Sponsor Licence Compliance 2026: Duties, Risks, and Remedies

Overview

Holding a UK sponsor licence is not a one-off achievement. It is an ongoing compliance obligation that requires active management, regular reporting, and up-to-date HR systems. The Home Office has made this increasingly clear, and the consequences of falling short have become significantly more severe.

This guide explains what compliance involves in practice, what the Home Office expects from licence holders, and what has changed following the significant guidance update published on 6 March 2026. Whether you already hold a licence or are preparing to apply for one, understanding these duties is essential.

What Changed on 6 March 2026

The Home Office published updated sponsor guidance (version 03/26) on 6 March 2026, introducing changes that affect every licence holder. These updates reflect a broader shift toward stricter enforcement and reduced tolerance for compliance failures.

The "Eligible Role" Replaces "Genuine Vacancy"

The concept of a "genuine vacancy" has been replaced with a broader "eligible role" requirement. Under the new definition, an eligible role must:

• Actually exist (or be reasonably expected to exist) at the time the Certificate of Sponsorship is assigned
• Require the worker to perform the specific duties, hours, and responsibilities described on the CoS
• Meet all relevant skill level and salary thresholds, including National Minimum Wage and Working Time Regulations
• Be appropriate to the organisation's business model, plan, and scale
• Continue to meet all of these requirements throughout the duration of sponsorship

This is a wider test than the one it replaces. The genuine vacancy requirement was route-specific, while the eligible role test applies across all sponsored immigration routes. Working in a role that does not match the occupation code or job description on the CoS is now an explicit mandatory ground for licence revocation.

Lower Threshold for Compliance Action

The updated guidance states that the Home Office can now take action based on "reasonable suspicion" of non-compliance. Previously, the standard was closer to requiring proof of a breach. This means the Home Office can refuse a licence application, or revoke an existing licence, where it reasonably suspects that a sponsor is unsuitable or has breached its duties.

The guidance also makes clear that breaches do not need to be deliberate or made knowingly to lead to revocation.

New Worker Rights and Welfare Duty

Sponsors must now ensure that sponsored workers are informed about their employment rights in the UK, and must retain evidence that this information was provided. This is a new explicit obligation, though it builds on the existing expectation that sponsors comply with wider UK employment law.

Salary Compliance Per Pay Period

Sponsored workers must now be paid at least the minimum salary threshold in each pay period, rather than having their salary averaged over a full year. The Home Office can now detect underpayment earlier by cross-referencing PAYE data shared by HMRC.

Sponsorship Framed as a "Privilege"

New language in the guidance describes sponsorship as "voluntary membership" subject to strict terms, and states that a licence can be terminated at the Home Office's discretion at any time. This framing reinforces that maintaining a licence depends on continuous compliance, not just meeting the requirements at the point of application.

Your Core Sponsor Duties

Every licence holder has four categories of ongoing duty. These are set out in Part 3 of the sponsor guidance and apply for as long as you hold your licence.

1. Record Keeping

You must maintain specific documents for each sponsored worker, as listed in Appendix D of the sponsor guidance. These include:

• A copy of the worker's passport and current immigration permission
• A record of the right to work check, including the date it was carried out and who performed it
• The worker's contact details, including current UK address and phone number
• Their employment contract and any amendments
• Payslips or salary records for each pay period
• A history of any absences

Records can be kept in paper or electronic form, but must be accessible for inspection and retained for the duration of sponsorship plus one year after sponsorship ends. All records must comply with UK data protection law.

2. Reporting Changes via the SMS

The Sponsor Management System (SMS) is the Home Office's online portal for managing your licence. You must report specific changes through the SMS within strict deadlines.

Report within 10 working days:

• A sponsored worker does not start their role on the date specified in the CoS
• A worker is absent for more than 10 consecutive working days without permission
• Termination of employment (resignation, dismissal, or redundancy) before the CoS end date
• Changes to the worker's job title, core duties, salary, or work location
• Changes to the size or charitable status of your business

Report within 20 working days:

• A change of business name or any branch name
• A change of address for the main business or any branch
• Mergers, acquisitions, or other changes to company structure
• Changes to key personnel (Authorising Officer, Key Contact, Level 1 User)

Late reporting is one of the most common compliance failures. The Home Office treats missed deadlines seriously, regardless of whether the delay was intentional.

3. Monitoring Sponsored Workers

You must actively monitor your sponsored workers throughout their employment. This includes ensuring they are working in the role described on their CoS, being paid the salary stated, and maintaining their immigration permission. If a worker's circumstances change, you are expected to identify this and take appropriate action, including reporting through the SMS.

The Home Office expects monitoring to be embedded into standard HR processes, not managed as a standalone function. Inconsistency across departments or sites is frequently cited as evidence that compliance depends on individual knowledge rather than organisational control.

4. Complying with Wider UK Law

Sponsors must comply with UK employment law, including National Minimum Wage, Working Time Regulations, and anti-discrimination legislation. Since March 2026, this also includes the explicit duty to inform sponsored workers of their employment rights and retain evidence that you have done so.

A failure to meet these obligations can result in compliance action against your licence, even if the failure is not directly related to immigration.

Key Personnel and Their Responsibilities

Your licence requires you to appoint specific individuals with defined roles. These roles carry personal accountability and must be taken seriously.

The Authorising Officer is the most senior person responsible for sponsorship compliance. They must understand the guidance and are accountable for the actions of all SMS users. The Key Contact is the Home Office's main point of communication. The Level 1 User handles day-to-day SMS operations, including assigning Certificates of Sponsorship, reporting changes, and maintaining records.

All key personnel must be based in the UK, with no relevant unspent criminal convictions. The March 2026 guidance now states that all people included in the definition of "you" in the guidance (owners, directors, AO, Key Contact, Level 1 User, Persons with Significant Control) should read, understand, and keep up to date with the guidance.

