“EPC guided us through the entire complicated process of switching from gas to heat pump heating system. Not a straightforward job in an older 3 story building. Global pandemics, supply chain problems , liaising with the government schems and local authority regulations – all negotiated with professionalism and experience. The installation itself was another deeply impressive demonstration of technical ability and determination to make it perfect. Several years of trouble free heating since, their attention to ongoing support and advice has been invaluable. Cannot recommend them highly enough.”

Thanks so much, Matthew! Really glad we could help you make the switch from gas to a heat pump—especially in a tricky older building during a pretty chaotic time. Between the pandemic, supply delays, and navigating the regulations, it was definitely a team effort. Brilliant to hear it’s been running smoothly all these years. Delivering reliable, low-carbon heating and ongoing support is exactly what we’re about. Appreciate the recommendation! Please feel free to refer us to friends and family—our company is built on recommendations.

“I have had a heat pump for some years now and it has always worked perfectly. People complain my house is too hot! It is recommended the system is serviced periodically to service the pump and pressure. I always have had pleasant and helpful people receiving my calls. On this occasion James came to carry out the service. James is professional and considerably trained and experienced in heat pump installation and servicing. I wouldn’t hesitate and am confident to recommend EPC to provide reliable heat pumps ,to carry out installation and servicing.”

“Mark Lawrie came to carry out the annual service of our heat-pump system, and gave us good advice. He also discovered a leak that we hadn't known about and would have caused serious problems if left.”

Thank you for the brilliant 5 star review, Ranulph, we really appreciate it. Great to hear Mark looked after you and provided solid advice during the annual service. That’s exactly why these checks matter. Spotting a leak early before it turns into a major issue can save a lot of stress and unnecessary cost down the line. We take servicing seriously because it’s not just about ticking a box, it’s about protecting your system, your home and your investment. I’ll make sure your comments are passed on to Mark, he’ll be pleased to hear them. Thanks again for trusting EPC with your heat pump system, and if anyone you know is considering renewables or needs ongoing support, we’d be glad to help.

Thank you for the fantastic 5 star review, Roberto. It’s great to hear you’ve had Mark back again and that he’s continuing to deliver the level of service we expect. Taking the time to explain things properly and answer questions clearly is a big part of what we do. Renewable systems can be technical, and you should never feel left guessing. We’re also really pleased to hear the system is performing well, energy costs are where they should be, and most importantly, that the house feels consistently warm. That’s exactly the outcome we design for. I’ll pass your comments on to Mark, he’ll appreciate it. Thanks again for your continued trust in EPC.

“I've gone through the online reviews,and noticed that negative reviews get no reply. My experience with EPC was very impressed with my instalation of solar panels was that they preformed th insatations to a high level of workmanship. But my latest instalation which at a later date incuded 10 kw of battery storeage,has not been very pleasant, since June 25 I've had no storeage due to a faulty Dongle so the system is useless .Between Give energy and ECP they dont appear to be able to rectifie the problem and dont appear to wont to resolve the problem,as they both have had there monies but are forgeting the cusomer relationship . I would sreer clear .”

“EPC installed our Heat Pump system in 2019, and have managed the servicing each year since. I have always been very happy with the level of customer service received, and yesterday was no exception. We had a brief power cut and our thermostat lost connection with our boiler. I tried a few things, but with no luck I called EPC for some advice. Within 5 minutes James the Technical Manager had called me back with some ideas, and then emailed me through an instruction booklet to follow. I was then able to resolve the issue and get the heating back on. Very happy customer, and I would recommend EPC to anyone.”

Thank you for the brilliant 5 star review, Tom. It means a lot that you’ve trusted us with your heat pump system since 2019 and that the service has remained consistent year after year. That’s exactly how it should be. Power cuts can throw systems out, and it’s frustrating when heating drops out. I’m pleased James was able to jump on it quickly, talk it through with you and send the right information so you could get everything back up and running without delay. That’s the level of support we aim to provide, responsive, practical and solutions focused. Thanks as well for the recommendation. Long term relationships like this are what EPC is built on. If you ever need anything, you know where we are.

