Warwickshire contractor grows team after energy support boost

A Warwickshire electrical contractor has recruited extra staff and transformed its premises after receiving financial support from an energy efficiency programme. Hertz Electrical was started in 2018 by Andy Wood in Somers Road, Rugby, with four employees to provide electrical installation and maintenance for domestic and commercial customers throughout Coventry and Warwickshire. The 130m2 premises were in need of a complete overhaul to take the business to the next level so Andy got in touch with Coventry and Warwickshire Growth Hub to see if there was any support available. Adam Plumb, who covers Rugby for the Growth Hub, put Andy in touch with the Warwickshire Business Energy Advice Service (WBEAS). The pilot BEAS programme is being run in the West Midlands through the West Midlands Combined Authority with Warwickshire County Council being allocated £1.25 million, with further funding from the UK Shared Prosperity Fund, via Warwickshire’s five District and Borough Councils. Warwickshire County Council has appointed Coventry City Council to carry out the energy audits and this was completed by Business Energy Adviser Denise Osborne. That led to Hertz Electrical successfully applying to Warwickshire County Council for a WBEAS grant of £37,561 for a roller shutter door, double glazing, wall insulation, roof insulation, a water heater and voltage optimiser. Andy said a total of £150,000 had been invested to totally upgrade the site which has also led to three new recruits this year – a solar apprentice and two fully-qualified electricians – to take the number of employees to 16. He says, “Previously, the insulation was non-existent, which meant it was always cold even when the heating was on, there was limited desk space and storage space was a struggle. “Now, the walls are fully insulated, which has made it much warmer. We fitted solar panels ourselves, the water heater has been upgraded, and we now have enough room to store solar panels. “We have new furniture, carpets and LED lighting and the whole place has been painted, so we are feeling more confident about the future. “We’re in a growing business sector because of the push towards renewables and the changes in technology. Over the last five years there has been so many changes in the industry. “We really appreciate having the grant because without it we wouldn’t have been able to make these changes for another two years. We needed better premises to support our growth and now we have that.” WBEAS was launched as part of the £4.6 million Business Growth Warwickshire Programme developed and commissioned jointly by Warwickshire County Council and the five district and borough councils in the county, with funding from the UK Shared Prosperity Fund and the County Council. The Department for Energy Security and Net Zero is funding an expansion to the service as part of the West Midlands Combined Authority-led pilot.

Carhartt launches Tencel Fibre Series for women

Carhartt has unveiled its Tencel Fibre Series for women, a collection of lightweight, breathable and durable workwear. Developed using Tencel Lyocell fibres, the range brings together comfort, performance and sustainability. Carhartt’s Tencel Fibre Series was created in direct response to feedback from tradeswomen who wanted lighter workwear that could handle tough conditions without feeling heavy or restrictive. The result is a collection that’s lighter, softer and more versatile, with every piece built to deliver long-lasting performance. Each piece in Carhartt’s new range is designed to move easily between work and downtime. T-shirts in the collection have a relaxed fit, lightweight feel and practical details like rib knit collars and chest pockets. The short sleeve Crewneck T-Shirt comes in a range of colours including soft rose, barnwood, oat milk heather and wisteria, offering a fresh take on traditional workwear tones. A long-sleeve option is also available, cut with extra room to move and built with the same lightweight Tencel fibres to ensure breathability and comfort in warmer weather. The range also includes a midweight French Terry Crewneck Sweatshirt that balances softness with strength, making it a reliable go-to for both job sites and off-duty wear. A midweight Half-Zip Sweatshirt is available in black or oat milk, in a relaxed fit for easy layering. Powered by Tencel fibres, both sweatshirts offer an extra-soft feel with the resilience to stand up to repeated use and washing. Tencel Lyocell fibres are made from sustainably sourced wood pulp and are both biodegradable and environmentally responsible. Despite their softness, these fibres offer exceptional strength, making them ideal for durable workwear. The fabric’s breathability plays a key role in keeping wearers comfortable in warm or physically demanding environments. By allowing good airflow and wicking moisture away from the skin, it helps prevent overheating and keeps the wearer dry throughout the day. For more from Cahartt click here. 

