Work was carried out to a very high standard in accordance with specialist requirements which involved changes to central heating and hot water systems including the installation of a new boiler. His attention to detail was demonstrated by the quality of the soldered joints which area result of years of experience. David was very knowledgeable, friendly, polite and kept his workplace tidy. We were kept fully informed on progress. The price to carryout the work was as quoted and where additional unforeseen works undertaken, David advised us the likely extra cost before undertaking the agreed work. We have already booked David to come back to service the central heating and have no reservations in recommending his services.
