As we enter 2025, thoughts turn to forthcoming net zero targets, as ECA’s Jane Dawson says on pages 14-15: “There’s little doubt 2025 is a watershed for the transition to net zero. With just five years to go, decisions made this year will determine whether the UK will achieve clean power by 2030.” Jane looks at what’s in store for the electrotechnical industry this year, with thoughts on the recently published Clean Power 2030 Action Plan (see news on page 8), projects awaiting planning consent, and contractors’ new responsibilities related to low carbon tech.
We are delighted to be joined by Jane as our Guest Editor for this issue. After an introduction on page 6, you’ll notice Jane’s comments throughout the magazine, offering the ECA’s take on the direction of the industry as it evolves and adapts to meet increasing demand for electricity in a rapidly electrifying world.
Courtesy of CEF’s Darren Staniforth, this issue’s ‘Ask the expert’ provides an update on EICRs and the FI code, which has been “overused or misused in its current format” (pages 18-19), while a technical article from Modecsoft’s Spencer Henry explores the integration of additional earth conductors in parallel with the steel wire armour (SWA) of armoured cables (pages 30-33).
The pressing need for skilled workers to support the energy transition will be emphasised during this year’s National Apprenticeship Week, which takes place 10-16 February. In this issue, we hear apprentice turned Building Services Engineer Megan Whitbread’s apprenticeship success story (pages 20-23), and explore the much-needed growth of the electrotechnical workforce with JTL’s Chris Claydon (pages 24-25). Chris says “there is everything to play for in 2025 in apprenticeships and skills” and the year has certainly started on a positive note with new apprentice rates of pay coming into effect (see news on page 8) – here’s hoping we start to see the increase in apprentice numbers the industry so desperately needs.

Last year the UK produced more electricity from renewables than from fossil fuels. This milestone heralds a new era, one in which clean electricity is king. This is a bumper opportunity for growth in our industry. Yet, for the country to enjoy the safe and reliable electricity it has come to expect, there is a way to go. Our contributors in this issue outline what’s ahead in 2025.
The UK has made a commitment to deliver a net zero grid. But, as Stuart Dealing from ABB points out, to meet the increasing demand for electricity a comprehensive grid upgrade is vital (pages 28-29). Jen Tilbry from Schneider Electric describes how to reduce demand on the system by maximising energy efficiency and embracing sustainability (pages 34-35).
As electrification accelerates, Shaun Hurworth from Dimplex shines a spotlight on the investment and collaboration needed across the electrical supply chain (pages 40-41).
Core electrical skills are key as technology becomes increasingly complex. Manufacturers, distributors and competent installers must work together to achieve the energy efficiency and seamless operation consumers expect.
Collaboration is the buzz word in a rapidly electrifying world. The electrical industry is central to the net zero transition, but working with other trades – such as roofing, plumbing and digital – is also essential.
Diversity in our industry is sadly lacking, so it is heartening to hear from Troup Bywaters + Anders’ Megan Whitbread who is a role model for women embarking on an electrical career (pages 20-23). To solve complex problems requires a rich diversity of approach. The industry is at risk of losing its advantage unless it recruits a more diverse workforce.

The Government has unveiled the most ambitious reforms to the country’s energy system in a generation, to make Britain energy secure, protect households from energy price spikes, reindustrialise the country with thousands of skilled jobs, and tackle the climate crisis.
In a major milestone to deliver on the Prime Minister’s Plan for Change, which aims to drive economic growth and rebuild Britain with a mission-driven government, Energy Secretary, Ed Miliband, recently set out a detailed plan for achieving the target of clean power by 2030. The plan will provide the foundation for the UK to build an energy system that can bring down bills for households and businesses for good.
For too long, there has been no plan for building new energy infrastructure based
on an assessment of what the country actually needs for the long term. As a result, billions of pounds of clean energy projects have been held up by a clogged-up planning system and a dysfunctional power grid queue that means renewables projects cannot get online. The Government will now plan an energy system based on what the country needs.
The plan sets out bold measures to get more homegrown clean power to people, including cleaning up a dysfunctional grid system by prioritising the most important projects, speeding up decisions on planning permission by empowering planners to prioritise critical energy infrastructure, and expanding the renewable auction process to stop delays and get more projects connected.

To address the impact of recent national minimum wage changes on apprentice rates of pay, ECA, SELECT and Unite the Union have collaborated to implement new apprentice rates of pay, effective 6 January 2025. This measure aims to ensure fairness and stability for apprentices throughout their apprenticeships.
The electrical industry is facing a pressing need for skilled workers to support the low carbon transition, with an estimated requirement for 15,000 newly qualified electricians over the next five years. To meet this demand, the recruitment of at least 12,000 electrical apprentices annually is crucial, significantly higher than the current average of 8,000 per year. Ensuring fair pay is a critical element in attracting and retaining this talent pipeline.

The Heat Pump Association has welcomed the publication of the Electrification of Heat Demonstration (EoH) report, funded by the Department for Energy Security and Net Zero. This comprehensive study sought to explore the feasibility of a large-scale rollout of heat pumps across the UK, primarily focusing on evaluating their suitability for a wide range of homes and capturing customer feedback.
Key findings from the report indicate advancements in heat pump technology and performance since 2017. The EoH project monitored 742 heat pump systems installed across a range of dwelling types and ages, providing valuable insights into their effectiveness in different environments.
Notably, the median seasonal performance factor (SPF) for air source heat pumps (ASHPs) surpassed previous benchmarks –improving by more than 10% compared to previous installations – highlighting improvements in efficiency compared to 2017 levels. Additionally, compared to a typical fossil fuel heating system efficiency of 84%, the report highlights an average of 293% efficiency for the sampled ASHPs.

The UK automotive and charging industries have been invited to shape the UK’s transition to zero emission vehicles (ZEVs), as the Government works with the sector to harness the huge opportunities for economic growth and improve living standards for working people.
Transport Secretary, Heidi Alexander, launched the consultation – which closes on 18 February – to seek views from industry on how to deliver on the manifesto commitment to restore the 2030 phase-out date for new purely petrol and diesel cars and make the transition to ZEVs a success.

