Don't just take our word for it

David
They dealt with an issue at my mums house, came Bill came round 15 mins after first message was sent, understood the issue and arranged a time to come back. Both lads were professional, hard working, tidy and responsive. Would definitely recommend these lads to anyone looking for work to be done. Couldn't have wished for better tradesman.
Philippa
As usual bill did an excellent job. We have used him several times from full boiler installation to servicing. Quick, courteous and always on hand to answer questions, I can not recommend him and his team highly enough.
Lydia
Billy’s team installed new radiators throughout our house for us with the upmost care and expertise. Incredibly the floorboards afterwards looked almost untouched and the fittings were spot on. Brilliant work, would wholeheartedly recommend.
Dave
Had old boiler, old storage tanks (hot&cold) etc removed and replace with modern combi boiler system. Quick, clean & efficient - 3 guys worked 13hrs and completed job in one day. Excellent service and great heating system.
Alison
