It might seem like all we’ve talked about lately is sustainability, smarter homes, and energy efficiency — and for good reason. These aren't just buzzwords anymore, they're shaping how homes are built, retrofitted and maintained across the UK. As electricians and contractors, you're at a forefront of this change, helping customers make choices that improve not only comfort, but also cut energy bills, and support a greener, more efficient future. While price, ease of installation, and customer preference are still important, sustainability and energy performance are now key to every install. This month, we’ve partnered with Ecostrad to explore the upcoming energy-efficiency regulations for rental properties and what these mean for landlords, and importantly, the opportunities these create for you. We’ll also highlight Ecostrad’s new Magma HHR storage heater, a future-ready, compliant solution for landlords upgrading their properties to meet the new standards. What’s Changing with Rental Energy-Efficiency Rules   The UK government plans to raise the minimum Energy Performance Certificate (EPC) rating for all rented homes to rating C by 2030. According to the government, currently less than 48%  of private rented homes in England have an EPC rating of C and above. Currently, the minimum EPC rating for private rental properties is E, meaning millions of properties will require energy-efficiency upgrades over the next few years. The move aims to help to: Reduce fuel poverty and heating costs for renters Improve overall housing quality and comfort Supports the UK’s commitment to achieving net zero carbon emissions by 2050.   What is an EPC Rating and What's Changing? An EPC measures a property’s overall energy efficiency, breaking down different aspects such as insulation, heating, windows and lighting. It rates the property from A-G, with A being the most energy-efficient.   The government is also developing a new assessment model, the Home Energy Model (HEM),  which will replace the current Standard Assessment Procedure (SAP) .  One flaw with the current SAP is how electric heating is rated in terms of energy efficiency. SAP is more about the base unit cost of energy and gas heating often ranks higher than modern electric radiators and heat pumps, even when they’re more sustainable and controllable.  The new proposed HEM approach introduces multiple metrics to better reflect real-world performance:   Energy cost  – how efficiency affects bills  Carbon  – estimated emissions from energy use  Energy use  – total consumption and potential for improvement  Fabric performance  – how well a building retains heat  Heating system  – efficiency and environmental impact of heating sources  Smart readiness  – ability to adopt smart tech for optimisation and tariff savings  Why this Matters to Electricians and Contractors:   As these regulations move closer, landlords across the UK will start upgrading outdated heating systems, creating a major opportunity for electricians and contractors.  By staying informed and confident about energy-efficient solutions, you can position yourself as not just an installer, but as a trusted energy-efficiency advisor. Landlords will be looking to you for: Guidance on compliant, cost-effective upgrades  Advice on smart, efficient systems that improve EPC ratings Reliable installation and maintenance support    The trade is shifting fast. Electricians who understand the new energy landscape will not only help customers stay compliant but also win more work, build stronger client relationships, and future-proof their business. Future-Ready Heating Choices for Landlords   With these new EPC standards, electric heating will play a huge role in helping properties meet compliance, particularly in flats, HMO’s and holiday lets.   Unlike centralised systems, standalone electric heaters such as electric radiators, panels and infrared units can heat individual rooms efficiently, converting 100% of energy into useable heat.  Two standout options: Ceramic Radiators: these are likely to shine as they heat up quickly and are also slow to cool since they deliver 50% of their heat via radiation.   Storage heaters: store energy overnight on cheaper tariffs and release it gradually throughout the day. An ideal heating option for properties where tenants are home during daytime hours.  Meet Ecostrad’s Magma HHR:   Ecostrad’s new Magma HHR is a next-generation high-heat retention (HHR) storage heater designed for comfort, efficiency, and compliance. Combining sleek design with advanced German technology, the superior insulation and precision to engineering ensures maximum efficiency and heat retention.  Using Magma Core Thermal Technology, featuring high-iron Ferolite bricks that retains heat and releases it gradually throughout the day. This means fewer units are needed for the same output, making installs faster, easier and more cost-effective for both landlords and contractors. Key Features and Benefits:   German engineered  High Heat-Retentive Ferolite Brick   WiFi Compatible   Dual or Single supply installation  10-year warranty on body and 2-Year Electrics   Boost Mode   Daily & Weekly Programming   Stay informed - stay ahead   As regulations evolve, we believe those who choose to stay informed will stay in demand. Electricians who understand EPC changes and energy-efficient technology will stay ahead of the curve.

