Common Sponsor Licence Mistakes (and How to Avoid Them)

Most sponsor licence problems are not deliberate fraud. They are routine, recurring administrative slips that compound until a Home Office trigger event surfaces them. Here are the most common, in roughly the order they appear during compliance visits.

1. Missing the 10-working-day reporting window

Salary changes, role changes, hours, location, and extended absence all carry a hard 10-working-day deadline. The HR system knows about the change instantly — the SMS portal only knows when someone logs in and reports it. Bridge the gap with automated alerts on the data sources that change first (payroll, time-and-attendance).

2. Annual salary "averaging" instead of per-period checking

Since 8 April 2026, SW 14.3B requires the salary threshold to be met in each rolling 3-month window for monthly-paid workers, not just annualised. A bonus-heavy comp plan that clears the annual minimum can still fail per-period — and it's the period view UKVI uses.

3. SOC code drift

A worker hired as a Care Worker (6135) who has been functionally running a small team for six months may be doing Senior Care Worker (6136) work. The CoS still says 6135. That's a role change and a reportable event — and the SOC change triggers a different going rate.

4. Undeclared work locations

Sponsors with multiple sites must declare every site the worker operates from. New client sites, new project sites, and even hot-desking arrangements at a parent company's office count.

5. Stale right-to-work checks

Time-limited visas require follow-up right-to-work checks before expiry. A missed follow-up exposes the sponsor to civil penalties as well as licence consequences.

6. Letting CoS expire unused

Assigned CoS that aren't used to apply for a visa within 3 months expire. Bulk expiry of unused CoS is a pattern auditors flag — it suggests poor recruitment forecasting, which feeds wider compliance suspicion.

7. Authorising Officer turnover not reported

When the Authorising Officer or Key Contact leaves the business, the change must be reported promptly through SMS. Operating a licence with stale role-holders is itself a compliance breach.
