“Liked David's experience & credentials so asked him to quote for a boiler replacement, multiple radiator replacements, systems upgrade etc, due to poor heating. Very professional and easy to deal with fair quote and no surprises. He was thorough, methodical and you knew you were in safe, reliable hands. CH & HW system now working the best it has for many years. Highly recommend David & GRT.”
