If you own a flat, letting your lease drop too low wipes its value quicker than a leaky roof. Yet in England and Wales, powerful laws let you extend leases for a fair price. This guide looks at whether you should extend and how it works.


This guide's been written in association with Consumer Futures and with kind help from The Leasehold Advisory Service, Crosse + Crosse Solicitors and Clarke Mairs LLP.

Should I extend my lease?

There are over four million leasehold flats in England and Wales and it's the most common form of flat ownership.

If you own a leasehold flat, you effectively rent it for a certain amount of time. You own the right to hang out there, but not the building itself. Scottish and Northern Irish leasehold laws differ.

  • Read more on the four main types of home ownership in England and Wales.

    • Freehold

      This where you own your pad outright and the land it stands on. You pay maintenance cost and you will not have to extend your lease. As a rule of thumb, most houses are freehold and most flats leasehold.

    • Leasehold

      If you own a leasehold flat, you effectively rent it for a period of time, specified on the lease. You should have the option to extend this lease, if that's something you need or want to do. The freeholder (or landlord) is usually responsible for insuring the building and maintaining communal areas.

    • Share of freehold

      This is where a building's flat-owners club together to each buy a share of the freehold. They are responsible for insuring and maintaining the building.

      You still need to extend the lease. In this case you can usually extend it to 999 years for free (if the other flat-owners who own the freehold agree). The only cost would be legal fees.

    • Commonhold

      Commonhold was introduced in 2002 and usually applies to new-build flats. It's similar to share of freehold, but there is no lease, so the years don't count down. Few have taken up this form of property ownership, so it is relatively untested.

Who can extend?

Under the 1993 Leasehold Reform Act, most flat-owners are legally entitled to get 90 years added to their lease at a fair market price. In a nutshell …

To be legally entitled to extend, you need to have owned the flat for at least two years.

You don't need to have lived there, just owned. Though for very short leases, the price rockets.

Should you extend?

Extending a shorter lease to a decent length can add thousands to your property's marketing value. Generally, the shorter the lease, the lower the asking price.

When you extend, it's usually by 90 years.

extending lease

Check how long you've got left. If your lease is under 70 years, mortgage rates may at best increase. It will be virtually unmortgageable under 60, so you will struggle to remortgage. If you want to sell, you'll probably have to flog to a cash buyer or shift at auction.

If you've more than 90 years remaining, the value added to the flat may only be a smidgen more than your costs - see potential added values in our table. (Though, of course, who knows what little things can sway people to pay more for one property than another?)

There's no urgency for those with 90 years or more left who are staying put. However, everyone – whether selling or staying – should start thinking about this once their lease gets to 83ish years.

If your lease is ticking down to 80 years, READ ON!

We want to sear a point onto your brain. There is a magic number of years at which leases become much pricier to extend. That magic number is:

80 magic number

Freeholders sit around praying you let your lease drop to 80 years or less, as then they rake in the cash. This is because after that you will pay 50% of the flat's 'marriage value' on top of the the usual lease extension price. Marriage value is the amount of extra value a lease extension would add to your property.

If your lease has 83 years left, it's time to really start looking seriously into this.

If you're a flat-hunter, alarm bells should screech if a lease is nearing or below 80 years – don't just accept estate agents' promises of easy extensions.

You have to have owned the flat for two years before you can extend. A seller can get the ball rolling and pass the rights to the purchaser. But if a buyer waits until they've completed the purchase, it'll be another two years before they've a right to extend.

Typical cost to extend lease on £200,000 flat by 90 years

LEASE LENGTH EXTENSION COST PROFESSIONAL FEES (1) TOTAL POTENTIAL ADDED VALUE (2)
95 years £5,000 £2,500 £7,500 £5,000
85 years £6,000 £2,500 £8,500 £10,000
79 years £8,500 £2,500 £10,500 £16,000
70 years £14,000 £2,500 £16,500 £26,000
60 years £24,000 £2,500 £26,500 £38,000
Typical cost to add 90 years to a lease, cost based on Leasehold Advisory Service data. Costs are per flat and can vary dramatically. Based on a £200,000 flat (£200,000 is its value with 999 year lease) with £200 annual ground rent. 1) This includes the valuation fee and freeholder's legal costs. 2) Estimates by Kinleigh Folkard & Hayward. These are typical values for straightward cases and will vary.

What if I've got a short lease?

