Notes and limits
- 1-year headcount growth from licensed B2B firmographic and technographic data. Companies with 10–1,000 staff that grew 20%+ in a year. UK file: every company growing 50%+ is included; in the +20–50% band the largest companies are kept (21+ staff).
- Growth is shown as a band: +20–50%, +50–100%, +100–200% or 200%+ (estimated). Within a band, companies are listed largest first; the order inside a band is not a growth ranking.
- "200%+ (estimated)" means the growth figure is above 200% and has not been verified; treat it as an estimate.
- Likely branches of larger groups, schools, academy trusts, colleges and university units are left out.
- Growth is a signal, not a guarantee of open roles or budget.
- Company-level data only: no personal contacts.
