The Solar-Panel Conveyancing Check 

Nearly 172,000 Solar Installations Have Been Added In 2026 But Older ‘Rent-A-Roof’ Agreements Can Still Complicate A Home Purchase

  • Nearly 172,000 solar installations were completed across the UK between January and July 2026, as Britain’s shift towards home-generated renewable energy accelerates
  • More than 19,800 rooftop solar installations were completed in July alone – equivalent to one every two minutes
  • The UK passed two million solar installations for the first time in March, while 269,000 were installed during 2025 – the highest annual total on record
  • Moving Compared warns buyers not to assume solar panels automatically belong to the homeowner, with some older systems tied to long-term roof-space leases
  • Mortgage lenders can scrutinise existing solar leases and may require agreements to be changed before they are willing to lend on the property

Britain’s roofs are changing fast. Solar deployment has reached record levels, householders are increasingly generating their own electricity and government figures show the UK has now passed two million installations. Rooftop systems can help households cut their reliance on grid electricity, with the government estimating potential savings of up to £480 a year. But what happens when you buy one of those increasingly desirable greener homes and discover the solar panels above your head do not actually belong to the seller?

Moving Compared, the home-moving platform helping buyers and sellers compare services including conveyancing and property surveys, is urging buyers to add a solar ownership check to their property due diligence. Some systems installed under earlier “rent-a-roof” arrangements involved a solar provider leasing part of the homeowner’s roof and retaining ownership of the panels. The arrangement can remain relevant when the property changes hands, meaning an apparently straightforward green feature can bring an additional legal agreement into the transaction.

The Green Upgrade With A Paper Trail

Solar itself is increasingly becoming part of the mainstream housing landscape. During 2025, the UK recorded 269,000 new solar installations, 37% more than the previous year, while around 255,000 were rooftop systems. Nine of the ten strongest months for solar deployment on record had occurred within the year to April 2026.

The legacy of earlier solar schemes, however, means buyers need to distinguish between a homeowner-owned system and one sitting under a separate roof-space agreement.

UK Finance says most lenders’ mortgage conditions require consent for a lease of roof space used for solar panels. Its Mortgage Lenders’ Handbook requires conveyancers to check registered solar roof leases against minimum lender requirements, while individual mortgage providers can impose additional conditions of their own.

The consequence can be more significant than an extra piece of paperwork. UK Finance guidance says a lender reviewing a property with an existing solar lease may ask for the agreement to be varied if it does not meet its requirements, or may choose not to lend on the property. HSBC’s current instructions, for example, state that where a roof-space lease fails to meet UK Finance standards and cannot be varied, the mortgage case cannot proceed.

Five Questions To Ask Before Buying A Home With Solar Panels

Check who owns the panels: Don’t assume they automatically come with the property.

Ask your conveyancer to check the title: Look for any roof-space lease, finance agreement or restriction.

Check how long any agreement has left to run: Older arrangements can continue after the property changes hands.

Confirm your lender is happy with the setup: Some mortgage providers have specific requirements around solar leases.

Establish who maintains or removes the panels: Buyers should know who is responsible if roof repairs are needed.
