Every year your lease gets shorter, your property gets harder to sell and more expensive to extend. Below 80 years, costs escalate sharply. The Leasehold Reform Act 2024 changes the rules - but it's not in force yet.
This guide is for general information only - not legal advice. Always seek professional advice before acting.
Thinking of buying a leasehold flat? Lease length changes everything: under 80 years it gets sharply more expensive to extend, and most lenders won't lend below 70 years. Read this page for the extension cost, then read our pre-purchase checklist before you exchange.
Don't have a copy of your lease?
Most leaseholders never see the original after the conveyancing pack. The good news: leases are public documents. Order a copy from HM Land Registry for £7, emailed within 24 hours. You only need your address.
Get your lease from HMLR →Your property's value is directly tied to the length of your lease. Below 80 years, mortgage lenders refuse to lend and buyers walk away. Understanding the process, the costs, and the new law is essential.
Below 80 years, "marriage value"Marriage value is the increase in the property's value once the lease is extended. Under the Leasehold Reform, Housing and Urban Development Act 1993, the freeholder is entitled to 50% of this increase once the lease falls below 80 years. Leasehold Knowledge applies - your freeholder is entitled to half the increase in property value. A lease at 75 years can cost tens of thousands more to extend than one at 85 years. Every year you delay makes it worse.
Lease extension premiums increase every year your lease gets shorter. Waiting even 2-3 years can add thousands. Professional valuation fees, legal costs, and the premium itself all add up. Acting early is almost always cheaper.
The Leasehold and Freehold Reform Act 2024Received Royal Assent on 24 May 2024. Extends lease extensions to 990 years at peppercorn ground rent and abolishes marriage value. Most provisions require secondary legislation before coming into force. House of Commons Library abolishes marriage value and extends the standard term to 990 years at zero ground rent. But most provisions are not yet in force. Implementation timelines remain uncertain after legal challenges caused delays.
Most lenders require at least 85 years remainingMortgage lender requirements vary, but most require a minimum of 85 years unexpired at the time of application. Below 70 years, very few lenders will consider the property. Homeowners Alliance on the lease at the time of application. Below 70 years, very few will lend at all. Short leases reduce your property's market value significantly and limit your buyer pool to cash purchasers.

If your freeholder does not agree to your proposed premium, you can apply to the First-tier Tribunal (Property Chamber)The First-tier Tribunal (Property Chamber) determines lease extension premiums where the parties cannot agree. Most cases settle before a full hearing. GOV.UK for a determination. Most cases settle before tribunal.
⚠️ Important: If the new Act's provisions are not yet in force when you need to extend, you'll be extending under the existing law - including marriage value. Don't assume the new rules apply. Check the current implementation status and seek professional advice.
Ask LEASE-iQ:
Lease length directly affects property value, mortgage eligibility, and extension cost.
The two-year ownership requirementRemoved on 31 January 2025 by the Leasehold and Freehold Reform Act 2024 (Commencement No 2) Regulations 2025. Leaseholders can now serve notice immediately. Boyes Turner for lease extension has already been removed (31 January 2025). Other key provisions, including abolition of marriage valueThe LFRA 2024 abolishes the requirement to pay marriage value on leases below 80 years.

At least half of qualifying tenants must participate. Legislation.gov.uk (buying the freehold) might be more appropriate for the building.

