Finance Lease: Solar Asset Finance

A finance lease is a way to fund commercial solar where the lender retains legal ownership of the system while your business has full use of it for the lease term and takes all the energy savings. It sits between hire purchase and an operating lease: the asset is on your balance sheet and the risks and rewards of ownership largely sit with you, but the tax treatment is different from hire purchase in a way that suits some businesses very well.

How the tax works on a finance lease

This is the key distinction. Under a finance lease the lessor is the legal owner, so the lessor normally claims the capital allowances — and reflects that benefit by pricing your rentals lower than they would otherwise be. You, the lessee, get tax relief instead through your profit and loss account: the rental payments are an allowable deduction against taxable profit.

There is an exception worth knowing. Where the agreement is a long funding lease under the Capital Allowances Act 2001, the rules flip and the lessee can claim the allowances instead of the lessor. Whether your lease falls into that category depends on its length and terms relative to the asset’s expected life. We work through this with your accountant so the relief lands in the right place — it’s exactly the kind of detail most installer finance desks gloss over. Our capital allowances guide sets out the full framework.

Spreading the VAT

One practical advantage of a finance lease over hire purchase is VAT. On hire purchase the VAT on the equipment is payable up front (then reclaimed); on a finance lease, VAT is charged on each rental across the term. For a larger system, deferring the VAT outflow rather than funding it on day one can ease cash flow considerably.

Balance-sheet treatment and the 2026 change

A finance lease has always been an on-balance-sheet arrangement for the lessee: you recognise the asset and a corresponding lease liability, depreciate the asset, and unwind the interest through the P&L. From accounting periods beginning on or after 1 January 2026, the revised FRS 102 brings almost all leases (not just finance leases) onto the balance sheet in a similar, IFRS 16-style way — so the distinction between “finance” and “operating” leases largely disappears for lessees. If your covenants are sensitive to gearing, talk to your accountant about the timing; we flag it in every proposal because most competitors haven’t updated for it.

Worked example: a 250 kW system on a finance lease

The numbers below are illustrative — they show how the cash and tax lines move on a mid-sized commercial rooftop system, not a quote. Your own rate turns on covenant strength, term and the lender. Model your real figures with our finance calculator, and see what commercial solar actually costs for the capital side.

Take a 250 kW rooftop array installed at £280,000, funded on a 7-year finance lease:

• System cost: £280,000 — roughly £1.12 per watt installed
• Term: 7 years, paid as 84 monthly rentals
• Advance rentals: 3 months up front, about £13,050
• Indicative monthly rental: about £4,350 — already net of the lessor’s retained capital allowances, which are priced into the payment
• Annual rental cost: about £52,200
• Year-one generation: roughly 235,000 kWh (around 940 kWh per kWp)
• Year-one energy benefit: about £48,000 — assuming around 70% is self-consumed, displacing grid electricity at about 28p per kWh, with the balance exported under an SEG tariff

On a pre-tax cash basis the first-year rentals sit about £4,200 above the first-year energy benefit (£48,000 of savings against £52,200 of rentals). That gap is the line most installer finance desks skip over — but it is only half the picture.

The year-one tax effect closes it. The £52,200 of rentals is an allowable deduction, so at the 25% corporation-tax main rate it takes roughly £13,050 off the tax bill. Because the electricity you no longer buy was itself a deductible cost, both the rentals and the energy benefit run through the profit and loss account, so the honest comparison is the rental after relief against the saving after tax. On that basis year one lands close to cash-neutral, and marginally positive, and it improves every year afterwards: the rentals are fixed while grid prices tend to rise. Once the seven-year term ends the system continues on a peppercorn secondary rental, so the generation is effectively free across the remainder of its 25-year-plus life. Your accountant should run these lines against your own tax position before you commit.

Finance lease vs the alternatives at a glance

Route	Ownership during term	Who claims capital allowances	Balance sheet (lessee)	VAT timing	Typical term	Best for
Finance lease	Lessor owns; you have full use	Lessor, passed back via lower rentals (the lessee, if it is a long-funding lease)	On balance sheet	Spread across each rental	3–10 years	Spreading VAT while the lender carries the allowances
Hire purchase	You — title transfers at the end	Your business: AIA 100% up to £1m, 50% first-year allowance above (special-rate)	On balance sheet	Payable up front on the equipment, then reclaimed	2–7 years	Owning the asset and claiming the allowances yourself
Operating lease	Lessor owns; short-term hire	Neither for the lessee; the rentals are simply deductible	Historically off; on from Jan 2026 under revised FRS 102	On each rental	3–7 years	The lowest monthly cost with no plan to own
PPA	Third-party funder owns and operates	Funder, which also keeps the SEG export	Usually off — a supply contract, not a lease	On the per-kWh charge	15–25 years	Zero capital outlay, paying only per unit generated

The common thread is that every route deducts against tax somewhere; the difference is where the relief lands and who holds the asset. We model all four side by side so the choice is made on numbers, not on whichever product a single installer happens to sell.

When a finance lease makes sense

A finance lease tends to suit a business that:

• wants the lender to carry the capital allowances (for example because the rentals priced-in benefit is more useful than claiming the relief directly);
• would rather spread the VAT across the term than fund it up front;
• is comfortable not holding legal title during the term; and
• still wants to keep 100% of the energy savings the system delivers.

If owning the asset and claiming the allowances yourself is the priority, hire purchase is usually the better fit. If you want the very lowest monthly cost and don’t need ownership at all, an operating lease may be cheaper still. We model all of them, and compare the lot against paying cash and against a PPA in our asset finance vs PPA guide.

When this route is NOT the right choice

A finance lease is the wrong tool if owning the asset outright and claiming the allowances yourself matters more than spreading the cost. A company with the cash to fund the system, and enough taxable profit to absorb the relief, is usually better off buying it: it claims the full 100% Annual Investment Allowance (up to £1m) on the special-rate solar expenditure in year one and keeps every pound of saving from day one, with nothing on the balance sheet as a liability. If that describes you, read buying solar outright instead — the finance lease only wins where preserving cash and spreading the VAT outweigh the value of holding the allowances yourself.

At the end of the term

When the primary term ends you typically have three options: continue using the system on a nominal “peppercorn” secondary rental, sell the asset to a third party as the lessor’s agent (often retaining the bulk of the sale proceeds), or upgrade to a newer or larger system. We set these options out in the proposal so there are no surprises years down the line.

Common questions about solar finance leases

Is a solar finance lease tax deductible?

Yes. The rental payments are an allowable deduction against your taxable profit, so they cut your corporation-tax bill across the term rather than through a one-off capital allowance, and VAT is charged on each rental instead of up front. What you do not get on a standard finance lease is the capital allowances themselves — those sit with the lessor, who prices the benefit back into a lower rental. The one exception is a long-funding lease, where the lessee claims the allowances directly; whether your agreement qualifies turns on its length against the system’s expected life, which is worth confirming with your accountant before you sign.

Can I own the solar panels at the end of a finance lease?

Not automatically — a finance lease is not a purchase agreement, so legal title does not pass to you the way it does under hire purchase. When the primary term ends you have three practical routes: keep using the system on a nominal peppercorn secondary rental (the usual choice, since the panels still have 15-plus years of life in them), sell it to a third party as the lessor’s agent and typically retain the bulk of the proceeds, or upgrade to a newer array. If taking ownership at the end is the whole point for you, hire purchase or a straight solar panel lease-to-own arrangement is the better structure.
