“We've had our heatpump for 15 months and are delighted with it. We recently had our first service, completed by Mark, and as with all our other interactions with EPC staff we found him polite, professional, and full of useful information to help us get the best from our heat pump. Highly recommend.”

“Faulty battery and complete unwillingness to resolve the issue. I waited weeks for an engineer to come out to fix the battery which has not been working for months. He said it was a dud and needed replacement. EPC have done nothing about this for a week and when I said I wanted a different brand of battery or a refund they ignored me and started saying it was my fault. They refuse to take responsibility and push back on the customer every time. An awful company i cannot recommend. Email below where he lies about why my battery isn’t working and ignores my requests and tells me I have to do what they say..”

Thanks for your feedback, though we’re obviously disappointed to read your interpretation of the situation. We want to be absolutely clear: we’ve made every reasonable effort to support you throughout this process—from the initial installation, through to the most recent engineering visit, and now as we work with the battery manufacturer to get the issue resolved. At no point have we dismissed your concerns; in fact, our engineer attended site promptly and identified the issue, which we’ve been actively escalating. As mentioned in the email you’ve shared, the battery was not operational due to it being powered down—a fact confirmed during our April visit. We're not interested in finger-pointing, but it's important to clarify this detail, as it's key to understanding the timeline. While we appreciate that this situation has been frustrating, resorting to personal attacks and publicly accusing our team of dishonesty—when we’ve been working to resolve a third-party product issue—is not a constructive way forward. We stand by our team’s professionalism and commitment to customer support.

“I am no kind of expert about Heat Pump systems or roof top solar panel systems, the former installed by EPC in August 2020, the latter installed in 2010 and now incorporated into EPC's care and management. The annual Service of the Heat Pump system seemed to me to be very meticulously carried out by Mark on a system that in recent years has been working very well for me as the system user. Very reassuring, and many thanks to Mark and the EPC Team.”

“Excellent service by this company! Mark communicated well and advised on issues, sorted out some minor issues which was done by installation team, which I believe was not this company! After the service and works carried out he explained on how to improve on energy efficiency and explained the mechanics of the system again in simple terms! Very pleased.”

“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.”
