Highlights
"Very happy with the quote and installation from Diamond Green Energy, went way faster than I assumed, very happy!"
"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."
"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."

Smart checks
Before you hire an electrician
In England and Wales, notifiable electrical work (new circuits, a consumer unit, anything in a bathroom or kitchen) must by law be signed off under Part P of the Building Regulations — confirm they will handle that.
Prefer an electrician registered with a government-approved competent-person scheme (NICEIC, NAPIT or ELECSA) so they can self-certify the work meets the wiring regulations.
Insist on the Electrical Installation Certificate (or Minor Works Certificate) when the job is done — it is your proof the work is safe and compliant, and you will need it if you ever sell.
Look for consistent reviews across several named platforms, not one polished profile.
Check any verified credentials, and that the business details independently check out.
