Who Needs a Certificate of Sponsorship?

You’ll need a CoS for any overseas hire applying under the Skilled Worker route, whether they are coming from abroad or switching from within the UK. The vacancy must meet eligibility criteria including minimum salary thresholds and skill level (typically RQF Level 6 or higher).

Recent Changes

Since the end of free movement between the UK and EU, all EU nationals (except those with settled or pre-settled status) also require sponsorship to work in the UK under a Skilled Worker Visa.