“I am still learning from the experience of having a heat pump as my mode of heating and it is early days. However, the service provided in arranging the installation has been fairly smooth and as stressfree as my own concerns would allow. I have found all the staff whether office or technical to be most helpful, courteous and competent with any queries swiftly resolved. Future service needs have been arranged and I look forward to a good and happy relationship with the company. Thank you EPC Improvements”

Hi Allan, Thank you for your kind words — we’re genuinely pleased to hear the experience has been smooth and supportive overall, especially as you get to grips with your new heat pump. It’s a big shift, and we’re here for the whole journey. That said… we’ll admit we’re scratching our heads just a little at the 4 stars! 😅 This wasn’t just a standard install — we mounted the unit on the wall, added fan-assisted radiators and plinth heaters to get the comfort levels just right. Our admin team even paused their work and had a coffee with you when you popped in on your bike — it really felt like a team effort on both sides. Jokes aside, we’re proud of the care and attention our entire crew gave this project, and we’re thrilled to have built a relationship that you’re happy to continue. We look forward to supporting you long into the future. Thanks again for choosing EPC Improvements. Warm regards, The EPC Team

“It’s taken me nearly two years to write this review—not because I wasn’t frustrated or upset sooner, but because I wanted to gather accurate, comprehensive evidence before passing judgment. I contracted EPC Improvements to install a Samsung air source heat pump as part of my effort to transition away from gas for environmental and economic reasons. What I received was a system that consistently underperforms, costing far more to run than promised and operating at a measured SCOP of 2.23—a far cry from the 3.92 figure EPC projected or the 3.01 minimum SCOP Samsung claim is achievable even at 65°C. The heat pump consumes roughly 75% of our household electricity, invalidating the environmental and financial justification to switch. EPC’s response has been to deflect, delay, and ultimately deny responsibility, even misrepresenting data collected by the Samsung-provided monitoring system used to assess the unit’s performance. One of the worst aspects of this experience was a serious safety hazard that EPC left unresolved. A radiator installed using incorrect fixings became increasingly unstable. I flagged this issue multiple times—in November 2023, March 2024, and April 2024—yet EPC only responded on 28th June, after a four-month silence. Tragically, I missed their email, and the radiator fell on 30th July, injuring my three-year-old daughter and causing her ongoing pain and distress for months. Over a year later, that radiator remains zip-tied to a wooden block in my home. I’ve had to go to extraordinary lengths to move this forward. I commissioned one of the UK’s top heating engineers—the individual who wrote the very material used to train Heat Geek engineers (a certification EPC once held before being removed from their approved list). His report confirms what I had feared: the buffer is the wrong type, the primary pump is for gas boilers, not heat pumps, glycol was incorrectly used, and every radiator is undersized. It's no wonder the system struggles. To EPC’s credit, their on-site workmanship (pipework and connections) was praised by the expert as high quality. But sadly, good pipe soldering doesn’t compensate for poor system design, unsafe installations, or inadequate customer care. A Message to EPC: The expert I hired was willing to advise you directly on what’s needed to fix this, but based on how poorly you’ve handled things so far, I had no faith that you’d listen. That offer still stands, should you decide to change course. The basic remedial actions required include: • Replacing the buffer with a properly designed volumizer • Swapping the Grundfos UPS3 pump (a gas boiler pump) for a UPM4XL designed for heat pumps • Removing all glycol and using proper anti-freeze pumps • Re-evaluating and resizing all radiators • And potentially checking whether the heat pump itself is faulty, given its repeated early failures and current performance Final Thoughts: What disheartens me most isn’t just the technical failings of the system, but the attitude EPC have shown throughout—a refusal to engage constructively, misleading explanations, and a total lack of accountability for an installation that has physically harmed a child and continues to financially and environmentally underdeliver. If you're considering a heat pump and value safety, honesty, and post-installation support, look elsewhere. Given Samsung’s limited interest and support during this ordeal, I also strongly suggest choosing a brand like Vaillant, whose performance and installer networks seem far more robust.”
