From the Editor.
As we near the end of 2024, we find ourselves another step closer to the Government’s 2050 net zero deadline. The final issue of the year provides an opportunity for reflection and GTEC’s Griff Thomas has done just that, with a look at five things 2024 taught us about the journey to net zero on pages 16-18. He stresses that policy needs to align with skills development – a problem industry is keen to address given the well-documented skills shortage.
It is something ESF’s Luke Osborne also highlights in our interview on pages 22-25, explaining that installers must be ‘upskilled’ to ensure they understand the nuances and additional requirements of low-carbon technologies such as solar PV, battery storage, heat pumps, EVs and their charge points, and other smart energy-efficiency solutions.
We’ve drafted in CEF’s Head of Electrotechnical Solutions, Darren Staniforth, to answer your installation questions on such emerging technologies, kicking off with a query about DC isolators in large scale PV installations (page 26). Please send your questions to info@lylamedia.co.uk for Darren’s technical input.
Technologies supporting clean energy and net zero targets were also emphasised in the recent Autumn Budget, delivered by Chancellor of the Exchequer, Rachel Reeves, on 30 October. The first Labour Budget since 2010 received a mixed response from the electrical industry – whilst increased funding for the Boiler Upgrade Scheme, continued support for EVs, and a commitment to the Warm Homes Plan were welcomed, some questioned why the commercial and industrial sectors were not treated with the same amount of prominence as residential decarbonisation. One thing most agreed on was the need to pick up the pace in our energy transition as net zero milestones loom. Read more industry reaction on pages 12-14.

Implications of ISG collapse are far-reaching
ISG went into administration in September, making 2,200 workers redundant with immediate effect. ISG was the sixth largest construction firm in the UK by turnover, with revenues of around £2.2bn. It marked the largest collapse of a UK construction company since Carillion in 2018.
The collapse is set to have farreaching consequences across the industry in the months and even years to come, with the future of many projects left in doubt. According to Glenigan, a construction intelligence provider, ISG has projects totalling over £2.5bn on-site and has been awarded contracts on a further £1.7bn of work – 33 awarded contracts, 57 in-progress projects, and three nearing completion have been left up in the air.
A number of subcontractors
have also been left in a precarious position. Build UK Chief Executive Suzannah Nichol told the BBC’s Today programme that many smaller firms in the supply chain would not receive money, putting their future at risk. Indeed, in recent weeks, the collapse of ISG has been blamed for the fall into administration of lighting contractor, Seventynine Lighting, and glazing specialist, Vitrine Systems, with more feared to follow.
What’s more, newly published filings reveal ISG collapsed with estimated debts of almost £1bn, prompting fresh calls for audit reform.
As the construction industry continues to navigate the fallout from ISG’s demise, Build UK has published a series of FAQs to support organisations in the supply chain that may be affected.
NESO publishes clean power advice to government
National Energy System Operator (NESO) has released comprehensive and independent analysis of how to achieve clean power in 2030.
Commissioned by the Secretary of State for Energy Security and Net Zero, as part of the Government’s mission to make Britain a clean energy superpower, Clean Power 2030 sets out both the challenging hurdles that need to be overcome and the benefits to consumers, the economy and society, including Britain’s energy security, that doing so could deliver.
The analysis shows that overall systems costs should not increase for a clean power system. Other factors could reduce electricity bills in 2030, including a reduction in legacy policy costs (as contracts expire) and energy efficiency improvements. Government policy decisions could also reduce bills by 2030.

EAL pioneers new route for electrical panel builders
EAL, alongside West Nottinghamshire College, ECS and AF Switchgear, has introduced a new qualification route for experienced electrical panel builders to achieve formal recognition through the ECS Gold Card.
Targeted at professionals with over five years of experience, the pathway includes the EAL Level 3 Award in Industrial and Panel Wiring, allowing skilled workers to bypass traditional apprenticeships.

New standard to ensure safety for EV charging equipment
With the increase in EV uptake, the IET is calling for a standardised approach for EV charging equipment dealing with faults on the public low voltage electrical distribution network.
The IET has published a new standard to tackle this, known as Open combined protective and neutral (PEN) conductor detection devices (OPDDs), IET 01:2024. It outlines to manufacturers, specifiers, designers and installers the protection mechanisms for EV charging equipment in case faults occur – such as dangerous voltages on metalwork which could
present a risk of shock –known as an open ‘PEN’ fault.
Current regulations require EV charging equipment to cease charging and completely isolate the vehicle from the charging equipment when a particular fault occurs on the supply cable out in the street. Most manufacturers of EV charging equipment provide this functionality but not all of them do it in the same way. IET 01 seeks to provide a standard way for EV charging equipment to operate with these considerations in mind.

Government funding to launch carbon capture sites
The Government has reached commercial agreement with industry to launch carbon capture in the UK.
Major funding for two carbon capture sites, in Teesside and Merseyside, will directly create 4,000 jobs and support 50,000 jobs in the long-term while powering up the rest of the country.
Carbon capture, usage and storage (CCUS) technology removes CO2 emissions before it reaches the atmosphere and stores it safely beneath the seabed – using tried and tested technology that has been deployed across the globe for over 20 years.
The new carbon capture and CCUS enabled hydrogen projects will help remove over 8.5 million tonnes of carbon emissions each year – the equivalent of taking around four million cars off the road.

‘Biggest uplift in employment rights law since 1970s’ now before Parliament
The Government presented its Employment Rights Bill to Parliament on 11 October as the first phase of delivering its Plan to Make Work Pay. The 150-page bill comprises 28 separate policies accompanied by policy paper Next Steps to Make Work Pay, which sets out the direction of travel in several key areas.
Most decisions are yet to be taken, with detail to be provided through subsequent regulations and codes of practice, and some areas subject to further considerations and consultations. The policy paper notes, “We expect to begin consulting on these reforms in 2025, seeking significant input from all
stakeholders, and anticipate this meaning that the majority of reforms will take effect no earlier than 2026.”
Some of the changes that could be progressed relatively quickly include day one rights, statutory sick pay, flexible working and trade union reforms.
Whilst we await further detail, businesses are advised to consider their probation periods and flexible working policies. Employers who aren’t unionised should prepare for a potential approach. Those who are unionised will need to revisit their arrangements and consider the new protections.

