The United Kingdom remains a popular destination for international professionals seeking employment, career development, and better opportunities. Many British employers recruit qualified workers from outside the UK and support eligible applicants through the Skilled Worker visa route.
One important requirement for many foreign workers is a Certificate of Sponsorship (CoS). This is an electronic record issued by an approved UK employer that allows an eligible worker to apply for a work visa.
If you are searching for UK companies offering Certificate of Sponsorship jobs, this guide explains how the system works, which industries to explore, and how to find legitimate employers.
What Is a Certificate of Sponsorship?
A Certificate of Sponsorship is a unique electronic reference number assigned to a foreign worker by an employer licensed to sponsor workers in the UK.
It contains information about the job, salary, employer, and proposed employment.
A CoS is not a physical certificate or a visa. It is one of the requirements used when applying for an eligible work visa.
For the Skilled Worker route, the employer must generally:
- Hold a valid sponsor licence.
- Offer an eligible job.
- Pay the required salary.
- Assign a valid Certificate of Sponsorship.
- Comply with UK sponsorship regulations.
The worker must also meet the relevant visa requirements.

The UK government publishes a register of licensed sponsors.
You can use it to identify employers authorised to sponsor eligible foreign workers.

Being listed does not mean every vacancy is eligible for sponsorship.

Requirements for Getting a Certificate of Sponsorship
Applicants generally need:
- A genuine job offer from an approved sponsor.
- A job that meets the Skilled Worker eligibility rules.
- A salary that meets the applicable threshold.
- The required English-language ability.
- A valid passport.
- Supporting educational and professional documents.
The salary threshold and occupation requirements can change, so applicants should check the current government guidance before accepting an offer.
How Much Does a Certificate of Sponsorship Cost?
Employers pay the relevant fee to assign a Certificate of Sponsorship.
Workers should be cautious of anyone asking them to purchase a CoS or promising to sell sponsorship.
Certain sponsorship-related expenses are the employer’s responsibility and cannot lawfully be passed to the worker. Applicants should check the official rules before paying any recruitment or immigration-related charge.
How to Avoid UK Sponsorship Scams
Foreign applicants should be careful when dealing with unverified recruitment agencies.
Watch out for:
- Guaranteed visa approval.
- Fake job offers.
- Requests for payment to obtain a CoS.
- Employers with no verifiable business information.
- Recruitment agents using unofficial email addresses.
Always verify the sponsor through the official UK government register and communicate through genuine company channels.
