If your organisation has received a letter from UK Visas and Immigration (UKVI) suspending your sponsor licence, or telling you it has already been revoked, the practical questions are rarely about which rule was broken. They are about what happens next: what your sponsored workers can and cannot do, how long you have to respond, and whether the decision can be challenged at all.
This article explains how a sponsor licence moves from a compliance concern to a suspension or a revocation, what each stage means for the business and its sponsored workers, and what options remain once a final decision has been made. It does not cover how a B-rating and action plan work, which is a separate and more common scenario covered in our companion article on keeping an A-rated sponsor licence, or the mechanics of applying for a licence in the first place.
Key Takeaways
Revocation is final. There is no right of appeal, and the only route of challenge is judicial review.
Revocation grounds fall into three categories, set out in Annexes C1 to C3 of the sponsor guidance: some the Home Office will always act on, some it will normally act on unless there are exceptional circumstances, and some are discretionary.
Home Office guidance no longer requires a breach to be deliberate for a licence to be revoked.
A sponsor given notice of suspension has 20 working days to respond in writing before UKVI makes its final decision.
Sponsored workers not involved in the breach normally have their permission cut to 60 calendar days; those found complicit can lose all remaining permission.
A revoked sponsor cannot reapply for at least 12 months, rising to 24 months for a second revocation.
Why Might a Sponsor Licence Be Suspended or Revoked?
Sponsorship is a privilege, not a right. Home Office guidance states that a sponsor licence is held at the Home Office’s discretion and can be withdrawn at any time, and that significant trust is placed in the organisations it licenses (GOV.UK: sponsor duties and compliance). That framing is why the courts have consistently declined to give sponsors the benefit of the doubt once a breach comes to light.
Where UKVI finds a sponsor is not meeting its duties, it can reduce or remove the sponsor’s ability to assign new Certificates of Sponsorship (CoS), downgrade the licence to a B-rating, suspend it while it investigates, revoke it outright, or refer the matter to the police. These are not sequential steps. A relatively minor, fixable breach normally leads to a downgrade see our companion article, “What Is an A-Rated Sponsor Licence (and How to Keep It)?” [link to be inserted once published]. A more serious breach, particularly where it suggests the sponsor no longer meets the basic eligibility or suitability requirements, more often goes straight to suspension or revocation.
The grounds for revocation sit in three annexes to the sponsor guidance, and which annex a ground falls under determines how much room there is to argue against it.
The most commonly encountered grounds include giving false information on the original application, having no genuine trading presence in the UK, assigning a Certificate of Sponsorship to a role that is not genuine, and paying a sponsored worker less than the salary stated on their CoS without a permitted change. A role that no longer matches the occupation code or job description on the CoS through an unreported promotion or restructure, not only a new hire, is also treated as a mandatory ground.
Home Office guidance is explicit that grounds for revocation “do not necessarily require breaches to be deliberate or made knowingly.” In practice, that means good faith and administrative error are not, on their own, enough to prevent a licence being revoked. Home Office figures show revocations more than doubling year on year, from 937 to 1,948 between July 2024 and June 2025 (GOV.UK: record numbers of visa sponsor licences revoked), and current trends suggest that figure will be exceeded again.
What Happens When a Sponsor Licence Is Suspended?
Suspension is an interim step while UKVI investigates. It is not a lesser penalty , it removes the sponsor from the public register, blocks any new Certificate of Sponsorship, and applies across every route the sponsor is licensed for.
-
No new CoS can be assigned while the suspension is in place
-
The organisation disappears from the public register of licensed sponsors
-
Existing sponsored workers keep their permission and are not affected unless and until the licence is revoked
-
Applications relying on a CoS assigned before the suspension, including settlement applications, are put on hold rather than decided
-
Sponsor duties continue as normal wherein reporting deadlines for worker and organisational changes are not paused
A worker who was granted entry clearance before the suspension can, in principle, still travel and start work, provided the licence has not been revoked by the time they do. That window is narrow and cannot be relied on; anyone in that position should check the public sponsor register before travelling.
How Should You Respond to a Suspension Letter?
On suspension, the licensee receives a letter setting out the evidence relied upon for the decision. This marks the opportunity to request a review and to submit any mitigating representations. A sponsor has 20 working days from the date of the suspension letter to respond in writing, setting out why the grounds are wrong or providing mitigating evidence. There is no oral hearing. If UKVI raises new reasons during that period, it must give a further 20 working days to respond to them, and if no response arrives in time, UKVI proceeds on the basis of what it already has.