Organisations and investors spearheading the rollout of EV charging infrastructure across the UK have issued a coordinated call on the Government to urgently recommit to existing EV sales targets.
The joint warning from BEAMA, ChargeUK, REA and UKSIF urges the Government not to cave to short-sighted demands to water down the commitment for vehicle manufacturers to sell a minimum of
22% zero emission vehicles (ZEVs) in 2024, rising to 80% in 2030 and 100% in 2035. A swift, decisive and public confirmation by government that EV sales targets will remain unchanged is needed for private investors to fund rapid rollout of charging infrastructure, and to reassure consumers that their next vehicle should be zero emission.
Yselkla Farmer, CEO of BEAMA, said, “We cannot underestimate the impact
The latest quarterly Building Engineering Business Survey reveals that close to two thirds (63%) of electrotechnical and engineering services businesses are worried about delays to projects and the impact this can have on cashflow.
The survey, conducted by ECA in partnership with BESA, SELECT and SNIPEF, and sponsored by Scolmore, also showed that almost a quarter (23%) of respondents expected their business’ performance to have worsened by the end of 2024 – a figure which has risen by 7% since the last survey in August 2024.
The survey suggests optimism about the number of direct employees in the sector, with 16% predicting this will go up in 2025. However, the same proportion of respondents felt the numbers of apprentices would fall in 2025. The number of respondents reporting vacancies in their businesses rose by 10% to nearly two in five respondents (36%).

moving the goal posts again could have on UK investment and pace of electrification. We recently published our plans for a UK Industrial Strategy, which makes a strong case for the growth opportunities stemming from this sector. A decision to back track on the ZEV mandate will be entirely counter to the UK’s longer-term ambition to drive inward investment for manufacturing.”

ECA recently joined others in the energy industry, including Energy UK, the Thermal Storage Association and Electrify Industry, in signing a joint letter to Bill Esterson MP, Chair of the Select Committee on Energy Security and Net Zero (ESNZ). The letter urged the committee to set up an urgent inquiry to explore the opportunities and barriers to electrifying industry.
The clerk to the ESNZ Select Committee responded positively, while promising no guarantees, indicating the committee would consider the request early in 2025. He indicated that the information provided by industry would be used as the basis of conversations with Ofgem, National Energy System Operator and the Secretary of State.

Arecent look at the UK building energy management systems (BEMS) market performance in Q3 2024 revealed a promising 3.2% year-on-year increase, up to £854 million. This emphasises the growing demand for smart buildings and acknowledgement of the importance of reducing energy consumption through BEMS.
While the construction industry as a whole is combating significant challenges, including a major skills shortage, the building controls sector continues to perform admirably, with major companies and organisations leading the way when it comes to innovation and the utilisation of technology to improve energy efficiency and
reduce carbon emissions in the built environment.
BCIA President, Stacey Lucas, said, “The wider construction industry has faced some significant challenges in the last few months, but the building controls sector has continued to perform commendably. This is in no small part down to the increasing focus on sustainability throughout the built environment and the drive to reduce carbon emissions wherever possible.
“The BEMS industry remains a vital linchpin of energy efficiency and that’s set to increase further as we move into 2025 and beyond.”

Recolight has welcomed the publication of the new code of practice for the remanufacture of lighting equipment, published by BSI and numbered BS 8887:221 2024.
The document provides a structured approach to the assessment of used luminaires and components, defining a scope of works, electrical and mechanical remanufacture,
component selection, markings and instructions, and testing/validation.
Remanufacture is a vital way in which producers and end users can better embrace a circular economy, by keeping products (or parts of products) in service for longer. Typical embodied carbon savings from remanufactured products are 5080% compared to new products, with
similar levels of waste avoidance.
An increasing number of UK lighting companies are now engaging in remanufacture. One of the most common approaches is to retrofit fluorescent luminaires with LED light sources, thus retaining the body of the luminaire.

There’s little doubt 2025 is a watershed for the transition to net zero. With just five years to go, decisions made this year will determine whether the UK will achieve clean power by 2030. The publication of the Department for Energy Security and Net Zero’s Clean Power 2030 Action Plan at the tail

end of last year sets out the priorities for government.
There is good news. If you have a project waiting for planning consent and grid connection that will be delivered before 2030, it is likely you will now jump to the head of the queue. ECA has been advocating to alleviate these bottlenecks since 2022. We are also expecting to see an uplift in activity relating to the Warm Homes Plan, which includes the Boiler Upgrade Scheme for heat pump installation. Something else to look out for is a final decision on the delayed Review of Electricity Market Arrangements.
While it is good to see movement on a number of regulatory issues, there

is much that is not included in the Action Plan. The price of electricity remains stubbornly high, and there is no sign a review of electricity taxation is close, despite work by ECA and others. Unfortunately, safety remains the province of other government departments – this is a matter of concern, given the speed of change in our industry.
The importance of safety and technical competence
Low carbon technology brings new legislation, standards, and equipment, and it’s fair to say that many
“With the speed of change, a major concern is the potential for uncontrolled work carried out by unqualified contractors.”
installers are unfamiliar with their new responsibilities. Contractors are now expected to verify that low carbon technologies meet requirements, as well as designing and installing new systems. In addition, they must ensure safe operation and maintenance.
One of the most obvious errors is a failure to carry out an assessment of existing systems. This is true for both electrical capacity and structural loading – a mistake which can be avoided by employing a ‘competent person’, as designated in the Building Safety Act.
With the speed of change, a major concern is the potential for uncontrolled work carried out by unqualified contractors. Safety and technical competence are vital; a lack of training can cause a threat to life, as well as property. As electrification accelerates, this danger must be at the front and centre of new policy and regulation.
This coming year ECA is shining a spotlight on the safe transition to net zero.
A digital series, ‘Electrifying our Future’, aimed at policy makers will emphasise the paramount importance of safety. It will explore related advancements in skills development, professional competence, business resilience, and policy and regulation to keep up with the pace of change necessary.
The series launches in the House of Lords at the end of February.

