Solar panel finance for UK businesses

How to put commercial solar panels on finance in 2026 — the options, what they cost, and how to keep the tax relief by owning the system.

In short: you can finance commercial solar from about £25,000 without paying the full cost up front. The route you choose decides whether you own the system and keep the capital allowances and export income — so it pays to compare hire purchase, lease, loan and a PPA before you sign. We model all of them from your numbers.

What "solar panel finance" actually means for a business

Solar panel finance simply spreads the cost of a system over time instead of paying for it in one capital outlay. For UK businesses there are five practical routes, and they differ in who owns the system, who claims the tax relief, and how the VAT falls:

Hire purchase — own it at the end, claim the capital allowances on the full cost from day one.
Green equipment loan — own it from day one, often unsecured against the panels.
Finance lease — the lender owns it and usually passes the allowance benefit back as lower rentals; VAT spreads across the term.
Operating lease — the lowest monthly cost; rentals are fully deductible.
Cash purchase — the benchmark: lowest lifetime cost, full allowances, no interest.

There's also refinance and sale-and-leaseback for releasing cash from a system you already own. Compare the lot in our finance options hub.

Is it worth financing solar panels?

Usually, yes — because the maths is unusual. With most assets, financing simply adds an interest cost to something that depreciates. Solar is different: the system generates a saving (and export income) every month, and that saving is typically larger than the finance repayment. So instead of a cost, you get a small net gain from month one, and once the 2–7 year term ends the electricity is effectively free for the rest of the panels' 25-year-plus life.

The "0% finance" question

You'll see "0% solar finance" advertised, mostly in the domestic market. In commercial finance a genuine 0% rate is rare — the cost of money is real, and where a headline 0% exists it's usually recovered in the price. The honest way to judge any offer is the total cost of credit: the sum of all repayments minus the amount financed. We always put that figure in writing, alongside a cash-purchase comparison, so a "0%" claim can be checked rather than taken on faith.

Keeping the tax relief

This is where the route really matters. Solar is special-rate expenditure, so it qualifies for the Annual Investment Allowance at 100% on up to £1m, and the 50% first-year allowance above that — but only the owner can claim. Finance the system through hire purchase, a loan or cash and the relief is yours; sign a PPA and the funder keeps it. For a profitable company that relief can be worth up to a quarter of the system cost, so it's rarely something to give away.

Solar panel finance FAQs

Is it worth getting solar panels on finance?

For most commercial sites, yes. Because the repayment is usually structured to sit below the energy the system saves, financed solar is cash-flow positive from month one — you replace part of a grid bill with a smaller finance payment, then own a 25-year-plus asset. The cost of credit is real, so we always model financing against paying cash and show you the difference in pounds.

Can a business get solar panels on finance?

Yes. We arrange finance from around £25,000 to multi-million-pound projects via hire purchase, finance or operating lease, equipment loans, and refinance. Approval is based on your covenant strength and, for larger projects, the cash flows of the project itself. An indicative decision usually takes 24–72 hours.

Is there 0% finance for solar panels?

Genuine 0% finance for commercial solar is rare — most B2B finance carries an interest cost, and a true 0% offer usually has the cost built into the price elsewhere. What makes financed solar effectively "free" is different: the energy saving plus the export income typically exceed the repayment, and an owned system attracts capital allowances. We show the total cost of credit in writing so you can judge any "0%" claim on its merits.

Do I keep the tax relief if I finance the panels?

It depends on the route. Under hire purchase, an equipment loan or cash purchase you are the owner, so you claim the capital allowances (AIA at 100% up to £1m, or the 50% first-year allowance above that). Under a finance lease the lessor usually claims them and prices the benefit into lower rentals; under a PPA the funder keeps them entirely.

What credit checks are involved?

For commercial finance, lenders assess your filed accounts, trading history and balance sheet rather than a personal credit score. Stronger covenants get finer rates. Younger or thinner-covenant businesses can often still be funded — sometimes via the government-backed Growth Guarantee Scheme — though pricing reflects the risk.
