  Very pleased with my solar, Powerwall 3, Tesla inverter, and whole-home backup installation from ESS Group. After researching many installers, ESS stood out because they offered the Tesla equipment I wanted, took a thoughtful approach to the design process, and have an established local presence that gave me confidence they would be around to support the system long term. Every member of the team I dealt with was knowledgeable and professional. Nick was excellent during the site visit, taking the time to understand my requirements and discuss different options, while Bill and the installation team delivered everything exactly as promised. The installation was punctual, tidy, professional, and well explained throughout. What impressed me most was how carefully they listened to what I wanted and then designed a system around those requirements rather than trying to fit me into a standard package. The system has performed perfectly since installation, and the whole experience was smooth from start to finish. I would have no hesitation recommending ESS Group to friends and family.

  We are extremely satisfied with our solar installation and it was a pleasure to agree to a local installer to complete the job after spending some time in research and obtaining quotes from several other companies. Although never having installed a Sigenergy inverter and battery system before, Nick at ESS was more than happy to add Sigen to their knowledge base and obtain and fit the kit that we requested. The install and commissioning was straightforward with Nick giving it a good 9 out of 10 which cannot be bad for a first install. Thus very happy with our choice of inverter and can also thoroughly recommend ESS as an installer for houses or larger premises. Nothing to do with ESS but do allow time for the whole process to be completed as it took 4 weeks for G99 agreement from the DNO before install and then another 4 weeks after the install for the DNO to agree to power export. All in all - A Great Job done.

  We have used ESS for a number of projects and all have been done in a very professional manner. They have just replaced two broken inverters in our house. ( one old one was broken and the other past its ’sell by date’!) From scaffold erection, solar panel cleaning, bird defence to new installation and removal of old inverters and scaffold removal everything went very smoothly

  The Inverter for our solar panels recently failed and we received excellent advice from Nick about a replacement. The work has now been completed and we were very happy with the quality and efficiency of the service from ESS.

  I had an issue with my electric meter that wasn’t fitted properly by a previous electrician, which caused ongoing problems and a lot of frustration. Thankfully, After speaking to Nick they came out and quickly rectified the problem. They were professional, and Clean The fix was done efficiently and properly this time, giving me peace of mind. I really appreciated their Communication Highly recommended if you want the job done right!

  Highly recommended. We used ESS to install solar panels and a Tesla Powerwall. They were able to complete the installation when Octopus Energy would not, with Nick and his team finding solutions to overcome some design challenges. They also went above and beyond to ensure the installation was neat and fitted within existing electrical cabinets, whereas other installers wanted to place equipment in our porch, which would have been unsightly. They have also been very quick to respond to any follow-up questions. In short, ESS provided a friendly, efficient service, and we could not be happier with the result.

  Happy to recommend Nick and his team of electricians. They installed a powerwall for me in 2019 and we’ve added another last year.

  ESS installed our domestic in-roof 16 panel solar system and battery system in November 2024. Unlike some competitors who expect you to separately find and arrange scaffolding and roofing work, ESS managed the whole project from start to finish using their own staff and trusted sub-contractors. This included: * scaffolding, * roofing strip, * panel and battery installation, * reroofing, * scaffolding removal, * all related electrical work, * commissioning, certification and documentation, * registration with UK Power Networks, and * payment of all sub-contractors. All we've had to do since is arrange a new generation tariff with the utility company. The price paid was the price agreed at the outset. There were no unexpected extras. We would thoroughly recommend ESS for their professionalism. Everyone working on the project was polite and well informed. The work was undertaken when promised (despite some foul weather) with all contractors arriving and working as and when promised. It's still a bit too early to work out in detail how much we are saving and making, that's going to take a year or so. However, even on dull days in mid winter when the days are short and the sun is lowest the panels generate some power. The battery means we now buy and save cheap power overnight at off peak rates and avoid drawing from the grid at high peak times.
