the SRN system simplifies internal wiring.

Both the live and neutral conductors of each circuit are terminated directly into the RCBO. This reduces the number of conductors within the enclosure and creates

Modular busbar scalability The busbar architecture is also modular, allowing additional sections to be joined simply by sliding them together. This enables installers to configure boards for different circuit requirements using the same system platform.

By addressing common installation challenges such as wiring congestion and circuit termination efficiency, the SRN range demonstrates how thoughtful engineering can support faster and more organised installations without compromising safety, compliance or reliability.

DUTY OF CARE As part of a recent safety-critical electrical refurbishment in a care home, outdated distribution boards were replaced with new Proteus Switchgear consumer units that offer enhanced protection. We get the full details of the project.

G

&M Electrics, based in South Wales, recently undertook a full EICR across a care home facility. The care service, which provides bespoke, community-based support to older individuals with physical and mental health conditions, needed major electrical upgrades including 17 x consumer units with AFDDs and 2 x 3-phase distribution boards.

During the routine inspection, it was identified that the existing electrical distribution boards comprising of both single phase and three phase units were outdated and non-compliant with current electrical wiring regulations.

Many of the boards had been in place for over 30 years and were showing clear signs of wear, including faulty doors and an inability to meet modern safety standards.

The electrical contractor, G&M Electrics, was unable to source compatible spare parts, reinforcing the need for a full upgrade.

Board decision To address this, G&M Electrics specified and installed 17 of Proteus Switchgear’s brand new single phase consumer units. Following an initial introduction from a locally based wholesaler, Proteus Sales Development Manager, Adam Cole, was able to introduce the company to the new offering.

Proteus consumer units were selected for a combination of safety, compliance, and installer friendly features. A key factor in the selection was the inclusion of a flush fitting door which is also removable to ease labelling the circuits of the board.

The removable blank on the door allowed for the installation of key locks in the doors across all 17 units, ensuring access could be restricted in line with

health and safety protocols.

From a technical standpoint, the availability of Proteus’ busbar mounted single module Surge Protection Device (SPD) simplifies the installation while maintaining a compact footprint. In addition, bidirectional RCBOs and single module AFDDs are readily available, ensuring compliance with Regulation 421.1.7 of BS 7671, which mandates the use of AFDDs on socket-outlet circuits not exceeding 32 A in certain high-risk premises, with care homes being one. As the care home houses vulnerable individuals, this level of protection was deemed essential.

To fulfil the 3-phase equipment required in shared utility areas and kitchens, two Proteus 3-phase distribution boards were also installed, ensuring brand consistency and simplifying future maintenance.

The successful collaboration between wholesaler, G&M Electrics and Proteus has demonstrated the value of quality product design, professional installation, and prioritising safety in care environments.

CIRCUIT PROTECTION

IT’S A SMALL WORLD What are the biggest engineering challenges when reducing the footprint of protection and distribution equipment?

Q

Matteo Crespi, SVP Power Products Europe Hub at Schneider Electric, answers some key questions around the challenges brands are facing as installations continue to require bigger performance from smaller solutions.

66 May 2026

PROFESSIONAL ELECTRICIAN

Across both residential and commercial installations, electricians are increasingly being asked to fit more circuits and protection devices into limited space. What’s driving this trend?

Q

We’re seeing a structural shift in building requirements, driven by electrification, energy efficiency, and evolving safety standards. Electrification is increasing the number of loads requiring dedicated circuits. Technologies such as EV charging, heat pumps and smart systems all demand additional protection, often within unchanged panel space.

At the same time, high energy costs and efficiency targets are driving demand for smarter electrical panels. Regulation is tightening, and homeowners are pushing this too – our research shows 84% rank energy efficiency as their top home improvement priority, while 24% already use smart lighting.

This growth in smart and low-carbon technologies increases complexity at the point of distribution. More circuits, segregation and protection are needed, often within the same footprint. This is especially challenging in retrofit projects, where electricians must work within legacy enclosures designed for older demands.

With around 80% of UK buildings expected to still be in use by 2050, retrofit will dominate.

Making equipment smaller is far from simple. As footprint reduces, power density increases and thermal margins shrink.

Managing heat, maintaining insulation, and containing faults all become more difficult. At the same time, compliance with BS, IEC and IEEE standards remains essential, including clearance distances and fault performance.

This means innovation goes beyond miniaturisation. It requires advances in materials, design and system architecture.

