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.

Hi Mahendra,
Thank you so much for the fantastic review and for sticking with us these past few years — it really means a lot. It’s great to hear you’ve been happy with both the system and the support from our team. You're absolutely right — these systems do take a bit of learning at first, but once they're dialled in, they should run like clockwork.
We’ll make sure Mark sees your kind words — he takes pride in being thorough and dependable, and it’s clear that shines through.
Thanks again for your trust and continued support. We’re not going anywhere — and we're always here if you need us.

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 👌👍🏻

Hi Ms. Cocker,
Thank you so much for taking the time to leave us such a detailed and thoughtful review – it really means a lot to our team. I’m especially glad you mentioned that we’ve been able to keep your older air‑source heat pump running smoothly. Those early generation units can be a bit quirky, and, as you’ve experienced, not every company has the confidence or experience to work on them. We’ve been working with renewable heating systems since their early days, so our engineers have been around the block (and back) with just about every make and model. That depth of knowledge is what allows us to walk in confidently and keep older kit ticking along efficiently when others might throw in the towel.
We also know that punctuality and reliability aren’t optional extras – they’re the basics of good service. In our experience, regular servicing on an aging unit is not just a box‑ticking exercise; it genuinely extends the life of the hardware and keeps it performing as efficiently as possible. That’s why we take a thorough, consultative approach to maintenance rather than just giving it a quick once‑over.
If you ever have questions about the system’s performance, or if you’re curious about whether future upgrades could save you money in the long run, feel free to give us a call. We’re always happy to chat through options and help you plan ahead rather than reacting when something breaks down.
Thanks again for the recommendation – it’s the highest compliment we can receive. We look forward to keeping your air‑source heat pump humming along for many more years.
Warm regards,
The team at EPC
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.

Thanks so much for the fantastic review, John!
It means a lot coming from someone as experienced in the self-build space as you are. We know how much is riding on getting the renewable element right for your clients — so we always aim to bring the same level of care and precision whether we’re advising on system design, getting installs done on time, or being available for post-install queries.
We’re genuinely thrilled that our approach has delivered value for your clients and earned your confidence. Thanks again for the recommendation — we really appreciate it.
All the best,

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.

Hi Andrei,
Thank you for taking the time to leave such a detailed review. We’re genuinely sorry to read how frustrated and distressed this situation has been for you and your family.
This is a complex and ongoing matter, and we want to be clear that we are currently engaging directly with you to review the concerns you’ve raised, including system performance, design assumptions, and the supporting data you’ve provided. We are taking the issues seriously and are working through how this can be addressed constructively and properly.
Given the technical and contractual nature of the points involved, it would not be appropriate or helpful to debate them in a public forum. Our focus is on reviewing everything in detail and working towards a practical way forward through direct communication with you.
We appreciate your patience while this review is ongoing and remain committed to engaging with you in good faith to reach a fair resolution.
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!

Hello Angus
As this matter is subject to legal proceedings, we are limited in how much detail we can publicly share. However, we feel it’s important to address some of the claims made here.
We strongly refute your suggestion that we acted unlawfully or unfairly. At every stage, our pricing, terms, and scope of work were made clear and agreed upon in writing. Any additional charges discussed were the result of changes or extras requested after the original agreement — not hidden fees or arbitrary demands.
Our team invested a significant amount of time supporting you throughout the process, always in good faith and with professionalism. We made every effort to ensure the project met your expectations.
As a fully accredited member of RECC, we take compliance and transparency seriously. The accusation that we “broke the law” is simply not accurate, and we stand by the integrity of our process — including our right to recover legitimate costs when due.
We also noted that every review you've left on Trustpilot is a 1-star rating. That pattern does raise the question of whether this review genuinely reflects our service or is part of a broader habit of public complaint.
While we respect the right to leave honest feedback, we will not accept false or misleading accusations.
Kind regards,
Team EPC
