What is a Sponsor Licence, and do you need one?

A sponsor licence empowers employers to issue certificates of sponsorship to skilled workers from outside the UK. A sponsorship licence is crucial for enabling international employees to work legally within your organization.

By enabling UK businesses to recruit skilled workers and workers in areas of identified labour shortage, a sponsor licence allows a business to maintain business continuity when unable to recruit from the resident labour market.

Who needs a sponsor licence?

UK organisations who wish to employ skilled workers from outside the UK or Ireland, who do not possess indefinite leave or pre-settled status under the EU Settlement Scheme, must obtain a sponsor licence. This obligation is consistent across all organisations, irrespective of their size or the number of foreign employees they intend to hire.

The Home Office can fine an employer found to be employing a foreign worker without permission up to £45,000 per employee (£60,000 for repeat breaches).

Types of Sponsorship Licence

There are different types of UK sponsorship licence available:

Apply for a sponsor licence

To obtain a Sponsorship Licence, an employer must complete an on-line application process and submit documents to the Home Office within a strict schedule to demonstrate the company is an active trading entity.

✔️ Login to the sponsor licence application portal and complete the online form.

✔️ Pay the relevant the sponsor licence application fee.

✔️ Submit an Authorising Officer’s declaration with supporting documentation within 5 working days.

The documents to be provided depend on the type of licence applied for, the organisation applying, and the employees (or prospective employees) it would like to sponsor.

The process involves proving the employer’s financial standing, robust HR systems, and your capability to responsibly sponsor international talent.

Amongst other things, employers requesting a Global Business Mobility tier to their licence must prove the common ownership of the companies in question.

It normally takes around six weeks for a Sponsorship Licence to be issued. An expedited service is available which can reduce the processing time to as little as two weeks.

Once granted, Sponsorship Licences are issued for 10 years.

Sponsor Licences granted before 6 April 2024 are automatically renewed for a period of 10 years.

We strongly recommend any company planning on applying for a Sponsorship Licence or sponsoring an employee to take legal advice from an immigration lawyer before doing so.

Documents needed for a sponsor licence

The documents needed for a sponsor licence application can be found listed in “Sponsor guidance appendix A: supporting documents for sponsor applications”.

The appendix provides comprehensive guidance on the necessary documents for UK sponsor licence applications.

Applicants must typically submit a minimum of four separate items of evidence, however, it is usually best to supply further evidence wherever possible.

Exceptions exist for public bodies recognised by the UK Government, such as local authorities or companies listed on the London Stock Exchange that are permitted to produce fewer.

The required documents vary based on your business and the type of licence needed.

Examples of evidence that you might produce for a sponsorship licence include:

  • annual accounts;
  • evidence of a corporate bank account;
  • VAT registration;
  • HMRC registration for PAYE/NI – this must be issued by HMRC with your employer or PAYE reference number
  • and accounts office reference number;
  • employer’s liability insurance certificate (providing a minimum cover of £5 million and issued by a FCA regulated insurer;
  • proof of ownership or lease of business premises – if a lease agreement, it must be signed by all parties; evidence of local authority planning permission or similar for the type or class of business;
  • evidence of any mandatory or non-mandatory registration or accreditation with a professional or accreditation body;
  • proof of registration with HMRC for the payment of Corporation Tax , e.g. Company Tax Return (CT620), or the completed CT600 tax return and CT603 notice;
  • contracts for goods or services; franchise agreement;
  • premises licences; and
  • organisational charts.

This list is illustrative and not exhaustive. Ensure you understand the sponsor licence application process and seek specialist advice.

Genuine vacancy requirement

UK employers applying for a sponsor licence must demonstrate a genuine need to recruit overseas talent. The process involves passing the genuineness test, which confirms the business has a genuine vacancy, in a role that is eligible for sponsorship while meeting specific skill and salary criteria.

The Home Office may conduct a sponsor licence check to ensure the role aligns with the business’ nature and requirements. Meeting the genuineness test is crucial both during the application process and throughout the duration of the sponsor licence.

Employers should outline the roles they seek to fill and details of prospective candidates, if identified. While not mandatory, providing comprehensive recruitment details can enhance the application.

What if the sponsor licence application is refused?

A sponsor licence may be refused for various reasons, including:

  • sending incorrect or inadequate evidence;
  • not responding to a request from the Home Office within the strict time deadlines;
  • doubts about the authenticity of the application or whether the vacancy is genuine; or
  • providing inaccurate or false information.

If your sponsorship licence application is refused, you may be subject to a cooling-off period before you can reapply, depending on the reason for refusal.

Questions clients ask

Before you book, the questions we hear most.

Anything else, just ask us.

What types of job can I sponsor employees for?

The Home Office maintains three lists of job types that can be sponsored:

NQF level 6 jobs (degree level roles);
Immigration Salary List (shortage occupations that may be below NQF6); and
Temporary Shortage List (a transitional list of shortage occupations that may be below NQF6).

Can my solicitor hold any of the key licence roles?

It depends on the circumstances.

If you are applying for your licence, your Authorising Officer and Level 1 User MUST be existing employees of your business.

Once you have a sponsorship licence, you can appoint your solicitor to the Level 1 or Level 2 role, provided you always have at least 1 Level 1 User that is your employee.

What are Certificates of Sponsorship?

A Certificate of Sponsorship (CoS) is akin to a work permit. An employee will require a CoS to apply for a visa to enter or stay in the UK as a Skilled Worker.

Undefined CoS

Employers are granted undefined CoS (which can be used to sponsor an in-country worker) through an annual limit based on the number of certificates granted in the previous year, although additional CoS can be requested either as part of the annual allocation or by requesting an in-year increase to the allocation.

Please note when applying for additional increase for undefined Certificates of Sponsorship, the processing time for such requests is up to 18 weeks, although for an additional fee of £200 a licence holder can request to prioritise the request.

Defined CoS

Employers can request 'Defined' Certificates of Sponsorship for out of country applicants.

What documents are required?

Applicants typically provide at least four supporting documents. Examples include annual accounts, HMRC registrations, employer liability insurance, proof of premises, VAT registration and corporate bank statements. The exact documents depend on the licence type and business structure.

What happens if the application is refused?

Refusals may occur due to insufficient documentation, missed deadlines, concerns about a genuine vacancy or inaccurate information. A cooling-off period may apply before reapplication.
