In this blog, you’ll get a clear idea of what this certificate is, why it matters, and how Visa Simple can support you throughout the process.

What is a Certificate of Sponsorship?

A certificate of sponsorship (CoS) is not a physical document but an electronic record issued by a licensed UK employer. Only employers with a valid sponsor licence can assign a CoS, and each certificate includes a unique reference number. Applicants must use that number when submitting their visa application.

The CoS also includes job details such as job title, salary, occupation code, and start date. It must be used within its validity period, which ensures the information stays accurate and relevant.

Why Certificate of Sponsorship Matters

  • Mandatory for visa applications: Most work-related UK visas require a valid certificate of sponsorship. Without it, the application cannot proceed.
  • Authenticates your job offer: A CoS ensures that a licensed UK employer has offered you a genuine role that meets immigration requirements.
  • Keeps your process organised: The certificate's unique number and validity window provide structure, helping applicants stay on track during their visa submission timeline.

Types of Certificate of Sponsorship

Two main types of CoS are commonly used:

  • Defined CoS: Assigned to applicants applying from outside the UK.
  • Undefined CoS: Assigned to individuals already inside the UK and switching to a qualifying visa category.

Employers must request or allocate the correct type based on their hiring needs.
