Lease Enfranchisement Calculator

For leaseholders, one of the biggest concerns is what happens when the lease term gets shorter. A short lease can significantly reduce property value, make it harder to sell, and limit mortgage options.

That’s where lease enfranchisement comes in. Enfranchisement is the legal process that allows leaseholders to either:

• Extend the lease (typically by 90 years for flats in the UK)
• Collectively buy the freehold of the property from the landlord

Since the cost of enfranchisement can be complicated to calculate, the Lease Enfranchisement Calculator is a vital tool. It helps property owners estimate how much they’ll need to pay to secure their lease extension or buy the freehold.

🔎 What Is Lease Enfranchisement?

Lease enfranchisement refers to a leaseholder’s right to:

1. Extend the lease – Add extra years (often 90+) to the existing lease.
2. Buy the freehold – Purchase the land/building ownership collectively with other leaseholders.

The cost of enfranchisement depends on several factors, including:

• Current lease length
• Ground rent payable
• Property value (with and without lease extension)
• Marriage value (the increase in property value after extending)