Six towns and cities to pilot clean heating innovation
Businesses and building owners across England are set to benefit from low-cost, low-carbon heating as six towns and cities have been selected to develop the country’s first heat network zones.
Developing zones for heat networks in urban areas is the cheapest and most efficient way of delivering the technology, which recycles excess heat – generated for example by data centres or from factories – to enable the heating of several buildings at once.
The ground-breaking schemes in Leeds, Plymouth, Bristol, Stockport, Sheffield, and two in London will receive a share of £5.8m of government funding to develop the zones, with construction expected to start from 2026. This will help to create tens of thousands of jobs
including engineering, planning, manufacturing and construction roles.
Heat network zones use data to identify the best spots and help to plan and build the technology at scale. They require suitable buildings, such as hotels and large offices, to connect when it is cost-effective for them to do so.
The six selected towns and cities are part of the government’s plan to accelerate the delivery of heat networks across England in areas where zones are likely to be designated in the future. The learnings from these pilots will inform the work to reduce bills, enhance energy security and achieve net zero by 2050.

New scheme to attract investment in renewable energy storage
The Government has launched a new scheme to help build energy storage infrastructure. This could see the first significant long duration energy storage (LDES) facilities in nearly four decades, helping to create back up renewable power and bolster the UK’s energy security.
These technologies work like giant batteries by storing renewable energy and releasing it onto the grid and into homes when needed. This includes pumped storage hydro, which stores electricity by pumping water up a reservoir, to be released later.
Barriers including high upfront costs – despite low operating costs – have held back investment in this critical infrastructure. However, the investment support scheme announced will boost investor confidence and unlock billions in funding for vital projects which will help create thousands of jobs and deliver clean power as the country accelerates to net zero.

2024 best year on record for heat pumps
Microgeneration Certification Scheme (MCS) has announced that 2024 is now officially the best year on record for certified heat pump installations in the UK.
In 2023, the UK saw 40,426 certified heat pump installations between January and December, a record at the time. However, as of early October 2024, the UK has already reached that figure, with over 42,000 installations completed from January to the end of September.
Average monthly heat pump installations have risen by 39% compared to 2023, bringing the current number of certified heat pump installations in the UK to nearly 260,000.

