What is a work permit?
A work permit gives a foreign national the legal permission to work in a country. In the UK, the term is still widely used, but most overseas workers now need a work visa, often supported by employer sponsorship. Without the correct employment authorisation, someone cannot legally take up a job in the UK.
Why are work permits important?
Work permits help governments manage legal employment, protect workers' rights, and maintain a fair labour market. They also give employers confidence that overseas hires have the correct permission to work. This reduces the risk of illegal employment and costly penalties.
They're important because they:
- Help prevent illegal working and immigration fraud.
- Protect wages and working conditions by ensuring employers follow employment laws.
- Hold employers accountable through sponsorship and compliance rules.
The UK has stepped up immigration enforcement in recent years. During 2025, the Home Office issued 2,438 civil penalties to employers for illegal working, with fines totalling more than £130 million, highlighting why checking employment authorisation is essential before hiring.
Who needs a work permit?
Anyone who does not automatically have the right to work in the UK will usually need permission before starting a job. While many people still search for "work permit UK", this permission is now generally granted through a work visa, such as the Skilled Worker visa.
People who typically need a work permit or work visa include:
- Foreign nationals coming to the UK for employment.
- People offered a job by a UK employer with a Home Office sponsor licence, where sponsorship is required.
- Workers applying under routes such as the Skilled Worker, Health and Care Worker, Seasonal Worker, or other eligible work visas.
People who generally do not need a work permit include:
- British and Irish citizens.
- Eligible people with settled or pre-settled status under the EU Settlement Scheme.
Before anyone starts work, UK employers must carry out a right to work check. Failing to do so can lead to significant fines and other enforcement action.
How does a work permit application usually work?
In the UK, what many people call a work permit application is usually an application for a work visa. In most cases, the employer starts the process by sponsoring the worker before the individual submits their visa application.
Here's how it typically works:
- Receive a job offer from a UK employer authorised to sponsor overseas workers.
- The employer assigns a Certificate of Sponsorship (CoS), which contains details of the role and a unique reference number.
- The worker submits an online visa application and provides the required documents, such as their passport, CoS reference, and any supporting evidence requested.
- The Home Office assesses whether the applicant meets the relevant eligibility requirements, including the job, salary, and immigration rules.
- Once approved, the worker can travel to the UK or begin work if they're already eligible to do so under their visa conditions.
Work permit vs work visa
In the UK, "work permit" is an older term. Today, most overseas employees apply for a work visa under the UK's points-based immigration system, often with employer sponsorship.

What happens if someone works without a valid work permit?
If a worker does not have valid employment authorisation, they could face:
- Refusal or cancellation of their visa.
- Removal from the UK, depending on their immigration status.
- Difficulty obtaining UK visas in the future due to previous immigration breaches.
For employers, the risks can be even greater:
- Civil penalties of up to £45,000 per illegal worker for a first breach, rising to £60,000 per worker for repeat breaches.
- Suspension or revocation of their sponsor licence, preventing them from sponsoring overseas workers in the future.
