Very helpful
very helpful engineer who serviced our boiler but also fitted our new Tado thermostat controller. As Tado is quite new, there was a bit of learning from both of us of getting it set up but we got there - appreciate their patience!Job location: PO1510 Central Heating

We would recommend Diamond Green Energy
We had 2 air conditioning units installed, not central heating, but air conditioning wasn't on the list I had to choose from. Good experience using Diamond Green Energy. Tradesmen were nice, arrived on time. Cleared up after themselves and explained how to use the unitsJob location: PO1310 Air Conditioning Installation

Full check of a new gas system
Steve was a great help ensuring we got the service we were looking for. Robert Nugent provided an excellent service, explaining what he was doing at every step, performing a thorough check of the boiler, cooker and central heating system which included bleeding all the radiators…no more clunking. Well done and thank you.Verified reviewerJob location: GU2710 Central Heating

New boiler installation
We needed our very old boiler replaced with a new boiler and Hive system. They did an excellent job, especially as the original boiler was in an awkward position and they went out of their way to fit the new boiler close to the original. They were very knowledgeable, reliable, polite and hard-working. Very pleased with the work done. Great customer service - from going through the boiler survey and boiler options to the installation. Happy to recommend them.Verified reviewerJob location: GU5110 Ground Source Heat Pump Installation - GSHP
