Diamond Energy Reviews 

The two guys from Diamond Boilers fitted our new boiler (Veissman) today. They arrived on site at the appointed time. CV19 procedures were followed (masks & sanitizer used). I cannot fault the professionalism of the two guys: there were polite & courteous at all times and their attention to detail & following fitting instructions to the letter. We would definitely recommend this company to our family & friends. Thank you to Diamond Boilers - you were excellent!!

Boiler Service

I have just recently had my boiler serviced by Diamond Boilers and i could not recommend them enough! The engineer arrived punctually and conducted himself very professionally and competently throughout.

Will be using them next year without a doubt.

Excellent service from start to finish. I received a very reasonable quote promptly which was great as my old boiler had totally packed in! They arrived at the time they stated they would. The work they did was very professional and they did a really good job of cleaning up after themselves. They were very polite and courteous and I would certainly recommend this company to my family and friends!

My boiler installation was very neat and tidy, they were very efficient explaining all we needed to know about our new boiler and workings, very pleased as we now also have a shower with lots if pressure too, excellent value, highly recommend these guys, very polite too.
