What paperwork does a buyer’s solicitor ask for when a house has solar panels?

Usually the MCS certificate, the electrical installation certificate, proof the network operator was told (G98) or approved the system (G99), the warranties, and for a listed home or a borderline position, the planning and listed building consent records. If the panels are leased, the lease itself.

Do leased panels cause problems when selling?

They can. Some older schemes gave a company the right to use your roof for decades in return for the electricity. A buyer’s lender will want to read that lease, and some will not lend until it is checked or bought out. Find out early whether your panels are owned or leased.

Do export payments transfer to the new owner?

The new owner signs up for their own export tariff with their own supplier, using the system’s MCS certificate. Older feed-in tariff arrangements can transfer to the new owner through the supplier that pays them. Ask the supplier for its change-of-ownership process.

Buying or Selling a Chester Home With Solar Panels

Buying or selling a Chester home with solar panels

With thousands of solar systems across the borough, more Chester sales now include panels on the roof. A smooth sale comes down to paperwork: proof the system was certified, connected properly and, on a listed or conservation-area home, allowed. Here is what to gather or ask for.

Why this comes up more often in Chester now

Government figures count 11,740 solar PV sites in Cheshire West and Chester at the end of 2025, up from 5,759 at the end of 2019 (DESNZ). In the seven city wards 58.9% of households own their home (Census 2021), and every one of those homes with panels will one day be sold with them. Systems fitted before the Smart Export Guarantee arrived may sit under older arrangements, and some were installed on leases. The paperwork tells a buyer which kind of system they are getting.

If you are selling: the pack to gather

MCS certificate. Shows the system was installed by a certified installer and is registered. If you have lost it, the MCS database can usually provide a copy.
Electrical installation certificate. Issued for the electrical work when the system was fitted.
Grid record. The G98 notification or G99 approval from SP Energy Networks, the network operator for Chester (SPEN). Your installer should have sent you a copy.
Warranties. Panels, inverter, workmanship, and any insurance-backed guarantee policy. Some transfer automatically, some need registering in the new owner’s name.
Planning position. For most houses, a note that roof panels were permitted development is enough. For a listed home you need the planning permission and Listed Building Consent; for a borderline position, a Lawful Development Certificate if you obtained one.
Export arrangement. Who pays you for exports now, and their contact details, so the buyer can set up their own tariff.
Ownership. Confirm the panels are yours. If they are leased, provide the lease early: it is the document most likely to slow a sale.

If you are buying: the questions to ask

Owned or leased? A lease that lets a company keep the panels and the roof space for decades needs legal advice and your lender’s agreement.
Does the paperwork match the roof? Count the panels, check the inverter model against the certificate, and ask how old the inverter is: it is usually the first part to be replaced.
Was it allowed? If the house is listed, ask for the consent; check the National Heritage List if you are not sure. In one of Chester’s thirteen conservation areas, panels on a road-facing wall or balcony needed planning permission; roof panels normally did not (GPDO Part 14). See conservation areas.
What has it produced? Ask for the generation history from the inverter app or meter and compare it with the Chester figures in our output estimator for that roof direction.
Is there a battery? If so, ask for its certificate and warranty, and whether the system needed a G99 approval.
How will you be paid for exports? You set up your own export tariff with a supplier of your choice; it needs the MCS certificate and a meter that records exports (Ofgem’s SEG guidance).

Roof condition and the survey

Panels can hide the state of the roof beneath them. On Chester’s older houses, many of them roofed in slate, ask your surveyor to look at the roof around the panels and in the loft for signs of leaks around the fixings. If roof work is needed in the next few years, panels have to come off and go back on, which costs money and should be priced into your offer.

Does solar add value?

We do not publish a figure, because no reliable Chester-specific evidence exists for one. What a buyer sees is lower electricity bills for as long as the system works, paperwork that may or may not be in order, and a roof that may need attention. A well-documented, owned system on a sound roof is a selling point; an undocumented or leased one is a question for the solicitor.

If you are thinking of adding panels before you sell, read what solar costs in Chester and how to choose an installer first.
