Who repairs a leasehold flat balcony, what every buyer must know

Balconies sit in a genuinely awkward spot. They're attached to your flat, they feel like yours, and you're the one putting the plant pots out there. But legally, a balcony is often something else entirely.

Most leases treat the structure of a building, the external walls, the roof, the floors between flats, as the freeholder's or the landlord's responsibility to maintain. The leaseholder then pays for that maintenance through the service charge. Where a balcony sits in that picture depends entirely on the wording of your specific lease, and leases are not written to a single national template. Some are beautifully clear. Others are genuinely ambiguous, and disputes do end up in tribunal.

So before you fall in love with that south-facing terrace, you need to understand exactly what the lease says, and what it means for your wallet.

The most common approach you'll see is this. The structural slab, the concrete or steel deck that the balcony sits on, is treated as part of the building's structure and falls to the freeholder or management company to repair. The cost comes back to leaseholders via the service charge, split across all flats.

The surface finish, the tiles, decking boards, or waterproof membrane on top of that slab, is often the leaseholder's responsibility. So is anything you've added yourself, furniture, a pergola, plant boxes bolted to the railings.

The balustrade, the glass panels or metal railings around the edge, is where things get really variable. Some leases say it's part of the external fabric of the building, so the freeholder maintains it. Others treat it as part of the flat's demise, meaning it's yours to sort. A few leases are silent on it altogether, which is where arguments start.

The honest truth is that you cannot assume anything. You have to read the lease.

Since the Grenfell Tower fire in 2017, fire safety on the external fabric of buildings has been under intense scrutiny, and balconies are very much part of that picture.

The concern is combustible materials used in balcony construction, particularly timber decking and certain composite decking boards, as well as the fixings and membranes underneath them. In taller buildings, the Building Regulations now restrict the use of combustible materials on external walls and attachments, and balconies are considered part of that external envelope.

For buildings over eighteen metres, or eleven metres in some cases depending on the specific risk assessment, there are strict rules about what materials can be used. If a building has balconies clad in or finished with combustible materials, it may need remediation work. That work costs money, and leaseholders have historically been caught with enormous bills, though the Building Safety Act 2022 introduced protections and a developer remediation scheme for qualifying buildings.

If you're buying a flat in a building over eleven metres tall, ask your solicitor specifically about the building's EWS1 status, any fire risk appraisal of external walls, and whether the balcony materials have been assessed. This area of law is still developing, so confirm the current position with your solicitor before you exchange.

Even in lower-rise buildings it's worth asking whether the balcony decking material has been reviewed. Some managing agents have already required leaseholders to replace combustible timber decking. If that requirement is coming, you want to know before you buy, not after.

Start with the title register. You can download it from HM Land Registry's website for seven pounds. It confirms whether the property is leasehold, gives you the title number, and usually shows the lease length. If a copy of the lease has been filed at the Land Registry, you can download that too for seven pounds.

Once you have the lease, look for the definitions section first. It should tell you what is included in the demise, the legal description of what you're actually buying. Does it include the balcony floor, the balustrade, the airspace above? Then look at the repair covenants, the clauses that say who is responsible for repairing what. Cross-reference the two.

If the language is unclear, and it often is, don't guess. Ask your solicitor to give you a written opinion on where balcony responsibility sits. That's not an extra luxury, it's basic due diligence.

Also ask the seller or their solicitor for the last three years of service charge accounts and any section twenty notices. A section twenty notice is the formal consultation a freeholder must carry out before doing major works costing more than two hundred and fifty pounds per leaseholder. If balcony repairs are on the horizon, there may already be a notice in the pipeline.

Here's what I'd want answered on any flat with a balcony before I committed.

1. 1Does the lease clearly define whether the balcony, including the structural slab, the surface finish, and the balustrade, falls within the demise of the flat or the common parts?
2. 2Who is responsible for repairing each of those elements under the repair covenants in the lease?
3. 3Has the managing agent or freeholder carried out any inspection of the balcony in the last five years, and if so, what did it find?
4. 4Are there any planned or anticipated works to the balcony or the building's external fabric, and has a section twenty notice been issued or is one expected?
5. 5For buildings over eleven metres, what is the EWS1 status, has an external wall fire risk appraisal been completed, and does it cover the balcony materials?
6. 6Has the freeholder or managing agent required any leaseholder to replace or alter balcony decking or other materials for fire safety reasons?
7. 7Is there any ongoing or past dispute between leaseholders and the freeholder about balcony repair responsibility?

These aren't awkward questions. Any seller or managing agent worth dealing with should be able to answer them.

It does happen. A leaseholder notices the balcony slab is cracking, water is getting in below, and they write to the freeholder. The freeholder says it's the leaseholder's problem. The leaseholder says it's structural. Nobody fixes anything while the argument runs.

If a dispute like this is unresolved when you buy, you inherit it. That's why your solicitor should raise enquiries specifically about any known defects to the balcony and any correspondence about who is responsible for fixing them. If the seller knows about a problem and doesn't disclose it, that's a misrepresentation, but proving it after the fact is painful and expensive.

If you end up in a dispute as a leaseholder, the First-tier Tribunal (Property Chamber) in England can determine liability for service charges and, in some cases, help resolve disputes about the scope of repair obligations. But that takes time and money. Far better to get clarity before you buy.

A balcony is a genuine selling point and there's nothing wrong with wanting one. But leasehold property means shared buildings, shared responsibilities, and sometimes shared arguments about who pays for what.

The key things to take away are these. Read the lease, don't assume. Get your solicitor to confirm in writing where balcony responsibility sits. Ask about fire safety assessments if the building is over eleven metres. Check the service charge history for any sign that balcony works are coming. And never, ever exchange contracts without knowing the answers.

Done properly, none of this should kill the deal. It just means you go in with your eyes open, which is exactly where you want to be.
