A solar panel lease lets you have panels installed on your roof at no upfront cost, with a company owning the panels and selling you the electricity they generate, or simply taking the export payments. It sounds appealing, but the details matter enormously. In the UK in 2026, the landscape for solar leasing and Power Purchase Agreements (PPAs) has changed significantly, and for most homeowners who can afford to buy, a properly owned system delivers substantially better financial returns. This guide explains the options honestly.
The key distinction: in a solar lease, the company owns the panels on your roof. In a solar PPA, you pay per unit of electricity generated. In both cases, the company, not you, receives the Smart Export Guarantee income and any future government incentives tied to the system. Understanding this distinction is critical before signing any agreement.

Key Takeaways
- Solar panel leases and PPAs are legal in the UK but are far less common than in the USA because UK government incentives have always favoured panel ownership.
- In a lease, you pay a fixed monthly fee; in a PPA, you pay per kWh generated at a rate below the grid price. In both cases, the installer company owns the panels.
- Leased panels typically cannot be MCS-certified under your name, so you cannot register for the Smart Export Guarantee yourself.
- Owned systems with 0% VAT currently cost £5,000–£11,000 and pay back in 7–12 years. Leases typically pay back less over the same period because savings are shared with the company.
- Leased panels complicate property sales. Buyers must agree to take over the lease, which can delay or derail sales.
- The “free solar panels” schemes widely advertised in the early 2010s were rent-a-roof leases. Most have now expired or transferred ownership back to homeowners.
Types of Solar Panel Leasing in the UK
Solar Panel Lease (Fixed Monthly Payment)
In a solar panel lease, an installer company owns the panels, installs them on your roof, and charges you a monthly fee, typically £20–£50 per month depending on system size. You benefit from the electricity generated during daylight hours, which reduces your grid consumption. The company keeps the SEG export payments and any other incentives. At the end of the lease term (typically 20–25 years), you may have the option to purchase the panels or have them removed.
Power Purchase Agreement (PPA)
A solar PPA is structurally different from a lease. The company installs panels at no charge, and instead of a fixed monthly fee, you pay for electricity generated by the panels at an agreed rate, typically 10–15p/kWh in 2026, compared to the grid rate of ~24p/kWh. You benefit from cheaper electricity for your own use; the company keeps SEG income and benefits from generating electricity at essentially zero marginal cost. Commercial PPAs are common in the UK; residential PPAs are rare.
Rent-a-Roof (Legacy Scheme)
The rent-a-roof model was prevalent in the UK from 2010–2016, when the Feed-in Tariff was paying 43.3p/kWh. Companies installed free panels on homeowners’ roofs, kept all FiT income (worth thousands per year), and gave the homeowner free electricity from the system. These schemes mostly ended when FiT rates dropped below commercially viable levels. Most homeowners who had rent-a-roof installations have had the panels transferred into their ownership, though some 25-year agreements are still active.
Lease vs Buy: The Financial Comparison
| Factor | Lease / PPA | Owned System (MCS) |
|---|---|---|
| Upfront cost | £0 | £5,000–£11,000 |
| Monthly payment | £20–£50 (lease) | None |
| SEG export payments | Goes to company | Yours (8–15p/kWh) |
| Annual bill savings | Partial | Full (£450–£700/yr) |
| Property value uplift | Negative (lease is a liability) | +1–4% |
| Panel ownership at end | Company owns unless purchased | Yours from day one |
| Complexity if selling home | High | None |
| 0% VAT benefit | Company gets it | You get it (~20% saving) |
The Property Sale Problem
This is the most significant practical issue with solar leases that is consistently underestimated at the point of signing. When you sell a property with leased panels, the new buyer must agree to take over the lease agreement. This requires conveyancing work from both parties’ solicitors, agreement from the leasing company, and the new buyer accepting a financial obligation (ongoing monthly payments) that they may not have expected or budgeted for.
In practice, leased panels can complicate sales significantly. Some buyers refuse to take on a lease and require the panels to be removed before completion. Removal costs can run to £1,000–£3,000 and the seller has no right to refuse under the lease agreement’s terms (the company may charge for early termination). Royal Institution of Chartered Surveyors (RICS) guidance notes that leased solar panels are a potential complication in property valuations and sales.
When a Lease or PPA Does Make Sense
Solar leasing makes most financial sense for:
Commercial properties and businesses that cannot access capital easily but have large energy consumption and long property ownership horizons. A 20-year commercial PPA at 10p/kWh versus grid electricity at 25p/kWh delivers genuine savings throughout the term, and commercial property sales are less sensitive to lease complications than residential sales.
Homeowners who genuinely cannot afford the upfront cost and for whom no financing option is available. In this case, a well-structured lease with a purchase option at a fair price is better than no solar at all. Check that the contract allows you to purchase the panels at a reasonable price at the end of the lease or at a defined point, and have the contract reviewed by a solicitor before signing.
Alternatives to Leasing for Those Who Cannot Afford Upfront Costs
Before committing to a lease, consider these alternatives:
The ECO4 scheme provides fully funded solar installation for households receiving qualifying benefits with EPC ratings of D or lower. This is a grant, not a loan, and you own the panels outright. The solar panel financing guide covers green mortgages, personal loans, and installer finance that allow ownership from day one with no upfront payment. Solar installer finance typically costs 5–9% APR and spreads the cost over 5–10 years, with annual savings of £500–£800 often exceeding the monthly finance payments from year one.
