Solar Panel Leasing for Business: How an Operating Lease Works

Rent the system, expense the cost

An operating lease is the simplest way to put solar on your roof without ever owning it. Weighing a lease against buying? Our lease vs buy solar panels comparison works through the allowances, VAT and cash for a UK company. You pay a fixed monthly rental to use the system, and the lessor keeps legal ownership from the first day to the last. When the term ends you hand the equipment back rather than owning it outright. That one fact, that the kit is never yours, shapes everything about how this route fits your business, how it is taxed and how it lands on your accounts. It suits owners who prize a clean, predictable monthly cost over ever holding the asset.

How it works

The lessor buys and owns the array, and you sign to use it for an agreed period, typically five to fifteen years, in exchange for a fixed rental. Because the payment is set at the start, your cost is easy to budget and there is no capital outlay to find. The generation and the bill saving begin immediately while the rental is spread across the term, sized so the energy saving comfortably clears the payment. At the end the standard outcome is that the equipment returns to the lessor, though some agreements let you extend at a reduced rental or arrange removal. What separates this from hire purchase is that ownership never transfers to you.

Tax and the balance-sheet question

Because the lessor owns the asset, the capital allowances accrue to them, not to you. What you get instead is that the rentals are treated as ordinary revenue expenses, fully deductible against taxable profit over the life of the lease. It helps to know what you are foregoing: an owner would claim the Annual Investment Allowance for 100 per cent first-year relief up to £1m, and solar being special-rate means full expensing never applied anyway. None of that reaches you on a lease. The old attraction was off-balance-sheet treatment, but that can no longer be assumed. Under IFRS 16, and under FRS 102 for accounting periods beginning on or after 1 January 2026, most leases sit on the lessee’s balance sheet as a right-of-use asset and a liability, so if off-sheet status is your reason for leasing, confirm the current position with your accountant first. This is general information, not advice.

What to watch, and who it suits

Read the end-of-term position carefully, including who pays to remove the system or make good the roof, and check the break costs if you might relocate or exit early. Because you never own the array, the total lifetime cost usually runs higher than owning, so compare the whole term rather than the monthly rental alone; the lowest monthly figure is rarely the cheapest route once the term is added up. A lease can still be the right call for a business that values a fixed P&L cost, expects to move premises within the term, or cannot make much use of capital allowances anyway. To weigh it honestly against owning, put both through the finance calculator and read the payback and ROI maths before you decide.

Solar panel leasing for business: three different agreements

"Solar lease" is used for three agreements that work very differently. Two lease the equipment to you; the third leases your roof to someone else (see renting your roof for solar). Knowing which one is on the table tells you who owns the panels, who can claim the capital allowances and what you are left with at the end.

This page covers the first. Hire purchase differs again, because ownership passes to you at the end, and the rooftop lease, with its Land Registry and consent questions, is covered on the zero upfront solar page.

Operating leases and the balance sheet from 2026

The old attraction of an operating lease was that it stayed off the lessee's balance sheet. For companies reporting under FRS 102, that changed with the Financial Reporting Council's Periodic Review 2024 amendments, issued on 27 March 2024 and effective for accounting periods beginning on or after 1 January 2026, with earlier adoption allowed. The rewritten Section 20 removes the distinction between operating and finance leases for lessees: a lessee now recognises a right-of-use asset and a lease liability for most leases.

• Who it applies to. The FRC says the new recognition and measurement rules apply to all entities using FRS 102, including small companies reporting under Section 1A. Micro-entities using FRS 105 are not affected: the FRC made "no equivalent change" to that standard.
• The exemptions are narrow. Only short-term leases (a term of 12 months or less, with no purchase option) and leases of low-value assets can stay off balance sheet. The FRC's examples of low-value assets are tablets and personal computers, small items of office furniture and telephones, and it says a lease cannot be kept off balance sheet by breaking the asset down into low-value components. A multi-year lease of a rooftop array is unlikely to fit either exemption.
• The profit and loss account changes shape. The rental expense is replaced by depreciation of the right-of-use asset and interest on the lease liability, and the FRC notes that the interest expense will typically be front-loaded. Gearing, interest cover and EBITDA may all change, and the FRC flags loan covenant compliance as an area that may be affected.
• Lessors are largely unaffected. The operating and finance lease distinction still applies in the lessor's accounts, so a lessor may still call the agreement an operating lease even though your accounts record a right-of-use asset.

The precise position, then: a solar operating lease will normally be on the balance sheet of an FRS 102 reporter from its first accounting period beginning on or after 1 January 2026, unless the business is a micro-entity using FRS 105. Confirm the treatment for your own accounts with your accountant before relying on it.

How a solar operating lease is taxed

Coming onto the balance sheet does not move the tax relief. HMRC's Business Leasing Manual says capital allowances generally go to the legal owner "whether the lease is a finance lease or an operating lease", so under an operating lease the lessor claims them. For panels fixed to your building, HMRC treats the lessor as owning the fixture when conditions including a joint election with you under section 177 are met, so expect an election in the paperwork. You get a deduction for the lease cost instead: HMRC treats lease rentals as revenue expenditure regardless of the accounting treatment, and where a lease is on the balance sheet the deductible amount in most cases follows the depreciation and interest in your accounts. The Finance Act 2019 rules aimed to ensure that the new accounting standards would not change a lessee's tax treatment.

When the long funding lease rules flip it

The exception is a long funding lease. Under the Capital Allowances Act 2001, a lease of plant is a funding lease if, at its inception, it meets any one of three tests: it is treated as a finance lease under accounting rules, the present value of the minimum lease payments is 80% or more of the kit's fair value, or the term is more than 65% of its remaining useful economic life. A funding lease that runs for more than seven years is a long funding lease, subject to some exclusions, and then the tax position reverses: the lessee is usually the one entitled to capital allowances, and relief is given for only part of the rentals. A lease of more than seven years whose rentals, in present-value terms, cover 80% or more of the system's value can fall into this whatever the contract calls it, so have the draft tested before you sign.

End-of-term options on a solar operating lease

An operating lease ends with the equipment still belonging to the lessor, and the panels, which the Energy Saving Trust expects to last 25 years or more, usually still generating. The lease will set out some mix of four options:

• Return. The lessor removes the system. Check who pays for removal and for making good the roof, and the condition the roof must be left in.
• Extend. You keep using the system on a secondary rental. Ask how that rental will be set before you sign.
• Buy. You purchase the panels at a price the contract fixes or at a valuation. HMRC's Business Leasing Manual lists an option to buy at a price expected to be sufficiently lower than fair value among the indicators of a finance lease, so a generous buy-out clause can change the classification and, with it, the tax.
• Transfer. If you sell or leave the building, check whether the lease can pass to the buyer or new tenant, and what ending it early costs.

Whichever applies, watch the inverter: the Energy Saving Trust expects inverters to need replacing after around 12 years, so check whether the lessor replaces it during the term and what warranty is left if you extend or buy. To weigh leasing against owning over the panels' full life, line up every funding route side by side, compare the capital allowances an owner would claim, and see how leasing fits within wider renewable energy finance.
