NG Bailey net zero target validated by leading environmental body

NG Bailey has become one of the first construction and engineering companies in the UK to have its long-term target to achieve net zero emissions by 2045, approved by the Science Based Targets Initiative (SBTI).

The UK’s largest independent engineering and services business has set a target to achieve net zero by 2045 for its scope 1, 2 and 3 greenhouse gas emissions. As part of its long-term target, NG Bailey has committed to reduce greenhouse gas emissions for sources it owns or controls directly (Scope 1 and 2) by 90 per cent, as well as reducing emissions from its wider supply chain (Scope 3) by 90 per cent by 2045. The new target is in addition to its existing near-term targets, approved in 2022, which include a commitment to reduce absolute Scope 1 and Scope 2 greenhouse gas emissions by 50 per cent by 2031, and that 75 per cent of its suppliers will have science-based targets in place themselves by FY2027.

As well as setting future targets, NG Bailey has already taken significant steps to reduce its own emissions as part of its Net Positive responsibility strategy. All the electricity at sites where NG Bailey has operational control are now from renewable sources. It is phasing out diesel and petrol cars within its fleet by 2025, with 91 per cent of its company car fleet now battery or electric plug-in hybrid. It is also undertaking a trial of electric vans within its fleet and looking to the future and what alternative fuel solutions may be available.

Meet the sponsor

Kevin Gutteridge, Director of Trimble Luckins, speaks to ET about his career, the industry, and LUCKINSlive becoming the main sponsor of the Electrical Industry Awards 2024

Tell me more about your role…

In 1988, I joined Luckins as a developer in a newly formed department to look at these exciting things called ‘PCs’. Luckins was already a wellestablished data provider to the electrical industry and so I joined the business to develop a software offering around the data. Today, I run Trimble Luckins in the UK.

How has the company and the industry changed since you started?

The Luckins that I joined was predominantly a book publishing company that was in the early stages of producing data feeds. Today, we’re a data company that serves MEP wholesalers and contractors with feeds of product and pricing information and we offer manufacturers a valuable route-to-market.

The pace of change around data provision has massively changed over those 36 years; We’ve gone from a weekly printed publication delivered by post, to the Luckins of today which has direct connections plugged into wholesaler ERP systems and a much wider range of contractor software. Price fl uctuations have accelerated massively, and that keeps us very busy because we need to ensure they’re in the various systems before

the price effective date, but also the size of the databases has gone up exponentially. What was 20,000 items in 1988 is now over 1.2 million items and it’s our job to ensure that it is accurate and up-to-date for our consumers.”

What’s the biggest trends in the electrical industry at the moment?

When discussing the trends impacting the market, we identify three main themes. First is connectivity; at Trimble Luckins, we believe there is still a signiﬁ cant role for traditional wholesalers. Our manufacturer customers remain committed to the wholesaling chain rather than selling directly. However, we envision a

more connected future, where orders are placed directly with wholesalers through the end-user’s preferred software, such as estimating systems, procurement platforms, or maintenance and operations software, rather than through manual processes.

Second is renewables. We have witnessed a remarkable increase in the number of renewable energy products entering the market, and we expect listings of these products to continue growing. Consumers increasingly demand greater visibility of sustainability data.

Lastly, we are seeing a rise in multi-skilled contractors. While the Luckins database has primarily featured electrical products, we are now encountering more complex products that require expertise in multiple disciplines for installation. For example, water heaters often involve both electrical and mechanical elements. Larger contractors have long been multi-disciplined, and this trend is now extending to mid-sized and smaller companies. We must adapt to ensure the information we provide remains valuable and accessible to as broad an audience as possible.

Why did LUCKINSlive become the main sponsor of the Electrical Industry Awards?

At Trimble Luckins, doing the right thing for the electrical industry is paramount. We celebrate best practice and want to promote innovations that are going to move the industry forward. It seemed like a natural opportunity to collaborate with the Electrical Times and spend some time recognising those in the industry with a similar mission.

Why do you think Awards like this are important? Sharing expertise and experience is so valuable for everyone in the electrical industry - these forums for recognising achievement help to raise the bar and keep the industry pushing boundaries - plus an element of competition is always fun.

What’s next for Luckins?

We are advancing towards a digitally connected future. To enable our customers to access the vast amounts of data we process, our cloudbased solutions now provide data on demand, streamlining the integration process and removing the necessity for local data storage. Simply put, the data remains centralised and can be accessed by connecting various applications. We continue to focus on the entire supply chain with our collaborative approach to ensure optimal information flow throughout the industry.

This Code of Practice looks at electrical energy storage systems applications and provides information for practitioners to safely and eﬀectively specify, design, install, commission, operate and maintain a system.

Changes in this edition include:

– an update to the requirements for island mode isolators

– further guidance on the safety and the location of batteries within an installation

– updates to schematics for domestic use

– update to the requirements for sizing of generator connecting circuits, and coordination of assemblies through which generators connect

How tradesmen are reshaping the SME landscape

By Chris Sadler, Founder of Kimble Solar

In today’s changing market, tradesmen have a unique opportunity to upskill and adapt, enabling them to grow and strengthen their own businesses. By embracing new skills and staying ahead of industry trends, they can shape a more successful future for themselves and their businesses.

As a business owner myself, I’ve witnessed ﬁrsthand how the landscape is evolving for tradespeople, particularly electricians, and how we can leverage these changes to shape a brighter future for our businesses.

The power of visibility

Social media has dramatically shifted how we operate in the trade. It’s no longer just about who you know or what you know; it’s about who knows you. The importance of being seen and recognised is so crucial. Gone are the days of relying on Yellow Pages or word-of-mouth alone. Today, if you’re not visible online, you’re almost invisible to potential clients and other business opportunities.

For tradesmen, this is a doubleedged sword. We spend countless hours honing our craft, attending courses, gaining qualiﬁcations, and staying up to date with industry standards, but while we are excellent at our trade, many of us have little to no experience in marketing ourselves or growing our businesses. It’s not uncommon for tradespeople to lack business acumen because, traditionally, we weren’t expected to need it.

The importance of training

What’s often missing in the typical tradesperson’s career is formal business training. We invest heavily on improving our trade skills and knowledge - whether it’s learning about the latest electrical regulations or how to install cutting-edge solar systems - but we rarely invest in learning how to run a successful business. For those who want to scale, understanding the business side of things is just as essential as technical expertise.

When I started Kimble Solar, I faced similar challenges. Like many in the trade, I had all the technical skills but lacked the business knowledge to take things to the next level. I quickly realised that if I wanted to grow my business, I needed to learn how to market the business, ﬁnd clients, and manage a team. This is a hurdle that many tradespeople face

As a business owner myself, I’ve witnessed ﬁrsthand how the landscape is evolving for tradespeople, particularly electricians, and how we can leverage these changes to shape a brighter future for our businesses.

when they transition from being on the tools to running a business.

The freelancer dilemma

In the electrical trade, it’s common to go freelance, working on various contracts for larger firms. The flexibility this provides is appealing, but without marketing yourself, you’re at the mercy of the companies you subcontract for. Many tradespeople, including electricians, often undercharge for their services because of fear of pricing themselves out of the market or being seen as too expensive. Yet, the reality is that underpricing devalues not only your services but the entire profession. As electricians, we undergo rigorous training and certification processes, such as NICEIC registration, which allows us as business owners to bid for larger contracts. This level of skill and expertise justifies charging appropriately for the value we bring to each project.

Outsourcing: A key to growth

One of the most valuable lessons I’ve learnt is the power of outsourcing. As tradespeople, we tend to try and do everything ourselves, whether it’s the project itself, accounting, marketing, or even customer service. But at a

certain point, you have to admit that your time is better spent focusing on what you’re good at and where your time needs to be on growing your business.

Outsourcing areas like bookkeeping, social media management, or even lead generation can be a game-changer. Employing or outsourcing tasks to specialists far outweighs the costs in the long run. It allows you to focus on the growth of your business rather than getting bogged down by tasks that others could do more efﬁciently.

At Kimble Solar, we embraced this approach early on. Instead of spreading myself thin by trying to handle everything, I brought in experts who could help with marketing and operations. This allowed me to concentrate on expanding our service offerings and providing top-tier customer service.

Building a network for success

The trade industry is built on community, but often, we find ourselves in environments where the conversations are more about surviving than thriving. It’s typical to hear tradespeople complain about competition or discuss how difficult it is to make a profit without undercutting themselves. While this camaraderie is important, it can sometimes hold us back from seeing the bigger picture: that with the right business acumen, the potential for growth is enormous.

One way to break out of this cycle is to actively seek business networks outside your trade. Whether it’s joining a local chamber of commerce, attending industry conferences, or connecting with other SMEs, broadening your horizons can open doors to new opportunities. The more you surround yourself with business-minded individuals, the more you start to think like a business owner rather than just a tradesperson.

The role of tradespeople in SMEs is more signiﬁcant than ever. We’re not just the backbone of the economy; we’re reshaping how small businesses operate. By investing in your business, we can ensure that tradespeople remain a driving force in the SME landscape. The future is bright for those of us willing to evolve with the times, and with the right tools and mindset, there’s no limit as to what we can achieve.

Why safety must be prioritised in UK apprenticeship training

ABy Chris Claydon, chief Executive of JTL Training, a leading

charity organisation offering apprenticeships, assessment services and professional development training across the electro-technical and mechanical engineering services sectors in England and Wales

pprenticeships are the foundation of the skilled workforce in construction and building services.

Indeed the apprenticeship route is rightly recognised as the gold standard for electricians; the evidence shows that non-apprenticeship qualifications very rarely progress to a career in the industry. So, the quality of these programmes directly impacts the safety and sustainability of the buildings they help to create.

Recent electrical incidents in homes and large flat complexes have put the importance of safety in construction into the spotlight, reinforcing what many in the industry have long known: safety in building development is paramount. While it is promising to see the new Government promoting apprenticeships as a valuable education pathway, more must be done to ensure that all programmes meet the highest standards. It’s not just about increasing the overall number of apprentices; it’s about ensuring they receive top-quality training where safety is prioritised from day one.

