Comprehensive guide to work visa restrictions on employment changes in the UK. Explains when visa updates or new applications are required for job changes, employer switching, occupation code changes, eligibility criteria, application timing, compliance obligations and practical steps for workers and employers.
Work visas in the United Kingdom, such as the Skilled Worker visa and other sponsored routes, permit overseas nationals to live and work in the UK under specific conditions set by UK Visas and Immigration (UKVI). One area of immigration law that often causes confusion is restrictions on employment changes, including switching employers, changing roles, or taking additional employment. These restrictions are central to maintaining lawful immigration status and avoiding breaches of visa conditions. This guide explains the legal framework, when changes require a new application, time limits, consequences for non‑compliance, and practical steps both employees and employers should understand. It is intended to be accessible to members of the public, students, and solicitors alike.
Legal Framework for Employment Changes
Most work visas operate under the Immigration Rules and related Home Office guidance. For sponsored routes, such as the Skilled Worker visa and its successors, the key restriction is that the visa is tied to the role and employer specified in the Certificate of Sponsorship (CoS). A change in employer or a materially different role usually means that the existing visa no longer correctly reflects the conditions under which the applicant was granted permission to stay and work.
Under UKVI rules, a visa holder must apply to update their visa if their circumstances change in specific ways that affect their eligibility. Unless permitted by transitional provisions or specific exemptions, failure to secure updated permission can result in unlawful working and future immigration difficulties.
When a Change Requires a New Visa or Update Application
Switching Employer
A fundamental restriction for sponsored workers is that changing employers always requires a new visa application. This is because a new sponsor must assign a CoS for the new employment and the applicant must apply for updated permission before starting work. You cannot begin the new role until UKVI has approved the updated visa.
Changing Job Role with the Same Employer
Even if you remain with the same employer, you may need to apply to update your visa if your core duties change significantly. UKVI treats this as a change of employment if the new role falls into a different occupation code from the one specified on your original CoS. A fresh CoS and visa application are generally required in these circumstances.
Changes to Occupation Code
If your job moves into a different Standard Occupational Classification (SOC) code, a new visa application is typically required. This reflects that UKVI assesses eligibility on the basis of specific roles and their corresponding codes at the time permission is granted.
Supplementary and Second Jobs
You may be permitted supplementary employment under certain conditions, such as limited hours or qualified occupation codes, without applying for a new visa. For example, UKVI guidance allows additional work of up to 20 paid hours per week in a role that meets eligibility criteria. However, full‑time second employment often requires updated permission.
Eligibility Criteria and Role Requirements
When applying to update a visa after a change of employment, the new role must meet the eligibility requirements of the visa category:
- Skill level: Under the updated rules introduced in 2025, jobs generally must be at Regulated Qualifications Framework (RQF) Level 6 or above to qualify for the Skilled Worker and equivalent routes, with transitional exceptions for existing visa holders in certain roles.
- Salary threshold: The job must meet the required minimum salary as set in the Immigration Rules at the time of application.
- Certificate of Sponsorship: A new CoS must be issued by the sponsor to support the updated application; this confirms UKVI that the job offer and employer meet requirements.
If the new job does not meet these criteria, the visa application will be refused. In such cases, the applicant may need to reconsider the job offer or explore eligibility under a different visa category.
Timing and Application Process
When to Apply
Applicants can submit an application to update their visa up to three months before the start date of the new job or role. You must apply before starting the new job unless UKVI guidance explicitly permits a transitional period within your current visa conditions.
Continuity of Right to Work
If you apply to update your visa in good time - before your current permission expires and before starting the new job - you may continue working in your current role while the application is being processed, including serving notice periods. However, you must not commence work in the new role until UKVI has granted updated permission.
Application Outcomes
A successful visa update results in a new visa grant reflecting your new employer and/or role. This permit governs your ongoing right to work in the UK. An unsuccessful application can lead to loss of lawful status and potential enforcement action.
Consequences of Non‑Compliance
Failing to apply for visa updates when required can have serious consequences:
- Breach of visa conditions: Working in a different job without updated permission is a breach of immigration law and may lead to visa curtailment or refusal of future applications.
- Right to work issues: Employers who allow visa holders to start a new job without approval risk unlawful working liabilities and sanctions against their sponsor licence.
- Impact on settlement: Repeated breaches or unlawful working can affect eligibility for Indefinite Leave to Remain or other permanent status applications, as continuous lawful residence is a key requirement.
Practical Considerations for Employers and Workers
Employer Obligations
Employers must assign a new CoS for any change requiring updated permission and ensure that the job meets immigration eligibility criteria. They must also conduct right to work checks before the employee starts the new role and refrain from allowing work in an unapproved position.
Worker Checklist
Work visa holders considering an employment change should:
- Confirm whether the change triggers a requirement to update their visa;
- Check that the new job meets skill level and salary thresholds;
- Apply for updated permission before starting the new role;
- Maintain communication with both current and prospective employers regarding timing and compliance.
Failing to plan can leave individuals without authorised work rights or facing enforcement action.
Common Questions
Do I need a new visa if I change roles within the same organisation?
Yes - if your new job has different duties or a different occupation code, you will generally need to apply to update your visa and secure a new CoS before commencing the role.
Can I start the new job before the updated visa is granted?
No. You must wait for UKVI to approve your updated visa before starting the new job, unless specific guidance allows interim work under your existing terms.
What if my visa is due to expire soon?
Submit your visa update application well before the current visa expires. You can continue working in your existing job while the update is being processed, provided you applied in time.
Key Takeaways
UK work visas impose specific restrictions on employment changes to ensure that visa conditions reflect current job roles and responsibilities. Changing employers or materially different roles normally requires a new visa application supported by a fresh Certificate of Sponsorship. Workers must apply for updated permission before starting the new job, meet eligibility criteria including skill level and salary thresholds, and comply with timing requirements. Employers must assign appropriate CoS and ensure right to work compliance. Understanding these restrictions and planning ahead reduces the risk of unlawful work, visa refusal, or adverse impacts on future immigration status.
