Obtained four quotes for replacement of old boiler system with hot water tank to a combi boiler. Ben was by for the most customer focused, and did a brilliant job and completed the work in two days. He even replaced a leaking gas pipe and repointed two ridge tiles which were not part of the quote. He cleaned up after completion and left us a good as new. Work done in August 2017 and after four months everything is perfect. I could not recommend him highly enough. Superb professional.
