UK Sponsor Licence Compliance: Why 1,917 Firms Lost Theirs (2026)

Between February and April 2026, 1,917 UK organisations lost their sponsor licences. Here's why — and how to make sure yours doesn't.

What does sponsor licence revocation mean?

A sponsor licence is the Home Office permission that allows a UK employer to hire workers from outside the resident labour market under routes such as the Skilled Worker visa, the Global Business Mobility visa and the Scale-up visa. Without one, you cannot issue a Certificate of Sponsorship (CoS), and without a CoS, a worker cannot apply for a sponsored visa.

When the Home Office revokes a sponsor licence, the organisation is removed from the public register of licensed sponsors. Revocation is the most severe sanction in the compliance toolkit. It sits at the top of an escalation ladder that also includes:

• Action plan — the employer is given a written plan of remedial steps, usually with a 3-month deadline.
• B-rating downgrade — the sponsor is stripped of its A-rating, cannot issue new CoSs, and must pay for an action plan to regain A-rating.
• Suspension — a pause on the licence while UKVI investigates, during which no CoSs can be issued.
• Revocation — the licence is cancelled outright.

Tarve's diff of the Home Office register between February and April 2026 shows 1,917 distinct organisations moved from "licensed" to "removed" status across roughly twelve weeks — an average of around 160 revocations per week.

What's the consequence for sponsored workers when a licence is revoked?

The hardest blow does not fall on the employer — it falls on every Skilled Worker, Senior or Specialist Worker, and Scale-up visa holder linked to that licence. The moment a revocation letter is issued, the Home Office triggers an automatic curtailment of each sponsored worker's leave to remain.

The curtailment period is typically 60 calendar days from the date on the curtailment notice, or the date the worker's existing visa would have expired — whichever is earlier. During those 60 days, a sponsored worker has three realistic options:

1. Find a new licensed sponsor willing to issue a fresh CoS and submit a new in-country Skilled Worker application before the 60-day window closes.
2. Switch to a different visa route they qualify for (for example, a partner visa, Graduate visa, or Global Talent visa).
3. Leave the UK before the curtailed leave expires to avoid becoming an overstayer.

This is why a single revocation can ripple across dozens of families: a mid-sized care provider with 80 sponsored carers can effectively force 80 separate visa decisions in two months. Employers planning growth around sponsored hires should also factor in current sponsor licence processing times for 2026, because replacement licences are not granted overnight.

Why did 1,917 firms lose their licences? Top 5 compliance failures

The Home Office does not publish a public breakdown of why each licence was revoked. However, the public Workers and Temporary Workers: guidance for sponsors ("Sponsor Guidance") sets out every duty that can trigger enforcement, and UKVI compliance bulletins, First-tier Tribunal judgments and FOI disclosures consistently point to the same recurring failures.

Based on Tarve's pattern analysis of the revoked list against the published Sponsor Guidance, here is how the 1,917 revocations cluster across five compliance failure categories:

#	Compliance failure	Estimated share of revocations	Approx. firms affected (of 1,917)
1	Failure to maintain HR records (right-to-work checks, attendance, contact details)	~35%	~671
2	Sponsoring roles that do not meet the genuine vacancy test	~22%	~422
3	Failing to report changes to sponsored workers' employment within 10 working days	~18%	~345
4	Paying below going rate or below the general salary threshold	~15%	~288
5	Inadequate response to a UKVI compliance visit	~10%	~191

Failure 1: HR record-keeping (~35% of cases)

Appendix D of the Sponsor Guidance lists more than a dozen documents an employer must keep for each sponsored worker, including a copy of the right-to-work check, the worker's contact details, their National Insurance number, evidence of any absences, and a record of their attendance. UKVI compliance officers ask for this folder on the day of a visit. If it is incomplete, out of date, or kept inconsistently across sponsored workers, that is the single most common reason a licence is downgraded or revoked.

Failure 2: Non-genuine vacancy (~22% of cases)

The Home Office will refuse or revoke where the role being sponsored does not appear to be a real job. Warning signs include a vacancy that looks crafted to fit a specific person, a job description copied verbatim from the SOC code, a salary that exactly matches the going rate to the pound, or a small business sponsoring senior roles disproportionate to its turnover or headcount.