While the Government has set ambitious targets to increase homebuilding, looking to build 1.5 million more homes in the next five years, there is a shortage of qualified electricians, plumbers, and other skilled tradespeople who are critical to delivering safe, energy-efficient homes fit for the future. It is our collective responsibility to ensure that the people building and servicing these homes are Fully Qualified and that safety is at the heart of their training.

At the same time, the drive to achieve net-zero carbon emissions by 2050 has added another layer of complexity. The skills required for modern homebuilding have evolved, incorporating new technologies and sustainability practices. This means the workforce needs to be equipped not only with traditional trade skills but also with expertise in green technologies such as solar panels, energyefficient systems, and smart home installations.

At JTL, we work with over 3,800 businesses and train around 8,000 apprentices in electrical engineering and plumbing. These are high-risk, safety-critical occupations and JTL Training is

committed to delivering high-quality training where the learner is placed at the centre, adapting to emerging technologies and cultivating a workforce that not only contributes to closing the widening skills gap, but also anticipates and fulfils the future demands of the dynamic wider industry.

Our training programmes are designed to equip apprentices with the skills they need to excel in their fields while ensuring safety is embedded in every aspect of their work. For example, we ensure our gas engineering apprentices go through rigorous training to develop the skills, knowledge, and behaviours needed to install, commission, decommission, and service and repair appliances in either a domestic or non-domestic setting. Our Level 3 Electrotechnical Apprenticeship has been recognised as a ‘gold standard’ programme and awarded the Coronation Emblem for its contribution to a low-carbon economy; preparing apprentices with future-proof skills while prioritising safety and sustainability.

With many experienced trade occupations in the built environment sector nearing retirement faster than they can be replaced by new apprentices. Therefore we urgently need investment in training centres, resources, and trainers to provide apprentices with the

knowledge and practical experience they need.

It also means fostering partnerships between training providers, employers, and government bodies to ensure apprenticeships are aligned with the rapidly evolving needs of the industry; something Skills England has committed to overseeing and we look forward to supporting.

Safety is not an optional add-on—it must be embedded in every stage of training. From understanding the risks of working with electrical systems to safely installing gas and plumbing systems, JTL apprentices are taught to make safety a core part of their skill set and with the latest industry equipment to do so, contributing to their employer and the economy from the outset.

With the UK facing a housing crisis and transitioning to a greener economy, the need for a skilled, safety-conscious workforce has never been more critical. High quality apprenticeships are key to building this workforce.

In the rush to meet homebuilding targets, we cannot afford to cut corners in training the people who will build and service these homes. By investing in apprenticeships that emphasise safety, we can ensure the homes of tomorrow are built to the highest standards, protecting both the people who live in them and those who create them.

Retentions in construction: It’s time for governments to act

In a construction landscape plagued by cash retentions, the survival of small- to mediumsized businesses hangs in the balance. Calum Melville is CEO of Edison Capital explores the longstanding issue of unfair payment practices. Is it time for a legislative overhaul to protect vulnerable ﬁrms and reshape the future of construction in Britain?

Is there a strategy within the construction industry in Britain to drive contractors out of business? Nobody in construction will be surprised to learn that I am talking about cash retentions, the issue which has bedevilled small- to medium-businesses throughout living memory and is still killing them off with depressing regularity. For decades, this practice has burdened small- to medium-sized contractors, who ﬁnd themselves caught in a cycle of delayed payments and ﬁnancial uncertainty.

While larger companies may view retentions as a necessary tool for risk management, many smaller ﬁrms see them as a crippling threat that undermines their viability. We need to be explicit about the shocking behaviour of big companies holding on to money that doesn’t belong to them and the fact that unscrupulous outﬁts are not paying what is owed to their suppliers in the hope that they will go under, and resolve the issue for them.

Unfair behaviour by the big boys remains rife. Only last month, a major Scottish-based contractor was ordered by the High Court to pay a subcontractor £1.1 million when the judge ruled it had mounted a “frivolous defence” and that its arguments were “entirely without merit.”

This is not a new problem. Retentions, which are still the main bugbear, have been a part of the construction industry in the UK for more than 100 years and, in recent times, there has been a growing divide between major companies, which regard them as a useful mechanism, and smaller ﬁrms which almost unanimously see them as a company-destroying blight. A rational analysis of the matter probably lies somewhere in between, but the focus of the construction sector, in which I have become increasingly involved over the past two years, must surely be on whether retentions have a place in a modern industry or whether Government should be legislating against them to foster a more equitable construction sector. First of all, what are retentions? Essentially, they are a percentage of payment held back

We need to be explicit about the shocking behaviour of big companies holding on to money that doesn’t belong to them and the fact that unscrupulous outﬁts are not paying what is owed to their suppliers in the hope that they will go under.

typically by a client or main contractor under a construction contract to act as security, or an assurance that the project works will be completed and that defects which may subsequently develop are remedied.

On the face of it, this seems reasonable, since it would appear to ensure that the contracted works are defect-free and that, in theory, the sub-contractor’s payment is protected until it is released at the end of an agreed period. That is how it would work in an ideal world. But, in the mud and breezeblock world of construction, things can often be seen from a different and signiﬁcantly more jaundiced perspective.

The time between the contract start and the release of the held-back payment can inexplicably lengthen, frequently to the point where the subbie, now fully engaged on other projects, stops trying to collect and writes it down as a loss. It is widely believed in the industry that less responsible contractors have made it a practice to count retentions as part

of their own proﬁt, or as an aid to cashﬂow, and have never had any intention of releasing the sums in question. Or contractors go bust, and the retention monies held go to primary creditors, rather than those to whom it was owed.

Let’s also factor in that, if clients keep 5 per cent of the contract value as job retentions, that could equate to 50 per cent of the proﬁt the contractor expects to make. It could even be 100 per cent. Margins are tight across the board, so it makes it even harder to swallow.

Even when contractors are calculating their returns from a job, they often don’t include existing overheads and, while overlooking this clearly is their fault, it shows they are so desperate to win the work that they are not pricing it properly, and it adds more pressure.

Also, contractors legally need to be on site the whole time, accruing further costs, especially if money is being held back. If they leave, they will be breaching contract and could be in more trouble legally, so they are stuck between a rock and a hard place.

Industry veteran Rudi Klein, former CEO of the SEC Group, said recently that SMEs had lost more than £2.5 billion of retentions, at a conservative estimate, as a result of upstream insolvencies. The Pye Tait Report from seven years ago reckoned that £5 billion was being withheld annually – a ﬁgure that will only have risen in the intervening period.

Just last year, in a less-than-festive Christmas message, Scotland’s Construction Industry Collective Voice said that 73 per cent of survey respondents had experienced severe difﬁculties in securing the release of their retentions.

There have been innumerable Government initiatives over the years, at both Scottish and UK levels, to address the issue – from Build UK’s “roadmap to zero retentions” by 2025, the Get It Right initiative and the 2018 Hackitt Inquiry on building safety – but the practice remains as ﬁrmly entrenched in the construction industry psyche as ever. Last month’s damning Grenfell Inquiry report is long on improving standards – which, it is generally recognised, removing retentions would do – but the best advice would be not to hold your breath on that one.

One potential answer to what is clearly a convoluted and intractable problem might be an adoption of some of the more realistic elements of the Industry Behaviours Charter introduces by Oil and Gas UK’s Efﬁciency Task Force in 2015. As well as a collective commitment to work effectively, efﬁciently and co-operatively, the Charter suggested that differences of view on retained money could focus on the individual part of the contract at issue.

Thus, if the matter in dispute was worth only 5 per cent of the whole contract, then that would mean that 5 per cent wouldn’t be paid rather than holding onto all the monies in the meantime while it was resolved

The GVA of the construction industry in the UK was £108.7 billion, according to number-crunching site Statista, compared to a contribution of £30 billion by the oil and gas sector, which admittedly is winding down.

Action on retentions will eventually have to be at a legislative level. If it can raise standards across the board, create greater transparency and co-operation and avoid the annual cull of small ﬁrms who haven’t been paid for the work they’ve done, then surely it’s worth a try.

Future outlook

The future outlook for cash retention practices in the UK construction industry is increasingly focused on reform and greater transparency. As awareness of the detrimental effects of cash retentions on small- to medium-sized enterprises grows, there is mounting pressure from industry stakeholders, including contractors, advocacy groups, and even some government bodies, to reevaluate and legislate against these practices.

Innovations in technology, such as digital payment platforms, offer potential solutions for improving cash ﬂow management and ensuring timely payments. Additionally, as the construction sector moves toward more collaborative approaches, there is hope that industry standards will evolve to prioritize fairness and accountability.

Ultimately, fostering a culture that values prompt payments could not only bolster

the sustainability of smaller ﬁrms but also enhance the overall health and resilience of the construction industry

Advocacy groups play a pivotal role in supporting contractors and pushing for much-needed legislative changes within the UK construction industry. Organizations such as the Federation of Master Builders (FMB) and the Construction Industry Collective Voice (CICV) have been at the forefront of efforts to raise awareness about the detrimental effects of cash retentions on small- to medium-sized enterprises. These groups actively engage with policymakers, presenting compelling evidence and case studies that highlight the urgent need for reform. Through campaigns, lobbying, and collaborative initiatives, they aim to create a fairer payment culture and protect the interests of vulnerable contractors.

Notably, their advocacy has led to increased discussions in Parliament regarding potential legislation to eliminate or regulate cash retentions, demonstrating the power of collective action in driving positive change within the industry.

Without decisive action, the industry risks losing a vital segment of its workforce, ultimately jeopardizing its own sustainability and growth. Addressing the challenges posed by retentions is not just a matter of fairness; it is essential for fostering a resilient construction sector that can thrive for years to come.

Microwave sensors: The ‘must have’ in your next lighting project

With electricity prices on the rise again, optimising energy efficiency remains a top priority in electrical installations. For lighting, one of the most effective solutions installers can turn to for help is microwave sensors. Chris Anderson, Technical Manager at Ansell Lighting, explains more about this dynamic technology and its installation

Using high-frequency electromagnetic waves to detect movement within a space, microwave sensors provide instant control over lighting use, enhancing energy efficiency and providing precise, responsive illumination.

