What Is a UK Sponsor Licence?

A UK Sponsor Licence is permission from the Home Office that allows a UK-based business or organisation to legally hire skilled workers from outside the UK. If your business wants to bring in talent from overseas, whether for a long-term role or temporary position, you'll need this licence.

It essentially gives you the authority to act as a sponsor under the UK's immigration system. Once you have the licence, you can issue Certificates of Sponsorship (CoS) to eligible foreign workers so that they can apply for a UK work visa, such as the Skilled Worker visa.

A Sponsor Licence confirms that your organisation is genuine, actively trading in the UK, and capable of meeting its responsibilities under UK immigration law.

Why Supporting Documents Are Required for a Sponsor Licence

The Home Office requires you to submit several documents to confirm that your business is genuine, legally operating, and capable of meeting its sponsorship responsibilities.

When you apply for a UK Sponsor Licence, you must prove that your business:

  • Is genuine and legally operating in the UK
  • Has a credible need for sponsoring migrant workers
  • Is capable of complying with sponsor duties
  • Meets the specific requirements for the visa routes you're applying for, such as the Skilled Worker route

To do this, you'll need to submit supporting documents with your application, usually at least four documents, depending on your business type.

How Many Documents Do I Need to Submit for a Sponsor Licence Application?

In most cases, you'll need to submit at least four supporting documents with your UK Sponsor Licence application. These documents must prove your business is genuine, legally trading in the UK, and capable of meeting sponsorship duties.

However, the exact number and type of documents may vary depending on your business type, industry, and the visa route you're applying under.

What Documents Are Required for a Sponsor Licence Application?

When applying for a Sponsor Licence in the UK, you'll need to provide several supporting documents to prove your business is genuine, legally operating, and capable of fulfilling sponsorship duties.

You will need to provide:

  1. Business bank statements (recent)
  2. VAT registration certificate (if applicable)
  3. HMRC registration (PAYE and Accounts Office reference)
  4. Certificate of incorporation (for limited companies)
  5. Evidence of business premises (lease, ownership, or utility bills)
  6. Latest audited or unaudited accounts
  7. Employer's liability insurance (minimum £5 million cover)
  8. Professional indemnity insurance (if applicable)
  9. Company hierarchy or organisational chart
  10. Signed and dated submission sheet (from online application)
  11. HR policy & procedure documents
  12. HR system to track sponsored workers' right to work and absences.

Additional documents might be needed based on your business type and the Skilled Worker route you're applying under.

Proof Your Business Is Legitimate and Actively Trading

When applying for a UK Sponsor Licence, you'll need to show that your business is genuine, legally registered, and currently operating. The Home Office uses these documents to verify your trading status and financial activity.

Here's what you'll typically need:

  • Business bank statements (recent, showing transactions)
  • HMRC registration (PAYE & Accounts Office references)
  • VAT registration certificate (if applicable)
  • Proof of business premises (lease, rental, or ownership docs)
  • Latest audited or unaudited financial accounts

These documents demonstrate that your business is legitimate, financially active, and has a physical UK presence, key requirements for a successful Sponsor Licence application.

Insurance Documents Needed for Sponsor Licence

When applying for a UK Sponsor Licence, one key document you must include is a valid Employer's Liability Insurance certificate with at least £5 million cover. This proves your business meets UK legal requirements and can cover employee-related risks.

To meet Home Office expectations, your certificate must show:

  • Minimum cover of £5 million
  • Valid and up-to-date policy
  • Issued by an authorised UK insurer

Employer's Liability Insurance is legally required for most UK employers and forms an essential part of your Sponsor Licence application. Without it, your application could be rejected.

HR & Compliance Documents Required for Sponsor Licence

You'll need to provide HR policy documents to prove you can handle sponsor duties and stay compliant with UK immigration regulations.

As part of your Sponsor Licence application, you'll need to show that your business has a reliable HR system to track and manage sponsored workers effectively.

Key HR and compliance documents include:

  • HR policies and procedures: Showing how you manage sponsored workers and report changes
  • Absence tracking systems: Evidence that you can monitor staff attendance
  • Right to work check processes: Proving your business carries out legal checks before hiring
  • Recruitment records or sample employment contracts: showing how you hire and manage employees

HR & compliance documents help demonstrate that your business is organised, compliant, and ready to meet its sponsorship duties.

Mandatory Documents for Certain Organisations

When applying for a UK Sponsor Licence, some businesses must provide specific mandatory documents based on their industry type, structure, or the visa route they're applying for.

For example:

  • Regulated industries (like healthcare or education) may need proof of registration with relevant bodies (e.g. CQC, Ofsted).
  • Startups or franchises might be asked for extra evidence to confirm trading activity or structure.
  • If applying under a specific visa route (like the Skilled Worker route), extra documents may be needed to support the job roles offered.

These documents help the Home Office confirm that your organisation is eligible, legitimate, and properly regulated where necessary. Always check which documents apply to your specific business type before submitting your Sponsor Licence application.

Mandatory Documents for Specific Routes

When applying for a UK Sponsor Licence, the documents you need can vary depending on the visa route you're applying for, such as the Skilled Worker, Senior or Specialist Worker, or UK Expansion Worker route.

Each route has specific requirements to prove your business is suitable to sponsor workers under that category.

For example:

  • Skilled Worker route: You may need to provide detailed job descriptions, salary information, and proof that the roles meet the skill and salary thresholds.
  • UK Expansion Worker route: Requires evidence of your overseas business and proof of establishing a UK footprint (like a UK business address).
  • Senior or Specialist Worker (Global Business Mobility): You may need group structure charts or documentation linking your UK entity to the overseas parent company.

The Home Office uses these documents to assess whether your business and the roles you're offering meet the specific rules for the visa route. Consult with an experienced business immigration solicitor to make sure you're submitting everything required for your chosen category.

When and How to Submit Your Sponsor Licence Documents

After you complete your online Sponsor Licence application, you'll receive a submission sheet. This includes:

  • A checklist of the required documents
  • The email address to send your documents to
  • File format and naming instructions

Your Authorising Officer must sign and date the submission sheet. Then, you must email it along with all supporting documents within 5 working days of submitting your application.

Important: Do not send physical documents by post unless the Home Office specifically asks you to. Sending everything correctly and on time helps avoid delays or rejections.

What Happens If You Don't Submit the Right Documents?

If you don't provide the required mandatory documents, your sponsor licence application will be automatically rejected, no exceptions.

Here's what could happen:

  • Application rejected: If mandatory documents aren't submitted within 5 working days, the Home Office will reject your application without reviewing it.
  • Delay or refusal: Missing or incorrect documents can lead to delays or a full refusal, especially if additional information isn't provided when requested.
  • 6-month cooling-off period: If refused, you might not be able to reapply for a Sponsor Licence for at least 6 months.
  • No refund: If your application is refused, the Home Office won't refund your application fee.

Don't Risk Your Application Being Refused

Submitting the correct supporting documents is one of the most important steps in your sponsor licence application. Even if your business meets all the requirements, your application can still be refused if you fail to send the right paperwork.

If you're unsure which documents apply to your business or visa route, it's worth getting professional help from an immigration solicitor to avoid unnecessary delays or rejections.
