Lease Extension

Lease Extension

Why extend your lease?

If you own a leasehold flat, its value falls as the lease term shortens — and the cost of putting that right rises. The decline becomes significantly steeper once the unexpired term drops below 80 years, and most mortgage lenders are hesitant to lend on leases with less than 85 years remaining, which shrinks your pool of buyers exactly when you want to sell. Extending the lease in good time protects both the property's value and its mortgageability.

Your statutory right to a lease extension

Under the Leasehold Reform, Housing and Urban Development Act 1993, qualifying leaseholders of flats and maisonettes have the right to a statutory lease extension that delivers two things:

  1. An additional 90 years on top of the remaining term of the lease.
  2. Ground rent reduced to a peppercorn (effectively nil) for the whole of the extended term.

Following recent leasehold reforms, you no longer need to have owned the flat for two years before starting a statutory claim. Leasehold houses are dealt with under separate legislation — the Leasehold Reform Act 1967 — which offers a 50-year extension or, more commonly, the purchase of the freehold itself; and some cases fall under other regimes such as the Landlord and Tenant Act 1987. Your surveyor and solicitor will confirm which route applies before anything is served.

How the Section 42 process works

The statutory claim is started by a Section 42 notice served on the freeholder, and it runs to a fixed timetable:

  1. Lease extension valuation — an RICS Registered Valuer on the panel values the premium and advises the figure to put in the notice. The valuation date is fixed by the date of the notice.
  2. Serve the Section 42 notice — your solicitor serves the notice stating the proposed premium; the freeholder may request a deposit of 10% of that figure.
  3. Counter-notice — the freeholder must respond by the date in the notice (at least two months), usually admitting the claim but proposing a higher premium.
  4. Negotiation — the two surveyors negotiate the premium on comparable and relativity evidence.
  5. First-tier Tribunal — if terms are not agreed, either party can apply to the Tribunal between two and six months after the counter-notice, and the Tribunal determines the premium.

How is the lease extension premium valued?

A statutory premium is built from defined components: compensation for the ground rent the freeholder loses (the “term”), the value of receiving the flat back 90 years later than expected (the “reversion”), and — where the lease has dropped below 80 years — marriage value. The inputs are argued on evidence: the flat's value, relativity, deferment and capitalisation rates. That is why two valuers can legitimately open some distance apart, and why an experienced lease extension surveyor earns their fee in negotiation.

Marriage value and the 80-year rule

Once the unexpired term falls below 80 years, the freeholder becomes entitled — under the valuation regime currently in force — to half the marriage value released by the extension, and premiums jump accordingly. If your lease is anywhere near the threshold, acting before it crosses is the single most valuable piece of leasehold advice there is. Reform legislation is expected to change how premiums are calculated in future, but the changes are being phased in; claims made today are valued under the current rules.

Formal or informal route?

You can also simply ask the freeholder for an extension — the informal route. It is sometimes quicker, but it carries real risks: the freeholder is free to propose any terms, including a shorter extension or a modern ground rent that escalates, and there is no timetable forcing matters to a conclusion. The statutory route fixes the terms by law. Whichever route you take, negotiations can turn contentious, so it pays to be represented by a surveyor who handles these claims regularly — and who can take the matter to the First-tier Tribunal if agreement cannot be reached.

What your lease extension surveyor does

A Registered Valuer on the panel inspects the flat, prepares the formal Section 42 valuation, advises the premium range you should expect to settle within, and supplies the figures your solicitor needs for the notice. The same surveyor then negotiates with the freeholder's valuer — and if the case goes to the Tribunal, the panel's valuation expert witnesses prepare and present the expert evidence, so your case does not need rebuilding by a second firm.

Lease extension costs and timescales

The valuation fee is fixed and quoted before you instruct, with the report typically delivered within 3–5 working days of inspection. Under a statutory claim you will also pay the freeholder's reasonable valuation and legal fees, plus the premium itself — which is why the valuation advice at the start matters so much. From notice to completion, most claims take several months to around a year depending on how hard the premium is fought.

Frequently asked questions

What is lease valuation?

