“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.

“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.”
