GESS Renewables Avis 

When i have called up, wether it is for advice or problems they offer a great service, it is reassuring to know they are monitoring my system 24/7 to check for problems and identifying them before i need to call.

Had a great experience with Gess, installation for my solar and Tesla battery went smoothly, and scaffolding taken down as fast as it went up. Also recommended my family to have solar and they have since had their installation too.

The Tesla Powerwall 2 was very professionally installed by GESS and has been running since May faultlessly. The gateway is completely silent and the switch overs to and from the battery are unnoticeable. The whole system works perfectly and is easy to see on my iPhone exactly what is happening. Would highly recommend.

Gess Renewables installed solar panels for me, and a battery a year later. They were friendly and easy to deal with and have been very helpful in following up any issues. I was glad to have found them, because they gave me far better advice than some other installers I contacted, and they are a genuine and trustworthy company.

We have had a Solar PV system plus a Tesla Powerwall installed by Gess. I can’t fault the service that we have received throughout the purchase experience. From initial informal conversations at the warehouse, the site appraisal followed by the installation of both aspects of the project, we were treated in a friendly and professional manner throughout. The engineers, on both visits, took away all of the rubbish and swept up after they had completed their respective installations. Very happy with the service and would be pleased to recommend them to friends and family.

About 6 months after placing an order for solar panels + battery with barely any ongoing updates on timing.....we recently finally had the panels installed by a couple of nice technicians. Still no news on when the battery will arrive though. Not even an ETA. Unfortunately a technical fault was also reported the day the panels got installed (I guess the may not have checked it before leaving?) and after reporting it to the firm multiple times they finally confirmed it would require another visit scheduled for approx. 1 month after the original installation. I guess that can happen and they are very busy, but the problem is that they in the meantime are refusing to remove the scaffolding, which is currently blocking access to our bike storage. Most recently they have stopped replying to our requests for updates. Just ignoring us even though we have explained that we were never informed that they would block access to our main means of transportation (live in central London). Most solar installation companies are probably not easy to deal with as this is a bit of a "cowboy market"and GESS might not be an exception. Should probably have gone with Octopus or another established supplier with a strong focus on customer service.