Issue 7 of Best Practice Guide 4: Electrical Installation Condition
Reporting introduces a new approach to the use of the Further Investigation (FI) code. What does the change mean for Electrical Installation Condition Reports (EICRs)?
Need some technical advice?
Darren is here to help! Send your questions to: info@electrotechnicalnews.com
Outside of JPEL/64, the Wiring Regulations committee, industry bodies regularly come together to discuss guidance for the electrical industry on various topics. The outcomes of these discussions are published by Electrical Safety First (ESF) as best practice guides. These free PDFs are available via the ESF website and some scheme providers’ websites and portals.
Recently, Best Practice Guide 4: Electrical Installation Condition
Reporting was reviewed and updated, with Issue 7 now available. This guide exists to clarify the correct use of classification codes (C1, C2, C3, FI) during the periodic inspection and testing of electrical installations, considering the requirements of BS 7671. While primarily focused on domestic and similar installations, the guidance can also apply to other types of installations in comparable situations.
7 changes
The new Issue 7 document marks a notable change in approach regarding the use of the FI code. In the past, examples of when the FI code should be applied were provided. However, the current version includes minimal reference to FI, reflecting a consensus across the industry that the FI code has been overused or misused. In many cases, observations
were identified, but the FI code was incorrectly attributed.
This change aligns with proposed amendments to BS 7671. A proposal published by BSI towards the end of last year suggests modifying the definition of ‘Further Investigation’. Currently, FI is defined as ‘further investigation required without delay’. The proposed revision would change this to ‘further investigation recommended’.
Additionally, FI presently results in an ‘Unsatisfactory’ outcome on the EICR. If the proposed changes are adopted, FIs would be grouped
with C3 observations, potentially allowing for a ‘Satisfactory’ outcome, depending on other factors affecting the inspection.
These changes have raised concerns among electrical designers, inspectors and contractors across the UK. Many fear that the revised approach could hinder their ability to complete EICRs effectively, potentially leaving parts of an installation uninspected and dangerous items unidentified. Some argue that the current definition of FI in BS 7671 provides necessary protection, allowing them to highlight
“If the proposed changes are adopted, FIs would be grouped with C3 observations, potentially allowing for a ‘Satisfactory’ outcome.”
areas requiring further attention to clients.
Through discussions with IET engineers during recent CEF TechTalks, it became evident that in many cases, other classification codes should have been used. Inspectors should also utilise the ‘operational limitations’ section to note when an inspection is incomplete due to time constraints or physical barriers, rather than relying on the FI code as a fallback.
Examples presented to industry bodies clearly demonstrate that the FI code has been overused or misused in its current format. While the proposed changes represent a significant shift, they are necessary for ensuring the accurate application of classification codes. However, successful adoption will require extensive education and clear communication across the industry.
By addressing these issues and embracing the changes, the industry can ensure that EICRs continue to be effective tools for safeguarding electrical installations while maintaining professional standards.
Meet Megan
Megan Whitbread is a Senior Electrical Building Services Engineer at Troup Bywaters + Anders in London. After completing an advanced apprenticeship and a degree apprenticeship in Building Services, Megan recently completed her MSc in Smart Energy and the Built Environment at UCL.
In 2014, as she neared the end of grammar school, Megan had considered her options for further education, eventually settling on a local sixth form – due in part to it being the only real pathway presented to her. “At my school, the expectation was to go to sixth form and then university,” she explains. “Apprenticeships weren’t really discussed – and when they were mentioned, they were seen as the ‘lesser’ option compared to going to university.”
However, Megan quickly found her AS Levels challenging. Despite strong coursework and a passion for learning, she struggled with exams and no longer felt suited to the school environment. So, she started exploring other options and, with the help and support of her parents, found her apprenticeship. “During
Ten years ago, Megan Whitbread turned her back on her sixth form studies to embark on an apprenticeship. Now a Senior Electrical Building Services Engineer at Troup Bywaters + Anders in London, Megan frequently speaks at industry events sharing her apprenticeship journey and encouraging and inspiring others to consider a career in engineering. Electrotechnical News caught up with Megan to hear her inspiring story.
sixth form, I realised I love to learn but the traditional school route wasn’t for me. My parents actually made me aware of apprenticeships as an option. Through research, I discovered building services engineering and it immediately sparked my interest. Hands-on experience whilst studying at the same time just made more sense to me.”
She left sixth form part way through and started as a Level 3 apprentice at Troup Bywaters + Anders at the age of 17, earning her BTEC Level 3 in Building Services Engineering and NVQ. “I remember a couple of people at school joking that I was a ‘drop out’ for not finishing sixth form, but it didn’t bother me at all!” Megan then embarked on a Level 6 degree apprenticeship at London South Bank University, earning a First Class Honours in her Bachelor of Engineering and getting her IEng status from CIBSE. This set her up to enrol at UCL for an MSc in Smart Energy and the Built Environment, which she’ll be graduating from this May.
Reflecting on the start of her apprenticeship journey, Megan says, “The thing that worried me the most was starting my first real job! Going straight from school into a professional office environment felt nerve-racking at first, but everyone was so friendly that those nerves quickly went away.” In the years that followed, Megan’s career went from strength to strength. In 2019,

