Sponsor licence revocation immediately ends a business’s authority to employ overseas workers, and the Home Office revoked over 3,100 licences in 2025 alone. Avoiding revocation requires more than good intentions: sponsors must understand the current grounds for revocation, keep pace with rule changes that came into force in March and April 2026, and run compliance systems capable of withstanding a Home Office visit without notice.

Summary
- The Home Office revoked 1,516 sponsor licences in Q4 2025 alone, reflecting a sustained enforcement drive that shows no sign of easing.
- From 8th April 2026, sponsored workers must be paid the required salary in each pay period, not just across an annual average; a single underpayment period is now a compliance failure.
- Working in a role that does not match the occupation code or job description on the Certificate of Sponsorship is, from March 2026, a mandatory ground for revocation.
- The Court of Appeal confirmed in Prestwick Care Ltd & Ors v Secretary of State for the Home Department [2025] EWCA Civ 184 that the Home Office has no duty to weigh the commercial impact of revocation where a mandatory breach is established.
- Revocation bars a sponsor from making a new application for 12 months; there is no right of appeal, and judicial review is the only available challenge route.
Between July 2024 and June 2025, the Home Office revoked 1,948 sponsor licences, more than double the 937 revoked in the preceding twelve months. Revocation removes a business’s authority to sponsor overseas workers under the Skilled Worker route immediately. Every sponsored worker’s visa becomes liable to curtailment, leaving those individuals 60 days to find a new sponsor or leave the UK. This forms part of our wider guide to the Skilled Worker Sponsor Licence and the compliance duties that attach to it.
The law governing sponsor licences in England and Wales is set out in the Immigration Act 1971 and the Immigration Rules made under it, read alongside the Home Office’s Workers and Temporary Workers sponsor guidance, which was updated in March and April 2026 and now carries considerably more compliance weight than its predecessors. Sponsors are required to read the guidance in full, including all three parts, the appendices, and the route-specific sections, and to remain aware of all subsequent updates. That obligation is now explicit, not implied.
What are the main grounds for sponsor licence revocation?
Revocation grounds fall into two categories: mandatory, where the Home Office has no discretion once a breach is established, and discretionary, where revocation is the likely but not inevitable outcome. Mandatory grounds include knowingly providing false information in the licence application, employing a worker whose role does not match the occupation code or job description on their Certificate of Sponsorship, and recovering the Immigration Skills Charge or sponsor licence fee from a sponsored worker. Discretionary grounds include failure to cooperate with a compliance visit and failure to pay the correct salary.
The March 2026 statement of changes to the Immigration Rules hardened the position on role accuracy. The Home Office replaced the term “genuine vacancy” with “eligible role” and made clear that a sponsored worker found to be carrying out duties that do not match those stated on their Certificate of Sponsorship (CoS) faces mandatory revocation proceedings against the sponsor, not a warning. Sponsors must notify the Home Office of any permitted role change within 10 working days using the Sponsorship Management System (SMS).
The April 2026 pay-period rule, now in SW 14.3B of the Immigration Rules, means that a sponsored worker’s pay must meet the required salary or going rate in every pay period, not averaged across the year. Any month in which pay falls below the threshold, whether through salary sacrifice, variable hours, or unpaid leave, creates a compliance failure that can support revocation. Payroll must be audited against the per-pay-period rule, not merely the annual contract salary.
The updated guidance also extended right to work check obligations. From March 2026, sponsors must carry out right to work checks on every worker they employ or directly engage, including self-employed workers, not just those they sponsor directly. Where a sponsor fails to carry out a check and an illegal worker is found, the Home Office will normally revoke the licence. The civil penalty under the Immigration, Asylum and Nationality Act 2006 can reach £60,000 per illegal worker, and revocation will typically follow.
What compliance systems reduce the risk of revocation?
The single most effective protection against revocation is a documented compliance system that sponsors can demonstrate to a Home Office inspector on arrival, without preparation time. Sponsors that cannot produce records of right to work checks, CoS audit trails, payroll reconciliations, and worker monitoring logs on request are at significant risk, regardless of whether the underlying employment was lawful. The Home Office’s compliance visit power allows unannounced attendance, and inspectors assess systems against current guidance, not the version in force when the licence was originally granted.
Six practical steps reduce revocation risk materially:
- Audit payroll in every pay period against the going rate for each sponsored worker’s SOC code. Flag salary sacrifice arrangements, variable-hours contracts, and any approved absence that could cause a pay-period shortfall.
