Solar Panel Contracts, Leases & Ownership UK: A Guide to Older Solar Agreements
Thousands of UK homes had solar panels installed under older arrangements where the homeowner did not necessarily own the solar PV system. Some involved 20 or 25-year roof leases, third-party ownership or Feed-in Tariff agreements. Years later, homeowners can face questions about who owns the panels, what happens if the original solar company has disappeared, and what an agreement means when selling or remortgaging the property.
Do You Actually Own the Solar Panels on Your Roof?
If you paid for your solar system outright, ownership will usually be straightforward. But some older UK solar installations were supplied under very different arrangements.
During the early years of the Feed-in Tariff, companies offered homeowners solar panels with little or no upfront installation cost. In many cases the company retained ownership of the installation and received the Feed-in Tariff income while the homeowner benefited from electricity generated by the panels.
The company could also have rights over the roof under a long-term agreement. These arrangements became commonly known as rent-a-roof schemes.
What Type of Solar Agreement Might I Have?
Homeowner-Owned Solar
You or a previous homeowner purchased the system and ownership transferred with the property. This is generally the simplest situation.
Rent-a-Roof Solar
A third party installed and retained ownership of the panels, often in exchange for rights over the roof and the income generated through the Feed-in Tariff.
Solar Lease
The property may be subject to a long-term agreement giving another party rights relating to the roof space and solar equipment.
Purchased Property With Solar
You may have inherited an existing solar arrangement when buying the house, particularly if the system was installed many years earlier.
Transferred Solar Ownership
The company that originally owned the panels may have sold the installation or transferred its interest to another business.
Company No Longer Trading
The original installer or scheme operator may have ceased trading even though the solar panels and contractual arrangements remain.
What Was a Rent-a-Roof Solar Scheme?
Rent-a-roof schemes became particularly associated with the earlier years of the UK's Feed-in Tariff.
Instead of the homeowner paying thousands of pounds to purchase a solar installation, a company installed solar panels on the property and retained ownership of the equipment.
The homeowner could use electricity generated by the panels, potentially reducing electricity bills, while the third-party owner generally received the associated Feed-in Tariff income.
These arrangements frequently involved long-term agreements of around 20 to 25 years.
The Feed-in Tariff subsequently closed to new applicants, but many of the agreements created during that period continue to affect properties today.
How Can I Find Out Who Owns My Solar Panels?
Start with the paperwork associated with the property and solar installation. Useful documents may include:
- the original solar installation agreement;
- a roof lease or lease of rights;
- property purchase documents;
- Land Registry title information;
- Feed-in Tariff paperwork;
- solar warranties and certificates;
- correspondence from the original solar company; and
- letters from any company that subsequently took over the installation.
If the installation is registered under the Feed-in Tariff and you still cannot identify its owner, Ofgem has a process through which a homeowner can request information about the registered ownership of solar panels located on their property.
What If the Original Solar Company Has Gone Bust?
This is where older installations can become confusing.
A solar company's failure does not automatically mean that ownership of the panels passes to the homeowner or that an existing lease disappears.
Solar installations and associated rights can be transferred or sold to another business. In some cases homeowners may not have been clearly informed when ownership changed.
Therefore, don't remove, alter or dispose of panels simply because the company named on your original paperwork no longer trades.
First establish:
- whether you actually own the installation;
- whether a lease or other agreement remains in force;
- whether ownership has transferred to another company;
- who receives any Feed-in Tariff income; and
- who is currently responsible for maintenance and repairs.
Can a Solar Lease Affect Selling Your House?
Potentially, yes.
Where a third party has rights over the roof, the arrangement can form part of the legal work involved in selling the property.
A buyer and their conveyancer will normally want to understand who owns the solar panels, the remaining length of any agreement, maintenance obligations and what rights the solar company has over the property.
A buyer using a mortgage will also need to satisfy their lender's requirements. UK mortgage lenders have specific requirements concerning leases of roof space for solar PV systems.
This does not mean a house with leased solar panels cannot be sold. It means the agreement needs to be identified and dealt with correctly rather than discovered unexpectedly halfway through a sale.
Can Solar Panel Leases Affect a Mortgage or Remortgage?
They can.
Mortgage lenders need to protect their interest in the property and may therefore examine the terms of an existing solar roof lease when considering a purchase or remortgage.
UK Finance publishes minimum requirements relating to roof-space solar leases for lenders that use its Mortgage Lenders' Handbook, although individual lenders can have additional requirements.
If an existing agreement does not satisfy a lender's requirements, further work may be needed. Depending on the circumstances, this could include clarification or variation of the agreement.
