Battery storage grants and funding for business
No UK-wide capital grant covers a business battery in 2026. Here is the status of every scheme that comes up in the search results, and what does reduce the cost.
Each scheme below was read from its official page on 7 October 2026, and is linked. The Welsh, Scottish and Northern Irish rows and the note below were read on 3 November 2026.
Expect no grant for a business battery. We have read every scheme that comes up for one, and as of 3 November 2026 none funds a standalone battery:
- The Industrial Energy Transformation Fund has closed with no successor, and batteries were never an eligible technology under it.
- Business Energy Scotland's SME Loan pays no cashback on batteries and does not say a battery can be loan-funded.
- The Development Bank of Wales Green Business Loan names solar PV and heat pumps, not batteries.
- Wales's Ynni Cymru capital grant closed on 21 May 2026, and did not fund solar-plus-battery-only projects.
- In Northern Ireland, Power NI's NISEP-funded business grant has closed for applications for 2026/27 and listed no batteries, and Invest NI's Energy Efficiency Capital Grant is paused.
Plan the battery on tax relief, finance or your own funds, and treat any grant as a bonus to confirm in writing first.
Battery storage grants for business do not exist at UK level in October 2026. The grants that come up when you search are for households or public bodies, and the one industrial scheme, the Industrial Energy Transformation Fund, has closed with no successor planned. What funds a commercial battery is a stack: tax relief and recoverable VAT, financing commercial batteries through hire purchase, lease or loan, income from grid flexibility, and in Scotland and Wales some regional loans. This page shows the status of each, dated and sourced. The UK rules that apply to a commercial battery, from the connection to planning and tax, are in one place in our buying guide.

What is open and what has closed
If a page promises a business battery grant, find the scheme in this table first. If it is not here, ask the page for the scheme name, the administering body and the application window.
Industrial Energy Transformation Fund (IETF)
ClosedEnergy-intensive industry in England, Wales and Northern Ireland
GOV.UK says there will be no further extension of the IETF and no successor fund is planned. The last competition, Phase 3 in spring 2024, is marked closed to applications.
Public Sector Decarbonisation Scheme (PSDS)
Closed to new applicationsPublic sector bodies only
GOV.UK records Phase 4 as closed to new applications in November 2024 and lists no later phase. It was never open to private businesses.
Household schemes such as the Warm Homes: Local Grant
Not for businessesHouseholds, for improving a home
These are the grants that dominate search results for "battery storage grants". They are aimed at homes, and so is the 0% VAT relief on batteries. Neither applies to a factory, warehouse, office or farm building.
Business Energy Scotland SME Loan
Open, but batteries are not a listed measureScottish small and medium-sized businesses
Interest-free loans of £1,000 to £130,000 over 8 years for the measures on its list. The page does not list batteries among eligible measures, says cashback is not available for energy storage systems (batteries), and says the scheme is not accepting new solar PV applications. Ask Business Energy Scotland before relying on it.
CARES Let's Do Net Zero Community Buildings Fund (Scotland)
Open, non-profits onlyNon-profit Scottish charities and community companies that own or lease their building for five years or more
Up to £80,000 at 80% of eligible costs, first come first served until allocated, with final claims by 15 March 2027. Its core measures include heat pumps, heat network connection, solar PV and solar thermal; check the current guidance for which projects qualify. A battery is eligible only as an add-on to a core measure, and its cost must be lower than the core measure’s. It is not open to businesses.

Development Bank of Wales Green Business Loan Scheme
Open, batteries not mentionedBusinesses based in Wales trading for two years or more
A loan, not a grant. A Senedd written answer (WQ96151, April 2025) puts loans at £1,000 to £1.5m over up to 15 years. The page lists solar PV and heat pumps under renewables and says its list is not exhaustive. It does not mention batteries, so confirm eligibility with the Bank before you plan around it.

Ynni Cymru capital grant 2026/27 (Wales)
ClosedPublic bodies, community and third-sector groups and SMEs in Wales
Applications closed at 12pm on 21 May 2026 and no later round has been announced. Projects had to include low-carbon heat as well as renewable generation, solar PV plus battery storage on its own was ineligible, and SMEs and public bodies had to find 25% match funding. The Welsh Government lists 24 awards worth £8,262,722.90.

NISEP Commercial Energy Saving Scheme (Northern Ireland)
Closed for 2026/27Commercial and other non-domestic properties in Northern Ireland
Power NI's NISEP-funded grant for business solar PV (20%, capped at £30,000) has closed for applications for 2026/27; Power NI expects the next round to open in April 2027, subject to funding approval. The scheme is run under the Northern Ireland Sustainable Energy Programme, the applicant paid 80%, and batteries were not among its listed measures.

