Most people buying a flat become leaseholders without fully understanding what that means for their long-term ownership rights, costs, and ability to sell. Ground rent, service charges, lease length, and the legal relationship with the freeholder can significantly affect the financial value and flexibility of your property.
This hub covers UK property ownership structures in 2026: leasehold versus freehold in practical terms, what ground rent and service charges you can be charged, how to deal with boundary disputes, and the rules around extending a lease.
Leasehold vs Freehold — The Financial Differences
| Issue | Freehold | Leasehold |
|---|---|---|
| You own the land | Yes | No |
| Time limit on ownership | No | Yes (lease length) |
| Annual ground rent | No | Possibly (on leases before June 2022) |
| Service charges | No | Usually yes (for flats) |
| Need consent for alterations | No | Usually yes |
| Lease extension required | Not applicable | Yes, if lease falls below 80 years |
| Risk at end of lease | None | Property reverts to freeholder |
For most houses, freehold is straightforward. For flats, leasehold is almost universal in England and Wales — and the management quality of the freeholder or managing agent directly impacts your annual costs and quality of life.
Ground Rent — The 2022 Reform and What It Means
The Leasehold Reform (Ground Rent) Act 2022 ended ground rent above a peppercorn on new leases from 30 June 2022. This removed one of the biggest risks in the leasehold market: escalating ground rent clauses.
Before the reform, some leases had clauses that doubled ground rent every 10 or 25 years. A £250 per year ground rent doubling every 10 years becomes £500 at year 10, £1,000 at year 20, £2,000 at year 30. At this level, properties became unmortgageable and unsaleable.
For existing leases, the old clauses remain in force. If you are buying a leasehold property, always check:
- What the current ground rent is
- Whether it has a review or escalation clause
- How many review dates remain in the term
- Whether any lender will mortgage the property given those terms
Several major lenders now refuse to lend on properties with ground rent that exceeds 0.1% of the property value or that has doubling clauses. This directly affects saleability.
Service Charges — What Is Reasonable
Service charges must be reasonably incurred, for services of a reasonable standard, and supported by a summary of costs if requested.
Your rights as a leaseholder:
- Request a written summary of relevant costs — the landlord must comply within 1 month
- Request inspection of supporting accounts and receipts
- Apply to the First-tier Tribunal (Property Chamber) if you believe charges are unreasonable
- Challenge any major works where the Section 20 consultation process was not followed
The Section 20 consultation requirement means freeholders must consult leaseholders before spending more than £250 on any single qualifying works item. Failure to consult limits the contribution they can demand to £250 per leaseholder.
Lease Extension — When to Act
The 80-year threshold is crucial for leaseholders. Below 80 years:
- Marriage value is added to the premium calculation — the freeholder gets 50% of the value the extension creates
- Mortgage lenders become reluctant or refuse to lend
- The property becomes harder to sell
| Lease remaining | Action |
|---|---|
| 100+ years | Monitor; no urgent action needed |
| 85 to 99 years | Start planning; get a valuation |
| 80 to 85 years | Act now — serve notice before falling below 80 years |
| Under 80 years | Extension is expensive; act urgently |
| Under 70 years | Many lenders refuse to mortgage; sale very difficult |
Worked Example: The 80-Year Threshold
Scenario: James owns a leasehold flat valued at £280,000 with 75 years remaining on the lease.
- At 75 years, the lease has not yet crossed the 80-year marriage value threshold
- Estimated premium: £8,000 to £15,000 (depends on ground rent and freeholder’s valuation)
- Solicitor and surveyor fees: £3,000 to £4,000
- Total cost: approximately £11,000 to £19,000
If James waits until the lease reaches 72 years, marriage value applies. The same extension could cost £20,000 to £35,000 in premium alone — total with fees: £25,000 to £40,000.
Action: James should instruct a solicitor to serve a Section 42 notice now while above 80 years.
Boundary Disputes — Practical Guidance
Boundary disputes are among the most costly neighbour disagreements. The average contested boundary dispute reaching court costs each party £20,000 to £50,000 in legal fees — often exceeding the value of the land in dispute.
Steps before taking legal action:
- Obtain the Land Registry title plan for both properties (£3 per plan from Land Registry online)
- Look for physical evidence: original deeds, historical OS maps, photographs
- Check whether conveyance documents contain a T mark indicating boundary maintenance responsibility
- Instruct a RICS-accredited boundary surveyor to prepare an expert report
- Attempt mediation before instructing solicitors for litigation
Most disputes that reach independent expert level resolve without court proceedings.