Megan was a face of the Government’s multi-million pound ‘Fire It Up’ campaign
she was featured in the Government’s multi-million pound ‘Fire It Up’ campaign designed to boost apprenticeship numbers. In 2020, she was crowned Apprentice of the Year at the CIBSE Young Engineer Awards. The only regret she has about her apprenticeship is that she didn’t start it sooner. “I wish someone had told me how valuable apprenticeships really are in terms of hands-on experience and career progression. At the time, I didn’t fully realise how much I’d learn on the job and how quickly I’d gain skills that would set me apart in the industry.
“I think it’s so important for those considering an apprenticeship to understand that they aren’t just about starting a job; they’re about opening doors to long-term career opportunities, building connections, and constantly growing. If I’d known how much they could shape my career in such a positive way, I would have jumped in even sooner!”
In the decade since Megan started her apprenticeship, she has
“Talk about the tech, the future of energy, and the impact new apprentices will have. Show young people how they can be part of something huge and meaningful.”
witnessed a shift in the perception of apprenticeships, with the conversation changing from ‘Why would you do an apprenticeship?’ to ‘Why wouldn’t you?’. “Back in 2015, apprenticeships didn’t get nearly as much recognition as they do now,” she says. “They were often seen as a ‘fallback’ option, especially compared to university, and there was this stereotype that they were
only for manual trades. Over the years, though, I’ve seen a real shift. Now, apprenticeships are much more respected, and people are starting to see them as a smart, practical choice, not just for trades but for industries like tech, engineering, finance, and even law. The introduction of degree apprenticeships has helped too, because they show you can work, earn, and still get top-level qualifications without the debt.
“There’s also been more promotion of apprenticeships in schools and the media, so young people actually know they exist and what they offer. That awareness just wasn’t there as much 10 years ago.”
Indeed, according to figures, growing numbers of school leavers are considering apprenticeships. Last year, UCAS said that whilst ‘university has been the top choice for students all over the UK for longer than we can remember, apprenticeships are becoming increasingly popular and in demand with employers’. Megan believes more school leavers are picking apprenticeships because they’re starting to see the perks: “You can earn while you learn, skip the student debt, and get straight into hands-on work. Employers love the practical experience, and with clear career paths and more industries offering apprenticeships, it’s becoming a no-brainer for a lot of young people, especially with all the financial pressures out there.”
For her, Megan says the greatest benefits have been “getting a BEng and MSc without any student debt, and graduating with my BEng plus seven years of work experience already under my belt”. And the biggest challenge? “Balancing studying with a full-time job. Apprenticeships are often seen as the ‘easy’ option, but managing both is definitely a skill you need to master.”
Despite the progress made, Megan says apprenticeships still don’t get the same airtime as university routes, and a stigma remains in some circles where they’re seen as ‘second best’ to university. “Not all schools push apprenticeships as an option, focusing instead on academic routes. Schools need to do more to showcase
them as an equal – if not better –option for some careers. Some people also worry about low starting pay or not knowing what career progression looks like. Additionally, there aren’t always enough opportunities in every region or industry, which makes access tricky.”
However, she adds, “I have seen a lot of companies stepping up and showing young people what apprenticeships offer, beyond just a job: real skills, real pay, and real progression.” To the rapidly expanding electrotechnical industry, this message is key. As the transition to net zero creates a surge in demand for qualified electricians and electrical engineers, Megan emphasises the importance of continuing to champion apprenticeships. “The industry needs to shout about this opportunity, working with schools and colleges to explain how careers in engineering tie into big, exciting things like green energy and net zero goals. Offering more apprenticeships with competitive pay and clear pathways to qualifications is key. And make it exciting, talk about the tech, the future of energy, and the impact new apprentices will have. Show young people how they can be part of something huge and meaningful.”
Megan is rightly proud to be part of something meaningful herself. Now a Senior Electrical Building Services Engineer at Troup Bywaters + Anders, she leads the electrical engineering designs for major healthcare facilities
As the Honorary Secretary of the CIBSE Young Engineers Network (YEN) London, Megan is keen to encourage young people to get involved with a community that’s supporting and developing the next generation of engineers.
“I joined CIBSE YEN in 2022 because I wanted to connect with other young professionals in the building services industry and expand my network. The group offers a great platform to ask questions, share ideas, learn from others, and take part in activities that push the industry forwards. It’s a chance to learn beyond the day-to-day job, stay up to date with industry trends, and get involved in projects and events that help shape the future of the sector. Being part of such a network can really boost career growth and personal development.”
across the UK. “The most rewarding part is knowing my work supports healthcare environments that make
Jane Dawson, ECA’s Head of External Affairs
“Attracting more women into electrical apprenticeships is vital to the net zero transition. Low carbon tech involves integration with existing systems and cooperation between trades. Integration and collaboration require a diverse range of skills; problem solving and communication are key. If we are only recruiting from a pool of half the population our industry will stagnate. While girls can see the benefits in starting a trade apprenticeship, their parents and teachers may point them in other directions. To recruit a new generation of electrical apprentices we must persuade parents and schools of the vast opportunities for securing a well-paid job in an expanding industry.”
a real difference in people’s lives,” she says. “Designing reliable, energyefficient systems for hospitals means ensuring patient safety and improving staff efficiency. I love the challenge of creating innovative solutions for each unique project, and it’s fulfilling to know my designs contribute to better healthcare facilities across the UK.”
As for her advice to anyone considering an apprenticeship and a career in engineering: “Go for it! Engineering is one of those fields where hands-on experience is gold, and an apprenticeship lets you dive right in. Don’t be afraid to ask questions, learn from your mentors, and push yourself. And remember, the skills you gain are in demand everywhere – you’re setting yourself up for a career that can take you anywhere in the world.”
There is everything to play for in 2025 in apprenticeships and skills, says Chris Claydon, Chief Executive, JTL Labour’s Industrial Strategy and education reforms highlight the role of skills in achieving its missions to drive economic growth and improve workforce productivity.

This means we’re out-performing most other training providers in the sector, training a third of the electrical workforce.
Over the last three years the sector has trained an additional 1,000 apprentices per year, compared with the previous three years. Yet, collectively we are only scratching the surface of what is needed. In 2025, JTL will train almost 2,000 electrical apprentices out of a total of 7,500 starts in England. However, the ECA estimates that 10,000 annual starts are required to sustain the current qualified electrician workforce. That is before you factor in the scale of the projects the Industrial Strategy looks to bring forward.
There is clear demand for more apprenticeships from both learners and employers; the bottleneck is training capacity. Finding sufficient qualified tutors and assessors is challenging, an issue compounded by a significant funding deficit.
A workforce fit for the future
Employers urgently need qualified electricians to fit new homes, install systems at Hinkley Point C and HS2,
“Skilled tradespeople cannot be part-trained, cut corners or compromise in their qualification.”
and power new data centres. These are the same skills already in demand for retrofitting existing homes and expanding our EV charging network. We also risk underestimating the cross-sectoral nature of electrical work. Electricians are employed across arts and entertainment sectors, for example, as well as construction services.
Further still, the workforce must be nimble. New technologies are evolving rapidly, representing great opportunity for electricians to be at the forefront of innovation with well paid, rewarding work across different sectors.
It is therefore crucial that their training has a solid foundation in principles of safety and occupational competence. Skilled tradespeople cannot be part-trained, cut corners or compromise in their qualification. The consequences would be disastrous. JTL apprentices undertake rigorous
training to develop the skills and knowledge to deliver safe, energyefficient homes and buildings fit for the future. The complexity of the course reflects the high standards required for these jobs.
Policy and funding challenges
In the rush to meet homebuilding and
infrastructure targets it’s imperative that neither the Government nor providers take short cuts. So-called short courses claiming to result in fully-qualified electricians are a recipe for disaster, and the use of non-qualified or under-qualified personnel would undermine every effort to meet demand.
Apprenticeships are the industry recognised pathway for new entrants and occupational competence. It is that competence which is so key in this safety-critical industry.
The rhetoric from central government, and increasingly regional government, does recognise the urgent need to bring new and fully qualified talent to the sector. But it does not fully fund training provision nor give us the resources we need. We are expected to do more with less.
Despite the policy and funding challenges we face, JTL is agile and resilient and will step up to play our role in the much-needed growth of the electrotechnical sector. Apprenticeships are not just a solution to today’s skills shortages; they are a pathway to a prosperous future.

