VAT on commercial solar panels explained

VAT is one of the most misunderstood parts of a commercial solar project. The headlines about “0% VAT on solar panels” are real, but they apply to homes, not businesses. For a VAT-registered company, the VAT position is usually a cash-flow question rather than a permanent cost, and the answer changes depending on how you fund the system. This guide sets out how VAT on commercial solar actually works in 2026, where the zero rate does and does not apply, and how hire purchase, loans and leasing each handle it differently.

Is there VAT on solar panels for a business?

Yes. A commercial solar installation is a standard-rated supply at 20% VAT. The zero rate you may have read about applies only to the installation of energy-saving materials in residential accommodation under VAT Notice 708/6. It does not extend to factories, warehouses, offices, farms, schools or any other non-domestic building.

So if your installer quotes £120,000 plus VAT, the invoice is £144,000 including £24,000 of VAT. The important point for a trading business is what happens to that £24,000 next.

Reclaiming VAT on commercial solar

If your business is VAT-registered and the system is used for taxable business purposes, you can normally recover the input VAT on the equipment and installation in the usual way through your VAT return. In broad terms the £24,000 in the example above is reclaimable, so the real economic cost of the kit is the £120,000 net figure, not the gross invoice.

A few practical points sit behind that simple statement:

• The recovery is a timing matter. You pay the VAT to the supplier, then reclaim it on the next return, so there is a short period where the cash is out of the business.
• If your business makes some exempt supplies (for example certain financial, property or education activities), partial exemption rules may restrict how much VAT you can recover. Take advice if that applies to you.
• VAT is separate from the income-tax or corporation-tax relief on the asset. The capital allowances on the panels run alongside the VAT treatment and are worth understanding in their own right — our guide to capital allowances covers how solar qualifies for the Annual Investment Allowance at 100% and the 50% first-year allowance above the AIA cap.

Because the VAT is reclaimable for most businesses, it rarely changes whether a project stacks up. What it does change is when the cash leaves, and that is where the finance route matters.

How VAT differs by finance route

The VAT is the same amount whichever way you fund the system, but the point at which you pay it — and therefore the cash-flow effect — depends on the structure you choose.

Hire purchase and equipment loans

With hire purchase or an equipment loan, your business is treated as the owner and buyer of the asset from the outset. The VAT on the full purchase price is payable up front, usually at drawdown. A VAT-registered business then reclaims that VAT on its next return, so the cash is only out for a matter of weeks.

This up-front VAT is one reason many businesses choose to fund the VAT element itself, or time the install around a VAT quarter, so the reclaim follows quickly. The pay-off is ownership: under HP, a loan or a cash purchase, the business owns the system and claims the capital allowances itself, keeping the tax relief in-house.

Finance lease and operating lease

Leasing handles VAT differently. With a finance lease or an operating lease, VAT is charged on each rental rather than on the full price at the start. You pay 20% on every payment across the term and reclaim it return by return, which spreads the VAT cash-flow hit over the life of the agreement rather than concentrating it on day one.

That spreading is the main VAT attraction of leasing. The trade-off lies in the capital allowances: under a finance lease the lessor usually claims the allowances and passes the benefit back through lower rentals, unless it is a long-funding lease. Under an operating lease the lessee gets no allowances at all, but the rentals are fully deductible as a business expense. Our solar panel lease overview sets out who owns what and how the end-of-term options work.

Power purchase agreements

A PPA is a different animal again. Under a PPA the third-party funder owns the system, so the funder deals with the VAT, claims the capital allowances and keeps the Smart Export Guarantee income. You simply buy the electricity and pay VAT on those electricity bills. That removes the up-front cost but also removes the tax relief and export income from your business — the comparison is set out in full in our asset finance vs PPA guide.

Why ownership keeps more of the value

The core reason most finance directors prefer to own commercial solar through asset finance, rather than take a PPA, is that ownership keeps both the capital allowances and the Smart Export Guarantee income inside the business. The VAT is reclaimable either way, but only an owner claims the allowances on the panels and only an owner banks the export payments for power sold back to the grid. A PPA hands all of that to the funder in exchange for zero up-front capital.

That is why the VAT question, while important for cash flow, is rarely the deciding factor. The bigger numbers sit in the allowances and the export income, and those follow ownership.

A note on the 2026 FRS 102 change

From accounting periods beginning on or after 1 January 2026, the revised FRS 102 brings most leases on-balance-sheet for lessees, with exemptions for short-term and low-value leases. This does not change the VAT mechanics — VAT on rentals is still charged and reclaimed in the same way — but it does mean an operating lease that was once off-balance-sheet will now usually appear as a right-of-use asset and a lease liability. If lease accounting and balance-sheet presentation matter to your covenants, factor that in when comparing routes.

Working the numbers

VAT, capital allowances and the cost of finance all interact, so the cleanest way to compare options is to model each route net of tax. The worked figures on our cost page let you see the gross invoice, the reclaimable VAT and the after-allowances position side by side, rather than judging a project on the headline price alone.

In short

For a VAT-registered business, VAT on commercial solar is normally a reclaimable cash-flow item rather than a real cost. The 0% rate applies to homes, not commercial buildings. HP and loans front-load the VAT and then let you reclaim it quickly while keeping the allowances; leases spread the VAT across the rentals; and a PPA passes the VAT, the allowances and the export income to the funder altogether.
