"Brilliant, trustworthy company. Lorraine is always friendly, organised and so helpful when booking appointments. David, who carries out the work, is genuinely one of the nicest and most honest tradespeople I’ve met. He clearly puts customers before profit and his workmanship is top-class every single time. I’ve used GBS three times now — boiler service, toilet repair and a thermostat replacement — and each visit has been faultless. Trust is something I really struggle with when booking trades, but I’m so glad I found GBS. They’re reliable, skilled, honest and completely fair on price. This is a company you can book with total confidence, knowing the job will be done properly and you won’t be ripped off. Couldn’t recommend them enough!"

"I was very impressed with the service from GBS. Lorraine was incredibly helpful and friendly, quickly arranging—at short notice after someone else had let me down—for my old radiator to be removed and a new one installed so my redecoration plans wouldn’t be delayed. Danny carried out the work efficiently on the scheduled day and even returned a week later to address a minor concern I had at no extra cost. GBS communicate clearly, are punctual and reliable, and I would not hesitate to use their services again, thanks GBS!"

"Danny from Gas Boiler Services made an initial visit, free of charge, to look at our old boiler when it failed after 15 years of service. It was no surprise that he advised that its working days were well and truly over. He advised on a replacement and the quote was fine, so a couple of days later we were the happy owners of a modern new unit. The work was done to a high standard and very quickly finished. Danny was punctual and cheery and a good time was had by all. Lorraine's after service has been great and we have all the guarantees and Gas Safe paperwork in hand. I have no hesitation in Recommending this company."

"GBS arrived, did a boiler service and a couple of odd jobs (install gas cooker and replace a radiator thermostat). No messing about, just got on with the job and I got to learn a few things as well. Very happy and will definitely use again for my next boiler service."