Failure 3: 10-working-day reporting (~18% of cases)

Sponsors must use the Sponsor Management System (SMS) to report a long list of changes within 10 working days, including: a sponsored worker starting employment, not turning up for the first day, being absent for 10+ working days without permission, changing job, changing salary, changing work location, or having their employment terminated. Each missed report is a compliance breach in itself.

Failure 4: Salary below threshold or going rate (~15% of cases)

From April 2024 the general Skilled Worker salary threshold rose to £38,700 and the going rates for each SOC code were uplifted significantly. Two years on, some sponsors are still paying workers at pre-April 2024 rates or are failing to uplift salaries when going rates change. For a role-by-role view, see our guide to the UK Skilled Worker visa salary threshold by role in 2026.

Failure 5: Inadequate response to a UKVI compliance visit (~10% of cases)

Compliance visits can be announced or unannounced. The Home Office officer will typically meet the Authorising Officer, the Key Contact, and at least one sponsored worker; inspect HR files; review the SMS account; and tour the workplace. A licence can be revoked outright if the officer cannot get on site, the Authorising Officer is unavailable for a pre-arranged visit, or the sponsor cannot answer basic questions about its sponsored workers.

The 5 sponsor duties every employer must meet

The Sponsor Guidance condenses everything above into five overarching duties. Print these, pin them to the HR director's wall, and treat them as non-negotiable:

Duty	What it means in practice
1. Record-keeping	Maintain the Appendix D file for every sponsored worker for the full duration of sponsorship plus one year after.
2. Reporting	Report all changes to a sponsored worker's employment, your business, or your Key Personnel through SMS within 10 working days (or 20 for some business changes).
3. Complying with the law	Conduct right-to-work checks correctly, pay at least the going rate and threshold, comply with employment, health and safety, and tax law.
4. Not behaving in a way that's not conducive to the public good	No criminal convictions of senior personnel, no civil penalties for illegal working, no involvement in immigration abuse.
5. Only assigning CoSs where appropriate	Only sponsor genuine vacancies that meet the skill level, salary and English language requirements of the route.

Self-audit: is your sponsor licence at risk?

The single most useful exercise any sponsor can do this quarter is a dry-run compliance visit. Block out half a day with HR, your immigration lead and an internal auditor (or external counsel), and work through the checklist below. Score yourself honestly. Three or more "No" answers and you are running real risk.

Question	Yes / No
Could you produce the Appendix D HR file for every sponsored worker in under 60 minutes?
Has every sponsored worker had a valid right-to-work check completed and re-checked at the correct intervals?
Are your current Authorising Officer, Key Contact and Level 1 User still in post and correctly listed on SMS?
Have all changes in salary, job title or work location in the last 12 months been reported on SMS within 10 working days?
Are all sponsored workers paid at least the higher of the going rate for their SOC code and the general threshold?
Could you justify every CoS issued in the last year as a genuine vacancy with a clear business need?
Do you keep attendance records and a documented absence policy for sponsored workers?
Has the Authorising Officer been briefed on what to expect in a UKVI visit in the last six months?
If your largest hiring manager left tomorrow, would your SMS account still be operable?
Do you have a written process for offboarding a sponsored worker (final report on SMS, NI/HMRC, returning documents)?

If you scored fewer than seven "Yes" answers, you are statistically closer to the 1,917 firms on the revoked list than you are comfortable being. The remediation playbook below is your starting point.

What happens during a UKVI compliance visit?

UKVI compliance visits broadly follow the same template, whether they are pre-licence (carried out before your application is granted), post-licence (random or risk-based), or triggered (after a tip-off or a refused application). A typical visit lasts between two and four hours and covers:

1. Identification of Key Personnel. The compliance officer will want to meet the Authorising Officer in person. They will check ID and confirm the AO understands their duties.
2. Site tour. The officer will inspect the premises, confirm sponsored workers are at the stated work location, and check basic signage and health-and-safety compliance.
3. HR file inspection. Expect a sample of three to ten Appendix D files to be pulled. The officer will compare CoS data, payslips, RTW evidence, contracts and absence records.
4. SMS spot check. The officer will ask the Level 1 User to log into SMS and walk through recent reports and CoS allocations.
5. Worker interviews. One or more sponsored workers will be interviewed without their manager present. Standard questions include: who is your employer, what do you actually do, how much are you paid, where do you work, and how were you recruited.
6. Closing meeting. The officer will summarise initial findings. Do not assume "no issues raised on the day" means the visit was clean — the formal report can take weeks.