Industry reacts to the 2024 Autumn Budget
Chancellor of the Exchequer, Rachel Reeves, presented her 2024 Autumn Budget to Parliament on 30 October, receiving a mixed response from the electrical sector. With comments on the Warm Homes Plan, Boiler Upgrade Scheme, support for EVs, apprenticeships and skills, and more, here’s what the industry had to say…
Kelly Becker, President, Schneider Electric UK and Ireland, Belgium and Netherlands:
“Schneider Electric welcomes the commitments to deliver an Industrial Strategy and the budget’s commitments to maintaining funding for the Industrial Energy Transformation Fund, the Public Sector Decarbonisation
Scheme, and Made Smarter.
“However, we would have liked to see commitments to supporting the manufacturing supply chain that will play a key role in delivering the industrial and green growth ambitions
set by the Government. Whilst we welcome the support for residential and public sector building decarbonisation, the UK also needs a clear roadmap for decarbonising the commercial and industrial sectors.”
Andrew Eldred, Chief Operating Officer, ECA:
“ECA welcomes the Chancellor’s commitment to invest in industry, housing and electric transport. And her commitment to refocus levy funding away from Masters’ degrees towards trade apprenticeships, as announced earlier this year.
“However, this budget lacks crucial detail on how it will support skills access for smaller firms, which make up 99% of the electrical contracting sector. These businesses will now also carry the higher burden of Employer National Insurance and higher apprentice costs.”
Charlotte Lee, Chief Executive, Heat Pump Association:
“Given the challenging economic climate, it’s promising to see an initial commitment of £3.4bn towards heat decarbonisation and household energy efficiency over the next three years, as well as an increase in funding for the Boiler Upgrade Scheme for the next two years.
“However, more needs to be done to support the acceleration of the electrification of heat if the UK is to stay on track and meet the carbon emission reduction targets in line with the legal obligations.”
James Bamborough, Sustainability and Net Zero Policy Manager, Institution of Engineering and Technology (IET):
“We’re pleased to see that one of the measures in the 2024 Autumn Budget is a review into barriers facing greater adoption of transformative technologies that could enhance innovation and productivity.
“It is also very encouraging to hear the Chancellor deliver £3.4bn for the Warm Homes Plan over the next three years. However, if Britain is to fix the foundations of its housing stock, decarbonise homes, lower energy bills and boost health we must see exactly how this money will be spent.”
Chris Claydon, Chief Executive, JTL Group:
“JTL welcomes much of what has been announced, including support for skills challenges in key sectors which the Government acknowledges is holding back growth across the country. It is imperative that Independent Training Providers can also access the funding pledged to work towards a more level playing field.
“While there is no doubt the sector will rise to the challenge of future demands, we need a systemsthinking approach from the heart of government to get there.”
Paul Smith, MD, NIBE:
“The budget featured some positives for the heat pump sector, including an increase in funding for the Boiler Upgrade Scheme for the next two years, and support to grow the heat pump manufacturing supply chain. Even with these positives, we are still way behind the rest of Europe when it comes to heat pumps.
“It’s time to pick up the pace in our transition from fossil fuels, I hope to see more focus on the ways we can achieve this in the years ahead as the first significant net zero milestones loom.”
Yselkla Farmer, CEO, BEAMA:
“Reaffirming the £3.4bn Warm Homes Plan investment is positive but it is essential the Government fleshes out the practical details of its approach with cost-effective, impactful measures such as on heating controls and improving indoor air quality to protect health.
“Incentivising EV uptake for company cars through tax relief is positive for decarbonising transport and alongside the £2bn for UK EV manufacturing will boost this vital sector. However, the freezing of fuel duty continues to send mixed messages to motorists.”
Beatrice Barleon, Head of Policy and Public Affairs, EngineeringUK:
“We welcome the Chancellor’s commitment to invest in education and skills as a central pillar of the Government’s growth agenda, not least through the creation of Skills England and the announcement of a £40 million pot to develop new foundation and shorter apprenticeships in key sectors.
“Moreover, the announcement of a series of new energy and infrastructure projects, such as green hydrogen plants and carbon capture and storage facilities, underscores the centrality of ensuring an engineering and technology workforce that is fit for the future to achieve the Government’s mission of turning the UK into a clean energy superpower.”
Christophe Williams,
CEO,
Naked Energy:
“Our net zero goals haven’t been properly addressed in the Autumn Budget, and heat decarbonisation has been woefully neglected.
“The Warm Homes Plan is a great scheme for the residential sector, but we need to be treating the commercial and industrial sector with the same amount of prominence. It’s baffling that we’re not seeing much policy on this front as it’s industry that demands the most heat, but is the hardest to decarbonise. It’s here that the Government needs to step in. The continued commitment to the Public Sector Decarbonisation Scheme should be viewed as the bare minimum.”
Thomas
Farquhar, Co-Founder, Heatio:
“On the positive side, funding for heat pumps has been extended as well as key investment supporting domestic manufacturing of the technology. There are also welcome, clear ambitions in the Warm Homes scheme. Encouragingly, the budget continues to incentivise electric vehicles, enabling us to build on the one million EVs already on the road.
“However, it is disappointing that there is nothing new about deploying more lowcarbon tech in British homes; the Clean Heat Market Mechanism is also absent. The lack of action or clarification on the Future Homes Standard is also a missed opportunity.”
Brian Berry, Chief Executive, Federation of Master Builders:
“The Chancellor’s decision to significantly increase employers’ National Insurance contributions will create major headaches for firms looking to take on staff at a time when the building industry is in desperate need of new workers.
“The FMB has been calling for more details of the Government’s plans to improve the energy efficiency of the UK’s homes, a key pledge in Labour’s election manifesto. The announcement of £3.4bn to fund the Warm Homes Plan will be crucial to getting more SME building companies to enter the retrofit market.”
Russell
Dean, Deputy Divisional Manager, Living Environmental Systems, Mitsubishi Electric:
“The investment into Great British Energy and the Warm Homes Plan is a welcome step. But we urge the Government to go further in outlining a clear, long-term strategy to reach net zero.
“The Government’s commitment to building 1.5 million new homes is welcome, but these new homes must be futureproofed, through initiatives like the Future Homes Standard, and not need retrofitting in just a few years as standards change. We must also do more to convey urgency around the need for house builders to prioritise renewables now.”
Five things 2024 taught us about the journey to net zero
Griff Thomas Managing Director of GTEC and Heatly
Climate change was a key issue for UK voters in the 2024 general election.
Polling by More in Common after the vote confirmed that former Prime Minister Rishi Sunak’s watering down of climate policy in the lead up to the election did indeed cost him votes, and we all know what happened next; Labour ended up taking a House of Commons majority of 172, leaving the Conservatives with their lowest ever number of seats and Keir Starmer in Number 10.
With so much political instability and backtracking of climate deadlines over the last five years, Labour now have their work cut out. Can they kickstart economic growth and make Britain a ‘clean energy superpower’ as promised in their manifesto?
As we come to the end of a year that saw the Labour party return to government for the first time in 14 years, Griff Thomas, Managing Director of GTEC and Heatly, both part of the United Living Group, looks back at 2024 to see what we’ve learned about the journey to net zero.
Here are five key lessons we’ve learned about decarbonising the UK’s infrastructure and energy landscape in 2024.
1. Heat pumps are the primary means of domestic decarbonisation
The debate about the role of hydrogen in domestic decarbonisation has been rumbling for many years but in May this year, it was confirmed that heat pumps, together with heat networks, will be the primary low carbon heating source in UK homes. The Department of Energy Security and Net Zero (DESNZ) announced the cancellation of the final hydrogen town trial pending strategy decisions about the future of the gas grid in 2026. Low carbon hydrogen may play a limited role in domestic heating, however, the Government is positively underpinning heat pumps and district heating going forwards.
Since the Boiler Upgrade Scheme (BUS) funding was raised to £7,500 there has been a massive uptick in interest, which shows the appetite for heat pumps is there if the price is right. In a clear sign of support
“Can Labour kickstart economic growth and make Britain a ‘clean energy superpower’ as promised in their manifesto?”
for consumers and businesses operating in the heat pump industry, the Government has approved the overallocation of BUS vouchers for this financial year. 2025 is set to be a big year for heat pumps.
2. We need political stability to build confidence in net zero
The Labour Party’s return to government brought renewed commitment to climate action, including lifting the ban on onshore wind and a pledge to end new oil and gas licences. In his first major speech, Foreign Secretary David Lammy highlighted how deeply the issue of climate change is intertwined with national security and economic stability, expressing a keenness for the UK to lead the charge in this area. This stark and serious messaging was refreshing to hear, a very different approach to the previous government. I hope we now see some consistent and robust policy to support sustainable growth of clean energy – Great British Energy is a promising start.

