Can a business finance solar panels?

The short answer is yes. A UK business can finance commercial solar panels, and most do rather than fund the system from cash reserves. The point of asset finance is to spread the cost of the equipment over the years it generates savings, so the system effectively pays for itself out of a lower electricity bill rather than out of working capital you would rather deploy elsewhere.

This guide explains the routes available, how big a project needs to be, who qualifies, and what the approval process actually looks like. We arrange the finance; we are not an installer, so our only interest is matching your business to the structure that leaves the most value on your balance sheet.

Can you finance solar panels for a business?

Yes, and it is the normal way commercial solar gets paid for. Across the market you can put solar panels on finance through several distinct structures, each with different consequences for ownership, tax and accounting. The right one depends on whether you want to own the system, how your business is taxed, and what you want the arrangement to do to your balance sheet.

The four main routes we broker are set out on our solar panel finance page, and each has its own deep-dive under our finance products. In summary:

• Hire purchase — you pay in instalments and own the system outright at the end.
• Equipment loan — you borrow to buy the system, so you own it from day one. Often available unsecured.
• Finance lease — the funder owns the asset and you pay rentals to use it, with the rentals deductible against profit.
• Operating lease — a true rental with no obligation to own at the end.

There is also sale-and-leaseback if you already own a system and want to release the capital back out of it.

Ownership decides who keeps the tax relief

This is the part that most determines which route is right for you, so it is worth getting straight before you compare monthly costs.

Commercial solar is treated as special-rate (integral-feature) plant for capital allowances. That means it qualifies for the Annual Investment Allowance (AIA) at 100% on up to £1m of expenditure a year, and the 50% first-year allowance on spend above that. Both are permanent. Solar does not qualify for 100% full expensing — that relief is for main-rate plant only, and getting this wrong is one of the most common mistakes we see. Our capital allowances page sets out a worked example.

Who actually claims that relief depends entirely on who owns the asset:

• With hire purchase, an equipment loan or a cash purchase, the business owns the system and claims the allowances itself.
• With a finance lease, the lessor usually claims the allowances and passes the benefit back to you through lower rentals (unless it is a long-funding lease).
• With an operating lease, you get no allowances as the lessee, but the rentals are deductible as a normal trading expense.

This is the central reason ownership routes appeal to profitable, tax-paying businesses: financing via hire purchase or an equipment loan keeps both the capital allowances and the Smart Export Guarantee (SEG) income with you. That is the key difference from a power purchase agreement, where a third party owns the system, claims the allowances and keeps the export income — you only buy the power. A PPA is genuinely useful for businesses that pay little or no tax, or that cannot put up any capital, but for most trading companies owning the asset captures more value over the system’s life.

How big does the project need to be?

Most commercial solar finance starts at around £25,000 of equipment cost. Below that, the arrangement fees and underwriting time make a dedicated facility less efficient, though smaller projects can sometimes be folded into a broader equipment loan covering solar, battery storage and EV charging together.

There is no real upper limit. Rooftop and ground-mount projects running into seven figures are routinely financed; above the £1m AIA threshold the 50% first-year allowance simply applies to the balance. The larger the project, the more the choice of structure matters to the total cost over the system’s life.

Who qualifies, and how approval works

Commercial solar finance is covenant-based. Lenders underwrite the business, not the panels and not the director’s personal credit score in the way a consumer loan would. They look at your filed and management accounts, trading history, profitability and existing borrowing to judge whether the business can comfortably service the repayments.

Most established, trading limited companies qualify without difficulty. Younger businesses or those with a thinner covenant still have routes — unsecured equipment loans and the government-backed Growth Guarantee Scheme can bridge the gap — though pricing will reflect the additional risk. The honest position is that a strong covenant gets the keenest rates and the fastest decision.

The process is straightforward:

1. Model the system. Confirm the installed cost, the expected generation and the bill saving, so the repayment can be set against a real number.
2. Choose the structure. Match the route to your tax position and balance-sheet preference — that is where most of our advice goes.
3. Submit for approval. With accounts in hand, an indicative decision typically comes back within 24 to 72 hours. As a whole-of-market broker we place the deal with the lender offering the best terms for your profile rather than a single funder’s book.
4. Drawdown on commissioning. Funds are released when the system is signed off, so you are not paying for an asset that is not yet generating.

Accounting and VAT, briefly

If your business is VAT-registered, the VAT on the equipment is reclaimable. With hire purchase or a loan you pay that VAT up front and recover it; with a lease it is spread across the rentals. Either way it is not a permanent cost to a VAT-registered business.

One change worth flagging to your finance director: the revised FRS 102 brings most leases on-balance-sheet for lessees for accounting periods beginning on or after 1 January 2026, with short-term and low-value leases exempt. In practice this narrows the old accounting gap between leasing and owning, so the decision now rests more squarely on tax treatment, ownership and total cost than on keeping the asset off the balance sheet.

Getting started

For most trading businesses the question is not whether solar can be financed — it can — but which structure keeps the most value with you. If you are a tax-paying company that wants to own the asset, a hire purchase or equipment loan usually wins; if capital is the constraint, a lease or PPA may suit better. The figures decide it.
