Jamie did an excellent job replacing the whole central heating system. We had a very old back boiler with one pipe system. Jamie took that all out and put a modern two pipes system with a BAXI 630. Initially I wasn't sure about BAXI but we were on a tight budget and it has a 7 year warranty so we went for it. Very happy with it, it is very quiet. Jamie also did it pretty quickly, 4 days for the system and an extra day for other extra bits we asked for. He also fixed a couple of old leaking pipes and fit the new taps and a vanity unit in the bathroom.