“For too long, slanderous views surrounding the shift away from fossil fuels have been allowed to erode trust in decarbonisation and interrupt progress.”
There is also a lot of work to be done on countering the misinformation and fearmongering surrounding heat pumps. For too long, slanderous views surrounding the shift away from fossil fuels have been allowed to erode trust in decarbonisation and interrupt progress. Net zero is a cross-party issue, not a political tool or something to stoke divisions in the ‘culture wars’. What we need now is for our policy makers to lay a strong foundation and stick to the programme – I would like to see a 10year plan for the path ahead.
3. Investment in carbon capture is gaining momentum
As a proud Northerner, I was delighted to hear that the Government is investing in two new carbon capture sites – a first for the UK – creating thousands of skilled jobs in the North of England, in the same week that the UK became the first industrialised nation to end coal usage.
The new projects in Teesside and Merseyside will set the UK on course to be a global leader in hydrogen and carbon capture, utilisation and
storage (CCUS), removing carbon emissions equivalent to four million cars each year and injecting £8 billion of private investment into the North of England.
Although the role of hydrogen in heating is likely to be limited, it holds huge potential in key hardto-treat sectors, such as energy storage and transportation, where it can be used for heavy duty haulage where batteries are unsuitable. For contractors, this means staying informed about carbon capture technology and the evolving hydrogen market, as these innovations will play a critical role in reducing emissions in the coming decades.
4. Policy needs to align with skills development Labour’s green initiatives, including the Warm Homes Plan, call for mass deployment of energy efficient technologies across homes and public buildings but the skills gap remains a significant barrier. While I applaud these bold initiatives, they must be backed by funding for skills development to ensure measures are delivered.
The launch of Skills England is a positive step and, for those in the low carbon sector, their first report made for exciting reading. Acknowledging that employee investment has been in steady decline for too long, the report outlined apprenticeship reforms and a ‘bottom-up’ approach to training that should provide more flexibility for employers and learners.
I also hope that next year, reforms in the accreditation process for heat pumps and renewable energy technologies will remove barriers of entry to the market for installers –
we urgently need more heat pump engineers and solar PV and battery storage to prevent further delays.
5. Technology is key to achieving sustainability goals
Investment in skills and tech is crucial for every sector and holds great potential for the low carbon transition. If we can use artificial intelligence and real-time data from heat pump system monitoring, we can gain insight into energy efficiency, performance and user behaviour that can help optimise design and inform fit-for-purpose low carbon heating policy.
New digital tools will also help installers dramatically improve the ease, speed and accuracy of heat pump system design while delivering critical support to streamline the transition from gas to heat pumps, something that I am personally involved with in the development of Heatly. Installer trials are ongoing and we’re also forging partnerships with bigger organisations interested in using Heatly’s functionality to improve their own operations – including energy providers, wholesalers and manufacturers.
Technology also has a role beyond the industry, building trust and confidence in consumers. Using intelligent apps like Heatly, consumers can access reliable information, compare energy tariffs, track their energy usage and understand the benefits of transitioning to low carbon heating, which will be instrumental in countering disinformation and turning the tide on the perception of renewable technologies.
With a new government in power, this year has marked a shift in our approach to economic growth and industrial strategy. For those in the commercial building services sector, the change brings opportunities –whether through upskilling, adopting new technologies or adapting to meet emerging markets. Labour has made some positive moves towards net zero, it’s important that they now stick to the plan to ensure progress continues steadily into 2025 and beyond.

Sit down with: ESF’s
Luke Osborne
Meet Luke
Luke Osborne joined ESF as Deputy Technical Director in October 2023. Prior to that, Luke was Energy and Emerging Technologies Solutions Advisor at the Electrical Contractors’ Association (ECA), covering areas such as renewable energy and storage, electric vehicles, energy efficiency, and emerging energy trends, as well as advising on energy policy issues.
The electrical industry is undergoing rapid growth, fuelled by the UK’s ambitious net zero goals and increasing demand for sustainable energy solutions. “The drive for sustainability coupled with increased fuel prices has led to a rapid change in the demand for lowcarbon technologies (LCT), including solar PV, battery storage, heat pumps, electric vehicles and their charge points, along with an array of smart energy-efficiency solutions,” explains Luke. This significant growth has quickly changed the landscape of the electrical industry, with “the electrician and the consumer now inhabiting a very different world to that 10-15 years ago”.
Electrical Safety First (ESF) works closely with industry, government and others to improve electrical safety regulations and standards, supporting the delivery of safe, compliant installations in a rapidly evolving electrical world. Electrotechnical News caught up with ESF’s Deputy Technical Director, Luke Osborne, to find out more.
Whilst this shift creates huge opportunities for installers, “it is essential that they are ‘upskilled’ to ensure they understand the nuances and additional requirements of these technologies”. Worryingly, a recent Building Engineering Business Survey found that electrotechnical and engineering services businesses are struggling to find suitably qualified candidates to fill vacancies in their organisations, with almost half (46%) of the respondents currently looking to fill vacancies in their organisations and, of those, 46% saying applicants consistently lack sufficient knowledge or skills for the job.
Emerging technologies
In terms of the ‘additional requirements’ of these emerging technologies, Luke explains that, as with all electrical installations, the correct design, selection and erection of equipment is paramount. “Where previously, many circuits had low loads at short durations, many LCTs exhibit high loads (or supply) for long durations. An EV charge point could be pulling a constant 16-32 amps over a number of hours and if the cables and supportive switchgear and protective devices are not suitable, there may be distinct safety issues. Similarly, PV and battery storage may be providing significant energy over a long period of time.
“Additionally, due to the increased exposure the end user may have with these technologies, additional
“The recent release of Amendment 3 highlighted that some RCDs and over-current devices may be adversely affected by bidirectional energy flows, as presented by solar PV and battery storage systems.”
safety devices need to be considered, providing protection against potential open-PEN faults and selecting the right kind of RCD that is impervious to potential levels of DC earth leakage current that can blind certain RCD devices. This is before we even consider the additional earthing requirements for an islanded prosumer’s electrical installation (Chapter 82 of BS 7671).
“The recent release of Amendment 3 of BS 7671 highlighted that some RCDs and over-current devices may be adversely affected by bidirectional energy flows, as presented by solar PV and battery storage systems and must be selected accordingly. This obviously raises queries regarding existing installations and the current ESF WRAG questions and answers provide guidance on this.”
Wiring Regulations Advisory Group WRAG, which stands for Wiring Regulations Advisory Group, provides guidance on the interpretation and application of the Wiring Regulations, and ESF plays a key role as the host of the group – just one of the many
“As we move to an increasingly smart-enabled and connected world and with the majority of our devices being DC powered, there is a whole world of opportunities and potential changes ahead of us.”
ways the charity is supporting industry through the energy transition.
Indeed, with the growing adoption of technologies such as EVs, solar panels and heat pumps, addressing emerging issues and ensuring the guidance is up-to-date is of the utmost importance. “Our involvement
ensures that electrical professionals receive clear and consistent advice, supporting safe and compliant installations in a rapidly evolving industry,” says Luke. “Whilst ESF hosts WRAG, the questions and answers are created collaboratively with a range of industry stakeholders, all inputting their time, knowledge and experience for the ‘greater good’. Without their contributions, WRAG simply wouldn’t be possible, nor would it have the buy-in and support from industry. This also ensures that the information provided is agreed upon through an industry consensus.”
The next amendment to the Wiring Regulations – known as Amendment 4 – is expected to be published in 2026, with each area of change described by the IET as ‘a response to fast evolving technologies’. Luke says, “Power-over-ethernet (PoE), that ability to provide both power and data over a common cable, is an interesting addition to Amendment 4, with good reason. As we move to an increasingly smart-enabled and connected world and with the majority of our devices being DC
powered, there is a whole world of opportunities and potential changes ahead of us. As with everything, an understanding of the implications and safety considerations is vital.”

