Who can apply
All homeowners, including landlords, whose homes were built and occupied before 2021 can apply. This is defined as the date your electricity meter was installed. This is different to other grant measures where the home must be built before 2011.
Important compliance check
This type of grant is based on the energy upgrade being applied to your entire home. The solar thermal system should be based on the average number of people that could live in a home of your size. It should not be based on the number of occupants.
Your registered contractor should carry out this compliance check before work starts. Failure to comply may result in the grant not being paid.
For further information read our Solar Technical Guidance and Compliance Calculator.
When installing a solar thermal system the total collector area must not exceed 12m2 or 50% of the home’s total roof area. Otherwise planning permission will be required. We recommend that you discuss this requirement with your registered contractor.
