Billy did a fantastic job. He fitted gas central heating in our flat, including a new boiler, pipes (both internal and external), radiators, and the removal of the old service heaters, all in two days. I had had several other quotes and his was significantly cheaper. I honestly can't see how these more expensive companies could have done a better job as we are really pleased with the quality of Billy's work. He was prompt with email and phone contact, and was at the flat when he said he would be. All in all, I would definitely recommend Billy because, for price and quality, I think he does a fantastic and quick job.
