Based on 80+ clients: 4.5

I used SolarTherm to fit a battery for my solar panels. I cannot fault the customer service, the install or the fitter. They were easy to deal with, explained everything to me and answered my questions confidently. I would not hesitate to recommend SolarTherm to anyone. Brilliant products and company. Thank you.

Leann R.

From the initial consultation period to installation was an easy process. Everything was explained in great detail and the team were more than happy to answer any questions that I had. The installation took a whole day to complete and again everything was explained to me in great detail on how the system was installed, how it operated and how I monitored the output from the newly installed panels. The installation was done to a very high standard and very neat with no visible cables showing. I would recommend SolarTherm UK if you are considering having solar panels installed.

Lily did a great job working through our design with us and was very patient as we went through the options. Malcolm the surveyor was very knowledgeable and put us at ease prior to installation. The installation team Jude, Ben and Matthew were very efficient, very neat tidy work with some tricky cabling. Hillary has been very helpful on the technical side and is walking us through the set up with our energy provider. All round very impressed with the efficiency of service and attention to detail so far. Thank you!