Almost half of Brits aren’t aware of RCDs

A survey commissioned by NICEIC says that 46% of Brits don’t know what Residual Current Devices (RCDs) are and only 16% know if their home has one. As summer approaches, the nation’s use of electrical outdoor appliances and gadgets will increase. Recent research has found 96% of garden electrical products fail safety tests due to substandard plugs, counterfeit fuses and water ingress, meaning that RCDs could be lifesaving.  RCDs are designed to automatically cut off power if an earth fault is detected in indoor and outdoor electrical circuits, helping to prevent electric shocks, fires and potentially expensive damage. It is recommended that they are tested regularly by pressing the test button on the RCD every six months. The data also reveals that young people (aged 25-34) are the most likely to say they know what an RCD is, with just 32% being unfamiliar with the device. 29% know their home has at least one RCD. By comparison, 52% of respondents aged 55 and over are unfamiliar and only 17% know if their home has RCDs installed. Regionally, awareness is lowest in Northern Ireland and Wales, with half of respondents saying they don't know what an RCD is. The Northwest follows closely behind at just over 49%, with the East of England at 48%. At the other end of the scale, the Northeast has the highest awareness level, with only 35% unaware of the device, followed by Greater London (40%) and the East Midlands (41%). There are also marked differences between homeowners and those privately renting. 49% of respondents living in private rental accommodation don’t know what an RCD is, compared to 44% of homeowners with a mortgage and 43% of homeowners without a mortgage. Paul Collins, Technical Director of the NICEIC, says,"Whilst there are some regional differences when it comes to awareness of RCDs, the research does show that there is a lack of knowledge across the board.” “Because RCDs ensure that certain electrical faults are detected and power is quickly shut off, they play a crucial role in preventing electric shocks, fires, and other potentially life-threatening accidents.” “If you notice your RCD tripping repeatedly, it’s a clear sign that something is wrong and your RCD has done its job - this should not be ignored. It indicates a fault that will require attention. Don’t take the risk of leaving it unchecked.” “RCDs are easy to test. Simply press the test button on your RCD every 6 months - this is a quick and simple way to make sure your RCD is working correctly.” “When you press the test button the RCD trips and the power is switched off. However, if the RCD doesn't trip, it may indicate a problem and you should contact a NICEIC-registered electrician to have it checked.” “It's crucial that homeowners understand the importance of having a fully functioning RCD in place and that any electrical work, including the installation or replacement of an RCD, should always be carried out by a NICEIC-registered electrician.” “If you’re unsure or uncomfortable testing your RCD yourself, a registered electrician can carry out a full safety check to ensure everything is functioning properly, giving you peace of mind.” For more from NICEIC click here. 