Case Study: Comparing Lease vs Finance on a 4kWp System
Background
A family in Coventry was considering solar but was concerned about the £7,500 upfront cost of a 4kWp owned system. They received a quote from a lease provider offering zero upfront cost for £35/month over 20 years.
Financial Analysis
The lease option cost £35 x 12 x 20 = £8,400 in total lease payments over 20 years, with the company keeping all SEG income (estimated £140/year). Their electricity bills reduced by an estimated £350/year (partial savings, as the company retained export benefits). Net benefit over 20 years: £7,000 in savings minus £8,400 in payments = net cost of £1,400.
The owned system financed via a £7,500 personal loan at 7% APR over 5 years cost £148/month. Annual savings including SEG: £650. After 5 years, loan is paid off. From year 6 onwards, £650/year is pure saving. Over 20 years: total loan payments £8,880, total savings £13,000, net benefit £4,120. After 25 years, the owned system has delivered approximately £10,000 net benefit vs the lease costing £1,400 net over 20 years with uncertain outcomes at year 21.
Decision
The family chose the financed owned system. They now own their panels outright and earn full SEG income and bill savings with no ongoing payments.
Expert Insights From Our Solar Panel Installers About Solar Leasing
“I’d estimate that one in twenty enquiries we get involves a homeowner who was offered a lease deal and wants our opinion. My honest view is that for most UK homeowners in 2026, with 0% VAT and green finance available, a lease is the least good financial option. The company offering you a free install is doing so because they’ve calculated they’ll make more from your roof over 20 years than you will. That’s not necessarily wrong, but you should understand that’s the structure. If you can borrow to buy, do that. If you can’t, call Citizens Advice about ECO4 before signing a lease,” says one of our senior solar panel installers with over 14 years of UK residential experience.
Frequently Asked Questions
Can I get solar panels for free in the UK?
Genuinely free solar panels (grant-funded, with you keeping the benefits) are available through ECO4 for qualifying low-income households. “Free” lease schemes install panels at no upfront cost but involve ongoing payments or the company keeping SEG income. These are not free; they are financial products. For a full breakdown, see our free solar panels guide.
Do solar leases affect property value in the UK?
Yes, negatively. Owned solar panels add 1–4% to UK property values. Leased solar panels are viewed as a liability by buyers and mortgage lenders, can complicate sales, and some lenders refuse to mortgage properties with solar leases that don’t include a satisfactory exit clause. RICS guidance treats leased panels as a potential complication in valuations.
Can I buy out a solar panel lease?
Most solar lease agreements include a buyout option, typically exercisable at certain points (often years 5, 10, and 15 of the agreement). The buyout price should be specified in the contract. Check the contract carefully: some agreements set a fair market value buyout price; others set fixed prices that may not reflect depreciation. Have the contract reviewed by a solicitor before signing if buyout flexibility is important to you.
Are solar PPAs available for homes in the UK?
Residential solar PPAs are rare in the UK. They are much more common in the commercial sector. Occasional residential PPA offerings appear, typically from newer fintech-backed solar companies. Read the terms carefully: the PPA rate (what you pay per kWh) should be significantly below your grid rate, and the rate should be fixed or capped for the term. Avoid PPAs with uncapped price escalator clauses.
What happens to leased solar panels when I sell my house?
The buyer must agree to take over the lease agreement. This requires work from both parties’ solicitors and agreement from the leasing company. Some buyers refuse, requiring the panels to be removed (at cost) or the lease to be terminated early (which may also involve fees). Disclosing leased solar panels to buyers and solicitors as early as possible in the sales process reduces the risk of last-minute complications.
Is solar financing better than leasing?
For most UK homeowners in 2026, yes significantly. Financing (personal loan, green mortgage, installer finance) gives you full ownership from day one, all SEG income, 0% VAT benefit, and no complication when selling. A financed owned system typically delivers £4,000–£10,000 more net benefit over 20 years than an equivalent lease. The monthly finance payment is often lower than the lease payment after accounting for bill savings.
Did rent-a-roof solar panels transfer to homeowners?
Many did. When the Feed-in Tariff rate dropped to levels that made rent-a-roof schemes uneconomical, many companies terminated their agreements and transferred panel ownership to homeowners. However, some 20–25-year agreements signed around 2010–2012 are still active until 2030–2037. If you have a rent-a-roof agreement, check the termination and buyout clauses, as the FiT scheme that made these commercially viable has now closed.
Who owns the Smart Export Guarantee income on leased panels?
The owner of the panels. In a lease, the company owns the panels and therefore registers for SEG and keeps all export payments. In an owned system, you register for SEG and keep the income. This is a significant financial difference: SEG income on a 4kWp system is typically £120–£200 per year, totalling £3,000–£5,000 over 20 years that goes to the leasing company rather than to you.
Summing Up
Solar panel leasing and PPAs are legal options in the UK, but for most homeowners in 2026, buying a system outright, with financing if needed, delivers significantly better financial returns and avoids the property sale complications that affect leased panels. The exception is commercial PPAs and genuinely low-income households for whom ECO4 is not available and financing is not accessible. If you’re considering leasing, read the contract carefully, check the buyout terms, and have it reviewed by a solicitor.
