Breath of fresh air, great engineer, explained everything and fully serviced the Heat pump. Clean, tidy, thorough and very helpful.

It was good to see Mark again doing the annual service of my Heat Pump system. I have no relevant expertise in Heat Pump systems. But I trust that Mark did do an excellent job.

Highly recommend EPC Improvements
Highly recommend EPC Improvements, we’ve not yet got to install stage but Marc who was our first point of contact has helped us spec the right system for our needs, answered my endless queries, and provided all the information we need to pass on to our contractor. There is no over speccing, he and the company are about providing optimal performance-I’m looking forward to the next stages!

EPC installed my Air source heat pump and solar panels and battery about 3 years ago. As expected, took a little while to get used to the system and to dial in the settings. But over this period, whenever I have had an issue, they have responded and supported me. Good to see the company still going strong after so many horror stories of installers disappearing in the night. Mark who is our regular service guy is careful and knowledgeable and dependable.

Professional, knowledgeable & reliable ⭐
Always on time, professional and knowledgable; which is especially handy as we have quite an old ‘Air source Heat Pump’ which a lot of companies do not have the knowledge to offer support and maintenance on (we learnt this the hard way a couple of years back). Their combined expertise has kept our Airsource solution working so would definitely recommend 👌👍🏻

Experts in Self build advice
EPC have looked after and carried out renewable installations for several of my self build clients. They have been thorough with their reviewing projects, advice and installation designs and actual installs have been carried out efficiently, on programme and to an excellent standard. Their after install service is also excellent always on hand should any problems or queries arise. They are very professional in their approach to each project and I would have no hesitation in recommending them to future Clients.

Reliable, knowledgeable and responsive
It is good to get the same contact at EPC each time. I have been talking with Marc for several years now. He is very knowledge of the systems EPC create and is always willing to discuss and modify the details.

Valuable Guidance for Our Commercial Energy Upgrade
EPC provided great feedback on fitting solar and heat pumps to our commercial property. Their advice was honest and balanced giving us the ability to determine the most cost effective route forward. I would highly recommend.

Heat pump servicing
I arranged a service for our heat pump, this was booked with an engineer efficiently. The engineer was friendly and very professional and thorough. He checked the while system and radiators to ensure it was all working correctly. Very pleased with the Company’s friendly and professional working and will continue using them in the future.

Five Star Company - Solar Panel & Battery Install
Installed a solar panel system and battery at my property in September 2024. I cannot fault the communication and attention to detail EPC Improvements provided from start to finish.
I have had other trades people carrying out work at my property and I only wish they exercised the same level of care, expertise and attention EPC Improvements provided me with throughout my project.
I have recommended this company to all my friends and family.

EPC Improvements – A Deeply Regrettable Experience
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 causing distortion and a loss of 10c, which in low temperature system is fatal, the primary pumps are not the correct size, glycol was incorrectly used, and every radiator is undersized. My total shortfall is around 50%.
To EPC’s credit, their on-site workmanship (pipework and connections) was praised by the expert as high quality. But sadly, good pipe 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 pumps for 25-120 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. Given that experience, I can only imagine how much I was overcharged for the heat pump.

Mistakes and extortion - WE DID NOTHING WRONG!
Everything started okay, but by the end of the process this company demanded extra money from us over and above what we had agreed to! And then threatened with court action - they literally broke the law (Consumer Rights Act), but won't accept responsiblity. Even have to report them to RECC - AVOID!
