Search for a council-backed home battery in Esher this autumn and the first thing you are likely to meet is a closed door. On 16 October 2026 the Switch Together page for Elmbridge read “We’re not open in your area at the moment” and asked residents to register for the next launch. That pause is real, but it is not the whole picture. Elmbridge has firm climate targets, one grant scheme is live through Surrey County Council, and the national VAT relief applies to every battery fitted in a home.
This guide sets out each route, what its status was when we checked, and how it sits next to an ordinary quote. For the practical side in KT10, such as where a unit goes, the grid paperwork and what PVGIS shows for an Esher roof across the year, start with our Esher battery storage guide.
What Elmbridge has committed to
Elmbridge Borough Council declared a climate emergency in 2019. It has pledged a carbon-neutral council by 2030 and a carbon-neutral borough by 2050. Its Carbon Management and Reduction Plan 2030 was first approved in September 2020 and has been revised since, and a second version is now on the council’s website.
You can see some of that policy from Esher’s own streets. In June 2023 the council put a solar carport in the Civic Centre pay-and-display car park. In December 2022 it fitted 973 panels to the Xcel leisure complex, which it estimates will save 75 tonnes of CO2 a year, and it has also put arrays on five Centres for the Community and on Hersham Village Hall. All of that is council estate work, not money for households. A target for the whole borough, though, depends on what happens on private roofs and in private garages as well.
There is already a base to build on. DESNZ records about 2,574 solar PV installations of all sizes across Elmbridge at the end of 2025, with 21.87 MW of capacity. DESNZ notes that many 2025 installations could not yet be assigned to a local authority, so the count is likely to rise when the data is revised.
Switch Together: paused, with a battery-only option
Solar Together Surrey, now trading as Switch Together, is the group-buying scheme managed by Surrey County Council with iChoosr. Elmbridge promotes it to residents. The 2025 round took registrations from 16 June to 29 August 2025, with installations scheduled for completion by March 2026.
On 16 October 2026 the Elmbridge page gave no new round dates. It said that battery storage and EV chargers are available through the scheme, and it linked to a battery-only route for households that already have panels. If you already have panels on an Esher roof, that route is the one to watch.
Registering does not commit you to anything. When a round opens, compare its offer with an independent quote on the same specification: usable battery capacity, inverter, warranty terms, the grid application, and whether backup power is designed in. A standard grid-tied battery does not keep the lights on in a power cut unless the system is built for that, so if backup matters to you, get it written into both quotes.
The Warm Homes: Local Grant: live, but narrow
The GOV.UK list of successful councils (updated 2 July 2026) puts Elmbridge in the consortium led by Surrey, with funding of £13,914,375. Surrey County Council manages the grant for 11 boroughs and districts. Its guidance, reviewed on 8 October 2026, says:
- the grant began on 1 September 2025 and is planned to run until 31 March 2028;
- the measures include solar PV, solar thermal and battery storage;
- every route needs an EPC of D, E, F or G;
- households qualify through an eligible postcode, a means-tested benefit, or an income of £36,000 or below;
- owner occupiers are not expected to contribute to the cost;
- existing solar arrays cannot be repaired or replaced under the grant.
DESNZ’s national guidance funds a battery only alongside solar PV. The page does not say whether the scheme is open, closed or has a waiting list, so ask Surrey County Council directly before you plan around it.
The tests are about the house and the household, not the postcode’s reputation. Esher ward is 69.2% owner-occupied (34.2% outright and 35.0% with a mortgage) at the 2021 Census. Owning your home does not qualify you for the grant on its own. The EPC and the income, benefit or postcode route are what decide it.
The national pieces that apply in Esher anyway
- VAT. Since 1 February 2024, batteries installed in homes have qualified for the zero rate. The 0% rate runs until 31 March 2027 and reverts to 5% from 1 April 2027, whether the battery comes with panels or on its own. Our guide to VAT on solar panels and batteries covers the detail.
- ECO4. Ofgem says it runs until 31 December 2026. It is an energy-company obligation aimed at eligible households, not a general battery fund.
- No general grant. England has no general government grant for household solar or batteries, so treat any offer of something for nothing with care.
Setting a scheme against a quote
The Energy Saving Trust (updated 19 August 2026) puts home batteries at £1,500 to £10,000. It gives about £4,600 for a 5 kWh system, suggests a typical home system might be 10 kWh and gives a typical lifespan of about 10 to 12 years. It also says savings will not always be enough on their own to justify the cost. Size from your own evening use rather than from the size of the house, which our guide to what size home battery you need walks through.
The grid step is the same whichever route you take. Esher’s town centre is in UK Power Networks’ South Eastern Power Networks area. A system whose inverters total up to 16 A (3.68 kW) per phase is notified under G98. Anything larger needs a G99 approval before work starts, and the battery’s inverter counts towards that total.
