Tethys Energy Ltd

We chose Jason for his calm efficient manner, responsiveness and evident knowledge. This wasn't an easy installation; the building's listed so panels had to go on an outbuilding with cabling to the house causing lots of challenges setting up in a very old building. So we went back and forth for ages with quotes and planning, then getting the job done and Jason was unbelievably patient throughout. Everything happened on time and on budget, and he was great with all the admin follow up afterwards and responsive glitch solving (ones caused by us not him). Definitely recommend.

Great work. I would totally recommend Tethys to install solar panels. The work was completed very efficiently. Very helpful explained how the system works and I have an app to monitor the daily energy generated.

We chose Tethys Energy after talking to three good installers, partly because of good reviews but, on meeting owner Jason Fuller, we felt confident that he would be someone we could trust and work with. He was flexible when discussing the specification of the installation as we were keen to use better quality components.Tethys quotation was very fair and they did exactly as they promised. In spite of appalling weather, the job was completed on time and as specified. We recommend Tethys highly.

Excellent workmanship in fitting and installing 18 solar panels and battery, and fantastic patience with initial consultation regarding makes and models of solar panels and of types of battery. Always turned up on time and gave plenty of notice on dates of installation, plus kept updated on progress of approval of installation from UP Power networks. Very highly recommended.

Jason really knows his stuff. He explained the complications of installing solar panels thoroughly and clearly, Preparations for and the carrying out of the installation were immaculate. He was always available to answer queries and prepared to go the extra mile - for instance he found us a buyer for the slates removed from our roof. If there are issues later we are sure that he will provide all the advice he can. If only all traders were like this!

Used Jason after hearing about his company from an ex-colleague. Initially, Jason provided me with a quote and was very patient in discussing the figures with me as I was not an expert on the subject. It all looked very good but due to family circumstances we did not go ahead. Jason left us to make our decision in our own time and no pressure was bought on us. When our family issues subsided I contact Jason again and he pulled out the stops to do the installation before the critical date of end of March. All work was carried out in a very professional manner. In fact whilst on the roof, Jason noticed some issues with some of the tiles and fixed them. Also indicated there was more work that would be beneficial to be done whilst there was scaffolding in place. I contacted a roofer who came and fixed the problem. The panels were installed on time with the supporting equipment. Jason then provided support in getting the installation registered. The panels are working and we are very happy. Lastly, Jason provided an insurance policy to protect my deposit and also support in the future should his company cease trading. I have no doubts in recommending Jason.

Jason Fuller at Tethys Energy really knows his stuff. You can go through sales reps reading from scripts at call centres or else you can call Jason and talk directly to the guy who understands the technology and the admin and who actually does the work, and at a very competitive price, too. He always went the extra mile to make sure everything was exactly right. The installation could not have been done more professionally, and it is now working beautifully. I highly recommend.

Very good experience. Quotes were very detailed, with clear optional areas. From order to delivery was clearly project time scaled . Installation over 2 days went very smoothly, and system up and running with no problems.

I got in touch with Tethys Energy after reading the positive reviews. Everything after that was very professionally done, from putting my deposit into a holding account with insurance, to consultation, design and build. I am a techie, so I wanted to see how can we tailor the system to my specific needs, and Jason has been an excellent partner in giving advice and making recommendations. All stages of the installation were organised and carried out like clockwork. Finally all the boring part with the registration, getting signed up for the feed in and export tariff etc has also been done by Tethys as much as possible (some of the paperwork has to be done by the owner, but that cannot be helped). The final result is great, and we are very happy with it.