- Review every CoS against the actual duties the worker is performing. Where duties have changed, assess whether the change is a permitted variation and report within 10 working days if required.
- Conduct right to work checks on all workers before engagement, not just sponsored visa holders. Retain the evidence in line with Appendix D of the sponsor guidance.
- Ensure the Level 1 User logs into the SMS at least once a month and reviews the message board for guidance updates. The March 2026 guidance change makes this a formal compliance duty.
- Provide sponsored workers with written information on their employment rights, including entitlement to the National Minimum Wage, Working Time Regulations compliance, and how to raise a grievance. Retain evidence of delivery.
- Never recover the Immigration Skills Charge, sponsor licence fee, or CoS fee from a sponsored worker. Recouping any of these costs, including through salary deductions, is a mandatory revocation ground for assignments made on or after 31st December 2024.
From 2026, the Home Office can also act on reasonable suspicion of a future breach, rather than only on a proven historical one. If a compliance officer has reasonable grounds to suspect that a sponsor is likely to breach its duties, that suspicion is now sufficient to trigger suspension pending investigation. A proactive internal audit, conducted by an immigration solicitor before any Home Office contact, is the most reliable way to identify and remedy weaknesses before they become enforcement matters.
What happens after revocation and can the decision be challenged?
Revocation takes effect immediately. All CoS assignments become invalid, all sponsored workers receive curtailment notices with 60 days to regularise their status, and the sponsor is barred from making a new application for 12 months. On any new application, the sponsor must address the reasons for the previous revocation and demonstrate that the breaches have been remedied. There is no statutory right of appeal against revocation.
The Court of Appeal confirmed in Prestwick Care Ltd & Ors v Secretary of State for the Home Department [2025] EWCA Civ 184 that the Home Office has no duty to conduct an impact assessment before revoking a sponsor licence, even where revocation will cause widespread disruption to the business, its workforce, or those it serves. As Baker LJ held: “there is no obligation on the SSHD to engage with the impact of revocation on migrant workers and their families, the sponsor’s service users, its business or the wider industry.” Where a mandatory ground is established, the Home Office’s focus is the integrity of the immigration system, and the commercial consequences for the sponsor carry no legal weight in the decision.
Judicial review remains the only route to challenge a revocation decision. A pre-action protocol letter must be sent to the Home Office stating the grounds on which the decision is said to be unlawful. The Home Office typically has 14 days to respond. Grounds that have succeeded include procedural unfairness, where a sponsor was not given a proper opportunity to respond to the concerns before the decision was made, and irrationality, where the factual basis for the finding is demonstrably wrong. An application for judicial review must be filed within three months of the revocation date. Suspension of the revocation requires a separate, urgent injunction, which the court will grant only on strong grounds.
Sponsors who receive a revocation notice have 20 working days to submit representations. That window should be used carefully: acknowledge any genuine breaches, supply documentary evidence to refute any factually incorrect findings, and demonstrate that remedial steps have already been taken. The quality of representations submitted in that period will shape both the Home Office’s response and, if judicial review becomes necessary, the strength of the legal challenge. For detailed guidance on the appeals and compliance visit process, our sponsor licence compliance pages cover the full procedural framework.
Frequently asked questions
Can a sponsor licence be revoked without warning?
Yes, the Home Office can revoke a sponsor licence without a prior warning where a mandatory ground is established. In less serious cases, the Home Office will typically suspend the licence first, giving the sponsor 20 working days to make representations before a final revocation decision is made. Where the breach is serious, for example, where the sponsor has knowingly provided false information or has employed workers illegally, immediate revocation without a suspension period is permitted under the sponsor guidance.
How long is the bar on reapplying after revocation?
The cooling-off period is normally 12 months from the date of revocation. During that period, the sponsor cannot apply for a new licence and cannot sponsor any overseas workers. In any new application submitted after the cooling-off period, the sponsor must explain why the licence was revoked and outline what has changed. The Home Office will scrutinise the new application more closely than an initial one, and refusal rates for post-revocation applications are higher than for first-time applicants.
Does the salary threshold change affect existing sponsored workers?
Yes, the pay-period salary rule, which came into force on 8th April 2026, applies to any worker whose Certificate of Sponsorship was assigned on or after that date. For workers on CoS assigned before 8th April 2026, the previous rules continue to apply for the current permission period, but sponsors should audit arrangements now before any renewal or extension triggers a new CoS. Where a role is on the Immigration Salary List, the relevant going rate for that SOC code still applies and must be met in every pay period from the date the new rule takes effect for that worker.
