Notes and limits
- Licensed to sponsor does not mean hiring now. A sponsor licence means the employer can sponsor some roles; check each advert and the salary threshold for your occupation code.
- Joined by normalised company name plus town to the UK Home Office Register of Worker and Temporary Worker licensed sponsors (9 October 2026). 547 of 4005 fast-growing UK companies matched (14%); trading names that differ from the legal name will not match.
- Contains public sector information licensed under the Open Government Licence v3.0.
- Growth = 1-year change in headcount from licensed B2B firmographic and technographic data.
- 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.
- Schools, academy trusts, colleges and university units are left out, as are likely branches of larger groups.
- Company-level data only: no names, emails or phone numbers of people.
