Sponsor Licence Suspended: The 20-Day Window and What to Do First

Key Takeaways

• You have 20 working days from the date on the suspension letter to respond in writing. Paragraph C9.11 of the Home Office's Part 3 sponsor guidance (version 08/26, valid from 28 August 2026) sets the deadline, and it confirms there is no oral hearing, so the written response is the whole of your case.
• More time is given only in exceptional circumstances, so plan as if you will get none. Paragraph C9.12 allows an extension only where the Home Office is satisfied the circumstances are exceptional. A further 20 working days arises only if the Home Office adds new reasons for the suspension (C9.13).
• If you do not respond, the Home Office decides without you. That is paragraph C9.15. In R (J's Supermarket Ltd) v SSHD [2026] EWCA Civ 1147, handed down on 4 September 2026, a suspension letter dated 22 August 2024 went unanswered while the director was abroad. The licence was revoked on 10 October 2024 and the Court of Appeal upheld the revocation.
• Answer every allegation separately, because one surviving ground can be enough to revoke. In the linked Prestige Social Care appeal, the court agreed that one of the Home Office's grounds was unlawful. The sponsor still lost, because two other grounds under Annex C2 stood on their own and section 31(2A) of the Senior Courts Act 1981 required the court to refuse relief.
• Do four things first: diary the deadline, keep meeting every sponsor duty, preserve your records and map each allegation to its Annex C ground. Paragraph C9.2 says your sponsor duties continue in full throughout the suspension, and a new breach during the 20 working days can become a new reason against you.
• The Home Office must tell you the gist of its case and give you a fair chance to answer it. In R (Moon Fish Ltd) v SSHD [2026] EWHC 2289 (Admin), also handed down on 4 September 2026, the High Court quashed a revocation for procedural unfairness and held that even a "mandatory" Annex C1 ground leaves a residual discretion not to revoke. The decision was sent back to the Home Office to be taken again. The court did not restore the licence.
• The Home Office does not have to weigh the damage revocation would do to your business. The Court of Appeal decided that in R (Prestwick Care Ltd) v SSHD [2025] EWCA Civ 184 on 11 March 2025. It may consider the impact if you raise it, so the place to raise it, with evidence, is in your representations.
• Suspension ends in one of three ways: reinstatement with an A-rating, a B-rating with an action plan, or revocation. The Home Office aims to decide within 20 working days of receiving your response (C9.17). There is no right of appeal against revocation (C9.5). The only challenge is a pre-action protocol letter followed by judicial review.
• Your existing sponsored workers keep their permission during a suspension, but you cannot assign any Certificate of Sponsorship. Paragraphs C9.4 and C9.19 say so. Visa and settlement applications that depend on your licence are put on hold until the suspension is resolved (C9.20).
• WPC Lawyers prepares suspension representations and, as a solicitors' firm, can conduct a judicial review if a licence is revoked. See our sponsor licence suspension and revocation service for how we handle the response from the day the letter arrives.

Introduction

A sponsor licence suspension letter starts a clock. From the date on that letter you have 20 working days to put your case to the Home Office in writing, and what you send in that period is, in practice, the only case the decision-maker will ever read. There is no hearing, no meeting as of right and no appeal if the licence is then revoked.

This post is about that one letter. It sets out what the current guidance says about the deadline, what to do in the first few days, how to build written representations that deal with every allegation, and what the courts have said the Home Office owes you in return. It draws on two judgments handed down on the same day, 4 September 2026, and on the Court of Appeal's 2025 decision in Prestwick Care.

Everything here is confirmed law or published Home Office guidance as at 2 October 2026. The guidance is Part 3: Sponsor duties and compliance, version 08/26, valid from 28 August 2026 (an accessible HTML copy was added on 2 September 2026). It replaced version 05/26 and sits within the Home Office's sponsorship guidance collection. There are no proposals, consultations or Bills in this post. Where the case law is unsettled, we say so in terms, in the section headed "Where the law is unsettled".

