From the Editor
As the cover indicates, this issue looks at the growing concern of poor indoor air quality (IAQ), with Dimplex exploring the importance of maintaining optimal IAQ and creating healthier living spaces (pages 40-41). According to the results of a BEAMA survey, 65% of UK homes experience indoor air pollution, with Public Health England warning that poor IAQ can contribute to respiratory infections, heart disease and even lung cancer. What’s more, data from the Warm This Winter campaign found that 29% of UK residents frequently or occasionally experience mould in their homes. With Awaab’s Law set to come into force from October, Vent-Axia looks at the electrical sector’s role in tackling damp and mould (pages 42-44).
We’re pleased to welcome CEF’s Andrew Moseley as our Guest Editor this issue. After an introduction (page 6), Andrew offers comments and insights throughout the magazine and provides an update on CEF’s sustainability and social value initiatives (page 26). Continuing the theme of sustainability, NVC Lighting explains why Environmental Product Declarations (EPDs) are becoming an essential part of the sustainability conversation (page 28), and LEDVANCE discusses its mission to transform the lighting industry into a greener one (pages 30-31).
Earlier this year, the ‘Sunshine Bill’ – officially known as the New Homes (Solar Generation) Bill – was rejected by government at its second reading. The proposed bill required all new homes to be fitted with mandatory solar panels, but according to myenergi’s Lee Sutton, the decision will do little to slow down the monumental rise of microgeneration (pages 14-16). Indeed, the latest MCS data shows that 2025 continues to be a record-breaking year for renewables (page 12), with solar PV installations in March 2025 increasing by 49% compared to March last year, heat pump installations by 22% and battery storage installations by 147% as the number of people adopting low-carbon alternatives continues to grow.

UMore homes to get energy saving upgrades
p to 170,000 homes in England will benefit from energy efficiency upgrades as the rollout of the Warm Homes Plan gathers pace, helping more families lower their energy bills and improve their homes.
£1.8 billion in government support will be allocated to local authorities and social housing providers, in a new boost which will support them to deliver warmer, more energy efficient homes. This funding will be targeted towards low-income households and tenants living in social housing, with thousands of families set to receive energy performance and clean heating upgrades in the form of insulation, solar panels and heat pumps.
At a time when many are experiencing high energy bills driven by the UK’s reliance on international gas markets, this funding through the Warm Homes: Local Grant and the Warm Homes: Social Housing Fund schemes could now help households save hundreds of pounds a year. This move will help deliver a milestone of higher living standards in every part of the UK by the end of parliament, by boosting people’s Real Household Disposable Income – a key part of the
government’s Plan for Change.
Minister for Energy Consumers, Miatta Fahnbulleh, said, “Living in a warm, comfortable home should not be a luxury. It is a right that has been out of reach for too many people for too long.
“By giving this funding to local authorities and social housing
providers we are delivering on our promise to improve the homes of thousands of people across England. As part of our Plan for Change, we are powering on with our Warm Homes Plan, upgrading cold and draughty homes so they are warmer, cleaner and cheaper to live in.”

ZEV mandate: a missed opportunity for faster
progress
The UK government has published its response to the zero emission vehicle (ZEV) mandate consultation, setting out proposed targets for the proportion of new cars and vans sold that must be zero-emission each year up to 2030/35.
While BEAMA welcomes the long-awaited outcome for the automotive sector and associated industries, its members have expressed disappointment that hybrid electric vehicles (HEVs) continue to play a significant role within the mandate period, as well as significant relaxation for ICE vans.
In its response to the ZEV mandate consultation, BEAMA supported a firm and progressive trajectory towards full electrification. This response called for limited allowance to plug-in hybrid electric vehicles (PHEVs) only and not to include HEVs as a transitional step.

£600m investment into skilled construction workers welcomed
Chancellor Rachel Reeves has announced an investment of £600 million into the construction sector to help train 60,000 skilled personnel by 2029. The JIB welcomes this investment in training.
The Chancellor acknowledged that a lack of skilled workers is a major barrier to the government’s pledge to ‘get Britain building again’, as thousands of job vacancies remain unfilled.
Through funding and reforms, the government aims to pay for training places, ensure a sustainable flow of skilled construction workers and help businesses invest in skills. Plans include £165m to deliver more construction courses and £100m to set up 10 new Technical Excellence
Colleges. Foundation apprenticeships will be backed with £40m from the overall funding with employers receiving £2,000 for every foundation apprentice they employ and retain.
In addition, Skills Bootcamps will be expanded. In the electrical sector this funding is currently available for Qualified Electricians – who already hold an ECS Gold card – to upskill in areas such as low carbon technologies.
The JIB will continue to collaborate with organisations and stakeholders to ensure industry standards remain strong and are not in any way diminished by ‘fast-track’ routes.

Major carbon capture project to deliver jobs and growth
British families and businesses will be more energy secure as a major carbon capture and storage network is now ready for construction – supporting 2,000 jobs through the Plan for Change.
Energy company Eni have finalised a major deal with government, which will see them award around £2 billion in supply chain contracts for their Liverpool Bay Carbon Capture and Storage (CCS) project, spanning North Wales and the North West of England.
The deal delivers on a commitment
made by the Prime Minister and Energy Secretary in October to develop a world leading carbon capture industry – backed by £21.7 billion – reigniting industrial heartlands across the country and kickstarting growth in manufacturing communities.
This announcement comes as the North Sea Transition Authority (NSTA) awards three carbon storage permits to Eni for its Liverpool Bay CCS project. It will create a network of clean infrastructure, decarbonising industries like energy from waste,
Record-breaking start to year for small-scale renewables
Commenting on the latest MCS data, Ian Rippin, CEO at MCS, said, “The latest data from the MCS Data Dashboard shows that March was the best month of 2025 so far, totalling more than 31,000 certified installations – up 49% from March 2024.
“Heat pump uptake continues to rise, with 5,604 certified installations – a 22% increase on March of last year. Solar PV also had a strong month, with a total of 22,599 installations in March. This was a 49% increase on March 2024. This means that there are now over 1.7 million MCS certified solar PV installations.
“March was another record-breaking month for battery storage, with almost 3,000 certified installations, beating the previous record set in February and a 147% increase on March 2024. This brings the total battery storage installations to over 33,000.”

