Signal exists because the most valuable moment in office-change BD — the months before a company decides — was sitting in plain sight, scattered across lease registers, planning portals and company filings that nobody had joined up.
Every office move leaves a paper trail before it happens. A lease clock ticking at HM Land Registry. A planning application filed with the borough. A hiring surge that doesn’t fit the floor plate. Individually, each is a hint; joined and scored, they’re a forecast.
Signal was built by Liam Kurt Smith in London to do exactly that joining — first for one fit-out sales team drowning in cold lists, now as a platform tracking 155,131 London companies and scoring every one of them, weekly, for how close their next office decision is.
The numbers it produces are public: the London Office Movement Index and the statistics page publish the market-level view, free to cite. The company-level view — who, why, when, and who to call — is the product.
Registered leases — start dates, terms, and the expiry/break clocks that force office decisions.
Filings, accounts, incorporation data, ownership (PSC) changes, headcount indicators — and the risk signals: overdue filings, strike-offs.
Planning applications on occupied offices — the loudest near-term signal of works.
Energy ratings and floor areas — density arithmetic and MEES-driven upgrade pressure.
Insolvency and winding-up notices — so clients stop chasing companies in trouble.
Job postings, headcount trajectories and press — the growth side of the space equation.
Every tracked company gets a 0–100 score built from the strength, recency and — critically — the combination of its signals. A lease expiry alone might mean renewal; a lease expiry plus sustained hiring plus density pressure is a company that has already started deciding. The score measures how strong the evidence is; a separate move window — anchored on lease events and market intelligence — says when they'll go to market. Lists are ordered by the window, because the highest score isn't always this morning's call.
Scores re-run weekly across the whole universe. Relocation and refurbishment are scored separately, because “about to move” and “about to spend on the space they have” are different customers for our clients. Every published figure on this site rebuilds from the live database after each scoring run.
Public record first. The movement intelligence comes from official public sources — HM Land Registry, Companies House, planning registers, the EPC register, The Gazette. Where we read the open web, our identified SignalBot visits public company pages only — robots.txt obeyed, rate-limited, opt-outs honoured (see /bot) — and never collects personal data. We don’t access private platforms and we don’t buy “intent” surveillance.
Contacts are compliant. Decision-maker details come from established B2B data providers under a legitimate-interest basis, and are attached only to companies showing genuine market signals — not blasted as a directory.
Companies, not people. We profile organisations’ property events, not individuals. The unit of intelligence is a lease, a filing, a building — never someone’s personal life.
Citable and correctable. Our public statistics carry their computation date and methodology. If you believe a published figure is wrong, tell us — hello@officemovesignals.com — and we’ll check it against the record.
