Certificates of Sponsorship & Sponsored Workers
Changes to a Sponsored Worker's Role, Salary or Location
Some changes need reporting; others may need a new application. Check before you make them.
Book a compliance consultation
What the issue is
Promotions, pay changes, reduced hours, new sites or remote working can affect a sponsored worker's permission and the sponsor's reporting obligations.
Why it matters
Some changes require only a report; others may require the worker to make a new application. Making the change first can create a breach.
When advice may be appropriate
Before any change to occupation code, salary reductions or significant changes in working arrangements.
Common failures
- Reducing pay below the level on the CoS.
- Moving a worker to a new site without considering reporting.
Evidence to keep
Examples to consider where relevant — not a complete or mandatory list.
- Change approvals and dates.
- Reports made or advice obtained.
Practical preventative steps
- Add an immigration check to change approvals.
