The government's consultation on a potential exemption from its proposed ground-rent cap closes at 11:59pm today. Behind the technical policy debate sits a more immediate problem for property owners: ground-rent clauses can already determine which mortgage lenders will accept a leasehold flat.
The Ministry of Housing, Communities and Local Government is legislating to cap ground rents on qualifying existing residential long leases at £250 a year, with the amount eventually reducing to a peppercorn after 40 years.
The policy forms part of the government's wider leasehold and commonhold reforms.
Today's consultation deadline concerns a much narrower question: whether a particular category of so-called “quid pro quo” lease should receive an exemption from the proposed cap.
These are leases where the leaseholder and freeholder specifically agreed a higher ground rent in exchange for a corresponding reduction in the premium paid for the lease.
The government consultation states that it runs for eight weeks and closes at 11:59pm on 27 August 2026.
What Is Changing?
The government is proposing a £250 annual cap on ground rent for qualifying residential long leases granted before the Leasehold Reform (Ground Rent) Act 2022 came into force, subject to limited exceptions.
The £250 cap would subsequently reduce to a peppercorn after 40 years.
The consultation closing today asks whether a narrow exemption should apply where there is clear evidence that a higher ground rent was deliberately exchanged for a lower upfront premium.
Crucially for borrowers, the proposed cap is not a reason to ignore the wording of an existing lease when buying or refinancing today.
Mortgageability Is Already Part of the Ground-Rent Problem
For mortgage borrowers, the important issue is not simply how much ground rent costs each year.
The more significant question can be whether the ground-rent provisions cause a mortgage lender to regard the property as unacceptable security.
Government analysis published alongside its ground-rent policy found that, as of January 2026, only one of 12 major lenders reviewed did not explicitly reference either £250 or 0.1% of property value within its mortgage lending rules.
The government said lenders can require additional information where ground rents exceed their thresholds, slowing transactions and reducing mortgage choice. In some circumstances, lending may not be available at all.
That turns what appears to be a relatively small annual property cost into a potentially significant financing issue.
A £500 Ground Rent on a £1m Flat Is Not Really About £500
Consider someone buying or refinancing a £1 million London apartment.
An annual ground rent of £500 may appear insignificant when set against the value of the property, the borrower's income and the size of the mortgage.
The borrower may be a high-earning executive or entrepreneur with substantial assets and excellent credit.
Yet the mortgage decision is not based solely on the borrower.
The lender must also decide whether the property itself is acceptable security.
That means the lender can consider the ground rent, how frequently it increases, the formula governing future increases and whether the lease contains a doubling provision.
A wealthy borrower can therefore be financially capable of servicing a £1 million mortgage but still encounter difficulty because of the lease attached to the flat they want to buy.
This is the distinction between borrower affordability and property mortgageability.
Current Lender Criteria Show the Problem Has Not Disappeared
Skipton Building Society's current buy-to-let criteria provide a useful live example.
Its criteria state that ground rent must not exceed 0.1% of the property value or purchase price, whichever is lower, at the time of application.
There must also be at least ten years between ground-rent increases.
Skipton says escalation linked to RPI or a similar index can be acceptable, while compounded increases are not acceptable. Clauses under which ground rent doubles or increases by more than the preceding level are also unacceptable.
Other lenders have their own criteria, and the existence of one lender's policy should not be treated as a universal market rule.
But it demonstrates the practical issue.
The mortgage assessment is not simply:
“Can the borrower afford the ground rent?”
It can instead become:
“Will the lender accept the lease containing that ground-rent provision?”
Why Ground Rent Can Reduce the Lender Universe
Mortgage lenders need to consider what happens not only when the loan begins, but throughout the mortgage term.
The property may eventually need to be sold.
The lender therefore has an interest in whether a future purchaser would be able to obtain a mortgage against it.
Lease provisions that materially restrict the future mortgage market can consequently create a security concern even where the current applicant presents little credit risk.
This is why the structure of the lease can be as important as the headline annual payment.
A Leasehold Mortgageability Review Should Look Beyond Ground Rent
For a higher-value leasehold property, the finance review may need to consider:
- current annual ground rent;
- ground rent as a percentage of the property value;
- the escalation formula;
- how frequently ground rent is reviewed;
- any doubling clause;
- remaining lease term;
- current service charge;
- known or planned major works;
- building-safety or cladding issues where relevant;
- the lender's specific leasehold criteria;
- whether a lease extension or variation is proposed; and
- whether changing the lease would materially alter the available lender market.
The Leasehold Flat Market Is Already Struggling With Liquidity
The policy debate arrives against a difficult backdrop for leasehold flats.
Recent Financial Times analysis of Zoopla data found that nearly 87% of leasehold flats listed for sale in England and Wales during the fourth quarter of 2025 remained unsold six months later.
That compared with 74% for freehold homes overall.
The FT highlighted several factors affecting the sector, including high service charges, pricing, buyer caution over leasehold risks and wider mortgage affordability.