Ensuring lighting is provided only when an area is occupied, the technology works by adapting to the presence of people and activity within a space, using a principle known as the ‘Doppler Effect’. Here, the microwave sensors continuously emit low-level microwave signals across the area they are installed in. These signals bounce off objects (such as walls) and then return to the sensor which continuously analyses the reflections for any changes in signal pattern caused by movement. When changes are detected, the sensor triggers the lighting system to activate, providing illumination when it is needed.

Hugely versatile, microwave sensors are suitable for use in all types of projects and applications. They are often used in residential settings in spaces such as hallways, garages, and outdoor areas due to the instantaneous on/ off functionality they offer, and in commercial spaces in low-use areas like stairwells, restrooms and storage rooms where lighting is not continuously required.

Ideal for use in upgrade projects, microwave sensors are easily retrofitted as they don’t require extensive rewiring or structural changes. This adaptability makes them a practical solution for improving energy efficiency as you don’t have to overhaul the entire system.

Likewise, in new projects, microwave sensors offer great flexibility and can be seamlessly integrated into custom lighting designs or even smart lighting systems from the outset. For smart buildings, they can work in conjunction with other automated systems, such as HVAC or security systems, to deliver a fully automated and energy-efficient environment. This integration maximises energy savings and ensures that the building’s lighting system operates as efficiently as possible from day one.

For customers, one of the main advantages of using microwave sensors is the impact it can have on energy use. By ensuring lights are only switched on when needed, microwave sensors help in reducing energy consumption, preventing any wastage from lights being left on in unoccupied spaces. This automatic control not only results in lower energy use and therefore lower costs, but contributes to a more sustainable approach, extending the lifespan of bulbs and reducing the carbon footprint of the building concerned. They can also act as a useful security measure, providing light when unauthorised movement is detected helping to deter would-be trespassers.

From a specification point of view, microwave sensors also offer lots of practical benefits. Unlike alternative technology such as passive infrared (PIR), microwave sensors are highly sensitive and as such can detect movement through obstacles such as walls and glass. This

makes them ideal for use in office environments which may have partitioned spaces or retail stores with glass displays. Microwave sensors also have a broad detection range, so they are ideal for use in large spaces such as warehouses, open plan offices, car parks and gardens.

If we consider the installation of the sensors themselves, there are a few conditions to bear in mind when planning their setup. Once such consideration is height and placement. Microwave sensors should be installed at a height where they can effectively cover the desired detection area. Metals, air currents and soundwaves can all cause false triggers so placement near ceiling fans, heating vents, direct sunlight and heavy machinery should be avoided. Microwave sensors should never be installed in metal casings or in close proximity to metal products Many microwave sensors will also have sensitivity settings which must be carefully considered dependent on the environment and application requirements. Higher sensitivity is ideal for larger spaces, while lower sensitivity can be used in smaller or more controlled environments.

As you can see, microwave sensors are a highly effective and versatile option for lighting control in both residential and commercial installations. Their ability to detect movement accurately, even through obstacles, combined with their energysaving benefits, make them a valuable tool in reducing both energy consumption and costs.

Bringing daylight into dark offices

The world’s largest co-working space provider, faces a unique challenge in transforming the historic Battersea Power Station into modern office spaces. With limited natural light in the Grade II listed building, IWG turn to Signify’s NatureConnect lighting system, which simulates daylight to enhance occupant well-being and productivity

When IWG — the world’s largest co-working space company known for Regus and Spaces — acquired space to develop offices at London’s iconic Battersea Power Station, they faced a major obstacle. Battersea Power Station’s iconic structure and heritage, historically supplying a fifth of London’s electricity, meant that the building was not designed for the purpose of today’s development.

One of the limitations of renovating and occupying the Grade II listed building was the lack of windows and natural light. For IWG, and for office spaces in general, one of the key considerations for delivering excellent spaces is the ability to offer comfort and wellbeing to potential occupants. Access to good lighting is crucial in delivering this.

Office workers spend a lot of time indoors, and often in locations without windows or proper access to natural daylight. Studies show that the natural light has a huge impact on productivity and alertness, reduces stress and contributes to better sleep. IWG was looking for a lighting solution that was going to deal with the lack of windows in its workspaces, so approached Signify to understand how they could overcome this challenge and provide a better experience for its customers.

NatureConnect by Signify was suggested as the perfect solution, as it brings the ‘daylight indoors’. So, how does it work?

NatureConnect mimics daylight and replicates the view to the sky using light scenes that boost energy levels and help windowless spaces feel in sync with nature. Different lighting scenes can be selected by occupants, depending on their needs. This includes an extra bright “Energize” scene for an additional energy boost, the “Day Rhythm” scene that automatically adjusts to the correct lighting for the time of day, and a soft, warm “Relax” scene designed to create a calming atmosphere.

NatureConnect has been proven to lead to higher alertness and vitality. The mimicking of natural daylight and the view to the sky enabled via NatureConnect delivers the melanopic boost benefits of bringing the outdoors indoors. A comprehensive study found that employees experience greater alertness under the NatureConnect system, especially those over the age of 41, who benefit significantly from natural light. Additionally, this critical melanopic boost supports a healthy sleep-wake cycle.

From a business perspective it delivers benefits too. NatureConnect leads to higher occupancy rates, which is not just good for the business they work for, but also for the landlord who owns and rents the space. A study conducted with multiple tenants at the Amsterdam Edge

West building in the Netherlands, based on four months measurements and 333 meetings using the Wilcoxon analysis shows:

• Increased occupancy of 48 per cent

• Two hours more occupied per day

• Seven times more full-day bookings

NatureConnect not only delivers the required level of lighting to meet office lighting standards and regulations, but it brings additional benefits for all, too.

With NatureConnect, IWG were able to transform its previously dark, windowless office areas, into productive, inspiring, and relaxing spaces, which not only delighted tenants, but delivered business benefits for IWG too.

Richard Morris, CEO IWG UK commented: “Our locations are more sellable and more attractive if they have a feeling of natural light.”

NatureConnect creates engaging spaces and energises its occupants. It’s not just great for use in offices, it’s also perfect for hospitality and healthcare spaces, where natural light is not always easily accessible.

Circular Lighting Live 2024

The Circular Lighting Live 2024 conference and exhibition, for which Electrical Times was a media partner, was held on 9 October in London. Now in its third year, the conference was packed with new information, initiatives and updates on all issues related to sustainability and lighting. In the morning, the event was split between a lighting manufacturers’ track, and a designers’ track. During the course of the event, it became apparent that there are important changes impacting the industry:

New legislation

Neil McLean of Lutron gave a comprehensive update on the approaches being taken by the EU, and the UK to take 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 plastics

Bart Maeyens, head of 3D Printing at Signify, explained how the company is using additive manufacturing in plastics to provide greater levels of customisation, reduced inventory, greater circularity, and reduced embodied carbon. This was followed by Mark Shortland of Shoplight who discussed the use of bioplastics in luminaire manufacture, and Chris Newman of Albis who highlighted the advances in plastics available for lighting manufacturers.

New environmental metrics

One of the key themes to emerge throughout the day is 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. The service includes an online portal for data entry and a dedicated luminaire tool

LCAs, EPDs, and new plastics: some of the key takeaways from lighting’s go-to sustainability event

that streamlines the process, and minimises the cost, of getting an EPD veriﬁed and published. The work that Glamox have undertaken to decarbonise their operations was described by Birger Holo, the company’s Group Technical Director. He explained that the company had committed to carbons emissions reductions approved by the Science Based Targets Initiative.

New technologies

Bart Maeyens, of Signify explained the range of AI tools the company is now using to enhance manufacturing efﬁciency, to improve scheduling, and to reduce waste. He described how the capacity of AI to review very large quantities of data had enabled the company to ﬁne tune production processes.

New approaches to remanufacture

Simon Fisher of F Mark 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 (pictured above) 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.

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.”

Simon Fisher of F Mark said: “If you are in to lighting, sustainability and the built environment, this is THE event to be going to every year!”

Martin Wherry of Glamox added: “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”

Stewart Langdown of Zencontrol said the event was: “Lighting a truly visual representation of sustainability and how to do it right!”

Caleido Tower scales new heights with ‘gold’ for sustainability

One of the tallest skyscrapers in Spain, which has received more than three million visitors, has been denoted as having excelled in its sustainable design after installing a globally proven KNX building automation system from B.E.G.

Caleido Tower, the seventh tallest building in Spain, has achieved GOLD in the Leadership in Energy and Environmental Design (LEED) certification, which means it ‘serves as exemplary models of sustainability, showcasing the potential for significant environmental impact reduction through thoughtful design and operation.’

The building achieved this by using natural light with the help of an advanced lighting control system by German manufacturer B.E.G. – whose UK HQ is based in Surrey. Caleido Tower also has facial recognition, intelligently controlled lifts and air filtration and ventilation systems are incorporated. B.E.G. predominately used the PICO sensor - one of the smallest KNX detectors in the world. Despite its diameter of only 33 mm, it has a range for motion detection of 10m transversely, 6m frontally and 4m for seated activities, meaning it detects even the smallest movements, such as the operation of a computer mouse.

In addition to a light output (controllable or switchable) and a slave output for extending the detection range, the B.E.G. PICO also has three HVAC outputs with which energy-intensive systems such as air-conditioning units can be controlled. The light output can be used both as an occupancy detector and as a twilight detector (motion-independent control/switching).

The B.E.G. PICO also has functions such as a temperature sensor, presence simulation, corridor function, orientation light function, short presence and self-adjustment of the follow-up time. The short presence, for example, can save additional energy as the follow-up time is reduced to an adjustable percentage if a room is only entered briefly.

Paul Jones, Sales Director of UK & Ireland at B.E.G, said: “Since very large ceiling panels were used, it had to be ensured that the respective panel would not sag over time due to the weight of a detector. Weighing only 14g, the B.E.G. PICO proved ideal and was integrated in all rooms where detectors were planned.

“The building was digitally modelled in advance with BIM - a planning method that is increasingly becoming the standard in the planning of large projects worldwide.

