Estimate the premium to extend a lease or buy the freehold under the pre-commencement method, then compare a separate 2024 Act scenario. The law is changing: this is not a formal valuation or statement of current entitlement.
🔎 Short-lease finder
Type a postcode and it reads the block's registered leases from the title data — every returned flat, years remaining, shortest first. A recorded term under 80 years is a valuation and lender-check signal, not a guaranteed discount. Uses 1–3 tokens depending on block size; free if nothing is found.
Advanced valuation rates (tap to tune)
Sportelli defaults: 5% deferment, ~7% capitalisation. Real cases vary by tribunal.

Estimate using a term + reversion + marriage-value model and an illustrative 2024 Act scenario. At the official 7 September 2026 review, the relevant valuation changes still required consultation, secondary legislation and commencement. Check the current GOV.UK position and obtain specialist legal and valuation advice before relying on a figure.
