GreenGenUK Reviews 

Great company to deal with. Recently had new air pump heating system installed. The installers were efficient and professional and did an exceptional job. The plumbers Craig and Tristan and the electrician Jordan were all conscientious about the quality of their work and even stayed on late some evenings to ensure the project was completed on time and the the highest standards. The level of communication at all stages was exemplary. We would highly recommend this company.

This is our second installation by GreenGenUK, George and Lewis did a great job removing our old gas boiler and then an excellent job installing our new heat pump and tank system. On time, great attention to detail with pipe runs and always spotlessly clean at end of day, we couldn’t have asked for a better experience. Zak and Treeve followed up with a super neat wiring job - we would honestly recommend GreenGen to anyone!

Ben and Andrew were excellent, professional clean and tidy and thoughtful with their installation. Recommended without reservation

Just had annual service for solar thermal and air source by Ben E. Excellent, above and beyond in attention to detail, checking everything is working as efficiently as could be and helpfully adjusting and explaining the timing controls. Professional and friendly. Thank you GreenGen, thank you Ben.

Adam and Finn arrived on time very tidy efficient hardly new they were here at all completed the work updated everything including our personal apps good luck in your new Exeter adventure.

We have just had our annual service carried out by Alastair at GreenGen who is very knowledgeable and made some fine adjustments that will hopefully save use some pennies.

We have just had a solar panel system involved, and from start to finish Greengen were excellent. Throughout the process they kept us updated with the schedule. The whole team on site were outstanding being friendly , courteous and very tidy. Electricians Zack, John and Cameron and roofers Simon and Jack all provided a very professional service

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.
Max, John and James came to fit our second Tesla Powerwall. 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.

The whole process from start to finish was really easy
Our system was installed by Jack / John & James
Very professionally people to deal with
The installation was in February wish we did it a while ago it’s preforming great our electricity bill is already cut in half even this early in the year

Helpful, friendly staff who talked me through my air source heat pump installation. Jack M was really thorough and came back to check everything was working as it should

New Zappi charger installed. Max fitted and ensured the new system was working ands set up on the app. All done on time with minimal fuss and clean and tidy.
I would recommend GreenGen again.

Great service from enquiry to quote to installation. All the staff who came were friendly and professional. Ryan was here the most, doing pipe work etc. He made a good neat job of it all and was professional, pleasant and polite, taking plenty of time to explain what he was doing and how I could access the filters etc. Very happy customer!

Very happy with Ben who did a very thorough job servicing my heatpump today. Very knowledgeable and helpful!
Thank you very much!

Called Greengen as a local supplier to me purely for some advice. I spoke to Neil and explained my situation; he was happy to spend the time with me to give me open and honest unbiased advice. He did not try to drive any sale and was very knowledgeable, he re-assured me and provided the answers and conclusions from a professional perspective in the first instance (unlike other local companies). Would certainly be a company I'd happily look to deal with should my situation change based on that one phone call.

Heat Pump and EV charger installed 4 weeks ago. Installation went smoothly, most of the work being done by Craig and Andrew. Had a problem a couple of days later (solder joint failed), but it was resolved within a couple of hours - excellent service on a Sunday morning. To be fair, the joint that failed was in a tricky position, and didn't leak for 2 days.
All working as expected now.

Could not have been better! John and James worked tirelessly throughout their time here. Answered all my questions and performed the nearest install. Brilliant.

We started our Journey with getting an ASHP and then Solar PV with battery. The staff were very helpful with numerous changes to the system to help us get the best system for us

Just had an air source heat pump fitted by GreenGen- we were very happy with their work and their attention to detail. Must particularly mention Craig who spent a week installing the system and went above and beyond in terms of making sure glitches were ironed out. He was also so friendly and respectful - can be hard having people working in your house but he was great - even indulged the 55 kg dog who wanted to be present at every stage of the installation

Wow! How good is this team, (Zakk, Creeve, Milly and Liam) at GreenGen UK? From our first enquiry to the finished product 10 out of 10. Efficient, friendly, professional and all with great attention to detail.
GreenGen also fitted our air source system with all of the above attributes. Thank you GreenGen.

Competitive price, hassle free installation. Turned up as agreed. Morgan was quietly competent at laying out the many components and everything looks neat which was a, challenge in a confined space.
