Leasehold Reform Faces Fresh Dispute Over Extension Costs as Consultation Nears Its Close

Leasehold reform has become the subject of fresh disagreement just before a government consultation closes, with campaigners questioning whether the proposed approach to valuation will deliver sufficiently lower costs for leaseholders.

The Times reported on 19 October that ministers face criticism over their position on the rates used to calculate lease-extension and freehold-purchase premiums. The dispute concerns how much value is assigned to the interests a freeholder gives up.

For someone buying or refinancing a flat, that may sound remote from the mortgage decision. In practice, the cost of extending a lease can change the cash required, the price worth paying and the lending arrangements needed to complete a transaction.

The policy outcome remains unresolved. Buyers and owners therefore face a familiar but important distinction: a potentially more favourable future system is not yet a financing solution for a property transaction taking place now.

Two Technical Rates Sit at the Centre of the Dispute

The capitalisation rate is used to value the freeholder’s future ground-rent income. The deferment rate is used to translate the value of the freeholder’s interest at the end of the lease into a present-day amount.

The Leasehold Advisory Service explains that, all else being equal, higher rates generally produce a lower premium for the leaseholder; lower rates generally produce a higher premium.

These are valuation inputs, not mortgage interest rates. A change in either does not directly change the rate charged on a borrower’s home loan.

The government’s consultation sets out different approaches. One option considers retaining the established deferment rates associated with the Sportelli decision—4.75% for houses and 5% for flats—while other approaches consider updating or replacing the methodology.

The government’s stated position is that prescribing rates is not, in itself, intended to create further premium reductions or compensate freeholders for other reforms. Campaigners want a different outcome from the exercise. The Times reports calls for materially higher rates to reduce the amounts leaseholders pay.

For borrowers, the significance is the uncertainty over the final bill. A future reform cannot yet be converted into a reliable saving for an individual flat without knowing the eventual rules and the property’s valuation details.

The Announcement and the Law in Force Are Not the Same Thing

Some leasehold changes have already taken effect. Others remain unimplemented. Treating the entire reform programme as though it has already changed every lease-extension calculation risks a costly misunderstanding.

The Leasehold Advisory Service’s current reform guidance identifies the proposed 990-year statutory extension and abolition of marriage value as changes not yet implemented.

For qualifying flats, the existing formal route generally adds 90 years to the remaining term and reduces ground rent to a peppercorn. The two-year ownership requirement was removed on 31 January 2025; eligible registered owners no longer have to wait two years before beginning that process.

Removing that waiting period does not settle the premium, shorten every negotiation or guarantee that an extension can be completed within a buyer’s preferred timetable.

For an active purchase, the relevant question is which legal route is available and how it fits the transaction—not simply whether reform has been announced.

A £900,000 Flat Can Have a Financing Problem Despite a Strong Buyer

Consider a hypothetical buyer agreeing to pay £900,000 for a London flat with 78 years remaining on the lease. They have sufficient income and plan to contribute £300,000 towards the purchase price, leaving a £600,000 mortgage requirement before other costs.

On those figures, the borrowing represents approximately 66.7% of the price. The deposit and income may look comfortable. However, neither establishes the lease-extension cost or confirms that the preferred lender will accept the property.

If the buyer’s solicitor identifies a material extension requirement, the budget needs another component. The premium, professional fees and timing of payment must be considered alongside acquisition taxes, conveyancing costs and any planned refurbishment.

The buyer cannot safely assume that a mortgage will automatically increase to absorb those costs. Nor can they assume that an eventual increase in the property’s value will provide cash at the point the premium becomes payable.

This is how a lease issue becomes a financing issue: the borrower may remain perfectly creditworthy while the proposed transaction no longer fits the original cash plan.

Eighty Years Is Not a Universal Mortgage Cutoff

The 80-year threshold attracts attention because of its role in lease-extension valuation under the current framework. It should not be mistaken for a single rule determining whether every lender will offer a mortgage.

Mortgage providers set their own requirements for the remaining lease, the term left when the mortgage ends, the loan-to-value ratio and other property characteristics.

Nationwide’s published intermediary criteria illustrate the distinction. For England and Wales, its general requirements include at least 55 years remaining at application and 30 years after the mortgage term ends. For loans above 85% loan-to-value, it specifies at least 90 years at application. Other requirements and valuation considerations still apply.

Those figures are an example, not a recommendation or confirmation that the hypothetical flat would qualify. They demonstrate why a blanket statement that a lease below 80 years is unmortgageable would be wrong.