Lease valuation refers to the process of determining the worth of a lease extension. As per the Leasehold Reform, Housing and Urban Development Act (1993) leasehold owners have the right to request a 90 year extension on their lease and eliminate ground rent with payment.

To assess the value two surveyors are involved—one representing the leaseholder’s interests and another representing the freeholder’s interests. The valuation takes into account factors:

  1. Compensation for the freeholder’s loss of ground rent.
  2. Compensation for preventing the freeholder from acquiring the property for 90 years on top of the existing term.
  3. 50% of what's known as "marriage value."

If there is disagreement between both surveyors regarding the valuation the case can be referred to the First tier Tribunal for a decision.

While a leasehold calculator can provide an estimate of associated costs for extending your lease it's important to note that it may not consider all details about your property and market conditions. Therefore it should be seen as an estimate. For an assessment it is advisable to consult a qualified surveyor and legal professional who specialise in matters related to leasehold extensions. We can assist you in organising this consultation if needed.

Am I eligible for a lease extension?

To start the process of extending the lease on your property it's important to determine if you meet the criteria for a statutory lease extension. These criteria include:

  1. Owning the property for 2 years minimum.
  2. Having a lease originally granted for a term of least 21 years minimum.
  3. Ensuring that no more than 25% of the property is used for commercial purposes.
  4. Having more than two thirds of the tenants qualify as qualifying tenants.
  5. The property should have vertical division.

Please note that you won't be eligible if the freeholder operates as a charitable trust or if the lease falls under the category of a commercial lease.

You can seek assistance from your solicitor. Visit LEASE to determine if you meet these qualifications. Once you have confirmed your eligibility please get in touch with us again to arrange for a surveyor.

Is a solicitor required for lease extension?

To follow statutory procedure you would ordinarily engage a solicitor who can handle the task of serving notice. Legal advisors are usually quite helpful during the intricate negotiations that ensue.

If your property has a mortgage obtaining approval from your lender for the lease extension becomes important. Your lender may also require you to sign a Deed of Substitution to safeguard their interests in relation to the lease. The final step involves registering the lease extension with the Land Registry. The existing leasehold title will then be replaced with a new one and this registration process may take around 6 months to complete.

Considering how intricate lease extensions can be it is advisable to seek assistance from professionals such as solicitors and surveyors who have extensive experience in lease extensions.

What does a section 42 notice do?

There are two primary methods available to a leaseholder seeking an extension to their lease term:

  1. Private Agreement: the leaseholder can negotiate with the freeholder privately and reach an agreement regarding the lease extension terms.
  2. Formal Notice (Section 42 Notice): the leaseholder can choose to serve a formal notice under Section 42 of the Leasehold Reform, Housing and Urban Development Act 1993. This notice initiates the legal process for compelling the landlord to grant a lease extension.

When serving a formal notice, the leaseholder must include a future date that is at least 2 months from the date of notice by which the freeholder has to respond. This provides the freeholder with a reasonable period to consider and reply to the proposal. If the freeholder does not serve a Counter Notice by the specified date, then the leaseholder has the option to apply to the County Court. The court may grant the leaseholder a new lease on the terms proposed in their initial notice.

Should I opt for an informal route?

If you don't meet the requirements for a lease extension under the Leasehold Reform, Housing and Urban Development Act (1993) you still have the option to pursue an informal approach whereby you negotiate directly with the landlord for a lease extension. However, be aware that this alternative doesn't offer the level of protection as with the statutory process outlined in the Act. So, be mindful of the fact that by choosing the informal route the landlord has the right to decline a lease extension or impose terms without the safeguards provided by legislation.

When should I extend my lease?

You  may want to extend the lease on your home to maintain its value and provide a return on your investment. Delaying this process can lead to extra costs as explained below.

The value of leasehold properties naturally decreases over time and this can accelerate as the lease term gets shorter. Once it reaches 80 years or less, securing a mortgage becomes more difficult, thereby making it harder to sell the property when you decide.

Additionally, when you opt for a lease extension, you'll be responsible for paying 50% of the "marriage value," which is basically the increase in property value resulting from extending the lease. 

