I honestly couldn't fault diamond boilers. Rob is a star. I received a quote for a new boiler and filter and the work was carried out the following week. Great team and they were so helpful.

Our veterans centre needed a bespoke air source heat pump system designing from scratch. Thanks to Robs design skills the system was created and fitted whilst we were able to continue to conduct our daily duties. The team are extremely clean and professional and were most considerate toward our staff. We would strongly recommend them to others.

Had a Trianco air source heat pump installed and couldn’t be happier with the whole experience. The team were professional from start to finish, explained everything clearly, and the install was completed to a really high standard. They handled all the paperwork for the Boiler Upgrade Scheme, secured the £7,500 grant, and I barely had to pay anything which made a huge difference. The system is running perfectly and the 10-year warranty gives great peace of mind. Would highly recommend to anyone considering a heat pump.

This team absolute fanstic very profesonal all work completed to a very high standard very polite cant thank them enough thanks Rob& Luke.

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.

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.
