Companies leak their next office move long before an announcement: a lease break approaching, planning consent on their building, statutory accounts showing lease commitments running down, a hiring surge their floor plate can’t hold. Signal reads those events across the London market and turns them into a ranked shortlist — who, why, and roughly when.
When a move is in the press, the fit-out is often appointed and the furniture shortlisted. The sales window sits 6–18 months earlier, in the public record.
Companies House address changes often trail the physical move — and the registered office frequently isn’t where anyone works. Operational premises need verifying against rates, leases and EPCs.
A lease expiry alone chases companies that will renew. Real intent shows as corroboration — timing evidence plus growth plus premises facts, on the same company.
HM Land Registry lease events, Companies House filings, local-authority planning, hiring and growth — read continuously across 155,131 London companies.
Every company is ranked 0–100 by how strong, recent and combined its signals are. 60+ is in market; 80+ is imminent. Scores re-run weekly.
Your dashboard opens on your patch: ranked companies, the why-now in one line, timing window, and a decision-maker to call.
Lease expiry, break clause, pre-let, under offer, requirement, dilapidations — the shortlist speaks the market’s language and cites its sources.
