we handle everything in house

Unlike many solar panel installation companies, SolarTherm UK manages every stage of your project in-house, without outsourcing. From the initial solar PV system design and specification through to scaffolding, supply and installation, we provide a complete turnkey solar solution with a seamless, hassle-free experience.

We work with leading solar panel, inverter and battery storage manufacturers to deliver bespoke solar energy systems tailored to your property and energy requirements. Thanks to our extensive stock holding at our Basildon headquarters, we are also able to offer fast turnaround times for both domestic and commercial solar installations across Essex and the South East.

This company fitted our solar panels two weeks ago. They’re a professional set up – all the engineers were very knowledgeable and took care to walk me through the installation process. Equally, the back office staff were supportive in overcoming the one or two issues that tend to come up in building works. Two weeks after the build, I’m very happy with the quality of the work and the customer engagement throughout.

Super happy with the service we got from SolarTherm. Very helpful and quick delivery for our solar battery – would recommend and use them again in the future. Thank you.

Just had a new solar system installed (11 panels and 2 batteries). Must say I was very impressed by the professionalism and quality of this company. Everything happened as it should have done. All the people from office staff to installers seem to know their subject well and everyone without exception was very pleasant to deal with. No hesitation in recommending them to others and I already have.
