Excellent company, highly recommended
I can't recommend this company highly enough. My father used them for his boiler installation and subsequently, servicing of his boiler and gas fire. He was always very complimentary of the service received from the engineers and the office staff, and the price for the work was competitive.
Since my father passed away I have dealt with Louise and Charlotte in getting access to documentation that I need to be able to sell his property. I have made numerous request for information, and it has all been provided very quickly. This is particularly appreciated as they are taking time to assist someone who is not even a current customer, and it has made my life easier at a difficult time.
I would definitely recommend Diamond Green Energy to any potential customers.

Thank you for choosing Diamond Green Energy and your continued support.
bad workmanship
it took way bto long to carry out my repair
when the engineer replaced my thermost rather than screwing it over the existing holes he decided to place it 2 cm lower thus leaving 2 holes in my wall also it was not level i moved it back up to cover the holes
i do wonder if he has not got the intelegence to do this should he be working on my boiler

Dear Mr Coombe,
Thank you for your review.
I do feel a 1-star review is disappointing, particularly given we have worked with you for a number of years and installed multiple boilers for you without previous issue.
I’m sorry to read your comments and for the experience you feel you’ve had. As a customer since 2021, this is not the standard we aim to deliver.
In relation to the thermostat, our understanding is that the engineer used the existing fixing points where possible. Due to the design of the new control, the holes did not fully align, and he avoided creating new fixings as the wall appeared thin and there was concern the screws would not hold securely.
At the time, the installation and controls were demonstrated, and no concerns were raised. Had we been made aware, we would have been happy to discuss alternative options.
Regarding attendance time, your repair was scheduled based on the fact that your heating and hot water were still operational, allowing us to prioritise emergency breakdowns first.
We always aim to resolve concerns directly and fairly. I would welcome the opportunity to speak with you and see if there is anything we can still do to move things forward.

Rescue Rangers
I had disaster with my previous solar Company to the extent that they removed my solar system. Diamond Green came to my rescue. They installed a new panel and battery system. The new panels installed by Declan were neat tidy and well set out followed by Arthur who did a great job of installing and explaining the electrical system. Great company would recommend to any one. A company that uses real trades people.