“The combination of bus systems can help to save energy costs. In the Caleido Tower, over 15,000 DALI luminaires were installed in

addition to KNX, while a gateway was used to control these with KNX. This connected the KNX bus with the DALI bus designed for lighting control. Each B.E.G. gateway was able to switch and dim up to 64 ECGs in 16 groups, while scene control of individual ECGs is also possible. In addition to RGB and Tuneable White, the gateway also supported DALI-LINK multi-sensors.

“In the corridors of the tower, the light is controlled by the B.E.G. PICO depending on daylight and presence. If no more movement is detected, the orientation light switches on. The lighting is dimmed down to a value of 10 per cent as soon as the room is no longer occupied.

“With the calendar function, the light is automatically switched off at a preset time in the evenings when there are no more classes and, in addition, no movement is detected in the surrounding areas. This affects the refectory, for example, where the B.E.G. PICO only functions as a twilight detector and only regulates the light to the desired brightness depending on the natural daylight.”

The offices and meeting rooms were also equipped with KNX versions of the B.E.G. PICO with push-button interfaces. The advantage of a push-button interface compared to KNX push-buttons is the ‘free choice of switch programme’. This means that the desired design and an interface with four channels for several rooms can be used.

“The detector can be operated in full automatic or semi-automatic mode,” said Jones. “In the full automatic mode, the light switches on when there is movement, and the brightness falls below the desired value. The user can manually switch the light on or off or dim it by means of a push-button. In semi-automatic mode, the lighting is always switched on via the push-button. Then, as in full automatic mode, the follow-up time is restarted with each movement and the lighting is switched off after the follow-up time has elapsed.

“If the amount of daylight increases, the amount of artificial light decreases accordingly and vice versa. If there is enough daylight, the artificial light is switched off in spite of movement and possibly switched on again later if the level falls below the set value. In addition, the air-conditioning systems are also controlled according to movement in order to additionally save energy.”

In October 2021, the IE Business School was opened in the Caleido Tower in the presence of Felipe VI, King of Spain, and António Guterres, Secretary General of the United Nations.

Mr Guterres said at the time that the IE Tower is ‘a symbol of the importance of education, a place of learning, knowledge generation and answers to the challenges of humanity’ and Mr Jones added “That sums up the Caleido Tower and this project perfectly.”

How construction firms can make sure they’re fire-safety regulated

By Damien McKenna, founder of compliance management software, BORIS Ltd

There are past instances where the construction industry has come under huge scrutiny for the way organisations have failed to comply with fire regulations and were systematically dishonest to customers. Here, Damien McKenna, Founder and Co-owner of BORIS Software Ltd, a compliance and workforce management tool, shares three simple ways that those working in the firestopping sector and other construction settings can ensure they’re fully compliant with the latest regulations.

1. Make fire safety in design and materials a priority

When considering building design and the materials to use, it is paramount to use non-combustible materials. The use of safety approved fire-resistant materials in all areas ranging from cladding, insulation, and internal fittings will minimise the risk of fires starting and spreading. Using an effective digital workforce management platform can ensure accurate stock control and purchase orders features that facilitate ordering and managing the required materials in the correct quantities.

2. Closely follow building regulations

Following building regulations is a basic standard procedure that aligns with the ‘golden

thread’, a concept that ensures contractors have the correct information to understanding the building and steps that follow to ensure the safety of residents and the building itself. In adherence to the golden thread it is also essential for construction firms to be aware of any changes to building regulations which can be achieved by regular audits of projects. Companies that digitise their workforce management are now able to view live digitally marked-up drawings of the site they are working on which show any hazards that need addressing and allow workers to mark it as complete once the job is finished.

3. Strong communication and community engagement

Establishing effective communication methods and swiftly addressing any raised concerns regarding safety will allow residents to feel at ease. The golden thread again proves beneficial in this instance, due to those in charge of the building being obliged to demonstrate that the work completed meets the requirements of building regulations.

Being transparent with the materials used and reiterating any fire safety procedures to be aware of fosters community engagement and protects people’s wellbeing.

It is also important for workers to ensure their own safety is not in jeopardy while working. With BORIS, workers can utilise the bulletin’s function that permits the sending of business wide communications and creates a smooth communication process between members of an organisation. The golden thread requires workers to digitally store vital details of a building before construction has even begun and continues as long as the building exists.

Transitioning to digital workforce management software allows those operating in the construction industry a clearer guide to following safety procedures, ultimately leading to the creation of safer environments.

Grand Design’s Holme House Farm utilises Aico’s HomeLINK Gateway

In the latest series of Grand Designs, Jonny and Cara showcase their journey to build Holme House Farm. With the support of Aico, the couple have created a new accessible home designed to empower Cara, who has faced significant health challenges

When life threw a curveball, Jonny of JS Electrical didn’t just adapt; he dreamt bigger. With a vision to create a home that promised accessibility and independence, Jonny, a seasoned electrician and devoted husband, took the reins of a project that would transform his familiy’s life. From an old stable block to the stunning accessible home featured on Grand Designs, this new home not only safeguards their future but also embodies the spirit of family and resilience.

Before building their new home, Jonny and Cara were living in a townhouse with their son in a nearby village, when in 2019, their lives took an unexpected turn with Cara becoming unwell. After being rushed to hospital, it became clear that she was suffering from an autoimmune disease, causing swelling on the brain and spinal cord which resulted in Cara being paralysed from the waist down. Whilst in the hospital, the couple also found out they were expecting their second child.

This huge life change rendered their current four-story home inaccessible, prompting a move into the bungalow on Cara’s parents’ farmhouse grounds. Although they were now living in a bungalow, it still was not wheelchair friendly. So, in August 2021, Jonny got planning permission to build their new accessible home on the same land. A few weeks later, Cara had the idea to apply for the TV Show, Grand Designs.

With the exciting appearance on Grand Designs looming, the long process of building a home began with the old stable block being demolished in October 2021. This got the site ready for the ground works to take place in February 2022. Giving Cara as much freedom as possible was continuously at the core of the project, with Jonny stating: “If I’m at work, knowing that Cara is much safer on her own is the whole reason we built this house—to give Cara her independence back.”

To keep the project budget low, Jonny completed a large portion of the work himself, such as the fibreglass roofing and electrics. Jonny said: “That’s what everyone thinks, you know, that you become paralysed and get a loan, get a payout for it, and it’s just not the case…for a lot of people, you get paralysed, you lose your job, have to get a new home, and you don’t get any money for it.”

Aico recently re-visited the property during the final stages to catch up with Jonny and walk him through the installation of our Ei1000G Gateway and HomeLINK Environmental Sensors. When choosing the fire alarm system for his home Jonny described it as a “no-brainer”. He installs Aico products professionally and has become very familiar with them. After hearing about the family’s story, Aico generously decided to donate the Multi-Sensor Alarms and Environmental Systems installed in the home. The fire alarm system installed at the property is Grade D1 LD2, with seven Ei3024 MultiSensor Fire Alarms fitted across the hallways,

the kitchen (including the pantry and utility room), and the living room. With sustainability in mind throughout this build, the property is fully electric, which means there was no need to install any carbon monoxide alarms. “In terms of fire safety and coordinating the alarms with the room layout, it ticks all the boxes for peace of mind,” Jonny stated. It was also important to include the Ei450 RadioLINK Alarm Controller which allows Cara to test, locate and silence the alarms at reach.

In addition to installing alarms and points of control, Cara needed to have access to plenty of exits in case of emergencies. This massively impacted the design of the building, including an exit in their bedroom, living room, and kitchen, as well as the front door.

Aico donated three Environmental Sensors, two Ei1020s and one Ei1025, as well as an Ei1000G SmartLINK Gateway. During Daniel’s visit, he assisted Jonny in setting up the system and fitting the sensors. These were strategically placed throughout the kitchen, living room, and bathroom. Jonny went on to discuss the benefits of having the Gateway installed and having alerts sent to the app on his phone. This is beneficial to the family as it comforts them to know Cara is safe, as well as contributing to Cara’s freedom.

This project has been life-changing for the family and Aico is honored to contribute to supporting this transition and making their home safer. Their Grand Designs episode is part 3 of the new series on Channel 4.

We all know someone who is a bit forgetful!

We can all be susceptible to distractions, a knock on the door, a telephone call, a programme on the telly that grabs your attention, taking your mind off the job in hand. If that job is preparing a meal requiring hot oil, the consequences could be catastrophic!

Assisted living accommodation, hostels, holiday cabins, caravans, and the kitchens of people living with dementia, are obvious environments that would benefit from a device that monitor heat levels on a hob and acts if a kitchen is left unattended.

HobSensus is a neat device that combines a heat detecting sensor and a timer. Pressing the red button starts the timer and activates the hob. It is then used in the normal way. If the cooker is left, power will be cut when the timer runs out. However, the clever part is the 64-zone sensor that ‘watches’ the cooking surface, measuring the temperature in each zone. If the heat approaches a dangerous level, an audible warning sounds and the green active lights begin to flash amber.

If no action is taken and the temperature continues to rise, the warning sound becomes more intense and the lights flash red. Then, before flashpoint is reached, the power is cut. Conveniently, this happens before a smoke detector is activated and well in advance of fire alarms sounding. In multi-occupancy dwellings this avoids both evacuation and fire service call outs. In domestic situations, it prevents smoke damage and lingering smells of burning oil as HobSensus acts before a crisis point is met.

HobSensus is easy to install, a competent electrician should take no more than 45 minutes. The Sensor head sits 600mm centrally above the cooking surface. The Power Switching Unit is located between the cooker Isolator switch and the hob. Where possible the two units are connected using low voltage cable, this provides power to the Sensor Head. Where this is not practical, owing to glass splashbacks and the like, 4AA batteries will power the unit for up to two years.

The two units communicate via Bluetooth. When dangerous temperatures are approached, a signal to the Power Switching Unit cuts

power to the hob, rendering the kitchen safe. With a switching capacity of 40 Amps HobSensus will control most electric hobs up to 900mm in width.

With a growing number of avoidable incidents, it’s surprising that timers and sensors that make kitchens safer are not as commonplace as CO2 and smoke detectors.