There’s also the challenge of integration. Modern equipment must combine power handling with digital protection and communication systems in compact enclosures, without compromising reliability or service life.

How is electrification influencing the design of modern consumer units and distribution boards?

Q

Electrification is transforming distribution boards from static hardware into flexible, intelligent platforms.

New technologies bring higher and more variable loads, along with increasing use of DC systems in homes – from EV charging to battery storage and PV. This creates new requirements around protection, isolation and compatibility in hybrid AC/DC environments.

As a result, more granular, circuit-level protection is needed to contain faults and avoid wider disruption.

Load profiles are also changing. Boards must now support bidirectional power flow, smart load management and integration with control systems, rather than simply distributing power one way.

Upgradeability is becoming essential, particularly for retrofit. Systems must allow safe expansion and reconfiguration without major disruption.

066_PE_MAY26_Layout 1 08/04/2026 17:30 Page 67

At the same time electricians need solutions that are quick to install, easy to commission and inherently compliant.

Space constraints are especially challenging in retrofit projects.

How is Schneider Electric helping contractors upgrade installations?

Q

Retrofit is where the energy transition becomes most complex. Many existing panels were not designed for today’s loads, and replacing them can be costly and disruptive.

Our approach is to reduce that friction by freeing up space within existing enclosures, while maintaining high protection standards. This allows contractors to upgrade systems without major structural changes.

How do compact solutions like the PowerPact 4 ComPacT NSXm powerboard address these challenges?

Q

Products like the PowerPact 4 ComPacT NSXm are designed to help contractors fit more distribution into less space without compromising safety or flexibility.

Its slim, wall-mounted design makes it well suited to space-constrained commercial and industrial environments. At the same time, it’s engineered for ease of installation and maintenance, with improved access and reduced installation time.

Built-in protection features, including surge protection, enhance safety, while visible status indication allows checks without opening the unit.

Despite its compact size, it remains flexible. It supports a range of configurations and load requirements, and simplifies wiring and metering to speed up installation.

Will demand for compact distribution equipment continue to grow, and where is innovation focused?

Q

Yes – the drivers are long-term. Electrification

is accelerating, energy efficiency upgrades are increasing, and expectations around safety and continuity are rising. As EV charging and low-carbon heating expand, electricians will need to add more circuits and functionality within the same footprint.

Our focus is on delivering higher performance in smaller form factors, particularly for retrofit, where avoiding enclosure upgrades is key. We’re also prioritising more selective, circuit-level protection to minimise disruption by isolating only affected circuits – critical in both homes and commercial settings.

Finally, we’re investing in digital tools that support faster, more accurate design and configuration, helping electricians and panel builders deliver compliant systems more efficiently.

How does the KCM Classic AFDD work?

An Arc Fault Detection Device, or AFDD, is a protective device designed to identify and respond to dangerous electrical arcing within a circuit.

Electrical arcing can occur where there are damaged conductors, loose connections, crushed cables, or deteriorated insulation. Unlike overloads or short circuits, arc faults may not produce enough current to trip traditional protective devices such as MCBs or RCDs. An AFDD continuously monitors the electrical waveform and is able to recognise the unique signature of a hazardous arc. When detected, the device automatically disconnects the supply to prevent the fault from developing into a potential fire risk.

By targeting faults that conventional protection may not identify, AFDDs provide an additional layer of safety within modern electrical installations.

emphasis on premises where the consequences of fire may be greater, including residential buildings, HMOs, student accommodation, and care environments. In these settings, early arc fault detection can play a critical role in improving overall electrical safety.

The availability of AFDD protection within the MEM family supports installers working across these sectors, providing a practical route to compliance while maintaining installation efficiency.

DO MCBS EXIST? If you’re new to the electrical industry, understanding MCBs is an essential starting point, as Martin Plumbridge – TMIET, Technical Manager at Doepke UK, explains.

A

n MCB (Miniature Circuit Breaker) is an automatically operated electromechanical device designed to protect a circuit from overcurrent conditions and short-circuit faults. Unlike fuses, which require replacement after operation, an MCB can be reset once the fault has been cleared. An MCB is a commonly used generic term that does not appear in BS 7671 or the relevant product standards, where the correct term is circuit breaker.