We do not cover why licences are suspended or how to avoid it. Our sister firm WorkPermitCloud has done that in Why UK sponsor licences are suspended in 2026 and how to protect yours. This post begins where that one ends, with the letter already in your hand.

The Deadline: 20 Working Days From the Date of the Letter

The rules on timing are short and they are all in section C9 of Part 3. You have 20 working days from the date of the written notification to respond. The period runs from the date on the letter, not from the day you opened it or the day it reached the right person.

How to count the days

The sponsor guidance glossary defines a working day as any day other than a Saturday, a Sunday or a UK bank holiday. As an illustration, a letter dated Thursday 1 October 2026 would give a last day of Thursday 29 October 2026, counting Friday 2 October as day one. The guidance does not spell out whether the date of the letter itself counts, so if your letter states a response date, work to that date. If it does not, use the earlier of the two possible readings.

Suspension letters and decisions are sent by Royal Mail Signed For or by email (C9.18). A letter emailed to an Authorising Officer who is on leave is still a letter served, and the days still run.

Extensions and the fresh 20 days

The guidance does not define exceptional circumstances, and nothing in it suggests that workload, a busy period or the time needed to gather records will qualify. If you need more time, ask early, in writing, explain exactly what prevents a full response and attach proof. Keep preparing as though the request will be refused, because the original deadline continues to apply until the Home Office says otherwise.

The second 20 working days in paragraph C9.13 is not an extension. It arises only when the Home Office identifies additional reasons for the suspension during the first period, for example from interviews with your sponsored workers, and it is a period for answering those additional reasons.

One practical caution. Paragraph numbers in section C9 have shifted between versions of the guidance. The judgments discussed below quote earlier versions, in which the "no response" rule was C9.14 and the list of outcomes was C9.15. The substance is the same. Cite the version in force on the date of your letter.

What to Do First, in Order

The first week matters more than the last. The four steps below come before any drafting.

On step 3, what you are required to hold is set out in Appendix D to the sponsor guidance. Our sister site WPC HR explains it in Appendix D explained: getting your sponsor records audit ready. For the purposes of a suspension response the point is narrower: find what exists, keep it intact and be candid about what does not exist.

Mapping allegations to Annex C

Annexes C1, C2 and C3 to Part 3 list the circumstances in which the Home Office will, will normally, or may revoke a licence. Paragraphs C9.7, C9.8 and C10.5 to C10.7 explain how each is treated. The distinction shapes what your response has to achieve.

Suspension letters often rely on a mandatory ground and several Annex C2 grounds at once. It is tempting to spend the whole response on the most serious allegation. The Prestige appeal, below, shows why that is a mistake.

How to Build the Representations

Paragraph C9.11 tells you what the Home Office expects: a written response that sets out, with relevant supporting evidence, which grounds you believe to be incorrect and why, together with any mitigating arguments. A general letter of explanation does not meet that description. A response that follows the structure of the suspension letter does.

Answer every allegation separately

Take the allegations one at a time, in the order the Home Office has used. For each one, state whether you accept or dispute the facts, say why, and refer to a numbered document that proves it. Then say whether, on those facts, the Annex ground is made out. Do not merge two allegations into one answer, and do not leave any allegation without a reply because it looks minor.

The reason is the second appeal decided in J's Supermarket, brought by Prestige Social Care Services Ltd. Prestige was a care provider whose licence was suspended on 26 March 2024 and revoked on 15 October 2024. The Home Office relied on Annex C1(z), alleging that a role was not genuine because the worker recruited to a driving role could not drive, and separately on Annex C2(a) and (b), citing poor recruitment practice and staff turnover of at least 40 per cent against a care sector average of 28.3 per cent.

The courts agreed with Prestige that the Annex C1(z) finding was unlawful. A recruitment error did not show that the job did not exist, and the allegation had been withdrawn and then revived in the decision letter without warning (paragraphs 75 and 77). Prestige still lost. The decision letter had said that each ground was, individually, a basis for revocation. The Court of Appeal held that it was highly likely the licence would have been revoked under Annex C2(a) and (b) in any event (paragraphs 81 to 84).