When key personnel change, this must be updated in the SMS within 20 working days.

Home Office Compliance Checks

The Home Office conducts compliance checks in several ways, and you should be prepared for all of them.

Unannounced Visits

Compliance officers may visit your premises without prior notice. They will check your HR systems, recruitment practices, SMS records, right to work documentation, and whether sponsored workers are performing the roles described on their Certificates of Sponsorship. They may interview the Authorising Officer or other staff.

Digital Audits

The Home Office now conducts compliance audits digitally, using data shared by HMRC and Companies House. These can take place without the sponsor being contacted or even aware that an audit is happening. PAYE records are cross-referenced with CoS salary declarations, and company financial data is compared against the number and cost of sponsored workers.

This data sharing has been a major driver of the increase in revocations, as discrepancies between declared salaries and actual payments are now identified automatically.

Document Requests

The Home Office may contact you by email to request specific records and information. These requests typically come with strict deadlines and must be treated as urgent.

What Happens When Things Go Wrong

The consequences of non-compliance follow a clear escalation path, though the Home Office can skip steps in serious cases.

B-Rating Downgrade

If the Home Office identifies compliance failures that are not severe enough for immediate revocation, your licence may be downgraded from an A-rating to a B-rating. This means:

• You cannot assign new Certificates of Sponsorship or sponsor new workers
• You must follow a time-limited action plan (typically three months) to address the failures
• If you pass the action plan, your A-rating is restored
• If you fail, the Home Office will move to revocation

Suspension

For more serious concerns, your licence may be suspended pending investigation. During suspension, you cannot sponsor new workers, but existing sponsored workers can continue working. The Home Office will give you 20 working days to make representations.

Revocation

Revocation is the most serious outcome. When a licence is revoked:

• You immediately lose the ability to sponsor any workers
• All existing Certificates of Sponsorship are cancelled
• Sponsored workers receive curtailment notices, typically giving them 60 days to find a new sponsor or leave the UK
• You cannot reapply for a licence for at least 12 months (longer in some cases)
• There is no right of appeal, though you can challenge revocation by judicial review

Civil Penalties for Illegal Working

Separately from licence action, employers who are found to have employed someone without the right to work face civil penalties of £45,000 per illegal worker for a first breach, and £60,000 for a repeat breach within three years. For sponsor licence holders, receiving a civil penalty will usually lead to licence revocation.

Criminal prosecution is possible where an employer knowingly employed an illegal worker, with penalties including up to five years' imprisonment and an unlimited fine.

Common Compliance Failures

Based on recent enforcement trends, these are the areas where sponsors most frequently fall short:

Role and SOC code mismatches. This is the leading cause of revocation. If a worker's actual day-to-day duties do not match the occupation code and job description on their CoS, this is a mandatory ground for licence revocation under the March 2026 guidance.

Late or missing SMS reports. Failing to report changes within the required 10 or 20 working day deadlines. Many sponsors have no internal system for flagging when reports are due.

Salary discrepancies. The salary on the CoS must match what you actually pay. With HMRC data now shared with the Home Office, any gap between declared and actual earnings is detectable.

Incomplete right to work records. Missing or incorrectly conducted right to work checks, or a failure to transition from physical BRP checks to the online eVisa verification system.

Poor HR systems. Compliance managed informally, with no documented processes. The Home Office looks for evidence that sponsor duties are embedded in organisational systems, not dependent on individual knowledge.

Failing to inform workers of employment rights. A new requirement since March 2026, and one that many sponsors have not yet integrated into their onboarding processes.

Sectors Under Increased Scrutiny

While all sponsors face compliance obligations, the Home Office has focused enforcement resources on specific sectors. Health and social care has received the most attention, particularly following the closure of the care worker route to new overseas recruitment in July 2025.

However, analysis of revocation data shows that two-thirds of licence revocations between 2022 and 2025 were outside the health and social care sector. Construction, hospitality, retail, and food services have all seen significant enforcement activity. Sponsors in any sector should not assume they are below the Home Office's radar.

Practical Steps to Protect Your Licence

These are actions you can take now to strengthen your compliance position:

Audit your current sponsored workers. Check that every worker's actual role, salary, and working hours match what is recorded on their CoS. Fix any discrepancies and report changes through the SMS.

Review your key personnel. Ensure your Authorising Officer, Key Contact, and Level 1 User are all current, UK-based, and aware of their responsibilities. Update the SMS if any have changed.

Set up internal reporting triggers. Build SMS reporting deadlines into your HR systems so changes are reported within 10 or 20 working days automatically, not when someone remembers.

Transition to eVisa verification. If you are still relying on physical BRP cards for right to work checks, move to the Home Office online checking service immediately.

Document your worker rights process. Create a standard onboarding step where new sponsored workers receive information about their UK employment rights, and retain signed acknowledgement.

Conduct an internal audit. Review your Appendix D document files, SMS activity logs, and payroll records against CoS declarations. Address gaps before the Home Office finds them.

Stay current with guidance changes. The Home Office updates sponsor guidance at least twice per year. Subscribe to alerts or work with an immigration adviser who monitors changes on your behalf.

How AssessNow Can Help

Before taking on sponsor licence compliance responsibilities, it is worth confirming that your business meets the eligibility requirements. Our Sponsor Licence Eligibility assessment checks your business against the key criteria the Home Office uses when assessing licence applications, including legal suitability, financial viability, and document readiness.

If you are considering applying for a licence, or want to understand your compliance position before a renewal or audit, the assessment gives you a clear picture of where you stand and what you need to address.

For formal compliance advice and audit support, we recommend consulting a specialist immigration solicitor or adviser regulated by the SRA or IAA.
