A 125-year lease can sound surprisingly short when you are about to spend a large amount of money on a home. Buyers sometimes look at the expiry date and wonder whether they are purchasing something that is already losing value.
In most cases, that concern needs putting into perspective. If a flat genuinely has around 125 years remaining today, the lease length alone is unlikely to cause an immediate problem. It should comfortably outlast any ordinary period of ownership and will usually be acceptable to mainstream mortgage lenders.
The important word, however, is remaining. A lease originally granted for 125 years does not still have 125 years left each time the property is sold. Its term continues to run down from the original commencement date.
Quick answer
Yes. A lease with 125 years remaining will ordinarily be considered a long lease and should not need extending in the foreseeable future purely because of its length. Check the actual unexpired term rather than the original term, and do not overlook ground rent, service charges, restrictions or poor building management. Mortgage lenders have different requirements, but a genuine 125-year remaining term is normally comfortably above the point at which lease length becomes a concern.

What does a 125-year lease mean?
A 125-year lease gives the leaseholder a legal interest in the property for a term of 125 years beginning on the commencement date stated in the lease.
It is important not to confuse the original term with the term remaining. The clock does not restart when the flat is sold. If a lease was granted for 125 years in 2006, it will have approximately 105 years remaining in 2026—not another 125 years from the buyer’s completion date.
| Example lease | Approximate term remaining in 2026 |
| 125 years beginning in 2026 | 125 years |
| 125 years beginning in 2006 | 105 years |
| 125 years beginning in 1986 | 85 years |
Those examples are deliberately approximate. The exact commencement date and wording of the lease must be checked.
The leasehold title register will normally give brief particulars of the lease, including its date and term. The lease itself contains the fuller description of the property, the rights granted and reserved, restrictions and financial obligations.
The government’s guidance confirms that 99, 125 and 999 years are all typical long-lease terms. The Leasehold Advisory Service lease-length checker can help establish how many years remain.
My broader leasehold property guide for England and Wales explains how leasehold ownership works.
Is a 125-year lease long enough?
For most buyers, a lease with 125 years remaining is long enough. It is a conventional long residential lease rather than a short lease approaching an urgent extension problem.
That does not make it identical to freehold ownership. The lease remains time-limited, and the leaseholder must comply with its terms. However, it would be misleading to suggest that a flat with 125 years remaining is already on the verge of becoming difficult to mortgage or sell.
Suppose someone buys the flat and owns it for 20 years. A lease that had 125 years remaining on purchase would still have about 105 years left when they came to sell. Its length would not ordinarily be the feature causing a future sale difficulty.
I have seen buyers become so preoccupied by the headline lease term that they give too little attention to matters likely to affect them much sooner: a poorly maintained roof, an escalating ground rent, an inadequate reserve fund or an expensive programme of major works. Lease length matters, but it is only one part of the picture.
Can you get a mortgage on a 125-year lease?
A lease with 125 years remaining will normally be comfortably long enough for a mainstream residential mortgage. There is, however, no single legal rule requiring every lender to accept or reject a particular term.
Lenders publish their own requirements. Some specify a minimum term remaining on completion. Others also require the lease to have a stated number of years left after the mortgage term ends. The requirements can vary according to the lender, property and mortgage product.
The UK Finance Mortgage Lenders’ Handbook contains lender-specific conveyancing instructions. Your conveyancer must check the requirements of the lender actually providing the mortgage rather than relying on a general rule found online.
Ground rent can also affect lender acceptance. A flat may have a very long lease but contain a rent that increases rapidly or becomes high in relation to the property’s value. The wording of the rent-review clause therefore matters alongside the number of years remaining.
Is 90 years the minimum mortgageable term?
No. It is not accurate to say that mortgage lenders generally stop accepting leases as soon as they fall below 90 years.
Some lenders will lend where considerably less than 90 years remain, provided their requirements are met. Others take a more cautious approach. Government guidance says lenders are typically less likely to lend where fewer than 80 years remain, but that is not a universal lending cut-off either.
The safest statement is that lender criteria differ and tend to become more restrictive as the lease shortens. A property should be checked against the proposed lender’s current policy.
Will a 125-year lease lose value?
Every lease becomes one year shorter with each passing year, but that does not mean its market value drops sharply or predictably every year.
At 125 years remaining, the landlord’s right to recover possession is so far into the future that the difference in value between 125 and 124 years will ordinarily be very small. The financial effect of the shortening term tends to become more material later.