Extending short leases is pricey – we're talking tens of thousands. If your lease is shorter than 60 years, talk to a solicitor about how much it will cost to extend (the leasehold calculators won't work below 60 years). Excellent legal advice is a must.

Some inspiration ...

Here are a few MoneySavers' experiences, just remember this won't work out for everyone. If you've extended your lease, post your experiences, good & bad, in the Extend Your Lease discussion.

Extending my lease stacked up. The total cost was about £8,000, plus £2,000 in professional fees. Letting the lease slip to 80 years would have made it £15,000 more expensive to extend. And the property would have been harder to sell and worth less. The fall in value would have been more than I spent. Galling as it was to spend the money, it made financial sense.

MoneySaver 'the flying pig', Jan 2012

Our lease extension cost £15,000 including legal fees. We sold for £165,000, but just after the flat below ours without a lease extension sold for £130,000. Extending meant we weren't limited to cash buyers.

I would not buy a leasehold flat again – too much grief and cost associated with extending the lease (the leaseholder basically has you over a barrel, especially if they know you want to move).

MoneySaver 'cuthbert_the_octopus', Jan 2012

We've just sold our London flat. It had a 47 year lease and we were told no mortgage lenders would lend on such a short lease, so we paid to extend it. It cost us £41,000 plus legal fees. The valuation without the lease extension was £197,000, and we sold for just under £250,000 [about £10,000 profit].

Want to ditch your freeholder too?

Leaseholders must pay ground rent (usually small) and service charges (often a fair whack) to the landlord.

Frankly, some freeholders would take the pennies off a dead man's eyes, charging £10,000s extra for repairs and picking pricey insurance policies paying the most commission.

The good news is a building's flat-owners are often legally entitled to buy the freehold and take over the building's management. It's usually then easy and cheap to extend the lease to 999 years at the same time.

As a rough rule of thumb, the cost of a share of the freehold for one flat (excluding legal fees) is similar to extending a lease by 90 years. Alternatively, you may still have a legal right to manage your building.

So if you want more control over your building too and at least 50% of the building's flats want to take part, read our Buy Your Freehold guide.

How much will it cost to extend my lease?

The price depends on several variables, including the flat's value, the lease length and ground rent. It also depends on your negotiations.

Bear in mind leasehold law is hideously complicated so costs can vary dramatically.

Ask other residents in the building how much their extensions cost, as this provides a useful guide.

Other costs to factor in

On top of the cost of the lease extension itself, you pay a few other fees:

extra lease extension costs

  • Legal fees

    You'll need to pay your legal fees, plus the freeholder's reasonable costs and valuation fees. Importantly, this does not include the freeholders' legal costs for negotiating the price or for dealing with court or First-Tier Tribunal applications.

  • Valuation fees

    A surveyor will need to visit your home to put a figure on the lease extension. These valuations typically cost about £400 to £900, depending on your flat's value.

  • Stamp duty

    Stamp duty applies to lease extensions in the same way as any other home purchase. However, this is unlikely to affect most flats, as you don't have to pay anything if the extension price is £125,000 or less. If it's more, use our Stamp Duty Calculator to see how much you'll pay.

How to pay for it

Hopefully, extending your lease will ultimately add value, but don't take out credit cards or loans to do it.

Mortgage broker London & Country says most lenders will extend a mortgage to pay for a lease extension. You'd still need enough room on the mortgage to cover it, in terms of spare equity, and be able to meet the repayments though. Though lenders may be cautious if you've an extremely short lease.

Plus, remember, borrowing's cost isn't just about the rate, it's about how long it's for. The longer, the costlier – and most mortgages are over much longer periods than loans or credit cards. Do your sums with our Mortgage Calculator and see the Remortgage Guide.

Step-by-step guide to extending your lease

The lease extension process can go slower than a year in prison, so if you're thinking of selling your home, start early. Though it's worth noting that the clock stops counting once you serve the notice, so if you file at 81 years, the lease won't tick down to 80.

Just a note that in this guide, the word freeholder means the person who flat owners pay service charge to (otherwise known as the 'landlord'). Sometimes landlords pay rent to an even bigger company that owns the freehold and is legally known as the 'freeholder'. We've chosen to use the word 'freeholder' instead of landlord in all cases to avoid confusion.

  • Step 1. Find a solicitor

    The Leasehold Advisory Service lists solicitors specialising in the field. Also try the Association of Leasehold Enfranchisement Practitioners' website.