Circuit breakers There are two product standards for CBs – BS EN 60898-1 and BS EN 60947-2. CBs to BS EN 60898-1, commonly referred to as MCBs, have fixed characteristics with ratings up to and including <63 A and are suitable for operation by “ordinary persons”. After breaking a short circuit, you must be able to reset the CB. The second standard, BS EN 60947-2, covers CBs with adjustable characteristics and ratings up to 1,600 A. These CBs are to be used by “instructed persons” and may not be suitable for reuse after breaking a short circuit.

70 May 2026

PROFESSIONAL ELECTRICIAN

Short circuit breaking capacity To meet BS EN 60898-1, the ICN (rated short-service capacity) must be printed on the front of the MCB, e.g. 10 kA. This represents the maximum short-circuit current the MCB can safely interrupt twice and still resume normal service when reset. There are additional short circuit breaking requirements at 75% of the ICN and a multiple of the rated current.

For circuit breakers to BS EN 60947-2, two breaking capacities are defined: Icu (ultimate breaking capacity) and Ics, which is expressed as a percentage of Icu, typically between 25% and 100% selected by the manufacturer. Following a short circuit trip, the instructed person must follow the company’s maintenance policy before resetting the CB. Energy limiting MCBs BS EN 60898-1 classifies B and C characteristic MCBs up to and including 63 A into energy-limiting classes 1 or 3. In the event of a short circuit, Class 3 MCBs offer superior performance by reducing the amount of let-through energy (I²t), thereby protecting downstream cables and components.

Tripping curves Tripping characteristic curves, issued by the manufacturer, illustrate the relationship between the current flowing through an MCB and the time taken for the breaker to trip. These curves ensure correct protection against both overcurrent and short-circuit conditions.

MCBs to BS EN 60898-1 are classified according to their tripping characteristics, commonly known as B, C and D curves.

General tripping characteristics for B and C curve MCBs can be found in BS 7671 Appendix 3. (D curves are not recognised for use in domestic applications.)

the coil (electromagnet). When a short circuit occurs, a large magnetic field is created in the coil due to the high current flowing through the MCB. This causes the latch to be triggered. Due to the rapid tripping, the electromagnetic release is also referred to as instantaneous release.

Overcurrent and short circuit release MCBs have two independent releases: 1. Thermal release (delayed release) 2. Magnetic release (instantaneous release) Thermal release Tripping in the delayed overload range occurs via a bimetal element that deflects as current flows through the MCB. The

time taken to trip depends on the magnitude of the overcurrent. If the current remains below the rated current of the MCB, no tripping occurs. Once the tripping current is exceeded, delayed tripping takes place.

Magnetic release The current flowing through the MCB generates a permanent magnetic field in

Conclusion An MCB is a commonly used generic term that does not appear in BS 7671 or the relevant product standards, where the correct term is circuit breaker.

Circuit breakers are designed to either BS EN 60898-1, for operation by ordinary persons (commonly referred to as MCBs), or BS EN 60947-2, for use by instructed persons (often referred to as MCCBs).

THE CHOICE IS YOURS Here we find out more about how and why Elucian consumer units are giving contractors more choice and flexibility.

I

n a market shaped by tighter regulations, higher customer expectations and increasing demand for reliability, the consumer unit has become far more than a basic distribution board.

Electricians are looking for flexibility, compliance, ease of installation and long-term performance as standard.

Since launching in 2021, Elucian has steadily built a reputation for being practical, installer-friendly and genuinely designed around the needs of the people fitting them day in, day out.

Contractor focussed One of the key reasons behind the success of the Elucian range lies in its contractor-led design philosophy. Elucian consumer units are engineered to address the practical challenges electricians face on-site – from tight installation spaces to increasingly complex circuit protection requirements.

Elucian covers single-phase solutions for residential and small commercial projects, alongside robust three-phase options designed to meet the demands of larger commercial installations. This breadth allows contractors to remain consistent with product selection across varied project types, simplifying specification and installation.

Built for compliance and future readiness With the ongoing emphasis on safety and compliance, consumer units must deliver confidence both today and in the future.

Elucian units are designed to support modern protective devices and configurations, enabling installers to meet current standards while remaining adaptable to evolving requirements.

This focus on future-proofing has been reinforced through recent product launches, which have expanded the range and enhanced its flexibility. These include:

Type B HP bi-directional RCCB The new Type B Heat Pump (HP) Bi-Directional RCCB is designed to offer enhanced protection for modern installations where high-frequency leakage currents are more common.

