A family business

When husband and wife Ian and Louise Simm launched Diamond Gas & Heating in 2011, they knew they could offer something better than the local competition.

The pair had military backgrounds, each serving in the Royal Navy, with a combined service of 28 years. Ian had been an engineer and Louise in communications.

With their combined skills and background, the team knew they could offer the competitive prices of a local gas fitter, without compromising on quality and customer service –  all while offering 24/7 call-outs and complete peace of mind for the customer – something that truly sets them apart from the rest.

Ian was on time. His knowledge and logic with figuring out the antiquated system we have is impressive. We're waiting for his quote to bring our system into the 21st century. My son recommended Diamond after the outstanding service he received from this company.

We have a service contract with Diamond and also Mum has her boiler serviced too. Always very happy with the service and customer support. Drew arrived on time, kept in contact with arrival time which was great. He was very thorough and has arranged for replacement parts which are covered under the contract. Thanks Drew and Diamond Heating.

Drew arrived well on time and very efficiently serviced our Viessmann boiler. He was very helpful and very patiently answered our questions and explained anything we weren't sure of, left everything clean and tidy when he had finished and was extremely professional throughout his time here. He is an asset to your company.

Had an issue with our boiler not working, and hadn’t seemed to work right since moving in a year ago. Had previously had engineers round but none of them seemed to understand our heating system. So as a last ditch attempt to fix it, I called Diamond Heating. They squeezed me in for a next day call out, and as arranged, Steve the engineer turned up. He knew straight away what the problem was. Fixed it, and explained clearly how the heating should work, that even my wife said she now understands the workings of a heating system! So impressed that I’ve now taken out a service plan with them! Well done Steve and all the team at Diamond Heating.
