GESS

We had an excellent experience with GESS — the whole process was incredibly quick and efficient. RICHARD came out to give us a quote (with couple surveys), and GESS came out interesting and cheapest with the most panels. Best of all, they were able to install the following week after the signed documents (in the coldest day of November).They handled everything: application was sorted quickly, scaffolding went up without a hitch. The team came over to do the survey and took the time to walk us through exactly how the system would work, which really helped build our confidence in the setup.Richard and all the team was brilliant throughout — always quick to respond, really knowledgeable, and happy to answer all our questions. The installation itself was seamless.Great service, great communication, and a really smooth experience from start to finish. That’s GESS Highly recommended!

After 4 Quotes for solar and battery Gess were by far the cheapest so initially it did raise a red flag, I need not have worried the service I received for this company was exceptional from the initial consultation with Harrison then right the way through the insulation process.Communication was great I was kept informed of the process throughout, scaffolding, certification and installation.On the day of installation the fitters arrived on time and went through the fitting of the system all the time making sure I was happy with the location of the equipment and the cable runs and finally spending time running me through both the App on my phone and the battery system.Finally I would just like to say a massive thank you to Gess for making my solar experience a seamless and enjoyable one, all your staff have been so helpful and are a credit to your company.Would I recommend you to my friends 100 percent.Many ThanksBradley.

Despite the installation going more or less to plan, since then their service has dropped off a cliff. It took over a month for snagging to be completed and two months later there has been no handover. Despite assurances of an annual service, and repeated emails on that subject none is forthcoming. I would think very hard before committing to them for works.

First class service from the GESS team from start to finish ! Panels and Tesla Powerwall linked to Octopus is a perfect combination! Thoroughly recommended. Call them now !

The communication from Gess was easy and efficient, and the arrangements were clear. The installation was quick, and the installers were friendly, knowledgeable and informative. I was really pleased with the whole experience, and the system appears to be delivering the results I wanted. Early indication is that I will get payback for my investment within 8 yearsPaul Dawson, East Ham London

I had both Solar Panels and ASHP installed. First the solar panels inverter and battery were fitted followed by the ASHP which required a replacement of some radiators and some new ones to meet the heat survey. All trades worked well together and as promised we were only with hot water and heating for half a day. I would highly recommend this Company as the sales and office support was as good as the technical phase

A very good service and installation by GESS the whole team from the office to the install where greatWould highly recommend Gess where not the cheapest quote , but delivered what we wanted to perfection .we felt very comfortable using a company with 13 years experience

Good communication throughout my experience. Always ready to answer any questions after installation. Very happy with this company would recommend.

I had a terrible experience with Green Eco Solar Solution (GESS) regarding my solar panel and Tesla Powerwall 3 installation. GESS provided a quote, which I accepted, and I paid a £500 deposit. I made it very clear that the council had revoked permitted development rights for new developments, meaning I needed to obtain planning permission. GESS agreed to wait for this. The contract was signed, and I was assured it was legally binding. A technical survey was conducted twice, and I was informed that everything was in order. Once I secured planning permission, GESS was unable to schedule the installation until February 2025.Then, in January 2025, they claimed that the quoted price was subject to change at any time and that they could no longer proceed at the originally agreed price.Despite the agreed quote, completed site surveys, signed contract, and deposit payment, GESS attempted to impose additional charges outside the contract. When I refused, they unilaterally cancelled my installation and refunded my deposit without my consent—an outright breach of contract. Communication was poor, with long delays and ignored emails. My Tesla account now shows two Powerwall 3 units registered under my name, adding further complications. This is completely unacceptable, and after escalating the matter, I received the following response from GESS:"Site surveys had identified increases in works required for your system, including ridge work, panel orientation and design, along with scaffolding requirements."I would not recommend this company due to their lack of professionalism and integrity.

Excellent service. Installed solar panels and battery. Workers were very efficient and nice people. I do recommend this company. Nice to do business with pleasant and accommodating people!