While a standard Type B RCCB detects DC leakage from 0 Hz and AC leakage up to 1 kHz, the new Type B HP extends detection up to 20 kHz, offering far broader protection for today’s inverter-driven technologies. This makes it ideal for preventing electric shock and reducing fire risk in advanced systems where standard devices may not detect

certain leakage types.

Key features include: ● Detects leakage up to 20 kHz ● True DC detection from 0 Hz ● Designed for inverter-driven loads ● Minimum tripping threshold of 150 mA above 1 kHz It is suitable for EV chargers, heat pumps, HVAC systems, lifts, pumps, CNC machinery and more. It integrates seamlessly with Elucian consumer units and three-phase boards.

10 kA 3 pole + switched neutral bi-directional RCBO The 10 kA 3 Pole + Switched Neutral Bi-Directional RCBO has been developed in response to growing demand for compact, compliant protection in three-phase environments.

TAPE IT EASY Steve Kaye, Marketing Manager at Forum, looks at why it’s time to say ‘goodbye’ to cables and ‘hello’ to control thanks to the latest innovations in LED tape lighting.

L

ED tape lighting is now a staple of modern residential design, used extensively beneath kitchen and bathroom units, within media walls, and as feature lighting throughout the home. While LED tape technology itself has advanced in terms of efficiency, colour control and flexibility, the methods used to control it have often lagged behind. Products have typically required bulky controllers, complex wiring or unintuitive interfaces that add time and cost to an installation.

Take control In response to this gap in the market, Forum Lighting Solutions has introduced an innovative new range of 12-24 V wireless controllers and battery-powered RF switches.

Designed to work seamlessly with single colour, CCT and RGB+CCT LED tape, the range delivers a genuinely simple, flexible and future-proof control solution that meets the needs of installers, wholesalers and end users alike.

At the heart of the range is the compact

12-24 V wireless controller, which is approximately half the size of most traditional LED controllers, allowing it to be discreetly installed in confined spaces such as cupboards, ceiling voids or behind furniture.

We’ve deliberately simplified the installation by creating clearly labelled, push-fit terminals, significantly reducing wiring time and minimising the risk of errors on-site.

A built-in green status LED provides immediate visual confirmation that power is connected, and the LED tape is operating correctly – an invaluable feature during commissioning and fault-finding.

The Ra switch on the controller allows easy local control of connected LED tape.

This switch sets the minimum dimming of the tape, ensuring no flickering takes place.

In addition to App-based functionality the controllers are also RF-enabled, allowing them to be paired with Forum’s new battery-powered wireless RF switches. These switches provide instant, tactile control without the need for wiring, making them ideal for retrofit applications.

A single press controls on/off, a long

press enables smooth dimming and a double press accesses CCT or RGB functions.

Supplied with high-quality cell batteries offering a lifespan of at least five years, the switches are available in 1, 2 or 3 gang formats, finished in either matt white or matt black. As no wiring or drilling is required, they can be mounted virtually anywhere, offering complete flexibility in placement.

Get connected Once installed, lighting control becomes effortless. The controllers connect wirelessly to the Tuya smart App, which is fully compatible with Amazon Alexa and Google Home. Through the App, users can switch lights on and off, dim output, adjust colour temperature and control RGB colours with ease.

The interface is intuitive and user-friendly, making smart lighting accessible, even to first-time users.

Timers and scenes can be programmed quickly, while full voice control adds further convenience for everyday use.

By combining compact design, wireless flexibility, smart-home compatibility and true ease of installation, our 12-24 V wireless controller range represents a significant step forward in LED tape control.

The range is fully supported with detailed technical specifications in the Forum Edition 11.1 catalogue.

OUT WITH THE OLD

T

ake a look in your toolbox. Be honest! How many tools in there are worn, duplicated or just taking up space because ‘they’ve always been there’?

Most tradespeople build their kit over years and before you know it, you’re lugging around a metal box that weighs as much as a small generator and still doesn’t have what you need when you’re in a hurry. If this sounds familiar, it’s time for a seasonal clear-out.

Here are five swaps worth considering:

If your toolbox is full but never quite has what you need, it’s time for a reset. Jason Cunningham, Product & Technical Support at KNIPEX, has five easy swaps to make your kit leaner and more efficient.

5

1. Ditch the metal box Traditional metal toolboxes are tough but they’re not always practical. They’re heavy, awkward on stairs and usually end up as a bottomless pit of tangled kit.

The KNIPEX Modular X18 tool backpack offers a more organised approach. It opens fully at the front and back, so you can actually see what you’re carrying.

