Extending a Skilled Worker Visa With a Pre-April 2024 CoS — What Salary Rules Apply?
HR CHECKED Compliance Team·12 Apr 2026·12 min read
## Who this affects
This guide is for Skilled Worker sponsors and workers where the Certificate of Sponsorship (CoS) was assigned before 4 April 2024. It matters most at extension time, when payroll and SMS data must match the rules that actually apply to that worker.
## Old vs new salary thresholds
For planning discussions, sponsors often contrast:
- Before 4 April 2024: a commonly cited general minimum was £26,200 per year or the SOC going rate, whichever was higher.
- After 4 April 2024: a higher general minimum of £38,700 in many cases, alongside updated going rate tests.
These numbers are not interchangeable. Which floor matters depends on whether transitional rules apply to that extension.
## When transitional rules may apply
Transitional protection can matter when all of the following align:
- The worker's CoS was assigned before 4 April 2024
- They are extending, not switching employer
- They remain with the same employer in the same role and SOC code
- Their leave has not expired in a way that forces them onto wholly new rules
When this protection applies, the £38,700 headline minimum may not be the correct comparator for that extension.
## When new rules apply instead
Employers should assume new-rule salary expectations are in play if:
- The worker changes employer
- The worker changes job role or SOC code
- Leave expires before extension
- A new CoS is assigned after 4 April 2024
- A salary change triggers a new CoS
## HC 1691 still applies to everyone
HC 1691 per-period salary compliance is a separate layer. Even where transitional logic applies to an extension, each payslip must still satisfy HC 1691 against the SOC going rate. Do not treat a lower general minimum as permission to underpay in individual pay periods.
## Action steps for employers
1. Identify workers whose CoS was assigned before 4 April 2024 who are approaching extension.
2. Reconcile contract, payroll, and SMS so the correct threshold story is reflected in evidence packs.
3. Run HC 1691 checks per period — HR CHECKED surfaces payslip-level risk early.
4. Link audits to GOV.UK transitional guidance rather than informal summaries.
## Action steps for workers
1. Confirm your CoS assignment date and extension route with your employer or adviser.
2. Do not assume £38,700 is your personal minimum until transitional rules have been checked.
3. Keep payslip evidence consistent with HC 1691 — that obligation is not waived by transitional salary treatment.
