We were looking for an alternative to our oil fired heating, which was getting very costly to run, but were unaware as to what the alternatives were. That was until we were referred to Mark Roper who explained everything in detail without any sales pressure at all. We felt we could trust his advice and went ahead with a pv panel installation and a heat source pump for our central heating. Our fuel costs are now much lower and any sign of an oil fired installation has gone! From start to finish the installers were very professional and clearly skilled at what they did. We would have no hesitation at recommending Mark and his company to any interested clients.