Phil
Brown, Director of Product & Marketing at NVC Lighting,
answers some key questions about the installation and maintenance of emergency lighting.
Phil Brown Director of Product & Marketing at NVC Lighting
Q1. What is the purpose of emergency lighting in commercial buildings?
Emergency lighting ensures safety during power outages or emergencies by illuminating critical areas and guiding occupants to exits. It’s an integral part of any building’s safety system, designed to function automatically when the main power supply fails.
Q2. How is emergency lighting powered?
Emergency lighting, whether selfcontained or centrally supplied, is battery powered. The battery in turn is fed by a permanent live supply. This ensures it activates automatically if the main electricity is cut, remaining functional even when other lighting systems are off. Backup power often comes from integrated battery systems or central power sources.
Q3. What standards should emergency lighting adhere to?
In the UK, BS 5266 serves as the primary code of practice for emergency lighting. While intended as a guide only, compliance with BS 5266 ensures alignment with fire and
“BS 5266 serves as the primary code of practice for emergency lighting.”
safety regulations. It covers system design, installation, maintenance and testing, providing a framework for reliable performance during emergencies.
Q4. Who is responsible for maintaining emergency lighting? Ongoing maintenance typically falls to the building owner or manager.
However, contractors must provide clear documentation during system handover. Maintenance involves either self-test systems, which automatically detect faults, or manual testing, requiring personnel to conduct regular checks. Monthly switch tests and annual duration tests are key to ensuring functionality.
Q5. What are the environmental considerations for emergency lighting systems?
Modern systems often use LiFePO4 (lithium iron phosphate) batteries, which are longer-lasting, more efficient and more robust than traditional lead-acid batteries. These sustainable options reduce environmental impact and offer costeffective solutions.
Q6. What components are essential for an effective system?
An emergency lighting setup includes:
• Emergency luminaires (maintained or non-maintained configurations).
• Illuminated exit signs to guide safe evacuation.
• Test systems (manual or selftesting) to ensure functionality.
• Control systems for centralised monitoring and fault reporting.
Q7. What role does documentation play in maintenance?
Accurate records of testing, updates and repairs are vital for compliance and risk management. The ‘golden thread’ approach, emphasising traceable safety information, is becoming increasingly critical in construction practices.
Final note
Emergency lighting systems are about reliability, not aesthetics. Contractors play a crucial role in ensuring these systems perform as intended, safeguarding lives and property during critical moments.

If we are to reach net zero carbon emissions, we need to transition to renewable energy. But the age-old question levelled at renewable energy is that of power continuity. With the advent of AI, data centres need more and more power and, critically, it has to be uninterruptible. Is net zero even possible with these demands, and can it be reached safely? Stuart Dealing, Sales, Service and Project Execution Leader at ABB Power Protection, says yes…
Stuart Dealing Sales, Service and Project Execution Leader at ABB Power Protection
The world is on a mission to replace our main and most reliable sources of energy for more sustainable, though inherently intermittent, alternatives. Simultaneously, our
demand for energy is growing at a near exponential rate.
The average consumer does not realise the energy cost of sending and receiving emails and hosting a website. But, as our lives become more interconnected, our need for power skyrockets. With the advent of AI, which comes with extreme energy costs, data centres are suddenly an enormous burden on the National Grid.
In response to this burden, the grid is undergoing a massive and
comprehensive upgrade, which will be critical in meeting demand while allowing us to transition to net zero safely. But it will take time, and even when the upgrade is completed, there will still be peaks and troughs in power supply as well as the occasional outage.
These peaks, troughs and outages all have to be planned for and mitigated if the transition to net zero is going to be a success. There are many processes in our modern lives where, if we were to lose power, the impact
“These peaks, troughs and outages all have to be planned for and mitigated if the transition to net zero is going to be a success.”
would be devastating. Data centres themselves are critical to our day-today lives – more than just emails and AI, they power our banking systems and store our healthcare data, and they require uninterrupted power.
Bridging the power gap
Fortunately, we know first-hand that there is a solution to bridge this power gap while the grid undergoes an update and the world transitions to renewables, and it’s the forwardlooking data centres that are deploying high power uninterruptible power supply (UPS) systems to bridge the power gap from the utility companies.
Jane Dawson, ECA’s Head of External Affairs
“Electrification promises long term reduced energy costs, as well as energy security and huge opportunities for electrical business. But certainty, continuity, and consistency are key to gaining the confidence of business and consumers. Central to the safe transition to net zero is competent installation, carried out by qualified electricians. The safe and reliable electricity we all enjoy today relies on collaboration between the grid, manufacturers and installers.”
A UPS constantly monitors the flow of energy received from the grid to a data centre. When there is a voltage dip, surge or outage, the UPS detects this, and automatically provides the expected voltage to the load either through its converters or by utilising an energy storage system such as a battery.
In this way, a UPS delivers clean, continuous power to data centres around the world which protect them from power quality events. ABB’s UPS systems have a modular architecture and operate at high levels of efficiency, meaning lower power energy costs and, more
critically, greater sustainability.
Successful transition
With this technology, a full-scale grid upgrade and a wholesale transition to renewables is possible, without threatening the services we rely on. So yes, even with skyrocketing demands for power, we can transition to net zero safely.

