Balance-sheet treatment of financed solar

How a financed commercial solar system lands on your balance sheet depends almost entirely on the route you choose to fund it. The same array of panels can sit on your books as an owned fixed asset, appear only as a series of rental costs in your profit and loss account, or — from 2026 — show up as a right-of-use asset with a matching lease liability. For a finance director weighing covenant headroom, gearing ratios and reported profit, this is not a footnote. It changes the picture your lenders and shareholders see.

This guide sets out how each finance structure is treated, what the revised FRS 102 brings in for accounting periods beginning on or after 1 January 2026, and why the accounting treatment and the tax treatment are two separate questions that should both inform the route you pick.

Owned assets: hire purchase, equipment loans and cash

If you buy the system outright — with cash, an equipment loan, or on hire purchase — your business is the economic owner from the outset, and the accounting follows that reality.

The solar installation is recognised as a tangible fixed asset (property, plant and equipment) at its full cost, then depreciated over its useful life, typically 20 to 25 years for commercial PV. The funding sits on the other side of the balance sheet as a liability: the outstanding loan balance, or the capital element of the remaining hire purchase instalments. As you make repayments, that liability reduces, and the interest element is charged to the profit and loss account.

The headline effects:

• Gross assets rise by the full installed cost of the system.
• Liabilities rise by the financed amount, split between current (due within twelve months) and non-current.
• Net assets are broadly unchanged at the point of purchase — you have swapped cash or a financing commitment for a productive asset of similar value.
• Gearing increases because you have added debt, which lenders watching your covenants will notice.

Because you own the asset, your business also claims the capital allowances on it. Solar PV is special-rate (integral-feature) expenditure, so it qualifies for the Annual Investment Allowance at 100% on up to £1m of qualifying spend a year, with a 50% first-year allowance available above that threshold. It does not qualify for full expensing, which is reserved for main-rate plant. We cover the mechanics in detail in our guide to capital allowances on commercial solar. Hire purchase and equipment loans both keep these allowances — and the Smart Export Guarantee income — with your business, which is the central reason ownership routes tend to beat a third-party PPA over the life of the system.

Finance leases: on balance sheet, lessor claims allowances

A finance lease transfers substantially all the risks and rewards of ownership to you, the lessee, even though legal title stays with the funder. Under existing UK GAAP this has long meant on-balance-sheet treatment.

You recognise the solar system as an asset and book a corresponding lease liability for the present value of the minimum lease payments. The asset is depreciated; each rental is split between an interest charge and a reduction of the liability. So a finance lease looks very similar to a hire purchase arrangement on the balance sheet — assets up, liabilities up, gearing up.

The tax treatment diverges, though. With a finance lease the lessor usually claims the capital allowances and passes the benefit back to you through lower rentals. Your rental payments are deductible against profits, but you are not claiming the allowances directly. That can suit a business already using its full Annual Investment Allowance elsewhere, or one without enough taxable profit to absorb the relief.

Operating leases: the historic off-balance-sheet route

An operating lease is, in substance, a rental: the funder retains the risks and rewards of ownership, and you pay to use the system for an agreed term.

Under the old rules an operating lease was the classic off-balance-sheet structure. The asset and the financing obligation never appeared on your books — you simply charged the rentals to the profit and loss account on a straight-line basis as an operating expense. This kept reported gearing lower and left covenant headroom intact, which made operating leases attractive to businesses that wanted the energy savings without the debt showing.

For tax, an operating lease lessee gets no capital allowances (the lessor owns and depreciates the asset), but the rentals are fully deductible. That is a clean, simple treatment — though it does mean the allowances and export income sit with the funder rather than with you.

What changes under FRS 102 from January 2026

The revised FRS 102, effective for accounting periods beginning on or after 1 January 2026, brings in a single on-balance-sheet lease model for lessees, closely modelled on the international standard IFRS 16.

The practical effect is that the long-standing operating-lease exemption largely disappears. For most leases you will now recognise:

• a right-of-use asset, representing your right to use the solar system over the lease term, and
• a lease liability, representing the obligation to make the future rental payments.

The right-of-use asset is depreciated, and the lease liability unwinds with an interest charge — so the profit and loss profile becomes front-loaded compared with the old straight-line rental expense. Two exemptions survive: short-term leases (twelve months or less) and leases of low-value assets. A commercial solar installation will rarely qualify for either, so most solar operating leases entered into for 2026 periods onward will come onto the balance sheet.

For finance directors this matters for three reasons. First, gearing ratios rise as previously invisible lease obligations appear as liabilities. Second, EBITDA can look stronger because rental costs are replaced by depreciation and interest, which sit below the EBITDA line. Third, and most importantly, you should check your loan covenants now — agreements written before this change may define gearing or interest cover in ways that are tripped by the new liabilities, even though nothing has changed about your underlying cash flows. Talk to your lender before the transition rather than after.

VAT and the cash-flow dimension

VAT on the equipment is reclaimable in full by a VAT-registered business, whichever route you choose. The difference is timing. With a hire purchase agreement, cash purchase or equipment loan you pay the VAT on the full system cost up front and reclaim it on your next return. With a lease, the VAT is charged on each rental and spread across the term, which softens the initial cash outlay. For a capital-constrained business that timing difference can be as relevant as the headline finance cost.

Choosing with both ledgers in mind

The right structure is the one that fits both your tax position and the balance sheet you want to present. If you are profitable and want to keep the capital allowances and export income, an ownership route — hire purchase, equipment loan or cash — usually wins, accepting that the debt shows on your books. If covenant headroom or off-balance-sheet treatment used to be the deciding factor, the 2026 FRS 102 change has narrowed that advantage considerably, and the decision now turns more squarely on tax and total cost.
