Project databases see a scheme once it has a planning reference. Property databases see a building once there’s a deal. Signal reads the occupier’s own record — the lease on its floor, its business rates, its filings, its hiring — across every London office occupier, and hands you twenty companies each Monday with the evidence, the timing and the person to call. Before the design team is appointed. Before it’s a tender.
Figures update weekly · computed 23 September 2026
An office move is the biggest buying moment in your market — and most firms only hear about it once everyone else has too.
The brief lands when it's already a six-way pitch, and you're competing on price instead of relationship.
Right company, wrong week. There's no way to time the call to the moment they're actually deciding.
A database of 165,600 names is coverage, not a call list. Without the trigger that says this one is in market now, it’s noise.
Signal watches 165,600+ London occupiers so you only have to call twenty. Each Monday: twenty companies showing evidence of an office move, fit-out or refurbishment — ranked, with the reason, the timing window, and a decision-maker to ring. No database to trawl. No waiting for the tender.
It's not just relocations. Signal also catches the bigger pool most tools miss — companies refurbishing or reconfiguring the office they're staying in.
Every London office occupier, all the time — the lease registered on its floor, the business rates that put it there, its Companies House filings, its planning applications, its hiring. Fifteen public sources, read continuously, resolved to the right company and the right building.
Each company is scored 0–100 on how strong, recent and corroborated its evidence is. Every claim behind a score carries its source and its date — a lease clock, a rates bill, a filing — so the score is never a black box. Re-run on every new signal and in full every Sunday.
Twenty companies land on Monday — ranked, why now in a line, timing, and the person to call. Pursue pushes it to your CRM with the evidence; not-for-us and not-moving take it off the sheet for good. You arrive while they’re still deciding, not after.

The signals and terms behind every move — and why each one matters for timing the call.
A break clause, expiry or rent review approaching on a company's lease — the single strongest predictor that an office decision is coming, usually 6–18 months out.
A contractual point at which a tenant can exit the lease early. As it nears, companies decide whether to stay, refit or move.
A scheduled reassessment of rent, often upward — a common trigger for a company to reconsider its space.
The cost of returning a leased office to its original condition on exit. A looming dilapidations liability often forces an early move-or-refurb decision.
Cat A is the landlord's base finish (floors, ceilings, services); Cat B is the tenant's fit-out — layout, branding, meeting rooms. Most fit-out, furniture and AV work sits in Cat B.
A single contractor handling both the design and construction of an office fit-out — the dominant delivery model for commercial workplaces.
The RIBA Plan of Work (Stages 0–7) maps a project from strategic definition to handover. Winning work early means being briefed around Stage 0–1.
An agent acting for the company taking space (the occupier), rather than the landlord — the people who find and secure the new office.
A company actively evaluating a move, refit or refurbishment. Signal's job is to surface in-market companies before they go to tender.
The pilot is the call sheet on your own patch for 30 days. If the rows are good, the pilot fee comes off your setup.
Every plan includes a named account owner who sets your ICP and keeps Signal tuned to your market as it changes. Extra seats available on any plan.
Your numbers, not ours — drag the sliders. Signal only has to tip a project or two your way.