    There can be huge cost differences between different conveyancers, so ensure you test the market. The less the freeholder tries to drag it out, the cheaper your legal costs.

    They needn't be based nearby. If you live in an expensive city such as London, an out-of-town solicitor could be much cheaper. Check whether the fee is fixed or an estimate.

  • Step 2. Value the lease

    Professional valuation advice is crucial. A surveyor will give the best indication of what you should pay for the lease extension.

    The Leasehold Advisory Service lists surveyors who specialise in leasehold. Lease extension valuations typically cost about £400 to £900, depending on your flat's value.

  • Step 3. Negotiate the price

    Your solicitor may approach the freeholder informally first. If the freeholder isn't up for it, the solicitor will serve a 'tenant's notice', telling them that you're applying for extension.

    The freeholder will now ask for a deposit. This will either be 10% of the lease cost stated in the notice or £250, whichever is greater.

    At this stage, the freeholder will hopefully accept your offer. If not, they'll come back with a counter offer, and your solicitor will negotiate back and forth with the freeholder.

    If that doesn't work, you can go to First-Tier Tribunal, the arbiter of leasehold disputes, though in many cases this isn't necessary.

  • Step 4. Apply to a tribunal

    If you and the freeholder are in a stand-off, you can apply to a First-Tier Tribunal to have the matter settled. Your solicitor's legal fees will usually be higher if you go to the First-Tier Tribunal.

    Once you apply, you usually need to wait about four months for a hearing. After that, the First-Tier Tribunal simply writes to you to say how much it's decided you'll pay for the extension.

    The Leasehold Advisory Service publishes lists of past First-Tier Tribunal lease extension decisions, though you will have to be dedicated to wade through the legal jargon.

Here's a quick Q&A on extending your lease. If you've further questions, please add them to the Extend Your Lease discussion.

  • What if I can't find the freeholder?

    As long as the property is registered, for a small fee, you can inspect the Land Register and obtain copies of the entry relating to the freehold. This should give you all the details you need to track down the freeholder who can grant the lease extension - your solicitor will help with all this. You can also try and find their details via rights to information under Landlord and Tenant legislation.

    If, despite your best efforts, you are unable to locate the freeholder, your solicitor can apply to the county court for an order that means you can extend the lease. You'll need to prove to the court that you did your best to try and track them down. Once you've done this, you'll then be able to get the price fixed at a First-Tier Tribunal.

  • Can I extend the lease on a freehold house?

    Freehold houses come under different law. You usually only have the right to extend your lease by 50 years, rather than 90 years with flats. The freeholder could grant more than 50 years if they want, but it's up to them.

    Leasehold houses are rare and the legislation is tricky, so seek advice from a solicitor with experience in the area. In recent years, a number of new-build houses have been sold, controversially, as leaseholds.

    However, as the laws on freehold houses are more restrictive, most owners tend to buy their freehold rather than extend their lease. For full info on freehold houses, go to the Leasehold Advisory Service site.

  • Can you profit from flats with super-short leases?

    The shorter the lease, the cheaper the property. Some properties with super-short 20-40 years leases sell at bargain basement prices. It's more common in swanky parts of London.

    However, if you've owned the property for two years, you've a legal right to extend the lease. Extending short leases is pricey – we're talking tens of thousands – but sometimes the combined cost of the cheap property and the lease extension adds up to less than you could flog it for once it has a 99 or 125-year lease.

    It also mean that you could end up paying less stamp duty too.

    Who can do this?

    Though occasionally lucrative, this technique is tricky. You'll need to be cash buyer looking for an investment, as you're more likely to see Jordan in a nun's habit than get a mortgage on a short-lease property.

    This is an advanced way investors make cash from buying and selling properties. Many people who do this are ex-solicitors and accountants; you can get burned if you don't know what you're doing.

    How it works

    A quick tip to find short-lease properties is to pop the following into Google:

    site:rightmove.co.uk "short lease"

    You'll then need a quote from a solicitor on how much it will cost to extend (the leasehold calculators won't work below 60 years). Excellent legal advice is a must.

    Leases with less than 70 years left to run should be approached with caution. Worst case scenario is that you are left with a lemon, a short leasehold property that you can't afford to extend the lease on. As the lease shortens, the flat's appeal to potential buyers reduces.
