Kept informed of engineer arrival
Kept informed of engineer arrival. Turned up on time as stated. Stephen was very pleasant and polite. Did a good and thorough service on my boiler, taking photos of all he did. ( Thought that was a good idea). Very satisfied that I chose Diamond Green Energy Ltd for my service requirements.

Thank you Mr Etherington for taking the time to review us. Yes, one of the reasons we take photo's, is so, if you call in with an issue, we know exactly what products you have.

The engineer was polite and worked quickly. The problem we have is with UW as the engineer has recommended we have a new smart meter after each visit but they are not following his advice

We are absolutely delighted with the work Diamond Gas have done putting in the new Air Source Heat Pump . Its been a long journey navigating types , heat loss reports , planning permission, Epc certification, and the team have been brilliant supporting us through it all . I have really appreciated the excellent communication throughout.
On doing the works Nick , Drew and team were thorough, clean , polite and friendly throughout. Nick was great at explaining how the new system worked . We had a small leak from one of our old radiators post installation and the team responded going above and beyond to help us out ( as it was losing pressure in the system) .
I would thoroughly recommend this friendly expert team to anyone considering a new heating system.
Thankyou 🎉!

A Diamond bunch ☺️
Fantastic company, polite, friendly and most importantly for me trustworthy. They service my boiler and found them all very good as a result I asked them to install (at very short notice) a boiler at my parents house. Thoroughly recommend them.