London is particularly exposed because flats and leasehold ownership represent such a large part of its housing stock.
That does not mean every leasehold flat is difficult to sell or mortgage.
It does mean buyers should be cautious about treating the lease as a secondary legal document that can be reviewed after the finance has been arranged.
For some transactions, the lease is central to whether the finance works at all.
Prime London Buyers Can Be Particularly Exposed
The issue becomes counter-intuitive at the upper end of the market.
A buyer may be purchasing a £1 million, £2 million or £5 million apartment and assume that a relatively modest ground rent cannot possibly matter to the mortgage.
But a high property value does not make problematic lease wording irrelevant.
The borrower's financial strength may support substantial borrowing, while the property simultaneously falls outside the security criteria of some lenders.
That can be especially frustrating for international buyers who may be unfamiliar with the peculiarities of English leasehold ownership.
A foreign-national buyer may already require a lender comfortable with overseas income, limited UK credit history, international assets or a complex source of deposit.
If the lease then removes another group of lenders, the available market can narrow further.
Buy-to-Let Investors Face the Same Asset Risk
Leasehold mortgageability is equally relevant to landlords.
A landlord may have owned a flat for many years without any obvious difficulty and only discover a lender issue when attempting to remortgage.
The existing lender may have accepted the lease when the mortgage was originally granted, while a new lender applies different criteria when the property is refinanced.
That can become particularly important where the landlord wants to raise capital, refinance an entire portfolio or move away from an expensive existing facility.
If lender choice is reduced by the lease, the refinancing strategy can change materially.
The Problem Can Surface During Probate or Divorce
Leasehold mortgageability is not limited to ordinary purchases and remortgages.
It can also become relevant where property forms part of a divorce settlement or estate.
One party in a divorce may want to retain a flat and refinance the existing mortgage into their sole name.
A beneficiary may want to keep an inherited property rather than sell it.
Another beneficiary may need to be bought out.
In each case, the property may have an apparently substantial value, but the practical financing outcome depends partly on whether lenders accept the lease.
That makes mortgageability relevant to solicitors and private-client advisers before a settlement is structured around an assumed level of refinancing.
A Lease Variation Can Change the Mortgage Market
One of the most important professional-adviser implications concerns lease variations.
A solicitor or enfranchisement specialist may be negotiating a lease extension or amendment for perfectly valid legal reasons.
But changing the ground-rent terms can also change the property's financing characteristics.
If an existing clause is outside the criteria of several lenders and a legally appropriate variation removes that issue, the property may become acceptable to a wider mortgage market.
Conversely, agreeing a lease structure without checking current lender criteria can create an unintended financing problem.
The legal advice and mortgage advice remain distinct.
But they should communicate with each other.
The useful question before the documentation is finalised is:
“What will mortgage lenders make of the lease once the proposed changes have been completed?”
The Government's Reform Does Not Solve Today's Mortgage Application
The proposed ground-rent cap is potentially significant for existing leaseholders, but borrowers should distinguish future legislation from the terms on which lenders are making decisions today.
The government is legislating for the cap, and the consultation closing today concerns whether a narrow category of leases should be treated differently.
The precise legislative timetable and final provisions remain subject to the parliamentary process.
Someone purchasing or refinancing now therefore cannot simply assume that an existing ground-rent provision will cease to matter because reform is planned.
The application must still satisfy the lender's current underwriting criteria and legal requirements.
What Is a Quid Pro Quo Lease?
The consultation itself deals with a relatively specialist form of lease arrangement.
The government describes a quid pro quo lease as one where the leaseholder and freeholder specifically agreed that the premium would be lower and the ground rent higher than they otherwise would have been.
The higher ground rent therefore formed part of the economic bargain through which the lease was acquired or extended.
The government says it has not seen convincing evidence that ordinary ground rents generally operate this way and is not proposing a broad exemption.
Instead, it is considering whether a tightly defined exemption is justified where there is clear evidence of the arrangement.
Even for qualifying leases, the government's starting position in the consultation is that exempt ground rents would still reduce to a peppercorn after 40 years.
Why the £250 Figure Already Matters to Mortgage Lending
The government's own policy analysis provides useful context for why £250 has become important.
It says £250 remains a common threshold within lender policies, alongside the frequently used test of ground rent as a percentage of the property's value.
The government concluded that higher ground rents can reduce mortgage choice and affect saleability.
It also cited research from the Association of Leasehold Enfranchisement Practitioners in which 81.8% of members agreed that ground rents had a negative or undesirable effect on leasehold property sales, with mortgage availability identified as an important driver.
This helps explain why the ground-rent debate is not merely about household expenditure.
It is also about the liquidity and financeability of the underlying property.
Buyers Should Check Mortgageability Before Committing
For someone considering a leasehold purchase, particularly a high-value flat, the finance review should begin before exchange.