NAPIT offers advice as part of Mental Health Awareness Week

Mental Health Awareness Week and Learning at Work Week 2025 (LAW Week) are both taking place from 12-18 May, with the theme of ‘community’ for Mental Health Awareness week, and ‘get connected’ for LAW Week. By combining these themes, NAPIT aims to connect through learning experiences that support mental wellbeing. This week, NAPIT is exploring how building community and connecting in the workplace have positive effects on our mental wellbeing. Being part of a positive community helps us to feel supported and gives a sense of belonging. In hard times, having a community and connecting with people provides support, safety and helps us remember we are not alone. To celebrate the power of community in support of mental health and wellbeing, throughout the week, NAPIT staff are encouraged to take part in an afternoon walk led by different staff members each day. This allows staff to have the opportunity to spend time outdoors and connect with others. Nature plays a huge role in our wellbeing, and research shows that people who are more connected with nature are usually happier in life and more likely to report feeling their lives are worthwhile. In a report from the Mental Health Foundation, it states that nature can generate many positive emotions, such as calmness, joy, and creativity and can facilitate concentration. With this in mind, NAPIT staff are encouraged to go outside into the scenic nature surrounding our NAPIT HQ at the Pleasley Vale Mills in Derbyshire. This will help staff strengthen their connections, encourage positive discussions and get closer to nature. NAPIT's staff will also be able to take part in chat sessions with coffee, tea and cake to encourage more discussions and continue the opportunity to connect. Commercial and Compliance Director, Stephen Melton, says, “We want to emphasise the importance of being part of a community and having a network of supportive people. Building connections can make such a difference in your mental wellbeing. “At NAPIT, we are proud to be able to support our staff. I hope that we can encourage NAPIT members and all tradespeople to check in with each other and seek support if needed. We must learn and share how we can recognise mental health struggles and what support is available. “Each year, NAPIT raises money for a chosen charity through different fundraising events. This year, our chosen charity is The Samaritans, a suicide prevention charity that has a 24/7 helpline for people thinking about suicide. “We are proud to support The Samaritans and hope to continue to encourage more conversations and connections to improve mental health.” NAPIT has put together the following resources and contacts that offer assistance: Contacts The Samaritans offers emotional support 24 hours a day – in full confidence.

Share your own experiences – being open about tough days helps normalise conversations about mental health. Know where to find help – whether it’s a friend, a helpline or a charity, having somewhere to turn matters.

BS7671 Amendment 2 - heat pump installations – Type B RCDs

By Chaz Andrews, Technical Manager, Doepke UK Ltd Heat pumps (HP) producing leakage currents above 1kHz, will not be compatible with Type B RCDs that are only manufactured to meet the lowest requirement of BSEN62423, i.e. operation up to 1kHz. Type B RCDs rated for use up to 1kHz may trip unexpectedly when subjected to leakage currents above 1kHz, or worse, the detection circuit may be saturated (blinded). This will result in the device not detecting residual currents under fault conditions. BS7671 offers essential guidance for the installation design for those who have the experience to ask the right questions. If unsure, the 'skilled person' will seek the advice of the HP and RCD manufacturers to verify that the characteristics of the equipment they intend to use are compatible. Compatibility of characteristics – ref BS 7671 134.1.1 “The installation of electrical equipment shall take account of manufacturers’ instructions. The Domestic Heat Pump Safety Standard BSEN 60335-2-40: 2024+A112024 advises that manufacturers state in their instructions the use of 30mA RCD protection for equipment that is permanently connected to fixed wiring. Check the manufacturers’ instructions relating to specification requirements for RCD protection. Modern HPs contain larger inverters, the characteristics of which must be considered when designing the installation. Installers who have not been involved in commercial or industrial applications may not have had experience with this type of equipment or the application of Type B RCDs. Type B for use with HPs – understanding the standards Leakage current in AC circuits is an inherent function of circuit capacitance and increases as a function of frequency. Modern HPs, to improve efficiency, apply inverter technology with switching frequencies in the kHz range. HP leakage current and the associated harmonic currents must not have a detrimental effect on the protection offered by the RCD, and the RCD should not trip due to normal circuit leakage current. At the time of writing, BS7671 Appendix 1 refers to BSEN62423 2012 for Type B: To claim compliance, RCDs do not have to work above 1kHz. The VDE standard 0664-400 (B+) sets an upper limit of 20 kHz.* This is a recognised issue for larger inverter applications, usually associated with non-domestic installations. Doepke and several European manufacturers’ Type B RCDs exceed the requirements of the existing BSEN standard and the VDE standard. Consequently, for applications exceeding the 1kHz value (see clause 133.1.1), reference must be made to the individual manufacturer’s Type B RCD characteristics and the HP manufacturer’s instructions, relating to the compatibility of upstream protection devices. The diagram below gives an example of two 30mA Doepke Type B characteristics for use with Heat Pumps. Red dashed line shows the existing 1kHz requirement for BSEN 624232). Doepke Type B RCCBs will operate <150kHz, the graph is truncated at 100kHz to increase the horizontal axis (readability).   Grey shaded area: Tripping characteristic for DFS. HP and DFS. BSK* Blue line: 20kHz limit of operation for VDE 0664-400 B+ Green line: DFS HP operating limit 150kHz HP leakage currents >20kHz result from incorrect EMC protection or high supply harmonics Example: If 150mA leakage current at say 4kHz flows in the circuit, it should not trip the RCD  *The performance limit for an RCD with regard to frequency, is a function of the quality and properties of the magnetic materials and the design of detection circuits used in the product: Characteristics above 1kHz are based on extrapolation of the tripping requirements in 62423 and the advice /limits given in IEC60479-2 thresholds <150kHz. The Doepke 30mA HP and BSK characteristics are within the threshold limits for ventricular fibrillation <150kHz / IEC609479-2. Conclusion Greener homes require more innovative solutions (equipment) than those traditionally associated with domestic installations. This involves consideration of the characteristics of the equipment we intend to supply with electricity. Manufacturers such as Doepke publish characteristics for their Type B RCCBs; these can be used to verify that they are compatible with the HP model. HP manufacturers who do not clearly state RCD compatibility requirements risk costly rework when things go wrong. In addition to safety, using inappropriate products in the HP installation will result in system availability problems for the final customer. This, in turn, affects the reputation of the HP brand and the companies involved in the installation. As with any complex equipment, HP characteristics vary from one manufacturer to another. Consequently, the design of the electrical supply requirements and associated protection devices may differ. This must be considered with the individual site design requirements based on BS7671 and HP manufacturer’s recommendations.

