Whoever supplies your electricity, you may be able to apply for the Free Home Battery Scheme. Eligible private households can apply for a home battery installed at no cost, with up to £500 per year towards electricity bills, subject to scheme terms.
Check if your home qualifies for a free battery
Homeowners and private tenants can apply. It only takes a few minutes.
The Free Home Battery Scheme described on this website is not an EDF scheme. Your electricity supplier is separate from the organisation providing and operating the battery programme.

EDF and home battery storage
Checked 30 September 2026. Tariffs and products change — check with EDF before deciding.
EDF bought solar and battery installer Contact Solar in February 2024 and now sells solar panels and batteries under EDF’s name across England, Wales and parts of Scotland. Systems are bought outright. EDF also lists a “carbon cashback” offer that depends on eligibility.
If you were looking for Sainsbury’s Energy: it’s now supplied by E.ON Next, not EDF.
Empower tariffs for battery homes
Checked 30 September 2026. Tariffs and products change — check with EDF before deciding.
EDF’s Empower Fixed tariffs are aimed at homes with solar and a battery and include a discount on overnight battery charging. Empower Fixed Exclusive goes further for people who bought solar or a battery from EDF on or after 2 March 2026, with an offer of £0 electricity bills for 12 months when we checked. Both need a smart meter with half-hourly readings.
EDF’s export tariffs likewise pay more to customers whose system came from EDF than to existing panel owners. Read how tariffs affect what a battery can save for why cheap-rate charging matters.
GoElectric, Weekend Saver and Kraken
Checked 30 September 2026. Tariffs and products change — check with EDF before deciding.
GoElectric is EDF’s EV tariff with a cheap overnight window. EDF also runs a Smart Charging bolt-on on the Kraken platform.
In November 2025 EDF and Kraken announced a flexibility partnership: with the customer’s consent, EDF can automatically shift EVs, solar, home batteries and heat pumps. We couldn’t confirm a battery-specific product built on it.
EDF’s rewards pay out in free hours of electricity: Sunday Saver, and the Flextras loyalty scheme launched in September 2026 around Weekend Saver, reward low weekday use between 4pm and 7pm. Weekend Saver excludes time-of-use tariffs.
Does my energy supplier matter?
The scheme is open to private households, whether you own your home or rent privately (with your landlord’s approval before installation). Tell us who supplies your electricity in your application — your home’s suitability is then confirmed through the application and the home survey. Read who can apply or how the scheme works.
Free Home Battery Scheme vs buying a battery
Free Home Battery Scheme
- Battery supplied through the scheme
- £0 battery installation for eligible households
- Scheme owner keeps ownership of the battery
- Scheme owner maintains, services and insures it
- Scheme owner replaces it where required
- Scheme owner handles end-of-life disposal or recycling
- Up to £500 a year towards electricity bills, subject to scheme terms
Buying your own battery
Buying a battery generally means you pay for it (upfront or on finance) and own the equipment, subject to the supplier or installer’s terms, warranty and tariff conditions.
EDF sells and installs batteries through Contact Solar, which it acquired in 2024. When we checked, a 5.32kWh battery was listed from £3,995 including an inverter and installation. You buy and own the system.
Neither route is right for everyone: owning a battery gives you full control over it and any tariff you pair it with, while the scheme removes the upfront cost and ongoing responsibility.
Could your home qualify for a free battery?
It only takes a few minutes to start your application.
EDF and home batteries: FAQs
Does EDF have a free battery scheme?
We haven’t identified a current one. EDF sells batteries through Contact Solar and has offered discounts in the past, but not free batteries.
Is the Free Home Battery Scheme run by EDF?
No. It isn’t connected with EDF or Contact Solar, and EDF doesn’t operate, fund or endorse it.
Can EDF customers apply for the Free Home Battery Scheme?
Yes. Being on GoElectric, Empower or a standard EDF tariff doesn’t stop you applying. Mention your tariff in the application.
What is EDF Empower?
A set of fixed tariffs for solar and battery homes that discounts overnight battery charging. The Exclusive version is for people who bought their system from EDF on or after 2 March 2026.
Can a battery help with EDF Weekend Saver?
Weekend Saver rewards keeping weekday 4pm–7pm use low, which a battery can help with by covering that period. Check EDF’s terms: time-of-use tariffs are excluded.