Electrical Safety First, the campaigning organisation which aims to reduce death and injury caused by electricity is recognised by Government and industry as the leading authority on electrical safety. ESF works with manufacturers, retailers, and consumer safety organisations to improve safety regulations and standards. Perhaps its recognition of kitchen safety issues, by way of last year’s Safety Innovation Award going to HobSensus, will place more emphasis on hob safety.

Such a simple, but effective device, HobSensus is active across numerous student accommodation properties, and since installation not a single hob incident has been reported.

Are care homes safe from fire?

Siemens Building Products and partner Jackson Fire & Security emphasize the importance of competence in fire safety systems for care homes. Effective fire protection must consider the specific needs of elderly occupants, particularly their mobility issues, when selecting appropriate methods to safeguard both residents and the building from fire threats.

The issue of competence was highlighted in a report to CROSS-UK, a confidential system for reporting fire and structural safety concerns. This report, prompted by two incidents shared by the fire and rescue service, suggests a broader competence issue may affect the entire care home sector.

It is vital to have a clear understanding of what is required when it comes to ensuring fire safety in a care home. Fire risk assessments carried out by a competent fire risk assessor should take both the environment and the types of residents and their specific needs into account.

Many care homes operate with older conventional fire alarm systems. The British Standard recommends addressable systems to enable the location of an incident to be identified quickly. Upgrading to an addressable system has cost implications with some systems

requiring not only the replacement of devices but also reconfiguration of the wiring into a loop. Others, such as those from Siemens, do not require such wiring changes (providing the cable is of a good standard), thereby offering considerable savings in installation costs.

The British Standard recommends L1 (maximum life protection automated fire alarm system coverage throughout) in large nursing homes and many specifications for smaller homes will also specify L1 after the appropriate risk assessment. Minimising false alarms is obviously paramount given the inability for occupants to evacuate quickly. Zero false alarms is an even better scenario in an application where an alarm can cause panic, confusion and considerable disruption. Jackson Fire &

Security uses Siemens ASA detectors which include a guarantee of no false alarms, with multi-criteria detection technology which detects a fire incident quickly. Crucial to this is the ASA (Advanced Signal Analysis) which dynamically responds to different fire and deceptive phenomena signals such as toasters or steam. Drift compensation, whereby the detector ensures a constant sensitivity despite any build-up of dust or dirt within the chamber, is another essential feature that ensures consistent performance during a detector’s lifespan.

Training of the personnel responsible for the installation, commissioning and maintenance of a fire alarm system is also fundamental. Steve Jackson is Managing Director of Jackson Fire & Security. He comments: “Whenever we bring a new franchisee on board, we ensure that they receive full training directly from Siemens in the equipment they will be installing. It is important that any care home owner or operator checks the competence of anybody employed to carry out work connected to fire safety. There should be no compromise on competence given that this is a life safety issue. We have wide ranging experience in designing and installing systems for care homes and appreciate the particular challenges they represent.”

SPDs for modern homes

20 years ago, we would have classiﬁed a domestic home as a simple electrical installation. Now, with the massive jump in available technology, does a simple electrical installation even exist anymore? Advances in technology have caused complications in all areas of designing an electrical installation, and the topic of surge protection devices is no different

For a domestic installation the advice has always been quite simple, if it is a normal sized home with one consumer unit, one surge protection device (SPD) will provide you sufﬁcient protection. There has been a bit of confusion around the application of the 10-meter rule, but this is usually for much larger, more complex installations, where external lightning protection systems are installed and requirements of BS EN 62305 must be considered.

In an average sized home, the choice of SPD, again, was quite simple. Most domestic installations would need a type 2 SPD installed in the consumer unit. The only time this would change was in the event that the house was directly fed via an overhead supply, where a type 1,2 & 3 combined SPD should be installed. Installing a combined SPD between the meter and the consumer unit would provide protection in the event of a direct lightning strike to the supply cable feeding the property. In most domestic installation, you would know quite quickly what type of SPD was needed. Once you knew the earthing arrangement, a quick call to your friendly SPD experts and you would have a part number. Easy peasy.

These day we have a few more complications and there are additional questions we need to ask. Does the installation have an EV charger? If so, it is recommended and required by some manufacturers

All of this is easy to navigate with a bit of guidance, but it is deﬁnitely worth thinking about the next time you look at what you think is just a simple job. There are not many of those left!

of chargers to have an SPD installed in order to provide protection to the valuable sensitive electrical equipment. This is even more relevant if the charger being installed has a loss of neutral device. This device is a safety control and it’s there to disconnect the charger in the event of a loss of neutral. However, the sensitive components within this device can be degraded overtime by repetitive switching surges, such as those produced by an inverter – like an EV charger. In this case, it would be recommended to install an SPD local to the car charger. This can be a type 2 SPD and can be installed within the garage unit, supplying the charger. Does the installation have a PV system? If so, it is a requirement in BS7671, that if the installation requires an SPD on the AC side, it is also required on the DC side of a solar PV system. This device is different to the devices you would install on the AC installation and is speciﬁcally designed for the use on the DC

side of the PV system. As it’s very rare to ﬁnd a domestic installation with an external lightning protection system, we can pretty much say for a domestic PV installation, it would be a type 2 SPD. The additional consideration for the selection of a PV SPD is the operating capacity of the inverter. Generally, we would be looking at a 600V/1,000V system, usually a 600V for most domestic installations. So, for our devices, this would be the SPDPV600, and would need to be installed one per string, in parallel with the inverter.

We even have to think about the heating system now. It is no longer down to the heating engineer! The growth in popularity of ground source and air source heat pumps have introduced sensitive control panels. These are extremely expensive to replace and to do so creates downtime of the heating system, which no homeowner will want. If this equipment is installed, it is recommended to look at an SPD local to the control panel or the pump, depending on the installation, to provide suitable overvoltage protection.

We have an ever-expanding technological growth right now in the domestic market. Consumers are concerned with reducing energy usage alongside producing energy, with battery storage and prosumer installations on the rise. There is even see an emerging market for technology that previously we have only seen applied in large industrial settings, such as domestic voltage optimisation, aimed at reducing energy usage.

All of this is easy to navigate with a bit of guidance, but it is deﬁnitely worth thinking about the next time you look at what you think is just a simple job. There are not many of those left!

Mode 4 EV charging: AC side RCD selection

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 publication of ENIEC 61851-1 2017, and the associated changes in section 722 BS7671 2018. 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 BSENIEC61851-23 2014 – the current designated standard for DC charging, quoted in BS7671. 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 manufactures claiming compliance with a designated standard.

Which standard?

The current edition of BS7671 (Oct 24) 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 BS6761 (clause 133.1, 134.1.1 and 531.3.3) to select appropriate RCDs, based on the individual charge point manufacturer’s characteristics and installation recommendations e.g. note minimum RCD characteristic requirements at the quotation stage (Clause 642 (Inspection): Refer to as an aid-memoire during installation planning / equipment veriﬁcation).

Chaz Andrews, Technical Manager at Doepke UK Ltd, discuses the RCD circuit protection associated with Mode 4 charging equipment

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 design and technology employed, equipment containing high power rectiﬁers/ inverters can produce signiﬁcant transients during operation. Check with the equipment manufacturer as 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 function of the individual chargepoint harmonics, produced during various stages of charging and the supply quality (existing harmonic content). The existing standard BSENIEC61851-23 sets minimum protective conductor requirements for Class 1 equipment, where touch currents exceed 3.5mA. Follow the manufacturer’s recommendations if they exceed the requirements of BS7671 543.1 - 543.7.

Unexplained RCD tripping may be the result of insufﬁcient safety margin between the operational leakage current and the RCD sensitivity. Note recommendations in 531.3.2 (ii).

RCD Type

Until recommendations are included in BS7671722, unless otherwise stated by the chargepoint manufacturer, only Type B RCDs (RCCB,RCBO, CBR) should be used upstream of Mode 4 chargepoints - see 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 BS7671 and installation advice provided by the Equipment Manufacturer. Ask before acting and keep in mind the requirements of clause 133.1, 134.1.1 and 531.3.3.

EV charge point operators urged to futureproof installations

With the rapid growth of Electric Vehicle (EV) adoption, operators are urged to futureproof their installations by integrating Autocharge and Plug & Charge technologies. Daniel Forsberg, Marketing Manager EVSE at CTEK, highlights how these advancements will create a seamless and secure charging experience for drivers, paving the way for the future of EV infrastructure

Operators installing or expanding Electric Vehicle (EV) charging are being urged to futureproof their installations by being capable of providing Autocharge for tomorrow’s EV drivers and also being ready for the future innovation of Plug & Charge.

Autocharge and Plug & Charge promise a ‘zero touch’ streamlined charging experience for drivers. They will simply plug into a chargepoint, which will automatically communicate with the vehicle. If a payment method has been previously set up, charging will begin.

One difference is that Autocharge requires the driver to pre-register their vehicle with the charging network’s backend or use an RFID card or authenticate via the app, but only for the ﬁrst charge.

Autocharge is already in some European countries, and although availability in the UK is still limited it is growing. Some charging networks are installing Autocharge-compatible chargepoints and educating consumers on how to register for Autocharge and the advantages they will enjoy.

Autocharge relies on the Open Charge Point Protocol (OCPP), which enables communication between the chargepoint and the backend management systems. Operators, such as car park owners and managers, should be installing chargepoints, such as CTEK’s new CC3, that support the latest OCPP standard, 2.0.1, in order to stay ahead.

Plug & Charge can be seen as the next step beyond Autocharge. For the EV driver, the experience will be even more streamlined. Your vehicle’s identifying data is securely stored within the car itself and recognised by any compatible charging station. You don’t need prior registration with speciﬁc charging

networks. You simply plug in and automatically charge time after time.

For both the operator and whoever is paying for the electricity, Plug & Charge promises enhanced security using encryption, digital signatures and public key infrastructure. This will add additional protection for information about the EV, its owner and their ﬁnancial payment details.

Plug & Charge’s protocols are deﬁned by the ISO 15118 standard. As more EVs are built Plug & Charge-ready, charging operators also need to be specifying chargepoints that are ISO 15118 compatible.

