The Complete Guide to Sponsor Licence Compliance in 2026
Everything UK employers need to know about maintaining their sponsor licence. From legal obligations and Appendix D requirements to surviving Home Office audits—this comprehensive guide covers all six compliance domains and gives you practical steps to stay audit-ready year-round.
Holding a sponsor licence is a privilege, not a right. The Home Office expects every sponsor to maintain robust systems that ensure compliance with immigration law. In 2025, compliance visits increased by 252%, civil penalties reached record highs, and more licences were revoked than ever before.
This guide is designed for Authorising Officers, Key Contacts, HR professionals, and anyone responsible for managing sponsored workers in the UK. Whether you're new to sponsorship or looking to strengthen existing processes, you'll find practical, actionable guidance based on the latest Home Office requirements and enforcement priorities.
Who This Guide Is For
- • Authorising Officers responsible for sponsor licences
- • Key Contacts who manage day-to-day compliance
- • HR managers and people operations teams
- • Business owners who sponsor skilled workers
- • Compliance and legal teams in sponsored organisations
What Is Sponsor Licence Compliance?
Sponsor licence compliance refers to meeting all the legal duties and responsibilities that come with holding a licence to sponsor migrant workers. When the Home Office grants your organisation a sponsor licence, you enter into a formal agreement to follow specific rules—and those rules are detailed in the Immigration Rules and Appendix D (the sponsor guidance document).
Compliance is not a one-time activity. It's an ongoing commitment that requires:
- Record-keeping: Maintaining specific documents for each sponsored worker
- Reporting: Notifying the Home Office of certain changes within strict deadlines
- Monitoring: Tracking attendance, absence, and immigration status
- Cooperating: Allowing Home Office visits and responding to requests for information
The Legal Basis
Your obligations come from the Immigration Act 1971 (as amended), the Immigration Rules, and specifically Appendix D—the sponsor guidance. These documents set out exactly what you must do and what happens if you don't.
Key Personnel
Every sponsor licence has an Authorising Officer (who takes overall responsibility) and at least one Key Contact (who handles day-to-day management). A Level 1 User manages the Sponsor Management System (SMS).
Your Legal Obligations as a Sponsor
The Home Office groups your duties into four main categories. Understanding each category is essential for maintaining compliance.
Record-Keeping Duties
You must keep specific documents for each sponsored worker and be able to produce them within one working day if requested by the Home Office.
Key Requirements:
- Keep copies of identity documents, visas, and Right to Work evidence
- Maintain employment records matching Certificate of Sponsorship details
- Retain records for the duration of employment plus 2 years after leaving
- Store documents securely with audit trail of access
Reporting Duties (The 10-Day Rule)
Certain events must be reported to the Home Office through the Sponsor Management System (SMS) within strict deadlines—typically 10 or 20 working days.
Key Requirements:
- Worker does not start employment on expected date
- Worker is absent from work without permission for 10+ consecutive working days
- Worker's employment ends (for any reason)
- Significant change to worker's job (title, duties, salary reduction)
Compliance Duties
You must ensure sponsored workers are only doing the job they were sponsored for, at the location and salary specified on their Certificate of Sponsorship.
Key Requirements:
- Ensure work matches Certificate of Sponsorship details
- Monitor visa expiry dates and immigration status
- Track attendance and identify unexplained absences
- Cooperate with Home Office visits and requests
Appendix D: Required Documents
Appendix D lists the documents you MUST keep for every sponsored worker. Failure to produce these during an audit is one of the most common reasons for licence revocation.
Identity & Immigration
- Copy of passport (photo page and any pages with visa or entry stamps)
- Copy of current immigration permission (visa or eVisa confirmation)

What is a sponsor licence and who needs one?
A sponsor licence is official permission from the Home Office that allows UK employers to hire workers from outside the UK on work visas. Any UK business wanting to employ someone who requires a Skilled Worker visa, Health and Care Worker visa, or similar work visa category must hold a valid sponsor licence. This includes companies of all sizes, from small startups to large corporations, as well as public sector organisations and charities.
How long does it take to get a sponsor licence?
The standard processing time for a sponsor licence application is up to 8 weeks, though many applications are processed faster. You can pay for a priority service that aims to process applications within 10 working days. Processing times can vary based on the complexity of your application and how quickly you respond to any Home Office requests for additional information.
What is the difference between A-rated and B-rated sponsor licences?
An A-rating means you are fully compliant and can continue sponsoring workers. A B-rating means the Home Office has identified compliance issues that need addressing. With a B-rating, you cannot sponsor new workers and must follow an action plan to regain your A-rating within 3 months. Failure to do so can result in licence revocation. Most licences are downgraded to B-rating following a compliance visit where issues were found.
What documents must I keep for each sponsored worker?
Under Appendix D of the Immigration Rules, you must keep: copies of passports and visas, right to work evidence with dates and verification methods, the Certificate of Sponsorship and assignment details, employment contracts showing job title and salary, evidence of salary payments, current contact details including home address and phone number, absence and attendance records, and recruitment records showing how you hired the worker. All documents must be kept for the duration of employment plus 2 years after the worker leaves.
What changes must be reported to the Home Office within 10 working days?
You must report within 10 working days: if the worker does not start their job, stops working for you, or is absent without permission for more than 10 consecutive working days. You must also report changes to their job (including job title, salary reduction, or core duties), changes to their work location, if they stop studying (for student work placements), or if there are any issues with their immigration status. Reports are made through the Sponsor Management System (SMS).