PV installations and DC isolators
Is it correct to reduce the amount of DC isolators in large scale PV installations to reduce the number of possible risks associated with DC fires?
In April 2024 a report was produced by the Fire Protection Association that looked at the installation of solar PV systems in commercial installations. It highlighted that the number of fires directly linked to PV installations is relatively low, however, its findings confirmed where fires do occur, 48% of those are related to the DC isolators.
Need some technical advice?
Darren is here to help! Send your questions to info@lylamedia.co.uk
It’s true to say a designer could reduce the fire risk by removing the isolators, but this should only be considered if the inverter allows connection of the PV strings via carefully selected solar PV connectors.
Looking closely at the problems associated with the installation of DC isolators, care must be used
when selecting and installing them. Many of the problems found are considered to be:
· Incorrectly sized.
Lack of IP rating after installation.
Lack of maintenance.
A carefully selected, installed and maintained DC isolator can provide highly effective means of isolation for maintenance of the inverter, or future testing of the solar PV strings.
In conclusion, DC isolations can be very useful in solar PV systems if they are designed, selected and installed correctly. However, if an inverter has the ability to accept connection of the PV string using solar PV connectors, the designer could remove the DC string isolators from their design, thereby reducing the potential problems associated with the devices.

Mode 4 EV charging: AC side RCD selection
In this technical article, Chaz Andrews, Technical Manager at Doepke UK, discusses RCD circuit protection associated with Mode 4 charging equipment.
Chaz Andrews Technical Manager at Doepke UK
If you are involved in regular installation of DC EV chargers, you will already be familiar with the significant differences between individual manufacturers’ performance characteristics and the impact on the supply side equipment e.g. transient inrush current, harmonic distortion, leakage current and associated RCD selection.
Mode 4 guidance
It is not possible to give standardised recommendations for RCDs
associated with Mode 4 chargers –why?
Whilst there has been agreement for Mode 3 charging standards in Europe, with the publication of EN IEC 61851-1 2017, and the associated changes in Section 722 of BS 7671, that is not the case with Mode 4 charging standards which are still coalescing.
DC charger design is far more complex due to the safety issues associated with high DC voltage/ current. This is reflected in the time taken to agree a revision of BS EN IEC 61851-23 2014 – the current designated standard for DC charging, quoted in BS 7671. For example, this early standard gives general design requirements but is light on standardised test
methods for checking conformity. This results in a wide variation in basic standardised performance characteristics between individual manufacturers claiming compliance with a designated standard.
Which standard?
The current edition of BS 7671 Clause 722.531.3.101 relating to RCD selection Note 2 states that supplies using DC vehicle connectors to the BS EN 62196 series are under consideration.
Electrical safety design characteristics (the guts of the charger) may be dependent on the DC interface charging technology adopted by the vehicle manufacturer e.g. CHAdeMO (Japanese), GB/T (China), CCS 1 & 2 (North America & Europe), and Tesla (proprietary design NACS – based on North

