A lease runs down every year, and as it gets shorter the flat can become harder to sell or mortgage, and more expensive to extend. We explain your options in plain English, tell you up front which costs are ours and which are not, and take care of the legal work from start to finish.

When to extend your lease

Your lease is nearing 80 years

Under the current rules, extending below 80 years usually costs more, because the landlord can claim a share of the increase in value.

You plan to sell

Buyers and their lenders prefer a longer lease, so extending first can make your flat easier to sell.

You want to remortgage

Some lenders will not lend on a short lease, or offer worse terms.

Your ground rent is rising

The statutory route usually reduces the ground rent to nothing as well as adding years.

How it works

  1. Get your instant quoteSee our fixed fee and the costs that sit alongside it, then accept online when you are ready.
  2. We check your lease and advise on the routeWe review your lease and title, explain the statutory and informal routes, and suggest a valuer to advise on the premium.
  3. Notice or negotiationUnder the statutory route we serve formal notice on your landlord. Under the informal route we negotiate terms directly.
  4. Agree the premium and the new leaseWe deal with the landlord’s solicitors and check the new lease carefully, including any changes the landlord asks for.
  5. Complete and registerOnce everything is agreed and paid, we complete the new lease and register it at HM Land Registry.

An agreed extension can be quick. The statutory route follows set timetables and can take several months, depending mostly on the landlord.

Having worked with AJ over the last few months I can highly recommend him and his firm. Highly professional and explaining each step only the way.

Tess S.Google review · Nov 2026

I cannot recommend Judge Law highly enough. Going through a divorce is never easy, particularly when there is a child and complex matters involved, but the support and guidance I received throughout the process made a difficult time much easier to navigate. I felt listened to…

Raydwaan K.Google review · Oct 2026

I can’t recommend Judge Law highly enough. We were referred to them and chose to instruct Judge Law because of their responsiveness — we had a very short window to complete due to lender demands, and they gave us confidence from the outset that they could move at the pace…

Lease extension FAQs

When should I extend my lease?
Ideally before it falls below 80 years, because under the current rules the premium usually rises sharply below that point. If you are planning to sell or remortgage, extending first can also make that easier.
How much does a lease extension cost?
Our legal fee is a fixed £900 plus VAT. The biggest cost is usually the premium paid to the landlord, which depends on a valuation of your flat. Your quote sets out each cost separately. Our guide on lease extension costs explains how the premium is worked out.
Statutory or informal: which route is better?
The statutory route gives you a legal right to an extension on set terms, usually 90 extra years at no ground rent, with a tribunal to settle disputes. The informal route can be quicker, but the terms are only what the landlord agrees to, so they need checking carefully. We will recommend the route that suits you.
Can I sell my flat while extending the lease?
Yes. With the statutory route, the right to the extension can usually be passed to your buyer as part of the sale. We can advise on the best way to do this.
Do I need my lender’s permission?
Usually, yes. Most mortgage lenders need to agree to the new lease. We deal with your lender for you.
Will the new leasehold laws change things?
The Leasehold and Freehold Reform Act 2024 will change how lease extensions work, including how premiums are calculated. Some of the changes are not yet in force. We will tell you which rules apply to you when you instruct us.