Invest NI Energy Efficiency Capital Grant
PausedNorthern Ireland businesses
Invest NI says it is not currently accepting enquiries or new applications while it reviews the scheme, and gives no reopening date. Its April 2024 terms included battery storage, but that is history, not a route open today.

Growth Guarantee Scheme
Open, a loan guarantee rather than a grantUK smaller businesses borrowing from accredited lenders (turnover up to £45m)
The government guarantees 70% of the lender’s outstanding balance after recovery, and the borrower stays fully liable. Term loans and asset finance run from three months to six years, with a £2m maximum per business group. It makes lending easier to obtain; it does not pay for the battery. The Bank has announced longer terms and a higher turnover limit, so check current terms with the lender.
Demand Flexibility Service (DFS)
Running, revenue not a grantBusinesses and aggregators able to change demand or generation on request
NESO reduced the minimum size from 1 MW to 0.1 MW from 9 April 2026, and participants are rewarded through their energy supplier or a third-party aggregator. From 7 October 2026 DFS can also procure constraint management actions. Income is earned for delivery and is not guaranteed.
Capacity Market
Open under its rules, revenue not a grantGeneration, storage and demand-side response, with a 1 MW minimum per unit
Regulation 15 of the Electricity Capacity Regulations 2014 sets a minimum capacity threshold of 1 MW. Smaller sites generally take part through a Capacity Provider that aggregates them; the Rules provide metering for an aggregating Capacity Provider. Payments are for being available when the system is tight, and a business battery normally takes part through an aggregator.