Both Autocharge and Plug & Charge will streamline administration for chargepoint operators (CPOs), reducing overheads. Autocharge is a smaller step for chargepoint operators, easier to implement than full Plug & Charge but, unless a vehicle is pre-registered to the backend, can still require physical

authentication devices for ﬁrst use such as RFID readers.

It makes sense for operators to now be looking to install chargepoints, which enable both Autocharge and Plug & Charge by both supporting OCPP 2.0.1 and meeting ISO 15118.

The ISO 15118-compatible chargepoints, such as CTEK’s CC3, will not only enable Plug & Charge. They will also unlock other innovations governed by the standard. This includes Vehicle-to-Grid (V2G) and Vehicle-toEverything (V2X), paving the way for smarter energy management.”

Autocharge and Plug & Charge are not just for rapid DC charging, they are also ideal for AC charging at destinations where drivers might stop for a while and see charging as an added beneﬁt for their trip, such as shopping centres, leisure venues and hotels – locations where convenience is key.

ELECTRIC vs HYDROGEN

Is a combination of the two the best route to net zero?

At the end of 2023, the House of Commons passed the Zero Emission Vehicle (ZEV) Mandate into law, meaning that by 2030, 80 per cent of new cars and 70 per cent of new vans sold in Great Britain must be zero-emission, with a goal of achieving 100 per cent zero-emission vehicles by 2035. In this article, Simon Farnfield, event director at Advanced Engineering, explains why this requires a dual approach, with electric and hydrogen both serving distinct, yet significant, purposes across a variety of sectors and applications.

EV’s role

Electrification is one of the key strategies for coping with increasing greenhouse gas (GHG) emissions and reducing reliance on fossil fuels.

Electric vehicles (EVs), also known as battery electric vehicles (BEVs), are a viable option because they’re highly energy efficient and reduce local air and noise pollution, as well as GHG emissions.

However, the full environmental benefits of EVs can only be achieved when electricity is generated from emission-free sources, like renewables. Plus, there are limitations in electrification at the time of writing.

The Clean Air Task Force state that class 8 long-haul trucks, which require batteries of about 1-2MWh, can take several hours to charge completely, increasing trip durations by up to 35 per cent. For businesses reliant on transportation efficiency and timely deliveries, longer charging times reduces the overall operational efficiency, requiring additional vehicles to maintain service levels.

EVs are considered better suited for commercial use, due to their versatility and efficiency. They are ideal for short to mediumrange transportation needs, particularly in urban

By Simon Farnfield at Advanced Engineering

settings where distances are relatively short and charging infrastructure is gradually being integrated, with legislation such as the 60 km rule being implemented across Europe.

In addition, when championed against hydrogen, one argument favouring EVs is the question of whether hydrogen is as environmentally friendly as its supporters like to claim. Although hydrogen vehicles emit no emissions during operation, the process of extracting and compressing hydrogen into fuel tanks incurs significant efficiency losses.

Hydrogen for heavy-duty

With that said, there are leading manufacturers, namely Toyota, Honda and Hyundai, who are prioritising fuel cell electric vehicles (FCEVs), which are powered by hydrogen. These manufacturers are expecting that hydrogen will play a prominent role in our energy needs across

future decades. Countering EVs’ argument against hydrogen’s environmental impact, there are greener practices of extraction being developed, such as obtaining hydrogen from biomass. This method involves using organic materials, such as agricultural waste, wood chips or other plant-based matter, to produce hydrogen. What’s more, the Cleantech Group revealed that heavy-duty hydrogen trucks can be refuelled in just 10-15 minutes. FCEVs are, therefore, seen as more suitable for heavy-duty applications like long-haul trucks, buses and industrial machinery, and agricultural combine harvesters. All of these require high energy density and rapid refuelling for demanding operations, where extended range and quick turnaround times are critical.

EVs currently have the upper hand in terms of cost, mainly because of FCEVs not being manufactured at a large scale. Nevertheless, electricity is less expensive than hydrogen on a per-mile basis and EVs are currently more energy efficient and have fewer moving parts, resulting in lower maintenance costs. Despite this, it’s believed that FCEVs will be cheaper to run than BEVs within a decade, as stated in a report from Ballard and Deloitte China.

These insights prove that the debate between BEVs and FCEVs should not be seen as an either-or proposition, but rather as developing green options that will contribute to a sustainable future — just in different ways.

Making the EV dream a reality

By Tom Mennell, Technical Standards Manager, Power Systems UK&I at Schneider Electric talks about increasing the reliability of our infrastructure

Electric Vehicles (EVs) are becoming an increasingly important part of society’s move towards becoming carbon neutral. In fact, the International Energy Agency recently predicted that 17 million electric hybrid vehicles would be sold in 2024. This is up by more than 20 per cent on last year’s numbers and follows new government legislation to drive EV adoption. However, if EV adoption is going to meet the heights that we hope, we need to have the infrastructure in place to support it. Part of this is the need to install large quantities of reliable electric chargers across the UK.

Charging that is both fast and high in power is essential if the general population are to fully get on board with the EV dream. Charging points must also be made available in public spaces – including on-street parking spots and service stations. In these places, to achieve the level of reliability needed, a new approach to energy management will be required; one which prioritises outdoor low-voltage assemblies.

Powering an EV future with low voltage assemblies

In order to power, control and protect the supplies to EV chargers, low-voltage assemblies are essential. Given that most EV charging hubs will be in open spaces, outdoor low-voltage assemblies could offer significant benefits compared to conventional indoor assemblies. Take their size as an example. Outdoor low voltage assemblies require far less space due to the fact that they do not require additional enclosures, housings or location within a building. This often enables the assembly to be located much closer to the chargers. Installation can also be completed much faster because the assembly is delivered as a single unit. This usually also means that both initial and lifetime cost of the product are reduced. Because outdoor assemblies can be located much closer to the point of load, the length and size of cable runs can be substantially reduced. As shorter cable runs result in lower losses, operational costs can also be significantly lowered.

However, when it comes to EVs, the charging application is much more demanding than it usually is for low-voltage assemblies. This can present some unique challenges.

Potential pitfalls and how to avoid

One of the biggest hurdles when it comes to EV charging stations is that traditional electrical systems aren’t designed to handle all circuits operating at full capacity simultaneously. For EV charging stations, this capability is crucial, especially during peak usage on hot summer

days. To address this, it’s necessary to use higherrated components that can manage continuous load and high temperatures, ensuring the system remains reliable and safe even under heavy use.

Earth leakage protection could pose another issue. This is because most EV chargers require a residual current device (RCD) to protect against electric shocks, as mandated by safety standards. However, EV chargers produce small direct currents (DC) that can interfere with standard RCDs. The best solution for this is to use Type B RCDs, which are better at handling these small DC currents, ensuring reliable protection for users.

Protection against electrical faults is also essential, particularly in the event of a fault in the electricity supply, such as a broken open protective neutral (PEN) conductor. Faults like this can pose the risk of electric shock and damage the equipment. To prevent them, electricians should install systems that detect faults and automatically isolate them to prevent accidents. The best tools on the market will cut off the power supply in case of faults and provide comprehensive safety for users.

High temperatures can also impact the performance of EV charging points. To counter the effects of sunlight, assemblies should be tested under simulations to ensure that they can handle the heat. This testing helps in optimising the design and performance of the system to withstand high temperatures and maintain reliability. Enclosures with passive ventilation (IP54 rated) instead of highly sealed ones (IP65 rated) can help to mitigate condensation by allowing natural air flow.

As most assemblies controlling EV supplies are located in areas accessible to the general public. Assemblies used in these applications should

be internal arc fault tested to demonstrate that any arc will be contained within the assembly or directed to a safe area.

Longevity is key when installing these chargers. Therefore, they need to be able to resist corrosion, especially in outdoor harsh environments. A practical solution is to use durable materials like pre-galvanised mild steel with high-quality paint finishes that can last up to 25 years. This approach provides excellent protection and is a cost-effective alternative to stainless steel.

Whilst there are many potential challenges that could impact reliability of EV assemblies, most can be overcome through thoughtful design and advanced technology. And, given that increasing reliability is the key to reducing range anxiety and stress for EV users, it’s well worth the initial investment.

Future proofing

As EV charger technology evolves, the lowvoltage assemblies that form its backbone must also evolve. Whether it’s increases in the number and rating of circuits, a shift from manual to automated operation or further adoption of remote monitoring and control, low-voltage assemblies need to be upgradeable and flexible. As such, they should include adaptable circuit breaker configurations, upgradeable trip units, and provisions for remote monitoring and control. Selecting a product that has been designed with the future in mind is essential in terms of avoiding downtime and reducing costs. Properly designed and verified assemblies are the key to making the EV dream a reality. They do not require additional protective buildings, need less installation space, are quicker to install, are future-proofed, and are more cost-effective.

The need for speed

There needs to be more than conversation around accelerating EV charging infrastructure. Ben Croxford, Delivery Director at Eclipse Power Networks looks at the opportunities that fresh thinking IDNOs are applying to bring EV transition closer

The recent change of government in the UK has spotlighted clean energy and decarbonisation. It has also put the transition to electric vehicles back on track by reinstating the 2030 timeline for phasing out sales of new petrol and diesel vehicles. EVs are a key part of the decarbonisation solution, but they can also be part of the problem. The growth in EV numbers has created a disproportionate demand for power. Driver behaviour has increased the need for rapid (50-149kW) and ultra-rapid (150kW) chargers on public networks, putting more pressure on grid connections. Charge Point Operators (CPOs) and commercial fleet operators want to ensure their applications for power connections from Distribution Network Operators (DNOs) and National Energy System Operator (NESO) are processed quickly to return value in a timely manner.

The demand for electrifying transport in the UK results in a lengthy queue for connections. DNOs and NESO do not prioritize by project, so EV connections are in the same queue as residential, commercial, and renewable generation projects. Connection dates of 10-15 years in the future are common as the queue approaches terawatt levels.

Investment in the UK’s EV charging infrastructure is high. A public EV charging hub offers an attractive revenue opportunity for landowners and retail operators. It’s also necessary for commercial fleets. However, when the timeframe extends due to power access delays, the investment becomes less attractive.

