The timeline
Expiries by quarter
Every tracked London office lease expiry over the next six quarters. Decisions start 9–18 months before these dates — the buying window for fit-out, relocation and workplace services opens well before the expiry lands.

Methodology
Where this data comes from
Sources. Lease expiry dates held against named London companies: registered leases at HM Land Registry, lease-commitment maturity disclosures in statutory accounts filed at Companies House, and lease records on file. Each date is attached to the occupying company, not just the building — see data sources.
Counting. One company, one expiry (its nearest future one). Aggregated by postcode district of the company’s operational address and calendar quarter. Cells with fewer than 3 companies are suppressed (shown as ·) but still count toward totals. Registered-lease coverage is a floor, not a ceiling: many renewals never reach the register, so true expiry volumes are higher.
Freshness. Rebuilt weekly. This page’s figures were generated on 1 October 2026. The underlying JSON is freely downloadable — cite with a link.
These are counts. Signal sells the names.
Behind every number on this page is a named company with a scored, timed reason to move. If your business wins work when companies change office, see the leads themselves.
