Highlights
"I can’t fault anybody from this company and I dealt with four different people. They were hard working, polite and committed to completing the work professionally . Any questions I had they answered quickly and I had a few. Wouldn’t hesitate at all to recommend this company . Great group of people"
"Rob did some work for us recently and we were really impressed with how friendly and professional he was. The work carried out was to a great standard and reasonably priced. I've already recommended him to friends and would definitely use his services again if needed."
"We had our air source heat pump installed by Diamond Boilers and couldn’t be happier. The team were friendly, reliable, and did a really neat job. Everything was explained clearly and the whole process felt easy from start to finish. It’s working brilliantly — we’d definitely recommend them."

Before you hire a gas engineer
By law, anyone working on your gas appliances must be on the Gas Safe Register — ask to see their Gas Safe ID card and check the licence number at gassaferegister.co.uk before they start.
Never let an unregistered person touch your gas: unsafe gas work risks carbon monoxide poisoning, fire and explosion, and is a criminal offence.
For a boiler or appliance install, get the work and price in writing and keep the Gas Safe / Building Regulations certificate they are required to give you.
Confirm they cover your area and can actually come out in your timeframe before anything else.
Read recent reviews for reliability and turning up on time — not only the quality of the work.