Luceco provides lighting upgrades at Akzo Nobel

Luceco has helped Akzo Nobel, a Dutch chemical company, to upgrade the lighting system in the Polymer Plant Controls Room at its facilities in Gateshead. Working with electrical contractors, NEP Services, Luceco replaced the former wired wall switch and handheld remote-controlled lighting to a widely accessible digital dimming solution that works with the lighting specialists’ flagship LuxPanel Backlit LED panels. The room was first modelled using lighting design software, Relux, to confirm illuminance levels. Based on this, Luceco then recommended its flexible Platform technology for ease of use and speed of installation. The LuxPanel Extra features backlit LED panels with modules mounted to the rear of the panel body, enabling direct downward light distribution. This eliminates the need for a Light Guide Plate (LGP), resulting in enhanced performance and balanced illumination. Lighting in the LuxPanel range is compatible with Luceco’s Platform wireless lighting controls, and the Platform technology transforms existing lighting installations into an intelligent, wireless communications system. It’s designed as a scalable retrofit solution that enables full lighting control including dimming, presence detection, daylight control and emergency lighting testing. Reducing energy consumption and lowering operating costs, these features future-proof lighting systems with a cost-effective and non-disruptive installation. To ensure compliance with safety standards, Luceco also recommended upgrading emergency lighting in the space using its Tempus Exit Boxes and Bulkheads. Leman Harris, Luceco Project Manager, comments, “The client asked us to upgrade the old remote-controlled lighting system to something that could be easily controlled by multiple members of staff at once. Luceco’s Platform technology, paired with the LuxPanels, means the staff can now dim the lighting in the room at a touch of the button on their individual phones, rather than sharing one remote control or a hard wired switch on the wall. We are grateful to NEP services for choosing us to work on this excellent project at Akzo Nobel.” Adam Little, Electrical Supervisor at NEP Services, adds, “Luceco have worked with us on projects before, and when we are asked to install a more flexible, up to date lighting system, we knew that their products would work well for the job. The installation was quick and easy and the client is very happy with the results.” For more from Luceco, click here.
