Selling a Short Lease Flat in 2025?

News & Market Updates: 27th July 2025

If you own a short lease flat in the UK, deciding whether or not to sell in 2025 is far from straightforward. The introduction of the Leasehold and Freehold Reform Act 2024 (LAFRA) has introduced a new set of opportunities and challenges for leaseholders, but many critical aspects of the legislation remain uncertain.

Your Four Main Options

If you're considering selling your flat, you essentially have four options:

1. Sell now with a short lease

2. Sell now with an extended lease

3. Wait before selling with a short lease

4. Wait before selling with an extended lease

Each option carries its own set of pros and cons, which are summarised below.

Understanding the Legislative Landscape

The LAFRA Reforms: What We Know

• Two-Year Rule Abolished: As of January 2025, you no longer need to wait two years to extend your lease. This is a significant advantage for new owners.

• Marriage Value: The Government has confirmed that marriage value (a cost applied to leases under 80 years) will almost certainly be abolished. This could save leaseholders tens of thousands of pounds.

• Investment Rate (Reversion Discount): However, the investment rate used in lease extension calculations will now be prescribed by the Secretary of State. The rate is expected to be lower (i.e. more expensive for leaseholders), potentially offsetting the savings from abolishing marriage value.

• Consultations Underway: The Government is actively consulting on the prescribed rates and other valuation changes.

• Implementation Timeline: Secondary legislation is needed to finalise many of these reforms, and no specific dates are confirmed. The most impactful valuation reforms may not take effect until late 2025 or even 2026.

Judicial Review and Legal Uncertainty

• Some elements of the Act are under judicial review, with a key hearing scheduled for July 2025. The outcome may affect how quickly reforms can be enacted.

The Bottom Line on LAFRA

• Could it be cheaper to extend later? Possibly.

• Will it definitely be cheaper? We simply don’t know.

• Is it risky to wait? Yes, because lease length and market changes could increase your costs in the meantime.

Should You Extend Your Lease Before Selling?

Key Considerations:

• Lease Length:

  • Under 80 years: Marriage value still applies until abolished. Extending now avoids this extra cost.

  • Under 65 years: Likely unmortgageable. Selling without extending may be very difficult.

  • Over 80 years: You have more flexibility. Extending is less urgent.

• Ground Rent:

  • High ground rent can deter buyers. Reforms may cap or remove onerous ground rents, but nothing is guaranteed.

• Flat Type:

  • If the flat is already unmortgageable (e.g. small studio flatow value), lease extension might not significantly improve marketability.

• Mortgage Lender Criteria:

  • Many lenders require 70+ years remaining on the lease. Below this, your buyer pool shrinks dramatically.

• Market Conditions:

  • 2025 is a slow market with high supply and cautious buyers.

  • If mortgage rates drop or demand rises, prices may improve.

• Personal Circumstances:

  • If you need to move soon or settle an estate, waiting may not be practical.

  • If you’re not in a rush, you might have the luxury of holding out.

• Financial Constraints:

  • Extending a lease typically costs thousands to tens of thousands of pounds.

  • Costs rise as lease length shortens.

• Tax Implications:

  • CGT: Selling with a short lease may reduce your capital gains tax liability.

  • Cost of lease extension may be deductible from your CGT bill if sold after extension.

• Stamp Duty for Buyers:

  • High SDLT thresholds (especially for second homes) affect what buyers can afford to pay.

  • Buyers who are not purchasing the property as their main home (e.g. buy-to-let investors or second home owners) must pay an additional 5% SDLT surcharge on top of standard rates. This can significantly impact affordability and limit the maximum price such buyers are willing to offer.

Possible Scenarios

• Lease is under 80 years:

  • Extending now is wise if you want to maximise price and avoid marriage value.

• Lease is under 65 years:

  • Extension is almost essential if you want to sell to anyone other than a cash buyer.

• Need to sell urgently:

  • Consider selling to a cash buyer at a discount, especially if extending isn't affordable.

• Long-term investor with no immediate pressure to sell:

  • May benefit from waiting for legislative clarity, but remember that each year of delay increases the extension premium.

• Flat is unmortgageable or in poor condition:

  • Lease extension may not make a meaningful difference. Focus on pricing for cash buyers.

Conclusion

Selling a short lease flat in 2025 requires a careful balance of legal, financial, and personal considerations. The reforms introduced by LAFRA hold promise, but the uncertainty surrounding their final form and timing makes speculative waiting risky.

In simple terms:

• If you need to sell soon: Extend the lease if you can afford it, especially if it’s under 80 years.

• If you can wait: Stay informed, but be aware that time is not your friend when it comes to lease length.

• If you’re unsure: Get professional valuation advice and legal guidance to inform your strategy.

The government’s slow progress has left many leaseholders in limbo. Until full clarity emerges, each case will turn on its unique facts: the lease length, property type, marketability, your personal finances, and how much risk you're prepared to take.