ECA calls for urgent reform of electricity levies
ECA, along with 35 organisations from the energy sector, have written an open letter to the Secretary of State, Ed Miliband, calling for urgent reform of electricity levies.
The number one recommendation of the independent Climate Change Committee’s Seventh Carbon Budget is to make electricity cheaper by removing policy costs. The joint letter supports this position, while pointing out the importance of electrification to the UK energy security and independence in an unstable world.
The letter said, “Even if climate change was not happening, it would still be right to electrify. Our dependence on gas imports exposes every household with a gas boiler, and the entire economy, to the erratic international gas markets the UK cannot influence.”

Opposition to ‘Sunshine Bill’ won’t slow down solar momentum
The New Homes (Solar Generation) Bill recently had its second reading in the House of Commons. However, due to government opposition, it failed to go any further. While opposition of the bill may seem like somewhat of a step backwards, Lee Sutton, Co-Founder and Chief Innovation Officer of myenergi, believes that the decision will do little to slow down the monumental rise of microgeneration. Here, he explains why the UK’s adoption of solar power will continue to boom, regardless of mandatory installations on new build properties.
OLee Sutton Co-Founder and Chief Innovation Officer of myenergi
ver the past few years, solar adoption rates have hit record levels. Indeed, according to the Microgeneration Certification Scheme (MCS), an impressive 220,000 systems were fitted last year alone, more than any other year. As a result, panels are now said to be installed on the roofs of more than 1.4 million UK homes.
It feels as though the rise of renewables has come out of nowhere. But if you take a step back, it’s not hard to understand why. A volatile energy market, fluctuating costs, price caps creeping upwards and threats over blackouts have put the general public on red alert. This, combined with increasing consumer awareness about the environmental impact of fossil fuels, has led millions of householders to look towards cleaner, greener, cheaper solutions.
Commonplace in properties
Domestic-scale renewable energy generation technologies, like solar PV and heat pumps, are quickly becoming commonplace in properties nationwide. While previously considered a novel and
often expensive solution, continued research, development and economies of scale have seen prices crumble.
As a result, insight from Which? suggests that you can now purchase and install a 3.5kWp solar array for around £5,500. On its own, solar PV can cut bills significantly. By adding a home battery – like the myenergi libbi – to store power in periods of high generation and deploy it in periods of low generation, you can see these figures fall even further.
Maximising self-consumption
What’s more, the industry’s rapid growth has also given rise to a new dawn of technologies, such as power diverters, designed to maximise

self-consumption. Much like batteries, these devices aim to tackle issues surrounding intermittent generation. At myenergi, we’re renowned for designing and manufacturing an integrated ecosystem of solutions to optimise energy use in the home. Alongside our eddi power diverter, we brought the world’s first solar-compatible electric vehicle charger – zappi –to market.
By combining self-generation with innovative solutions to optimise self-consumption, it’s possible to minimise your reliance on the grid, reduce your carbon footprint and save thousands of pounds on your energy bills. All in all, it’s a sensible decision – with householders switching to renewables in their droves.
So, while the New Homes (Solar Generation) Bill failing to garner government support is disappointing, it’s unlikely to slow down renewable energy momentum. The benefits
“With changes to Part L of the Building Regulations coming into force next year, renewable energy self-generation remains a highly attractive proposition.”
of self-generation will continue to attract consumers and the transition will continue at pace.
Changes to the Building Regulations
Interestingly, when it comes to new build properties, it’s unlikely to make too much of a difference either. After all, with changes to Part L of the Building Regulations coming into force
Had the New Homes (Solar Generation) Bill have been passed, the move would have seen all homes built after 2026 fitted with mandatory solar panels – a significant step forward in future-proofing new properties and one that would increase their energy efficiency, minimise carbon emissions and accelerate progress towards 2050 net zero emissions targets.
next year, which will require property developers to incorporate state-of-theart energy-saving technologies into their projects, renewable energy self-generation remains a highly attractive proposition.
Housebuilders can use any technology that they choose, but solar PV and battery storage remains one of the easiest, most cost-effective, readily available decarbonisation solutions on the market.
So, as an industry, let’s not be spooked by government opposition to the New Homes (Solar Generation) Bill. The roll-out of renewables is happening at pace and, while legislation is critical to accelerate progress, we’re likely to see far more impact through changes to Part L of the Building Regulations.

EESS: protection against electric shock
Correctly identifying the method of protection against electric shock when using an electrical energy storage system (EESS) is crucial to maintaining safety and compliance – what do I need to know?
ENeed some technical advice?
Darren is here to help! Send your questions to: info@electrotechnicalnews.com
lectrical energy storage systems (EESS), such as battery storage solutions, are increasingly used to enhance energy efficiency, provide backup power, and integrate with renewable energy sources. However, ensuring the correct method of protection against electric shock is crucial to maintaining safety and compliance with electrical safety standards/regulations.
Incorrect identification or improper implementation of protective measures can lead to significant electrical dangers, including the risk of electric shock due to the failure of automatic
disconnection of supply (ADS) in the event of a fault.
Understanding the method of protection against electric shock
When using a supply from an EESS, the primary method of protection against electric shock must be correctly determined based on the system’s earthing arrangement and operating mode. The protective measures should align with BS 7671, which sets out specific requirements for electrical installations, including those involving energy storage. Further guidance can be found in the IET Code of Practice for Electrical Energy Storage Systems.
In a typical grid-supplied installation, earthing and ADS rely on a solid and continuous connection to the distribution network. However, when an EESS operates in island mode (i.e., when disconnected from the grid and supplying power independently), the standard earthing reference

