Reviews

4.6

Reviewers often report air source heat pump installation by EPC Improvements LTD, with several saying the work was tidy and professionally done. Many reviews describe servicing visits, with the engineer explaining the system and answering questions. One reviewer said the solar panels and battery work was not followed up well, and that solar panels were installed incorrectly and a battery failed. One reviewer said two inverters failed, that faulty workmanship caused a fire, and that the business was reluctant to respond or offer compensation. Another reviewer said the business did not finish their solar, underfloor heating and heat pump job, and one said a thermostat and controls subcontractor did not enable online control.

We investigated using EPC for replacing a hot water cylinder, servicing our ASHPs and to install a large solar PV array. We were impressed with how EPC responded to our many questions and demonstrated that they really knew their stuff when it comes to ASHP heating and solar. Once we agreed to go ahead with the works, the EPC team were well organised and communicated well at every stage of the process. Every one of the large team of specialists that we interacted with were excellent, from Craig the co-owner to the project managers to the electricians to the third parties they work closely with. Each time a new phase of the works was completed the working areas were left tidy and every one of the team we met behaved very professionally and put in some long days. They really were keen to do a great job - and they did. I have no hesitation in recommending EPC Improvements.

Fantastic service from start to finish. Marc provided great insight to the different options available prior to me making a decision on the heat pump. Danny was great, keeping close contact and ensuring that i knew when everything was taking place. Nathan and the team whom performed the install were exceptional. Answered all the questions through the process with details explanations on the different aspects. Worked really hard everyday and left everything as you would wish for. Great all round.

Installation team turned up on time and immediately got to work installing the 10Kv battery pack in chosen location. They knew where all elements of my system were installed and explained where they would be installing cable run and whether acceptable. Workmanship was fantastic even to the smallest details, like using two different color cable trunks to match cover of battery box. He explained what had been done then asked if I had any questions. He took me through app on my phone which was updated with the new system elements and guided me through the options. Excellent service