Inside, there are 21 retaining loops and 37 pockets, plus separate compartments for tools, test equipment or a tablet.

The waterproof moulded base keeps it upright on-site and the durable recycled fabric is splash-proof and easy to clean.

Add in MOLLE webbing and FIDLOCK connectors for attaching accessories, and you’ve got a setup that adapts as your kit evolves. It’s also really comfortable to carry around from job-to-job.

4 2. Get set Water pump pliers are one of those essentials that end up in every kit and often come in different sizes. But carrying three loose pairs, all knocking together at the bottom of the bag, isn’t exactly organised. Tool rolls are your friend.

The KNIPEX Cobra Water Pump Pliers, which self-lock, grip securely without slipping and have a fine adjustment for precise sizing, are available in durable polyester tool rolls that keep each size protected and easy to grab. The S9 three-piece set includes 150, 250 and 300

mm pliers. Ideal for tight spaces through to larger pipework, the S8 three-piece set covers 125 to 250 mm while the five-piece set has sizes from 125 to 300 mm.

If you prefer to build your own kit, empty Cobra rolls are available in four or six-compartment versions, keeping everything neat and ready.

3. Cut down the collections How many metric and imperial spanners do you have? The KNIPEX Pliers Wrench can replace a full set. It combines pliers and wrench functionality in one tool, with

078_PE_MAY26_Layout 1 08/04/2026 18:05 Page 79

2 smooth, parallel jaws that grip without damaging plated fittings.

You can work directly on chrome without leaving marks, push-button adjustment makes sizing quick and accurate and the parallel jaws provide a solid, backlash-free grip. It’s ideal for gripping, holding, pressing and bending, while the ratchet-like principle speeds up tightening and release.

4. Upgrade tired pipe cutters Old pipe cutters can be hard work. Blunt wheels, awkward adjustments and limited access in tight spaces slow everything down. The KNIPEX TubiX family solves those issues.

The TubiX has a QuickLock one-hand locking mechanism, allowing independent holding and clamping on the pipe.

Needle bearings on the cutting wheel and guide rollers make for smoother cuts and a spare cutting wheel is stored neatly in the handle. It cuts copper, brass and stainless steel pipes from 6-35 mm in diameter up to 2 mm wall thickness.

If you’re working in tighter areas, the compact TubiX S is designed for minimal cutting circles and fits comfortably in your pocket, cutting pipes from 3-30 mm. For larger jobs, the TubiX XL handles pipes up to 76 mm diameter.

5. Personalise and organise On busy sites, tools have a habit of wandering. When several trades are working side-by-side, it’s easy for grips or cutters to get mixed up.

The KNIPEXtend ColourCode Clips offer a simple solution.

These clip into KNIPEX tools with comfort handles via the KNIPEXtend interface and come in five colours, meaning you can mark tools for personal identification or group them by task – red for cutting, blue for gripping, for example. It’s a small tweak, but it saves time rummaging around and reduces the risk of kit going missing.

Organising your tools, replacing duplicated spanners with a Pliers Wrench, upgrading old cutters or swapping a metal box for a modular backpack all add up to a leaner, more efficient kit.

So, next time you’re hauling your kit on to site, ask yourself: does every tool in there deserve its place?

RETURN TO TENDER

Jason Cooney, Director of Tsaks Consulting UK – a London-based bid and tender writing consultancy, advises contractors on how to overcome some of the more recently emerging challenges when attempting to win tenders and bids.

F

or most electrical contractors, completing the ‘technical’ side of a tender is relatively straightforward. You know the scope of the job, your capacity, pricing and regulations. That used to be all you needed to win a spot on a government panel, framework or DPS, however it’s no longer the case. The requirements and goalposts are moving and it’s due to the recent implementation of the Procurement Act 2023.

A key challenge for most electricians and other contractors is positioning yourself as the Most Advantageous Tender (MAT).

It was formerly the Most Economically Advantageous Tender (MEAT), which meant your expertise and a competitive price could get you over the line.

In 2026, if you aren’t scoring high on ‘social value’ and ‘net zero’, your chances of winning a government bid or contract are minimal.

80 May 2026

PROFESSIONAL ELECTRICIAN

The social value challenge Public sector buyers, such as government departments and trusts, are now legally encouraged to consider social benefits when procuring suppliers and service providers.

