Ofgem’s latest data shows that households on standard variable tariffs pay roughly 24.5p per kWh for electricity, but the wholesale cost fluctuates from below 5p at night to over 35p on winter evenings. That gap is the problem community batteries are built to fix.
The UK government published a consultation on 28 March 2025 proposing a new regulatory framework for neighbourhood-scale batteries, assets typically between 1 MW and 10 MW that sit on the local distribution network, not behind a single meter. As reported by GOV.UK, the aim is to let these batteries buy electricity when it is cheap (or when local solar farms are overproducing) and sell it back when prices spike, with the savings passed to households in the same distribution area.
Who qualifies, and who doesn’t
The proposal targets households connected to the same low-voltage feeder as the battery, roughly 200–500 homes per installation. Eligibility is not based on income or home ownership. Renters and flats are included, provided their building sits on the same substation circuit. The Department for Energy Security and Net Zero estimates that if the policy rolls out to 100 batteries by 2030, about 40,000 homes could see savings of £30–£50 a year on their electricity bill.
That figure assumes a typical 3-bed semi using 2,900 kWh annually. Larger homes with electric heating or heat pumps would benefit more, possibly £70–£100, because their consumption pattern aligns better with peak-price periods. But the savings are not guaranteed: they depend on how the local network operator structures the tariff and whether the battery cycles frequently enough.
What it means for solar panel owners
For the 1.5 million UK homes with solar PV, community batteries offer a second income stream beyond the Smart Export Guarantee (SEG). Currently, most households export surplus solar at a fixed rate, typically 5p–15p per kWh. A community battery could buy that solar power at a higher price during the middle of the day when grid demand is low, then sell it back to the grid at peak evening rates. The difference could add 2p–4p per exported kWh, according to modelling by the Energy Systems Catapult.
That may not sound transformative, but for a home with a 4 kW system exporting 2,500 kWh a year, an extra 3p per kWh means £75 more income annually, enough to shave a year off the typical 7–9 year solar payback period. The catch is that the battery operator, not the household, captures the largest share of the arbitrage profit. Consumer groups such as Citizens Advice are pushing for a guarantee that at least 60% of the trading margin flows back to households.
Who pays for the battery, and the grid upgrades
The government proposes that community batteries be funded by commercial developers, typically energy storage companies or local energy co-ops, who recover their investment through the spread between buying and selling prices. Households would not pay upfront. But the distribution network operator (DNO) may need to upgrade local transformers and cables to handle the battery’s charge and discharge cycles. Those costs, under current rules, are socialised across all customers in the DNO region, adding roughly £2–£5 a year to everyone’s bill, regardless of whether they benefit from the battery.
The Energy Saving Trust has warned that without a clear cost-recovery mechanism, community batteries could become a “regressive subsidy”, wealthier solar owners gain, while low-income households on prepayment meters see a tiny bill increase for no direct benefit. The consultation asks for views on whether DNO upgrade costs should be charged only to battery developers or spread across the whole customer base.
What to do now
The consultation closes on 20 June 2025. Homeowners who want community storage in their area should submit a response via the DESNZ consultation portal, even a short email supporting the principle of local storage and fair cost allocation carries weight. Solar owners should ask their installer or DNO whether any pilot projects are planned in their region. The first operational community batteries could appear by late 2026, but only if the regulatory framework is finalised this year.
Frequently Asked Questions
Yes. The battery buys cheap off-peak electricity and sells it at peak times. The savings are passed to all households on the same local feeder, not just solar owners. Typical savings are £30–£50 a year for a standard 3-bed semi.
No. Community batteries sit on the distribution network, not on your property. Your electricity meter stays the same. Your supplier will apply the savings automatically through a revised tariff or a direct credit.