We are now at a point where energy efficiency and sustainability are at the forefront of our minds. With rising energy prices, more homeowners are turning to renewable solutions to take control of their energy use. Beyond solar panels, Residential Energy Storage Systems (RESS) are emerging as a game changer, helping households cut costs, reduce grid reliance, and future-proof their properties.  In this guide, we’ll break down what residential energy storage is, the benefits it offers, and why SolaX Power’s innovative solutions stand out. If you’re an installer, you’ll also learn why choosing SolaX can give you a competitive edge.  What is Residential Energy Storage?  A Residential Energy Storage System (RESS)  is designed to store energy either generated on-site (like from solar panels) or from the grid, for later use. This means homeowners can access electricity even during power outages or peak demand hours.  A typical home solar battery storage system comprises:  Solar Panels: Generate electricity from sunlight (optional)  Battery : Stores the energy for later use.  Inverter: Converts direct current (DC) generated from solar panels and electricity stored in the battery to alternating current (AC) for household use.  Management System: Optimises energy usage and monitors system performance.  Benefits of Residential Energy Storage Systems   Benefits of Residential Energy Storage Systems   When recommending an RESS to customers, it’s worth highlighting the long-term advantages:   Energy Cost Savings:   With a battery, you can store the energy generated from solar panels or from the grid at cheaper, off-peak rates, which means you should reduce energy bills over time. For Electric Vehicle (EV) owners, an ESS can also serve as a charger.   In addition, most systems come with an energy management system, which monitors and helps you understand your energy consumption. You can identify inefficiencies, utilise off-peak energy tariffs, and develop smarter habits for when and how to use electricity.   Environmental Sustainability:   Having an ESS will reduce your overall carbon footprint. If solar panels are available, the battery will store renewable energy from that and makes it available when demand is there. With less reliance from the grid, households will effectively reduce demand for fossil fuel electricity and overtime, this leads to lower carbon emissions. It also demonstrates commitment to sustainability, which you can proudly share with family and friends!  Energy Independence: Allows homeowners to reduce their reliance on the grid and provides reliable backup power during power outages.     Increased Property Value: Homes equipped with RESS are often more appealing to buyers due to their lower operating costs and environmental benefits.  Why does this matter to you?  This growing demand is not just about convenience but preparing homes to actively participate in a more flexible, resilient and sustainable future. And as technology develops and adoption grows, these systems are poised to become a standard part of future-ready homes, making it an important area for professional electrical contractors to fully embrace.   Choosing the Right Residential Battery Storage Systems   When it comes to reliable and efficient energy storage, SolaX Power has built a strong reputation for reliability, innovation, and ease of use. With a commitment to innovation and sustainability, SolaX provides advanced solutions tailored to the needs of homes and small businesses. Their solutions are designed to maximise efficiency, reduce grid dependence, and give homeowners peace of mind.  Featured Battery Storage Products  X1-IES Residential ESS As Solax Power’s official distribution partner, we have the support and resources available for our customers looking for RESS.

Not enough Solar Panels (PV) leaves the battery empty and too much is just wasted energy and a higher installation cost. We are here to help determine your requirements and also offer a design service if needed. Q. How easy is it to add additional battery modules after the initial install?    A. This is always easy. All our inverters has simple battery options that can be installed and added on to in just a couple of hours by an approved installer. Q. What’s the typical install time for each of these package sizes?   A. Depends on the experience of the installer. SolaX systems are well-known for being fast to install.  Experienced installers can complete an X1-IES installation in under an hour. Minimal cabling, a stacking design, and straightforward instructions simplify the process. The whole installation - including the panels, roof mounting and an inverter, can typically be done in a day.   You can see here the process to install the X1 IES  https://www.youtube.com/watch?v=W0AKLCXpCu8   Q. Any key tips for installers to ensure the system runs at peak performance from day one?    A.

