Sponsor Licence FAQs for Employers: Clear Answers from Specialist Lawyers

Employers across the UK are increasingly turning to overseas talent to fill skill shortages and strengthen their workforce. To do this legally, a business must hold a valid sponsor licence issued by the Home Office. For many employers, the rules and requirements around sponsorship can seem complex and overwhelming.

To help, we have prepared this in-depth FAQ guide. Drawing on the expertise of specialist immigration lawyers, it answers the most common questions employers ask about sponsor licences. From who needs one to how long it lasts, here are the clear answers you need.

What is a sponsor licence and who needs one?

A sponsor licence is an official authorisation from the Home Office that allows UK businesses to engage non-UK and non-settled workers in certain visa categories, such as the Skilled Worker route. Without this licence, it is unlawful to hire overseas nationals who do not otherwise have permission to work in the UK.

Any business, from small start-ups to large corporations, that wishes to recruit international staff must apply for and hold a sponsor licence. This requirement applies whether you intend to fill a single vacancy or create an entire team of sponsored workers.

How long does a sponsor licence last?

As of April 2024, most sponsor licences no longer have an expiry date. Once granted, a licence remains valid indefinitely unless the business surrenders it or the Home Office revokes it due to non-compliance.

There are some exceptions. Licences under the UK Expansion Worker route and the Scale-up route remain time-limited and usually last for four years. Employers using these categories should plan ahead for renewal or transition.

Can small businesses apply for a sponsor licence?

Yes. A sponsor licence is not limited to large companies or multinational organisations. Small and medium-sized businesses are eligible to apply as long as they can demonstrate that they meet the Home Office requirements.

This includes showing that the business is actively trading in the UK, has suitable HR systems in place to monitor sponsored workers, and can comply with reporting and record-keeping obligations. Many SMEs successfully hold licences and rely on them to recruit international specialists when domestic recruitment is insufficient.

What are the primary conditions for obtaining a licence?

To secure a sponsor licence, employers must demonstrate that they are a genuine and trustworthy organisation capable of meeting the Home Office’s compliance standards. Key requirements include:

• Genuine business presence: The company must be actively trading in the UK.
• HR systems: Processes must exist to monitor sponsored workers, keep records, and report relevant changes.
• Suitable roles: Jobs offered must meet the visa route requirements, including appropriate skill level and salary thresholds.
• Key personnel: The business must nominate individuals to act as Authorising Officer, Key Contact, and Level 1 User to manage the licence.

Meeting these conditions helps reassure the Home Office that the business will uphold its sponsorship duties.

How much does it cost to apply?

The application expense for a sponsor licence varies based on the size of your business and the visa routes you wish to sponsor under. For most employers, the main costs are:

• Small or charitable sponsors: £574
• Medium or large sponsors: £1,579

There may be additional costs for assigning Certificates of Sponsorship (CoS) to workers. Employers should also budget for the Immigration Skills Charge, which is payable when sponsoring certain workers and can be a significant ongoing cost.

What documents are required for the application?

The Home Office requires employers to submit supporting documents to prove their eligibility. While the exact list depends on the nature of your business, typical documents include:

• Evidence of registration with HMRC.
• Latest corporate bank statements.
• Proof of trading premises, such as a lease or utility bill.
• Audited accounts or annual reports.
• Relevant registrations (for example, with professional bodies if required in your industry).

Providing complete and accurate documentation is crucial. Missing or inconsistent evidence is one of the most common reasons for sponsor licence applications being refused.

What are the duties of a sponsor licence holder?

Maintaining a sponsor licence comes with ongoing obligations. Employers must comply with strict duties, including:

• Record-keeping: Keeping copies of workers’ passports, visas, and right-to-work checks.
• Monitoring: Tracking sponsored workers’ attendance and reporting unauthorised absences.
• Reporting: Notifying the Home Office of changes such as promotions, job title changes, or early terminations within set timeframes.
• Compliance: Ensuring that sponsored roles continue to meet skill and salary requirements.

Failure to meet these duties can put the licence at risk and may result in penalties.

What happens if a business fails to comply with sponsor duties?

Non-compliance can have serious consequences. The Home Office carries out audits and compliance visits to check that employers are meeting their obligations. If issues are found, the Home Office may:

• Issue warnings or downgrade the licence rating.
• Suspend the licence while investigations take place.
• Revoke the licence entirely, meaning sponsored workers lose their right to work.
• Impose financial penalties for illegal working.

For employers, the reputational damage and operational disruption can be significant. Maintaining robust HR systems is the best defence.

Can a sponsor licence be revoked or suspended?

Yes. The Home Office has the power to suspend or revoke a licence if a business is found to be in violating its obligations. Common reasons include employing workers in roles that do not meet visa criteria, failing to carry out right-to-work checks, or providing false information.

If a licence is suspended, the employer cannot issue new Certificates of Sponsorship until the issues are resolved. If revoked, all sponsored workers may have their visas curtailed, forcing them to leave their employment and, in some cases, the UK.

How do employers renew their sponsor licence?

For most employers, renewal is no longer necessary. Licences granted from April 2024 onwards remain valid without an expiry date. However, businesses must continue to comply with all duties, as the Home Office can revoke the licence at any time for breaches.

For categories that remain time-limited, such as UK Expansion Worker licences, employers should apply for renewal before the end of the four-year validity period. Careful planning is essential to avoid gaps in sponsorship rights.

How long does the application process take?

The Home Office generally aims to decide sponsor licence applications within about eight weeks. Processing times, however, are not fixed and may be longer if the case is complex or if the Home Office is experiencing a high volume of applications.

There is also a priority service available for an extra fee, which aims to provide a determination within 10 working days. Demand for this service is high, so places are limited and must be booked quickly once your application is ready.
