Leasehold Basics for Flat Buyers
When you buy a flat, you almost certainly buy a leasehold interest. This means you own the right to live in the flat for a fixed number of years (the lease term), while the freeholder owns the building and the land. The lease is a legal contract that governs what you can and can't do, what you pay, and what happens when the lease runs out.
The key number is the remaining lease length. Anything above 90 years is generally fine. Between 80 and 90, you should budget for a lease extension within a few years. Below 80, most mortgage lenders won't lend — and the cost of extending rises sharply because you have to pay 'marriage value' to the freeholder.
Service Charges and Ground Rent
Service charges pay for communal maintenance — cleaning, gardening, lifts, building insurance, and major works. They vary enormously: a small, well-run block might charge £1,000/year, while a large development with a concierge, gym, and underground car park could charge £5,000–£8,000/year.
Ground rent is a separate annual payment to the freeholder. For leases granted after 30 June 2022, ground rent must be zero (peppercorn) under the Leasehold Reform (Ground Rent) Act 2022. Older leases may have escalating ground rent clauses — check these carefully.
| Charge type | Typical range | What to check |
|---|---|---|
| Service charge | £1,000–£5,000/yr | 3 years of accounts, reserve fund balance, planned major works |
| Ground rent | £0–£500/yr | Review clause type (fixed, RPI, doubling), new leases must be zero |
| Admin/consent fees | £50–£250 each | Fees for subletting permission, alteration consent, etc. |
| Major works levy | Variable | Any Section 20 notices served or planned |
Cladding and Fire Safety
Since the Grenfell Tower tragedy in 2017, cladding and fire safety have become critical issues for flat buyers. Buildings over 11 metres (roughly 5 storeys) must have an External Wall System (EWS1) form confirming the cladding is safe — without one, most lenders won't offer a mortgage.
Even for buildings under 11 metres, your solicitor should check for any fire safety issues. The Building Safety Act 2022 created a framework for remediation, and qualifying leaseholders in buildings over 11 metres are generally protected from paying for cladding removal. But non-cladding fire safety defects (compartmentation, fire doors, alarm systems) may still require leaseholder contributions.
Management Companies
Who manages the building matters as much as the flat itself. There are three common arrangements: a professional managing agent appointed by the freeholder, a residents' management company (RMC) where leaseholders control management, or a right-to-manage company where leaseholders have taken over management from the freeholder.
Resident-managed buildings tend to have lower, more transparent service charges. Professionally managed buildings can be efficient but are sometimes used by freeholders to generate excessive fees. Check the management structure before buying and talk to existing residents if possible.
What Your Solicitor Should Check
Flat conveyancing is more complex than house conveyancing and should cost more. A solicitor who quotes the same fee for a flat as a house probably isn't going to give the lease the attention it deserves. Expect to pay £1,200–£2,000 for flat conveyancing.
- ▸Lease length: Remaining term and any extension provisions
- ▸Ground rent clause: Fixed, RPI-linked, or escalating — and the review period
- ▸Service charge accounts: Three years of accounts plus reserve fund position
- ▸Section 20 notices: Any major works planned or recently completed
- ▸Building insurance: Who arranges it, what it covers, and at what cost
- ▸Restrictive covenants: Pets, subletting, alterations, short-term lets
- ▸Fire safety: EWS1 form, fire risk assessment, any remediation works
Financing a Flat Purchase
Some lenders have restrictions on flats that don't apply to houses. Common issues include: flats above commercial premises (takeaways, pubs, and petrol stations are particular concerns), studio flats under 30 square metres, flats in buildings with more than a certain proportion of rental tenants, and ex-local authority flats on certain estates.
Get a mortgage agreement in principle before making offers, and tell your broker it's a flat — they'll check for lender restrictions specific to your situation.
