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.

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 typically use PSDS (30–80% grant). 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

Primary route: Public Sector Decarbonisation Scheme (PSDS) — UK's largest decarbonisation grant programme. PSDS Phase 4 awards typically 30–80% of qualifying capital spend for bundled solar + heat pump + fabric efficiency applications. Multi-billion-pound capital across phases since 2020.

Combined with: Salix Public Sector Loans at zero interest covering the non-grant portion.

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 where charity is property-owning and meets eligibility test.

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

Private-sector SMEs

Tax allowances: 50% First Year Allowance (extended to 31 March 2026) + 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 (50–70% grant intensity for novel projects), 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 50% First Year Allowance (FYA), available until 31 March 2026, lets profitable companies deduct half the capital cost from year-one corporation tax — typically worth 12.5p per £1 of capex spent at the 25% main rate.

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


Solar panel grants for specific organisation types


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 concentrated on public-sector and not-for-profit organisations through the Public Sector Decarbonisation Scheme (PSDS), and on charity-sector projects via foundation grants like Big Lottery Climate Action Fund.
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 apply to PSDS through the Salix portal during open windows. 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: PSDS Phase 4 awards typically 30–80% of qualifying capital cost; 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. PSDS grant + Salix loan + complementary regional funding.
Who is eligible for UK solar panel grants?
Different programmes have different eligibility: PSDS — public-sector + not-for-profit (schools, NHS, councils, charities). 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 — devolved nations operate parallel programmes. Scotland: Resource Efficient Scotland, Scottish Enterprise Decarbonisation Fund. Wales: Welsh Government Energy Service, Local Energy in Wales, Cardiff Capital Region City Deal. Northern Ireland: NI public-sector decarbonisation (limited) plus specific NI Executive grants. 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.