Spencer Henry Modecsoft
The integration of additional earth conductors in parallel with the steel wire armour (SWA) of armoured cables is a topic of considerable importance within electrical installation practices. This configuration aims to enhance fault current pathways and ensure compliance with electrical safety standards. PD CLC/ TR 50480:2011 provides a technical framework for such scenarios, further tailored in the UK through the National Annex (NA).
This article examines the considerations, benefits and practical implications of running additional earth conductors separately yet in parallel with the steel armour of SWA
cables, drawing on the guidance of PD CLC/TR 50480:2011 and the UK National Annex.
PD CLC/TR 50480:2011 addresses the principles of fault current paths, impedance management and protective measures. It highlights the importance of low-impedance fault current paths to ensure effective disconnection of protective devices during faults.
The UK National Annex perspective The UK National Annex refines the principles of PD CLC/TR 50480:2011 to align with BS 7671 and regional practices. The Annex acknowledges the practicalities of using SWA as an earthing path while outlining scenarios where supplementary earth conductors are beneficial or necessary, such as:
• High fault current scenarios where the steel armour alone cannot provide sufficient fault current capacity.
• Long cable runs where impedance in the armour could impede effective fault clearance.
• Specific installations requiring redundancy or enhanced reliability in fault current pathways.
In this technical article, Modecsoft’s Spencer Henry explores PD CLC/TR 50480:2011 and the UK National Annex NA: Additional Earth Conductors and Steel Armour in Parallel.
“No matter how many conductors are placed in parallel, the overall impedance calculated from the resistive and reactive elements of the cable can never be below a fixed value.”
Additional separate earth conductors
Often designers believe running additional earth conductors in parallel with SWA steel armour will offer two key advantages, which are:
1. Enhanced fault current capacity: The steel armour in SWA cables provides a fault current path, but its impedance may be too high in certain installations. Adding a parallel earth conductor reduces overall impedance, facilitating faster and more reliable disconnection of protective devices.
2. Reduced impedance for extended runs: Over long distances, the impedance of the steel armour increases, reducing its effectiveness as a fault current path. Running an additional lowimpedance earth conductor in parallel mitigates this issue.
NEW Solar PV Test Kits from Di-LOG represents a significant leap forward in Photovoltaic (PV) testing technology. Designed for professionals in the renewable sector, the PV Kits offer enhanced testing capability to 1000V DC and the ability to measure cell temperature in accordance with IEC 62446-1.
Mathematically for considering the fault currents this is expressed as equation 1:
Where:
Rs and Xs = the resistance and reactance of the upstream system supplying the circuit
R1 = line conductor resistance
RP = protective conductor resistance
X1 = line conductor reactance
XP = protective conductor reactance
Uo = nominal voltage (phase to earth)
If = earth fault current
Unfortunately, UK National Annex of PD CLC/TR 50480:2011 can in fact negate both of those advantages.
As the steel wire is magnetic, UK National Annex of PD CLC/TR 50480:2011 requires a coefficient value to account for this be applied to the resistive parts of steel conductors used for CPCs.
The calculation of the resistive parts of equation 1 is adjusted by:
When calculating cable impedances, the UK National Annex of PD CLC/TR 50480:2011 requires a fixed reactive value be used in the calculations.
The calculation of the reactive parts of equation 1 is adjusted by:
Where:
Rc = resistance of the line conductor
Ra = DC resistance of the armour adjusted to the appropriate operating temperature
Rcpc = resistance of the external separate CPC
L = length of conductor
On conductors 95mm2 and below where the resistive element of the cable is higher than this value, this often is not an issue. Where, however, the cable is over 95mm2 or is run over very long distances, the reactive value required in the calculation has a negative effect on the design.
No matter how many conductors are placed in parallel, the overall impedance calculated from the resistive and reactive elements of the cable can never be below a fixed value. This is because the reactive will be higher than the parallel sum of the resistive parts. This has a knock-on effect for the calculated
earth fault loop impedance, causing higher than expected values. Effectively placing a greatly shortened limit on the distance, a steel wire armour with a separate earthing conductor can be run.
Often the only solution to this is to increase the size of the steel wire armour itself, meaning increasing the overall size of all the armoured cable phase conductors.
Adiabatic checks
In most cases, when we parallel a number of conductors together, we sum CSA, parallel earth conductors are treated as a single fault path for adiabatic checks. This to prove that the overall CSA is adequate to carry the fault current that could potentially pass through it.
However, in UK National Annex of PD CLC/TR 50480:2011 it does not stop there. The document gives specific calculations to divide how much fault current is expected to pass through the steel wire armour and the separate earthing conductor respectively.
To calculate:
Fault current carried by the armour (Ia):
“The document gives specific calculations to divide how much fault current is expected to pass through the steel wire armour and the separate earthing conductor respectively.”
Fault current carried by the separate earthing conductor (Icpc):
Note: The sum of the calculated currents from these equations individually will not equal the sum of If as may be expected. This is because no account of the relative phase angles in the calculation is considered.
Selectivity
Spencer’s ECA webinar covers applications of this practice, including case studies and practical examples
The adiabatic checks need to be done for both the steel wire armour and the separate earthing conductor independently to ensure the proportion of fault current carried individually in the two different materials can be withstood.
One recommendation within PD CLC/ TR 50480:2011 is that the separate earthing conductor CSA should not
be less than a quarter of the line conductor. This may however not always be feasible, such as where multiple large phase conductors in parallel are used or due to limited space in cable ducts or other containment systems.
Webinar insights
In my webinar with the ECA (accessible at www.youtube.com/ watch?v=UaIdvZjHfzg), we explored applications of this practice, including case studies and practical examples.
The discussion emphasised how UK National Annex of PD CLC/TR 50480:2011 affects design practices and how to ensure compliance and functionality when designing using additional separate earthing conductors and steel armour in parallel. This is showcased in Modecsoft’s ElectricalOM software functionality developed specifically to address this issue.

