TL;DR: The register of licensed sponsors: workers is the official Home Office list of organisations approved to sponsor migrants under the Worker and Temporary Worker routes. It is updated regularly and is a key reference point for applicants and compliance checks alike.
Introduction
The register of licensed sponsors: workers is one of the most consulted documents in the UK immigration system, providing a live, publicly accessible record of every organisation authorised to sponsor foreign nationals on the Worker and Temporary Worker routes. Published and maintained by the Home Office, the register is updated on a rolling basis to reflect newly granted licences, licence suspensions, downgrades and revocations. For anyone assessing a job offer that depends on sponsorship, or for employers seeking to confirm their own standing, the register of licensed sponsors serves as the definitive source of truth.
Unlike a one-off policy announcement, this is an evergreen operational tool rather than a single news event. It sits at the intersection of sponsor compliance and applicant due diligence, and its accuracy has direct consequences for visa applications, sponsor licence audits, and Home Office enforcement activity. This article examines what the register contains, how it functions within the sponsorship system, and what its existence means for both sponsors and applicants navigating the Worker and Temporary Worker routes.
What is the Register of Licensed Sponsors?
The register of licensed sponsors is a publicly available list published by the Home Office naming every UK organisation currently holding a valid sponsor licence under the Worker or Temporary Worker immigration routes. It shows the sponsor’s name, the type of licence held (such as Skilled Worker, Global Business Mobility, or Temporary Worker sub-categories), and its current sponsor rating, typically ‘A’ or ‘B’. The register is refreshed regularly, meaning entries can be added, updated or removed as licensing decisions are made.
How the Register of Licensed Sponsors Operates
Structure and Content of the List
The register is organised alphabetically by organisation name and details the specific route or routes each sponsor is licensed under. According to the published guidance, sponsors may hold licences across multiple categories simultaneously, for example a single employer might be authorised for both the Skilled Worker route and a Temporary Worker sub-category such as Government Authorised Exchange. The register also distinguishes between sponsor ratings, with an ‘A’ rating denoting full compliance with sponsor duties and a ‘B’ rating indicating that a sponsor is subject to an improvement action plan following identified shortcomings.
The register of licensed sponsors: workers is updated periodically, and organisations can be added or removed between publication cycles as Home Office decisions take effect.
Removal and Addition of Sponsors
Organisations are added to the register once their sponsor licence application has been approved following a Home Office compliance visit or paper-based assessment. Conversely, sponsors are removed when a licence is revoked, surrendered voluntarily, or allowed to lapse without renewal. Revocation can follow serious breaches of sponsor duties, including failure to report changes in a worker’s circumstances, employing individuals without the right to work, or failing to keep accurate records. Once removed, any worker sponsored by that organisation typically has their permission curtailed, prompting a defined period in which alternative sponsorship or a new application must be sought.
Why Does the Register Matter for Due Diligence?
The register functions as a critical due diligence tool. Because sponsorship is central to eligibility under both the Worker and Temporary Worker routes, an applicant relying on a certificate of sponsorship from an organisation not listed on the register — or listed with a revoked status — faces immediate risk to their application. The Home Office states that only licensed sponsors can issue valid certificates of sponsorship, meaning verification against the published register is a necessary step in confirming that a job offer is genuine and immigration-compliant.
Compliance Monitoring and Sponsor Duties
The existence of a continuously updated register underpins the broader system of sponsor compliance. Licensed organisations are subject to ongoing duties, including record-keeping, reporting obligations via the Sponsorship Management System, and cooperation with unannounced compliance visits. The register reflects the outcome of this monitoring in near real time: a downgrade from an ‘A’ to a ‘B’ rating, for instance, signals that the Home Office has identified deficiencies requiring correction within a specified timeframe, after which further non-compliance can result in suspension or revocation.
Implications for Sponsors and Employers
For UK employers holding a sponsor licence, appearing correctly on the register of licensed sponsors is essential to maintaining recruitment pipelines involving overseas talent. Sponsors are expected to notify the Home Office promptly of any relevant changes affecting their licence, and lapses in reporting can affect their listed status. Employers considering applying for a sponsor licence should note that only organisations appearing on the register are permitted to assign certificates of sponsorship, meaning inclusion is a prerequisite for lawful sponsorship activity. Employers already holding a licence are advised, according to Home Office guidance, to periodically check their own entry to confirm accuracy, particularly following a compliance visit or organisational restructuring such as a change of trading name or company registration.
Frequently Asked Questions
Q: What is the register of licensed sponsors used for? A: The register allows applicants, employers and third parties to verify whether an organisation holds a valid sponsor licence under the Worker or Temporary Worker routes before relying on a job offer or certificate of sponsorship.
Q: How often is the register of licensed sponsors updated? A: The Home Office updates the register on a rolling basis, with organisations added, removed or having their rating changed as licensing decisions take effect, rather than on a fixed periodic schedule.
Q: What does it mean if a sponsor has a ‘B’ rating on the register? A: A ‘B’ rating indicates the sponsor has been found non-compliant with certain duties and is operating under an improvement action plan set by the Home Office, with a defined period to address the issues identified.
Q: What happens to a sponsored worker if their employer is removed from the register? A: If a sponsor’s licence is revoked and the organisation is removed from the register, affected workers typically have their permission to stay curtailed and are given a limited period to find alternative sponsorship or leave the UK.
Q: Can an organisation appeal removal from the register of licensed sponsors? A: Sponsors facing licence revocation may, depending on the circumstances, have limited routes to challenge the decision through administrative review or judicial review, though the register itself simply reflects the current licensing status determined by the Home Office.
Key Takeaways
- The register of licensed sponsors: workers lists all organisations authorised to sponsor migrants under the Worker and Temporary Worker routes.
- Entries include the sponsor’s name, licensed route, and current compliance rating, either ‘A’ or ‘B’.
- The register is updated on a rolling basis, reflecting new approvals, downgrades, and revocations as they occur.

Conclusion
The register of licensed sponsors: workers remains a cornerstone reference document within the UK’s points-based immigration system, offering transparency around which organisations are authorised to sponsor migrant workers. Its continuous updates reflect the Home Office’s ongoing compliance monitoring, making it an essential checkpoint for applicants verifying job offers and for sponsors confirming their own standing. As sponsorship obligations continue to underpin both the Worker and Temporary Worker routes, the register’s role in supporting lawful, verifiable recruitment is unlikely to diminish.