Whether it’s a public-facing install, a high-moisture environment, or a site exposed to daily wear and tear, sparkies know one thing: your accessories are only as good as the conditions allow . The right fixings and containment can make the difference between a tidy, compliant job that lasts — and one that fails under pressure.  We’re breaking down smarter ways to match your cable management solutions to the job at hand. Whether you’re dealing with wet walls, tricky substrates, or tight timelines, these featured products — and a bit of expert insight — will help you keep things neat, protected, and up to standard.  When it comes to outdoor installs, or any location where the elements such as water or dust is a risk, a basic junction box and standard glands just won’t cut it.  WISKA COMBI Junction Box, OneGel, SPRINT Cable Gland Featured Products:   WISKA’s COMBI 308 Junction Box  is an electrician’s favourite for exactly this reason. Built to withstand harsh conditions, it’s IP-rated and comes with threaded and cable entry membranes that make it quick to install.   Pair it with WISKA Cable Glands  and you’ve got a weatherproof solution that you can rely on whatever the elements throw at you. These glands suit almost any cable type and are vibration proof thanks to its unique thread pitch design. The glands can withstand high pressure and temperature spray downs at a close range too.   And if you’re working underground or in moisture-prone areas, WISKA OneGel  is your answer. This non-toxic, re-enterable gel provides extra insulation and long-lasting protection for cable connections — no drying, no waiting, no second-guessing.  From WISKA :  “One of the most common misuses we see is junction boxes installed without proper sealing — especially in outdoor environments. Over time, even a small amount of moisture can lead to failures. Our products are designed from real-world input from our customers and is constantly evolving to meet the demands of modern applications, from standard setups to highly specialised environments. This is why our COMBI Junction Box and Sprint Cable Glands stand out and have been industry game changers.”   Not all clips and mounts are created equal. In high-vibration areas or fast-paced installs, your fixings should be simple to fit, compliant, and built to stay put — no compromise. Whether you’re working on a large-scale industrial project or a tidy residential rewire, choosing the right clip makes a real difference to the quality and longevity of your work.  Walraven BritClips, Linian SuperClips and NanoClips Featured Products:   In busy industrial or commercial settings where speed and strength matter, Walraven BritClips  are a trusted solution. These heavy-duty fixings are designed for quick, tool-free installation directly onto steel structures — no welding, drilling, or fiddling about. Ideal for both permanent installs and even temporary setups, BritClips provide strength and flexibility without unnecessary complications.  From Walraven : “We often see installers trying to adapt brittle plastic fixings to steel structures or wasting time with overengineered solutions. Our market leading range of BritClips consists of over 100 fixings for multiple needs from beam clips with riveted combinations, to cable run clips for 2–20mm flanges, to master clamps and more.   BritClips are about smarter, safer mounting — no fuss. There are articles for different sized beams and purlins so whether you have a 2mm or a 20mm beam, we should have something to suit.”   Linian SuperClips  are a one-piece fixing built for speed, safety and value for money. With no screws or wall plugs needed, they’re installed in seconds: just drill, push, and go. Perfect for securing cables, conduit or even trunking to brick, concrete, or timber — and ideal for speeding up your install while staying compliant with the latest fire regulations.  Where installs call for clean finishes and minimal visual impact — think garden runs, exterior walls, or visible areas — the NanoClip  steps up. It’s compact, compliant, and a smart, non-combustible alternative to bulky clips or plastic ties.  From Linian:   “One of the most underrated features that makes a big difference? Single-component, fire-rated fixings. Our quality clips take consideration of the long-term performance as well as install time and are designed to meet the highest standard across the board.   Take the SuperClip  for example, perfect for larger cable runs or installations in high-vibration zones. Engineered with enhanced grip strength and rigid form factor that won’t loosen over time, keeping cables locked in securely.   For low voltage installations, the NanoClip  stands out as a smarter alternative to plastic cleats or cable ties. Neater, stronger and most importantly, non-combustible.”   If you’re installing in schools, offices, or retail spaces — anywhere public-facing — your trunking and conduit need to look the part, meet safety standards, and stand the test of time.  Univolt Dado Trunking and Heavy Gauge Rigid Conduit Featured Products:   That’s where Univolt’s Dado Trunking  comes in. With its sleek curved profile and multiple compartments, it neatly separates data, power, and telecoms cabling — helping to prevent interference and making installation and future maintenance a breeze thanks to clip-on fittings.  In demanding settings,  Univolt’s Heavy Gauge Rigid Conduit  should be your go-to. Designed for strength and flame resistance, it’s Lower Smoke & Fume (LSF) rated — meaning reduced smoke output and increased safety over standard PVC.  From Univolt : “There are many instances where data and power are crammed into one duct or run externally. It’s not just messy but is a compliance risk and can cause signal issues. Proper compartmentalisation is a must in modern installs.   There has also been a staggering interest and a sharp uptake in our PVC-LSF specified which is priced at no extra cost as standard PVC product. So really the question is, why wouldn’t you make the switch?”   Cables are only secure if their containment can carry the load, unless you enjoy the sound of cable trays crashing in the middle of the night. Trench Metal Cable Trays For high-capacity cable runs in industrial or commercial environments, Trench’s Metal Cable Tray  delivers reliability where it matters. With light, medium and heavy trays options available dependant on your requirements.  These trays are built to support cables securely while remaining easy to cut and mount. Trench trays are ideal for complex installations, high-rise wiring, or data centre layouts.  Need help choosing the right solution for your next job?  Whether you’re battling the elements on an outdoor install, navigating the demands of public-facing spaces, or simply aiming for a quicker, tidier job — the right cable accessories make all the difference.
