Lower energy costs, local impact with Battery Boost.
We believe a greener energy grid shouldn't come at a cost to you.
What's Battery Boost?
Our current energy system is under pressure during peak demand, but we’re working with grid companies to build a smarter, greener network that you can be a vital part of. By joining, you get a fixed monthly bill credit while helping the local grid get the balance it needs—it’s a win-win that starts in your home.

We take the complexity and the cost out of home battery storage.
We've made Battery Boost completely effortless and no cost for you, as we fund the E.ON Next-owned home battery, its installation, and maintenance. We manage the battery entirely to help the grid, and in return, you receive a guaranteed fixed credit on your bill every month and you'll only pay for the energy you use at a low fixed rate.
Real savings, zero effort.

Battery Boost FAQs.

We select locations based on grid requirements and local demand. By registering your interest, you ensure you’ll be the first to know when your area is chosen. Our first trial locations will be announced during the summer of 2026.
What will I receive as part of Battery Boost?
Accepted participants will receive a minimum credit of £10 per month. The exact amount, along with tariff details, will vary by location and will be confirmed before you decide whether to proceed. For context, previous participants in North Yorkshire and Lincolnshire received a £40 monthly credit and a bespoke electricity tariff benchmarked against the lowest available E.ON Next regional rate.
How big is the battery, and where is it installed?
Our largest batteries are roughly the size of a large suitcase (115cm x 60cm x 28cm). They are typically mounted on an external wall, though in some cases, they can be installed in a garage or utility room.
Do I need to do anything to operate the battery?
No. We manage the battery entirely on your behalf—no apps or in-home displays are required. Occasionally, we may request a visit at your convenience to perform routine maintenance or system checks.
Are there any additional costs?
No. The survey, equipment, installation, and ongoing maintenance are all provided at no cost to you. The only potential charge is an exit fee if you cancel the agreement within the first year.
What happens if I move or want to cancel my Battery Boost tariff?
After the first 12 months, you can cancel your agreement for free, and we will remove the battery at no cost. If you choose to cancel within the first 12 months, an exit fee applies to cover the initial installation costs. Specific fee details will be provided when Battery Boost launches in your area.
Does it cost anything to join the waitlist?
No. Registering your interest is completely free and carries no obligation to proceed.