Most freeholders will engage with you when you request a lease extension. Some won't. Some will try to make it harder than it needs to be. Here's how to recognise the common tactics and what actually works against them.
Silence. They are ignoring your letters. They are hoping you will give up. Most leaseholders do. Put everything in writing. Recorded delivery. Keep copies. Silence is not a response. It is actually in your favour.
Delay. They are saying they need to check with their solicitors, or they need more time to think. Set deadlines in every letter. If they do not respond within your deadline, proceed to serving a formal Section 42 notice. Do not let them stall indefinitely.
Intimidation. They are threatening to forfeit your lease or take legal action against you. Forfeiture for exercising a statutory right is extremely unlikely to succeed in court. The law specifically protects you from retaliation. Do not be frightened by this. Get professional advice and proceed.
Inflated premium offers. They are claiming a premium price that is far higher than you expected. Get your own valuation from a RICS surveyor. If you cannot agree, either of you can apply to the First-tier Tribunal, which will determine a fair price based on the evidence.
They claim they are selling the freehold. This may trigger your right of first refusal under the Landlord and Tenant Act 1987. Get legal advice immediately. This is time-sensitive.
Always communicate in writing. Emails are fine but follow up with a letter for anything formal. Do not have important conversations on the phone and hope they remember what was said. They won't.
Be polite but firm. Do not apologise for exercising your legal rights. You are entitled to extend your lease. The freeholder is entitled to a fair premium. Both things are true. Treat it as a commercial negotiation, not a confrontation.
Set clear deadlines in every letter. 21 days is standard. Tell them what happens if they do not respond. Then follow through.
Keep a timeline of every communication. Record when you sent letters, how you sent them, what response you got, and when. The Tribunal will want to see this. It also keeps you honest and prevents misunderstandings.
Take professional advice early. A specialist leasehold solicitor costs less than you think for an initial consultation. They will tell you whether you have a strong position and what to expect from your freeholder.
If they ignore two written requests. Send a second letter noting the missed deadline and stating your intention to serve a formal Section 42 notice.
If they threaten forfeiture or harassment. Contact LEASE (the Leasehold Advisory Service) or a specialist solicitor immediately. Document every threat in writing.
If you suspect bad faith or unusual tactics. Trust your instinct. A specialist solicitor will tell you if you need to escalate or apply to the Tribunal ahead of schedule. Some freeholders try to make the process so difficult that leaseholders give up. Do not let them succeed.
Send this as your opening letter to the freeholder or their managing agent. It starts the informal conversation before you serve a formal Section 42 notice. Adapt the bracketed sections to your situation.
Tip: Upload your lease to LEASE-iQ first to check your remaining term, ground rent, and any unusual clauses that might affect the premium.
Your solicitor or surveyor will prepare the formal Section 42 notice. This cover letter accompanies it and explains in plain English what the recipient is receiving and what happens next. It reduces confusion and avoids unnecessary hostility.
Tip: The formal S42 notice itself must be prepared by a qualified professional. This cover letter accompanies it. Do not attempt to draft the statutory notice yourself.
Your letter is sent. Now what? Here is what to expect in the days and weeks that follow, and what to do when things get tricky.
You will feel anxious. This is normal. Resist the urge to chase them. Your letter set a deadline. Let it work. Do not email them asking if they got it. Do not call. Do not knock on their door. You will look desperate and undermine your position. Wait.
Good. This is the best outcome. Get any agreement in writing. Do not accept verbal promises. You forgot what they said. They will say you misunderstood. If they propose terms, take 48 hours to consider them. Check with LEASE-iQ whether their response aligns with what your lease says. If you need a solicitor's opinion, ask for it before you respond to them.
Do not panic. Aggressive responses usually mean they know you have a strong position. They are trying to frighten you into backing down. Stay polite, stay factual, keep writing. If they threaten forfeiture or legal action, get specialist advice before responding. Do not respond in anger. Your response will be used against you if this goes to the Tribunal.
This is the most common outcome. After your deadline passes (typically 21 to 28 days), you have two options.
Option 1: Send a second letter noting the missed deadline and stating your intention to proceed formally. This is formal notice. It is the first step in the statutory process. Get your solicitor to draft this.
Option 2: Skip straight to the statutory process. Serve the formal notice (for lease extension) or apply to the Tribunal (for service charges). You do not need their permission to proceed. The law gives you the right.
Lease extension negotiations: Typically take 6 to 12 months from first letter to completion. This is normal. Your freeholder is not being slow. The system is slow.
Service charge challenges at the Tribunal: Take 3 to 6 months from application to decision. Plan for it. Do not expect a quick resolution.
Challenging your freeholder feels confrontational. You live in their building. You worry about retaliation. You worry they will make your life difficult. Two things to remember.
First: The law specifically protects you from retaliation for exercising your rights. If your freeholder retaliates (raises your ground rent unfairly, refuses to do repairs, increases charges), you have a case. Document it. Talk to a solicitor.
Second: Thousands of leaseholders go through this process every year. You are not unusual and you are not being difficult. You are asserting your legal rights. That is normal.
