Methodology
Sources. Buildings where HM Land Registry registered leases held by tracked London companies end in the year. One company, one expiry; the demise (floor/suite) is stripped to the building. Floor area is the largest VOA rating-list or EPC area recorded for an expiring occupier at the building. Expiries known only from private sources are excluded from this list, so year totals here are lower than the district totals above.
Counting. Future lease expiry dates held against London companies (HM Land Registry registered leases, statutory accounts disclosures, and lease records on file), aggregated by postcode district and calendar quarter. Cells under 3 companies are suppressed. The year total above (75) counts every source; the building list (59) counts registered leases only, because only a register entry places a lease at a building with certainty.