An overhaul was recently ordered of certain employee safety systems at the University Hospitals of North Midlands NHS Trust, with improvements to lone worker security and safety identified as a priority. Layer One Installations found the perfect match in Vista’s video surveillance products and the FT-45 Feed-Thru Modular Plugs and Crimp Tool from IDEAL Electrical to deliver a high quality, reliable and compliant solution.
The University Hospitals of North Midlands NHS Trust (UHNM) has two sites: Royal Stoke University Hospital, located in Stoke-onTrent; and County Hospital, located in Stafford. It is also home to Staffordshire Children’s Hospital at Royal Stoke. From these hospitals, the Trust provides a full range of general acute hospital services for approximately 1.1 million people living in and around Staffordshire, as well as specialised services for three
million people across a wider area, including neighbouring counties and North Wales. UHNM is one of the largest acute trusts nationally with over 11,000 staff.
Following a thorough review of working practices in 2021, the IT department identified concerns about lone worker employee safety, regulatory compliance and operational efficiency in the central core IT rooms containing servers (cold aisle containment storage
facilities). In the event a lone worker entered a cold aisle containment unit, and there was an emergency or the worker failed to follow protocol, they could potentially go undiscovered for 12-14 hours until someone else started their shift or the area happened to be entered.
Video surveillance equipment to the rescue
The Trust was keen to ensure a safer environment for any employees working alone in potentially
hazardous situations or remote locations, whilst also mitigating the risks associated with lone working – such as accidents, injuries and security incidents – and complying with regulations and standards regarding lone worker safety. At the same time, the Trust hoped to increase efficiency and productivity by encouraging lone workers to adhere to safety protocols.
The Trust called upon its existing contractor, Layer One Installations, to assess the IT department’s security requirements. Headquartered in Manchester with a nationwide operation, Layer One Installations offers a wide range of services including structured cabling, fibre optics, CCTV systems, Wi-Fi surveys, uninterruptible power supplies and intelligent security systems.
FT-45 open and closed
“With a clear connector design, the conductor order can be checked and adjustments easily made if needed.”
Following the assessment, the decision was made to install a CCTV system designed to improve lone worker operating conditions in the central core IT rooms containing critical servers and IT equipment across five hospital sites, with the Trust keen to use an NDAA compliant solution.
Marc Jones, Layer One Installations’ director, turned to Norbain Security Distribution to assist him in identifying the products needed to fulfil the Trust’s requirements, with the Vista VIP Series of NDAA compliant fixed Dome cameras selected as the best fit across the five locations.
Given the nature of the project, it was vital the job was completed quickly, without causing disruption to the hospitals and avoiding any costly delays. So, to enable fast and accurate installation of the CCTV equipment, Marc opted for a tried and tested favourite of Layer One Installations –the FT-45 Feed-Thru Modular Plugs and Crimp Tool from IDEAL Electrical.
Used on data installations around the world, the FT-45 allows installers to speed up and simplify the termination of RJ45 plugs by eliminating the need to trim conductors to length first.
The Modular Plugs feature open ends, enabling installers to feed the conductors completely through the connector before crimping. With a clear connector design, the conductor order can be checked and
adjustments easily made if needed. The Crimp Tool is then used to trim and crimp the cable in one simple step.
With five installation sites to complete, the ability to execute CAT5e, CAT6 and CAT6a cable terminations correctly the first time was key to the smooth and speedy running of the project.
A job well done
Layer One Installations prides itself on high standards of installation, and the UHNM project delivered just that, thanks to the pre-existing relationship between the contractor and the Trust, as well as Layer One Installations’ prior knowledge and experience of both the Vista range and the IDEAL Electrical FT-45 FeedThru system.
Marc says, “The project was a success. We evaluated the client’s
If you’re installing a wired network connection for a heat pump installation, the FT-45 Feed-Thru Crimp Tool from IDEAL Electrical is the perfect solution when preparing your network cables.

requirements and proposed innovative solutions that would be straightforward to work with. We knew from previous experience that we could rely on Vista and IDEAL Electrical to provide cost-effective, quality solutions that would reliably do the job, without mistakes or delays.
“We’ve been using IDEAL products for years, so when I knew the project
required multiple terminations across numerous sites, the use of the Modular Plugs and Crimp Tool was a no-brainer. A faster, more accurate install was achieved, with the new CCTV system up and running in no time.”
Through the implementation of the new video surveillance solution, the Trust’s IT department has been able to meet their objectives. The
CCTV system has enabled real-time monitoring of lone workers, allowing for a quick response in emergencies or accidents, with the IT department now able to proactively identify and address potential safety hazards much more effectively.

The United Kingdom stands at a pivotal juncture in its pursuit of net zero emissions, with electrification and clean heating at the forefront of this transition. BEAMA is the UK trade association for manufacturers and providers of energy infrastructure technologies and systems, representing more than 200 companies. Their recent #AcceleratingElectrification campaign underscores the urgency and economic potential of this shift and it’s vital we highlight the critical role of accelerating electrification in achieving our environmental and economic objectives.
Electrification is not merely a component of decarbonisation; it is the linchpin. Transitioning from fossil fuels to electricity – especially when sourced from renewables – addresses the pressing need to reduce greenhouse gas emissions. This shift is particularly vital in the heating sector, which accounts for a significant portion of the UK’s energy consumption and carbon footprint. Electric heating solutions, such as heat pumps and advanced electric radiators, offer efficient and

“Electric heating solutions, such as heat pumps and advanced electric radiators, offer efficient and sustainable alternatives to traditional heating methods.”
sustainable alternatives to traditional heating methods.
Beyond environmental benefits, accelerating electrification presents substantial economic advantages. Investing in the electrical products supply chain can transform the UK into the ‘low carbon workshop of the world’, fostering job opportunities and economic growth.
Despite the clear benefits, the UK’s progress towards electrification faces significant hurdles. Policy delays and reversals have eroded investor confidence and hindered the deployment of essential technologies.
The need for clear and consistent policies
To bridge the gap between ambitious targets and actual deployment, decisive action is imperative. This includes providing clear policy direction, establishing detailed roadmaps, and offering incentives that stimulate investment in the electrification supply chain. As BEAMA’s Strategy Director, Kelly Butler, aptly states, “The UK is clearly back in the global race for net zero delivery, and with a series of imminent policies that will accelerate electrification across power, heating and transport there are reasons for optimism.
“In delivering this complex change we must always mind that the customer is at the centre, and they must have choice. We must also consider the gap which continues to grow between the projected energy sector investment needed to meet our targets and the current rate of deployment.”
At Dimplex we are unwavering in our commitment to advancing electrification and creating clean heating solutions. Our innovative products are designed to meet the evolving needs of consumers and contribute to the UK’s decarbonisation goals. However, the success of these initiatives relies on a supportive policy environment that encourages widespread adoption and investment.
Accelerating electrification is not just an environmental imperative but a significant economic opportunity. By
Jane Dawson, ECA’s Head of External Affairs
“Electrification is the fastest, cheapest, and most efficient way for the UK to reach its net zero goals. To reach these targets safely, collaboration across the electrical supply chain has never been more important.

