Skilled Worker Visa Employer Switching Rules

The Skilled Worker visa is tied directly to a specific employer, job role, and Certificate of Sponsorship (CoS). Because of this structure, any change of employer is treated as a formal immigration event rather than a simple employment change. UK Visas and Immigration (UKVI) requires a new application whenever a worker moves to a different sponsoring organisation.

These rules are set out in the Immigration Rules (Appendix Skilled Worker) and supporting Home Office guidance on changes of employment. The system is designed to ensure that sponsored work remains genuine, appropriately paid, and carried out under licensed sponsorship control.

1. When a Skilled Worker Visa Requires Employer Switching

A Skilled Worker must apply for a new visa if they change employer. This is because the visa is not “portable” between sponsors.

A new application is required when:

• Moving to a different employer
• Changing to a new job that requires a different occupation code (SOC code)
• Moving into a role that materially changes the sponsored duties under the original CoS

UKVI treats these as “change of employment” situations, requiring a fresh application with a new CoS.

2. Legal Effect of Changing Employer

A Skilled Worker visa is legally linked to:

• The sponsoring employer
• The job description stated on the Certificate of Sponsorship
• The relevant occupation code
• The salary level agreed for that role

If any of these core elements change due to a new employer, the existing visa conditions no longer reflect the sponsored arrangement. This is why a new application must be submitted rather than a variation within the same visa.

Until the new visa is granted, the worker cannot begin employment with the new employer.

3. Requirement for a New Certificate of Sponsorship (CoS)

A new employer must issue a new Certificate of Sponsorship before an application can be made.

The CoS must:

• Confirm a genuine job vacancy
• Match an eligible occupation code under Skilled Worker rules
• Meet minimum salary thresholds for that occupation
• Be issued by a Home Office licensed sponsor

The CoS forms the legal basis of the new immigration application. Without it, a change of employer application cannot proceed.

4. Application Process When Switching Employers

The switching process generally follows these steps:

Step 1: Job offer from a licensed sponsor

The employer must hold a valid sponsor licence and be authorised to sponsor Skilled Workers.

Step 2: Issuance of a new CoS

The employer assigns a CoS for the new role through the Sponsorship Management System (SMS).

Step 3: Submission of a new Skilled Worker visa application

The worker applies to update or replace their permission under the Skilled Worker route.

Step 4: Identity verification and documents

Applicants may use the UK Immigration: ID Check app or attend a UKVCAS appointment.

Step 5: Await decision

Processing typically takes several weeks, unless priority services are used.

During processing, the applicant may continue working in their current role but must not start the new job until approval is granted.

5. Timing Rules and Restrictions

5.1 When to apply

An application can usually be submitted up to three months before the start date of the new job.

5.2 Travel restrictions

Leaving the UK, Ireland, Channel Islands, or Isle of Man while an application is pending may result in withdrawal of the application.

5.3 Starting the new job

Employment with the new sponsor cannot begin until UKVI grants permission.

6. Salary and Eligibility Requirements After Switching

When changing employer, the new role must meet all Skilled Worker requirements again:

• Minimum salary threshold (general or occupation-specific)
• Eligible occupation code
• Compliance with working time and employment law standards

Some applicants may qualify for transitional or “new entrant” salary rates depending on previous immigration status, but these depend on strict criteria and time limits set in Home Office guidance.

7. Impact on Immigration Status and Settlement

7.1 Continuous residence

A change of employer does not usually break continuity of residence for Indefinite Leave to Remain (ILR), provided lawful permission is maintained.

7.2 ILR qualifying period

Time already spent on Skilled Worker permission generally continues to count towards settlement.

7.3 Risk of gaps

Any period without valid permission or where the application is refused may interrupt ILR eligibility.

8. Common Employer Compliance Issues in Switching Cases

Employer-related errors frequently arise during switching applications:

Incorrect occupation coding

Misalignment between actual duties and SOC code can lead to refusal.

Salary mismatch

Failure to meet required salary thresholds is a common refusal ground.

Invalid sponsor licence

If the new employer's licence is suspended or revoked, the application cannot proceed.

CoS inaccuracies

Errors in job description or contract details may trigger UKVI scrutiny.

9. Employer Responsibilities During Switching

New sponsoring employers must:

• Hold and maintain a valid sponsor licence
• Assign accurate Certificates of Sponsorship
• Report relevant changes via SMS
• Ensure ongoing compliance with immigration and employment law
• Maintain records for potential Home Office audits

Failure to comply may result in licence downgrade, suspension, or revocation, affecting all sponsored employees.

10. Common Practical Scenarios

Scenario 1: Direct job change to new employer

A full new visa application is required before starting employment.

Scenario 2: Redundancy

Workers typically rely on their remaining leave to find a new sponsor and submit a fresh application.

Scenario 3: Internal transfer within company

A new application may be required if the occupation code changes, even if the employer remains the same.

11. Key Risks for Workers and Employers

• Starting new employment before approval (immigration breach)
• Incorrect CoS assignment leading to refusal
• Loss of lawful status if application is refused and no alternative leave exists
• Employer non-compliance leading to sponsor licence action

Final Thoughts

Switching employers on a Skilled Worker visa is not a simple employment change but a regulated immigration process requiring a new Certificate of Sponsorship and a full visa application. The system ensures that sponsorship remains tied to a licensed employer, an eligible role, and compliant salary levels.

Both employers and workers must follow strict procedural and timing rules to maintain lawful status and avoid immigration penalties. Careful compliance with Home Office requirements is essential throughout the transition.
