Funding for solar panels in Scotland

Scottish businesses asking about funding for solar panels usually start from the same hope: that there is a single grant covering the cost of a commercial rooftop array. There is not, and in November 2026 the public money for business solar in Scotland is thinner than many guides suggest. The realistic plan for most companies is to fund the system themselves or through finance, claim the UK-wide capital allowances, and treat any public support as a bonus.

This guide is written from a finance perspective. It covers the borrowing (hire purchase, equipment loans, finance and operating leases) rather than the panels. This site is not a lender and not an installer; it explains how the routes work so you can compare them.

Realistic expectations: what is open in Scotland (checked 3 November 2026)

Scheme	Status	What it means for business solar
Business Energy Scotland SME Loan	Open on a rolling basis, subject to funds	Interest-free, up to £100,000 of loan over up to 8 years, but the scheme “is not accepting new applications for solar PV projects”, and there is no cashback on batteries
Scottish Industrial Energy Transformation Fund (SIETF)	Closed: the last call closed in March 2025	No current route, and it never funded solar PV
CARES Let’s Do Net Zero Community Buildings Fund	Open, first come first served	Non-profit charities and community companies only, up to £80,000 at 80%; check the current guidance on heat decarbonisation before assuming a solar-only project qualifies
Scotland Recycling Fund (Salix)	Open for 2026/27	Public bodies only: interest-free, match-funded loans
Home Energy Scotland	Homeowners only	Not for businesses or landlords, and standalone solar PV was withdrawn for new applicants in 2024

We found no current Scottish Enterprise, Highlands and Islands Enterprise or South of Scotland Enterprise capital grant for business solar, so do not budget for one. Business Energy Scotland’s free energy assessment and advice line (0808 808 2268) is still worth using, because the assessment is also the entry point to the SME Loan for the measures it does cover.

What Scotland does differently, and what it means for the numbers

Several Scottish rules change the economics of a commercial array, even though none of them is a grant.

• No business rates on the plant until 2035. Under SSI 2023/32, plant on non-domestic property that generates or stores power from wholly or mainly renewable sources, including storage batteries, is excluded from valuation from 1 April 2023 to 31 March 2035. In England a rooftop array can add to a property’s rateable value; in Scotland it does not for the life of most finance agreements.
• Renewable Energy Generation Relief. For 2026/27, community-owned projects can get 100% relief, and other generators get a sliding relief by rateable value (100% up to £145,000).
• Planning. Class 6J of the Scottish permitted-development order sets no kW cap for solar on non-domestic buildings, but panels must not protrude more than 1m, listed buildings and their curtilage are excluded, and in conservation areas the principal elevation and road-facing side elevations are off limits. Free-standing panels are limited to 12 m2 (Class 6N).
• Grid. SP Energy Networks serves the Central Belt and the south of Scotland; SSEN Distribution serves the north, including the Highlands and islands. A Transmission Impact Assessment can be needed above 200kW on the mainland and 50kW on the islands, far lower than the 5MW threshold in England and Wales, which can affect timing on larger sites.
• Yield. PVGIS models about 908 kWh per kWp a year in Edinburgh, 900 in Aberdeen, 855 in Glasgow and 813 in Inverness at the optimal tilt (805, 791, 772 and 734 on a 10-degree flat roof). That is lower than southern England, so size the finance term to Scottish generation, not a UK average.

The support that does not change at the border

Capital allowances

Solar PV is special-rate expenditure, and the capital allowances regime is the same in Scotland as in the rest of the UK. When your business owns the system it claims capital allowances: the Annual Investment Allowance gives 100% relief on up to £1m of qualifying spend per year, and above that companies can claim the 50% first-year allowance, with the balance written down at the special rate.

Solar does not qualify for 100% full expensing, which is for main-rate plant only. For most commercial arrays, comfortably inside the £1m AIA limit, the practical outcome is the same, but the legal basis is different and worth getting right with your accountant.

You only claim allowances if you own the asset. Buy with hire purchase, an equipment loan or cash and the business claims the relief. Sign a power purchase agreement and the funder owns the panels and claims the allowances. Our asset finance vs PPA comparison sets out the trade-off.

VAT

Businesses pay VAT at 20% on a commercial installation and reclaim it if VAT-registered. The 0% rate on energy-saving materials covers homes and buildings used solely for a relevant charitable purpose, not business premises, in Scotland as elsewhere.

The Smart Export Guarantee

The Smart Export Guarantee applies in Great Britain, so it covers Scotland (it does not apply in Northern Ireland). Larger suppliers must offer a tariff above zero for exports from eligible installations up to 5MW, and the payments go to the person entitled to them, normally the system’s owner. Under a PPA the funder usually keeps that income.

If a grant doesn’t fit: funding the project anyway

Because the SME Loan does not take solar PV and the larger Scottish grant funds are closed, most Scottish companies will fund the whole project themselves. The routes are:

• Hire purchase or an equipment loan. You own the system, claim the allowances and keep the export income. You pay the VAT up front and reclaim it if VAT-registered.
• A finance lease. The lessor usually claims the allowances and may reflect them in lower rentals; useful if your business cannot use the allowances itself.
• An operating lease. No allowances for you, but rentals are deductible. Under revised FRS 102, most leases come onto the lessee’s balance sheet for periods beginning on or after 1 January 2026, so the old off-balance-sheet advantage has largely gone.
• A power purchase agreement. No upfront cost, but the funder owns the system and keeps the allowances and export income.
• Paying cash. If reserves allow, compare the payback against the finance cost on the finance calculator.

How to sequence a Scottish project

1. Ask Business Energy Scotland for a free assessment, and confirm whether any measure you are planning alongside the solar (lighting, heating controls, a heat pump) is eligible for the SME Loan. The solar itself currently is not.
2. If you are a charity or community company, check the CARES Community Buildings Fund guidance, including its heat conditions, before you plan around it.
3. Confirm with your accountant that you can use the capital allowances, which tells you whether owning (hire purchase or a loan) or leasing makes more sense.
4. Size the finance term to Scottish yield, and include the rates exclusion in the saving case.

To test the finance behind a Scottish project, use the finance calculator to compare cash, hire purchase, a lease and a PPA from your own figures.
