What Clients Say

When our boiler broke down shortly after our daughter was born panic set in. A1 Boilers came and fixed the problem quickly and cheaply and provided us with friendly helpful feedback on our systems’ performance.
Mr D. Fraser Moore, South Tottenham, London
We found A1 Boilers to be very professional when they installed our new boiler. The Engineers worked quickly, efficiently and provided an excellent service throughout, answering any questions we had. This gave us complete confidence in the company and we would highly recommend A1 Boilers to anyone.

Lifesaver! We had tried four companies in tryng to fix our boiler. A1 were the only company to bring our hot water back. Very quick and straight forward. Thoroughly recommended!
Miss Gemma Barron, London, NW6
 
Three previous engineers failed miserably to fix our boiler, when along came Simon from A1 Boilers. A ‘result’ indeed with instant success. Have used A1 on a second occasion with 100% satisfaction. Don’t think twice, A1 are alright.
Mr I MacKenzie, London, E11
It is unusual to find an engineer who one would be happy to recommend to a friend. Simon from A1 Boilers breaks the mould and I would have no hesitation in passing his name to anyone in need of an efficient, reliable and reasonably priced service.
Matthew Crawford, Upper Street, London N1
Courteous and fast service, they fixed my boiler quickly when it was broken. I have been calling them since for servicing as they know what they are doing!
