Ofgem estimates that grid balancing costs add roughly £80 a year to every household bill. That figure could rise as renewable generation increases, unless something changes. New proposals for community batteries, shared storage systems connected to the local network, aim to slice that cost and more, potentially saving typical homes up to £200 annually.
The idea, as reported by IOM3, is that neighbourhood-scale batteries, housed in a single cabinet or small container, charge up when wind or solar power is abundant and cheap, then discharge during peak evening hours when electricity is expensive. The local network avoids buying from the wholesale market at its most costly point, and the savings are passed back to connected households.
How the savings stack up
Energy Saving Trust figures show a typical 3-bed semi using 3,500 kWh of electricity a year pays around £1,050 on the price cap. Of that, about 20% goes on network charges and wholesale price volatility. Community batteries directly target that 20%, they flatten the demand curve and reduce the need for expensive gas peaker plants. If a third of UK homes were served by such systems, National Grid estimates system-wide savings of £1.2bn a year, or roughly £60 per household. Industry projections from trial operators, including Western Power Distribution, suggest the household benefit could reach £200 if the battery is sized to cover peak usage for several hours.
The catch is that no one has yet built a business model that works at scale. The upfront cost for a 2 MWh community battery, enough to serve 100–150 homes, is around £400,000. Without a guaranteed revenue stream from grid services, developers are hesitant. Ofgem is consulting on a new licensing category for community energy storage, with a decision expected by mid-2026.
Who qualifies, and who doesn’t
These batteries are designed for homes that cannot install their own solar-plus-battery system: flats, terraced houses, rented properties, or homes with unsuitable roofs. A typical domestic battery installation costs £4,000–£7,000 and takes five to ten years to pay back. A community battery requires no upfront payment from the householder, they simply opt in via their energy supplier or a local energy cooperative.
But not every neighbourhood will get one. The economics work best on estates with dense housing, high evening demand, and a local substation that can handle the connection. Rural areas with long cable runs may see higher connection costs that erode the savings. The Energy Networks Association has identified 200 priority sites across England and Wales, mostly in social housing estates and new-build developments.
What it means for your EPC and future bills
Households connected to a community battery will see a reduction in their electricity unit rate, not a change in their EPC rating. EPC measures the fabric of the home, insulation, heating system, glazing, not the grid it connects to. However, the lower running cost improves the ‘heating cost’ metric on the EPC’s recommendation report, which can nudge a D-rated property closer to a C.
The government’s Net Zero Strategy includes a target of 40 GW of battery storage by 2035, up from 4 GW today. Community-scale batteries are a small slice of that, perhaps 2–3 GW, but they are the only slice that directly cuts household bills without requiring a home retrofit. For the 8 million UK households living in rented or leasehold properties with no control over their roof, this could be the cheapest route to lower energy costs.
What to do now
Ofgem’s consultation on community energy storage closes on 31 January 2026. Homeowners who want to see a battery in their area should contact their local council’s climate action team or the regional distribution network operator (DNO), the map is available on the Energy Networks Association website. For renters and flat owners, this is the single most actionable policy on the table. Write to your MP asking for the consultation to be prioritised. The deadline for submissions is tight, and the window for real savings opens only once the regulatory framework is in place.
Frequently Asked Questions
No. Community batteries are charged from the grid during cheap off-peak periods, not from individual solar panels. They work for any household connected to that local network, regardless of whether you have solar PV.
Yes. Participation is voluntary. If your area gets a community battery, you can choose not to connect your home to it. Your energy supplier would continue to charge you the standard variable tariff.