point may be lost. This can compromise the protective measures designed to prevent electric shock, making it essential to establish a reliable means of maintaining earthing and ADS.
The role of a neutral-bond relay in ensuring safety
A neutral-bond relay (NBR) plays a critical role in maintaining electrical safety when an EESS is in operation, particularly in island mode. Its primary function is to create a defined earthing arrangement by bonding the neutral of the output supply to earth when the system is operating independently. This ensures that ADS functions correctly in the event of a fault.
Without an NBR, the system could operate with an undefined or floating neutral, leading to:
• Failure of ADS: Protective devices such as circuit breakers, RCDs and RCBOs may not detect faults correctly, increasing the risk of electric shock.
• High touch voltages: A floating system can result in hazardous voltages appearing on conductive parts, posing a significant risk.
“A neutralbond relay (NBR) plays a critical role in maintaining electrical safety when an EESS is in operation, particularly in island mode.”
• Non-compliance with regulations: BS 7671 requires a properly referenced earthing system for electrical safety.
Installing an NBR ensures that in the event of a fault, the protective devices disconnect the supply as intended, maintaining compliance and protecting individuals from electric shock.
Conclusion
Many of the EESS have an emergency power supply (EPS) output that will remain energised when a grid connection is lost via the stored energy within the batteries. In the instructions, some manufacturers recommend this EPS is only used to feed a single item of double insulated equipment. Using the EPS to supply a number of maintained final circuits is possible, but only once an NBR has been installed to ensure the protective devices will operate in the event of a fault, and to allow the designer and installer to use class 1 equipment and products when in islanding mode.
It is highly recommended that anyone wanting to offer a maintained supply from an EESS should ensure the system is capable of having this essential work carried out. Not all EESS have the ability to be changed easily.

Meet Stacey
Stacey Lucas is Commercial and Marketing Director at Sontay and has been working in the building controls and BEMS sector for over 20 years. Having started her career at Sontay in 2001 as a Customer Service Advisor, Stacey progressed through the ranks, gaining a high level of technical understanding of the building controls sector. She joined BCIA’s Management Committee in January 2022 and served as BCIA Vice-President from November 2022 until her appointment as President of BCIA in March 2024.
After the company she was working for went bust in 2001, Stacey spotted an ad for the Customer Service Advisor role at Sontay – a manufacturer of sensing and peripheral devices that are vital in any building controls application to provide essential data. Her application was successful and “the rest is history!” she says. Since then, Stacey has held a variety of roles at Sontay, progressing to managing the customer service team before moving into the sales department. “My interest in the more technical
Sit down with: BCIA President Stacey Lucas
Building energy management systems (BEMS) have a key role to play in the UK’s transition to net zero, with figures suggesting their implementation could save up to 60% of energy in a building. Electrotechnical News spoke to Stacey Lucas, Commercial and Marketing Director at Sontay and BCIA President, to find out more about the BCIA’s mission to highlight the importance of building controls and automation.
side of the company then saw me take up a role as manager of the technical support team before I was promoted to the senior management team and the board in 2012. At this point, I became the Commercial Manager. Two years later I became the Commercial Director, and two years after that I transitioned into the Commercial and Marketing Director role.”
Having worked in the building controls sector for 24 years, Stacey says the most significant change she has witnessed in that time is the move from analogue to IT-based systems. “There is still a long way to go but the advancements in technology and the adoption of such solutions have been substantial in the past two decades and don’t show any sign of slowing down,” she says.
“I have also gradually noticed an upturn in the number of people embracing technology and wanting to utilise smart building systems to help them cut carbon emissions and improve energy efficiency,” Stacey adds. “The sector has much work to do to increase this awareness and the adoption of technology further, but it has been encouraging so far.”
Indeed, the Climate Change Committee recently revealed that the implementation of building energy management systems (BEMS) could save up to 60% of energy in a building. “It shows the importance of BEMS
“The evertightening sustainability and energy efficiency standards will mean that BEMS become vitally important.”
in attempting to meet the ambitious net zero target of 2050,” Stacey says. “The ever-tightening sustainability and energy efficiency standards will mean that BEMS become vitally important and an ideal option for any building owner or property developer looking to reduce its carbon footprint and control the building’s energy consumption.”
The UK’s decarbonisation journey
An exciting time, then, to lead the Building Controls Industry Association (BCIA), the go-to trade association for the building controls and BEMS sector in the UK. Having been appointed BCIA President in March 2024, Stacey recently celebrated her first year in the role. In that time, the BCIA has
achieved a great number of things, she says, including substantial growth as an association, increasing apprenticeship opportunities, and reducing the skills gap, “but I think my proudest moment is the fact we’ve been able to lobby the government on some important things and really raised the agenda”.
Keen to represent its members in the best possible way, the BCIA regularly works alongside the government to help shape policy and drive awareness of the importance of BEMS in the UK’s decarbonisation journey. “We recently provided the government with our response to the Future Buildings Standard consultation and our feedback was taken into account and listened to more wholeheartedly than ever before,” Stacey says. “Close collaboration with governance and energy consultants enabled us to communicate our response in such a way that it would be listened to –meaning the government has taken on board the BCIA’s opinions on the
“The Climate Change Committee recently revealed that the implementation of BEMS could save up to 60% of energy in a building.”
regulations and the BEMS sector’s important role in the decarbonisation of the UK’s building stock.”
Additionally, the BCIA met with the non-domestic decarbonisation team at the Department for Energy Security and Net Zero (DESNZ) in
late 2024 to discuss how building controls could help the department achieve its policy objectives. Stacey says the association hopes to meet with other government departments – such as the Ministry of Housing, Communities and Local Government – as well as Mayoral Combined Authorities and think tanks to highlight how building controls and automation can be supported through the Building Regulations and the Future Buildings Standard.
The message is clear, she says: “It’s about highlighting just how much of a difference building controls and automation can make – not only to the amount of carbon emissions it can reduce but also the increased comfort for building occupants, and the amount of money that can be saved on energy expenditure. We want to help decision-makers understand just how much money hospitals, schools and other public buildings can save just by specifying and installing BEMS across their premises.”
Incredible career opportunities
The boom of building controls technology is not without its challenges though, with Stacey highlighting the skills gap as the biggest challenge facing the BEMS sector: “The sector is nowhere near getting to the level of people coming into the industry that it needs.”
She says it’s “absolutely imperative that the sector is made more attractive to young people”, and calls for awareness of the variety of “incredible career opportunities” to be increased in schools and other educational facilities. “There needs to be encouragement of any young people interested in STEM to further their knowledge and interest in these fascinating disciplines, as these will be key in advancing technology and addressing global sustainability challenges.”
Stacey believes there is also a general lack of understanding and awareness of the importance of BEMS and the vital role of the technology in reducing energy consumption and improving energy efficiency. “The sector is set to be crucial in helping the UK meet net zero targets,” she says, “meaning young people that begin careers in BEMS will have a thriving and interesting sector in which to work. So, it is imperative that the industry, the BCIA and
the government work together to increase this knowledge and understanding and educate those both inside and outside the industry on the importance of this sector.”
In addition to encouraging more young people to start careers in BEMS, Stacey highlights the importance of supporting those already in the industry to further their knowledge base and skills through ongoing training and development. “Education and ongoing development are absolutely key,” she says. “However, while there are a lot of qualifications out there, technology
is advancing all the time, so it’s more about staying abreast of those developments. “For those that have their ECS cards now, they will need to seek the most up-to-date training so that they’re not drifting in their knowledge of what’s out there.”
The future is bright
As she enters the second year of her BCIA Presidency, Stacey is looking forward to the BCIA Awards in May, as well as quantifying the association’s successes in the past 12 months. “The BCIA had an incredible 2024 and saw superb growth – and it’s looking like 2025 has great potential to exceed this.” As for the future of the building controls industry, “it’s exciting times!” she says. “With sustainability increasingly becoming a major aspect of building design and construction, and up to 60% of energy able to be saved by having BEMS installed, the future of the industry looks very bright.
“Technology is advancing all the time and more building owners and developers across the UK – especially owners of large commercial premises, such as hospitals, schools and public sector buildings – are looking to smart buildings as a way of reducing energy consumption and improving energy efficiency. So, you could say that the future of many commercial buildings across the UK is in the building controls industry’s hands.”

