Extending your lease is one of the most important decisions you’ll make as a leasehold property owner. A lease extension can protect your property’s value and make it easier to sell or refinance. The process might seem complicated at first but breaking it down into clear steps makes it manageable.
The entire lease extension process typically takes between six and twelve months from start to finish. Understanding what’s involved helps you plan and work with the right professionals to get it done smoothly.
Why extend your lease?
A lease is crucial to your property’s value. Most lenders won’t mortgage properties with fewer than 70 to 85 years remaining. If your lease drops below 80 years, your property becomes harder to sell, and its value can fall sharply. A buyer with a 25-year mortgage, for example, might be turned away outright if your 75-year lease would fall below their lender’s requirements during the mortgage term.
Extending your lease early, before it falls below 80 years, protects your investment and keeps your options open. It also means you’ll avoid additional costs that come with shorter leases.
Who can extend their lease?
You can now apply for a lease extension as soon as your name appears on the Land Registry register. The requirement to have owned your property for two years was removed on 31 January 2025, so you no longer need to wait.
Your lease must have been granted for more than 21 years originally. You also won’t qualify if your landlord is a charitable housing trust providing accommodation as part of their work, or if you hold a business or commercial lease. Properties within cathedral precincts or where the freehold is held by the National Trust are also excluded.
If you’re unsure whether you qualify, speak to a specialist lease extension solicitor who can check your specific situation.

The lease extension process step by step
The formal lease extension follows a structured sequence that takes you from initial valuation through to Land Registry registration. Here’s how each stage works.
Get a professional valuation
Before you do anything else, you need a professional valuation. Hire a valuation surveyor with expertise in leasehold valuation to assess the premium you should pay the freeholder. A professional valuation is essential because getting it wrong can lead to disputes with your landlord.
The surveyor looks at factors including your property’s value, how many years are left on your lease, and current market conditions. Property prices change regularly, so make sure your valuation is current and reflects 2026 conditions accurately.
Appoint a specialist solicitor
Find a lease extension solicitor with expertise in this area. Look for someone who is a member of the Association of Lease Extension Practitioners (ALEP). They’ll guide you through the legal process and handle all the paperwork.
Your solicitor will check the title register to confirm exactly how many years remain on your lease and identify the correct freeholder. This accuracy matters because mistakes in your application can delay everything.
Serve a formal notice on your freeholder
Your solicitor will prepare and serve a Section 42 notice on your freeholder. This is the formal legal notification that you’re applying for a lease extension. The notice must include your professional valuation, details about the property, and the premium you’re offering.
This notice starts a statutory timetable. Your freeholder then has 21 days to request evidence of your right to extend, and two months to serve a counter-notice setting out their response.
Negotiate the premium
Once your freeholder serves their counter-notice, you have six months to negotiate and agree on the premium price. If you and your freeholder can reach an agreement during this time, things move forward smoothly.
If you can’t agree, either party can apply to the First-tier Tribunal (Property Chamber) to settle the dispute. Tribunal cases are relatively uncommon but can be time-consuming and expensive, so most people aim to reach agreement through negotiation.
Complete the legal process
Once you’ve agreed on the premium, your solicitors work together to prepare the legal documentation for the new lease. Your solicitor will also handle any arrangements with your mortgage lender, who must provide a Deed of Substitution to move your mortgage debt to the new lease.
You’ll exchange contracts and complete the transaction. At this point, you own the new extended lease.
Register the new lease with Land Registry
Your solicitor submits the new lease to HM Land Registry for registration. This final step is important because it makes the extension official and updates the property records.
Land Registry completes about half of applications in around seven to ten months, with almost all completed within twelve to thirteen months. A few can take longer depending on how complete the application is. Once registered, your new lease is secure.
How long does the whole process take?
From start to finish, expect the process to take six to twelve months. The timeline depends on how quickly both you and your freeholder respond, how smoothly negotiations go, and whether any disputes arise.
The fastest part is the legal agreement, which follows a strict statutory timetable of around 39 weeks once your notice is validly served. The longest part is usually Land Registry registration at the end, which can take several months.
Some people manage informal lease extensions more quickly, potentially in three to four months, though these carry additional risks and aren’t legally guaranteed.
Getting the right professional help
Working with experienced professionals makes a real difference. Choose a leasehold extension solicitor and surveyor who specialise in this area and understand the current legal landscape. They’ll know about recent changes in leasehold law and can spot potential issues early.
Choosing professionals wisely can actually speed up the process. They know how to prepare applications correctly, anticipate freeholder objections, and negotiate effectively.
After your lease extension
Once the new lease is registered, your property is in a much stronger position. The longer lease improves its value and makes it easier to sell or refinance. Your mortgage lender may even offer better interest rates on a property with a longer lease.
Many people find that extending their lease early, well before it falls below 80 years, was one of the best decisions they made. It protects their property’s future and gives them peace of mind.
Getting started
If your lease is approaching the 80-year mark or lower, now is the time to start thinking about an extension. The sooner you act, the smoother the process will be.
