5.0

Insight Energy Systems Ltd is described by reviewers as professional and well organised. Andy is named by several reviewers as knowledgeable, meticulous and honest about what can be achieved with an air source heat pump installation, one of whom said he did the calculations and came up with a good plan. A full underfloor heating system with an air source heat pump left one reviewer very pleased with the result, and another said the system is now running brilliantly. One reviewer said the place was left clean and tidy and that Andy went over and above to make sure suppliers sorted out an early manufacturing issue; another mentioned guidance from start to finish. One reviewer noted that Andy was professional and technically aware during a home visit and that a boiler service was also completed professionally.

Looking at reducing my energy bill’s and interested in heat pumps as an alternative to a gas boiler, I contacted a Insight Energy Systems, who are local to me to request a home visit. Andy was very professional, knowledgable and technically very aware!. After a full inspection of the house, the suggested specification of a heat pump with a PV roof system seemed very sensible. Having underfloor heating in some rooms helps, although in other rooms, radiators will need changing. Andy also communicated regards government incentives available. Would totally recommend IES, if you are looking to change your heating system to a renewable technology. Update: Boiler service completed. Once again very professional.

Full underfloor heating system with air source heat pump. Very pleased with the result, almost can't wait for winter to turn up the heating! Andy and his team were very professional, reliable and knowledgeable and hardworking.