Inspection and testing of electrical installations is an important and necessary activity to protect the safety of the users of the installation against fire, shock and burns and damage to property, as set out in BS 7671 Chapter 13: Fundamental Principles. Here, Kewtech provides an in-depth look at inspection and testing safety.
In Chapter 64 of the Wiring Regulations, Regulation 641.1 requires new installations and alterations and additions to existing installations to be inspected and tested during erection and on completion to verify, so far as reasonably practicable, that the requirements of BS 7671 have been met.
For a new installation, or an addition or alteration to an existing installation, three activities are to be undertaken in sequence. They are to inspect the installation, which shall normally be done with the installation disconnected from the supply, to carry out the tests in the appropriate sequence defined in Chapter 64, and to
certificate the results of the inspection and testing. The dead testing of the installation must precede the live testing to ensure the installation can be energised safely for the first time to perform live testing.
For periodic inspection and testing, the Wiring Regulations do not define any particular tests or a sequence of testing, only that the inspection is supplemented by appropriate tests and measurements set out in Chapter 64. The objective of a periodic inspection and test is set out in Regulation 651.1. This is to determine, so far as practicable, whether the installation is in a satisfactory condition for continued service.
So, the major activity is a thorough inspection followed by testing. The issue of an Electrical Installation Condition Report (EICR), together with schedules on inspection and testing results, is a requirement.
The first activity is to ensure that the person carrying out the testing is qualified and competent to carry out the required inspection and tests and has experience of the particular type of installation to be inspected. A statutory requirement of Regulation 16 of the Electricity at Work Regulations 1989 (EAWR) requires a person carrying out electrical work to be competent.

“The dead testing of the installation must precede the live testing to ensure the installation can be energised safely for the first time to perform live testing.”
Before starting work on site, a risk assessment and method statement should be produced by a person competent to carry out the task in compliance with the Management of Health and Safety at Work Regulations 1999. The results of this process then need to be communicated to the person carrying out the inspection and testing and to any person assisting them. When considering the use of PPE, rubber-soled shoes in good repair and eye protection should be a minimum requirement.
A fundamental task for anyone carrying out work on an electrical
installation is to understand the requirement for safe isolation, as required by Regulations 12, 13 and 14 of the EAWR.
To carry out safe isolation, the inspector will need a 2-pole voltage tester, a non-contact voltage indicator, a clamp meter, a proving unit and a lock off kit.
The Kewtech KT5 2-pole voltage tester will detect a live voltage with one probe if a 2-pole test is carried out and a protective conductor or a neutral is not present, unlike some 2-pole testers that need a potential difference between the probes to detect the presence of a live conductor. It will also measure voltages up to 1000V AC and 1500V DC.
The KT5 has a non-contact voltage detection function which is useful for proving the outside of a distribution board, feed pillar or street cabinet is dead before touching it. It also benefits from a current testing fork that can be used to detect current flowing in protective conductors due to PEN conductor faults.
Kewtech has a range of lock off kits available for a wide range of
installation types, and also supplies a range of five different isolation kits. The Kewtech Kewstick Duo complements the 2-pole tester and is a useful tool for continually proving dead at regular intervals when working on an installation after safe isolation. All Kewtech single and 2-pole testers have fixed thin tips to comply with Health & Safety Executive GS38 requirements.
To carry out installation tests, the inspector can use a range of single function or dual function instruments, or more commonly a multifunction tester (MFT).
Regulation 634.1 of the Wiring Regulations makes a requirement to use instruments complying with the relevant parts of BS EN 61557. The instrument should also be selected for working on LV installations to meet the Cat III requirement of BS EN 61010-1, which is to have a voltage rating of 300-600V with a voltage impulse rating of 4kV. The Kewtech KT66DL meets – and exceeds – these requirements and has functionality to perform a full range of installation tests, including continuity, insulation resistance, low current and high current loop impedance tests both

2 wire and 3 wire, RCD testing, voltage measurement, earth resistance and phase rotation tests.
The KT66DL can perform high current loop tests at 25A for more accurate readings of PFC/PSC when close to a supply transformer. The instrument is ergonomically designed and intuitive to use and is fitted with a neck strap. It is recommended that inspectors use the neck strap at all times to leave both hands free and to prevent accidental damage to the instrument if dropped.

The KT66DL is complemented by a range of test leads, probes and crocodile clips. It is important that the leads, probes and crocodile clips comply with HSE guidance document GS38. The test clips should ideally have parallel jaws with a good ‘bite’ to them to reduce testing errors. When working live on high current supplies it is recommended for safety to use fused probes containing HBC ceramic fuses to reduce the risk of arc flash in the event of an accidental short circuit. Kewtech supplies a wide range of GS38 compliant leads, probes and crocodile clips suitable for both live and dead testing. Kewtech leads are double insulated and have a different colour inner insulation layer to indicate damage to the outer insulation sheath.
Before using any test equipment or test leads, they should be inspected for damage to ensure they are in good working order and the instrument has charged batteries. Regular confidence testing of the instrument and leads is recommended using a range of known resistances for continuity and insulation resistance ranges and a designated socket for loop impedance and RCD testing.
The Kewtech FC2000 Check Box is a convenient way of testing for ongoing accuracy of continuity, insulation resistance, loop impedance and RCD tests. The results of the tests and the date should be recorded to identify any deterioration of the instrument accuracy and leads over a period of time.
Confidence testing is not a substitute for formal calibration testing and it is recommended that this is undertaken yearly and a calibration certificate obtained. Kewtech provides a calibration service for all makes of test instruments in an accredited laboratory.
