Selling a flat with a short lease in the UK
A shorter remaining lease can change who may be willing or able to buy. Before spending money or accepting a discount, compare the realistic routes available for your flat.
- Understand why lease length can affect buyer demand
- Compare extension, open-market, auction and direct-sale routes
- Consider cost, timing and uncertainty together
- Keep any partner introduction optional
The 80-year threshold matters
The Leasehold Advisory Service says a lease with less than 80 years remaining can be harder to sell or remortgage. It also notes that many mortgage lenders prefer leases with more than 80 years remaining. That does not make every sub-80-year flat unsellable, but it can reduce the pool of buyers and increase the importance of specialist advice.
Under the current statutory regime, falling below 80 years can also make a lease extension more expensive because marriage value is still relevant. The Leasehold and Freehold Reform Act 2024 contains reforms intended to remove marriage value and provide 990-year statutory extensions, but the Government said in July 2026 that those changes still require further implementation steps before coming into force.
One reform is already in force: from 31 January 2025, the previous two-year ownership requirement for statutory lease-extension claims was removed.

What to compare before choosing a route
Start with the facts
Confirm the current unexpired lease term from your documents or solicitor and understand any ground-rent or service-charge issues that could affect a buyer's decision. If the lease is approaching 80 years, timing can materially affect the extension decision.
Do not assume that a flat is unsellable simply because the lease is shorter than ideal. Different buyers and sale routes have different requirements.
Compare the whole outcome
Extending a lease may improve saleability in some cases, but it can involve valuation work, legal steps, premium costs and time. If you need to sell before completing an extension, the Leasehold Advisory Service explains that a seller may in some cases start the formal process and assign the claim to the buyer; this is something to discuss with a conveyancer.
- Expected sale price under each route
- Likely extension and legal costs
- How quickly you need certainty
- Whether likely buyers need mortgage finance
- Your tolerance for delay or renegotiation