Anything to declare?
Phil Brown, Product & Marketing Director at NVC Lighting, explains why Environmental Product Declarations (EPDs) are becoming an essential part of the sustainability conversation and how they can help businesses navigate an evolving regulatory landscape.
APhil Brown Product & Marketing Director at NVC Lighting
s sustainability becomes a defining factor in the electrical industry, professionals are seeking clearer, more reliable ways to assess the environmental impact of their products.
Environmental Product Declarations (EPDs) have emerged as a trusted tool, offering third-party verified data that puts the power of informed decisionmaking into the hands of buyers.
What are EPDs and why do they matter?
EPDs provide a transparent, standardised way to assess a product’s environmental impact over its entire lifecycle – from raw material extraction to disposal. By
offering detailed, independently verified insights, they cut through misleading sustainability claims and allow specifiers, architects and project managers to make choices aligned with their environmental goals.
Sustainability is a complex and often shifting landscape. EPDs set a new benchmark for transparency in an industry where reliable information is crucial.
What to look for
If you’re new to EPDs, focusing on key sections can make it easier to interpret the data:
• General information: Includes details about the manufacturer, product name and scope of the assessment. This provides a quick overview for comparison.
• Product lifecycle information: Covers every stage of the product’s life, including sourcing, manufacturing, usage and disposal, helping to assess long-term sustainability.
• Environmental impact data: Breaks down measurable factors such as carbon footprint, resource consumption and emissions, offering a detailed understanding of environmental performance.
Are EPDs mandatory?
Currently, EPDs are voluntary, but their adoption is growing rapidly. As sustainability standards tighten, both public and private sector stakeholders are recognising the value of independently verified environmental data.
Without third-party verification, an EPD may not be recognised by major certification schemes, regulations or procurement frameworks.
Driving change
Forward-thinking manufacturers are already integrating EPDs into their product offerings, demonstrating a commitment to sustainability. At NVC Lighting, we’ve embraced EPDs as part of our dedication to transparency. Our EPD verified PROe range not only meets the highest performance and efficiency standards, but also provides customers with clear insights into the environmental footprint of each product.
As more companies adopt these declarations, the industry moves closer to a future where sustainability is measurable, comparable and truly transparent.

Know when to show your metal
Although there are a range of factors to consider when selecting appropriate cable management systems, it is advisable to start with the environment where it will be installed. Terry Adams, Technical Manager at Marshall-Tufflex, highlights why for some scenarios, metal systems are the right solution.
Terry Adams Technical Manager at Marshall-Tufflex
The environment should play a significant role in your decision-making process, as this will help you to assess the potential risk and exposure levels. Ensure you are up to date with regulation 522.6 of the IET Wiring Regulations 18th Edition (BS 7671) as this provides guidance on protecting cables from a range of
‘external influences’, such as impact, abrasion, penetration, tension and compression.
It states that in environments where medium or high severity impacts can occur, cables should be protected using one, or a combination of, the mechanical characteristics of the system, the installation location and additional protection such as a barrier to prevent any impacts.
Should the installation be in a commercial, industrial or retail environment, then the most suitable means of reducing the risk of any mechanical stress on cable installations and to prevent the risk of accidental damage is to use ceiling mounted metal cable trays and wire
baskets, which will route them out of the way.
Safety considerations
Once the overall environment has been addressed, safety considerations should extend to selecting non-fire propagating, low emission products, as well as earthing and bonding. This is another area where metal cable management solutions can be beneficial, as steel and aluminium are both classified as non-combustible, low smoke zero halogen (LS0H) materials. Just be mindful of accessories and fittings as well, and if you want to maintain the LS0H classification for the installation, opt for polycarbonate fittings.
The 18th Edition of the Wiring Regulations also includes enhanced requirements to minimise any risk of falling and fallen cables in the event of a fire, which could pose a serious hazard to occupants attempting to evacuate, and hinder safe and easy access through the building for fire fighters. The regulations state that all cables should be adequately supported using non-combustible fixings to prevent premature collapse in the event of a fire.
As such, electrical contractors should be looking for cable management solutions that have a melting point high enough to sufficiently withstand the heat of a fire – 1000oC for up to 120 minutes.
Up to standard
It is vital to be aware that although aluminium does have excellent resistance to heat, it does not meet
“Safety considerations should extend to selecting non-fire propagating, low emission products, as well as earthing
the required standard, and therefore is not acceptable as a sole form of support. If aluminium trunking or trays are used, cables must be fixed to the fabric of the building using fireresistant steel cable clips. Steel cable
management offers an even higher melting point than aluminium and, when connected to a fire-resistant element of the building’s fabric, it can effectively protect from the risk of fallen cables.
In addition, if you think there could be a risk of radiated electromagnetic interference (EMI) due to a large number of data, power and service cables being routed together, then the data and power cables need to be separated using a material that provides shielding. Both aluminium and steel are ideal solutions if you face a scenario that needs a robust approach to EMI protection.
If you do conclude that metal cable management is the best solution, there are different options to choose from, including metal trunking, metal trays and wire baskets. Threaded rod ladders, wire suspensions and metal strut frameworks can also all be considered as support for these systems.

