Can I put solar panels on my flat?

Usually not. In most leasehold flats the roof is not demised to you and is shared, so you do not own it and cannot fit your own panels. A maisonette with its own exclusive roof is the main exception.

Do I own the roof above my flat?

In most cases no. The roof is normally retained by the freeholder and shared across the building. Your lease and conveyancing paperwork will confirm what is demised to you.

What if I have a maisonette with my own roof?

Then a smaller system, around 2 to 3 kW, can be possible. You usually still need to check the lease and get the freeholder’s consent before going ahead.

Do block solar systems cut my electricity bill?

Not usually directly. A block system is decided by the freeholder and tends to offset communal power such as lifts and lighting, which affects the service charge rather than your own bill.

Do I need freeholder permission for solar on a leasehold home?

Yes, where a system is possible at all it almost always needs the freeholder’s written consent, and often a management company or residents’ association too. Most leases also do not grant the right to alter the structure or fix things to the roof, so the lease has to allow it.

Can a top-floor flat have solar panels?

Only if the roof above is demised to that home alone, which is unusual for a flat. The roof is normally shared and retained by the freeholder. A maisonette with its own exclusive roof is the more common case where a 2 to 3 kW system can work.

Solar panels for flats and leasehold homes

By Daniel Osei · Last checked 25 June 2026

This is the one property type where the honest answer is often no. Most people in flats do not own the roof above them, so they cannot simply fit solar. There are exceptions, and there are routes through the freeholder, but it is worth understanding why before you spend time on it.

The quick version

For a flat or leasehold home:

You usually do not own the roof, so you cannot just install
A maisonette with its own exclusive roof may fit a 2 to 3 kW system
Any roof work needs the freeholder’s consent, and often the management company’s
A block-wide system is the freeholder’s decision and usually offsets communal power, not your bill

Why most flats cannot install

In most leasehold flats the roof is not demised to you. That means it is not part of what your lease grants you, so it is not yours to alter. The roof is usually shared, and it sits with the freeholder rather than any one leaseholder.

On top of that, the lease usually does not give you the right to alter the structure or fix things to the roof, and any work affects access and the building for every resident. So for a typical flat, fitting your own panels is not on the table, and the house-by-house paybacks elsewhere on this site do not apply.

When a maisonette can

The exception is where you have an exclusive, demised roof of your own. Some maisonettes, particularly the upper one in a pair, have a roof that belongs to that home alone. In that case a smaller system, around 2 to 3 kW, can be possible, much like a small house.

Even then you usually still need to check the lease and get the freeholder’s consent, but the roof being yours is what makes it feasible at all. If you are not sure whether your roof is demised to you, the lease and your conveyancing paperwork will say.

Consent and block systems

Where a system is possible, it almost always needs the freeholder’s written consent, and often the consent of a management company or residents’ association too. The Leasehold Advisory Service has free guidance on how leasehold consent works and what your lease does and does not allow.

Some blocks do get solar, but as a building-wide project decided by the freeholder. A block system can be 10 kW or more, but it typically offsets communal power such as lifts, lighting and pumps, which feeds into the service charge rather than cutting your own electricity bill directly.
