The Home Office’s latest updates to sponsor guidance in March 2026, alongside broader immigration rule changes introduced this year, signal a decisive shift in the UK’s sponsorship regime. The direction of travel is clear: compliance expectations are rising, scrutiny is intensifying, and enforcement action is increasing.
For sponsor licence holders, the message is straightforward compliance will be tested. The question is no longer if, but when.
A clear trend: rising revocations
The Home Office has already signalled its approach. In September 2025 alone, 1,948 sponsor licences were revoked. This figure is not incidental; it reflects a deliberate enforcement strategy. The updated guidance reinforces this trajectory, with stronger wording, broader duties, and lower thresholds for intervention.
Sponsors should proceed on the basis that compliance breaches particularly systemic or historical ones, are increasingly likely to result in suspension or revocation.
New and expanded compliance duties
The March 2026 updates introduce several important obligations that require immediate attention:
- Evidence of worker rights and welfare information
Sponsors must now retain evidence that all sponsored workers, not just new hires have been informed of their employment rights in the UK.
Appendix D has been updated to require sponsors to retain evidence that they have told their sponsored employees or workers about their employment rights in the UK. Paragraph L2.7 of part one puts it plainly:
You must have human resources systems or processes in place which demonstrate that you provide this information to any employees or workers you sponsor. You must retain this evidence for any workers you sponsor, in accordance with Appendix D to this guidance.
Employers should retain the following :
- Contracts of employment
- Written guidance provided to workers
- Training or onboarding materials
This is not a prospective obligation. If this evidence does not exist for current sponsored workers, the organisation is already in breach. Retrospective remediation is essential.
- The “eligible role” test
A newly defined concept of an “eligible role” introduces a stricter framework for assessing whether a role genuinely qualifies for sponsorship. The Home Office must be satisfied that:
- The role genuinely exists at the point of assigning the Certificate of Sponsorship
- The duties, skill level and salary meet route requirements
- The role aligns with the organisation’s business model and scale
- These conditions will continue throughout the sponsorship period
This creates a clear basis for the Home Office to challenge roles that appear artificial, inflated, or disconnected from genuine business need particularly in self-sponsorship or newly created roles.
- Accuracy of occupation codes and job descriptions
The guidance now explicitly states that if a worker’s actual role does not match the occupation code or job description on their Certificate of Sponsorship, this is a mandatory ground for revocation.
This significantly raises the stakes for:
- -Promotions
- Role changes
- Internal restructures
Sponsors must ensure that any changes are either reported within the required timeframe or, where necessary, a new Certificate of Sponsorship is assigned.
- Expanded right to work obligations
Sponsors are now under a positive duty to verify the right to work status of individuals who are not their direct employees but are working within their sponsored structure.
Where workers are employed by a related entity, sponsors must:
Obtain and retain evidence of right to work checks conducted; or
Conduct their own checks
This extends compliance risk beyond direct employees and requires stronger coordination across group structures.
A stricter legal and operational framework
The updated guidance also reframes the relationship between sponsors and the Home Office. The introduction of language such as “reasonable concern” and “reasonable suspicion” lowers the threshold for refusal, suspension, and revocation decisions.
Crucially, the guidance reiterates that a sponsor licence:
- Is discretionary
- Confers no enforceable right
- Can be revoked where suitability is in doubt
This signals a move away from the “trusted partner” model towards a more enforcement-led regime.
Additional 2026 changes increasing risk exposure Recent rule changes further heighten compliance risk:
Salary compliance: From April 2026, salary thresholds must be met in each pay period. Errors in a single payroll cycle may now constitute non-compliance.
Recruitment restrictions: Changes affecting asylum seekers introduce stricter eligibility criteria for new hires, requiring careful pre-employment assessment.
These changes increase the likelihood that routine operational issues such as payroll discrepancies or recruitment processes can escalate into sponsor licence risks.
Why an audit is now essential
Given the cumulative effect of these changes, sponsors should not rely on existing systems or historic compliance assumptions. Many breaches arise not from deliberate misconduct, but from:
- Legacy practices no longer aligned with updated guidance
- Incomplete record-keeping
- Unreported role changes
- Misalignment between HR, payroll, and immigration functions
A structured compliance audit allows organisations to Identify gaps across their sponsored workforce, rectify issues before Home Office intervention, strengthen internal systems and reporting lines, mitigate the risk of suspension or revocation.
April 2026 Immigration Rule Updates: Key Changes Impacting Sponsors
Alongside the compliance-focused guidance updates, a series of immigration rule changes introduced in early 2026 that further increase sponsor risk exposure and operational complexity.
Skilled Worker salary compliance: the “pay period” rule
From 8 April 2026, skilled worker salary compliance moves away from a purely annual assessment to a pay-period-based system.
Key requirements:
- Salary must meet or exceed the required level in each pay period
- Workers must be paid at least monthly (unless contractually specified otherwise)
- Additional thresholds apply depending on pay frequency
- Special rules apply for irregular working patterns
This change allows the Home Office to identify underpayment in real time, supported by payroll data shared by HMRC.
Compliance impact:
- Even a single payroll error may trigger scrutiny
- Sponsors must closely monitor deductions, variable pay, and salary fluctuations
- All salary changes must be reported within 10 working days
For sponsor licence holders, the message is straightforward compliance will be tested. The question is no longer if, but when.
Increased payroll scrutiny and enforcement risk
With HMRC data-sharing in place, discrepancies between reported and actual pay are more likely to result in:
- Information requests
- Compliance visits
- Licence suspension or revocation
Sponsors should prioritise alignment between payroll and sponsorship reporting systems.
Recruitment restrictions: Afghan “visa brake”
From 26 March 2026, applications for Skilled Worker visas from Afghan nationals applying from outside the UK are being refused, regardless of when the Certificate of Sponsorship was issued.
This measure is described as temporary and remains under review.
Compliance impact:
- Sponsors must apply stricter eligibility checks at the recruitment stage
- Incorrect hiring decisions could result in compliance breaches
Changes to Global Business Mobility routes
Secondment Worker route
From 8 April 2026, the overseas employment requirement is reduced from 12 months to 6 months, increasing flexibility for high-value projects.
Service Supplier route (UK–India agreement)
New provisions allow certain Indian service suppliers to work in the UK for up to 12 months, reflecting trade commitments.
Compliance impact:
- Sponsors using these routes must ensure correct eligibility assessments and documentation
English language requirements for settlement
The English language requirement for settlement (ILR) across several visa routes will increase from B1 to B2, with implementation scheduled for 26 March 2027.
Compliance impact:
- Sponsors should factor this into long-term workforce planning and employee support
Conclusion
Taken together, the 2026 guidance updates and rule changes represent a fundamental tightening of the UK sponsorship system.
The combined effect is:
- Greater scrutiny of sponsor activity
- Real-time monitoring of compliance (especially payroll)
- Broader and more complex sponsor duties
- Faster and more frequent enforcement action
For sponsor licence holders, the risk landscape has materially changed. Organisations should act now to review and strengthen their compliance frameworks to ensure they are prepared for increased Home Office scrutiny.
