Who can supply & fit ThermaTwin?

Over 3,000 ThermaTwin panels have been successfully installed over a 13 year period; many of them self-installed DIY projects.

However, to qualify for RHI (Renewable Heat Incentive) grants and payments, the Solar Thermal panels must be installed by a certified MCS accredited installer.

If you are interested in the ThermaTwin system and you would like to receive a free site survey and quotation from one of our registered installers please contact us using the form here.

ThermaTwin systems are usually installed for around £2,800* (incl. 5% VAT) and can be fully fitted within 1 working day. The installation process causes minimal disturbance to neither the roof nor internal loft space. Usually no replacement tank or thermal store is required, but if the existing cylinder is past its useful life, or is very poorly insulated, you may be expected to replace the old cylinder for a new one to qualify for any grants or fee in tariffs (FiTs).

* Standard 2 storey building installation with access.
