Operating Lease: Solar Asset Finance

An operating lease is the lightest-touch way to fund commercial solar. You pay a rental for the use of the system rather than to buy it, the lessor keeps ownership and the residual-value risk, and at the end of the term you can hand the equipment back, extend at a reduced rental, or — in some structures — buy it at fair market value. Because the lessor is taking the residual risk, the monthly cost is usually the lowest of any funded route.

Who it suits

Operating leases are most attractive to organisations for which owning the asset and claiming the capital allowances simply isn’t the priority — or isn’t possible. That includes:

• charities and non-taxpaying bodies that can’t use capital allowances anyway, so there’s no value lost in letting the lessor keep them;
• businesses with little current taxable profit, where the allowances would otherwise sit unused;
• organisations focused above all on the lowest possible monthly outlay and a clean, fully-deductible operating cost; and
• bodies that want to avoid residual-value and disposal risk entirely.

For a profitable company that can use the tax relief, an ownership route — hire purchase or an equipment loan — is usually better value, because the capital allowances and any export income stay with you. We’ll tell you honestly which side of that line you fall on.

The tax treatment is simple

There are no capital allowances for the lessee on an operating lease — but the rentals are a fully allowable revenue expense, deducted against taxable profit in the period they’re incurred. That simplicity is part of the appeal: no balancing charges, no disposal calculations, no capital-allowances pooling to track. VAT is charged on each rental across the term rather than up front.

The 2026 balance-sheet change matters most here

Operating leases were historically off balance sheet — one of their traditional attractions. That is changing. Under the revised FRS 102, for accounting periods beginning on or after 1 January 2026, most leases (including operating leases) must be recognised on the lessee’s balance sheet as a right-of-use asset with a corresponding lease liability, aligning UK GAAP with IFRS 16. Short-term leases (12 months or less) and leases of low-value assets remain exempt.

In practice this means you should no longer assume an operating lease will keep the system off your balance sheet. If your banking covenants are sensitive to gearing, this is an important conversation to have with your accountant now — and it’s one most solar finance pages haven’t caught up with. We flag the position in every proposal.

Keeping the savings

Whichever way the accounting falls, the energy savings are still yours: you’re using the system on your roof, so you consume the generation and cut your grid bill from day one. What you don’t get on an operating lease is ownership of the export income or the asset at the end — those stay with the lessor.

At the end of the term

You’ll typically have three choices: return the equipment to the lessor, extend the lease at a lower secondary rental, or (depending on the structure) purchase the system at its then fair market value. If long-term ownership becomes attractive partway through, we can often look at refinancing into a purchase — see refinance and sale-and-leaseback.
