Top 50 employers by reported headcount

Methodology & provenance

How this league is ranked

The league ranks the companies in the United Kingdom national register with the highest exact employee counts, as represented in the multi-country company index and refreshed on a rolling cache. Only companies reporting a headcount of at least one can rank — 96.5% of the register reports one — and nothing is estimated for the rest. Headcounts belong to registered legal entities, not corporate groups.
