Skilled Worker Visa: How To Switch Employer Legally

Changing Employer on a Skilled Worker Visa

A Skilled Worker visa is tied directly to a specific sponsoring employer and an approved job role. This means a visa holder cannot freely change jobs in the UK without following formal immigration procedures. Switching employer requires a new Certificate of Sponsorship (CoS) and a new application to update permission to stay under the Skilled Worker route.

UK immigration rules require that any material change in employment-particularly a change of employer or occupation code-must be approved by UK Visas and Immigration (UKVI (UK Visas and Immigration)).

This guide explains the legal process for switching employers, including eligibility, documentation, timing, risks, and compliance requirements.

Step 1: Understand When You Must Apply to Switch Employer

A new Skilled Worker visa application is required when:

• Changing employer (even within the same industry)
• Moving to a different occupation code
• Leaving a sponsored role and joining a new sponsor
• Taking a job that materially differs from the original sponsored role

In most cases, switching employer is treated as a new immigration application rather than a simple update to existing permission.

A visa holder must not begin working for the new employer until permission has been granted.

Step 2: Secure a Job Offer from a Licensed Sponsor

Before any immigration application can begin, the individual must obtain:

• A confirmed job offer
• An employer holding a valid Home Office sponsor licence
• A role that meets Skilled Worker eligibility requirements

If the employer is not licensed, they must apply for and obtain a sponsor licence before issuing sponsorship.

The role must also meet:

• Eligible occupation code (SOC code)
• Minimum skill level requirement
• Salary threshold (general rule: at least £41,700 or the going rate, subject to exceptions and transitional arrangements)

Step 3: Obtain a New Certificate of Sponsorship (CoS)

The Certificate of Sponsorship is a mandatory requirement for switching employer.

It is an electronic record issued by the new employer confirming:

• Job title and duties
• Occupation code
• Salary and working hours
• Start date
• Sponsor details

The CoS must be assigned before the visa application is submitted, and the application must generally be made within three months of CoS issuance.

Errors in the CoS (such as incorrect occupation coding or salary mismatch) are a common cause of refusal.

Step 4: Check Whether You Can Apply From Inside the UK

Most Skilled Worker visa holders can apply to switch employer from within the UK, provided they hold valid immigration status.

However, individuals in certain immigration categories cannot switch from inside the UK (for example, visitors or some short-term visa holders). In those cases, they must leave the UK and apply from abroad.

Applicants must not travel outside the UK, Ireland, Channel Islands, or Isle of Man while the application is pending, as this will normally withdraw the application.

Step 5: Confirm Salary and Occupation Code Compliance

The new job must meet salary and occupation requirements. Key legal considerations include:

• Salary must meet the higher of the general threshold or occupation-specific “going rate”
• Some transitional applicants may qualify under lower thresholds depending on when their original CoS was issued
• The occupation code must accurately reflect job duties (not job title alone)
• The Home Office will assess whether the role is genuine and properly classified

Incorrect classification can result in refusal or future compliance issues for both employer and employee.

Step 6: Submit the Skilled Worker Visa Application

The application is completed online through the UKVI system.

It requires:

• Personal details and passport information
• CoS reference number
• Employment and salary details
• Supporting documents

Applicants must also pay:

• Visa application fee
• Immigration Health Surcharge (IHS)

Once submitted, the application is considered an in-country immigration request to vary existing permission.

Step 7: Prove Identity and Provide Biometrics

Applicants must verify identity using one of the following:

• UK Immigration: ID Check app (digital identity verification), or
• Appointment at a UK Visa and Citizenship Application Services (UKVCAS) centre

This includes:

• Fingerprints
• Photograph
• Document verification (where required)

Step 8: Work Conditions While the Application Is Pending

Once a valid application has been submitted:

• The applicant can usually continue working for their current employer
• They must not start work for the new employer until approval is granted
• Changing employers before approval can constitute unlawful employment

A key legal risk in this stage is premature job commencement, which may lead to visa cancellation or future immigration refusal.

Step 9: Home Office Decision and Outcome

UKVI will assess:

• Validity of sponsorship
• Salary compliance
• Occupation code accuracy
• Genuine vacancy requirement
• Immigration history

If approved:

• Permission is updated to reflect the new employer
• The individual can legally begin employment with the new sponsor
• Dependants may need separate updates depending on circumstances

If refused:

• Reasons will be provided in a refusal notice
• Options may include administrative review or a new application
• Continued employment rights may be affected depending on timing and status

Step 10: After Approval – Compliance Obligations

After switching employer, the visa holder must:

• Work only for the new sponsoring employer
• Remain in the approved occupation code and role
• Ensure salary continues to meet visa conditions
• Report material changes in employment circumstances where required

Failure to comply can lead to curtailment of leave and impact future settlement applications.

Common Legal Risks When Switching Employer

Frequent issues include:

• Starting new employment before visa approval
• Incorrect or inconsistent occupation coding
• Employer losing sponsor licence during application process
• Salary below required threshold
• Gaps between resignation and new sponsorship validity
• Applying too late, resulting in loss of lawful status

Immigration compliance failures may affect eligibility for Indefinite Leave to Remain (ILR), particularly where continuity of lawful residence is disrupted.

Practical Considerations for Employees

Although not legal requirements, several practical factors are commonly relevant:

• Timing resignation carefully to avoid employment gaps
• Coordinating start dates with CoS validity
• Ensuring notice periods align with visa approval timelines
• Reviewing long-term settlement eligibility after switching employers
• Confirming dependants' visa status after employer change

Final Thoughts

Switching employer on a Skilled Worker visa is a regulated immigration process requiring a new Certificate of Sponsorship and a formal application to update permission to stay. The key legal requirements are valid sponsorship, accurate job classification, salary compliance, and approval before starting new employment.

The most common risks arise from incorrect timing, occupation code errors, and premature job commencement. Proper sequencing of sponsorship, application submission, and employment transition is essential to maintain lawful status in the UK and preserve long-term immigration rights.
