Solar Battery Storage Grants and Schemes

If you’re thinking about adding battery storage to your solar setup, government grants and local schemes can make the switch more affordable. Whether you’re a homeowner, a business, or part of a community project, there’s support available to help you store the energy your solar panels generate and make the most of it. See who qualifies, how to check, and what support might be available.

Are There Any Grants Available for Battery Storage in the UK?

There are still government-backed ways to get support for home battery storage in 2026. If your home meets the eligibility criteria, you could receive free or significantly reduced-cost battery installation.

Even if you’re not eligible, there’s still a clear, supported path forward. Switch Together helps households across the UK access lower-cost battery systems, expert guidance, and in some areas, financing support—all in partnership with local councils.

If You’re Not Eligible for Government Grants

Not every home qualifies for government funding — and that’s okay. You can still reduce the cost of going solar by switching together with others in your community.

That’s where Switch Together comes in. We use group buying to bring households together, helping you access competitive solar offers from trusted installers — without relying on grants.

Frequently Asked Questions About Battery Storage Grants

For the most accurate, up-to-date guidance, always check the official government websites.

Can I apply if I already have solar panels?
Yes! Many battery storage grants support adding a storage system to an existing solar setup. You can usually qualify if you’re installing a new battery, but grants generally aren’t available for replacing older batteries or systems that were already fully funded.
Do I need to repay my battery storage grant?

No. Grants are financial support, not loans, so you won’t need to pay them back.

Can I combine a battery grant with other savings or offers?

You can sometimes combine government-backed grants with additional savings, like group-buying schemes through Switch Together.

Can landlords apply for battery storage grants?

Sometimes. Eligibility depends on the scheme. Some local authority programmes may allow landlords to apply, but most schemes primarily support owner-occupiers.

What if I’ve already applied for another battery grant?

You can apply for multiple grants, but you can’t use more than one grant for the same battery installation. If a system has already been funded, you won’t be able to claim again for the same upgrade.

Do business battery storage grants exist in the UK?

Yes. There are schemes designed for businesses, including innovation or commercial deployment programmes. These often support larger installations or pilot projects.