American standards). Later versions of Tesla DC chargers were supplied with CSS2 interface (compatibility with European EVs), but still NA electrical design standards.
Use the basic principles of BS 7671 (Clause 133.1, 134.1.1 and 531.3.3) to select appropriate RCDs based on the individual chargepoint manufacturer’s characteristics and installation recommendations, e.g. note minimum RCD characteristic requirements at the quotation stage*.
* Clause 642 (Inspection): Refer to as an aide-memoire during installation planning/equipment verification.
Mode 4 chargers – general points
RCDs installed on the AC supply feeding the charger do not provide protection on the DC side of the charger. Electric shock and fault protection on the DC side is the responsibility of the chargepoint manufacturer. Conformity with the essential safety requirements is indicated by CE/UKCA marking – see Clause 642. Refer to the chargepoint manufacturer’s installation instructions.
Inrush/transient currents
Depending on the design and technology employed, equipment containing high power rectifiers/ inverters can produce significant transients during operation. Check with the equipment manufacturer –RCDs may require transient resistant
features to prevent unwanted tripping and unnecessary equipment downtime.
AC leakage current
This is the current that flows to earth during normal operation. Leakage current values are specific to the manufacturer’s design and will vary as a function of the individual chargepoint harmonics, produced during various stages of charging and the supply quality (existing harmonic content).
The existing standard BS EN IEC 61851-23 sets minimum protective conductor requirements for Class 1 equipment, where touch currents exceed 3.5 mA. Follow the manufacturer’s recommendations if they exceed the requirements of BS 7671 543.1 – 543.7.
Unexplained RCD tripping may be the result of insufficient safety margin between the operational leakage current and the RCD sensitivity – see 531.3.2 (ii), or incorrect RCD selection, i.e. RCD used outside of its design range (explained below) – see 531.3.3.
Safety/departure from BS 7671
Type A RCDs are calibrated/designed to detect leakage currents at the supply frequency f. The equipment contained in the DC charger produces leakage currents at frequencies >> f. Leakage currents generated at higher frequencies change the RCD tripping
“This early standard gives general design requirements but is light on standardised test methods for checking conformity.”
characteristics. In this case, Clause 133.1.3 applies, and the designer must verify that the RCD provides the same degree of safety as Clause 133.1.1, i.e. obtain information from the manufacturer confirming that the RCD will still function reliably when subjected to high frequency leakage currents.
Note the wording in Clause 133.1.3: “Such use shall be recorded on the appropriate electrical certification specified in Part 6”.
Until recommendations are included in BS 7671-722, unless otherwise stated in the chargepoint manufacturer’s installation instructions, only Type B RCDs (RCCB, RCBO, CBR) should be used upstream of Mode 4 chargepoints –reference 531.3.3 (iv).
Conclusion
With any innovative technology the ‘state of the art’ is an important concept to consider in relation to the existing requirements of BS 7671 and installation advice provided by the equipment manufacturer.
Ask before acting and keep in mind the requirements of Clause 133.1.1 – 3, 134.1.1, and 531.3.2 – 3.
Tackling the myths of recycled materials
The use of virgin materials over recycled options is not only depleting our finite natural resources but also increasing the embodied carbon of buildings and contributing to the huge issue of construction waste. Jon Chamberlain, Managing Director of Marshall-Tufflex, explains the positive impact that reclaimed materials can have.
Jon Chamberlain Managing Director of Marshall-Tufflex
While steps have been taken in recent decades, global consumption of natural resources is still increasing. In fact, research suggests that plastic use in G20 countries is set to nearly double by 2050 unless meaningful action is taken to reverse the trend.
The built environment is both a considerable consumer of raw materials and major source of carbon emissions. However, relatively small changes across the industry can have a large positive effect. It is estimated that establishing a circular economy of reclamation, reuse and recycling of building materials could reduce global CO2 emissions from materials by 38% by 2050.
In the electrical sector specifically, one of the areas where contractors can contribute to circularity is by promoting the use of cable management systems manufactured from recycled materials. Although the demand for products with recycled content is clearly growing, there are still some key misconceptions.
Quality
A common assumption is that recycled PVC-U products are of a lower quality – and therefore less durable – than those produced
from virgin-grade PVC-U. This is simply not correct and, as with all components, choosing products from a reputable, experienced manufacturer is the most important factor in ensuring quality.
The recycled PVC-U that goes into Marshall-Tufflex products primarily comes from reclaimed PVC-U window frames. This is a high-quality grade of PVC-U as it was designed to withstand UV light and external elements. This results in cable management systems of the same, if not a higher, standard.
Colour and finish
One of the concerns we often see is that products with recycled content will not provide the same aesthetic as less sustainable options. Again, this is no longer the case given modern manufacturing methods, especially if the cable management is
sourced from a manufacturer that has invested in refining these techniques. For example, the manufacturer may optimise the balance of recycled and virgin material to use as much reclaimed PVC-U as possible while delivering a glossy, white and consistent finish.
“For some components such as the unseen trunking base, it is possible to use 100% recycled content with no impact on the final aesthetic.”
Commercial considerations
In addition, for some components such as the unseen trunking base, it is possible to use 100% recycled content with no impact on the final aesthetic.
Another misconception is that sustainable products are more expensive. However, the cost of products manufactured from recycled material should be in line with others of the same quality. A further benefit is the competitive edge gained by contractors that can offer responsibly sourced products, especially as sustainability is an increasingly important element of any major tender, often now at the pre-qualification stage.
Contrary to what is often believed, cable management systems with
recycled content can deliver the required performance with no impact on cost. By encouraging customers to switch to these products, contractors can help minimise the environmental impact of new and refurbished buildings.

