Any estimate produced by this calculator is for initial guidance purposes only.

It must not be used for any other purpose. It does not take into account all of the variables that can alter the price of a lease extension. It does not allow for the effects of high ground rents or aggressive accelerators. It does not allow for high value ‘short’ lease flats and the possible variables applicable to them. All lease extension prices are subject to negotiation.

Specific assumptions apply when determining the existing lease value of a flat and inaccuracy can significantly affect the end lease extension price. The calculation produced must not be relied upon to serve a statutory Notice nor should it be used as evidence in cases being heard at the First-tier Tribunal (Property Chamber) or the Upper Tribunal (Lands Chamber).

The lease extension process must not commence without seeking prior formal professional advice from a specialist valuer (and a specialist solicitor). If you or any of your clients wish to take action to extend a lease or purchase a freehold, then please contact us on +44 (0) 20 8688 8984 or email:
