Solar panel grants in 2026: do you qualify and how to claim
There is no single nationwide cash grant that pays for solar panels for every household in 2026. Instead, qualifying solar carries 0 percent VAT until 31 March 2027, lower-income homes may get help through ECO4 or the Great British Insulation Scheme, and the Smart Export Guarantee pays you for exported power.

Get matchedWhat it is
When people search for a "solar panel grant" they usually mean one of three different forms of support: a tax saving everyone gets, means-tested funding for eligible households, and a payment for the electricity you export.
Knowing which applies to you matters, because the rules and the application routes are completely different. This guide separates them so you do not chase a grant you cannot get.
How it works
The 0 percent VAT relief is automatic: a qualifying installer simply does not add VAT to the bill for eligible work completed by 31 March 2027.
ECO4 and the Great British Insulation Scheme are means-tested. Eligibility is based on income, benefits and the energy efficiency of your home, and funding is delivered through obligated energy suppliers and their approved installers.
The Smart Export Guarantee is not a grant at all but an ongoing payment: once your system is MCS-certified, you apply to a licensed supplier who pays you for surplus electricity you export.
Who it is for
- Any homeowner installing qualifying solar before 31 March 2027 benefits from 0 percent VAT.
- Lower-income or benefit-eligible households, and those in less energy-efficient homes, should check ECO4 and GBIS eligibility.
- Everyone with a system installed should register for an export tariff to be paid for surplus power.
Grants and savings
- 0 percent VAT on qualifying solar panels until 31 March 2027, then set to revert to 5 percent (gov.uk).
- ECO4: means-tested support for energy-efficiency measures in eligible homes, delivered by obligated suppliers (Ofgem).
- Great British Insulation Scheme: further means-tested help with insulation and related measures (Ofgem).
- Smart Export Guarantee: payment from a licensed supplier for surplus electricity you export once MCS-certified (Ofgem).
How to choose a vetted installer
- For grant-funded work, the installer should be TrustMark-registered as well as MCS-certified, since government schemes require TrustMark.
- Be cautious of cold callers promising "free solar". Genuine schemes are means-tested and delivered through approved installers, never doorstep sales.
- Confirm in writing which scheme is funding the work and what you would pay if a grant is not approved.
Frequently asked questions
Is there a free solar panel grant in 2026?
There is no universal free-solar grant. Means-tested help may be available through ECO4 or the Great British Insulation Scheme for eligible lower-income households, and all installs benefit from 0 percent VAT until 31 March 2027. Beware "free solar" cold callers.
How do I check if I qualify for solar grant funding?
ECO4 and GBIS eligibility is based on income, benefits received and your home's energy efficiency. Check the criteria on Ofgem and apply through an approved, TrustMark-registered installer rather than a doorstep salesperson.
Does the Smart Export Guarantee count as a grant?
No. The Smart Export Guarantee is an ongoing payment, not a one-off grant. Once your solar system is MCS-certified, a licensed energy supplier pays you for the surplus electricity you export to the grid at their published rate.
