Answers · London office market · 1 October 2026
Ten public-record signals precede an office move, fit-out or refurbishment: a lease heading for expiry, a break clause window opening, a planning application on their building, sustained office-based hiring, headcount outgrowing the floor plate, an ownership change, a funding round, maturing inside serviced or flex space, a poor EPC on the building, and accounts or filings turning late (a risk signal, read in reverse). The full field guide, with how early each shows and where to find it, is on its own page.

The longer answer
The earliest and most reliable sign is the lease: a registered lease heading for expiry shows 12–24 months out and a break clause window 9–18 months out; both force a decision and both are public at HM Land Registry. The building gives the next tier — a planning application for refurbishment, redevelopment or change of use (3–12 months out) displaces every occupier, and a poor EPC against the coming MEES standard (12–36 months out) pushes the landlord to works. The company gives the rest: sustained hiring for office-based roles (6–18 months), declared headcount that no longer fits the measured floor area (6–24 months), a change of control on the PSC register (6–18 months after), a funding round (3–12 months), and a company maturing inside serviced or flex space and ready for its own lease. Accounts or filings turning late is the one sign to read in reverse — a company in trouble is more likely to shrink than to move. No single sign is enough; Signal scores the combination and the corroboration across independent registers. The field guide explains each sign, how early it shows and the register it comes from.
