I inherited a complicated heating and hot water system which was not regulating itself properly, and I had had a couple of enormous bills. Daniel expertly diagnosed what was wrong, fixed it, supplied and fitted new controls and valves and my bills have been cut by more than half. He was quietly efficient, clearly highly skilled, courteous, polite and tidy. He helpfully explained what he had done and explained how to work the repaired system. The bill for everything he did was very reasonable. Any customer can have complete confidence in Daniel and I cannot recommend him too highly.