I is for innovation and independent

We need an innovative way to address the connection challenge; one that steps away from traditional DNO methods and works with an Independent Distribution Network Operator (IDNO) for EV connections in new residential and commercial developments, and for fleet and depot charging, LCVs, HGVs, taxis, buses, and emergency vehicles.

Introduced in 2004 to increase competition in electricity distribution, IDNOs, like DNOs, design, own, operate, and maintain electricity networks in the UK. But, their independence differentiates IDNOs from DNOs since they aren’t restricted to a specific geographical area. They can operate nationwide and be more flexible in interpreting standards set by DNOs, which vary regionally. Operating in a competitive market allows IDNOs to adapt to challenges in a way that DNOs aren’t incentivized to. They are more

customer-centric, focusing on broader needs rather than just making a connection. The right IDNO partner works with charging infrastructure developers to reduce risk for investors seeking a three to five-year payback by enabling faster, more cost-effective grid connections.

No one said EV charging infrastructure was simple

Importantly, IDNOs understand the complexity of meeting EV regulations. For any EV charging infrastructure project, there are many moving parts, obstacles, and stakeholders to engage with. Dealing with the DNO for a connection involves liaising with the right person in the right way. It requires understanding the processes and timescales for network reinforcement when needed, while also managing the likelihood of unexpected costs without derailing the project.

Similarly, the IDNO simplifies project delivery, legals, and streetworks by clarifying often unclear process requirements, knowing who to speak to. They make large power connection agreements accessible and handle MPAN data flow issues for the customer. Importantly, they assist with timescales for design reviews and legal completion, addressing legal changes that arise when ‘as-built’ doesn’t match approved designs. This adds value to the project’s build assurance—getting completion certificates for phased projects can be complex.

Land rights are a significant bottleneck. These and planning barriers are being addressed by the new government. Discussions about land rights, ownership, and wayleaves involve multiple parties, and not everyone understands the terminology.

You must cut through a lot of technical jargon when dealing with DNOs, which is why it pays to work with an IDNO who can help translate and simplify the language.

Real-world

experience and engagement

At a recent EV Solution Workshop, Eclipse Power presented its EV energisation customer journey to attendees from across the EV charging ecosystem. The journey focuses on engaging trusted expertise—Eclipse Power has a long track record of successfully designing, owning, operating, and maintaining licensed electricity distribution networks in the UK. We have direct experience in compliance with EV charging regulations and in reducing risk for investors.

The workshop and development of our customer journey were prompted by questions from those facing real-world challenges in connecting EV charging projects, primarily the central question: “How can we improve energisation timescales?” The answer lies in communication and improving processes, while keeping all stakeholders informed with dates and progress at every stage.

Ultimately, accelerating the UK’s EV charging infrastructure requires putting people at the centre of the goal, which should be the focus of sector transformation. More conversation and action are needed to accelerate EV charging infrastructure. With a new government looking to unblock planning restrictions and investment in the green transition, the most transformative time is now.

MFTs: more functions for today’s demands

Multifunction testers (MFTs) will continue to be an essential tool for electrical contractors with expanded test capability, says Steve Dunning, Managing Director at Martindale Electric

Electrical systems are becoming more complex due to renewable technologies and rising electric vehicle usage. Alongside side this, safety standards and testing requirements are also evolving. For electrical contractors and installers, it is more important than ever to have to have a flexible, all-in-one testing device fit for the future. TMultifunction testers ensure compliance with the UK’s 18th Edition Wiring Regulation (BS 7671) and streamline multiple tests. Multifunction installation testers combine several functions into one, making it easier for electricians to carry out multiple tests with a single tool.

The importance of multifunction testers lies in their ability to perform the range of vital tests needed to certify an installation. Basic tests include continuity testing, which checks that electrical circuits are connected correctly and insulation resistance tests to minimize the danger to both users and equipment. Other key functions, such as earth fault loop impedance testing, ensure protective devices like circuit breakers operate correctly in the event of a fault. While residual current device (RCD) testing verifies that RCDs will trip, reducing the risk of electric shock. By offering all these critical tests in one device, MFTs for many years have streamlined the testing process, saving contractors time and increasing overall efficiency. Now when purchasing these tools, users need flexible solutions which can be expanded to cover potential future testing needs.

Choosing the right MFT

Selecting a tester that meets the 18th Edition Wiring Regulations is essential for compliance and safety. Safety is of course critical alongside the dangers of working on electrical installations, contractors often work in environments where transient voltage spikes can occur, selecting an MFT with the correct category rating for the environment is paramount, CAT III 600V / CAT IV 300V rating or above is critical to ensure protection.

The usability of the tester also plays a large role in its effectiveness. A multifunction tester with a user-friendly interface minimises the likelihood of errors during testing. The latest multifunction testers are not limited to simple menus and text results, many can now offer context related help screens and connection

diagrams, making it easier for users to read results quickly and accurately.

A robust, portable tester that can withstand shocks, dust, and moisture is essential for demanding environments. Carry cases allow the tester to remain protected during use and add an extra layer of convenience.

Look for a tester with versatile and expandable testing capabilities. As electrical installations become more advanced, contractors need to ensure their testing equipment is capable of handling emerging technologies. For example, compatibility with EV testing is now essential.

A future-proof tester not only provides more value but also allows electricians to expand their services as the demand for EV charging grows.

One multifunction tester range that has been specifically designed to meet the needs of modern electricians is Martindale Electric’s new ET6000 series. Building on the success of their previous ET4000 range, the ET6000 series takes functionality and ease of use to new heights.

Martindale’s ET6000, ET6300, and ET6500 models offer a variety of features that cater to different user needs, all while complying with the 18th Edition Wiring Regulations.

The ET6000 model is ideal for general installations, is EV-ready and offers enhanced capabilities, including compatibility with the Martindale TL305EV adapter, which enables

dedicated EV charger testing. The flagship ET6500 model, on the other hand, is designed for more advanced applications. It includes onboard memory for storing test results, which is a crucial feature for contractors who need to keep detailed records for compliance and reporting. This model also offers advanced earth testing capabilities, making it perfect for contractors who require a more sophisticated testing solution.

The full-colour TFT display enhances readability, offering help screens and connection diagrams that simplify even the most complex testing processes. This user-friendly interface, combined with the series’ “Test and Go” carry case, ensures that electricians can complete tests quickly and efficiently, without worrying about the durability of their equipment. The case allows the tester to remain protected during use, reducing the need for constant setup and takedown, which can be time-consuming. When selecting an MFT, it is important to consider factors such as compliance with industry standards, safety ratings, ease of use, portability, and future-proofing features. Martindale Electric’s ET6000 series exemplifies these qualities, providing reliable, state-of-theart testing tools that meet today’s needs while preparing them for the future.

Q A

Christelle Barnes, SolarEdge

Can you tell us more about yourself and your role?

I’ve worked in the Solar industry since 2009, after graduating with an Energy Studies degree. I spent a few years working for installation companies in the residential and commercial sectors and then joined SolarEdge in 2016. As Country Manager, I’m responsible for our activities in the UK, deﬁning and executing our strategy and supporting our local sales, marketing and service teams. I’m also Vice Chair at Solar Energy UK, a trade association representing over 400 businesses in the UK solar industry.

What ﬁrst interested you in being part of the industry and how did you join?

: A:

I initially went to University in 2006 to do a chemistry degree, the ﬁrst year was pre-med which I didn’t enjoy. I changed physics, but struggled to see what a career in physics could look like. At the end of my ﬁrst year, I stumbled across an Energy Studies degree run by the Physics department. At the time the recession was beginning, and there was more discussion about climate change in the media, so it felt like a good move.

How has the industry changed since you started?

In 2009, solar made up only 0.5 per cent of the worlds electricity generation and there were only a handful of countries actively deploying solar, and in almost all cases required subsidies. The main projects I worked on were off-grid or for very wealthy clients who wanted to be one step ahead. Solar arrays tended to utilise traditional technology and were limited in use case. Fast forward to 2024 and solar is the fastest growing renewable technology, contributing around 5 per cent of the world’s electricity generation. Systems are smarter, incorporating module level power electronics, battery storage, energy management, and energy optimisation software to maximise the value for the system owner. The increased deployment and technology improvements have made solar more cost effective and is

now subsidy free. The systems we install today are aesthetically more pleasing too which contributes to a wider adoption of solar.

What’s the biggest challenge facing the industry?

The two themes which come up regularly in conversation with our customers and partners are skills shortages and grid connection issues. We have a strong and consistent focus on training, helping our installers to upskill, no matter what their role in the industry.

Technology advancements are helping to address grid connection issues, for example, our SolarEdge Home solution utilises DC coupled batteries, and up to 200 per cent oversizing to support larger systems with battery storage, so we are doing what we can to help navigate these challenges.

Thoughts on the future of the industry?

The government and industry have an ambition of 70GW of solar in the UK by 2035, a signiﬁcant increase from the 17GW solar capacity as of July 2024. This goal is especially remarkable when you compare it to the less than 1GW of installed

capacity in 2010, so hopefully the future looks to be ﬁlled with solar!

: A:

What’s new for SolarEdge?

We’ve recently launched our ﬁrst dedicated solution for medium to large scale utility-scale solar, TerraMax, and CSS-OD, which is our commercial battery system, providing an intelligent storage solution for Commercial PV Installations utilising SolarEdge inverters. The CSS will be managed by our new energy optimization platform, SolarEdge ONE for C&I, which is designed to monitor and manage the battery’s performance, and consistently analyse real-time data and user preference. This will allow it to control the battery’s functionality and support various use-cases for maximum savings.

What’s next for

SolarEdge

UK?

We’ll continue, as we have done since 2010, to support our local installers, and to bring solutions that meet the needs of them and their customers. More broadly, as the demand for clean energy solutions continues to rise, especially in light of the UK’s ambitious carbon-neutral goals by 2050, we are focusing our efforts on expanding our smart energy solutions, in particular in residential, commercial-scale and EV charging solutions.

