Short Lease: Extend Now or Wait for Reform?

A short lease creates a difficult choice. Waiting reduces the years remaining and may restrict mortgageability, but forthcoming legislative reform could also reduce the eventual cost of a statutory lease extension. Neither outcome should be presented as certain.

The flat may look no different as the lease term falls, but its legal and financial profile changes. A lender that would accept the property today may not accept it when the owner wants to sell or remortgage. At the same time, the price of a future statutory extension may be affected by reforms that have been enacted but not yet fully brought into force.

The central question is therefore not simply whether the buyer can obtain a mortgage now. It is whether the remaining lease term gives the buyer a realistic and affordable route to ownership, refinancing and resale over the years ahead.

What is a short lease?

There is no single lease length at which every lender, valuer and buyer reaches the same conclusion. Mortgage lenders publish their own minimum requirements. Some focus on the number of years remaining at completion. Others require a specified period to remain after the end of the mortgage term. Some apply both tests or require a case to be referred.

A lease may therefore satisfy one lender while failing another. It may also be acceptable for a shorter mortgage but not for the term requested by a particular borrower.

This makes labels such as short, acceptable or mortgageable dangerously incomplete unless they identify:

• the unexpired lease term;
• the mortgage lender involved;
• the requested mortgage term;
• the lender requirements in force at the time;
• the cost and availability of a lease extension; and
• the likely position when the property is sold or refinanced.

The lease has an expiry date even when the mortgage does not

A buyer may be concentrating on the monthly mortgage payment, purchase price and immediate condition of the flat. The lease term can appear to be a distant problem, particularly where several decades remain.

But every year of ownership reduces the remaining term. If the buyer takes a long mortgage, the lender must consider what security will remain at the end of that mortgage. A future buyer’s lender will conduct the same exercise using the shorter term then available.

This is the link between mortgageability and practical marketability. A flat does not need to be completely unmortgageable before the lease length affects its value. A reduced choice of lenders can mean a reduced choice of buyers.

Could waiting make the extension cheaper?

Potentially, yes. The Leasehold and Freehold Reform Act 2024 provides for reforms intended to change the statutory valuation framework, including the removal of marriage value and prescribed assumptions relevant to calculating the premium. If those provisions are commenced on favourable terms, some leaseholders, particularly those with leases of 80 years or fewer, may pay less than under the existing calculation.

But the amount of any saving cannot presently be assumed. The detailed valuation rates and other technical provisions still require implementation. The commencement date, final regulations, litigation and the facts of the particular lease can all affect the outcome.

Waiting therefore involves competing considerations:

• the remaining lease term continues to fall;
• the choice of mortgage lenders or purchasers may narrow;
• a planned sale or remortgage may have to be postponed;
• the present statutory premium may increase as the term reduces;
• future reform could reduce the premium payable under the statutory route; and
• there is no guarantee about when every reform will commence or its financial effect on a particular lease.

The decision is not simply extend now or inevitably pay more later. It is a decision about paying under a known current regime or waiting for a potentially more favourable regime while accepting the market and timing risks created by a shorter lease.

Leasehold reform makes individual advice more important

The Leasehold and Freehold Reform Act 2024 provides for significant changes to lease extensions and enfranchisement. One important measure is already in force: from 31 January 2025, a leaseholder no longer has to satisfy the previous two year ownership qualification before making a statutory lease extension or enfranchisement claim.

Other headline reforms require further implementation. In July 2026, the Government confirmed that technical work, consultation and secondary legislation were still required before the new valuation and extension arrangements could operate. These include the proposed 990 year standard extension and changes affecting the calculation of premiums.

A buyer should not assume that every announced reform can already be relied upon, or that waiting will necessarily be cheaper. Equally, the buyer should not be told that delay must increase the eventual premium without considering the proposed reforms. The commencement position and the available statutory and negotiated routes should be checked when advice is given.

What should be investigated before exchange?

Before becoming contractually committed, a buyer and conveyancer should establish:

• the exact commencement date and original term of the lease;
• the unexpired term on the proposed completion date;
• whether the mortgage lender’s current requirements are satisfied;
• whether the valuer has commented on the lease length;
• whether the seller has started or can start an extension process;
• whether an informal extension has been offered and on what terms;
• the likely premium and professional costs, based on specialist advice;
• the ground rent and other terms proposed for any extended lease;
• how long the process is likely to take; and
• whether the purchase price properly reflects the short lease.

An informal offer from the freeholder should not be assessed by looking only at the additional years. Changes to ground rent, review clauses or other lease terms may affect the long term value and mortgageability of the property.

A mortgage offer answers only today’s question

The fact that the buyer has obtained a mortgage offer may appear reassuring. It confirms that the particular lender is prepared to proceed on the information and conditions before it at that time. It does not establish that the flat will remain acceptable to the wider lending market.

Different lenders can impose different minimum lease requirements, and those requirements can change. Our earlier report that Leeds Building Society had increased its minimum lease requirement provides an historical example of why lender policy cannot be treated as static.

The broader issue is explored in Leasehold Regret: Why So Many Buyers Discover the Real Cost Too Late. Lease length is one of several matters that may look manageable at purchase but become commercially significant when the owner later tries to move.

What should the Report on Title explain?

A report that merely reproduces the commencement date, original term and years remaining may be factually accurate but practically inadequate.

The buyer needs the information placed in context. That may include:

• whether the lender’s minimum requirement is only narrowly satisfied;
• how many years may remain after the intended ownership period;
• why a reduced lender pool can affect resale;
• that delay can reduce mortgageability even if reform later reduces the extension premium;
• that extending now provides greater certainty but may mean proceeding under the existing valuation regime;
• that waiting may produce a lower premium but carries legislative, timing and market risks;
• that a valuation from an enfranchisement specialist may be appropriate;
• that proposed reforms should not be treated as operative until commenced; and
• whether the buyer should renegotiate, require an extension or reconsider the purchase.

The advice should reflect the buyer’s plans. A client intending to retain the property for twenty years may face a different risk from a client expecting to sell within two years, even though both are buying the same lease on the same day.

When the problem appears years later

A short lease problem commonly emerges when the owner applies for a remortgage or accepts an offer from a buyer whose lender will not proceed. The owner may then discover that an extension is necessary before the transaction can continue.

At that point, the original purchase file may answer important questions. What lease term was reported? Was the lender’s position explained? Was the future reduction in mortgageability addressed? Was an extension discussed, valued or reflected in the price?

When I Bought explains short lease problems discovered after purchase and the documents and advice that may need to be examined when a sale or remortgage has become difficult.
