Selling a house with solar panels
Warrington's housing market is busy, and more of the houses for sale now have panels on the roof. Whether that helps the sale depends mostly on paperwork. Here is what buyers' solicitors ask for and how to have it ready.
Owned outright: the easy case
If you paid for the panels, they are part of the house and pass to the buyer with it. The buyer's solicitor will still want evidence that they were installed properly and connected legally, and the buyer will want to know what they make and what is still under warranty. Having the documents to hand avoids weeks of back-and-forth.
Leased or "rent-a-roof" panels: the hard case
Some homes have panels that were fitted at no upfront cost in exchange for a long lease of the roof space, under which the company owns the panels and keeps the payments for the electricity they make. These arrangements were common in the early 2010s. A roof lease is a legal interest in your property, often for 20 years or more, and some mortgage lenders will not lend on a house with one, or only on conditions. If your panels are leased, find the lease now, check what it says about selling, and talk to the company early: some will sell you the panels or release the lease.
The documents to have ready
| Document | What it shows |
|---|---|
| MCS certificate | The installation was certified; the buyer needs it to apply for an export tariff |
| Electrical installation certificate | The electrical work was tested and certified |
| Network notification or approval | The network operator was told (G98) or approved the system (G99) |
| Warranties | What remains on the panels, inverter, battery and workmanship, and whether they transfer |
| Building regulations sign-off | Usually covered by the installer's competent person registration; the solicitor may ask |
If anything is missing, ask the installer for copies before you list the house. The MCS certificate can also be looked up by the installation's address through MCS.
Export payments and the buyer
A Smart Export Guarantee tariff is a contract between you and your electricity supplier, so it ends when you leave. The buyer applies for their own with the MCS certificate. If your system is old enough to be on the Feed-in Tariff scheme, those payments can transfer to the new owner; the buyer's solicitor will check the details with the supplier.
The EPC
Solar panels count towards a home's Energy Performance Certificate, which buyers see on every listing. If your EPC was done before the panels went on, a new assessment will reflect them. Bear in mind that many Warrington homes, like many across England, are rated below band C, so a better rating can help a listing stand out.

No official series picks out what panels add to a sale price, so treat any figure an agent or salesperson offers with caution. The rating is firmer ground. Semis are the commonest type of home in Warrington, and only 42.6% of those with a certificate are rated C or better (ONS), so on a typical semi a higher rating after panels can be a real point of difference in the listing.
Warranties that transfer
Panel and inverter manufacturers' warranties usually stay with the product. Workmanship warranties vary: some transfer automatically, some need registering in the new owner's name, some do not transfer at all. Check the terms and tell the buyer what applies; an insurance-backed workmanship warranty that transfers is a selling point.
If you are buying a house with panels
- Ask whether the panels are owned or leased before you make an offer.
- Ask for the documents above and check the MCS certificate matches the address.
- Ask for a year of output figures from the monitoring app and compare them with what that roof should make; see roof output in Warrington.
- Find out how old the inverter is: it may need replacing sooner than the panels.
- Set up your own export tariff after completion.

Questions about selling
Do solar panels make a house harder to sell?
Panels you own outright, with complete paperwork, rarely cause trouble. Problems usually come from missing certificates, or from "free" panels on a roof lease, where a company owns the panels and has rights over your roof for many years.
Does the export tariff transfer to the buyer?
The Smart Export Guarantee tariff is an agreement between you and your supplier, so the buyer applies for their own once they move in, using the MCS certificate you hand over. Older Feed-in Tariff payments can transfer to the new owner, which their solicitor will check.
What will the buyer's solicitor ask for?
The MCS certificate, the electrical installation certificate, proof of the network notification, the warranties, building control or competent person sign-off where relevant, and, for leased panels, the lease itself.