Verification of earth fault loop impedance
Earth fault loop impedance testing is a common test undertaken every day all over the country. It is a staple of the electrical contracting industry. Most of the time the tests are simple to perform, and results are often easy to interpret. However, in some cases the measurements can be confusing, or give readings that seem to suggest the system is unsafe. Here, Curtis Jones, Technical Manager at ECA, provides some guidance about the methodology and interpretation of test results when undertaking earth fault loop impedance testing.
Curtis Jones Technical Manager at ECA
Key points to remember when performing the test and verifying the readings include the following:
• The method used may affect the accuracy of the reading.
• Test equipment with a low measurement range may be required when conducting tests near the origin of supplies or transformers.
• The temperature of conductors needs to be considered when verifying readings.
What is earth fault loop impedance?
The definition of ‘earth fault loop impedance’ can be found within part 2 of BS 7671 which states it is ‘the impedance of the earth fault current loop starting and ending at the point of earth fault. This impedance is denoted by the symbol Zs.’
Essentially, it’s the level of impedance within a circuit opposing the current generated during an earth fault condition.
The verification of earth fault loop impedance is crucial for each circuit within an installation to confirm automatic disconnection of supply (ADS) is achieved, when this is the protective measure provided against electric shock. Often this is achieved by the use of an overcurrent protective device. The device should disconnect the supply to the line

