Home heating boiler repair by experienced technician

Ryan

"I had to contact David recently about an elderly parent's boiler not working. David promptly called in the evening after a busy day, quickly diagnosed the problem, and with parts fitted, fixed the issue at a reasonable cost, but had advised that a new boiler would really be what's needed. Just a few months later, the boiler started playing up again. A new boiler was ordered and fitted, hassle-free, with corrections applied that should have been there from the original installation. I just cannot praise David enough, professional, kind, and patient of a saint! (and on speed dial lol!) You will not be disappointed with 1st Class Gas. Thanks, David!"

Jo

"I couldn’t recommend David more. He answers calls, comes on time, and is meticulous in making sure everything is the way it should be. He serviced my Mum’s boiler meticulously, (yes, I will use that word again!!), fixed a pipe that two previous plumbers botched, noticed cracks in the pipes that went from the gas bottle to the cooker, and just gave us such a strong sense of confidence in his work that we now have him in our phones to call again if we have any concerns. You can trust this company."

Kelly

"Wouldn’t go with anyone else, can’t recommend David enough. Serviced my boiler earlier in the year and had him out recently due to a mistake of my own. Both times there for when he says he’ll be, very friendly and thorough with his work, happy to explain what he’s doing."

Danielle

"First class service from David @1st class gas! He was the first tradesperson who didn’t let me down. He gave me options, charged what he quoted, and was on time and very tidy. Lovely, friendly guy, and I will book again for my yearly boiler service. Thanks again, David."

Trevor

"I contacted David about a problem I had with my boiler, and he gave me my options to repair or replace. Decided to replace it, and he had me back up a running in no time at all. No hassle at all, didn't even have to take time off work, just left him to it.
Really nice and a tidy job. 1st Class. Clue is in the title."

William

"Called out fast. Fixed it fast. And followed up to check it was all definitely fixed. Nice man, and good service. David fixed my old boiler and saved me from having to pay at least 1600 quid for a new one. Call him if u need your boiler sorted."

Helen

"Called 1st Class Gas to repair my boiler, this was done promptly and at a reasonable price. Got my boiler up and running, and also carried out a service of my boiler and fire. Very helpful and couldn't do more for me. Definitely recommend 1st Class Gas (David)."