Where a breach genuinely occurred, the stronger position is usually to concede it and show, with dates and named steps, what has already been fixed. This follows the test UKVI itself applies paragraph C10.6 of the sponsor guidance states that it “will look for evidence that you have adequate processes and procedures in place and have taken all reasonable steps to verify information you are required to obtain and hold.” Representations that are combative or unsupported by evidence tend not to fare well in practice, though the specific case law on this point should be re-verified before publication.
UKVI will normally give its final decision within 20 working days of receiving the response. The outcome can be reinstatement at A-rating, reinstatement with a B-rating and an action plan, a restriction on assigning or using CoS, or revocation.
What Happens to Sponsored Workers If a Licence Is Revoked?
Revocation is final, and every Certificate of Sponsorship already assigned becomes invalid immediately. Any pending visa application relying on one is refused, and entry clearance already granted but not yet used is cancelled.
For workers already in the UK, the outcome depends on whether they were involved in the reasons for revocation.
UKVI notifies affected workers directly but does not tell them why the licence was revoked. Employers should expect workers to hear from the Home Office before any internal communication reaches them and should plan accordingly. A worker who overstays after their permission is curtailed risks enforcement action and a bar of up to 10 years on future UK applications.
Worked Example: What Revocation Actually Costs
A medium-sized employer sponsors 12 Skilled Workers, each on a three-year Certificate of Sponsorship. Following a compliance visit, the licence is revoked. The Home Office fees already paid are unrecoverable in full or in part, and the business faces a minimum 12-month cooling-off period before it can reapply.
These figures are illustrative. The correct calculation depends on the sponsor’s size classification, the number of workers sponsored, and the length of each CoS.
Can You Appeal a Sponsor Licence Revocation?
No. There is no right of appeal against a decision to revoke a sponsor licence, and no administrative review either. The only route of challenge is judicial review, which must be brought promptly and in any event within three months.
Judicial review does not re-examine the merits of the decision; it asks only whether UKVI acted lawfully, rationally and fairly. The courts have been consistently reluctant to interfere. In R (New London College Ltd) v Secretary of State for the Home Department, the Supreme Court described the sponsor guidance as, in substance, conditions of participation that a sponsor accepts in exchange for the benefits of a licence, rather than obligations imposed on it against its will. Later Court of Appeal decisions have confirmed that the seriousness of the commercial consequences for a sponsor is not, by itself, a reason for the courts to apply closer scrutiny.
Successful challenges do happen, but they tend to turn on process rather than substance and most often where UKVI has, in effect, accused a sponsor of dishonesty without clearly saying so and giving it a fair chance to respond before the decision was made. Where no such procedural flaw exists, a court is unlikely to interfere even where the sponsor considers the outcome disproportionate.
Re-Applying After Revocation: The Cooling-Off Period
A revoked sponsor cannot apply for a new licence until at least 12 months have passed from the date it was notified of the revocation. That period rises to at least 24 months for a second revocation, and longer still in cases involving a civil penalty for illegal working. Surrendering the licence part-way through a compliance investigation does not avoid this and the same cooling-off period applies, running from the date UKVI accepts the surrender.
A fresh application is not simply reassessed on the same terms as any other. The organisation has to demonstrate that it has addressed every reason the previous licence was revoked, and where the revocation involved dishonesty or deliberate misconduct, UKVI expects compelling evidence of that before it will consider a new licence at all. That evidence needs to be built well before the application is filed, not assembled the week it goes in.
Frequently Asked Questions
No. There is no right of appeal or administrative review. The only option is judicial review in the High Court, which must be brought promptly and within three months, and which examines the lawfulness of the decision rather than its merits.
20 working days from the date of the letter. The response must be in writing and supported by evidence; there is no opportunity for an oral hearing.
Workers not involved in the breach normally have their permission cut to 60 calendar days. Workers found to have been knowingly involved can lose all remaining permission and may need to leave immediately.
Yes. Current guidance no longer requires a breach to be deliberate. Poor record-keeping or an unreported change can support revocation even where there was no intention to breach the rules.
Not necessarily. Where a mandatory ground applies, UKVI can revoke immediately without a prior suspension. Suspension is more common where UKVI needs to investigate before deciding.
At least 12 months from the date of the revocation, or 24 months for a second revocation. Longer periods apply in certain civil penalty cases, and any new application must show that every issue behind the original revocation has been resolved.
Not if it happens during compliance action. The same cooling-off period applies, running from the date UKVI accepts the surrender rather than from the date of a formal revocation decision.

Conclusion
A suspension letter is not the end of the story, but the window to change the outcome is short and closes fast. A revoked licence narrows the questions rather than closing them: whether the decision can survive a judicial review challenge, what the cooling-off period means for the workforce, and what has to be rebuilt before a fresh application stands a realistic chance. Neither question is answered well under time pressure, and the quality of the evidence gathered before a response is filed is usually what decides the outcome.