There is no sudden legal or valuation cliff at 100 or 90 years. Buyers may begin thinking about future extension costs as the term moves closer to 80 years, but a flat does not automatically become unmortgageable or substantially less valuable the moment it passes one of those round numbers.
Value also depends on matters that have nothing to do with lease length, including location, condition, service charges, management, ground rent, building safety and the general property market.
The 80-year rule and marriage value
The most important threshold under the law currently in force is 80 years.
When a qualifying flat owner uses the statutory lease-extension process, marriage value forms part of the premium if the lease has 80 years or fewer remaining on the valuation date. The valuation date is generally the date on which the formal Section 42 notice is served.
If more than 80 years remain on that date, no marriage value is payable. If the lease has exactly 80 years remaining, marriage value can apply.
What is marriage value?
A lease extension may increase the value of a flat. Marriage value broadly represents the additional value created by combining the leaseholder’s existing interest with the landlord’s interest through the grant of the longer lease.
Under the present statutory formula, the landlord receives 50% of that marriage value. It is one part of the overall premium, alongside compensation for lost ground rent, the delayed return of the property and any other qualifying loss.
This does not mean everyone with 125 years remaining should extend immediately. It means the term should be monitored and considered again well before it reaches 80 years.
My detailed guide explains lease-extension costs, the formal process and the 80-year rule.
Should you extend a 125-year lease?
Where 125 years genuinely remain, there is usually no immediate need to extend solely because of lease length. A statutory extension involves a premium, legal and valuation expenses and, under the current rules, responsibility for specified reasonable landlord costs.
Paying those costs now may offer little practical benefit where the lease is already comfortably long. That is particularly so if the owner expects to move within an ordinary period of ownership.
The answer may be different where “125 years” describes the original lease rather than the term remaining. A 125-year lease granted 40 years ago has only about 85 years left and should be considered quite differently.
There may also be reasons to investigate an earlier extension. The owner may wish to remove ground rent through the statutory process, satisfy an unusual lender requirement or prepare for a planned sale or remortgage. Where the flat owners collectively own the freehold, they may agree to grant substantially longer leases on favourable terms.
Even then, the whole financial and legal position should be compared. An extension should solve a real problem rather than be undertaken simply because one long lease is not quite as long as another.
What matters besides lease length?
A buyer can become fixated on the number 125 and miss terms that have a much greater effect on everyday ownership.
Ground rent
Most qualifying new long residential leases granted on or after 30 June 2022 are restricted to a peppercorn ground rent. Older leases may contain continuing rent and review provisions.
Check the current rent, the review dates and the formula for increases. A lease with 125 years remaining but an onerous escalating rent may be less attractive than a somewhat shorter lease with a peppercorn rent.
The government has proposed restricting many existing ground rents. Until legislation is enacted and brought into force, buyers must assess the rent actually required by the lease rather than assuming that a future reform has already reduced it.
The official Ground Rent Act guidance explains which leases are protected by the current legislation.
Service charges and major works
The service charge may have a much more immediate effect on affordability than lease length. Review several years of accounts, the current budget, the reserve-fund balance and any proposed major works.
A flat with a 125-year lease can still carry a substantial bill for a roof, lift, windows, cladding or external repairs. My guide explains service charges and what leaseholders can challenge.
Restrictions
Check restrictions on alterations, pets, flooring, letting, holiday use and working from home. A long lease does not help if its terms prevent the use that matters to you.
Management
Find out who manages the building and how effectively. Poor record-keeping, persistent disputes and deferred maintenance can make ownership difficult even where the lease length itself is excellent.
Is a 999-year lease better?
All other things being equal, a 999-year lease provides greater long-term certainty than one granted for 125 years. The term is so long that shortening is unlikely ever to become a practical issue for the present owner or many generations of successors.
That does not make a 999-year lease a freehold. It remains leasehold, and its service-charge obligations, restrictions, repair provisions and management arrangements still apply.
Nor does it mean that a buyer should reject an otherwise suitable flat simply because its lease has 125 years remaining rather than 999. In most ordinary transactions, the quality of the lease and building management will matter more than the difference between two comfortably long terms.
A 999-year lease is sometimes informally described as a “virtual freehold”, but that is not a separate legal form of ownership.
What if the flat has a share of freehold?
“Share of freehold” usually means that the flat owner holds the lease of the flat and also has a share or membership interest in the company or group that owns the freehold.
