Billy and his team have just put in an entire heating system from scratch for us - new boiler, unvented cylinder, brand new pipework and all radiators. Billy was super efficient, friendly and totally trustworthy - we gave him a key and went on holiday so he could get on with the work which was completed much more quickly than we imagined. Our neighbours (unprompted) told us they arrived at 7am each day, were considerate about noise and were just generally very amenable. Really happy with the work and would absolutely recommend.
