Lease extension & enfranchisement

What's it really cost to extend your lease?

A short lease costs you more than you think — in value, and in mortgageability. Get an instant estimate, then talk to a specialist.

Estimate your premium

This is an indicative estimate only, built from simplified assumptions — it is not a formal valuation and does not reflect your specific lease terms or the relativity graphs a RICS valuer would use. Under 80 years remaining, marriage value applies and premiums rise sharply.

Your options

Three ways to extend your rights

Lease extension

Add 90 years to your lease and reduce ground rent to a peppercorn. The most common route for flat owners.

Collective enfranchisement

Join with other leaseholders in your building to buy the freehold outright. More complex, often better long-term value.

Right to manage

Take over management of the building without buying the freehold — a lighter-touch alternative.
