Leasehold — The Big Issue with Flats

How Leasehold Works

Element Detail
You own The right to live there for the lease term
You don’t own The building or the land
Freeholder owns The building and land
Lease term Typically starts at 99 or 125 years
What you pay Ground rent + service charge to the freeholder
Major decisions Freeholder controls (or management company)

Lease Length Matters

Lease remaining Impact
90+ years Fine — mortgage lenders happy
80–90 years Getting short — harder to mortgage, more expensive to extend
Under 80 years Expensive to extend — “marriage value” kicks in (50% of value increase)
Under 70 years Very difficult to mortgage
Under 60 years Most lenders won’t touch it

Lease Extension Costs

Lease remaining Approximate extension cost (£250k flat)
90 years £5,000 – £10,000
80 years £10,000 – £20,000
70 years £20,000 – £40,000
60 years £30,000 – £60,000+

Leasehold reform is ongoing — the government has committed to making lease extensions cheaper and potentially scrapping ground rent for existing leases. But legislation is slow.

Service Charges

What’s typically included Cost contribution
Building maintenance Major portion
Communal cleaning Moderate
Lift maintenance Significant (high-rise)
Communal gardens Moderate
Buildings insurance Significant (you can’t choose provider)
Management company fees 10%–15% of total service charge
Sinking fund / reserve fund For future major works

Major Works — The Surprise Bill

Work Typical cost per flat
Roof replacement £3,000 – £10,000
External decorating £1,000 – £3,000
Cladding remediation £10,000 – £100,000+ (post-Grenfell)
Lift replacement £2,000 – £5,000
Window replacement £2,000 – £5,000
Plumbing/heating overhaul £2,000 – £8,000

Investment Comparison

Capital Growth

Property type Average annual growth (long-term)
Houses 4% – 6%
Flats 2% – 4%

Flats typically grow in value more slowly, partly because:

  • Lease depreciation (lease gets shorter each year)
  • Service charge concerns put off buyers
  • Oversupply of new-build flats in some areas
  • Cladding and building safety issues (post-Grenfell)

Mortgage Considerations

Factor Flat House
Deposit Same percentage Same percentage
Interest rate Sometimes slightly higher Standard
Lease length requirement Must have 70+ years remaining (ideally 80+) N/A
Non-standard construction Check if insurable Less common issue
Cladding issues Can prevent mortgage N/A