conductor of the circuit or the equipment in the event of an earth fault condition, within a specified time. Table 41.1 of BS 7671 indicates maximum disconnection times and should be applied for final circuits within the scope of Regulation 411.3.2.2.
The figures presented in Table 41.1 rely upon a suitably low earth fault loop impedance path within the circuit, allowing sufficient fault current generation. This in turn will cause the protective device to operate within the specified time.
Example of an earth fault loop path in a circuit
Table 41.1 – Maximum disconnection times from BS 7671
Methods of obtaining earth fault loop impedance values
There are two widely used methods for obtaining earth fault loop impedance values of a circuit:
1. The preferred method is often to perform a continuity test of R1 + R2 and then add the value obtained to the external earth fault loop impedance (Ze) where the circuit is fed from the origin of the installation, or the (Zdb) where the circuit is fed from a subdistribution board.
2. Direct measurement of total earth fault loop impedance (Zs) can be made with an earth fault loop impedance tester.
It is important to select test equipment suitable for the purpose of the test, with measurement ranges that meet the requirements of BS EN 61557-3:2022. Performing a direct measurement is particularly useful when working within an existing installation, for example when carrying out periodic inspection and testing or maintenance activities.
Inaccuracies when measuring earth fault loop impedance
Modern multifunctional test instruments usually offer three methods for performing direct measurements of earth fault loop impedance. These methods can present certain limitations when trying to obtain an accurate reading that need to be considered.
The two-wire ‘high current’ test setting should always be utilised when possible. This method generates a large enough test current (typically in the region of 25 A) to create a measurable voltage drop and therefore a stable and accurate reading. However, if, for example, a residual current device is present, then either a three-wire ‘non-trip’ test setting or a two-wire ‘non-trip’ test setting would need to be utilised. The two-wire ‘non-trip’ setting is the most technically difficult for the instrument to perform and therefore more prone to errors. For this reason, this method should only be used as a last resort, for example at a passive switch where no neutral is present. The difficulty with the ‘non-trip’ test settings is that the test current is significantly smaller than the two-wire ‘high current’ test setting (generally not exceeding 15 mA) in order to prevent the residual current device within the
circuit from tripping. Due to such a low level of current, the test does not create a significant voltage drop and readings are prone to a larger degree in variation.
Further factors such as external load switching, electrical noise, harmonics and other electronic components or devices will also create difficulties when obtaining a measurement. These factors can have a greater effect when using a ‘non-trip’ test method where they may further hinder the accuracy of the test results obtained. This emphasises the need to utilise the ‘high current’ test setting where possible.
Residual current devices (RCDs) can at times also present problems with test results if the internal impedance of the device itself is included. On occasion, this may be as high as an additional 0.5 Ω. Clearly there may be times when the addition of this number within the test result reading may indicate that the circuit doesn’t conform with the requirements of BS 7671.
This is commonly known as ‘RCD uplift’ and inspectors should be aware of this possibility, although it’s worth noting that this anomaly does not occur for all types of RCDs. If RCD uplift is suspected, then a simple measurement can be conducted on the supply side of the device and then repeated on the load side of the device to establish if additional impedance is observed. Some multifunctional test instruments are immune to the effects of RCD uplift and inspectors should consult manufacturers’ literature for their equipment.
Permissible measurement errors and effects on low impedance measurement accuracy
Measurements of earth fault loop impedance when close to a transformer or other large source of
supply can present difficulties to offthe-shelf test instruments because the values likely to be obtained may be below the measurement range for the instrument. In this case, a highresolution test instrument should be used to ensure more accurate and reliable test measurements.
It is worth remembering an enquiry may be made to the distributor to obtain external earth fault loop impedance and prospective fault current levels at the origin of an installation. For larger systems with a private dedicated supply, the organisation responsible for its commissioning may make these values available.
When establishing the suitability of an instrument to make reliable measurements, refer to the BS EN 61557 series for permissible values of measurement error for which test equipment should comply. For loop impedance testers, BS EN 61557-3:2022 allows for a permissible measurement error of up to 30%. When comparing this information with the manufacturer’s literature for the test equipment, the 30% permissible error looks quite large, and inspectors may initially believe their instrumentation is significantly more accurate than this requirement. However, there are a few terms we need to consider before an accurate assessment and verification of the test equipment can be established.
Common measurement terms
• Display range – the numerical value of the display. e.g. 2,000. Typically, a display will show values of 00.0019.99 Ω, 199.9 Ω or 1,999 Ω.
• Resolution – the smallest change in the measured value that the displayed range can show. For a 2,000 numerical value display this would typically be 0.01Ω. Permissible
• Measurement range – where the manufacturer states that the possible error is not greater than that specified in BS EN 61557-3. For example, 0.20 Ω to 1,999 Ω.
• Instrument accuracy – this is specified and made up of two values.
- Analog error: normally expressed as a percentage of the measured value.
- Digital error: shown as an additional digit error or digit measurement value. Accuracy is shown on a product datasheet as ±(% of m.V. + digit error).
For example, a typical multifunctional test instrument may have a numerical value display range of 0.00 Ω to 1,999 Ω for the earth fault loop impedance test setting. However, in reality, these types of instruments are likely to have a measurement range different to this. Measurement values below around 0.20 Ω in typical multifunction test instruments may be susceptible to significant errors and fall outside the 30% permissible measurement error range (see table above).
Manufacturers of test instruments are now required to provide information on the measurement range of the instrument, taking account of the permissible measurement error values. Previously, the information provided with such test instruments was often the numerical displayed value range, rather than the measurement range.
This information can be found within the manufacturer’s literature or may
be displayed on the instrument itself, and could typically be 0.30 Ω to 1000 Ω with a resolution of 0.01 Ω. This would still satisfy BS EN 61557-3:2022 when used within its parameters, but this equipment may not be suitable for use where measurements fall outside of the measurement range specified by the manufacturer (see table below).
High resolution earth fault loop impedance testers
Many larger installations have private substations and transformers supplying the premises. In these circumstances, values of impedance near the origin are likely to be very low, and protective devices such as BS EN 60947-2 moulded case circuit breakers (MCCBs) are often used. Where live testing is performed, suitable test equipment should be employed in order to verify adequate disconnection of such devices. It
would be wrong to assume a circuit fails to meet its disconnection time, if maximum values of impedance aren’t met, if the values fall outside the instrument’s measurement range taking into account the permissible measurement error values.
For such circumstances, a suitable high resolution earth fault loop impedance test instrument should be selected when performing tests. These types of instruments typically have increased measurement resolution of 0.1 mΩ and have a measurement range reading as low as 7.2 mΩ, whilst providing a test current in the order of 130 A to 300 A (see table above).
The increased measurement range and instrument resolution enables more accurate readings to be
Example of a measurement range with 0.01 Ω resolution with an accuracy/error of ±(2% m.V. + 4 digits)
Example of user guide display and measurement range tolerances for a multifunction tester (Sonel MPI-540)
Example of a measurement range with 0.1 mΩ resolution with an accuracy/error of ±(2% m.V. + 2 mΩ digits)
obtained and thus the inspector can verify if the requirements of automatic disconnection are being satisfied. Inspectors should always consult manufacturers’ literature to confirm that test instruments are used within the parameters for which they were designed.
Maximum acceptable values of earth fault loop impedance
Values of earth fault loop impedance obtained should preferably be verified against maximum values stipulated by the manufacturer of the protective device, which are often less onerous than the values detailed within BS 7671. This information should be noted on the schedule of circuit details and schedule of test results when completing required documentation.
In the absence of manufacturers’ data, BS 7671 provides maximum earth fault loop impedance values for common fuses and circuit breakers. However, these values are based on the line conductors being at their maximum permitted operating temperature, and circuit protective conductors being at their assumed initial temperature when the measurement of impedance was obtained. For measurements made at ambient temperatures, Appendix 3 of BS 7671 provides
guidance, and adjusted values for typical circumstances can be found within the IET’s Guidance Note 3 or the IET’s On-Site Guide. These are often known as the ‘80% Values’.
Many inspectors apply a blanket approach to verifying Zs values against the values that have been adjusted for ambient temperature. However, in some instances this may be difficult to achieve due to the circuit constraints. For example, during periodic inspection and testing a load may have been momentarily shut down to allow a test to be performed. As a result, the circuit conductors will likely still be considerably warmer than that of ambient temperature in a vicinity. The circuit may also be installed within shared containment systems such as trunking, where other adjacent circuits operating under load conditions may cause heating effects for the circuit under test. As can be seen, verifying Zs values obtained often involves applying sound engineering logic in order to confirm compliance with BS 7671.
Summary
Earth fault loop impedance testing, when done well, is a simple and easy method to verify the safety of circuits.
In some cases, off-the-shelf test equipment may not always be accurate or specific enough to measure, with any degree of certainty, the earth fault loop impedance of the circuit.
It is therefore vital that not only should you have the correct competence of people using the equipment, but the equipment itself should be suitable for the function it is performing.
A simple off-the-shelf multifunction piece of test equipment will normally suffice for most projects, but on occasion specialised equipment may be needed.

