If you own your solar panels outright and have the paperwork, they rarely slow down selling your house, and research links them to higher sale prices. The research ranges from a 1.6% premium for a better EPC rating to a 6.1% to 7.1% premium for homes with panels. The problems come from missing documents and, above all, from panels on a leased roof, because the buyer's mortgage lender has to approve that lease. This guide covers what the forms ask, what lenders want and how to get your pack ready before you list.
- 6.1% to 7.1% price premium linked to solar panels in a study of about 1.5 million UK listings
- 1.6% premium Nationwide found for EPC A or B homes against D-rated ones
- Feed-in Tariff rate and remaining term pass to the buyer
- Leased roofs need lender approval under the UK Finance Lenders Handbook
First question: do you own the panels?
Everything else follows from how the panels were paid for. Your conveyancer will ask, and so will the buyer's lender.
| Arrangement | Who owns the panels | What the buyer's side will want | Risk to the sale |
|---|---|---|---|
| Bought outright | You, and then the buyer | MCS certificate, electrical certificates, warranties, Feed-in Tariff or export paperwork | Low |
| Bought with a loan or finance | You, but the finance may need clearing | As above, plus a redemption statement or proof the finance is settled or transferable | Low to moderate |
| Leased roof ("free solar") | A solar company, under a long lease of your roof space | The lease, and confirmation it meets the lender's minimum requirements | Moderate to high |
Most panels fitted in recent years, including every system we install, are owned by the homeowner from day one. Leased roofs mainly date from the free solar schemes of the Feed-in Tariff years.
What the TA6 form asks
In England and Wales, sellers fill in the Law Society's TA6 Property Information Form. It includes a section on solar panels: whether the property has them, when they were installed, whether you own them outright or a lease of the roof or air space has been granted, and it asks you to supply the related documents. The 6th edition was released in October 2025 and the older 4th and 5th editions were withdrawn on 30 March 2026, so expect your conveyancer to use the current form.
Also tell your conveyancer, on the TA10 Fittings and Contents Form, whether a home battery or EV charger stays with the house. Buyers usually assume they do; say so in writing to avoid an argument on completion day.
Your solar paperwork pack
Gather these before you instruct an estate agent. A buyer's solicitor will ask for most of them, and having them ready saves weeks of back and forth.
- MCS certificate. Proves the system was designed and installed to the Microgeneration Certification Scheme standard. The buyer needs it to sign up for export payments. See MCS certification explained.
- Electrical installation certificate and Building Regulations compliance certificate. Solar is notifiable electrical work. The compliance certificate comes through the installer's competent person scheme.
- Network operator notification. The G98 or G99 confirmation that your system was registered with the local distribution network operator.
- Warranties. Panels, inverter and battery manufacturer warranties, plus the installer's workmanship warranty and the insurance that backs it. Check whether they transfer to a new owner; most do, but some need registering. Our warranties page shows how ours transfer.
- Feed-in Tariff or export paperwork. Your latest FIT statement or Smart Export Guarantee contract details.
- Planning permission, only if it was needed. Most roof panels in England are permitted development, but listed buildings and some conservation area homes need consent. See planning permission for solar panels.
- Finance or lease documents, if either applies.
- Generation records. A year of monitoring data from your inverter app is the most persuasive thing you can show a buyer who is unsure what the panels are worth.
Lost something? Ask your installer first. If they have stopped trading, MCS can issue a copy of the certificate to the current owner with proof of address and an admin fee. The competent person scheme the installer belonged to can often help with the electrical certificate.
If your panels are on a leased roof
Most mortgage conditions require the lender's consent to any lease, including a lease of roof space for panels. Lenders that use the UK Finance Mortgage Lenders Handbook for England and Wales set out their requirements at clause 5.20, and UK Finance and the Building Societies Association publish minimum requirements with a template letter for lease providers. Common conditions include:
- The lender can end the lease if it repossesses the property.
- The cost of removing the panels and making good any damage falls on the solar provider, not the homeowner.
- The buildings insurer has been told about the panels and all consents were obtained.
Some lenders will not lend on a house with leased panels at all, while they will lend where the owner bought the panels. If your lease falls short, you have three routes: ask the provider to vary the lease to meet the minimum requirements, buy the provider out, or have the panels removed. Start this before you list, because provider responses can take weeks.
Feed-in Tariff and export payments
Feed-in Tariff: the current rate and the remaining years of the contract transfer to the new owner. On completion day, read your generation meter and send it to your FIT supplier with the completion date and the buyer's name, confirming the panels were included in the sale. The buyer then applies for a change of ownership, with photo ID, their own meter reading and proof of purchase such as a solicitor's letter on headed paper, the sale agreement naming both parties, or Land Registry documents with a signed TA10.
Smart Export Guarantee: an export contract is between you and your energy supplier, so it ends when you move out. The buyer signs up with the supplier of their choice, which is where the MCS certificate matters. Our Smart Export Guarantee guide explains the rates.
What the panels are worth to a buyer
Two credible pieces of research point in the same direction but differ in size.
- Researchers at Swansea University and the University of Birmingham, using Zoopla data on about 1.5 million UK listings and published in Energy Economics, found homes with solar panels were associated with a 6.1% to 7.1% higher price, about £14,062 to £16,368. They are clear this is a correlation, not proof that panels cause the uplift.
- Nationwide found owner-occupied homes rated EPC A or B sold for 1.6% more than comparable D-rated homes, about £4,500 on an average house in England. Solar is one of the most direct ways to raise an EPC score.
Buyers also look at running costs. An EPC is required when you market your home, and if yours predates the panels, a fresh one may show a better rating and lower estimated bills.
Worked example: should you install before you sell?
Suppose you are in Leeds, where a south-facing roof produces about 946kWh per kWp a year, and you fit our 4.4kW system from £6,495.
- Yearly generation: 4.4 x 946 = about 4,162kWh.
- Assume you use 40% of it yourself: 1,665kWh x 26.32p (the October to December 2026 price cap rate) = about £438 saved.
- Export the other 60%: 2,497kWh x 12p on Outgoing Octopus = about £300 earned.
- Total benefit: roughly £738 a year.
If you stay three years you bank about £2,214 in bills and export, and the house may sell for more. If you are selling within months, the numbers depend almost entirely on the price premium, which is uncertain. Our honest view: install because you will live with the savings for a few years, not as a last-minute sale tactic. Our solar panel payback period guide goes deeper.
If you are buying a house with panels
- Ask for the paperwork pack above, and check the MCS certificate matches the address and system size.
- Confirm with your lender early if the panels are leased.
- Ask for generation data and check it against the MCS estimate.
- Have the roof looked at by your surveyor, and tell your buildings insurer about the panels.
- Check whether the installer's workmanship warranty is still running and insurance-backed.
