Who pays for a home battery in Bishop’s Stortford? For most households the honest answer is: you do. But East Herts is not a council that has ignored the question, and several schemes have touched this town’s roofs in the last few years. Some are open, some are paused and one exists mainly on paper so far. This guide sets out each one, with its status as we verified it, so you can tell what is worth pursuing before you pay for anything. For where a battery goes in a Bishop’s Stortford home and how UK Power Networks is told, see our page on battery storage in Bishop’s Stortford.
Every status below was checked against the scheme’s own pages in October 2026. Schemes change, so treat each date as a prompt to check the scheme’s page again.
What East Herts Council has committed to
East Herts made a climate declaration in 2019, committing the council to become a carbon-neutral organisation by 2030. On 26 July 2023 councillors voted unanimously to widen that motion and declare a climate emergency. The 2023 motion commits the council to reducing its own carbon footprint to an absolute minimum by 2027, with a pathway to offset what remains, and to publishing annual eco-audits that residents and businesses are invited to scrutinise. It also commits the council to advice and assistance for residents moving away from carbon-producing activities.
That is a direction of travel, not a battery grant. Most of the commitments concern the council’s own estate. The practical help for households comes through the schemes below.
Solar Together: a strong local record, now paused
East Herts ran Solar Together, the group-buying scheme, with the Hertfordshire Climate Change and Sustainability Partnership and iChoosr. In August 2023 the council reported that East Herts residents had installed 1,438 solar panels through it over the previous twelve months, a collective investment of over £1.7 million. Group-buying rounds of this kind let pre-vetted installers bid for a package; in some council areas, Windsor and Maidenhead among them, battery storage has been offered as an option alongside the panels.
The scheme now trades as Switch Together. On 15 October 2026 its East Hertfordshire page said it was not active in the area and invited residents to register interest for the next round. If a round reopens, compare its offer with an independent quote on the same specification: usable battery capacity, inverter, warranty and backup, not only the total.
Warm Homes: Local Grant: real money, narrow door
This is the one live grant route. East Herts was allocated £1,500,000 of Warm Homes: Local Grant funding, and the council says up to £30,000 of measures is available per property, covering upgrades such as insulation, energy-efficient heating and renewable energy installations. Eligibility is checked through the East Herts Home Energy Support Service.
The national rules narrow it. The home must be privately owned, by you or your landlord; it must have an EPC of D, E, F or G; and the household must usually have a gross income of £36,000 or less, or receive a means-tested benefit, or live in a qualifying low-income postcode. DESNZ’s guidance funds a battery only together with solar PV, so a battery on its own does not qualify.
The EPC test matters locally. ONS puts East Hertfordshire’s median EPC score at 71, inside band C, so a typical home here is already above the grant’s range. Homes built before 1929 have a median of just 58, so older houses are the likelier fit.
The Warm Homes Loan Scheme: rules without a named lender
The government’s Warm Homes Loan Scheme rules, published for lenders and dated September 2026, set loan caps of £15,000 for solar PV and £15,000 for an electrical storage battery. Government pays participating lenders a grant of up to 20% of the loan amount to lower the interest rate, which makes it a lower-interest loan, not an interest-free one. The rules describe an initial consumer launch phase from September 2026. We have not verified a lender offering it, so we would not build a plan around it yet.
VAT: the relief everyone gets
The one help that applies to every household is the VAT rate. HMRC’s VAT Notice 708/6 zero-rates residential battery installations until 31 March 2027, with or without panels, and the rate is 5% from 1 April 2027. It is applied on the installer’s invoice; there is nothing to claim. A home EV charger is standard-rated at 20%. Our guide to VAT on solar panels and batteries explains the detail. Privately kept plug-in vehicles across East Hertfordshire rose from 3,882 to about 5,327 in the year to June 2026, so if a charger is part of your plan, check that the quote shows it as its own line at its own rate.
One planning point the schemes do not cover
None of these schemes changes planning. Inside the Bishop’s Stortford Conservation Area, East Herts’ Article 4 direction for all properties brings renewable energy equipment on dwellings within planning control, on all elevations. A battery fitted indoors changes nothing outside; for panels, or any unit on an external wall there, the council’s view comes first.
So what is actually open?
For a typical owner-occupied house in CM23 rated band C, no grant applies, and the help on offer is the 0% VAT rate. For an older, lower-rated home whose household meets the income test, the Warm Homes: Local Grant is worth an enquiry, provided panels are part of the plan. Our solar panel payback guide shows how to judge the sums without a grant. For the roof side, see solar panels in Bishop’s Stortford, and for the county, the Hertfordshire solar panels hub.