The reverse assumption is equally unhelpful. A lender’s willingness to lend does not establish that the buyer has allowed enough for a future extension or that the purchase price represents good value.

The Purchase Price and the Extension Need to Be Considered Together

A short lease can be reflected in the asking price, but a discount is not automatically evidence of a bargain. The relevant comparison is the overall cost of acquiring the property on the intended terms.

That includes the agreed price, the extension premium where applicable, professional costs and the funding needed to complete the legal process. Any expected value after extension should be supported by appropriate valuation advice.

A buyer may seek a price reduction, ask the seller to complete an extension or explore a coordinated purchase and extension. Each route has practical consequences for timing, cash and lender approval.

A seller’s willingness to negotiate is only one part of the solution. The lender and conveyancer must also be able to complete on the agreed basis.

A Longer Lease Does Not Automatically Resolve Every Lending Concern

The number of years remaining is important, but it is not the only feature of a lease that can affect borrowing. Ground-rent provisions, review mechanisms and other legal terms may also require scrutiny.

Service charges and anticipated major works create separate financial considerations. An extension premium should not be treated as a substitute for understanding the building’s ongoing costs.

Where a freeholder proposes an informal extension, the terms need to be examined in full. The offer should not be judged solely by the additional years or the upfront price.

A lender may have specific requirements for the extension route and resulting lease. Nationwide’s published guidance, for example, states that lease extensions must be completed under the Leasehold Reform Act. An arrangement that appears acceptable between buyer and freeholder may therefore still need a different lending assessment.

This is why the mortgage adviser, solicitor and valuer need to work from the same proposed documents rather than separate summaries of what the parties hope to agree.

Remortgagers Face the Same Underlying Question

The issue is not confined to purchases. An owner may reach the end of a fixed rate with a shorter remaining lease than when the original mortgage was arranged.

A new lender will assess the property under its current requirements. A product switch with the existing lender may follow a different process, but it does not extend the lease or remove a future valuation issue.

An owner hoping to raise money for an extension needs to establish both the borrowing available and when it can be released. The financing cannot depend on the extended lease being in place if the owner first needs that same advance to pay for the extension, unless the lender and legal arrangements expressly accommodate the sequence.

That is a transaction-design problem as much as a rate comparison. A low-priced mortgage is of limited use if its conditions cannot be satisfied in the order the legal process requires.

Prime Property Makes the Cash Consequences More Significant

In higher-value transactions, the lease can influence a substantial amount of capital. A buyer with considerable wealth may still prefer not to commit additional cash unexpectedly or sell investments on a timetable dictated by the purchase.

The starting point remains a professional assessment of the property and extension. A premium should not be guessed from the asking price and remaining term alone.

A specialist valuer considers the relevant lease provisions, ground rent and valuation assumptions. The mortgage lender’s valuation serves a different purpose and should not be assumed to replace that advice.

For clients buying a prime London apartment, Willow’s complex property finance review can consider the borrowing within the wider capital plan. That does not remove the legal issue; it helps establish how an agreed legal solution can be funded.

The Dispute Makes Waiting a Decision That Needs Evidence

The possibility of cheaper extensions gives some owners a reason to consider waiting. But that choice needs to be weighed against the remaining lease, any planned sale or remortgage and the consequences of delay.

An owner with no immediate transaction may have different priorities from a seller whose buyer needs an acceptable lease now. Neither position supports a universal instruction to extend immediately or postpone everything until reform is complete.

The sensible comparison starts with a current professional assessment. It then considers the uncertain future outcome without treating a potential saving as money already available.

The consultation deadline creates an opportunity for leaseholders and professionals to submit their views through the government’s published process. It does not create a deadline by which an individual owner must extend a lease.

The Mortgage Decision Still Has to Work Under Today’s Rules

The fresh controversy exposes an important gap between the political promise of simpler, cheaper lease extensions and the decisions facing people transacting now.

For a buyer, the answer may involve a different purchase price, a seller-funded extension or a lending arrangement coordinated with legal completion. For an existing owner, it may involve planning the extension alongside the next refinancing.

Willow’s role is to assess the borrowing while the solicitor establishes the legal position and the specialist valuer assesses the premium. That coordination can distinguish a workable transaction from one relying on assumptions about future reform.

The policy debate may change the economics of leasehold ownership. Until the final rules are known and implemented, a sound financing plan needs to stand on the lease and costs that actually apply.
