Dave and his team were fantastic from first message with Rachel finding a slot same week.

Bradley attended and done a fantastic job fitting our downstairs toilet which has been out of use for months. As a result this has kept the wife happy which makes my life happy !

I won’t recommend anyone other than Gas Flow Heating and will use them again.

With an age old issue with our underfloor heating, it needed a power flush. The team that arrived, were friendly, knowledgeable and trustworthy. They not only proceeded carefully, preparing my house to ensure the flooring was protected, they methodically carried out the work required. Resulting in my underfloor heating working perfectly, the first time since it was installed 3 years ago. I can’t believe we found these guys and that they are so close. Anybody that requires trustworthy plumbing experts, I thoroughly recommend.

What more can I say except that the service I’ve received from Gas Flow has been excellent, they are now our go-to and trusted gas and plumbing company. In the last 6 months they have installed a new boiler for us, a new gas run, a new shower pump, and fixed our downstairs toilet. They also helped to re-pressurise our pool boiler and went out of their way to do this. Dave and his team were all extremely professional, polite, helpful and approachable. They treated our home very respectfully too, taking off their shoes before walking on any rugs or carpets, laying down protective film/blankets to protect floors, and cleaning up after themselves daily. I also found their prices to be very reasonable, particularly as you get the strength of a very big team behind the job – and they all pitch in together when needed to meet deadlines.

I would thoroughly recommend them.

This company are amazing! They came out to fix a fault on the day we reported it, we were unexpectedly delayed so were not home but the engineer waited! Good contact by phone and text to keep us updated. Job finished to a high standard, photos of all the work sent at the end. Reasonable price and wouldn’t hesitate to use again. Brilliant service, highly recommend.