That result follows from section 31(2A) of the Senior Courts Act 1981. It provides that the High Court must refuse relief in a judicial review claim if it appears highly likely that the outcome for the applicant would not have been substantially different had the conduct complained of not occurred. The threshold is a high one, and the court stressed that there will be many cases where it cannot be met (paragraphs 60, 61 and 84). But where a decision rests on several independent grounds, defeating one of them is not enough. The representations are your opportunity to answer all of them, and each unanswered ground is one that may later hold the decision up.

Use evidence that can be traced to its source

Assertion is not evidence. In J's Supermarket the Court of Appeal accepted that the Home Office was entitled to take account of the fact that no job description had been provided when requested, to place no reliance on WhatsApp screenshots that could not be attributed to anyone, and to disregard photographs that did not show what duties the workers actually performed (paragraph 67). There were no records showing that the two workers had ever carried out the managerial roles on their CoS (paragraph 71).

The practical lesson is to prefer documents that were created at the time, that identify who made them and that speak directly to the allegation: signed contracts and job descriptions, payslips matched to bank payments, rotas, system logs, dated emails. Witness statements from the director and from the workers concerned belong in the response too. In the Supporting Care case, heard together with Prestwick, the High Court judge took the view that the sponsor's eight witness statements ought to have been sent with its response to the suspension letter and not produced for the first time in the judicial review. The Court of Appeal records that finding at paragraph 72 of its judgment.

Deal with any suggestion of dishonesty head on

Some allegations carry an implication of deliberate conduct, typically that a role was "created" or "exaggerated" to facilitate a worker's stay. In Prestwick Care the Court of Appeal held that a mismatch between a CoS job description and the work actually done may justify suspicion but does not by itself prove dishonesty. It calls for an explanation (paragraph 132). The Home Office must indicate its suspicion clearly, consider your explanation and give reasons if it then infers dishonesty (paragraphs 134 to 136).

If your letter contains wording of that kind, give the explanation expressly and support it. If no explanation is offered, the same passage of Prestwick accepts that the Home Office may legitimately draw the inference.

Put mitigation and impact in writing

Mitigation is not an admission. A response can dispute a ground and also say, in the alternative, why revocation would be the wrong outcome if the ground is upheld. That alternative case should cover how serious the breach really is, whether it was isolated or systemic, what caused it, what has been corrected since and whether a B-rating with an action plan would address the concern.

It should also cover the consequences of revocation for your workforce, the people who rely on your services and the business itself, with evidence rather than general statements. The Court of Appeal held in Prestwick that "mitigating arguments" in paragraph C9.11 extends beyond the circumstances of the breach to broader arguments about the consequences of revocation (paragraph 114). Prestwick had said nothing about impact in its response and could not complain afterwards that the Home Office had not asked.

What Silence Costs

The J's Supermarket appeal is the clearest recent example of what happens when the 20 working days pass without a response.

J's Supermarket ran a grocery business in Tooting with about ten staff and had held a sponsor licence since 16 January 2023. After a compliance visit on 9 May 2024, the Home Office suspended the licence by a letter dated 22 August 2024. The letter set out the duties on two workers' CoS, one a retail manager and one a shopkeeper, alongside what each worker had told the compliance officer he actually did, which was shop floor work. It gave 20 days to respond.

The director had travelled abroad for the school holidays, had difficulties with a SIM card and did not see the letter on his return. No response was sent. The licence was revoked on 10 October 2024 under Annex C1(z) and several Annex C2 grounds (paragraphs 18 and 19).

Solicitors then sent a pre-action protocol letter on 26 October 2024 with witness statements. The Home Office agreed to reconsider and, on 12 November 2024, upheld the revocation. The High Court dismissed the judicial review claim on 25 July 2025 and the Court of Appeal dismissed the appeal on 4 September 2026. The court held that the suspension letter had fairly set out the Home Office's concerns, and that the sponsor had been given a proper opportunity to answer them (paragraphs 64 and 71).

