Statistics are derived from LeaseIntel's tribunal database of 2,349 analysed First-tier Tribunal (Property Chamber) lease extension decisions (2005–2025). Headline £ figures use the 1,009 decisions with a determined premium. Exceptional outlier cases and specialist lease structures may be excluded from certain summary measures where appropriate.
Representative First-tier Tribunal lease extension decisions selected from the LeaseIntel database to illustrate different valuation scenarios encountered in practice.
Over 111 years remaining, so no marriage value — yet an onerous escalating ground rent drove a significant premium, with the capitalisation rate the sole dispute.
Read Official Tribunal Decision →Just below 80 years, but the Section 42 notice was served above the threshold so no marriage value applied. Tribunal landed between a £30,138 claim and a £9,600 offer.
Read Official Tribunal Decision →Near-expired lease with fewer than five years remaining. Tribunal adopted deferment rates of 5.5% short-term and 5% long-term, accepting the leaseholder's valuation.
Read Official Tribunal Decision →Prime Victorian mansion block near Westminster Cathedral. The freeholder's £451,470 claim was reduced 42.5%, with the demise of a separate WC also resolved for the leaseholder.
Read Official Tribunal Decision →Sole dispute was relativity: Gerald Eve graphs (72%) vs market evidence from the estate (63.93%). Tribunal preferred the market evidence, illustrating its valuation impact.
Read Official Tribunal Decision →Every input agreed except the unencumbered freehold value — a £554,600 gap that translated into a £133,693 swing in the premium. Freehold evidence drove the outcome.
Read Official Tribunal Decision →These featured decisions illustrate how different lease lengths, property values, ground rent structures and valuation assumptions influence tribunal-determined lease extension premiums.
Recurring themes observed across recently analysed tribunal outcomes. For deeper analysis on specific patterns, see our research on lease extension cost by years remaining, premiums below 80 years and the London borough analysis. To put your own figure in context, you can benchmark your quote against comparable cases.
Tribunal outcomes consistently show that as the unexpired term reduces, premiums rise non-linearly — with the steepest movement around the 80-year threshold.
Where leases fall below 80 years, marriage value is a frequent point of contention, with relativity assumptions driving much of the gap between parties.
Tribunals continue to scrutinise ground rent capitalisation, especially where rent review clauses or doubling provisions affect the freeholder's interest.
Premiums vary significantly between prime central London and outer boroughs, reflecting underlying values and the comparable evidence each tribunal weighs.
Many cases settle close to the midpoint of the parties' valuations — reinforcing the value of benchmarking quotes against comparable tribunal outcomes early.
Two-bedroom flat, prime central London, 76 years unexpired
Tribunal determined a premium materially below the freeholder's opening position but above the leaseholder's offer, after rejecting both parties' relativity evidence and substituting its own.
Illustrates how tribunals routinely depart from both parties' valuations when comparable evidence is weak — and why a benchmark grounded in actual decisions is more reliable than either side's opening figure.
Opening offers — from freeholders or leaseholders — are rarely a good predictor of tribunal outcomes. Comparable decisions are.