Enhancing indoor air quality
Condensation, dampness, mould and poor indoor air quality (IAQ) are common year-round issues in homes, often stemming from inadequate ventilation. Electrical professionals can help tackle these issues by installing advanced IAQ technologies and guiding customers on the long-term benefits of these solutions, says Lee Stones, Senior Category Manager – Ventilation at Xpelair by Dimplex. Here, Lee explores the importance of maintaining optimal IAQ and showcases positive input ventilation (PIV) systems as an effective solution for creating healthier living spaces.
Lee Stones Senior Category Manager –Ventilation at Xpelair by Dimplex
Indoor air quality (IAQ) is a growing concern, particularly as airtight building designs become more common. Public Health England warns that poor IAQ can contribute to respiratory infections, heart disease and even lung cancer. A BEAMA survey found
that 65% of UK homes experience indoor air pollution, with indoor air containing up to 50 times more pollutants than outdoor air. Mould is another widespread issue, with data from the Warm This Winter campaign revealing that 29% of UK residents frequently or occasionally experience mould in their homes. The COVID-19 pandemic further underscores the need for adequate ventilation systems to reduce airborne pathogen transmission.
Maintaining clean air has never been more critical, as people spend most of their time indoors. As such, the industry continues to develop
“65% of UK homes experience indoor air pollution, with indoor air containing up to 50 times more pollutants than outdoor air.”
energy-efficient ventilation systems that enhance IAQ, focusing on energy-efficient and environmentally sustainable solutions which also operate quietly.
PIV systems
One high-performance solution is positive input ventilation (PIV). These systems provide controlled, efficient mechanical ventilation to reduce excess humidity, which is a primary cause of condensation and mould growth, without compromising a property’s energy efficiency.
PIV systems are straightforward to install in most properties. They draw in fresh external air, filter pollutants and allergens, and introduce clean air into the home through a ceiling diffuser. This creates a gentle, positive air pressure that pushes stale, moist air out through natural escape points such as trickle vents and door gaps, reducing humidity levels and improving air quality.
Many PIV units include heating elements to temper incoming air during colder months, ensuring comfort year-round. They operate automatically with minimal user interaction, are designed to be lowmaintenance, and offer a ‘set and forget’ solution. Their quiet operation and unobtrusive design make them a seamless addition to homes, and with low power consumption, they provide an energy-efficient approach to tackling IAQ challenges.
Healthier indoor environments
A leading solution is Xpelair’s Everdri, a PIV system designed for houses with loft spaces. Installed centrally on the landing or in a hallway, the Everdri transforms stale, stagnant air into a fresh, healthy, condensation-free environment.
The Everdri PIV unit reduces surface condensation and mould, improving overall air quality. It also significantly lowers radon levels
Andrew Moseley, Commercial Director, City Electrical Factors (CEF)
“Dimplex’s focus on indoor air quality and positive input ventilation (PIV) solutions aligns with CEF’s commitment to offering products that create comfortable, more energy-efficient homes. PIV systems play a vital role in tackling condensation, mould and poor ventilation, helping to create healthier living spaces. CEF recognises the increasing demand for these solutions and provides an extensive range of Dimplex products that improve indoor air quality.”

by gently introducing fresh, filtered air and expelling contaminated air. Everdri redistributes warmer air from ceiling level, which can be up to 7˚C higher than ground level, potentially reducing heating costs. For ease of use and maintenance, it includes an easily replaceable, long-lasting, washable G4 filter to capture dust, pollen and other airborne particles.
The Everdri XELH model offers extra features to ensure comfortable temperatures and prevent cold draughts during colder months. These include a pre-heater that tempers the incoming air and a temperature probe that monitors air conditions. This enables the system to adjust airflow for optimal energy efficiency.
Embracing high-performance ventilation systems improves living conditions and supports healthier, more energy-efficient buildings, contributing to a more sustainable future. By offering PIV systems, installers can deliver a modern solution that meets growing demands for healthier, energy-efficient indoor environments while creating a professional point of difference and expertise in a competitive market.

Awaab’s Law: what you need to know
The government has confirmed that Awaab’s Law is set to be implemented in the social housing sector in October 2025. Although many social housing providers have already brought in measures to combat condensation and mould to prepare for Awaab’s Law, there is still a significant damp and mould problem in social housing. Katie Mairs, Channel Marketing Manager at Vent-Axia, explains how the electrical sector can help.
Tackling damp and mould has become an important issue for the electrical sector, and Awaab’s Law has brought the risks of living in a mouldy home into sharp focus. The law was initiated following the tragic death of two-yearold Awaab Ishak, due to a mouldy home. Awaab’s Law is part of the Social Housing (Regulation) Act and is set to impose strict requirements on social housing landlords to investigate and resolve issues of damp and mould within specified timeframes, helping residents gain faster repairs and reducing health risks. It marks the biggest change in social housing rules in a decade, aiming to prevent future tragedies and improve tenant safety. With Awaab’s Law being implemented
in October, electrical contractors should be aware of the risks associated with damp and mould and how to overcome them.
From October 2025 social landlords will be required to address damp and mould hazards that present a significant risk of harm to tenants, within fixed timescales. From the same point in time, they will also have to address all emergency repairs, whether they relate to damp and mould or any other hazard, as soon as possible and within no longer than 24 hours.
The impact on social landlords is clear, but what does this mean for electricians? The answer is simple: indoor air quality (IAQ) and ventilation
will be in the spotlight – and so will those who install and maintain ventilation. Electrical contractors working with social housing customers should be aware of these changes due to the ongoing problem with damp and mould in the social sector.
English Housing Survey
The English Housing Survey recently revealed that 5% of dwellings in England had a problem with damp in 2023, higher than in any of the last five years (3-4%). But serious condensation was more prevalent in homes (3%) than rising damp (2%) and penetrating damp (2%). Within the social rented sector, local authority dwellings were more likely to have serious condensation (7%) than housing association dwellings (4%).

