Everything you need to know about the Free Home Battery Scheme in one place. The short version: homeowners with solar panels, or getting them, can apply (everyone else can join the waiting list), the battery is installed at no cost, participating households could save up to £500 per year on their electricity bills, and the scheme owner owns, maintains, services and insures the battery.

About the scheme

Is the home battery really free?

Yes. For eligible households, the battery is supplied and installed through the scheme at no cost. The battery remains owned by the scheme owner, who is responsible for maintaining, servicing, insuring and, where required, replacing it.

What is the Free Home Battery Scheme?

A programme that installs smart, connected home batteries in private homes at no cost to eligible households. Participating households could save up to £500 per year on their electricity bills, subject to eligibility and scheme terms.

How the scheme works

Why are free batteries being installed?

The programme is intended to create benefits at both household and electricity-system level. By deploying connected energy storage into homes, it aims to help reduce household energy costs, support the electricity grid and contribute towards greater energy security.

Who can apply

Who can apply?

At the moment the scheme is open to homeowners whose home has solar panels, or is getting them through any funding scheme or finance. Renters and homes without solar can apply to join the waiting list. Every home also needs a survey to confirm it is technically suitable.

Who can get a free home battery

Do I need to own my home?

For now, yes. The scheme is currently open to homeowners only. If you rent, privately or in social housing, you can still apply and join the waiting list for when the scheme opens more widely. Your landlord’s permission would be needed before any installation.

Batteries in rented homes

Do I need solar panels?

For now, yes. The scheme currently fits batteries alongside solar panels. If you don’t have solar, you can apply and ask to discuss solar funding or finance, or join the waiting list for battery-only installations.

Batteries without solar panels

Can the battery be added to solar from another scheme or finance?

Yes. The solar panels don’t have to come through the scheme. If you’re having solar fitted through another funding scheme or with finance, such as the Warm Homes Plan or a solar panels grant, the battery can be added to that installation.

Batteries and solar funding

Do I need a smart meter?

Yes. If you don’t have one, ask your energy supplier: they will install a smart meter for free. You need to arrange this with your supplier yourself.

Can I apply if I already have solar panels?

Yes — tell us in your application. How a battery would work alongside your existing system is considered during the survey.

What happens if my property isn’t suitable?

If the survey finds your property isn’t suitable, the installation won’t go ahead. You won’t have paid anything to apply or for the survey.

The battery

How does a home battery work?

A home battery stores electricity so it can be used later. Smart controls decide when it charges and discharges — typically charging when demand is lower and releasing energy when demand is higher.

How home batteries work

How large is a home battery?

Home batteries are usually a single sealed unit, often wall-mounted. Their storage capacity is measured in kilowatt hours (kWh).

Where can a battery be installed?

Home batteries are commonly installed in places such as a garage, on an outside wall or in a utility space. The right location for your home is agreed at the survey.

Can a battery be installed in a garage?

Garages are a common location for home batteries. Whether your garage is suitable is assessed at the survey.

Why does the battery need an internet or mobile connection?

The battery is a connected battery, managed as part of the programme alongside other homes. A connection lets it receive instructions about when to charge and discharge.

Survey and installation

What happens during the home survey?

A surveyor checks whether your property and the proposed battery location are suitable, looking at the electrical installation, connectivity, access, safety considerations and what the installation would involve.

What to expect at your survey

Who installs the battery?

An approved installer completes the battery installation.

Will my electricity be switched off during installation?

Connecting equipment to your electrical installation usually needs the power to be turned off for part of the work.

Money

How much could I save on my electricity bills?

Participating households could save up to £500 per year on their electricity bills, subject to eligibility and scheme terms.

Can a battery reduce bills?

Are the savings guaranteed?

No. The amount is “up to” £500 per year and depends on eligibility and the scheme terms, so actual savings vary with tariff, electricity use and solar generation.

Ownership and maintenance

Who owns the battery — does it belong to me?

The battery remains owned by the scheme owner. It does not belong to the homeowner simply because it is installed at their property.

Who owns and maintains the battery

Who maintains the battery?

The scheme owner is responsible for maintaining and servicing the battery.

What happens if the battery needs replacing?

The scheme owner is responsible for repairs and for replacing the battery after 10 years.

Do I need to insure the battery?

The scheme owner is responsible for insuring the battery.

What happens to the battery at the end of its life?

The scheme owner is responsible for the appropriate removal, safe disposal and/or recycling of the battery when required.

What happens if the battery develops a fault?

The scheme owner is responsible for maintaining and servicing the battery.

Moving house

What happens if I sell my home?

The household agreement can be transferred to the new owner. The scheme owner keeps owning the battery and stays responsible for it.