The green energy transition must be done in a way that promotes sustainable growth, those who’ve been in the solar industry as long as I have will be in agreement! In line with this, the UK has increasing focus on safety. This focus goes beyond physical safety, with cybersecurity creeping into more speciﬁcations and decision making processes. This year, the government published a full draft of the PSTI security requirements for connected products, which offered a good starting point, but we would not be surprised to see further developments in regulation over the coming year. SolarEdge have always prioritised safety, both physical and digital, and will continue to ensure our products continue to not only meet, but exceed any regulatory requirements.

From the publishers of Codebreakers

The NAPIT Technical Team and other key stakeholders in the renewable energy industry have developed a NEW Solar PV practical guide. It’s designed to help electricians and renewable energy installers gain a better understanding of, and improve their ability to design, install and commission, solar photovoltaic (PV) systems.

Hitting all the right notes in life and ﬁtness

Dama Lamont, project design engineer at UK Power Networks, talks to Lisa Peake about pursuing passions that create a fulﬁlling life ﬁlled with purpose and connection

Ibegan my journey with UK Power Networks in 2000, starting in the call centre. Since then, I’ve taken on various roles, including Call Centre Agent, Desktop Quoter, Project Manager, and now, Project Designer.

Coming from the NHS, I had no previous electrical experience, but over the years I have acquired a wealth of electrical knowledge. I enjoy being able to share this with customers, assisting them with their requests for works and helping them to understand the process, which sometimes can be complex.

Finding ﬁtness in uncertain times

I started my fitness journey in 2020 (yes, during the lockdown) when I joined Wolf Approach Fitness. When I first joined, we were allowed to meet up in small socially distanced groups, but it was then taken online when we went into complete lockdown. Nowadays, we meet in their gym during the week, and at a local park at the weekends. There is also a running club and fitness retreats. The most recent one I attended was earlier this year in St. Davids, Wales.

It’s a fun and friendly group for ﬁtness at all levels, and the times of classes are varied so you can always ﬁt one or two in around your weekly schedule.

Conquering mud, rain, and personal limits

The Very Muddy Race For Life is an annual event organised by Cancer Research UK. Competitors sign up and seek sponsorship to complete races of various levels and distances. All the money raised goes to Cancer Research UK to help with their work and ultimately finding a cure.

I have done it twice. The first time, our trainer at Wolf Approach decided to get a group together to take part in the Pretty Muddy 5k challenge. We started a running club around eight weeks prior to the event where we built up our fitness levels to enable

us to run the distance. I was drawn to the idea because I have close family members and friends who have been diagnosed with cancer.

At the most recent event, as soon as we parked, the heavens opened, leaving us all stuck in our cars. Fortunately, it let up for a while, and at about one kilometer into the race, the sun broke through. The rain did return, but our friends and family who had come along for support were there to cheer us on through the downpour.

The team supported each other well during the race, slowing down and waiting for each other. It wasn’t a case of who could finish first, it was more about reaching the finish line together. When we got there, we ran across it holding hands. It was superb!

Voices of faith

As a child, I always attended church with my family and I sang in the Sunday school choir and youth choir. I now sing in church on Sundays as part of a band.

We have various musicians and singers, and we have a rota where you sing on average once or twice a month, excluding seasonal events. I have been attending my church for 12 years and pretty much starting singing gospel with them straight away.

I am also in a choir at work called Electric Harmony. We sing a variety of different genres and styles, mainly once a year for our annual Living Our Values award ceremony. We have also done a Christmas event for one of the directorates within the company. Electric Harmony was formed eight years ago by the Engagement team. We are a group of employees from across the business that enjoy singing and love music.

Every moment that I am singing is a ‘best’ moment. I am drawn to a song, tune, melody or harmony that sounds good to the ear rather than any one genre or artist. I enjoy listering to playlists of different genres, with the majority being gospel.

Quality skills for large scale retroﬁt key to net zero success

An industry expert is urging the new government to ensure it includes the development and prioritisation of retroﬁt training and knowledge as part of its focus on skills

An industry expert is urging the new government to ensure it includes the development and prioritisation of retroﬁt training and knowledge as part of its focus on skills.

The call followed the King’s announcement earlier this year of the Skills Bill, outlining the new government’s legislative agenda for the year and designs to remove barriers to learning and bring together local and national government, business, skills providers, and unions to develop a highly trained workforce.

As the government has also announced plans to build 1.5 million new homes in the next ﬁve years and reinstate housebuilding targets for local councils, concern is also being raised around ensuring the decarbonisation of existing housing stock remains a priority.

With around 27 million homes contributing approximately 20 per cent of the UK’s carbon emissions, the government is committed to achieving a 100 per cent reduction in net emissions by 2050. As such, David Pierpoint, CEO of The Retrofit Academy, is urging the government to ensure there is a strong focus on developing the skills needed for the high-quality retrofitting of our existing homes to make them healthier, warmer, and more sustainable. Without this focus, the organisation is concerned that efforts to improve homes across the UK will lose momentum and that the risk of poor-quality retrofit work will increase, with potentially adverse effects on both occupants and the environment.

David believes that investing in retrofit skills is critical not only for environmental goals but also for economic growth and job creation. By equipping workers with the knowledge to carry out effective retrofit projects, the UK can pave the way for a new wave of green jobs that contribute to both local economies and national targets. “The importance of a well-trained retrofit workforce cannot be overstated,” David says. “We are facing a climate crisis, and with buildings as a significant contributor to carbon emissions, we need skilled professionals who can deliver effective and sustainable retrofit solutions. Investing in retrofit training is an investment in our future—environmentally, socially, and economically.”

Speaking on this challenge, David said: “It is fantastic to see the government prioritising the development of a highly skilled workforce in the

UK by bringing together businesses, providers, unions, Mayoral Combined Authorities, and the national government. For many years we have been working closely with such organisations to make this a reality for retroﬁt skills, and we have been making great strides in doing so, but there remains a signiﬁcant challenge ahead.

“It is vital that the incoming government continues to fund quality retroﬁt at scale, including the training required to create the retroﬁt workforce this requires. We understand the importance of building new homes in providing more people in the UK with a warm and comfortable place to live. However, there are millions of homes that are already available that need upgrading to provide the same, and to help us progress to net zero. As the government has said, collaboration is key to developing the skills to make this a success, and we urge them to continue to drive the policy and funding that will make this possible.”

In order to ensure that quality is built into retrofit from the outset, The Retrofit Academy has been developing and delivering leading accredited courses to equip people with the tools that they need to take on roles laid out in the PAS 2035 Standard – the official framework for whole-house retrofit in the UK. By collaborating with industry experts and leading practitioners, and through continuous

development in alignment with retrofit standards, The Retrofit Academy embeds quality into the training process and resources, instilling the responsibility of getting retrofit carried out to the correct high standard first time and at scale.

David said: “Quality is everything when it comes to retrofit. It has to be carried out to the highest standard the first time, with no exceptions or excuses. This means quality should be built in at every level, from the training courses to the continuous development, accreditation processes, and work afterward. This also means that policy and funding should actively promote the best quality retrofit, which is why we are urging the government to make this a priority within its Skills Bill and wider housing policy.”

As demand for green skills continues to grow, the training programs provided by The Retrofit Academy are increasingly essential. They empower individuals to step into rewarding careers that make a real difference in communities across the UK. A well-trained workforce will not only drive improvements in energy efficiency but also improve living conditions for millions by tackling issues like inadequate insulation and outdated heating systems.

Revolutionary technology enhances rail infrastructure safety and efficiency

Penta UKI, a leader in advanced electrical safety solutions, proudly announces the launch of the CTS Tension Meter, a groundbreaking tool designed specifically to enhance safety and operational efficiency within the rail network. The CTS (Cable Tension System) is a state-of-the-art device that provides precise, real-time measurements of tension in overhead catenary systems, ensuring that rail infrastructure meets the highest standards of safety and reliability.

As rail networks continue to expand, so does the demand for dependable, advanced monitoring tools that guarantee the smooth operation of trains and ensure public safety. The CTS Tension Meter is engineered to meet these requirements, offering unmatched precision and ease of use for rail engineers and technicians.

Once fitted to the cable, measurements are delivered via Bluetooth to a mobile phone via the app. With an intuitive digital display and easy-to-use controls, the CTS simplifies the process of monitoring cable tension, reducing time spent on inspections and improving overall efficiency.

Kevin Rushton, Managing DIrector at PENTA UKI, commented on the release: "The CTS Tension Meter is a game-changer for the rail industry. With this device, we are helping rail operators maintain the integrity of their overhead line systems while improving efficiency and safety. Our mission is to support the ongoing development of rail infrastructure, ensuring that rail networks can meet the demands of the future."

The CTS Tension Meter has already garnered interest from key players in the rail industry, with several major rail networks adopting the technology to enhance their inspection and maintenance routines. By providing real-time, accurate data, the CTS allows operators to make informed decisions, reducing the risk of costly disruptions and accidents caused by incorrect tension on the contact wire. www.pbwel.com

Standing the test of time

Sangamo has been manufacturing its Round Pattern Time Switches for over 65 years, and in that time has sold more than 11 million units.

The Round Pattern Time Switch is trusted by installers for a wide variety of applications, not just because of its reliability but its ease of use. The simple dial and levers make setting the switch up for daily fixed timings a breeze with no complicated menu options to navigate through. All Round Pattern Time Switches are also 20 Amp rated, providing a more robust switch than most other products on the market.

The switches are split into four categories:

a) Basic ‘black dial’ 24-hour time clock for simple on and off switching of up to 20A

b) Standard 24-hour ‘red dial’ switch with added 100 hour battery reserve

c) Solar Range - specially designed for lighting applications

d) Digital Range - the newest addition combines the high capacity and reliability of the electro-mechanical models but provides full seven-day programming.

Sangamo regularly hears from people with Round Pattern Time Switches still going strong after 40 and 50 years. When they eventually need a new switch, they reasonably assume, because of its age, that it might not be possible to get a direct like for like replacement. However, because the original design has never needed to be updated, an RPTS you buy today is completely interchangeable with one bought decades ago.

The Sangamo range of specialist time switches and heating controls is distributed through Scolmore Group company, ESP. www.espuk.com
