Property Foundations

Buying a Leasehold Flat

A leasehold flat is not the same purchase as a freehold house. You are buying a diminishing asset governed by a legal contract with a third party, so a handful of checks before you offer can save you thousands later. Here is what to look at.

1. Before you offer

Before you fall in love with a flat, ask the estate agent for three numbers: the years remaining on the lease, the annual service charge, and the ground rent. These three figures affect mortgageability, resale value and your monthly costs more than almost anything else about the property.

  • Lease length. Below 80 years, extending becomes significantly more expensive because of marriage value, and below roughly 70 years, some lenders will decline to mortgage the property at all.
  • Service charge. Check it against regional averages and ask for at least two years of accounts, not just the current demand.
  • Ground rent. Leases granted before the Leasehold Reform (Ground Rent) Act 2022 may still have escalating or "doubling" clauses, which some lenders now refuse to mortgage.

2. The management information pack (LPE1)

Once you have an offer accepted, your solicitor requests a management pack from the seller's freeholder or managing agent — usually the standard LPE1 form. This sets out the ground rent, service charge accounts, any arrears on the flat, planned or recent major works, and confirmation of building insurance.

This pack often takes four to eight weeks to arrive, which is the single biggest source of delay in flat purchases. Ask your solicitor to chase it in writing every one to two weeks rather than waiting for updates.

Pro Tip

Ask your solicitor to specifically flag anything in the pack about upcoming Section 20 major works — these can mean a large, unexpected bill lands on your desk shortly after you complete.

3. Questions worth asking directly

  • Who is the freeholder, and who manages the building day to day? A responsive, reputable managing agent is worth almost as much as a good lease.
  • Are there any planned major works? Roof, lift or exterior works can mean bills running into thousands of pounds per flat.
  • Has a Section 20 notice been served? If so, you may be liable for a share of the cost even as the incoming owner, depending on timing.
  • What does the service charge actually cover? Buildings insurance, a sinking fund, cleaning, gardening — get an itemised breakdown, not just the total.
  • Is there a building safety issue? For buildings over 11 metres, ask whether an EWS1 form or Leaseholder Deed of Certificate is required and available — see our cladding & building safety guide.

4. Mortgage lender requirements

Requirement Typical lender position
Unexpired lease term Most lenders want at least 70 to 85 years remaining at the end of the mortgage term, not just today.
Ground rent Many lenders now decline leases where ground rent exceeds 0.1%–0.25% of the property value, or where it doubles on a short cycle.
Building safety Taller buildings may require an EWS1 form or equivalent certification before funds are released.
Minimum lease term at application Some high-street lenders will not lend on flats with fewer than 40 to 55 years remaining at all.

Ask your mortgage broker to confirm your specific lender's leasehold policy before you commit to a survey or valuation fee.

5. Red flags to watch for

  • A lease under 80 years with no discount reflected in the price. You will likely need to fund an extension shortly after buying.
  • Unusually high or rapidly rising service charges with no itemised explanation.
  • Ground rent that doubles every 10 to 15 years. These leases can be very difficult to mortgage or resell.
  • A freeholder who will not respond to enquiries before you have even exchanged contracts — a sign of things to come.
  • Cladding or fire safety issues without a resolved EWS1 or remediation plan in place.
