EPC Improvements Ltd

I asked EPC to help me understand if an ASHP would benefit me, as I searched for an alternative to a standard gas boiler. This started with a survey to see what the heat requirements were and to see what would work. The intro meeting was very informative and all my questions were answered by the very knowledgeable engineer. I then received quotes for the works which I asked them to proceed with. We had a few false starts due to equipment delivery problems (thanks to covid) but once started the implementation was completed in a week. The implementation by Ben and Scott was very neat and I was impressed with their work ethic and attention to detail. Now its all finished and even though it -7 outside I have a nice Green solution for heating and hot water and a warm house. I would recommend EPC for anyone considering an ASHP

I can recommend EPC improvements whose sales team, project managers and admin support staff are informative and enthusiastic in all they do. This company engaged an installation team who worked quickly and tidily and were a pleasure to have around the house. Ours is a large open plan but well insulated, modern house benefitting from underfloor heating throughout and therefore ideal for the installation of an Air Source Heat Pump therefore the decision to replace our oil boiler was not hard make. The Steibel Eltron unit is easy on the eye and whisper quiet when running. There were some minor teething problems interfacing the new unit with our existing heating control system all of which were dealt with speedily and efficiently by EPC. We now await the onset of winter to really test the systems ability to keep us warm and well supplied with hot water

EPC have been very patient with us and kept us updated and guided us through the whole process. They were also flexible with our needs. Completed work was very professional. Highly recommend.

Excellent communication and help. I would not hesitate to recommend this company.

I can thoroughly recommend EPC Improvements, they were supportive during every phase of the process, from planning to installation. No question was too much trouble and any suggestion or query from me about the installation was discussed and satisfactorily actioned. Following the necessary survey it was found that all my radiators needed to be replaced, and this was achieved with the minimum of disruption. Due to local problem with falling leaves in the Autumn and Winter I requested that the actual heat pump be mounted on a side wall. This was no problem and really neat and tidy installation was achieved. On the whole a first class organisation the work with and I am really impressed with the end result.

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 writing this review. 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. In addition to the heat pump, I had also contracted EPC Improvements to install a large solar panel and battery system for a total quoted cost of £25,274, bringing the combined value of both installations to just under £50,000. Needless to say, I cancelled the solar installation, forfeiting the insurance fee, and instead went with a different installer. This turned out to be the best decision: I received double the number of panels, a higher-quality European bifacial brand, and battery for the same price.
