I ordered a new boiler from Diamond as my old one had given up. We also wanted to change to a combi boiler and move it to where the old tank was. As we had no hot water or heating Diamond re-arranged engineers to fit us in. The whole process from my initial contact to the job being completed took less than a week. Nothing was too much for Steve the engineer or those in the office. Steve kept us informed how the work was going. Made good the removal of the old system and always kept things tidy. We are very happy with the new system, installed just in time for the cold weather thanks to Diamond

From start to finish this company provided an excellent service. Steve helpfully guided us through the complexities of selecting the correct boiler for our needs and patiently answered my many questions. The quotes were clear and easy to understand. The fitting was done on time and the house was left clean and tidy.

I'm so impressed after several years of relying on a British Gas contract - brilliant and fast service right the way through. The engineer was bang on time and I even received a text when he was on his way with a tracker so I could where he was. Very professional and extremely thorough - checked and explained everything. Couldn't ask for more. Highly recommended.
