The longer answer
As of 1 October 2026, 256 of the 166,845 London companies Signal tracks score 60 or more on its model — the threshold at which the public record (a lease ending, a planning application on their building, sustained hiring, an ownership change) says a move, fit-out or refurbishment is coming. 17 score 80+ and are moving imminently. The busiest submarket is City & fringe (EC) (97 in market) and the most active sector is Finance & insurance (52). The companies themselves are not named on this site: the named, scored and timed list is what Signal's customers subscribe to. What is public is the weekly pattern — 5 publicly reported occupier events in the week of 28 Sept–4 October 2026, led by finance & insurance and concentrated in West End, each linked to the publisher that reported it — on the London office moves page.
