Selling a London Property with Solar Panels

Selling a property with solar panels can raise questions that do not always arise with a standard house sale. Buyers may want to know who owns the panels, whether the system comes with the property and whether any electricity payments or agreements will transfer.

If you are selling a home in London with solar panels, preparing these details early can help you answer buyer questions and keep the sale organised.

This guide explains what to check before marketing your property, which documents to gather and how to prepare for your estate agent valuation.

Do Solar Panels Affect Selling a Property?

Solar panels can be an attractive feature for buyers because they may help reduce electricity bills. However, their appeal depends on the system, its condition, ownership arrangements and the buyer’s expectations.

Some buyers may value the potential energy savings. Others may have questions about maintenance, warranties or agreements attached to the roof.

Therefore, avoid assuming that solar panels will automatically increase your property’s selling price.

Instead, gather accurate information about the installation and ask a local estate agent how buyers in your area may view the feature.

1. Confirm Who Owns the Solar Panels

Before selling a property with solar panels, establish who owns the installation.

There are several possible arrangements.

Solar panels purchased outright

If you purchased the panels outright, you will generally own the installation. You should still gather the relevant paperwork and confirm the position with your solicitor.

Solar panels installed under a roof lease

Some homeowners agreed to let a company use their roof in return for a solar panel installation. Under this arrangement, the company may own the panels and operate under a separate agreement.

The agreement could affect the sale, so your solicitor should review its terms.

Solar panels under a finance agreement

If you financed the installation, check whether any balance remains outstanding and whether the agreement contains conditions that affect a sale.

Do not assume that every installation follows the same rules. The ownership documents will help establish what happens next.

For further guidance, read the Energy Saving Trust’s advice on buying a house with solar panels.

2. Gather the Solar Panel Documents

Buyers and solicitors may request information about the installation during the conveyancing process.

Preparing the available paperwork before marketing can help you respond more quickly.

Depending on your installation, useful documents may include:

The original installation contract.
Warranty and maintenance information.
Installation certificates and technical documents.
Details of the installer and system manufacturer.
Any roof lease or finance agreement.
Information about battery storage, if fitted.
Relevant electricity export or tariff agreements.
Instructions for monitoring and operating the system.

You may not have every document. However, gathering what you can will give your solicitor a clearer picture of the installation.

If you cannot find an important document, contact the installer, energy supplier or relevant scheme administrator for advice.

3. Check Whether the Solar Panels Have a Separate Agreement

A roof lease or third-party ownership arrangement can create additional questions during a property sale.

For example, the buyer may need to understand the agreement’s remaining term, responsibilities for maintenance and any conditions that apply when ownership changes.

Your solicitor should review the actual contract and explain the implications for the sale.

Do not promise a buyer that the panels will transfer without any additional requirements until you have checked the paperwork.

If a third party owns the installation, contact that company early to establish what information and steps are needed.

This preparation can help prevent unexpected questions later in the transaction.

4. Explain Any Feed-in Tariff or Export Payments

Some solar panel owners receive payments under an existing Feed-in Tariff (FIT) arrangement. Other installations may use a Smart Export Guarantee (SEG) tariff, which pays eligible generators for electricity exported to the grid.

These arrangements do not all work in the same way.

If your property has an existing tariff, find the relevant contract and recent statements. Check which scheme applies and ask the provider how a change of ownership should be handled.

For FIT installations, Ofgem provides guidance on registration and ownership changes. You can read its Feed-in Tariffs guidance for generators.

Avoid promising buyers a specific payment amount. Payments and eligibility depend on the installation and the applicable agreement.

Instead, provide the available records so buyers and their solicitors can assess the position.

5. Check Your Energy Performance Certificate

An Energy Performance Certificate (EPC) gives information about a property’s energy efficiency and typical energy costs.

Solar panels may form part of the property’s energy features, but their presence does not remove the need to check the EPC requirements.

Before marketing your home, check whether you already have a valid certificate. In England, an EPC is generally valid for 10 years, and sellers usually need one before marketing a property for sale.

You can check an existing certificate through the official GOV.UK Find an Energy Certificate service.

6. Arrange a Realistic Estate Agent Valuation

Once you have gathered the main details, arrange a valuation with estate agents who understand your local London market.

Tell the agent about the solar installation before the appointment. Explain whether you own the panels outright, have a lease agreement or use a separate finance arrangement.

Also share information about battery storage, warranties and any documented energy payments.

The agent can then consider these details alongside the property’s location, size, condition and comparable sales.

It is worth comparing more than one valuation. Ask each agent to explain how they arrived at their suggested asking price and whether they believe the solar installation is likely to influence buyer interest.

7. Prepare the Property for Photography and Viewings

Solar panels are often visible from outside, but buyers may also want to understand how the system works and where its equipment sits.

Before arranging photographs or viewings, consider the following:

Make the property’s main rooms clean and presentable.
Ensure the inverter or battery area is accessible where appropriate.
Gather the system manuals and available installation documents.
Prepare a clear explanation of the system’s ownership.
Provide accurate information about maintenance and warranties.
Avoid making unsupported claims about energy savings.

Do not climb onto the roof or attempt electrical checks yourself. If the installation needs an inspection, use a suitably qualified professional.

Professional photographs and an accurate floor plan can also help buyers understand the property before booking a viewing.

8. Be Ready to Answer Buyer Questions

Buyers may ask questions about the installation before deciding whether to make an offer.

Common questions include:

Who owns the solar panels?
When were they installed?
Is there a remaining finance balance?
Does the property have a roof lease?
Is battery storage included?
Are warranties still valid?
Does the system receive export payments?
What documents will be provided at completion?

You do not need to know every technical detail yourself. Your estate agent can communicate the available information, while your solicitor can handle legal questions about ownership and contracts.

Clear answers can help buyers understand what they are purchasing and reduce confusion during negotiations.

9. Consider Offers in the Context of the Whole Sale

When an offer arrives, consider more than the headline price.

A buyer’s position, financial arrangements, timescale and understanding of the solar installation may all matter.

For example, a buyer may request additional information about a roof lease or finance agreement before proceeding. Responding promptly can help keep the transaction moving.

Discuss the offer with your estate agent and seek legal advice where necessary.

Frequently Asked Questions

Do solar panels increase a property’s value?

They may appeal to some buyers, but there is no guaranteed increase in value. The system’s condition, ownership, energy performance and local market demand can all influence how buyers view the property.

Can I sell a house if the solar panels are leased?

A sale may still be possible, but the lease terms can affect the process. Ask your solicitor to review the agreement and explain any requirements before proceeding.

Do I need to transfer my solar panel payments to the buyer?

The answer depends on the scheme and the contract. Contact the relevant provider or scheme administrator and follow the required ownership-change process.

Should I repair solar panels before selling?

If you suspect a fault, seek advice from a qualified solar panel professional. Obtain a clear assessment before deciding whether repairs are worthwhile. Keep any inspection or repair records for potential buyers.

Do I need an EPC if my property has solar panels?

Solar panels do not automatically remove the usual EPC requirements. Check whether your property has a valid certificate before marketing it.

Final Thoughts

Selling a property with solar panels in London does not have to be complicated. The key is to establish who owns the installation, understand any agreements and gather the available documents before buyers start asking questions.

Check your EPC, tell your estate agent about the system and seek legal advice if the panels are leased or financed.

With the right preparation, you can give buyers clearer information and help your solicitor address important questions during the sale.
