Tethys Energy Ltd

Tethys Energy did a fantastic job on our recent roof-integrated solar and home battery home battery installation. Every stage of the process was straightforward, well communicated and they clearly know their trade. We couldn't be happier with the service and end result.

Tethys Energy responded to my request for a quote for solar panels and battery. Jason was very responsive, happy to engage in a dialogue about his proposal and to discuss the pros and cons of alternative approaches that had been proposed. Jason's whole approach made it very easy to choose Tethys. The implementation was managed by Chris, who along with the rest of the team and not forgetting Louise in the office, were always professional, friendly and easy to deal with. The implementation was even completed slightly ahead of schedule. I'm pleased I chose Tethys, would happily go to them again and would recommend anyone looking at a project like this to talk to Tethys Energy.

Tethys Energy started with a comprehensive survey and quote and were very knowledgeable. They are professional and communicated well throughout the process. The team worked hard and delivered a fantastic, smooth end result. I'd happily recommend.

We were very happy with all of Tethys Energy's work and feel they really deserve their excellent reputation. We felt confidence in them during the whole process. We are very happy we chose them.

Contacted Tethys Energy about installing solar and battery storage at my home. Jason Fuller promptly gave me a outline of what would be feasible by e-mail and then came round to undertake a full survey, followed by a proposal with a full breakdown of costings. Installation by Chris and the team was excellent and completed ahead of schedule. The system has performed exceptionally well. Importantly, all the installation documentation and certificates plus DNO connection agreements were sent promptly after completion. Very happy to recommend to others

Tethys fixed my solar problem

I had a problem with my panels which Tethys correctly diagnosed and rectified. They were helpful and proactive throughout. I will definitely use them again

We used Tethys Energy - excellent work

We used Tethys Energy to add an additional battery to our solar power system. They were not the original system installers, who I had invited to quote but who were very expensive. The price from Tethys was much more reasonable. I was impressed with the thoroughness of the checks that Jason Fuller, the MD, did before he committed to do the work. When his guys did carry it out they were pleasant to deal with and neat in their workmanship. The enhanced system works perfectly. I would be very happy to use Tethys Energy again if I were to expand or replace my solar system. They inspired my confidence and they didn't let me down.

Excellent solar installation.

We are very happy with our solar installation. Tethys are quick, efficient, informative and friendly. We recommend Tethys Energy to one and all! Absolutely first class!

Absolutely delighted - personalised service

I am delighted to be given the opportunity to review Tethys Energy, and his manager, Jason. From the beginning, Jason answered my innumerable questions, tailored the solution to my needs, and deployed the perfect solution, with top quality workmanship. Some other people pretend to be able to design a solar & battery solution remotely, but rather, Jason came to my house to assess with his own eyes. It gave me confidence of a job well done. There were issues with the commissioning of the battery, but he persisted, chased the supplier and duly got it to work - I was in good hands from start to finish. The inverter in the loft is discrete, the controller on the side of the house is discrete and so is the battery in the garage; all positioned to be the least in the way possible. I have been enjoying the solution since April 2024 without any issue whatsoever. Thank you Jason and team !
