Current Funding Options for Solar Installations
In the UK, the main national incentive for solar PV is the Green Homes Grant, which ran from 2020 to 2021 and offered up to £10,000 per household. Although the program has closed, its legacy funding can still be accessed through remaining local authority reserves or partner charities. Additionally, the Renewable Heat Incentive (RHI) provides payments for solar thermal systems that generate hot water, paying households a set amount per kilowatt‑hour of heat produced over a 13‑year period. The RHI remains active and is open to all domestic and commercial users.

Beyond national schemes, many local councils offer additional grants, rebates, or low‑interest loans for solar panel installation. These vary by region and are often tied to local sustainability targets. For example, the London Borough of Brent provides a £5,000 grant for community solar projects, while the Scottish Government's Clean Energy Scotland program offers grants for small‑scale solar on homes and farms.
Eligibility Criteria and Application Process
Eligibility for the Green Homes Grant required a minimum of two new solar panels, a 5‑year maintenance agreement, and a certified installer. The RHI applies to systems meeting the UK's Energy Savings Opportunity Scheme (ESOS) standards, and applicants must submit a detailed energy assessment before installation. Local council schemes often require proof of energy usage, a site survey, and sometimes a community benefit statement.
Applications typically begin with an online portal where you upload proof of purchase, installer credentials, and a site assessment. For the RHI, the Department for Business, Energy & Industrial Strategy (BEIS) provides an online form that calculates projected payments. Local schemes may use their own forms or partner with third‑party providers like the Solar Trade Association's Solar Grants Finder.
Timing, Funding Limits, and Future Outlook
The Green Homes Grant has closed, but the RHI is scheduled to continue until 2026, with potential extensions depending on policy shifts. Local grants are less predictable; they can change annually based on council budgets and national funding allocations. Emerging technologies, such as battery storage, may open new grant categories in the near future as the UK pushes toward net zero.
To secure funding, homeowners should start by contacting their local council's energy department, checking the RHI eligibility calculator, and ensuring their chosen installer is accredited. Maintaining a record of all receipts and certificates will streamline the grant submission and audit process.
