Understanding Lease Extensions

Simply put, a leasehold property is a long-term rental agreement between the owner of the land (the freeholder) and you (the leaseholder). This agreement states the term of the lease (how many years you will rent the property) and how much rent you will pay the freeholder each year.

The Leasehole Extension Process Explained

The Lease Laws Amendment Act 1993 gives the lessee the right to extend the lease up to 90 years and to reduce the ground rent to a pepper (nominal amount). The process is as follows:


  • You must own the property for at least 2 years.
  • The lease term must be less than 80 years (70 years in some cases) remaining.


  • Notice: You may want to inform the freeholder of your intention to extend the lease by giving a section 42 notice.
  • Negotiation: This involves you and the freeholder talking about how much you will pay (premium) to extend the lease. Both of you can hire a surveyor to assess the property and determine the appropriate premium.
  • Contract: If you both agree on the premium, make a contract. If you do not agree, you can approach the Leasehold Valuation Tribunal (LVT), which will determine the premium.
  • Completion: Once the premium is fixed, the legal works are completed and the lease is officially extended.