That means, in addition to being confident that you can complete a rewiring project or EV charger installation, they also want to know that you will ensure the downstream benefits of the project will flow through to the local community. Supporting local businesses and employment is critical and you need a credible plan to deliver this.

“In 2026, if you aren’t scoring high on ‘social value’ or ‘net zero’, your chances of winning a bid are minimal....”

Social value usually equates to between 10% and 30% of the total weighting criteria. This is a substantial amount and has a significant impact on the outcome of the bid. Putting forward a generic plan with marketing terminology and a general commitment to the local area will generally see you scoring low.

You need to put forward a specific, measurable set of objectives and actions to convince procurement teams that you will deliver. Everything needs to be quantified and tailored to the specific social value map of the local area you propose to operate in.

For example, you can’t state that ‘if we win this contract, we’ll hire locals to complete part of the works’. This is a generic statement and your commitment isn’t quantified.

Instead, you need to state how many locals you plan to hire, if they will be apprentices, what role they will undertake and through what avenues you plan to

080_PE_MAY26_Layout 1 08/04/2026 18:15 Page 81

recruit them. You’ll also need to put forward a percentage of total supplies and works undertaken by locals (or purchased from local suppliers).

The net zero requirement (PPN 06/21) challenge In the case of larger electrical contractors who are chasing contracts over £5 million, a Carbon Reduction Plan (CRP) is a mandatory pass/fail requirement under PPN 06/21. Even for smaller contracts, they take a more active and detailed approach to reviewing your environmental policy.

Net zero is no longer a box-ticking exercise which you go through to pass.

You need to show that you understand scope 1, 2 and 3 emissions to score well as well as demonstrating that your environmental policy and actions are integrated throughout your operations.

For example, demonstrating that your carbon intensity has been reducing, and that you’re implementing a fleet transition, or innovation from an IT perspective to

case study to show what you’ve delivered. This may be electrical works at a previous project (preferably a government project). ● Explain. You need to clearly explain what you delivered and how it applies to the proposed project.

ensure you use your fleet efficiently, is critical to scoring well and showing real progress and commitment to net zero.

Final thoughts To score well in both social value and net zero, electrical contractors must prove that they take both seriously and have put concrete initiatives in place to support locals and to move towards achieving net zero.

By putting forward an achievable plan and measurable objectives that you can action, you can score well in this area and don’t have to win by compromising on price.

Evidence is the ultimate key to winning electrical tenders One of the biggest challenges in writing your bid is to avoid writing ‘marketing fluff’. Procurement teams can see straight through it, and it frustrates them.

A fool-proof way to approach it is to break each section or point down into: ● Your point. Stating what you will do or what you have done. ● Evidence. This part is critical. You need a data point, reference, testimonial or

GET TRACKING

In response to ongoing industry focus on competence and compliance, we take a look at how electrician Ben Baker has developed a straightforward solution to one of the trade’s more frustrating admin tasks – logging CPD.

A

s an electrician in his late 40s, Cornwall-based Ben Baker isn’t your typical electrical industry entrant. In fact, he only qualified in October 2024 after retraining later in life. But it’s exactly that route into the sector – balancing learning, work, and family life – that led him to spot a problem many electricians will be familiar with.

“Tracking CPD felt harder than it should be,” Ben explains. “Most tools out there were too complicated, too expensive, or just not designed for how we actually work on-site.”

Like many in the trade, Ben found himself putting the process of logging CPD off altogether – not through lack of willingness, but because the process felt like a chore. That frustration became the starting point for what is now the CPD Progress Tracker App. Built from the tools up Ben’s is far from a slick tech start-up story.

He started developing the App on his wife’s old laptop, quickly running into limitations that forced him to upgrade just

to continue.

With no coding background, he relied heavily on learning as he went – including figuring out how to use AI tools to help build and structure the App. Development of the App itself was restarted three times from scratch. Each version improved on the last, ironing out issues and refining the user experience into something practical and reliable.

Ben says: “It wasn’t a case of pressing a button and getting an App. It involved constant iteration and problem-solving.

“I feel that most CPD tools are too admin heavy, so I wanted to create something that actually works in the real world.”

KEY FEATURES ● Simple and quick CPD entry ● Organisation by profession (including multiple professions) ● Ability to attach evidence (photos, files, QR scans) ● Clean export options for sharing records ● One-off purchase – no subscriptions

Designed for real-world use The result is an App that focuses on simplicity above all else. The CPD Progress Tracker is designed to make logging CPD quick and straightforward – something that can now realistically be done on-site, rather than left until the end of a long day.

