Diamond Green Energy Ltd Avis 

Matthew went above and beyond to change a pump and service our aircon. Returning to our house the same day to fit the correct unit.

This company is fantastic. Been with them for 6 years. They fitted and regularly service our boiler. Nothing is ever too much trouble. Couple of days ago needed a new pressure relief valve. All sorted within 24 hours. Exceptional professionalism from Charlotte, Mark, Dan, and Drew. Charlotte answered phone immediately. Mark diagnosed the problem. Engineers Dan and Drew sorted it immediately. 100% honest, reliable,and trustworthy company. Highly recommended. Chris Jordan.

Great service throughout the entire process. Great comms, with a lovely and efficient customer service team. The units look great and are going to make such a difference next summer. Really nice installation teams over two days and great electrician, a pleasure to have in the house. Nothing seemed too much trouble, from the initial enquiries until the job was finished. Really pleased.

The appointment was easy to book and the service was carried out very efficiently. Due to gas pipe laying in our road, vehicle access to our house was not possible but Drew, the engineer, and his apprentice overcame this, saving us from having to re-book, and did a very good job. Thanks to them.

Excellent service from start to finish. We are very happy with the solar panel and battery system they supplied and installed.

The whole process was handled professionally, the installation team was efficient and tidy, and everything was explained clearly. What impressed me especially was the attention to detail after the installation - they even arranged for a separate company to come and collect all the rubbish and packaging, leaving everything clean and organised.

A very professional company, good communication throughout, and a high standard of workmanship. I would happily recommend them to anyone considering solar panels or battery storage.

All good, as usual

From the purchase of the boiler through to its installation six days later everything was stress free. Mark, the installer did a great job and explained everything I needed to know very clearly and concisely. This Company is fully recommended.

It was easy to book the Service for the gas boiler. I was messaged the night before to tell me when the engineer would be coming the next day. And on the day you get last-minute tracking right to the door. Service was done efficiently, and everything left clean and tidy.

Very efficient service for booking and carrying out boiler service.

Good communication throughout. The engineer who came was polite and very professional. Would highly recommend!

On time professionals and friendly

Diamond engineer contacted us to state was on their way and arrived within 30 minutes. Carried out a through service which identified a sticking 3 way valve which they rectified and showed me how to prevent the problem reoccurring.
Engineer was polite, professional and tidy during visit.
