Boiler area was left in a clean and tidy state. I have used Gasworks on very many occasions for various issues and have always found them to be prompt to attend and all their work has been of an exceptionally high standard. My house presented with many unforeseen and complicated plumbing issues when I purchased it and these have all been resolved by Gasworks. Their engineers are very pleasant and helpful." > — Which? Trusted Traders Consumer (5.0, via Which? Trusted Traders) > "The work on this occasion was a boiler service. It was done just as you would hope. The engineer arrived at the time we had booked, the work was done very considerately (our boiler is in the middle of our hallway so we were coming & going a lot around him, but this didn't cause any problems), and no mess at all. The booking of the appointment, and invoicing afterwards, was easy and efficient. Gasworks have been working for us for around four years and every piece of work has been to the same excellent standard - our boiler installation, boiler services, and a few other things. On a couple of occasions we've had leaks (not from any of their work, but from older plumbing) and they've come round quickly, and sorted the problem sensibly without trying to suggest lots of expensive / unnecessary work. All their engineers, and their office staff, have been unfailingly friendly and cheerful. I couldn't recommend Gasworks highly enough." > — Which? Trusted Traders Consumer (5.0, via Which? Trusted Traders) > "Gasworks offer a great service. They are always polite and courteous from point of office contact to their super team of engineers who come out and carry out the work. They are clean and tidy and extremely thorough. I would highly recommend" > — Which? Trusted Traders Consumer (5.0, via Which?

Trusted Traders - Public evidence last checked May 2026 ## Before you hire a plumber _What to check when choosing this kind of trade — general guidance, not a claim about this business:_ - Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top — in writing — before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints. - Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced — get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work. - Gas and boiler work is a separate, regulated trade — not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start. - Look for consistent reviews across several named sources, not one polished profile. - Check any verified credentials, and that the business details independently check out. ## Contact - Phone: 0800 999 8143 --- Source: MyTrustedTraders — https://mytrustedtraders.com/traders/gasworks-plumbing-and-heating-limited Real public evidence only: every figure traces to a named source and is cross-checked.
