Diamond Green Energy Ltd Avis 

I have been using Diamond Green Energy for several decades and I have always found the service excellent. The engineers are polite, friendly and do a perfect job whether big or small and leave no mess. The company has moved with the times and the prices are competitive. I would recommend.

Diamond Green Energy installed our solar panels and battery system, and the whole experience was excellent. They were professional, efficient, and offered a very competitive quote.

Arthur and Declan were absolutely great during the installation – friendly, hardworking, and very professional throughout. Jody in the office was also incredibly quick and helpful in answering any questions we had.

I can highly recommend Diamond Green Energy.

Robert the engineer was very efficient when servicing our boiler and informed us on what he was doing

Engineer a nice guy, arrived on time.and completed service without issues

The installation team, Luke & Matt, were very professional and did a brilliant job

Diamond energy engineers have been kept proving they do the job neat and clean with great customer service. Thank you Robert Nugent from Diamond energy for the great job done today.

I've been getting annual boiler services from Diamond for several years now. Always a good job. Highly recommended.

The engineer arrived early in the expected time frame. Then promptly set about the task in hand. The service was conducted efficiently and courteously.

The company are always ready to help, the arrangements for a home visit for my yearly boiler check were clear and every thing happened as detailed. My boiler was checked and I have received my new certificate.

Good concise information about my boiler without being pushy for repair .

Engineer arrived as stated. The engineer tested, cleaned, appliance, inspected hot water tank and tested peripherals, reset clock as had gained time.

The chap who fitted the boiler was so polite friendly
and efficient. Nothing was too much trouble for him.
Steve Bell. And I can't recommend Diamond Green
Energy enough. Thank you to everyone. It was a pleasure to know you all.

Always get excellent service from Diamond Gas, the engineer Steve was friendly and efficient

An experienced engineer with a pleasant, friendly manner who completed the service very efficiently.

He was friendly, as always, and very efficient

Excellent service but Robert went the extra mile to do safety checks for Mum's bungalow. We are now aware of a couple of issues that need to be addressed.

When I was unsure of what to do, Louise went the extra mile and called me to explain and put my mind at rest.

We have used Diamond for years and I cannot recommend them enough, thanks everyone.

Engineer arrived between the time given and was very polite. I showed him where the boiler was and he wanted to check the meters so he did that to. Service completed very professionally.

I have never been keen on having services personnel into my home to carry out maintenance, servicing or repairs - until we found Diamond Energy!! Every aspect of their service delivery is A1 from ease of booking through to job completion and payment.
The engineers we have met have all been genuine, courteous and extremely knowledgeable in their trade. Thank you for delivering another stress free service.

Helpful as always. A good company to deal with.
