GreenGenUK Reviews 

Highly recommended. Just had panels, inverter & battery with double EPS plug fitted. Scaffolding included, all within 4 days. Simon(+1) did an excellent job fitting the panels on the roof on day 1 with Jake(+2) doing all the electrical day 2&3. Scaffolding down day 4. All the team were very professional, knowledgeable, polite and very friendly throughout. Not the cheapest on the market however the quality of work was worth it. All the tech stuff (apps etc) installed and explained before leaving, help line available for when we forget it all. Good supply of Tea, Coffee and choc biscuits did help. Excellent job, well done GreenGen.

We are very happy with the way the work was carried out on our heat pump installation . The plumbing team of Jack G , Dale and Archie , were hard working , left everything clean neat and tidy at the end of each day . They were all very polite and respected our property and answered our questions as worked progressed .
The electrician team lead by Cameron were equally hard working , tidy and polite . Cameron was very patient and helpful at explaining the operation of the system .

The two young men were very helpful. Explained what had to be done.
I can’t guarantee that we understood everything but they seemed to know what they were doing.

Jordan and John were really helpful and patient to explain the system on the app, laptop and the external boxes. I’m also reassure that I can call on them if I have any queries.

Cameron and Trieve are really great guys and helped sort out the issues with the Eddi and Zappi. They were thorough in their work ensuring all the systems worked. Checked out the energi app and explained its operation.

Excellent communication from the start and really good service from knowledgeable people at every step. Our installation of heat pump and radiators was complicated but carried out with no fuss and I was kept informed at all times of what was happening. There was no mess and the house was left spotless. I would like to personally thank Ben whose installation of insulated copper piping could be displayed in the Tate, it is a work of art! Thanks to Ben and the reasonably good weather the two weeks never felt like disruption, I often work from home and the entire team were a pleasure to have around. Plus I now have lovely new radiators in rooms that previously had no heating at all and it works beautifully. I wouldn’t hesitate to recommend GreenGenUK

We had solar panels and battery system installed by James and Treeve. They were very pleasant, carried out a professional job and explained the system before they left. They are a credit to the company and restored some lost confidence in GreenGen.

The initial survey was troublesome but the company
worked professionally to overcome the many difficulties
This was a complete package air source battery and solar on an older property incorporating a gravity fed one pipe system It was a pleasure to experience the professionalism of all of the GreenGen workforce particular recognition to the skills and input of Sean and Adam

Alastair provided great friendly service and advice.

Arrived when said they would. Friendly, tidy and helpful. Nothing too much trouble. Quick and efficient.

Recently had a solar and battery system installed by GreenGen.
I found the process very easy and the design was tailored to my needs.
The installation team encountered some challenging weather conditions, but Simon, John, Fin and Jake completed a professional job and are a credit to the company.

Excellent roof installation of solar panels
Simon runs a very efficient team and made the process efficient and professional

Definitely recommend Simon @
Green Gen

Excellent service from Jordon

Alastair arrived exactly on time and fixed our hot water problem within an hour. He was was affable and thoroughly knowledgeable and left everything tidy. Would recommend green gen to anyone

Very pleased withall of the GreenGen installations, and the latest fitting of the PV panels was done efficiently and without fuss. The installers Ian & Zakk are to be commended.

Installation went without any problems. Alistair worked diligently throughout, tidying up every day before he left. No hesitation in recommending GrenGen.

Excellent service from start to finish. At the point of installation Matt - plumber - was helpfulness personified. Nothing too much trouble. Very pleased and thoroughly recommend.

Cameron visited our home to rectify an issue with our heat pump and provided a friendly, helpful and courteous service. No hesitation in recommending GreenGenUK for any green energy solutions! Top work!

GreenGen completed the work of installing solar panels at my property on Wednesday 6th. March, 2024. From the beginning of my involvement with GreenGen, they were pleasant, efficient and easy to deal with - the ones who came to my home in connection with the installation, and the ones I dealt with at their Office in Helston. They worked hard, and readily explained whenever I had a querie about something. I was very pleased with the service!

However, when I had to contact the Office on Saturday, 10.October, upon discovering that I had no water, I was extra impressed with their service! I sent an email and phoned their Office, some time in the afternoon on Saturday, so they hopefully could book me in at the beginning of their next working day. I had expected to speak to a robot, but a real, live person answered my phone. So refreshing in this highly digitalised and robot orientated world! A bit later I discovered I had also got a text message from someone at GreenGen, asking me to call him. I did. The one I spoke to thought, like me, that the lack of water must have had something to do with the fact that the water tank in my garage had been turned off as they worked - and that they had forgotten to connect or reconnect something before they left. He said he would come to my place then, to check, but it would take him an hour and twenty minutes to drive here, as he lived fairly far away in Cornwall. I told him I had bought drinking water and got some water in a container from my next door neighbour, so he did not have to come immediately. However, he replied that I SHOULD have water in the tank, and stressed that if I was at home, he would come “ now”. He was there at about 8pm, leaving just before 10pm - but not before checking that I had water everywhere I should. An oversight can always happen - it is what the company then DOES with that, which matters! I learnt that it was the owner of the company himself who had come to help me so I should have water at the weekend!

This was PROPER, OLD FASHIONED SERVICE, PROVIDED BY A NEW AND MODERN BUSINESS! I was both impressed and extremely grateful! So glad that I had gone with GreenGen to have my solar service installed and got them up and running.

Thank you to ALL at GreenGen from a very satisfied customer! I look forward to learning more about how everything with my new system works & how I can maximise the benefits, both for the environment, and financially.

With many thanks,

I would not recommend this company at all. Tried to go local to support a local business. Don't waste your time! contacted them in Jan23 and agreed a site visit Jan 23 on visit agreed a system, Solar battery hybrid all tucked in loft with 11 panels on the roof. Using a Solis system, upgraded at the last minute to GiveEnergy battery and inverter waited for instillation 10 month for instillation Oct23. firstly scaffolders used, damaged masonry on house and built scaffolding on top of rose bushes, crushed them actually. Final site inspection showed area in loft for inverter + battery, happy with siting. GreenGen Emailed the following day saying not possible to put it in the loft will have to go in the garden, when I queried why this has happened now they said the man surveying didn't really know how big it was. So why did he conduct the survey? I was ready to cancel the system when by magic they could fit it in the loft. System fitted, and installers left. Checked roof and found they forgot to fit a solar panel. This was rectified the following day so that was rectified correctly. Wire trunking to consumer unit looked like a 3 year old had fitted it. No caps on end filled with mastic that dribled out down the wall. Finally start to use the system jan24 as we are on Octopus Tariff to find that the battery immediately discharged when on timed home demand. The reason we invested in this system was to charge the battery on a cheap tariff over night and discharge it early evening. Spoke with customer service at both GreenGen and Give energy. took 4 days for GiveEnergy to decide that the timed home demand is not compatible with the inverter fitted, so can't be used this way. when I called to speak with Adam I was told "he is extremely busy what do you want". I pointed out he had said he was available all day so I called rather than emailed. GreenGens response was sorry it doesn't achieve what you thought it would. I would also point out that without any security questions or passwords they logged into my system and began adjusting setting (sound familiar) Two dreadful companies working together.
15k system that does not achieve what we were sold. For goodness sake look else where. I would give a negative star but you have to give one.
