Executive Summary
- The Home Office introduced significant changes to sponsor guidance in March 2026, with further amendments to the Immigration Rules taking effect on 8 April 2026.
- Unintentional compliance breaches now carry a real risk of mandatory licence revocation, not just a warning or suspension.
- New salary rules require compliance to be assessed each pay period, not just on an annual average basis.
- Right to work checks have been extended beyond direct employees to include contractors, secondees, and other non-employed personnel.
- UKVI enforcement has intensified significantly. Over 3,000 licences were revoked in 2025, with revocations tripling in the final quarter.
What changed and why it matters
Since March 2026, the Home Office has been moving sponsor licence compliance into a stricter framework. The changes that took effect on 8 April 2026 continue that shift.
The most significant change is not any single rule. It is the overall direction of travel. Compliance breaches that were previously handled with a warning or a suspension are now more likely to result in mandatory revocation. This applies even where the breach was unintentional.
For HR teams managing sponsored workers in the UK, that changes the risk calculation considerably.
The new mandatory revocation triggers
Under the updated rules, certain situations now carry mandatory revocation risk rather than discretionary action. These include:
- Role or salary discrepancies. If a sponsored worker's actual role or salary does not match what was listed on their Certificate of Sponsorship (CoS), that is now a revocation risk. This is not a technicality. It means any undocumented role changes, title changes, or salary adjustments need to be reviewed against the CoS immediately.
- Recovering Immigration Skills Charge or CoS fees from workers. Seeking to recoup these costs from employees is prohibited. If this practice exists anywhere in your business, it needs to stop.
- Regulatory failures. Sponsors who are required to maintain regulatory registration (such as CQC registration in healthcare) must keep that registration current. Letting it lapse is now grounds for mandatory revocation.
- Right to work failures. Failing to conduct compliant right-to-work checks now carries significantly greater sponsor licence risk. See the section below on expanded right-to-work duties.
New salary compliance rules (effective 8 April 2026)
This is one of the most operationally impactful changes. Previously, salary compliance was assessed on an annual basis. Now, it must be assessed during each relevant pay period.
What this means in practice:
- Monthly or less frequent payroll: Salary over any three-month period must meet at least one quarter of the annual minimum salary threshold.
- More frequent pay cycles: Salary over any 12-week period must meet 12/52 of the annual minimum salary threshold.
- Variable-hours workers: A 17-week assessment period may apply.
This matters most where pay fluctuates due to shift patterns, where salary is weighted unevenly across the year, where deductions affect the gross calculation, or where workers are paid on non-standard cycles.
HR and payroll teams need to work together on this. Running payroll correctly on an annual average basis is no longer sufficient. Review your payroll processes against these new thresholds now, before a UKVI inspection makes that review happen for you.
Expanded right to work checks
The updated sponsor guidance extends right-to-work check obligations beyond your direct employees. Sponsors may now be required to conduct checks on anyone "directly engaged" by the business, which can include:
- Self-employed contractors
- Secondees
- Other non-employed personnel working within the business
This is a meaningful change. Many companies have onboarding processes that only capture direct hires. If your business regularly engages contractors or secondees, your current right-to-work procedures may not be sufficient under the new guidance.
Review your onboarding and contractor engagement processes against the updated guidance. If you are unsure whether specific categories of workers are covered, consult a UK immigration advisor before your next engagement cycle.
A new duty to monitor sponsor guidance
Sponsors are now expressly required to read all relevant sponsor guidance in full and stay aware of updates published by UKVI. The Home Office has also made clear that sponsors must monitor the Sponsor Management System (SMS) message board regularly.
This is not a soft expectation. It is a formal compliance obligation. The practical recommendation from immigration advisors is that Level 1 Users should log into SMS at least once per month and treat it as a recurring calendar task.
UKVI enforcement is increasing
The compliance changes are happening alongside a significant increase in enforcement activity. The numbers from 2025 are a clear signal of where this is heading:
- Over 3,000 sponsor licences were revoked in 2025.
- Revocations tripled in the final quarter of 2025.
- Enforcement has continued into 2026.
UKVI is also issuing Further Information Requests (FIRs) at short notice, requiring sponsors to provide documents including employment contracts, bank statements, payslips, RTI and payroll reports, P60s, and evidence of salary payments. Failure to respond adequately within the deadline can result in revocation.
The Home Office is increasingly using AI-driven analysis and real-time data sharing with HMRC, PAYE, and Companies House. This means compliance issues can be identified without a site visit. Assuming that no news from UKVI means everything is fine is no longer a safe assumption.
What happens if a licence is revoked
The consequences of revocation are serious and affect both the company and the workers it sponsors:
- Sponsored workers typically have their visas curtailed to 60 days.
- The company loses the ability to sponsor migrant workers immediately.
- There is currently a 12-month bar on reapplying for a sponsor licence, with proposals to extend this to 24 months.
For a company that relies on international talent, losing the sponsor licence is an operational crisis, not just a compliance setback.
The immediate actions HR should take
Based on the April 2026 changes, sponsor licence holders should:
- Conduct an internal sponsor compliance audit against the updated guidance.
- Review all active CoS assignments to confirm they match current roles and salaries.
- Audit payroll processes against the new per-pay-period salary compliance rules.
- Expand right to work check procedures to cover contractors, secondees, and other directly engaged workers.
- Ensure HR and employment contract records are fully up to date.
- Set up a monthly SMS monitoring task for Level 1 Users.
- Prepare a response protocol for UKVI Further Information Requests, including knowing where your payroll records and contracts are and who is responsible for responding.
