See what our customers are saying

Overall, I’ve had a very positive experience with GreenGenUK as a company. I found the installation process smooth and the engineers very polite and helpful. GreenGenUK also came in first place for cost!

 

I just wanted to personally thank Jordan and Dan for going above and beyond to ensure everything was installed correctly and working as it should.

See what our customers are saying

We had a helpful and informative initial discussion and planned proposal that suited our needs and this was followed up promptly with the pre-installation survey. The installation team were great, they were polite and very professional, answering any questions we had, were respectful of the property and did an excellent job, and also the scaffolding team.

 

The system has all been working well since, love the app to keep an eye on the figures, we’ve had good follow up through emails and the communication has generally been extremely good throughout. We would definitely recommend GreenGen to others.

This is the third time we’ve had work done by GreenGen. All staff involved from quote to installation have been excellent. What a fantastic company with such friendly, respectful and professional staff…

 

They did a very good job and Max made sure from the start that I understood what they were going to do and checked that I was happy with the location and fittings before they started work.

See what our customers are saying

From initial contact to the completed installation all deadlines were met as agreed and I had excellent communication from the main office at all times. The roof panel team had some really bad weather to put up with but they got the job when they said they would and left the site clean and tidy…

 

Some electricians go the extra mile but Cameron ran an extra marathon in trying to unravel the mysteries and decrepit fabric of an old electrical system with the new inverter even to the point of working on his day off to ensure everything was running smoothly, this really is customer care at it’s best and Cameron is a credit to the GreenGen team.