Two points follow. First, an explanation for missing the deadline, however understandable, did not change the outcome. Second, material sent after the decision was considered, but it was considered by a decision-maker who had already revoked. The courts have recognised more than once that representations made after a decision are a weaker safeguard than representations made before it, because a decision-maker may, in good faith, tend to defend a conclusion already reached. That reasoning comes from Balajigari v SSHD [2019] EWCA Civ 673 and is quoted in Prestwick at paragraph 32.

What Fairness the Home Office Owes You

The obligations do not run one way. A sponsor licence is described in the guidance as a privilege and not a right, but the decision to remove it is still a public law decision and must be made lawfully. Three judgments mark out the current position.

Moon Fish: the gist of the case and a chance to answer it

Moon Fish was not a suspension case. On 20 October 2025 the Home Office asked the sponsor for payroll documents, referring in general terms to Annex C1(aa). The sponsor supplied them on 3 November 2025 without comment. On 18 November 2025 the Home Office revoked the licence with immediate effect, because the records showed that one worker had been paid less than his CoS salary in two months. Nobody had asked why. The reason, given only afterwards in a pre-action letter, was a period of agreed unpaid compassionate leave that the sponsor had failed to report.

The deputy judge held that the duty of procedural fairness is not displaced by the sponsorship scheme. The Home Office must normally give fair warning of the gist of its concerns and a reasonable opportunity to make representations, even where it believes a mandatory ground is made out and even where no dishonesty is alleged (paragraph 128). A general request for documents was not enough. He also held that the Home Office had misread Annex C1(aa), which in his judgment does not cover unreported unpaid leave that is otherwise permitted (paragraphs 71 and 143).

On discretion, the judge held that the "mandatory" label is not the end of the matter. A residual discretion not to revoke exists even where an Annex C1 ground is established, the Home Office had accepted as much, and the seriousness of the breach is relevant to how it is exercised (paragraphs 59 to 65). Because of that, a sponsor should generally have the chance to be heard on seriousness as well as on the facts.

For a suspended sponsor the most relevant sentence is in paragraph 128. Where the suspension route has been used, the judge said the process in section C9 will generally be a sufficient opportunity to respond, so long as the suspension letter set out the charges adequately. In other words, the suspension process is usually the fair hearing. If your letter is too vague to answer, say so in the response, identify what is unclear and ask for particulars, while still answering as fully as you can.

Moon Fish needs to be read for what it is. The court quashed the decision and sent it back to the Home Office to be taken again. It did not decide that the sponsor should keep its licence, and it left the assessment of the admitted reporting breach, and any sanction for it, to the Home Office (paragraphs 151 and 174). A successful judicial review of this kind produces a fresh decision, which may or may not be a different one.

Prestwick: no duty to weigh the impact on your business

Prestwick Care operated 15 care homes and, at the date of revocation, employed 857 staff of whom 219 were sponsored. It argued that the Home Office had to assess what revocation would do to the business, its residents and local social care before deciding. The Court of Appeal rejected that. The question for the Home Office is the effect of the breach on the integrity of immigration control, not the consequences of removing the licence (paragraph 97). Impact is something the decision-maker may take into account and may rationally give no weight (paragraphs 101 to 103).

The court also held that a sponsor is not entitled to a heightened standard of fairness or to greater protections than the guidance provides (paragraph 112). In the linked Supporting Care appeal, however, it upheld the quashing of a revocation because an allegation of deliberate exaggeration had not been put clearly before the decision (paragraphs 137 to 139).

Where the law is unsettled

It would be wrong to present these cases as a settled code. Four points remain open, and a careful response is drafted with each of them in mind.