In Scotland, Wales and Northern Ireland
- Scotland: the Business Energy Scotland SME Loan is an interest-free loan, not a grant, and pays no cashback on batteries. For business rates, SSI 2023/32 takes plant on non-domestic property that generates, stores, transforms or transmits power from wholly or mainly renewable sources, storage batteries included, out of valuation from 1 April 2023 to 31 March 2035.
- Wales: the Development Bank of Wales Green Business Loan does not name batteries, Ynni Cymru is closed, and SI 2023/1229 excepts plant storing power from listed renewable sources from rating valuation to 31 March 2035. The Development Bank of Wales loan, the closed Ynni Cymru grant and the Welsh rates exception are set out with the South Wales network charges on our page on funding and tax for a business battery in Wales.
- Northern Ireland: Power NI's NISEP-funded grant for business solar PV (20%, capped at £30,000) has closed for applications for 2026/27; Power NI expects the next round to open in April 2027, subject to funding approval. It listed no batteries, Invest NI's Energy Efficiency Capital Grant is paused, and the Smart Export Guarantee does not apply, because it covers installations in Great Britain only.
What actually funds a business battery
Tax relief and VAT
For most businesses the biggest lever is tax rather than a grant. The Annual Investment Allowance gives a 100% deduction in year one on up to £1 million a year of qualifying plant and machinery, and a battery is plant and machinery. Above £1 million a year, a company claims the 50% first-year allowance on special-rate spend, which is how this site treats a battery, as HMRC treats solar panels; the rest is written down at 6% a year (see our tax guide). VAT on a commercial battery is 20%, and a VAT-registered business can normally reclaim it. Our guide to capital allowances on battery storage sets out the rates, the worked examples and the open question. Whether a battery counts as main-rate or special-rate plant decides the relief a company gets above the allowance, and this site takes the cautious reading.
Financing commercial batteries
Most commercial batteries are bought outright, financed, or supplied under a contract that spreads the cost. The main routes are:
- Cash purchase. Simplest, and the claimant of the allowances is clear.
- Hire purchase or a bank loan. You buy the battery and spread the payments; with hire purchase, ownership passes on the final payment. Lenders can use the Growth Guarantee Scheme for term loans and asset finance, subject to the scheme's limits above.
- Lease. You pay rentals and do not own the asset. From accounting periods beginning on or after 1 January 2026, FRS 102 brings most leases onto the lessee's balance sheet, with exemptions for short-term leases and leases of low-value assets.
- Service contract or shared savings. A provider owns and operates the battery and charges for the service. The accounting and the question of who claims the allowances depend on the contract.
Whatever the route, compare the total of the payments with the cost of buying outright, ask who claims the capital allowances, and check how the arrangement appears in your accounts. Our post on how UK businesses finance a battery goes through each route and the questions to ask.
Grid-flexibility revenue
A battery can earn from the grid as well as save on your bill. Two routes appear in the table above: the Demand Flexibility Service and the Capacity Market. Both normally work through an energy supplier or an aggregator, who agree the terms with you, and both pay for delivery. Whether a particular site can take part depends on its size, its connection and what the battery is needed for on site, which is why this page publishes no income figures. See grid services and revenue stacking for how these streams combine.
Regional and local schemes
Local authorities and combined authorities sometimes run business decarbonisation schemes. They open and close, they vary by area, and we have not verified any that currently funds a battery, so none is listed here. GOV.UK's business finance and support finder is the place to check what is live for your postcode.
If a grant doesn't fit: the routes that fund a battery
Most businesses buy a battery without a grant. These are the realistic routes for a half-hourly metered site, with one dated fact about each and the questions worth asking. This is information about how each route works, not an offer of credit: this site does not arrange finance and does not pass your details to a lender or provider.
| Route | How it works | Questions to ask |
|---|---|---|
| Asset finance, hire purchase or lease | Lenders can use the Growth Guarantee Scheme for term loans and asset finance from three months to six years, up to £2m per business group; the government guarantees 70% to the lender and the borrower stays fully liable (British Business Bank). Under FRS 102, most leases come onto the lessee's balance sheet for accounting periods beginning on or after 1 January 2026. | Who claims the capital allowances? What do the payments total against buying outright? Does the term run past the battery warranty? |
| Service contract, sometimes alongside a solar power purchase agreement (no upfront cost) | A provider owns and runs the battery and charges you for the service or the savings. Who claims the capital allowances depends on the contract. | Who owns the battery at the end? How is the charge reset if your peaks or the DUoS rates change? |
| SME or green loan | The Growth Guarantee Scheme terms above also apply to term loans. In Wales the Development Bank's Green Business Loan runs from £1,000 to £1.5m over up to 15 years (Senedd WQ96151), but its page does not name batteries. | Will the lender accept a battery as the asset? Is the rate fixed for the whole term? |
| Capital allowances | The Annual Investment Allowance gives a 100% deduction on up to £1m a year. Above that, whether a battery is main-rate or special-rate plant is not settled, and this site takes the cautious reading: how the allowances apply to a battery. | Is the company within the £1m allowance this year? Has your accountant taken a view on the classification? |
| Own funds, judged on payback | Payback is the installed cost divided by the annual benefit, and the benefit comes from your own half-hourly data. This site publishes no typical payback; it publishes what a commercial battery costs and the charge bands, and the peak shaving calculator applies them to your peak. | How many weekdays does the site really peak in the red band? Does the case survive if you halve the saving? |
Specialist finance and power purchase agreement sites explain those routes in more depth; this page does not compare lenders or providers. The form below asks how you expect to fund the battery, so the reply can start from that route.
How to check a business battery grant claim
- Name the scheme. A real grant has a name, an administering body and an official page.
- Check who it is for. Household, public-sector and business schemes are different, and many pages mix them up.
- Find the dates. A window that closed does not become open again because a page still describes it.
- Check that batteries are eligible. Some schemes fund solar PV or heat pumps and not storage.
- Look at the page's own date. Funding pages go stale quickly.
Battery storage grants and funding: common questions
Is there a government grant for commercial battery storage?
Not a UK-wide one, as of October 2026. The Industrial Energy Transformation Fund has closed with no successor planned, the Public Sector Decarbonisation Scheme closed to new applications in November 2024, and the household grants are for homes. What does reduce the cost is tax relief, VAT recovery, finance and, for some sites, grid-flexibility income.
Did the IETF pay for batteries?
No. Batteries were never an eligible IETF technology: the fund paid for industrial energy-efficiency and decarbonisation projects, and solar PV and other electricity generation were excluded too. It is now closed: GOV.UK says there will be no further extension and no successor fund is planned.
Can a business use the 0% VAT rate or a household battery grant?
No. The 0% VAT relief on installing a battery applies to residential accommodation and buildings used solely for a relevant charitable purpose, and the household grants are for homes. A commercial battery is standard-rated for VAT at 20%, which a VAT-registered business can normally recover. Our tax guide sets out the detail.
Can a battery earn money from the grid?
It can, through schemes such as the Demand Flexibility Service and the Capacity Market, usually via a supplier or an aggregator. The Demand Flexibility Service has a 0.1 MW minimum from April 2026 and the Capacity Market a 1 MW minimum per unit, which smaller sites generally meet through an aggregator. The income depends on delivery and is not guaranteed, so this page publishes no income figures.
Can I finance a battery without paying upfront?
Some suppliers offer hire purchase, leasing or service contracts that spread or remove the upfront cost, and lenders can use the Growth Guarantee Scheme for term loans and asset finance. The cost sits in the contract instead. Check how the arrangement is accounted for, who claims the capital allowances, and what the total payments are against buying outright.
