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

Excellent & Informative experience
Marc, was excellent in reviewing our requirements for the hot water and heating system at our new build house. He gave good recommendations with all the requested supporting details and estimates. Very attentive and supporting throughout.

Thanks very much, Eamonn — really appreciate the feedback.
Marc takes a lot of pride in properly understanding a project before making recommendations, especially on new builds where getting the system right first time really matters. It’s great to hear you found the advice clear, detailed, and well supported.
Thanks again for trusting us with your new home. We’re always here if you need anything as the build progresses.
Best in the business
A previous company bodged the installation of an air source heat pump with underfloor heating throughout my house and it was replete with issues.
After a year of back and forth with this other company, I asked James from EPC improvements to do an independent review of the installation. He identified all the faults and proposed a remediation plan. After one day's work, everything works perfectly - the flow rate is optimised so it runs quietly, I can control all my temperature zones from an app, the pressure is at target, the configuration is correct.
I'm incredibly relieved to have found James and EPC improvements. James has been installing heat pumps for two decades and his knowledge is top shelf. If you are considering an installation, or facing issues with a previous company, EPC improvements are peerless.

Thanks so much, Jared — that really means a lot.
Unfortunately, we see situations like this more often than we’d like, and it’s exactly why we take such a methodical, engineering-first approach. I’m glad James and Mark were able to get to the root of the issues quickly and put a proper remediation plan in place — and even better that everything is now running quietly, efficiently, and exactly as it should.
Your comments about James’s experience and attention to detail genuinely matter to us. If anyone’s on the fence about a heat pump install or dealing with problems left behind by others, we’re always happy to give honest, independent advice.
Thanks again for the trust and the recommendation.

Thanks, Mr Cook — we appreciate you taking the time to leave a review.
Doing exactly what we say we’ll do, when we say we’ll do it, is the baseline for us, so it’s good to hear that came across on the day. I’ll be sure to pass on your comments to the engineer as well.
Thanks again for choosing EPC Improvements.
EPC Annual Service
The Engineer, Mark, was friendly and efficient in servicing the system - explaining what he was doing and what to do to avoid a blocked drain from leaves in the ASHP.

Thanks, Simon — really appreciate you leaving a review.
Mark is great at making sure customers understand not just what’s been done, but how to keep the system running smoothly long term, so it’s good to hear that came through. Simple things like keeping drains clear can make a big difference to performance and reliability.
Thanks again for booking your annual service with EPC Improvements — we’re here whenever you need us.
Excellent Customer Service
Just wanted to say a big thank you to the team at EPC for arranging one of their technicians/fitters to come out to look at our battery and get it back online.
The guy that came was amazing and so helpful and polite and we are back up and running.
Just wanted to make sure I passed on this feedback. People often only get in touch to complain, but feel it is just as important to notice the good points.
We are very grateful for you and your team with our whole solar and battery journey and your professional support from start to finish. It has been exemplary and we cannot fault you!

Getting systems back online quickly and properly is exactly what we’re here for, and it’s great to hear the technician looked after you so well. I’ll make sure your feedback is passed on to the whole team — comments like this genuinely matter.
You’re absolutely right that people tend to speak up when things go wrong, so we’re especially grateful you called out the positives. Thanks again for trusting EPC with your solar and battery setup — we’re glad to be part of the journey and we’re always here if you need us.

Service of heat pump
Mark was very thorough and gave us clear easy to understand explanations.
He was also thoughtful with the bad weather and took precautions to leave it outside

Hi Nickie, thank you for taking the time to leave such a thoughtful review. We’re really pleased to hear that Mark explained everything clearly and took extra care given the bad weather — that attention to detail is exactly what we expect from our team. We appreciate the recommendation and are glad you were happy with the service. If you ever need anything in the future, don’t hesitate to get in touch.

Mark, didn’t just service the heat pump. He also checked the hot water system and the underfloor heating. Spotting issues with both, that he spent additional time fixing.

Hi Kieron, thanks very much for the great feedback. Mark takes real pride in going beyond a basic service, so it’s good to hear he picked up on the hot water and underfloor heating issues and got them sorted for you.

