Lease Extension
1. What Is A Property Lease?
A lease simply means the right to occupy a property (usually a flat) for a period, which is generally set at 99 or 125 years. At the end of this time, although you can stay on as a tenant, the freeholder (freehold enfranchisement) will own your property.
2. Can I Extend My Lease?
The good news is that, as long as you have owned (but not necessarily lived in) your property for at least two years, you have a right to a lease extension for an additional 90 years at a peppercorn (zero) ground rent.
But there are exceptions. You can’t force the freeholder to extend a lease if:
- The majority of the leaseholders have applied to obtain the freehold
- Your lease has already ended
- You have sublet your home on a lease of at least 21 years
- The lease was originally granted for less than 21 years
- The freeholder is a charitable housing trust, the National Trust, the Crown (although they may agree), or the property is in a cathedral precinct
- If your freeholder wants to demolish or redevelop the property (in which case you would be entitled to compensation)
Should your freeholder refuse to extend your lease for any other reason than those listed above, get advice – they may be wrong (more on advice below).
3. Why Extend? Value
The most immediate reason for extending is that a short lease can seriously affect the value of your property.
A a flat with a lease of 100 years is worth roughly the same as a property on a freehold. But an apartment on a lease of 60 years, could be valued at approximately 60 per cent of the freehold price.
In practice, however, property values are more likely to be worked out at the freehold price, minus the estimated cost of extending the lease.
But bear in mind that if you wait until you have less than 80 years to go, buying lease extensions becomes more expensive (under 80 years and you have to pay so-called Marriage Value – more on this below).
4. Why Extend a Lease? Saleability
The second reason for extending a lease is saleability. Wealthy home hunters looking for a London pied-à-terre are more likely to accept a shorter lease, and can usually access specialist mortgage lenders who are happy to lend on short leases. But they are in the minority.
If you’re selling a flat in Fife or an apartment in Acton, most buyers will be scared off by a short lease, and they may also find that they can’t get a mortgage from the high street lenders.
A quick phone around reveals that the Woolwich doesn’t lend on property with a lease less than 30 years longer than the term of the mortgage (making it 55 years on an average 25-year mortgage).
The Halifax asks for 35 years longer (so, 60 years), and the Bristol and West draws the line at 70-year leases.
So, particularly if your lease is less than 70 years, it may make sense to apply for an extension before marketing your property.
5. Saleability and Assignment
Buying an extension is a costly business, and it can also take anything between two and six months – not good news if you’re low on funds and in a hurry to sell your flat.
There is another way, known as assignment. The seller begins the legal process to extend the lease, but assigns the right to the incoming leaseholder, who can complete it when they take ownership.
So, instead of having to wait two years to extend a lease, the purchaser can buy an extension straight away, which should leave both buyer and mortgage company happy.
6. How To Extend
There are at least two professionals whose services you’re likely to need when extending a lease.
Firstly, a valuer, usually a surveyor. A surveyor will be able to provide you with best and worst case estimates on the value of an extension, advise you on the amount of money you should offer the freeholder, and help you to negotiate an agreement. If you can’t agree a figure, the valuer will represent you at a Leasehold Valuation Tribunal (LVT).
Secondly, you will need a legal representative – either a solicitor or a licensed conveyancer. The solicitor or conveyancer will prepare the information you need for the application, serve the notice on the landlord, answer requests for information, and conveyance the new lease. There are also various specialist companies who will do the whole lot for you.
7. How Much Will It Cost?
How much the extension is worth is difficult to estimate accurately.
The value consists of three main amounts. The first two are to compensate the landlord for loss of ground rent during the rest of the existing term of the lease, and for not receiving possession of the property at the end of the term.
Thirdly, where the lease has less than 80 years to go, there is what’s known as a ‘marriage value’, which is arrived at by deducting the value of the property before the extension from the value afterwards, plus the value of the landlord’s interest.
Leasehold Advisory Service, the information service for leaseholders, gives an example of a flat with a 68-year unexpired lease, on a ground rent of £50 pa, with a current value of £150k, and an improved value of £165k. An extension of 90 years is likely to cost £8,250.
But the same property, on a lease with only 35 years to run, could set you back a whopping £55,368.
However, if the current lease is 95 years (and therefore attracts no ‘marriage value’) the cost of an extension would be only around £734.
In addition, the leaseholder is liable for both parties’ legal and valuation costs, unless the matter ends up at the LVT, who may apportion the costs differently.
Although it may be an expensive business, remember that you are adding value to your property, and, in addition, you will no longer have to pay ground rent.
8. Valuation Problems
Stories abound of leaseholders who have successfully negotiated the cost of a lease extension down, in some cases to half of the original figure. It can be useful to engage a Lease Extension Specialists when negotiating with landlords to minimse the cost.
But if you can’t agree on a price, you can turn to the LVT – The Leasehold Valuation Tribunal. They will come up with a figure based on what they consider reasonable, including making a costs order if either party is acting unreasonably.
9. Bought A Flat With A Short Lease?
As a new leaseholder you don’t have an automatic right to an extension but, if your freeholder is amenable, you can try and negotiate one before the end of the initial two-year period.
If you face problems agreeing a figure, however, you won’t be able to turn to the LVT for help.
10. Use It, Don’t Lose It!
Remember – if you wait until your lease ends your freeholder will be under no obligation to negotiate an extension, and you could become an assured tenant, rather than the owner of your home.

I have 51 unexpired years on my lease of 99 years, what would be the cost of the extension. The property is valued at £140000.
For a fair idea, you can estimate by summarizing this way:
It will be compensation for loss of ground rent income to be paid under the current lease, together with the loss of the right to receive the value of the flat at the end of the current lease.
Or in other words, it is the difference between the value of landlord’s interest under the present lease and the value of interest after the grant of new lease with the additional 90 years. Landlord is also entitled to receive a share of marriage value (a hidden value indicating the increase of property’s value as a result of grant of new lease).
I have applied to extend my lease. I have 62 unexpired years of the 99 years. What would the cost of the extension. The property is valued at £75000.
