Are there grants for home batteries in the UK?

There is not one single grant in the UK that gives every homeowner money for buying a home battery. But there are still several ways to get financial support or reduce the total cost.

Some households can receive battery storage as part of a wider energy-saving scheme, while others can benefit from tax relief or lower energy costs after installation.

The support available depends on multiple things like your income, where you live and the type of system you want to install. Different schemes can also apply in England, Scotland, Wales and Northern Ireland. Because of this, it is worth looking at the different options before buying a battery.

What grants are there for people with low-income households?

Warm Homes: Local Grant

Low-income households (below £36,000) usually have the best chance of receiving financial support. One of the main schemes in England is the Warm Homes: Local Grant. This is aimed at households with a lower income and homes that are not very energy efficient. If you qualify for the grant, your local council may help with improvements such as insulation, solar panels and in some cases battery storage.

ECO4 scheme

Another option is the ECO4 scheme, which runs until the end of 2026. ECO4 helps lower-income households make their homes more energy efficient. Support can include insulation and sometimes solar panels or battery storage as part of a wider package.

In what other ways can you save money when buying a home battery?

Save through the current VAT rules

Even if you do not qualify for a grant, there are still other ways to save money. One of the biggest benefits is the current 0% VAT rate on qualifying home battery installations until 31 March 2027. This can apply when a battery is installed with solar panels, added to an existing solar system or installed on its own. You can read more about this in our guide to 0% VAT on home batteries in the UK.

Avoid paying for unused capacity

Choosing the right battery size can also save you money. A larger battery is not always better. If you buy much more storage than you actually need, part of the battery may hardly be used. A battery that matches your daily electricity use can often give better value for money. Use our home battery capacity calculator to make sure you get the right size battery.

What grants and other upcoming funding will be available in the UK?

More financial support for home energy systems is expected in the next few years. One of the main plans is a government-backed loan scheme for things such as solar panels and home batteries. The idea is to make these systems easier to afford by allowing households to spread the cost with low-interest or possibly zero-interest loans.

Planned home energy finance

This scheme is expected to start in April 2027. The exact terms are not yet fully known, so things such as the interest rate, maximum amount and eligibility rules could still change before it starts.

Boiler Upgrade Scheme

There is also a planned £2,500 grant for thermal batteries through the Boiler Upgrade Scheme. A thermal battery is different from a normal home battery. It stores heat for your heating and hot water rather than electricity for your home.

Before you buy

Use the savings available today

For most people, the best way to save on a home battery is not to rely on one specific grant, but to combine the main ways to save money that are already available. This could mean using 0% VAT, choosing the right battery size and making the most of your own solar power or cheaper electricity rates.

Check the latest support before buying

The options are also likely to improve over the next few years, as new funding and loan schemes are expected in 2027. Because of that, it is worth checking the latest support before you buy a home battery, as the total cost can be very different depending on the scheme you can use.