Terrible experience
Terrible experience. Arrogant company.
Found EPC through a facebook advert. Was very impressed at first and decided to go with them to fit a heat pump for our refurbishment project. I promptly paid the deposit and was sent proforma information from vaillant and a list of things that needed to be done prior to the install. We had a contact who was very responsive but never told me that we basically needed to complete everything, (which amounted to second fix for our plumber and electrician) give them photos proving this, and then wait 8-10 weeks before they can come to do the installation. This lead time is a crucial piece of information. Turns our contact left EPC while were mid preparation stage, but I was never told. I only found this out when my emails had gone unanswered and i called the company to find out why. I was then told about the crazy long lead time, which would have meant us moving into our house in winter with two small very small kids and no heating or hot water for several weeks. There was very little concern for this, no apology for the lack of communication and even at that point they wouldn’t even pencil in a date because they wanted everything completely finished for the installation first - which was completely unrealistic.
I told my plumber about this, who said it was crazy and recommended another company who could come and do the installation in time for us. The documents i had signed with EPC at the time of paying the deposit made it clear I could cancel and get the deposit back less some minor deductions. So i notified them of this, and then suddenly EPC became more responsive. But it was too late. All confidence had gone and I saw no reason to proceed when we had a clear better alternative that was not going to put my family at risk of having no heating or hot water.
However I am still waiting for the deposit to be returned after two months. They clearly have no intention of doing so. I am now having to prepare a small claims court application.
Also, having gone with another company I now look back on what EPC told me at the preparation stage and don’t think it wasn’t great. Wish I had been with the other company from the start.
Beware.

Thank you for taking the time to set out your concerns. We are sorry that your experience did not meet your expectations and appreciate the opportunity to clarify the situation.
At the outset of the project, EPC provided an installation timeframe that was fully in line with our standard process and industry norms for heat pump installations of this type. This timeframe was contingent on all prerequisite works being completed and signed off, which was clearly outlined in the documentation provided at deposit stage. An installation date was available within the agreed timeframes once the project was ready to proceed.
We acknowledge that your original point of contact left the business during your preparation phase. While the project itself remained active and managed internally, we accept that this change should have been communicated more clearly and we apologise for the frustration this caused.
Regarding the deposit, EPC is not withholding it in full. As set out in the terms you signed, the deposit is refundable subject to deductions for costs already incurred. By the time cancellation was received, the project had progressed to an advanced pre-installation stage, including system design, specification, manufacturer coordination, administrative processing, and resource allocation. These costs are material, not minor, and are currently being itemised in line with the contract.
We also apologise that the refund process has taken longer than expected. This period coincided with our busiest operational window of the year, and we experienced unforeseen staff absences due to sickness. That said, we recognise this does not change your expectations, and the matter is now being actively progressed.
A director of EPC will be in direct contact with you to finalise the refund calculation and bring this to a conclusion. Our intention has always been to resolve this fairly and in accordance with the agreement, not to delay or avoid repayment.
While we regret that you chose not to proceed with EPC, we wish you well with your installation and trust the above clarifies our position.
professional, expert, helpful
We installed a Vaillant heat pump with EPC two years ago. Every aspect of the installation was dealt with with a professional and competent manner: the installation was top notch (not a single problem across two years); on the handful of occasions we needed help with the controls EPC staff were very helpful and sorted our problem quickly and efficiently. The heat pump has been working seamlessly.
There are two points worth special mention. First, in trying to decide whether to install a heat pump or not, EPC staff did not do a hard sell: they tried hard to offer us objective advice, to help us make the right decision for our household. It is worth pointing out that, as we are one of the first households in the area to install a heat pump, we had a lot of trouble getting approval from the local building authority (the regs have changed now, but basically at the time we needed planning permission because of the volume of the pump). EPC were fantastic helping us navigate a fairly complex and unpleasant exchange with planners. The second point is that we needed the heatpump positioned on top of our garage, on the side of the house (we live in a semi detached house). This was hardly trivial -- the machine is about 200 kg. The EPC installer was brilliant, using a winch to lift it over. It felt a bit like pulling a rabbit out of a hat, moving the machine where it needed to be.
We have been using EPC for the annual heat pump service. Also, we are looking to bring them back to install solar panels to our home. Definitely extremely happy with everything they did; we highly recommend them.

Hi Emmanuel, thank you for such a detailed and thoughtful review — feedback like this really means a great deal to the whole team.
We’re especially pleased to hear that the system has performed flawlessly over the past two years and that our support around controls and servicing has been prompt and helpful. Your comments about the decision-making process are important to us — we’ve always believed that heat pumps aren’t a one-size-fits-all solution, so giving clear, honest advice without pressure is the right approach.
The planning process at the time was far from straightforward, and we’re glad we could take some of that burden off your shoulders and help steer things through. As for the garage install — you’re absolutely right, that was no small task, and it’s great to hear the ingenuity and care of the installation stood out.
We really appreciate your continued trust in us for servicing, and we’d be delighted to help with your solar installation when the time comes. Thank you again for the recommendation — it means a lot to us.
Good service and an efficient heating system
EPC designed and installed the system we have which is somewhat different to standard UK installs. EPC continue to provide an annual service which is comprehensive and thorough. Both James and Mark are always ready to answer any questions.

Hi Elizabeth, thank you for taking the time to leave such a kind review. It’s great to hear that the system design and installation have continued to perform well, especially given it’s a more bespoke setup. We take a lot of care with non-standard systems, so it’s good to know that shows through in both performance and servicing. James and Mark will really appreciate the mention. As always, we’re here if you have any questions or need support in the future.
Professional and Friendly