Lighting industry backs its environmental claims with data
The conference and exhibition, held on 9 October in London, was packed with new information, initiatives and updates on all issues related to sustainability and lighting.
New legislation
Lutron’s Neil McLean gave a comprehensive update on the approaches being taken by the EU and UK to drive greater sustainability and a circular economy. He summarised the requirements of new legislation planned by the EU and said that the new UK government had already signalled its intention to put in place new circular economy policies.
New environmental metrics
One of the key themes to emerge throughout the day was the growing importance of Life Cycle Assessments (LCAs) and Environmental Product Declarations (EPDs) for the lighting industry.
Many of the delegates identified that action on LCAs and EPDs would be an important part of their strategy in the future. Max Robson of Recolight described the company’s new LCA and EPD service, provided in partnership with One Click LCA, which includes an online portal for data entry and a dedicated luminaire
The lighting sector is embracing verified data on its sustainability claims, including Environmental Product Declarations (EPDs). That was a key lesson from the recent Circular Lighting Live 2024 in London.
tool that streamlines the process –and minimises the cost – of getting an EPD verified and published.
New approaches to remanufacture
F Mark’s Simon Fisher presented real world examples of successful lighting remanufacture projects, together with the associated energy, embodied carbon, and waste reduction metrics. He listed the critical factors needed to make remanufacture successful.
Nigel Harvey of Recolight presented a re-working of the waste hierarchy, for use as an aid to sustainable decision making in lighting projects, with a focus on maximising the reuse and remanufacture of lighting products, and minimising unnecessary recycling.
Circular Lighting Live 2025
Next year’s event will be held on 25 September 2025, at a newer and larger venue in central London.
What the delegates said
Greg Bristol of ASD Lighting said: “CLL2024 was a fantastic event. I came away awed by the challenge but inspired by the amazing people and companies working towards a more sustainable industry.”
Martin Wherry of Glamox said: “Circular Lighting Live 2024 was an inspiring and essential gathering. It showcased how the industry is coming together to innovate around circularity, pushing the boundaries of sustainable lighting design while embracing AI and digitalisation. The focus on reuse and refurbishment is exactly the kind of forward-thinking approach our sector needs to achieve net zero goals.”
Simon Fisher of F Mark said: “If you are into lighting, sustainability and the built environment, this is THE event to be going to every year!”
Looking ahead to a bright and sustainable future
Andy Pagett NVC Lighting’s Chief Operating Officer
The growing need for sustainability to be a key item on the business agenda is having a huge impact on how lighting manufacturers and distributors do business. From new product development, to supply chain relationships and day-to-day operational activities, there is a sharp, shared focus on how to deliver environmental efficiencies whilst maintaining the highest quality of product and service.
Government-set targets state that businesses are expected to contribute to halving greenhouse gas emissions
by 2030 compared to 1990 levels, which involves improving energy efficiency, adopting cleaner technologies, and using renewable energy sources.
As we move into 2025, NVC Lighting has positioned itself as a leader in creating innovative lighting solutions for use across a huge range of sectors and appliances, whilst making great strides with regards to sustainability.
Whether that is putting time and resource into reducing our carbon footprint in line with government targets, shining a light inward on our products and their performance or working with collaborators in our supply chain to create fresh solutions, we’ve been proactive in playing our part in building a bright and sustainable future.
With a new year on the horizon, here’s some insight into what we’ve achieved so far.
Carbon footprint
NVC Lighting’s sustainability journey began in earnest in 2019. As will be the case with many other organisations across many different sectors, we had tried to make efficiencies where possible but may have been able to attack the issue more aggressively prior to this point.
However, with wider societal awareness of the importance of sustainability growing by the day, we decided to up the ante.
Achieving ISO 9001 certification in July 2020 and becoming a zero landfill site soon after was a great start, followed by securing ISO 14001 certification in 2021, setting the stage for a deeper focus on environmental impact, including partnering with Carbon Neutral Britain to accurately assess our carbon footprint, which was calculated at 462 tonnes annually.
NVC Lighting’s Chief Operating Officer, Andy Pagett, looks back on the brand’s recent successes in the world of sustainability, and forward to what lies ahead in the new year.
We are committed to reducing this figure by half by 2030, in line with government targets and currently sit well on course to achieve this ahead of schedule.
Operational efficiency
With a greater understanding of our base level carbon output, several credible milestones hit, and some partnerships secured to monitor the latest trends and developments, we moved into assessing the impact of a sharpened focus on operational changes.
Promisingly, a number of simple but effective changes – such as optimising the lighting in our warehouse with motion sensors and introducing electric company cars – made a fast impact, already contributing to a near 100 tonne reduction in our carbon output.
Beyond this, advanced stock management techniques, powered by historical data and predictive algorithms, have enabled us to reduce stockholding whilst maintaining an impressive >99% order fulfilment rate. The fact that this is a possibility at
“NVC Lighting is on track to meet the Government’s 2030 targets by mid-2025, five years ahead of schedule.”
all is a key indicator of the strides which have been made towards a sustainability first mindset across the whole business.
As well as stockholding, packaging innovations have also contributed to our success. By reducing packaging materials and replacing paper instructions with QR codes, we have been able to find another way to contribute towards lowering the carbon impact of our logistics processes.
2025 and beyond
Thanks to these initiatives, NVC Lighting is on track to meet the Government’s 2030 targets by mid2025, five years ahead of schedule.
But why stop there? Our future plans include the installation of solar panels and the rollout of electric vans, along with employee incentives for switching to electric vehicles and cycle to work schemes.
Our successes proven through our commitment to sustainability reflect NVC Lighting’s broader philosophy – providing the most innovative solutions with a focus on quality, whilst remaining competitive in a market where cost will always be a key factor.
We believe that 2025 is going to be a huge year for sustainability development in the lighting industry. We can’t wait to share our success and milestones as we go, and look forward to seeing others make continued progress for the greater good.

Smart HVAC: redefining comfort and efficiency for the future
Shaun Hurworth, Marketing Director at Dimplex UK, discusses the future of smart HVAC technology, exploring how the latest innovations are reshaping the way we experience comfort, efficiency and sustainability in our homes and businesses.
Shaun Hurworth Marketing Director, Dimplex
The UK’s smart HVAC market is poised for strong growth, with forecasts indicating an annual increase of 7.7% between 2023 and 2028. This boom is largely driven by rising energy costs, a growing emphasis on sustainability, and advances in smart technology. These innovations enable consumers and businesses alike to optimise their energy use, creating environments that are both comfortable and sustainable.
One of the most exciting advancements in this space is the rise of intelligent climate control systems, like Dimplex Control. These systems harness predictive algorithms and machine learning to anticipate users’ climate preferences, automatically adjusting settings for maximum comfort while minimising energy consumption. This proactive approach ensures homes remain cozy and efficient without the need for constant manual input.
User experience
Dimplex Control forms the foundation for a comprehensive whole-home smart heating solution. With products like the Quantum HHR storage heater, Edel hot water heat pump, and Q-Rad electric radiator all connected to this platform, homeowners can seamlessly manage their heating and hot water
systems. This integrated ecosystem also provides access to smart energy tariffs, enabling users to capitalise on off-peak energy rates, further reducing costs and environmental impact.
The Dimplex Alta Wi-Fi panel heater expands the smart ecosystem even further by offering compatibility with smart home platforms like Alexa. This means users can control their heating systems alongside other devices such as lighting and security, streamlining home management while improving energy efficiency. The ability to sync various systems through smart technology results in significant energy savings, helping reduce both costs and carbon emissions.
User experience is another cornerstone of modern HVAC innovation. Remote access, voice activation, and adaptive learning capabilities – such as those found in the Q-Rad electric radiator – make it easier than ever for homeowners to control their climate settings. By learning user habits, these systems automatically adjust heating patterns, reducing energy use in unoccupied spaces while ensuring comfort when it matters most.
Smart energy management
Beyond comfort and convenience, sustainability is a key driver in the development of smart HVAC technology. With heating accounting for a significant portion of the UK’s carbon emissions, energy-efficient systems are vital to achieving climate targets. Dimplex’s air source heat pumps (ASHPs) are an excellent
example, as they leverage renewable energy from the air to heat homes, significantly reducing reliance on fossil fuels.
Future-proofing HVAC systems is essential for long-term efficiency and adaptability. Dimplex products are designed with scalability in mind, allowing them to integrate seamlessly into a smart home ecosystem. The modular nature of the Dimplex Control platform means
“By learning user habits, these systems automatically adjust heating patterns, reducing energy use in unoccupied spaces while ensuring comfort when it matters most.”
users can upgrade their systems over time without requiring costly replacements. For instance, the Quantum and Edel systems can be paired together to create an energyefficient solution that evolves with the household’s needs.
As consumers become increasingly aware of the benefits, demand for smart HVAC systems will continue to rise. Quantum HHR storage heaters, which use off-peak energy to
efficiently heat homes, exemplify how smart technology can drive energy savings while maintaining comfort. These systems’ ability to adapt to shifting energy demands positions them as a key component in the future of smart energy management.

