Fake UK Certificate of Sponsorship Scams 2026: How to Spot and Avoid Them

A Certificate of Sponsorship, known as a CoS, is a digital record that a licensed UK employer assigns to a named worker for a specific job. It is not a paper certificate, it cannot be bought on its own, and it only works as part of a genuine job offer from a licensed sponsor. Anyone asking you to pay for a CoS, especially thousands of pounds to an agent you have never met, is almost certainly running a scam.

The safest rule is simple: verify the employer on the official UK register of licensed sponsors, confirm the job is real through an interview with the employer, and never pay an agent for sponsorship itself. Genuine UK employers pay the sponsorship costs themselves, and the only large payments a worker makes are the visa fee and the Immigration Health Surcharge, both paid to the UK government.

The most common version starts on social media or a messaging app, where an agent advertises UK jobs with sponsorship, often in care work, hospitality or warehousing. The agent promises a fast visa, a high salary and no experience needed, then asks for an upfront payment for the CoS, a job offer letter or processing fees. The payment is usually requested by bank transfer, cryptocurrency or a money transfer service that is hard to trace.

In some cases the victim receives a fake CoS number or a forged offer letter and is told to apply for a visa, which is then refused. In other cases the victim is told the visa is approved, travels to the UK, and discovers there is no job, no employer and no accommodation. A related scam involves real licensed sponsors whose details are stolen and used without their knowledge, which is why checking the sponsor directly matters.

A newer variation targets care workers, where a small sponsor issues CoS numbers for jobs that do not exist and takes a cut of the fee. The UK government has revoked licences of sponsors found doing this, and workers caught in the middle can lose their visa status through no fault of their own. That is why the job itself, not just the licence, needs to be real.

The clearest red flag is any request to pay for a CoS, a job offer or sponsorship. Genuine employers do not sell jobs, and a recruiter who charges a worker for sponsorship is breaking the rules. Other warning signs include pressure to pay quickly, demands for payment by untraceable methods, and fees that keep growing with new charges for documents, training or insurance.

Watch for jobs that sound too good to be true: high salaries for unskilled work, no interview, no experience required and an immediate start. Real employers interview candidates and check qualifications. If the only contact is a messaging app, there is no company website or verifiable address, and the agent refuses a video call, walk away.

Poor documentation is another warning sign. Spelling mistakes, generic email addresses, no company registration number, or an offer letter that does not match the sponsor's registered name all suggest fraud. A genuine offer letter names the employer, the job title, the salary, the working hours and the CoS reference, and it can be checked against the sponsor register.

Start with the official register of licensed sponsors on GOV.UK and search for the employer's exact name. The register shows whether the sponsor is licensed, what type of workers it can sponsor and its rating. If the employer is not listed, it cannot sponsor you, whatever the agent claims.

Next, contact the employer directly through the contact details on its own website, not through the agent's phone number. Ask to speak to the hiring manager, confirm the job exists, and ask for the CoS reference number and the details of the role. A genuine employer will expect these questions and will answer them.

You can also check the company on Companies House, look for genuine reviews and a real online presence, and confirm that the salary meets the minimum for the Skilled Worker route. The minimum salary threshold and the going rate for the occupation both apply, and an offer far below either is a sign the job is not genuine or not eligible for sponsorship.

If you have been contacted by a suspected scammer, do not pay anything and do not share your passport, bank details or other personal documents. Save screenshots of every message, advert and payment request, and keep a record of phone numbers, account details and any documents you received.

Report the scam to Action Fraud, the UK's national fraud reporting service, and to the police in your own country. If an agent in your country is involved, report them to the relevant licensing or labour authority there. Reporting rarely recovers money, but it creates a record and can help authorities shut the operation down.

If you have already paid or submitted a visa application using a suspicious CoS, seek advice from a regulated immigration adviser before taking further steps. Do not travel on a visa linked to a fake CoS, and do not use forged documents, because that can lead to a refusal and a ban from future UK visas.

The safest route is to apply directly to licensed sponsors through their own careers pages, the NHS Jobs website for healthcare roles, or established recruitment platforms that list verified employers. SteadStaff lists vacancies from employers and connects candidates with real hiring organisations rather than selling sponsorship.

For care work, check that the employer is registered with the Care Quality Commission and has a genuine care business, not just a sponsor licence. For other sectors, look for employers with a track record of sponsoring workers, and be wary of very new sponsors offering many roles with no visible business behind them.

A regulated immigration adviser can check a sponsor and a CoS for you, and in the UK advisers must be regulated by the OISC or be qualified solicitors. Paying for regulated advice is very different from paying an agent for a CoS: one is a professional service, the other is a scam.
