Before they ask:
Selling a house with solar panels — what paperwork do you need?
Expect to be asked for the MCS certificate and any feed-in tariff paperwork. If the panels were installed free under a rent-a-roof scheme, there is a lease on your roof — and that, not the panels, is what can stall the sale.
- How long
- Days, or weeks if a lease is involved
- Typical cost
- Usually nil to obtain
- Who asks
- Buyer's solicitor and lender
Solar panels generate two enquiries. One is a formality. The other has killed sales.
The formality
The MCS certificate. Microgeneration Certification Scheme certification for the installation. Asked for routinely, usually easy to find, and if it is missing the installer or the scheme may be able to help.
Feed-in tariff paperwork, if the system is in a tariff. Where a tariff is in payment it generally transfers with the property, administered by the licensed supplier. Find out who yours is now rather than in month three.
The one that matters
If the panels were installed free, under what was commonly marketed as a rent-a-roof or free solar scheme, you did not get free panels. You granted somebody a lease of your roof, typically for around 20–25 years, in exchange for them taking the generation payments.
That lease:
- Is a registered legal interest in your property
- Binds your buyer
- Has to be acceptable to your buyer’s mortgage lender
Lenders take a range of positions on roof leases, with conditions around the term, access rights, insurance and what happens if the panels need removing for roof work. Where a lease does not meet a particular lender’s requirements, the options narrow to varying the lease, buying out the panels, or finding a buyer with a different lender. All of those take time, and two of them cost money.
Why sellers get caught. The scheme was marketed as free and felt like a favour. The lease was signed years ago and filed away. It surfaces when the buyer’s solicitor reviews the title, which is well after you have accepted an offer and taken your house off the market.
What to do before you list
- Establish ownership. Did you pay for the installation, or did someone else?
- If you did not pay, find the lease. Your title documents will show it. Your conveyancer can pull it up.
- Read the buy-out clause. Many leases include a mechanism for buying the panels out. Knowing the figure before you are negotiating under pressure is worth a great deal.
- Find the MCS certificate and your tariff details.
If you own them outright
Much simpler. Gather the MCS certificate, the installation paperwork, any warranty, and the tariff details if there is one. Then it is a selling point rather than a problem — and your EPC will already be reflecting the benefit.
Common questions
How do I know if I own my panels?
If you paid for the installation, you own them. If they were fitted free and someone else receives the generation payments, they are almost certainly owned by a third party under a long lease of your roof. Your title documents will show a registered lease, and your conveyancer can check in minutes.
Why does a roof lease matter?
Because it is a legal interest in your property that binds the buyer, and the buyer's lender has to be willing to accept it. Many lenders have specific conditions about roof leases — length, access rights, removal terms. Where the lease does not meet them, the sale can stall until it is varied or the panels are bought out.
Can I transfer the feed-in tariff to the buyer?
Where a tariff is in payment it generally transfers with the property, and the administrative process sits with the licensed supplier. It is worth establishing early who administers yours and what they need, because it is a slow thing to start late.
Does an MCS certificate matter if the panels are old?
It matters for any tariff claim and it is routinely asked for regardless. If you cannot find it, the installer or the MCS scheme may be able to help, provided the installer is still trading.
