How This Tool Works
📋 Purpose
Most UK buyers underestimate the lifetime cost of leasehold. A £50k freehold premium is often outperformed by 20 years of ground rent escalation, service-charge inflation, major-works bills and — critically — the resale-discount cliff when the lease drops below 80 years. This tool makes the 20-year comparison explicit in pounds and pence.
⚙️ How It Works
- 1Enter prices for both a leasehold and comparable freehold.
- 2Enter lease terms — years remaining, ground rent, escalation type.
- 3Enter current service charge and expected annual inflation.
- 4Select likely major-works cycle over 20 years.
- 5Click Compare to see cumulative costs and verdict.

Quick Tips
Jump-start your understanding with these essential tips
Extension costs roughly double below 80 years. Mortgage lenders get nervous below 85 years.
A "doubling every 10 years" clause turns £250/yr into £32,000/yr by year 80. The 2022 Ground Rent Act banned this on NEW leases only.
Well above general inflation. In London developments, £2,000 service charges typically reach £3,000+ within 20 years.
Roof replacement every 20–30 years, external decoration every 5–7 years, cladding remediation still ongoing post-Grenfell.
The 2024 Reform Act makes extensions 990 years and abolishes marriage value below 80 years (when fully implemented). Watch for updates.
Step-by-Step Guide
Follow these steps to get the most from this tool
Use comparable flats — same postcode, same size, similar condition. Zoopla and Rightmove sold-price data are good sources.
This is on your lease document or EPC. If you don't know, ask the estate agent or request from Land Registry (~£7).
Check the lease carefully — peppercorn leases are worth £10,000+ more than fixed ground rents, all else equal.
Ask for the last 5 years of service charge statements. 3–5% annual rise is typical; newer developments can see 6–8%.
"Both" is conservative for a 1980s+ block with flat roof + painted external. "None" is optimistic and only realistic for newly-renovated blocks.
The chart shows cumulative running costs. The verdict quantifies lifetime difference, including resale-discount risk if the lease drops below 80 years within 20 years.

Deep dives for advanced users
Under the Leasehold Reform Housing and Urban Development Act 1993, leaseholders with 2+ years' ownership have a statutory right to extend by 90 years (to become 990 years under the 2024 Reform Act) at peppercorn ground rent. The premium is calculated by a surveyor (RICS Red Book) and has three components: deferred freehold value, capitalised ground rent, and (only below 80 years) 50% of marriage value. Below 80 years is the economic cliff — extensions jump from 5% to 10–15% of property value.
Service charges typically rise faster than CPI due to: rising insurance premiums (20%+ p.a. post-Grenfell), minimum-wage growth pushing cleaning/concierge costs, utilities for shared parts, regulatory compliance (fire safety, lift testing, asbestos surveys). Well-run blocks keep service charges to 3–4% p.a. increases. Poorly run blocks can see 7–10%, especially if sinking funds are inadequate and major works have to be Section 20-demanded.
Post-Grenfell (2017), an estimated 600,000+ UK leaseholders are in buildings with combustible cladding or related fire-safety defects. The Building Safety Act 2022 protects leaseholders in qualifying leaseholders (PPD not £100k+) from costs above £10,000–£15,000 (£50,000 London), but disputes are ongoing. If you're buying a flat in a block over 11m tall built post-2000, always request an EWS1 form — no EWS1 or a B2 rating can halve the resale price.
"Share of freehold" (the leaseholders collectively own the freehold via a management company) removes ground rent but keeps service charges — the best-of-both in most cases. Pure freehold flats are rare and legally complex (flying freeholds) because maintenance responsibility for shared structure (roof, foundations, façade) becomes unclear. When this calculator compares "freehold", it assumes a freehold HOUSE, not a freehold flat.