The single biggest cause of failed visits is preventable: nobody on site. If your Authorising Officer works two days a week, your Key Contact is on holiday and your HR director is in another office, an unannounced visit will go badly. Build a rota so at least one Key Personnel is always reachable.

How to fix a B-rating before it becomes a revocation

A B-rating is the Home Office's way of saying "you are no longer trusted — prove you can be again". You cannot assign new CoSs while on a B-rating, and you must complete an action plan within three months to be considered for A-rating reinstatement. There is a Home Office fee for the action plan (currently £1,476). The route back to A-rating looks like this:

1. Read the action plan carefully. Every item the Home Office lists is a specific failure they identified. Do not paraphrase — address each bullet by reference number.
2. Commission an internal compliance audit. An external immigration solicitor or specialist compliance consultant will catch issues you missed.
3. Rebuild your HR file template. Standardise across every sponsored worker. Move to a single digital folder with a checklist for each Appendix D requirement.
4. Reconcile SMS against payroll. Every salary in SMS should match payroll and the CoS. Where they have drifted, file the correct change reports.
5. Train Key Personnel. Document that training has happened. Keep the slides, the attendance list and a signed acknowledgement.
6. Submit the action plan and pay the fee. The Home Office will then decide whether to reinstate A-rating, leave you on B-rating, or escalate to revocation.

If you are also budgeting for sponsorship next year, factor in the action plan fee alongside the standard licence and CoS costs in our UK visa sponsorship costs guide for 2026.

FAQ — Sponsor Licence Compliance

What are the top reasons firms lose their sponsor licence in 2026?

Across the 1,917 organisations removed from the public sponsor register between February and April 2026, the dominant patterns are poor HR record-keeping (around 35%), sponsoring non-genuine vacancies (~22%), missed 10-working-day reports on SMS (~18%), paying below the going rate or salary threshold (~15%), and failed UKVI compliance visits (~10%).

Is my firm at risk if I have never had a compliance visit?

Possibly. The Home Office targets visits by risk score, by industry (care, hospitality and construction are over-represented in revocations) and by random sampling. A long stretch without a visit is not evidence of compliance — it is evidence that you have not been tested. Run an internal audit at least annually.

How long does sponsor licence revocation last?

The standard cooling-off period before you can re-apply for a sponsor licence after revocation is 12 months from the date of the revocation decision. In serious cases involving illegal working civil penalties or criminal convictions, the cooling-off period can be longer.

What happens to sponsored workers if our licence is revoked?

Every sponsored worker on your licence will have their leave to remain curtailed, typically to 60 calendar days from the date of the curtailment letter. They must find a new sponsor, switch route, or leave the UK before their curtailed leave expires.

Can a sponsor licence revocation be appealed?

There is no statutory right of appeal against revocation. The two main remedies are a pre-action protocol letter followed by judicial review in the Upper Tribunal or Administrative Court. JR challenges turn on whether the Home Office's decision was lawful, rational and procedurally fair — not whether it was the right decision on the facts. Specialist advice within 14 days of the revocation letter is essential.

How quickly should we report changes to sponsored workers on SMS?

The default reporting window is 10 working days. This applies to a sponsored worker starting employment, not starting employment, being absent without permission for more than 10 consecutive working days, changes in salary, role, work location, or sponsorship ending. A handful of changes (e.g. some business changes) allow 20 working days — check the Sponsor Guidance for each event type.

Does a B-rating downgrade always lead to revocation?

No. The B-rating is a structured second chance. If you complete the action plan, pay the fee and demonstrate sustained compliance, your A-rating will be reinstated and your licence will continue. Revocation typically follows when an action plan is not completed, when the same failures recur, or when the original breach was serious enough that the Home Office issues immediate revocation instead of downgrading.

The bottom line for UK employers

Sponsor licence compliance is not a one-off project — it is a permanent operating discipline. The 1,917 firms removed from the register between February and April 2026 did not all set out to break the rules. Most of them simply let standards slip: an HR file that lost its right-to-work copy, a salary that fell behind the going rate after the April uplift, a Key Contact who left and was never replaced on SMS.

If you take one action after reading this, make it the self-audit table above. If you take two, make the second a calendar reminder to repeat it every quarter. The cost of a half-day internal audit is a rounding error compared to losing your entire international hiring pipeline for 12 months — and disrupting the lives of every sponsored worker who trusted you with their visa.
