Our Lease Extension Calculator is based on the formula in the Leasehold Reform Housing and Urban Development Act 1993 (as amended) and provides an estimated premium for a leaseholder based on 90 additional years.
The actual calculation used by Leasehold Valuation Tribunals is more complicated and subjective than the one used in any online Lease Extension Calculators including ours. For a more accurate and argued valuation you will need to get a proper valuation from a Surveyor. For a quote for a formal Leasehold Extension Valuation Report that can be presented to your Landlord/Freeholder, call Fridaysmove on 0330 660 0287 .
We advise anyone undertaking a Lease Extension to take professional advice. The estimated Premium is a guide only and should not be relied on in any negotiation or discussions.
