Solar panel grants and funding for business

The honest position on grants

No scheme currently hands UK businesses money towards solar as a general entitlement. When a page promises a grant and then asks for your postcode and phone number, it’s usually collecting leads for an installer rather than pointing you at funding.

That’s less bleak than it sounds. Between capital allowances, VAT recovery and the rates exemption, the effective cost of a system is meaningfully lower than the invoice, and for some businesses a sector fund or a finance structure closes the gap further. It just arrives through the tax return rather than as a cheque.

Capital allowances, where the real support sits

Solar equipment qualifies as plant and machinery, which brings it into the capital allowances regime. For the great majority of commercial installations, the Annual Investment Allowance relieves the full cost against taxable profits in the year of purchase, which is about as favourable as capital expenditure treatment gets.

One technical point matters if you’re spending heavily. Solar is treated as special rate expenditure, which puts it outside the full expensing regime available for main rate plant. In practice the Annual Investment Allowance covers typical commercial projects regardless, and businesses whose qualifying spend exceeds the annual limit fall back on first year and writing down allowances for the balance.

Allowances only have value where there are profits to relieve, and the rules change with fiscal events. This is general information rather than tax advice, and your accountant should confirm how it applies to your business before you commit.

VAT on commercial installations

Commercial solar carries VAT in the normal way. The zero rate you may have seen written about applies to residential property, not business premises, and it’s a common source of confusion when a business owner has recently had panels fitted at home.

For a VAT-registered business it’s a timing matter rather than a cost, since the VAT is recovered through the usual return and capital allowances are then claimed on the net figure. For a business that isn’t VAT registered, it’s a real addition to the project cost and belongs in the budget from the start.

The business rates exemption

Onsite generation used to carry an odd penalty, where installing your own renewable plant could increase the rateable value of your premises and therefore your rates bill. In England that was addressed with an exemption covering eligible plant and machinery used in onsite renewable energy generation and storage, running until 2035.

Rating is devolved, so businesses in Scotland, Wales and Northern Ireland should check their own position rather than assuming the English treatment applies. Your rating adviser or local authority is the right place to confirm it.

Sector and regional funds worth checking

Genuine funding does exist, though it tends to be narrow and to open and close in windows. The Industrial Energy Transformation Fund targets energy-intensive industrial sites. The Public Sector Decarbonisation Scheme covers public bodies and much of the education estate. Farming in Protected Landscapes reaches rural businesses in designated areas. Regional programmes come and go through combined authorities, Local Enterprise Partnerships and schemes such as Low Carbon Workspaces in parts of the home counties.

Government maintains a current list of funding to help your business become greener, which is the sensible starting point rather than a search engine. Because windows move, a scheme that was closed when you last looked may well be open now.

When somebody else funds the system

Asset finance spreads the cost across a term, and where the energy savings exceed the repayments the system contributes from the first month rather than after a payback period. The capital allowances position depends on the structure of the agreement, which is worth establishing before signing rather than afterwards.

The other route is an onsite power purchase agreement. A funder installs, owns and maintains the system on your roof, and you buy the electricity it generates under a long-term contract. There’s no capital outlay and the maintenance obligation sits with somebody else. In exchange you don’t own the asset, the agreement runs for a long time, and the terms deserve genuine scrutiny. Look closely at what happens if you sell the building, what the pricing does over the term, and what the arrangements are at the end.

Putting it together in the right order

Sequence matters more than people expect. Establish the tax position first, because it changes the effective cost and therefore the whole case. Check whether any live fund fits your sector or region second. Only then compare buying outright against financing, because the tax treatment differs between them and comparing before you know it produces the wrong answer.

Export income sits alongside all of this. Surplus generation earns under the Smart Export Guarantee once you’re registered, and it’s a separate piece of work from the installation itself. Worth building into the plan at the start rather than discovering afterwards.