• How far fairness goes beyond the guidance. Prestwick says a sponsor is not entitled to greater protections than the guidance provides. Moon Fish reads that statement as confined to cases where the suspension process was actually used, and holds that common law fairness fills the gap where the Home Office revokes directly. Moon Fish is a first-instance decision. The Court of Appeal's judgment in J's Supermarket was handed down the same day and does not consider it.
• When the residual discretion must be addressed. The discretion exists, but Prestwick (paragraph 100) confirms that the Home Office need not give reasons for declining to exercise it unless the sponsor has given it a particular reason to do so. That is a further reason to set out your case on seriousness in writing.
• When one unlawful ground brings down the whole decision. In Prestige it did not. In Moon Fish it did, because the court could not say revocation was highly likely on the remaining breach. In Supporting Care the point was not argued. The answer turns on how the decision letter is worded and how strong the remaining grounds are.
• What counts as an adequately particularised suspension letter. J's Supermarket found a letter that set CoS duties against interview answers to be sufficient. There is no fixed test, and the courts have said repeatedly that what fairness requires depends on context.

None of this alters the practical position during the 20 working days. Fairness arguments are for a court, later, and only if needed. The response itself should be written on the assumption that the Home Office will apply its guidance strictly.

The Three Outcomes, and What Follows a Revocation

Paragraph C9.16 lists the action the Home Office may take once it has considered your response, or once the time for responding has passed. In practice there are three outcomes, sometimes combined with restrictions on your CoS.

The action plan fee is set in the Home Office fees table. Action plans themselves are a subject for a later post alongside our sponsor compliance advice service.

No right of appeal: the pre-action letter and judicial review

Because there is no appeal, the only way to challenge a revocation is judicial review in the Administrative Court. The court does not rehear the merits. It asks whether the decision was lawful, rational and procedurally fair. The first step is a letter before claim under the Pre-Action Protocol for Judicial Review. The Protocol records that a claim must be filed promptly and in any event not later than three months after the grounds arose, and that sending a letter does not extend that limit.

Conducting litigation and exercising rights of audience are reserved legal activities under section 12 of the Legal Services Act 2007, which is why a judicial review claim is conducted by a solicitors' firm, or other authorised person, and not by an unregulated adviser. We deal with that work through our immigration appeals and judicial review and challenging refusals services, and the procedure, time limits and costs will be covered in a separate post.

For present purposes the point is this. A judicial review tests the decision the Home Office made on the material it had. The strongest foundation for any later challenge is therefore a complete, evidenced response filed within the 20 working days.

Your Sponsored Workers and CoS During the Suspension

A suspension does not, by itself, change the immigration status of the people you already sponsor. It does stop new sponsorship.

Workers can check the register of licensed sponsors and will see that your name is missing. It is usually better that they hear the reason from you. Tell them accurately what a suspension is and is not, and bear in mind that the Home Office may interview them (C9.13). You should not rehearse or script their answers.

Because no CoS can be assigned, a sponsored worker whose permission is due to expire during the suspension cannot be given a CoS for an extension until the licence is reinstated. Identify anyone in that position in the first week. If the licence is later revoked, the consequences for workers are different and more serious. Our sister firm WorkPermitCloud covers them in Can skilled workers continue working during the 60-day curtailment period?

How Can WPC Lawyers Help?

Our sponsor licence suspension and revocation team reviews the suspension letter, confirms the deadline, maps each allegation to the ground it relies on, and prepares written representations with an indexed evidence bundle and witness statements. Where a licence has already been revoked, we advise on whether there are grounds for a pre-action protocol letter and, as a firm of solicitors, we can conduct a judicial review claim. We cannot promise any particular outcome, and we will tell you plainly where an allegation is difficult to answer.

This work sits within our wider business immigration services. Our fixed fees for suspension representations, pre-action letters and judicial review are published on our fees page.

Conclusion

A suspension letter gives you 20 working days, counted from its date, to make your whole case in writing. The guidance allows more time only exceptionally, offers no hearing and provides no appeal. The September 2026 judgments show both sides of that. A sponsor that does not answer, or answers only part of the case against it, is unlikely to be rescued by a court afterwards. A sponsor that was never told the case against it has a real argument that the decision was unfair.

The work in the window is methodical: fix the deadline, keep complying, secure the records, identify the ground behind each allegation and answer each one with evidence, then set out why revocation would not be the right response even if a breach is found. Done properly, that gives the Home Office what it needs to reinstate the licence if the facts support it, and it preserves your position if they decide otherwise.
