Leasehold traps: what to check in the public record before making an offer

Leasehold property accounts for around a quarter of all homes sold in England and Wales — and a much higher proportion of flats. Leasehold ownership is fundamentally different from freehold: you own the building for a fixed period, not indefinitely, and you share the building with a freeholder whose interests may not align with yours. Getting it wrong can be expensive. Here's what to check before you offer.

Check the lease length immediately

The remaining lease term is the single most important number in a leasehold purchase. Here's why it matters:

• Below 80 years: Most mainstream mortgage lenders will not lend, or apply very restrictive terms. The property becomes significantly harder to sell.
• Below 70 years: Extending the lease becomes expensive fast. Below this point, the "marriage value" formula kicks in — when you extend, you must pay the freeholder half the value that the extension adds to the property.
• Below 60 years: Some lenders will not touch it at all. Extending can cost tens of thousands of pounds.

You can find the lease term in the HM Land Registry title register (available for £3 per title). The title also shows the start date of the lease — from which you can calculate the remaining term.

Understand the ground rent

Ground rent is an annual payment to the freeholder that comes with the lease. Recent law changes (the Leasehold Reform (Ground Rent) Act 2022) banned new residential ground rents for most properties — but existing leases are grandfathered in.

Check the current ground rent and any escalation clauses:

• Doubling ground rent: a lease that doubles ground rent every 10 or 25 years can make the property unsellable within a few decades — many major lenders now refuse them entirely.
• RPI-linked escalation: increases tied to inflation are generally acceptable to lenders but worth understanding.
• Fixed or peppercorn ground rent: the safest structure.

Ask the seller's solicitor for a full ground rent history and the escalation schedule for the remaining term.

Service charge: get three years of accounts

Service charges cover the maintenance of shared areas — the roof, external walls, communal spaces, lifts, gardens. They vary enormously: a well-managed building might charge £1,000–£2,500 per year; a poorly maintained one could charge £5,000+ and still have a major works bill looming.

Buyers are entitled to ask for:

• The last three years of service charge accounts
• The most recent budget for the current year
• Any notice of major works, Section 20 consultation, or planned large expenditure
• Whether there is a sinking or reserve fund, and its current balance

A building with no reserve fund and a crumbling roof is storing up a large special levy that will land on owners — including you if you complete.

Cladding and building safety

Following the Grenfell Tower disaster, buildings over 18 metres with unsafe cladding require an EWS1 (External Wall System) certificate from a qualified fire engineer. Without it, many lenders will not lend and the property is effectively unsellable.

For any flat above the ground floor, check:

• Whether an EWS1 has been obtained, and what its rating is (A1 or B1 are safe to lend on; A2 and B2 require remediation)
• Whether the building is registered on the Building Safety Fund (government grant for remediation)
• Whether the freeholder or managing agent has an active remediation plan
• Who will bear the cost of remediation — under the Building Safety Act 2022, qualifying leaseholders should be protected from certain remediation costs, but the protections are complex and leasehold-specific

Right to Manage and the freeholder's track record

Some blocks have exercised their Right to Manage (RTM) — leaseholders have taken over the management of the building from the freeholder. This is often a positive sign: residents managing their own building tend to be more responsive and cost-conscious. Ask whether RTM is in place and who the managing agent is. Then search for the managing agent's name and see what other residents say.

What to do with the information

A short lease, escalating ground rent, looming major works and no reserve fund can each knock tens of thousands off the fair value of a property — or make it worth avoiding entirely. Get the information before you offer, not during conveyancing, when you've already paid for surveys and have emotional investment in completing.

A Property Snapshot report surfaces the Land Registry tenure information for any property — showing whether it is freehold or leasehold and flagging the title detail — alongside the property's full data profile. It's a useful first filter before you request the full lease documentation from the seller.