The lease does not disappear. It still defines the flat, grants rights and regulates repairs, insurance, service charges and use of the building. A 125-year lease therefore continues to run down even though the leaseholders collectively control the freehold.
In many such buildings, the flat owners can agree to grant themselves 999-year leases or other substantial extensions for little or no premium. The transaction must still be documented properly, any mortgage lenders must be dealt with and the new leases must be registered at HM Land Registry.
Where the flat owners do not already control the freehold, they may be able to acquire it through collective enfranchisement.
What should a buyer check?
Before buying, establish the precise term remaining from the lease and title documents. Do not rely solely on an estate agent’s description saying “125-year lease”, because that may refer to the original grant.
Your conveyancer should confirm the original term, commencement date and unexpired term on completion. They should also check that the lease meets the proposed lender’s requirements and explain the ground rent, review formula, service charges, reserve fund, anticipated works and restrictions affecting your intended use.
The management information should reveal whether major expenditure is being planned, whether other leaseholders owe substantial arrears and whether disputes or building-safety concerns exist. Alterations should have the necessary landlord and planning consents, and the seller should be able to provide documents relating to any share in the freehold or management company.
The government’s guide to buying or owning a leasehold home provides a useful list of matters to investigate before committing to a purchase.
How do the leasehold reforms affect 125-year leases?
The Leasehold and Freehold Reform Act 2024 contains major reforms to lease-extension law, but several of the most publicised changes are not yet in force.
Under the law currently operating, a qualifying flat owner can obtain a statutory extension adding 90 years to the existing term and reducing ground rent to a peppercorn. The former requirement to own the flat for two years ended on 31 January 2025.
The 2024 Act provides for statutory extensions of 990 years, the abolition of marriage value and a new valuation and costs system. As at July 2026, that package has not yet commenced. The government is consulting on the valuation rates and process-cost rules needed to implement it.
The official government explanation of the forthcoming lease-extension reforms sets out the intended changes.
For an owner with 125 years remaining, those reforms are usually something to monitor rather than a reason for urgent action. The lease is comfortably above the present marriage-value threshold, leaving time to see how the new regime develops.
Frequently asked questions
Is a 125-year lease considered a long lease?
Yes. Residential leases originally granted for more than 21 years are generally treated as long leases for statutory purposes, although eligibility for particular rights can involve additional conditions. A term of 125 years remaining is also long in the ordinary property-market sense.
Is a 125-year lease good for a first-time buyer?
Its length should ordinarily be satisfactory. The buyer should still investigate ground rent, service charges, planned works, building safety, restrictions and management before deciding whether the property itself is a good purchase. In particular, check whether a Section 20 consultation is already underway or substantial works are being discussed. My guide to Section 20 notices and major works bills explains why this can matter and what the consultation process involves.
Can I get a 35-year mortgage on a 125-year lease?
By the end of a 35-year mortgage, approximately 90 years would remain. That is likely to satisfy many lenders, but the proposed lender’s current criteria must be checked.
Is a 99-year lease long enough?
A lease with 99 years actually remaining may still be readily mortgageable and saleable. It is closer to the 80-year threshold than a lease with 125 years remaining, so the owner may need to consider extension sooner.
What happens after owning a 125-year lease for 25 years?
Approximately 100 years would remain, assuming it genuinely had 125 years left when purchased. Selling the property does not restart the term.
Does marriage value apply to a 125-year lease?
No, not while more than 80 years remain at the statutory valuation date. Marriage value applies under current law where the lease has 80 years or fewer remaining.
Can I extend even though 125 years remain?
You can ask the freeholder to agree an informal extension. A qualifying flat owner may also exercise the statutory right. Whether doing so makes financial sense is a separate question.
Is a 125-year lease on a house different?
The same need to check the remaining term, ground rent and restrictions applies. However, the statutory rights for leasehold houses currently arise under different legislation from those governing flats. See my guide to leasehold houses and buying the freehold.
The sensible answer
A lease with 125 years remaining is ordinarily long enough. It should not be presented as a hidden short-lease problem or as something that naturally becomes difficult to mortgage after only a few decades.
The sensible approach is to verify the exact unexpired term, understand the lender’s criteria and then look beyond the headline number. In many cases, the service charge, management history, ground rent and condition of the building deserve far more attention than the difference between a 125-year and a substantially longer lease.
Keep the term under review, particularly as it moves closer to 80 years, but do not create urgency where none exists. At 125 years remaining, there is normally plenty of time to make a considered decision.
