Lease Extension Calculator

Under the 1993 Act, leaseholders have the right to extend their lease by 90 years. Use our calculator to estimate the "Statutory Premium" you might pay.

Note on Reforms: The Leasehold and Freehold Reform Act 2024 aims to make extensions cheaper (e.g. abolishing marriage value), but full valuation changes are not yet fully active. This calculator uses the current standard 1993 Act methodology.

Protecting your asset?

Paying for a lease extension increases your property's value. Ensure your Life Insurance covers your mortgage so your family inherits this value, not the debt.
