Buying a Leasehold Flat: What You Should Know

18 March 2026

Written by Swinburne Maddison

When buying a property, it’s essential to understand whether you are purchasing a freehold or leasehold interest, as the two are very different and come with distinct rights and responsibilities.

Freehold vs Leasehold: What’s the Difference?

Freehold ownership means you own the property and the land it sits on outright. Your ownership is indefinite and not subject to a time limit. Freehold is most commonly associated with houses.

Leasehold, by contrast, is a long‑term right to occupy a property for a fixed period of time, often between 99 and 999 years. You own the property itself, but not the land or building structure. Leasehold ownership is most common for flats.

What Does Freehold Ownership Mean?

Freehold is the most straightforward form of home ownership. As the freeholder, you:

  • Own the property and the land outright
  • Are responsible for maintenance and repairs
  • Have control over alterations (subject to planning permission and other regulations)
  • Do not pay ground rent or service charges

What Does Leasehold Ownership Mean?

If you purchase a leasehold property, you are buying the right to live in the property for a specific period of time. This right is governed by a lease, which sets out key terms including:

  • The length of the lease
  • Ground rent and service charges
  • Restrictions on use (such as keeping pets or making alterations)
  • Your obligations as a leaseholder

Because the lease controls so many aspects of ownership, buying a leasehold property often raises additional questions and requires careful legal review.

Key Points to Check in a Lease

When purchasing a leasehold flat, there are several critical areas that should be investigated:

Lease Length

A lease with fewer than 80 years remaining can be difficult to mortgage and expensive to extend. It is vital to check the remaining term early and, where necessary, establish whether the seller has started or is willing to start the formal lease extension process.

Ground Rent

You should understand how much ground rent is payable and whether it increases over time. Some leases contain clauses where ground rent doubles or rises sharply, which can significantly affect affordability.  Most new, long-term residential leases restrict ground rent to a “peppercorn” (zero) rate, but existing leases will remain as per the terms of the lease.

Service Charges

Reviewing at least the last three years’ service charge accounts will help you understand typical costs and whether they are increasing. It’s also important to check:

  • Whether any major works are planned
  • If there is a sinking fund or reserve fund in place to help cover future repairs and reduce unexpected costs

Freeholder and Managing Agent

Identifying the freeholder and managing agent is important, as they will usually have specific requirements for new and existing leaseholders, both on purchase and on an ongoing basis.

Restrictions on Use

Finally, make sure the lease allows you to use the property as you intend. For example:

  • Do you plan to rent the property out?
  • Are short‑term lets, such as Airbnb, permitted?

Make your solicitor aware of your intentions from the outset so they can check for any relevant restrictions and advise you fully before you commit to the purchase.