What Happens If the Roof Needs Repairing?
This can be one of the most important practical issues with a third-party solar installation.
Major roof repairs may require some or all of the panels to be temporarily removed. If you don't own those panels, you should not assume you can simply instruct a roofer to remove them.
The agreement may specify who can remove the equipment, who pays for the work and whether compensation or other costs arise while the solar installation is not generating.
Even with homeowner-owned panels, removal and refitting can add significantly to roofing work. See our solar panel maintenance and ownership cost guide for the wider costs associated with older systems.
What Should I Check in an Old Solar Agreement?
| Check | Why It Matters |
|---|---|
| Who owns the panels? | Determines whether you can alter, remove or sell the equipment. |
| How long is left on the agreement? | Some older leases were created for 20–25 years. |
| Who receives FIT income? | The payment recipient may be different from the homeowner. |
| Who maintains the system? | Establishes responsibility when equipment fails. |
| Who pays for roof access? | Important if panels must be removed for repairs. |
| Can the agreement be transferred? | Relevant when the property is sold. |
| Is there a buyout option? | Some agreements may provide a mechanism for acquiring the system or ending the arrangement. |
| What happens at the end? | The contract should explain the position when the agreed term expires. |
Can I Buy the Solar Panels From the Lease Company?
Possibly, but this depends entirely on the agreement and the current owner of the installation.
Some homeowners may be offered or may request a buyout of the remaining interest in the solar system. The price and process can vary substantially.
Before agreeing to a buyout, establish exactly what you are purchasing, including:
- ownership of the physical panels;
- the inverter and other equipment;
- rights to any remaining Feed-in Tariff income;
- existing warranties;
- maintenance responsibility; and
- what happens to any registered property rights or lease.
Where property rights or a long-term lease are involved, independent legal advice may be appropriate before paying a substantial buyout figure.
What Happens When a 20 or 25-Year Solar Agreement Ends?
Do not assume that every agreement ends in exactly the same way.
The contract should set out what happens when the term expires. Depending on the agreement, there may be provisions dealing with ownership, removal of the equipment, transfer of the system or other end-of-term arrangements.
This is becoming increasingly relevant as some of the UK's earliest rent-a-roof installations move further through their original contract terms.
If you cannot understand the end-of-term provisions, obtain appropriate advice rather than waiting until you need to sell the house or repair the roof.
Older Solar Panels May Also Need Repairs
Contract questions are not the only issue facing early solar adopters. Equipment installed many years ago may now require maintenance or replacement.
The inverter is particularly relevant because it may not last as long as the solar panels themselves.
If you own your system and the inverter is failing, see our solar inverter replacement cost UK guide.
For broader long-term expenses, see solar panel maintenance costs UK and our guide to solar panel recycling.
Inherited an Old Solar Agreement? Start With the Paperwork
If you've bought a property with solar panels, inherited a system or discovered that the original solar company no longer exists, don't start by assuming the panels are yours or that the old agreement is irrelevant.
Identify the agreement, establish who owns the installation and understand what rights remain attached to the property.
Once ownership is clear, you can make informed decisions about repairs, buyouts, roof work, selling the property or eventually replacing the system.
Solar Contracts & Ownership FAQs
How do I know if I own my solar panels?
Check the original installation paperwork, property purchase documents and any lease or Feed-in Tariff records. Where a FIT-registered installation has third-party ownership and the owner cannot be identified, Ofgem provides a process for homeowners to request ownership information.
What happens if my solar panel company has gone bust?
The panels do not automatically become yours. Ownership of the installation or associated rights may have been transferred to another company. Establish the current ownership position before altering or removing equipment.
What is a rent-a-roof solar scheme?
Under many older schemes a company installed and owned solar panels on a homeowner's roof, usually receiving the Feed-in Tariff income while the homeowner benefited from electricity generated by the panels.
How long were solar roof leases?
Many rent-a-roof arrangements used long contract periods, commonly around 20 to 25 years, although the exact term depends on the individual agreement.
Can I sell a house with leased solar panels?
A property can potentially be sold with an existing solar lease, but the buyer, conveyancer and mortgage lender may need to review the agreement and its remaining obligations.
Can leased solar panels cause mortgage problems?
Mortgage lenders may review existing solar roof leases against their lending requirements. The effect therefore depends on the particular agreement, property and lender.
Can I buy out a rent-a-roof agreement?
Some arrangements may permit a buyout or transfer, but there is no universal right or price. The original agreement and current installation owner need to be checked.