The mortgage adviser needs enough information about the property and lease to identify potential lender restrictions.
The solicitor remains responsible for the legal review and advice on the lease itself.
Where an unusual ground-rent provision emerges, the two processes need to connect quickly.
Waiting until late in conveyancing to discover that the selected lender will not accept the lease can lead to delays, additional valuations or legal costs, a need to switch lender, or in the worst case the loss of the transaction.
Existing Owners Should Review the Lease Before Their Mortgage Expires
The same principle applies to remortgaging.
A leasehold owner approaching the end of a fixed mortgage should not necessarily wait until the final few weeks to test the market.
If the lease contains a provision that limits lender choice, additional time may be required to establish whether another lender will accept it or whether the client needs legal advice about a possible variation.
This is particularly relevant where the borrower is also seeking substantial capital release.
The finance requirement may already narrow the lender universe. A leasehold issue can narrow it again.
Professional Advisers Can Identify the Problem Earlier
Leasehold solicitors, enfranchisement specialists, valuers, managing agents, buying agents and estate agents are often in a position to identify the issue before a mortgage broker becomes involved.
For a solicitor negotiating a lease extension, the relevant financing question is whether the proposed new lease terms will be acceptable across a sufficiently broad lender market.
For a buying agent, it may be worth identifying unusual ground-rent provisions before a client makes an unconditional commitment to a prime flat.
For an estate agent, repeated failed sales or mortgage difficulties on a particular property can be a sign that the lease needs closer investigation.
The objective is not for property professionals to provide mortgage advice outside their expertise.
It is simply to recognise when the lease and the finance need to be considered together.
A Leasehold Mortgageability Review
For higher-value leasehold properties, Willow Private Finance can assess the financing position before a purchase, refinance or proposed lease variation.
That assessment can establish which lenders may accept the current lease, whether the ground-rent provisions materially reduce lender choice and how the position interacts with the client's wider borrowing requirement.
Where the lease itself requires amendment or interpretation, the client should obtain advice from an appropriately qualified solicitor.
But the financing consequences can be modelled alongside that legal work.
That is particularly useful where a client is considering spending money on a lease extension or variation and wants to understand whether the resulting terms would improve mortgageability.
Ground-Rent Reform Is Moving Forward, but Current Leases Still Matter
Today's consultation deadline is another stage in a much larger programme of leasehold reform.
For homeowners and buyers, however, the practical financing issue is more immediate.
The government's own analysis shows how extensively lenders already use ground-rent thresholds, while current lender criteria continue to place restrictions on the level and escalation of ground rent they will accept.
At the same time, recent property-market data shows leasehold flats taking materially longer to sell than freehold homes.
For someone buying or refinancing a leasehold flat today, the sensible approach is therefore not to wait for future reform and assume the problem will disappear.
It is to establish whether the existing lease is mortgageable under today's lender criteria before the transaction becomes dependent on it.
Buying or Refinancing a Leasehold Property?
A strong income and substantial deposit do not automatically make every flat mortgageable. Ground rent, lease length, escalation clauses, service charges and the wider property can all influence which lenders will accept the security.
Willow Private Finance can review the mortgage market against the actual leasehold property and the client's borrowing requirements, helping establish whether the lease restricts lender choice before an offer, refinance or proposed lease variation is allowed to progress too far.
For prime and complex transactions, identifying an asset-level mortgage issue early can be just as important as establishing how much the client can borrow.

Ground rent can affect a mortgage for reasons that go beyond the borrower's ability to afford the annual payment.
Can ground rent stop me getting a mortgage on a leasehold flat?
Potentially. Mortgage lenders can impose additional requirements where ground rent exceeds specified monetary or percentage thresholds or where the lease contains escalation or doubling provisions they consider unacceptable. The effect depends on the lender and the precise lease terms.
What is the government's proposed £250 ground-rent cap?
The government is legislating to cap ground rents on qualifying existing residential long leases at £250 per year, with the rent reducing to a peppercorn after 40 years. The measure remains subject to the legislative process and does not mean existing leases should currently be assessed as though the cap were already in force.
What is the ground-rent consultation closing on 27 August 2026?
The consultation concerns a potential narrow exemption for so-called quid pro quo leases, where a higher ground rent was specifically agreed in return for a corresponding reduction in the premium paid for the lease. The published government consultation states that it closes at 11:59pm on 27 August 2026.
Why do mortgage lenders care about ground rent if the borrower can afford it?
Mortgage underwriting considers the property as security as well as the borrower's affordability. Ground-rent provisions can affect future saleability and mortgage availability, so a lender may regard certain lease terms as a property-security risk even where the borrower can comfortably afford the annual charge.
Can changing a lease improve mortgage options?
In some cases a suitable lease variation or extension can address a provision that restricts lender appetite, but this depends on the existing lease, the proposed amendment and lender criteria. Legal advice should be obtained before varying a lease, and the mortgage implications should ideally be checked before the new terms are agreed.
