Solar panel lease for business UK: lease to own, cost, terms
7 min read · Updated 2026-11-10 · Leasing
A solar panel lease for a business is a rental or lease to own (usually hire purchase). Monthly payments by system size, who owns it, allowances and VAT.
Quick answer: This page is for businesses leasing commercial solar panels, not households. A business solar panel lease is either a rental, where the funder keeps the system, or “lease to own”, which is usually hire purchase. On an illustrative £100,000 system over five years at 8.5% APR the repayment is about £2,037 a month (£1,018 on £50,000, £5,091 on £250,000) and the cost of credit is about £22,193. The agreement, not the label, decides who owns the system, who claims the capital allowances and how VAT is charged.

What “lease to own” actually means
Lease to own is how solar sellers describe any arrangement where you pay over time and end up owning the system. There are three real structures behind the label, and they behave differently for tax and VAT.
| Structure | Who owns it during the term | Does title pass at the end? | Capital allowances | VAT |
|---|---|---|---|---|
| Hire purchase | The funder holds title until the final payment, but the business is treated as the owner | Yes, on the final payment | The business | On the full value at the time of supply, reclaimed by a VAT-registered business |
| Lease with an option to buy (finance lease) | The lessor | Only if you exercise the option | Normally the lessor, unless it is a long funding lease | On each rental |
| Operating lease | The lessor | No: return, extend or buy at fair value | The lessor; you deduct the rentals | On each rental |
This guide is about the first two rows, because they are what “lease to own” means in practice for a business buyer. If you are comparing hire purchase with a rental lease from scratch, the hire purchase vs lease calculator runs the numbers on your own figures.
Solar panel lease: monthly payments by system size
The table is arithmetic, not a quote. It uses the same assumptions as the worked example below: no deposit, no balloon, no fees, and an 8.5% annual rate treated as an effective APR.
| System cost | 3 years | 5 years | 7 years |
|---|---|---|---|
| £50,000 | £1,571 | £1,018 | £784 |
| £100,000 | £3,142 | £2,037 | £1,568 |
| £250,000 | £7,856 | £5,091 | £3,920 |
A rental lease is priced from the residual value the lessor expects at the end of the term, so its rentals can come out lower or higher than these hire-purchase figures. Treat the table as the order of magnitude and compare written quotes. The pricing method for a rental is in how much a solar panel lease costs, and the mechanics are in how a commercial solar lease works and finance lease vs operating lease.
Why the label matters: tax and VAT
Capital allowances. Under a genuine hire purchase the business is treated as the owner from the start and claims the allowances, whatever the final payment. Solar PV is special-rate expenditure, so the claim is through the Annual Investment Allowance, which is £1,000,000 a year, or the 50% first-year allowance above that. Solar does not qualify for full expensing, which is for main-rate plant. The detail is in capital allowances on solar panels. Under a lease with an option to buy, the lessor normally claims, and the position can change if the agreement is a long funding lease. The seven-year line and the tests are set out in long funding leases and solar allowances.
VAT. HMRC’s time-of-supply manual (VATTOS9250) treats hire purchase, credit sale and conditional sale as supplies of goods, with VAT due on the full value at the tax point. A VAT-registered business reclaims that VAT in its ordinary return, so the effect is on cash flow in the first quarter rather than on net cost. A lease is a supply of services, so VAT is charged on each rental. Where a lease ends with a final optional payment, Revenue and Customs Brief 1 (2019) can change the treatment; VAT and the balloon payment on solar hire purchase works through when.
Accounting. Under the revised FRS 102, which applies to accounting periods beginning on or after 1 January 2026, most leases come onto the lessee’s balance sheet as a right-of-use asset and a lease liability. A hire purchase asset sits on the balance sheet as owned plant with the instalments as a liability. Your accountant should confirm how a specific agreement is treated.
A worked example
The figures below are arithmetic, not a quote. They assume a £100,000 system financed with no deposit, no balloon and no fees, with the annual rate treated as an effective APR, so the monthly rate is (1 + APR)^(1/12) − 1. The method is set out in solar finance rates explained.
| Term | Monthly repayment | Total repaid | Cost of credit |
|---|---|---|---|
| 3 years | £3,142 | £113,120 | £13,120 |
| 5 years | £2,037 | £122,193 | £22,193 |
| 7 years | £1,568 | £131,703 | £31,703 |
At the end of a genuine hire purchase the business owns a system with many years of generation left, keeps the Smart Export Guarantee income as the owner, and has already claimed the allowances. Under a lease with an option, those benefits depend on whether you buy, and on what the option price is.
What to check in a lease to own agreement
Ask for these answers in writing before you sign:
- Is it hire purchase or a lease? The document title, the VAT invoices and the allowances clause should agree with each other. A “lease” that says the business claims the allowances, or a “purchase” that charges VAT on every rental, is a contradiction to resolve.
- How and when does title pass? On the last payment, on payment of a separate option fee, or only on exercising an option at a stated price. If the price is “fair market value”, find out who decides it.
- What are the payments, including any final payment? A large final payment is a balloon. It lowers the monthly cost and raises the total, and it can change the VAT treatment.
- What does early settlement cost? The settlement figure and any rebate are set by the contract. The clauses to read are in the solar lease agreement checklist.
- Who is the funder, and is it who you think? Ask for the funder’s registered name and look it up on the Financial Services Register and Companies House. Most commercial solar lending to companies is unregulated business lending, so a funder may legitimately not appear on the register; that is a reason to read the agreement closely, not a red flag in itself.
- Does a separate maintenance contract run alongside? It can end on a different date from the finance.
Getting out of a lease to own deal
If you already have an agreement and want out, the realistic routes are to settle early, buy the system out or assign the agreement. The steps and the figures to compare are in how to get out of a solar panel lease, and whether a buy-out is worth it is worked through in is it worth buying out a solar lease.

Frequently asked questions
How much does a business solar panel lease cost per month?
On an illustrative £100,000 system with no deposit, no balloon and no fees at 8.5% APR, the repayment is about £3,142 a month over three years, £2,037 over five and £1,568 over seven. A £50,000 system is half of each figure and a £250,000 system two and a half times. A rental lease is priced from the residual value the lessor expects, so its rentals can differ; get written quotes.
What does lease to own mean for commercial solar?
It is a sales label, not a legal category. In a business deal it normally describes either a hire purchase agreement, where you pay in instalments and take title when the last payment is made, or a lease with an option to buy at the end. The two are taxed and accounted for differently, so the wording of the agreement matters more than the brochure.
Is lease to own the same as hire purchase?
Often, but not always. A genuine hire purchase agreement transfers ownership to the business at the end and treats the business as the owner from the start. A lease with a purchase option leaves the lessor as owner unless and until you buy. Ask which one you are signing and have your accountant read it.
Who claims the capital allowances on a lease to own solar system?
Under a genuine hire purchase the business claims them: solar PV is special-rate expenditure, so the claim is through the Annual Investment Allowance, then the 50% first-year allowance above the limit, not full expensing. Under a lease with an option, the lessor normally claims unless the long funding lease rules treat you as the owner.
How is VAT charged on lease to own solar?
HMRC treats hire purchase as a supply of goods, with VAT due on the full value at the time of supply, which a VAT-registered business reclaims in its return. A lease is a supply of services, so VAT is charged on each rental. A final optional payment can change the treatment, which is covered in the guide to balloon payments.
Can I get out of a lease to own agreement early?
Usually by settling early, buying the system out or, in some cases, assigning the agreement. The settlement figure and any rebate are set by the contract, so read the early-termination clause before you rely on a number.
