What Are COS Jobs in the UK?
COS stands for Certificate of Sponsorship. It’s an electronic document assigned by a UK-based, Home Office-approved employer to a foreign national they wish to hire. The COS enables the individual to apply for a Skilled Worker visa (or Health and Care Worker visa, depending on the job).
There are two types of Certificates of Sponsorship:
- Defined COS: For applicants applying from outside the UK.
- Undefined COS: For people already inside the UK switching to or extending a visa.
In both cases, a valid COS is required to lodge a successful visa application under the points-based immigration system.
Why COS Jobs Matter in 2025
The UK is facing labour shortages in key sectors such as healthcare, tech, education, and hospitality. This has led to an increase in UK employers seeking overseas talent and becoming sponsorship licence holders.
With Brexit restricting EU migration and a growing need for skilled workers, COS jobs have opened up tremendous opportunities for international professionals to enter the UK legally.
