Heatable install solar panels, UK wide. They are a Which? Trusted Trader, so have passed the rigorous assessment set by our trading standards professionals. We selected Heatable as the Trusted Trader we would partner with on this promotion because of the quality of the offer.

When you go to the Heatable website using the link on this page, Heatable will first ask for the email address you have used to subscribe to Which? with. You then have two options. You can either use Heatable's online 3D mapping tool to understand how many panels you can fit and what savings you might see before enquiring further, or you can book an appointment straight away. If you go ahead, the team will complete a full MCS system design and then plan for installation with you, if Heatable have confirmed that your house is suitable for solar panels.

Which? will receive a commission from Heatable once installation has been successfully completed. Part of the commission helps fund our mission to continue as the UK’s consumer champion.
