Highlights

"A fantastic company to work with—polite, punctual and professional throughout. I was given a one-hour arrival window the day before, which made it really easy to plan my day. David, the engineer, was friendly and efficient, and left me all the paperwork I needed. The boiler service report was emailed to me within the hour, and payment was quick and straightforward. The service was carried out to a very high standard. Highly recommend."

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!
