Understanding the Register of Licensed Sponsors in 2026
The UK Home Office updates the Register of Licensed Sponsors daily, providing a public record of all entities authorized to issue Certificates of Sponsorship (CoS) under the Skilled Worker and Temporary Worker routes. For UK HR Directors and Business Managers, checking this register is a non-negotiable step in candidate vetting and supply chain compliance. For visa applicants, verifying a prospective employer's current standing prevents costly visa refusals under Paragraph 9.24.1 of the Immigration Rules.
Licence Ratings and Operational Limitations
Every organization listed on the register holds either an A-rating or a B-rating for specific sponsorship routes. Understanding the practical differences is critical for recruitment planning:
- A-Rating: Confirms full compliance with Home Office duties. Employers can freely allocate Defined Certificates of Sponsorship (DCoS) for overseas applicants and Undefined Certificates of Sponsorship (UCoS) for in-country switches.
- B-Rating: Applied when UKVI compliance officers identify failures during an audit under Sponsor Guidance Part 3. A B-rated sponsor cannot issue new CoS to recruit new workers. They must pay a £1,500 fee for a mandatory Action Plan and resolve all compliance breaches within three months.
Verifying Employer Legitimacy Before CoS Assignment
Before issuing a CoS under SOC 2020 codes such as 2134 (IT Development Managers) or 1139 (Directors in Logistics), HR teams must ensure their entry on the register accurately reflects their legal entity name, trading name, and active branches. Under Appendix D compliance guidelines, any discrepancy between the register entry and Companies House filings can trigger a formal UKVI compliance audit.
Impact of Licence Revocation on Sponsored Workers
If an employer is removed from the Register of Licensed Sponsors due to severe compliance breaches—such as failing to report worker absences within 10 working days or underpaying the statutory £38,700 Skilled Worker salary threshold—active worker visas are immediately impacted. Under Immigration Rules Part 9, affected employees will receive a curtailment notice reducing their leave to 60 days, during which they must secure sponsorship with a new A-rated employer or exit the UK.
Actionable Compliance Checklist for HR Managers
- Cross-reference company details on the public register every quarter against Companies House records.
- Monitor the Sponsor Management System (SMS) for automated notifications regarding licence renewal deadlines and key personnel updates.
- Audit internal right-to-work documentation to ensure compliance with Appendix D retention standards.
