Leasehold flats make up over half of all property transactions in London. The leasehold system in England and Wales is undergoing reform — but in the meantime, buying a leasehold property still requires detailed due diligence that goes well beyond what any mortgage lender or estate agent will flag. This is our definitive checklist.
Leasehold flats require specific pre-purchase checks beyond a standard property survey.
The 10 Essential Checks Before Buying a Leasehold Flat
This is the single most important financial factor in a leasehold purchase. Check the unexpired term (not the original term). Below 85 years and lenders start to get cautious; below 80 years the cost of extending rises dramatically; below 70 years many lenders will not lend at all. Read our Lease Extension Guide for full detail.
Ground rent has been a major scandal in the leasehold sector. Leases granted before 2022 can contain onerous ground rent provisions — some doubling every 10–25 years. Under the Leasehold Reform (Ground Rent) Act 2022, new leases must have zero ground rent, but old leases with escalating ground rents still affect thousands of London flats. Check the ground rent amount and any review mechanism very carefully.
Service charges pay for the maintenance, insurance, and management of the building. Ask for three years' service charge accounts. Look for: irregular or rapidly increasing charges; large special levies or "major works" contributions; a management company with a poor track record. Budgeted vs actual costs can reveal how well the building is managed.
A well-managed building will have a sinking fund (reserve fund) built up over time to pay for major works without special levies. Ask what is held in the reserve fund and compare it to the anticipated future works. A building with no reserve fund may be heading for a significant special levy for, say, roof replacement or external decoration.
Many leasehold flat buyers mistakenly believe that because the landlord maintains the building, they don't need a survey. Wrong. A Level 2 HomeBuyer Report on your specific flat is essential — damp, defective windows, leaks from the flat above, poor conversion works, and structural issues within the flat all need to be identified before you buy.
The lease sets out what you can and cannot do with the property. Restrictions can include: no pets, no subletting without consent, restrictions on alterations, noise covenants. Have your solicitor review the lease carefully and flag any covenants that might affect how you want to use the property.
Is the freeholder a local authority, a well-run residents' management company, or a distant investment company with a history of disputes? Check whether there are any current disputes between leaseholders and the freeholder. A confrontational or absentee freeholder can make building maintenance difficult and lease extensions expensive.
The Grenfell Tower fire has transformed the regulatory landscape for flats above 11 metres (approximately 4 storeys) in blocks built or refurbished since the 1980s. Check whether the building requires an EWS1 (External Wall System) certificate, whether any remediation works are required, and who bears the cost. This is critical for mortgage lending and insurance.
The LPE1 (Leasehold Property Enquiries) form and management pack should be provided by the seller's solicitor. This contains key information including: current service charge and ground rent amounts; known major works; insurance details; any existing disputes; compliance certificates. Review it carefully — this is the most comprehensive source of leasehold information available.
The Leasehold and Freehold Reform Act 2024 brings significant changes to the leasehold system in England. These include: right to extend to 990 years; removal of two-year ownership qualification; abolition of marriage value below 80 years. Many provisions are yet to come into force — your solicitor and surveyor should advise on the current position.
Frequently Asked Questions — Leasehold Flat Purchases
Do I need a survey on a leasehold flat if the building is maintained by the management company?
Yes. The management company maintains the building fabric, but defects within your specific flat — damp, defective services, poor conversion works, leaks from above — are your responsibility. A survey on the flat is essential regardless of the building management arrangements.
What is a "virtual freehold" and is it better?
A "virtual freehold" is an informal term sometimes used to describe a very long lease (999 years or 125 years remaining). These are generally preferable to short leases, but the quality of the leasehold documentation and management arrangements still matters. Don't assume a long lease means no leasehold issues.
Can I buy the freehold with other leaseholders in the building?
If more than 50% of leaseholders in the building agree, you may have the statutory right to collectively purchase the freehold — a process known as "collective enfranchisement." This gives the leaseholders control over the building management and makes lease extensions far simpler. Your solicitor can advise on the process and eligibility.
How do I find out if there are cladding issues on a flat I want to buy?
Your solicitor should raise cladding enquiries with the seller's solicitors. Ask specifically whether an EWS1 certificate has been obtained; whether the building is registered with the Building Safety Regulator; and whether any remediation works are planned, in progress, or completed. For blocks built or significantly refurbished between 1980–2000, this is a particularly important check.