If you are considering buying a home exercise caution with properties that have less than 90 years left on their leases. Try to maintain a buffer above the 90 year threshold so that you have a decent amount of time to meet the eligibility requirements for a statutory lease extension and before incurring any potential costs associated with the marriage value.

What is procedure should I follow for lease extension?

To initiate the statutory lease extension process under the Leasehold Reform, Housing and Urban Development Act 1993, follow these steps (subject to advice by your surveyor and legal advisor):

  1. Check your eligibility: confirm you meet the criteria for a statutory lease extension under the above Act.
  2. Inform the Freeholder: notify the freeholder of your intention to extend the lease by statutory procedure.
  3. Hire a solicitor: instruct a solicitor specialising in lease extensions, preferably one who is a member of the Association of Lease Extension Practitioners (ALEP) and a good experience track record.
  4. Engage a local surveyor: instruct a knowledgeable local lease extension surveyor to conduct a valuation.
  5. Serve Tenant's Notice: this is under section 42 and outlines a formal offer for the premium derived from the valuation.
  6. Pay deposit: submit a deposit to the freeholder (either equivalent to 10% of the lease valuation offer or £250, the higher of the two) and within 14 days.
  7. Negotiate Premium: try to reach an agreeable premium if your initial offer is not accepted.
  8. Apply to Tribunal otherwise: if no agreement can been made between the parties, then the First Tier Tribunal (Property Chamber) can establish an agreeable premium.
  9. Obtain Mortgage Consent: if there is a mortgage, secure consent from the mortgage lender and arrange for signing of a Deed of Substitution.
  10. Register Lease Extension: after approximately 6 months the lease is registered with Land Registry.

How long does the lease extension process take?

Typically the entire lease extension process takes 6 12 months, but it may stretch longer if there are any disputes over the terms. So, to ensure an efficient journey, it is advisable to choose experienced professional advisors who can assist and those include solicitors and surveyors.

What is the role of the Leasehold Valuation Tribunal?

The Leasehold Valuation Tribunal (LVT), now known as the First-tier Tribunal, acts as a judicial body resembling a small court.

During a hearing representatives from both the leaseholder and freeholder state their case with evidence derived from surveyors. Thereafter, members of the Tribunal review the submitted evidence and make a decision accordingly. It is worth noting that the Tribunal has jurisdiction over the following aspects of disputes:

  • Compensation: how much needs to be paid by the landlord (freeholder).
  • Costs: assessing whether costs incurred by the landlord are reasonable and should be recovered from the tenant (leaseholder).

The primary role of the Tribunal is to provide a platform for resolving conflicts between landlords and tenants. This process aims to resolve disputes that can not be settled via negotiation.

How do you calculate marriage value?

When you extend a lease the leases value goes up while the freeholds value goes down. This difference in value, especially when the lease is short, leads to a profit called "marriage value."

Marriage value refers to the increase in the lease worth, which typically exceeds the decrease in the freehold worth.

When a lease has less than 80 years remaining then 50% of the marriage value must be paid by the leaseholder to the freeholder upon extending the lease. However, if there are still 80 years or more left on the lease then there is no obligation for the leaseholder to pay it.

From a financial perspective it makes sense to start proceedings for extending a lease before its remaining term drops below 80 years. This way the leaseholder can avoid paying costs associated with marriage value and maximise their gains from extending their lease.

Are landlords able to refuse a lease extension?

Provided you meet the qualifying criteria, you have a right to pursue a statutory lease extension under the Leasehold Reform Housing & Urban Development Act 1993.

Ordinarily, holding ownership of the property for a minimum of 2 years and possessing a long lease means you should have the right to extend and the freeholder is obligated to comply. If your freeholder proves uncooperative or does not respond to your attempts at communication, there is legal recourse to enforce your rights. In such cases, you can instruct your solicitor to serve a Tenant’s Notice and commence proceedings.

What is a right to manage?

This means that leaseholders can collectively take over management of the building instead of the landlord. You will be able to decide on how the property is run (e.g. services, maintenance and repairs).
