UK Solar Panel Grants 2026

Solar panel grants UK — 2026 funding map

Comprehensive 2026 reference for UK solar panel grants — combined-authority programmes, devolved-nation schemes, public-sector decarbonisation, foundation grants, and the tax-allowance route that delivers more value than most direct grants. Use as screening framework before any specific application.

Realistic expectations (checked 3 November 2026): most solar panel grants in 2026 are for homes or are closed. For business and non-domestic sites the only open one we found is narrow: Scotland's CARES Community Buildings Fund pays up to 80% for non-profit community buildings with low-carbon heating. Northern Ireland's NISEP (20%, solar PV capped at £30,000) is closed for 2026/27, with the next round expected in April 2027. Everyone else funds solar with cash and the allowances, a loan or hire purchase, a lease, or a power purchase agreement with no upfront cost.

Headline

Most "solar panel grants" searches in the UK are about commercial / public-sector / charity solar — where the funding mechanism varies by organisation type. Public-sector applicants used PSDS until it closed in November 2024; they now use capital budgets, borrowing, leases or PPAs. Charities use foundation grants (£10k–£250k). Profitable private-sector businesses get more value from the 50% First Year Allowance + AIA tax route (worth 17–25% of capex) than from chasing competitive grant programmes.

UK solar panel grants by organisation type

UK funding for solar panels splits sharply by who's installing them. Different programmes target different organisations — eligibility maps to your sector, not to the technology.

Public sector — schools, NHS, councils, universities

Former main route: the Public Sector Decarbonisation Scheme (PSDS), the largest UK decarbonisation grant from 2020. PSDS closed to new applications in November 2024, and in June 2025 the government said it would fund no projects beyond those already awarded.

Loans: We could not confirm an open Salix solar loan for English public bodies.

Detail: PSDS detailed page + Schools grants strategy + NHS grants strategy.

Charities, faith groups, not-for-profits

Foundation grants: Big Lottery Climate Action Fund (£50k–£250k typical), Patagonia Environmental Grant Programme (£10k–£40k), Garfield Weston Foundation (varies), Diocesan / denominational funds for faith-group property. PSDS was a public-sector scheme.

Detail: Charities grants page with case study of Cotswolds Anglican diocese 8-parish portfolio bid.

Private-sector SMEs

Tax allowances: 50% First Year Allowance + Annual Investment Allowance — worth 17–25% of capex via tax relief. This is typically the most valuable route for profitable SMEs.

Cash grants (limited): Innovate UK Clean Energy competitions (research and demonstration projects; rates set call by call), regional combined-authority programmes (£5k–£50k typical, varies by geography).

Detail: Business solar grants + 50% FYA mechanics.

Large UK manufacturers and industrial

Tax allowances: 50% FYA + AIA, worth substantially more for high-capex projects (£500k+).

Cluster decarbonisation: Industrial Cluster programmes (Solent, Humber, Black Country, Mersey-Dee) for projects bundled with broader site decarbonisation.

Supply-chain ESG financing: Major retailer-affiliated lenders (Tesco Pathways, Sainsbury's 1.5°C engagement, M&S Plan A, Co-op Future of Food) offer preferential rates for supplier solar deployment.

Why "solar panel grants" usually means tax allowances for businesses

UK government policy supports private-sector commercial solar primarily through the tax system rather than direct grants. The Annual Investment Allowance lets profitable companies deduct the full cost of most commercial systems (up to £1 million a year) from year-one profit; the 50% first-year allowance covers special-rate spend above that.

Worked example: £200,000 commercial solar at 25% main rate

50% FYA year-one tax saving: £200k × 50% × 25% = £25,000

Special-rate pool tail PV: ~£12,000-£15,000 over 20+ years

Total tax saving: ~£37,000-£40,000 = 17.5%-20% effective discount on capex

Required application: none beyond standard corporation tax return

Verdict: typically more valuable than chasing 30%-of-£200k grants requiring 200+ hours of application work and competitive selection

Frequently asked questions

Are there UK solar panel grants in 2026?
Yes, but selectively. The UK government does not offer broad cash grants for commercial solar panels to private-sector businesses; it supports those installations primarily through the tax allowance system (the 50% First Year Allowance and Annual Investment Allowance). True cash grants are now concentrated on charity-sector projects via foundation grants like Big Lottery Climate Action Fund (the public-sector PSDS closed to new applications in November 2024).
Are there government solar panel grants for businesses?
No general government cash grant for commercial solar panels exists for private-sector UK businesses. The 50% First Year Allowance and Annual Investment Allowance act as the de-facto government support — worth typically 17–25% of capital cost as tax relief. Specific regional Innovate UK competitions and combined-authority programmes occasionally offer SME grants, but these are project-specific and competitive.
How do I apply for solar panel grants in the UK?
Application route depends on organisation type and grant programme. Public-sector applicants applied to PSDS through the Salix portal during open windows; the scheme closed to new applications in November 2024. Charities apply to relevant foundation grants individually. SMEs apply to regional combined-authority programmes (MEEF London, GMCA Manchester, WMCA Birmingham) where eligible. Tax allowances require no formal application — they are claimed in your annual corporation tax return.
How much are solar panel grants worth in the UK?
Grant values vary substantially: foundation grants £10k–£250k typical; SME regional programmes £5k–£50k. Tax allowances are worth 17–25% of capex for profitable trading companies on the standard tax rate. Many organisations end up combining multiple support routes — e.g. Capital budgets, leases, PPAs and regional funding where available.
Who is eligible for UK solar panel grants?
Different programmes have different eligibility: PSDS was for public-sector bodies and closed to new applications in November 2024. Foundation grants — registered charities and faith groups typically. Innovate UK — public + private sector with novel R&D component. Regional combined-authority — varies by programme but typically SMEs in the geography. Tax allowances — profitable trading companies subject to UK corporation tax.
Are solar panel grants available in Scotland, Wales, and Northern Ireland?
Yes, but they are narrow. Scotland: the Business Energy Scotland SME Loan is not taking solar PV applications, and the CARES Community Buildings Fund helps charities and non-profits. Wales: the Development Bank of Wales Green Business Loan Scheme, and Salix loans for public bodies. Northern Ireland: the NISEP Commercial Energy Saving Scheme (20%, solar PV capped at £30,000) is closed to new applications for 2026/27, with the next round expected in April 2027. UK-wide tax allowances apply identically in all four nations.
Can I get a solar panel grant for my home?
Domestic solar grants are different from commercial. The Boiler Upgrade Scheme covers heat pumps not solar PV. ECO4 supports low-income households with energy efficiency including solar in some cases. Smart Export Guarantee provides export tariffs. This page focuses on commercial solar grants for businesses, public-sector, and not-for-profit organisations — domestic queries should consult the Energy Saving Trust.