The data reveals that there is still a significant damp and mould problem in social housing in the UK which needs to be solved.
Under the Homes (Fitness for Human Habitation) Act 2018 landlords already have a legal requirement to provide rental properties that are fit for human habitation, including the need for effective ventilation and freedom from damp and mould.
Landlords need to meet their duty of care and tackle damp and mould by installing the right ventilation solution for each property. There are different types of ventilation available depending on the property type and whether there is already a mould problem. For example, the Heat Recovery Retrofit Solution has been specifically designed for easy, lower cost retrofit of heat recovery to save maximum energy and emissions and comply with the requirements of PAS 2035 in the social housing sector. The
Heat Recovery Retrofit Solution range consists of three different mechanical ventilation with heat recovery (MVHR) units, which can be used together to help improve IAQ and maximise energy savings by introducing heat recovery to the property.
Alternatively, another ventilation option for landlords is a filterless unitary fan, such as the intelligent Lo-Carbon Revive 7, which features an adjustable trickle speed option, an interchangeable intermittent mode and humidity boost, as well as a raft of useful original features to provide powerful, quiet and efficient ventilation.
For properties with hard-to-treat mould, landlords can opt for positive input ventilation — the Lo-Carbon PoziDry Pro and Lo-Carbon PoziDry Compact Pro are the ideal solutions. Designed to improve IAQ and prevent moisture build-up within social housing properties, the PoziDry range provides a highly effective solution to help households and landlords control condensation and mould, as well as offering high levels of air filtration.
Navigating the changes
For electrical contractors wanting to find out more about Awaab’s Law and how to tackle damp and mould, Vent-Axia has published a free e-book, ‘Ensuring Safe Housing Conditions: Focusing on Mould and Damp Conditions’. Aimed at social housing landlords, the publication gives guidance on Awaab’s Law to help landlords navigate the changes, tackle damp and mould, and create healthier homes for residents.
“Indoor air quality (IAQ) and ventilation will be in the spotlight – and so will those who install and maintain ventilation.”
Written by Vent-Axia’s social housing experts, the e-book clearly explains what Awaab’s Law is, why it matters, and how to comply. Providing a wealth of information, the document also outlines tenants’ rights and protection, other legal standards, and provides links to additional resources. Crucially, the e-book covers practical advice and insights on the health risks of damp and mould, and how to take proactive measures to prevent and tackle this twin blight. In addition, there is a useful ventilation checklist, and details of the different types of ventilation available, with guidance on choosing the right solution for a property.

This launch marks the start of a big year for Europa, which plans to introduce 15 new products in 2025 spanning both digital and physical electrical components.
Benefits of the Parrot system include:
• Saving money and time on installation
• Easy retrofitting
• No invasive works due to no cables
• Quick and simple installation
• No need to run cables or dig trenches
The system can be used for anything from remote gate controls, spotlights and switch gear, to measuring wind speed, temperature and pressure.
Rob Aitken, Technical Director at Europa, said: “The Parrot system leverages decades of accumulated knowledge and specialised expertise in industrial monitoring, control, and wireless communication. This suite of innovative wireless cable replacement devices is designed to streamline deployments by removing the need for expensive cabling or adding telemetry in places where it wasn’t previously possible.
“Parrot aligns perfectly with our mission to simplify and modernise industrial control solutions.”
Founded in 1974 and based in Luton, Europa has over 50 years of continuous growth. As a trusted name in the electrical industry, Europa provides a wide range of components and value-added services, including smart technologies, renewable solutions, and custom design and build.
Heat pumps provide sustainable solution for prestigious development
Ideal Heating has designed a sustainable heating system and is supplying heat pumps for a luxury residential development in the North East.
Ieal Heating’s Logic Air heat pumps will be used throughout the exclusive Stoney Wood development at Wynyard Village in County Durham, marking a significant vote of confidence in Ideal’s sustainable heating technology from one of the region’s most prominent developers.
The development of 76 homes will feature a mix of premium three, four and five-bedroom properties and is being delivered by Cameron Hall Homes. It’s the latest venture from entrepreneur Sir John Hall’s Cameron Hall Group, known for landmark projects including the Metrocentre retail and leisure destination in Gateshead and the revival of Newcastle United Football Club.
Notable ex-residents of Wynyard Village include football stars Alan Shearer and Kevin Keegan, as well as business tycoon Duncan Bannatyne. House prices on the Stoney Wood development range from £449,995 to £949,995.
Exceptional energy efficiency
Jamie Hooton, Head of Sales at Cameron Hall Homes, said, “Futureproofing our homes with reliable and sustainable heating technology was a key focus for us when designing the Stoney Wood development.
“We wanted to ensure our properties meet the needs of the modern homeowner while also aligning with long-term environmental goals.
Ideal Heating’s Logic Air heat pumps were the best choice, offering both exceptional energy efficiency and the robust support that gives both us and our customers complete peace of mind.”
Designed for the UK
The project represents another significant endorsement of Ideal’s heat pumps, with the company’s products now showcased in one of the region’s most prestigious residential developments.
Mark Cordingley, Key Account Executive – North East for Ideal
“We wanted to ensure our properties meet the needs of the modern homeowner while also aligning with long-term environmental goals.”
Heating, said, “We’re proud to partner with Cameron Hall Homes on this exceptional development, showcasing how our Logic Air heat pumps meet the needs of housebuilders creating modern, sustainable homes.
“Our heat pumps are designed and built specifically for the UK, ensuring they perform efficiently, even in our variable climate.
“At Ideal Heating, we’re committed to supporting installers, their customers – such as new-build developers –and, ultimately, homeowners. That’s why we offer free, in-person support for first installs from our expert heat pump team and provide a dedicated UK-based heat pump support service with live technical help.
“These services, combined with our industry-leading warranty and a 90% first-time fix success rate, mean customers can have complete confidence in choosing our heat pumps for their homes.”
Easy installation
JD Winter Plumbing, which is currently working on almost 50 sites across the North East, is delivering the installation programme.
Managing Director James Winter praised the benefits of the Logic Air system: “There are lots of reasons why you would choose a Logic Air heat pump. The range of pre-plumbed cylinders makes installation very easy and the outside unit doesn’t require a massive footprint, which is great because you don’t want to take up a lot of space with your heating system.
“We’ve had a really cold winter, but
we’ve had no complaints about the heat that they provide, which is even more impressive when you consider how big these houses are.
“The aftercare from Ideal Heating has also been exceptional – if we’ve had any issues, they’ve been sorted the next day.”
Exclusive community
The Stoney Wood development continues Sir John Hall’s longstanding connection with Wynyard Village, which he purchased from the Marquesses of Londonderry in the
1980s. The estate was transformed under his vision, inspired by high-end American developments, to create an exclusive community featuring golf courses and country walks in the beautiful countryside surrounding historic Wynyard Hall.
For Ideal Heating, it adds another successful project to the company’s ever-growing heat pump portfolio.
