What is Battery Boost, and what did E.ON Next announce?
Battery Boost is an E.ON Next scheme that fits a home battery to the outside of your house at no upfront cost and pays you a fixed credit on your energy bill each month. On 10 November 2026 the supplier said it’s expanding the scheme with three electricity network operators and putting £4 million into 1,000 more batteries.
The three operators are named in the release as Northern Powergrid, SP Electricity North West and UK Power Networks. E.ON Next says the batteries are aimed at homes across north Lincolnshire, Yorkshire, the east and north east of England and Greater Manchester, and particularly at households at risk of fuel poverty.
Most people assume a battery is only for homes with solar panels. E.ON’s own research, quoted in the release, found 73% did not know a home battery works without solar panels. Battery Boost is built on exactly that idea.
Key takeaways
- Battery Boost puts a home battery on your wall with no upfront cost. E.ON Next owns it, fits it and maintains it.
- The sign up page offers a credit of £20.83 a month, which it puts at £250 a year. Exit fees and terms apply.
- You need to be a homeowner on an E.ON Next electricity tariff, with outside space and no solar panels, EV charger or heat pump.
- Places are limited to 1,000 batteries in this rollout.
How does Battery Boost work?
The battery charges overnight, when demand on the grid is lower. During the day your home runs on that stored power through the peak hours, and E.ON Next exports any surplus when the grid needs it. You don’t press anything. E.ON Next’s smart technology manages the settings and charging schedule, and the page says you won’t have direct access to a control portal, so what you see is the credit on your bill and a new line for electricity sent back to the grid.
In return you get a fixed credit of £20.83 on your bill every month, and you pay for the energy you use at a fixed rate. The credits only start once E.ON Next has received an export MPAN from your distribution network operator, which its page says typically takes up to four weeks after installation. That’s the deal as E.ON Next’s own page describes it. The battery is working for the local network as much as for you, which is why the network operators are involved at all.
The unit is a Fox ESS Evo All-In-One System with 10.24 kWh of storage and a 10 year manufacturer warranty, according to the same page. It’s roughly the size of a large suitcase, 58.4cm wide, 109.9cm high and 19.7cm deep, and E.ON Next says it’s fitted outside for most homes, away from direct sunlight and not on a south facing wall.

How much could Battery Boost save you?
There are two different numbers in circulation, and they aren’t the same thing. The sign up page offers £250 a year in bill credits. The press release says the first households are “saving hundreds of pounds a year”, and E.ON UK’s chief executive Chris Norbury says previous customers are “nearly £500 a year better off”.
The release doesn’t explain the gap between the two. The £500 figure describes households in E.ON’s earlier project, in the company’s own words. The £250 figure is what the current offer puts in writing. If you’re weighing it up, use the number on the page you’d be signing, and treat anything above it as an estimate that depends on your home and your tariff.
Both figures are E.ON’s. Nobody independent has published results for the scheme that we could find.
Who can get a Battery Boost battery?
E.ON Next lists four requirements. You need suitable space outside for the battery. You need to be the homeowner, with a working smart meter or a willingness to have one fitted. Your home can’t already have solar panels, an EV charger or a heat pump. And you need to be an E.ON Next customer, or switch to an E.ON Next electricity tariff before joining.
Registering is a waitlist, not a contract. E.ON Next checks eligibility, then arranges a free survey if your home looks suitable. Its Battery Boost page says the scheme is supported by the fuel poverty charity National Energy Action.
Renters are out for now, since you have to own the home. So is anyone who has already gone electric with a heat pump or a car charger, which is a slightly odd club to be excluded from.
What are the catches?
The battery isn’t yours. E.ON Next owns it and controls when it charges and discharges. If you want a battery that you run for your own benefit, perhaps alongside solar panels later, buying one is a different decision, and our guide to whether home battery storage is worth it covers that route.
You’re also tied to one supplier. Battery Boost only works on an E.ON Next electricity tariff, with a £250 exit fee in the first year. A fixed credit is only a gain if the tariff underneath it’s competitive for your usage, so compare the rate you’d pay with what other suppliers would charge you. Our rundown of E.ON tariffs explains how its fixed and smart deals differ.
And it isn’t the only way to pay less for off peak power. If your household can shift some use to cheaper hours, a time of use tariff does a similar job with no kit on the wall.
None of that makes Battery Boost a bad offer. A free battery and a monthly credit is a real thing to be handed. It just deserves the same sums as any other energy deal.
