Lease Extension for Leasehold Houses

1 July 2026

Written by Chris Ross

If you own a leasehold house, you may be considering your options as the lease term reduces. Unlike flats, leasehold houses are governed by different legislation, which can impact your rights and the long-term value of your property.

This guide breaks down how lease extensions for houses work, who qualifies, and whether extending your lease is the right move.

Your Rights as a Leaseholder of a House

If your property qualifies under the Leasehold Reform Act 1967, you have two main options which are to either extend your lease or buy the freehold (known as enfranchisement).

If you choose to extend your lease you can add 50 years to your existing term. Your ground rent will change to a “modern ground rent”, calculated using a statutory formula. The new lease will largely mirror the original terms, aside from these changes.

It’s worth noting that lease extensions for houses are generally less favourable than those for flats. For example, a flat lease extension adds 90 years and reduces ground rent to zero. Because of this, many leaseholders consider buying the freehold instead, as it can offer better long-term value and control.

Who Qualifies?

You will usually qualify for a lease extension if you hold a long lease (originally granted for more than 21 years), and if the property is your home.

You may not qualify if the property is used for business purposes, your landlord is a charitable housing trust and the property is provided for charitable use, or if the lease does not meet the statutory criteria.

The Cost of Extending a House Lease

One key difference from flat extensions is cost structure. There is no premium payable for extending the lease of a house by 50 years through the formal legal route.

However, the ground rent converts to a modern ground rent, which is often higher than the existing rent. This rent is based on factors such as the letting value of the land and can be reviewed after 25 years.

With this in mind, budget for your own legal and valuation fees and your landlord’s reasonable professional costs.

The Process Explained

Extending your lease follows a formal legal procedure:

  1. Serve a statutory notice on your landlord under the 1967 Act
  2. If you qualify, the landlord must grant a new lease with an additional 50 years and largely the same terms as your existing lease
  3. If terms cannot be agreed, either party can apply to the First-tier Tribunal (Property Chamber) for a decision

Other Considerations

Before proceeding, keep the following in mind:

  • Mortgage lenders will usually need to consent to the lease extension, and your solicitor will handle this
  • Lease extensions for houses are individual claims – they cannot be combined with collective claims for flats

Final Thoughts

While extending your lease can provide additional security, it’s not always the most advantageous route. The introduction of a modern ground rent means that, in many cases, buying the freehold may be a more attractive long-term option.

If you’re unsure which route is right for you, seeking legal advice early on can help you make the most informed decision.
