Sponsor Licence Obligations for Employers

A sponsor licence is a formal permission granted by the UK Home Office that allows an employer to sponsor non‑UK workers under immigration routes such as the Skilled Worker visa. Holding a licence is not a one‑off administrative step; it creates ongoing legal obligations for the employer. Failure to comply can lead to enforcement action by UK Visas and Immigration (UKVI), including licence suspension, downgrade or revocation. This article explains the duties, reporting and record‑keeping requirements, compliance processes, risks, and practical guidance for employers. All information is grounded in authoritative Home Office guidance.

What Is a Sponsor Licence?

A sponsor licence is issued to UK organisations that wish to employ migrant workers whose visas require sponsorship. It is fundamental in the points‑based immigration system, enabling the assignment of Certificates of Sponsorship (CoS) which the migrant worker uses in their visa application. To obtain and maintain this licence, an employer must demonstrate not only eligibility initially but also ongoing compliance with immigration laws and related duties.

1. Core Obligations of a Sponsor Licence Holder

Once a sponsor licence is granted, the employer must comply with several core obligations from the moment the licence is valid until it is surrendered, revoked, or expires.

1.1. Assigning Certificates of Sponsorship (CoS)

Employers may only issue CoS to workers if:

• The job is genuine and suitable for immigration sponsorship;
• The role meets the eligibility criteria, including skill and salary thresholds under the relevant visa category; and
• All documentation and job details are accurate and valid.

CoS should reflect the actual duties of the role and be issued in the Home Office's Sponsorship Management System (SMS). Misuse-such as issuing CoS for fabricated roles-can constitute non‑compliance with immigration rules.

1.2. Monitoring and Reporting Sponsored Workers

Sponsors must monitor the employment and immigration status of all sponsored workers. This includes:

• Tracking attendance and reporting prolonged unauthorised absences;
• Updating UKVI in the SMS when a worker's role, salary, location, or end of employment changes;
• Notifying UKVI promptly if a sponsored worker stops complying with visa conditions.

Most worker‑related changes must be reported within 10 working days of the event.

1.3. Record‑Keeping Responsibilities

Employers are required to maintain accurate and retrievable records for each sponsored worker. Records typically include:

• Right‑to‑work documentation;
• Job descriptions, employment contracts and payroll records;
• Evidence of skills, qualifications and contact details;
• Immigration status documents and SMS correspondence.

Records are essential for Home Office compliance visits and audits and help demonstrate lawful employment practices.

1.4. Right‑to‑Work Checks

Before employing anyone (sponsored or non‑sponsored), employers must conduct and document right‑to‑work checks in accordance with UK law. Evidence of these checks must be retained and provided to UKVI on request.

2. Reporting Changes and Time Limits

Sponsors have explicit reporting duties to notify UKVI of changes affecting either the worker or the organisation itself.

2.1. Worker‑Related Changes

Key changes include:

• Job role changes or significant change in duties;
• Salary adjustments;
• Absence or termination of employment;
• Changes to the worker's contact details or immigration status.

These must normally be reported within 10 working days.

2.2. Organisational Changes

Changes in the employer's circumstances must be reported within 20 working days. This includes:

• Business closure or insolvency;
• Mergers, takeovers or substantial restructuring;
• Changes in registered business address or HR systems;
• Modifications to contractual relationships with overseas partners.

These timely notifications help ensure the validity and appropriateness of the sponsorship arrangement.

3. Key Personnel and Internal Systems

A sponsor licence holder must appoint specific staff roles with responsibility for compliance:

• Authorising Officer: Senior individual responsible for overall compliance;
• Key Contact: The main liaison with the Home Office;
• Level 1 User: Day‑to‑day manager of the SMS;
• Level 2 User: Optional support user.

These personnel must be based in the UK, free from serious unspent convictions, and capable of fulfilling their functions. Employers must ensure continuity by replacing personnel when they leave or are unavailable.

4. Compliance Visits, Audits and Enforcement

The Home Office may conduct compliance visits at any time during the validity of a sponsor licence. These visits review HR systems, records, right‑to‑work checks and evidence that roles and duties correspond accurately to the records held in the SMS. Audits may be announced or unannounced.

4.1. Consequences of Non‑Compliance

Failure to comply with sponsor duties can result in a range of sanctions, including:

• Downgrade of licence rating and curtailment of sponsorship rights;
• Suspension of the sponsor licence, preventing new CoS assignments;
• Revocation of the licence, potentially invalidating current sponsored workers' leave;
• Reporting to law enforcement if evidence of criminal activity arises.

Sanctions may also include action plans or financial costs associated with restoring compliance.

5. Wider Legal and Ethical Obligations

In addition to immigration‑specific duties, sponsors must comply with broader UK law, including:

• Employment law obligations such as the National Minimum Wage, working time regulations and workplace rights;
• Anti‑discrimination and health and safety laws;
• Obligations not to engage in conduct “not conducive to the public good,” which could affect licence status.

These duties reflect the Home Office's interest in preventing exploitation, protecting worker rights, and ensuring that sponsorship is exercised by genuine, law‑abiding organisations.

6. Practical Steps for Compliance

Employers should adopt clear internal procedures and systems to meet their sponsor licence obligations. Best practice includes:

• Maintaining a centralised record‑keeping system;
• Regular training for HR and staff involved in sponsorship duties;
• Internal audits of SMS activity and right‑to‑work checks;
• Prompt reporting of any changes within the required deadlines;
• Ensuring job descriptions and contracts align closely with CoS details.

7. Common Questions and Clarifications

Can an employer charge a worker for sponsorship costs?
No. From 1 January 2025, recouping licence or Certificate of Sponsorship costs from the worker is prohibited and can lead to licence revocation.

What happens if key personnel leave the business?
An employer must appoint replacement key personnel to maintain compliance. Failure to do so can undermine licence validity.

Does compliance stop when a licence expires?
No. Sponsors remain responsible for their duties until the licence is formally surrendered, revoked, or expired, and often beyond for post‑employment record‑keeping.

Summary

Holding a sponsor licence is a legally significant commitment for employers that extends well beyond initial approval. Employers must assign Certificates of Sponsorship responsibly, maintain accurate records, conduct right‑to‑work checks, report changes in worker or organisational circumstances within prescribed deadlines, and be prepared for compliance visits. Failure to adhere to these obligations can result in serious consequences, including licence revocation, operational disruption and reputational harm. Proper HR systems, trained personnel and robust internal procedures are essential to manage sponsor duties effectively.