Users can log CPD in seconds, organise records by profession, and even manage multiple roles within one App – ideal for those juggling different qualifications or working across sectors.

Evidence such as photos, files, and QR scans can be attached, and records can be exported cleanly when needed.

Importantly, the App follows a one-off purchase model (£3.99), avoiding ongoing subscription costs – another decision shaped by Ben’s own experience.

It’s a Tracker Ben firmly believes that what sets the App apart is its perspective. Rather than software designed in isolation, it’s been built around the realities of day-to-day electrical work.

That practical mind-set runs through every aspect of the App, from its clean interface to its flexible structure. It avoids the temptation to overload the user with features for the sake of it and instead it focuses on doing one job well.

With an iOS version already available and an Android release in progress, the CPD Progress Tracker looks set to offer a simple, trade-friendly alternative for electricians looking to stay on top of their professional development.

PRODUCTS IN PRACTICE

Aico reduces the risk for Flagship Housing When social housing provider Flagship Housing reviewed fire safety in homes fitted with modern ventilation systems, it identified a need to strengthen detection and improve visibility of compliance.

Working alongside Aico, the organisation has implemented a joined-up solution designed to address the specific risks associated with Positive Input Ventilation (PIV) and Mechanical Ventilation with Heat Recovery (MVHR) systems.

Managing more than 33,000 homes across the East of England, Flagship Housing continues to invest in both new-build and retrofit projects. As ventilation systems become more common to tackle damp and mould, attention has increasingly turned to how they interact with fire safety strategies.

Addressing a growing risk While PIV and MVHR systems offer clear benefits for indoor air quality, they can also introduce additional considerations in the event of a fire – particularly around ductwork, compartmentation and the potential for smoke to travel through a property.

86 May 2026

PROFESSIONAL ELECTRICIAN

Since joining Flagship Housing three years ago, Compliance Manager (Electrical), Davin Gee, has worked closely with Aico to develop a solution that responds to these challenges while aligning with current standards.

“We continuously look at ways to prioritise residents’ safety,” he explains.

“Increasing fire detection in properties with MVHR and PIV systems helps provide earlier warning and mitigates the risks linked to ventilation and smoke movement.”

The project focused on two key aims: improving life safety in properties with installed ventilation systems, and giving the housing provider real-time insight into alarm activity and compliance status.

A practical, integrated approach Rather than treating fire detection and ventilation as separate systems, the solution brings them together. Detection is extended into areas where ventilation equipment is located, ensuring coverage better reflects the intent of BS 5839-6.

At the same time, systems are configured so that when a fire alarm activates, the ventilation system is automatically isolated. This helps prevent smoke being drawn through ductwork and distributed around the property – one of the key risks identified.

Each property within the scheme is equipped with Aico’s Ei3024 multi-sensor alarms, alongside RadioLINK relay modules to trigger ventilation shutdown, and the Ei1000G Gateway to provide remote notifications and compliance data.

This combination not only improves protection for residents but also gives Flagship Housing immediate visibility if an alarm is triggered.

Delivered on-site Installation has been carried out by Karma Electrical & Fire Systems, an Aico Platinum Partner. Early installations were supported on-site to ensure consistency and establish best practice from the outset.

Karl Sharman, Managing Director at Karma Electrical & Fire Systems, said: “The Aico system is straightforward to install and integrates well with ventilation systems. It also provides far greater visibility of compliance and resident safety compared to standalone alarms.”

Initially rolled out across 150 homes with existing ventilation systems, the specification is now being adopted more widely. It will form the baseline standard for all new installations, as well as future retrofit projects.

Benefits reported so far include improved resident safety, reduced risk of smoke spread, stronger alignment with BS 5839-6, and immediate notification of alarm events. For Flagship Housing, the ability to monitor compliance in real time represents a significant step forward, supporting a more proactive approach to fire safety management.

Looking ahead The rollout across existing properties was expected to be completed by the end of last month with the approach already influencing future design standards across the organisation’s housing stock.

Reflecting on the project, Aico Relationship Manager, Trevor Sawyer, concluded: “By integrating detection, ventilation control and real-time data, Flagship Housing has taken a forward-thinking approach that puts residents first.”

Products round up

Turn downlight control on its head Innovation in downlighting has often followed a predictable path. Fittings become slimmer or more efficient, but the way installers interact with them rarely changes. All LED’s new Spartan Pro takes a different approach. Rather than refining what already exists, it rethinks one of the most frustrating parts of downlight installation: adjusting colour temperature.

