“well what can I say that nobody else hasn't apart from EPC is a company who employs engineers who knows the inside out of all heat pumps and how they actually work and not just on paper but in practice too. Mark is an easy guy to listen and talk to and has a lot of patience having to go through things more than once so you're fully understand the concept. thanks Mark.”

“Mark provided excellent customer service when quoting for our (quite complicated) PV system. He was always quick to reply, took to a lot of time to provide a system that best met our requirements and cleasrly has a deep understanding of the technology and processes involved. I'm looking forward to working with the installation team and seeing our system going in soon. EPC Improvements were recomended by a contractor that has very high standards, and now I know why.”

Thank you so much for the great feedback! We're thrilled to hear Mark was able to guide you through the quoting process for your PV system—especially given the complexity. His technical depth and dedication to tailoring the right solution really shine in situations like this. It’s fantastic to know we were recommended by a contractor you trust, and we’re excited to carry that standard through to the installation phase. We can’t wait to get your system up and running! And if you’re happy to pass our name on to others, we’d be truly grateful. Our business continues to grow thanks to referrals from customers and professionals who value quality and care.

“Very thorough annual heat pump service. Engineer explained matters as he went along and was very willing to answer questions with full explanations. Never felt that he was rushing to leave because of other appointments. Even before he did leave he asked if we had any other questions or queries.”

“Had huge issues with them - broke my roof, sold me mis-specced items, then tried to extort me for more money on top of what we agreed. Literally having to take them to court. AVOID!”

“Excellent service. I had a problem last year for which EPC were able to help me out although the system had been installed by another company. I'n just had my first service by EPC and am very happy with the the whole process. Mark came yesterday, completed the job, made a couple of recommendations and left me feeling content.”

“I've had my heat pump installed for about 2 years now and initially had some minor problems but they were soon sorted by James at EPC. The install was very swift despite being not an easy one and the installers were very tidy and did a neat job lagging and hiding the extra pipes needed. I've been over the moon with my decision to both install a heat pump and to have chosen EPC to do the install. Over the winter period the whole house is warm and cosy without costing me a fortune. Mark from EPC has just completed an annual service for me, it's good value for money if you pay by monthly installments, he did a great job explaining what he was doing and why. Mark also went over and above what I've experienced from British Gas with my old gas boiler in improving things further with advice on insulation of my install, as it's in an unheated garage, he also went outside and put extra insulation in places which is something he didn't have to do but I really do admire his tenacity in wanting my install to be just perfect. I've been talking to and showing my neighbour my install as they want a heat pump as well and I highly recommend EPC to them.”

“I arranged a service for our heat pump and the appointment was made within days. I asked for the engineer, Mark to call at an approximate time and he arrived as requested. He was friendly and very professional and thorough. He checked and services the heating system and all the radiators to ensure everything was functioning properly. I was pleased with the company's friendly and professional working practices and I will be happy to continue to use their services.”

“Have had a poor experience. Communication not great. Had to complain twice. Sent an email last week asking for job to be finished. This and subsequent email has been ignored. They did not come on the day they said and when they came later they couldn’t access the pipes to finish the job. The engineer said he would come back the following week but no one is responding to emails. It’s a shame as much of their work is good but I don’t think they understand how complicated the project is and that they need to be clearer about what is required and stick to their deadlines. If things change they need to explain what access they need and not rely on the small print of an email sent 6 weeks previously. Just because they do this all the time doesn’t mean customers know or can remember every detail.”

“A truly dreadful experience. What went wrong? Everything but the in-house design (which was okay) was subcontracted so nothing was seemingly EPC's responsibility - someone else. The in-house engineer/plumber was incompetent. The subcontractor installed the heat pump plumbing wrongly, then the commissioning results and commissioning certificate were fiddled to make everything seem okay. The reality was that the heating system was incapable of being commissioned: radiators never exceeded 33C - hopeless. And it took months for EPC to accept responsibility. The PV installation never happened after 7 months and we had to go elsewhere. Then EPC kept the deposit... EPC backed away from their guarantees and in any case we do not want their service as maintainers: we have no confidence in the company. However, EPC was remarkably prompt in collecting the BUS grant, which they keep! Never a hint of an apology... I could say a lot more...”

“The system was not installed as per the contractually agreed design. The design was changed on the fly by the installers who claimed to have never seen the design”