Advanced electrical solutions can greatly enhance independence and quality of life for elderly residents, says Kevin Lenton, ABB’s Product Marketing Director for Smart Buildings
Kevin Lenton Product Marketing Director for Smart Buildings, ABB
The UK is undergoing a significant demographic transformation. By 2043, the United Nations forecasts that nearly a quarter of the population will be 65 years or older. This impending reality highlights an urgent need for housing solutions tailored to an ageing population.
Meanwhile, the English Housing Survey (2020-21) reveals that 1.1 million older adults live in homes that fail to meet the Decent Homes Standard, often plagued by inadequate energy performance, dampness, and cold conditions. Poor housing increases health risks and imposes significant financial burdens on the NHS and taxpayers.
To address this issue, Cartwright Pickard and The Helen Hamlyn Centre for Design are developing ageinclusive design principles for later living housing in the UK. ABB is a key technology partner in this project’s Knowledge Transfer Partnership (KTP), supported by Innovate UK.
Technology plays a big role
The project’s goal is to give older adults the opportunity to live independently for as long as possible through sustainable and adaptable design solutions tailored to the UK’s climate.
Initial research led to the development of 18 design principles focused on improving cognitive and
“The study highlights smart technology’s role in enhancing living standards through climate control, automated lighting, and security systems.”
sensory wellbeing by incorporating global best practices for ageingfriendly housing. The study also highlights smart technology’s role in enhancing living standards through climate control, automated lighting, and security systems.
This is where ABB comes in. Our home automation systems can automatically switch off radiators, pre-programme heating times, and allow residents to use voice commands through smart assistants like Alexa. These technologies significantly enhance the living conditions for older adults.
Seamless integration
An integrated approach allows for the straightforward addition of new
assisted living tools to existing systems. For instance, actuators in doors can enhance independence, while wall-mounted controllers enable easy management of lighting and appliances.
Futureproofing through structured wiring supports the addition of smart technologies, facilitating the integration of sensors, smart switches, and motorised actuators. This system simplifies adding assisted living tools to the KNX network, using adaptable standards like OpenAPI and Matter.
ABB’s i-bus KNX system is compatible with various smart speakers, allowing for effortless voice control integration via software updates. This flexibility
ensures that homes can adapt to residents’ evolving needs, continually enhancing living conditions.
Energy and safety measures
Energy efficiency is crucial given rising utility costs. ABB’s passive infrared (PIR) sensors conserve energy by turning off heating and lighting in unoccupied rooms and can alert care teams if needed. Their technology also prevents simultaneous heating and cooling, and adjusts for open windows, further reducing energy waste.
Safety is another critical aspect enhanced by ABB’s technology. Emergency lighting systems self-test and notify the facilities team of any luminaires or battery issues, adhering to building safety regulations without the need for regular manual inspections.
A future-proof solution
While ABB’s technology enhances life for older adults, it complements a broader approach. The 18 design principles ensure access to amenities, integrate nature, and create healthy, independent living environments. This strategy addresses immediate housing needs and sets new standards for sustainable, quality later living housing across the UK.
Smart student accommodation
Glengall Road student accommodation is a modern and well-situated housing option for students studying in London. Located in the vibrant and multi-cultural area of Southwark, this accommodation is ideal for students attending various universities in the capital.
With its proximity to higher education institutions such as King’s College London, the London School of Economics and University College London, Glengall Road offers convenience and accessibility for both domestic and international students.
When Glengall Road student accommodation in Southwark called for the installation of a smart building control system, RAW Controls Ltd was on hand to deliver an energy efficient solution that provides a comfortable environment for occupants.
Project life
The project had a difficult start. The initial brief and proposal was presented to the client in 2021 and the project went through the usual bid and design process by the contractor market. JB Hopkins (M&E) Design & Build Contractor were awarded the contract in November 2023. JB Hopkins started pre-construction activities upon appointment and started physical works on site in December 2023.
The client’s brief was to provide a smart building control system for the new build to ensure an energy efficient development. JB Hopkins carried out a number of reviews within their supply chain to enable them to select the most innovative and installation efficient solution as programme delivery was a key factor and a modular plug and play system was their preferred route.
As RAW Controls Ltd had initially looked at the original design, we were approached to see if we could provide a solution that could meet, if not exceed, the client’s design brief expectations. After many hours of design and research we created a solution that not only met the original brief, but surpassed the original specification whilst enabling the first fix elements of the smart building solution to be integrated quickly into JB Hopkins’ design, which assisted the fast start on the project.
The solution
The solution involved creating a bespoke wireless thermostat with integrated CO2 sensor. This product is wireless enabled and communicates to the smart hub to share logic and provide feedback of the room status and heat demand to the central plant and building management system (BMS).
Integrating a PIR with wireless humidity and occupancy data provided essential environmental information to control the bathroom ventilation.
Operation overview
With the lighting being turned on and off by wireless switches by the door and bed, the presence sensor in the
bedroom and bathroom allows the lighting to be switched off and the heating turned down/off when the room is unoccupied.
Linking the air quality and humidity to the smart hub has also created added benefits by increasing the ventilation to the room if the air quality is below the threshold.
For added protection to the building we installed a rope-based leak detection system under the bathroom pod floor to provide early warning of leaks. The leak detection system communicates wirelessly to the smart hub and then to the maintenance
Line diagram of solution department to alert them of issues.
In order for the student to have control of the temperature and lighting on their smart device, an app was created to enable them to interact with the lighting and heating within the room. This is only active when the occupant is in the room for security and energy issues.
Summary
Glengall Road has become an exemplary smart student accommodation project that will provide not only a comfortable environment for the students, but also an energy efficient solution for the building owner/operator.