Powered by RotaLens Technology, Spartan Pro introduces a new way to control light. Instead of removing the fitting to access a hidden switch, the installer simply rotates the lens to select the desired colour temperature. It is a straightforward mechanical action that shifts between 3000 K, 4000 K, and 6500 K while the fitting remains securely in the ceiling.

Removing risk

For electricians, this small change removes a familiar risk. There is no need to pull the downlight from the plaster, wrestle with high-tension springs, or disturb the ceiling finish. Adjustments can be made quickly and safely without damaging paintwork. For the end user, it means lighting can be adapted without disruption long after installation.

Beyond colour control, Spartan Pro provides flexibility through wattage selection. Installers can choose between 4 W and 6 W, delivering up to 755 lumens with efficiencies reaching 126 lumens per watt. This dual-output design reduces the

90 May 2026 PROFESSIONAL ELECTRICIAN

need to carry multiple fittings while allowing lighting levels to be tailored anytime. With a minimum ceiling void of less than 40 mm, the downlight is also suited to shallow ceiling spaces.

Practical installation remains a core focus. Spartan Pro uses a 2-part push-fit connector with loop-in and loop-out terminals, allowing wiring to be completed quickly. Enlarged terminals simplify connections, while the compact body supports efficient installation in both new builds and refurbishments.

Visually, Spartan Pro maintains a clean architectural appearance. The fitting features a 0.8 mm ultra-slim bezel – approximately the thickness of eight sheets of paper, creating a subtle finish. It remains compatible with Spartan’s snap-on bezels, supplied in Polar White as standard.

Additional finishes include Carbon Black, Satin Nickel, Polished Chrome, Anthracite, Antique Brass, Brushed Brass and Polished Brass, providing design choice without changing the fitting.

While Spartan Pro introduces a new adjustment mechanism, it builds on the strengths of the original Spartan range.

The fitting remains fully fire-rated across multiple constructions, tested for 30, 60, and 90 minutes in timber joists, 30 and 90 minutes in I-joists, and 30 minutes in metal web joists. Compliance with Part B, Part C, Part E, and Part L ensures the fitting is ready for modern building requirements.

Spartan Pro is also IP44 rated for protection against splashing water, making it suitable for kitchens and bathrooms, while remaining fully insulation coverable to support installation within modern airtight construction methods.

Products round up

Unicrimp strengthens Q Crimp Fixings range with major new additions Unicrimp has expanded its Q Crimp Fixings range with two product launches – Bullfix heavy duty plasterboard fixings and the Plus Series high performance woodscrews – alongside a wide selection of new lines and size extensions.

The new Bullfix range delivers high load-bearing performance for plasterboard applications, supporting up to 133 kg while offering a simple five-step installation process.

The Plus Series woodscrews are engineered for strength and speed, removing the need for pre-drilling in most applications while providing enhanced corrosion resistance and compliance with EN14592.

Further additions across the range reinforce Unicrimp’s position as a one-stop fixings supplier for professional installers, supported by a newly produced Fixings brochure.

Bullfix: high strength plasterboard fixing

Bullfix has been designed to provide secure, reliable fixing for heavy loads in plasterboard. Its patented smart wing design ensures a tight hold across common board types, including stud walls, dot and dab, and insulated plasterboard (12.5-16 mm).

Two options are available: ● Bullfix Heavy Duty – supports up to 116 kg with a 7 mm cavity ● Bullfix Heavy Duty Extra – supports up to 133 kg with a 20 mm cavity

Installation is straightforward: drill, insert the collar, push in the fixing, tap flush and secure the fixture. This enables fast, consistent results on-site. Developed primarily for domestic use, Bullfix is suitable for radiators, shelving, cabinets, TVs and other heavy wall-mounted items, delivering enhanced safety and long-term reliability.

Plus Series: clean, high performance fixing

The Plus Series woodscrews are designed for use across softwood, hardwood, MDF and chipboard, combining ease of use with strong fixing performance.

Key features include: ● CE approval to EN14592 ● Zinc plated, yellow passivated finish (3-5 microns) ● Reamed mid-section to reduce torque and prevent timber jacking ● Deep cut thread for improved pull-out performance ● Fully threaded up to 40 mm for secure clamping ● Type 17 cut point for fast, accurate insertion
