How to get out of a solar panel lease (UK)

Exiting a solar panel lease in the UK: buy-out, secondary rental and assignment for commercial leases, and how they differ from domestic rent-a-roof deals.

If you are trying to get out of a solar panel lease, the first thing to establish is what kind of lease you actually have. The phrase covers two very different arrangements, and the exit routes for one have almost nothing in common with the other. A commercial solar lease is a finance agreement on equipment your business uses; a domestic “rent-a-roof” deal is a long lease of part of your roof to a third party. This guide deals mainly with the commercial position, because that is where finance directors and owner-managers have real, contractual exit options.

First, work out which lease you are in

Most of the frustration around leased solar comes from confusing the two structures.

A commercial solar lease is arranged by a business to fund a system on its own premises. The funder owns the panels; the business pays rentals and keeps the electricity savings and, where it qualifies, the export income. These agreements run for a fixed term, usually five to ten years, and they contain settlement and end-of-term provisions you can act on.

A domestic rent-a-roof lease is the arrangement many homeowners signed in the feed-in tariff era. A solar company installed panels for free in exchange for a 20- or 25-year lease over the roof space and the right to the generation income. The homeowner kept only the free daytime electricity. These are genuinely hard to exit and the main pain points are mortgage and house-sale related, not finance settlement.

If you are a business and you signed a lease to fund your own kit, you are almost certainly in the first category. The rest of this guide assumes that. Our solar panel lease page sets out how these commercial agreements are structured in the first place.

The three ways out of a commercial solar lease

There are three realistic exit routes. Which is available depends on whether you have a finance lease or an operating lease, and on what your agreement says.

1. Settle and terminate early

Most finance leases allow early settlement. You pay the outstanding rentals, usually discounted to present value, plus any documented fees. Because the funder owns the asset on a finance lease, early settlement does not automatically transfer ownership to you. Read the clause carefully: some agreements end the contract on settlement but leave the funder owning the panels, with a separate nominal purchase needed to take title.

Settlement makes most sense when you are selling the site, refinancing the wider business, or have surplus cash and want to stop paying a rental margin you no longer need.

2. Buy out the system

A buy-out converts you from renter to owner. You pay the agreed buy-out figure, take title to the panels, and from that point the system is your asset. This is often the smartest exit because, going forward, you keep the Smart Export Guarantee income and you may be able to claim capital allowances on the purchase. Whether it is worth it turns on the buy-out price versus the rentals you would otherwise keep paying, so it pays to run the figures before you commit. If you want to fund the buy-out rather than use cash, a hire purchase agreement can spread it while still giving you ownership and the allowances at the end.

3. Assign or novate the lease

If you are selling the premises or the business, you may be able to assign the lease to the buyer or novate it so they take over the rentals. This needs the funder’s consent and the incoming party’s covenant has to pass their checks, but it is common on commercial property sales where the new occupier wants the existing solar. It is usually cleaner than settling and re-leasing, because the system stays in place and the agreement simply transfers.

What it actually costs to leave

Do not assume early exit is cheap. The funder priced the deal expecting to earn rentals across the full term, so a settlement figure reflects the remaining rentals, typically discounted, sometimes with an early-termination fee. On an operating lease the position can be tighter still, because the funder retained the residual value risk and built that into the rentals.

Before you commit, get the exact figure in writing and compare three numbers: the cost to exit now, the total of the rentals you have left, and what you would gain by owning the system outright. Our finance calculator helps you put pounds against each, so you can sense-check the settlement quote and see how owning compares with continuing to rent.

The 2026 accounting change worth knowing

From accounting periods beginning on or after 1 January 2026, revised FRS 102 brings most leases onto the lessee’s balance sheet as a right-of-use asset and a corresponding liability, with short-term and low-value leases exempt. If you are exiting an operating lease partly because it sat off balance sheet, that advantage largely disappears under the new rules. For some businesses this tips the decision toward buying out and owning the asset cleanly, rather than re-leasing.

Why ownership is usually the better destination

The reason buy-out and settlement keep coming up as sensible exits is that ownership puts the economics back in your hands. When the business owns commercial solar, it claims the capital allowances. Solar PV is special-rate (integral-feature) expenditure, so it qualifies for the Annual Investment Allowance at 100% on up to £1m a year, with a 50% first-year allowance on spend above that. It does not qualify for 100% full expensing, which is restricted to main-rate plant, but both the AIA and the 50% allowance are permanent. The owner also keeps the Smart Export Guarantee income from exported power.

Under a lease the funder retains the asset, and under a PPA a third party keeps both the allowances and the export income while you simply buy the electricity. That is the core reason businesses move from rented or third-party-owned solar toward owning it: the allowances and the export income stay with you.

The domestic rent-a-roof exception

If you are a homeowner trying to get out of a 25-year roof lease, the routes above do not apply. Your options are narrower: negotiate a buy-out of the lease from the operator (often several thousand pounds), have the panels removed at your cost, or work around the lease when remortgaging or selling by getting the lender to accept the lease terms. These are property and mortgage problems rather than asset-finance ones, and they are outside what we arrange. We finance business-owned solar, not domestic rent-a-roof reversals, so a specialist conveyancer is the right first call there.

Getting the exit right

The single biggest mistake is acting on the wrong assumption about which lease you hold and what it permits. Read the settlement, buy-out and assignment clauses, get the exact figures in writing, and model owning the system against continuing to rent it. For most commercial agreements, a buy-out funded sensibly leaves you owning an appreciating-utility asset with the tax relief and export income attached.

If you want a second view on your numbers, request a quote and we will model the settlement, buy-out and refinance options side by side so you can see which exit leaves your business better off.
