Sponsor licence terminology in 2025 can feel like a maze of acronyms, roles, and ratings that only immigration lawyers seem to speak fluently. Yet if you’re running a business that employs Skilled Workers, you can’t afford to get lost in the jargon. From Certificates of Sponsorship to compliance visits, every term carries real-world consequences for how smoothly your licence runs—and whether your business stays in the Home Office’s good books. The article unpacks the essentials in everyday language, showing why each role, status, and acronym matters, and helping sponsors stay confident, compliant, and in control.
An introduction
Understanding your sponsor licence obligations in 2025 begins with knowing the language of sponsorship. Here’s your handy sponsor licence glossary—the essential terms every sponsor should understand:
1. Certificate of Sponsorship (CoS)
A CoS is a digital authorisation issued via the Sponsorship Management System (SMS) to allow an individual to apply for a UK work visa. Think of it as an official “ticket” you provide to a prospective employee. Once assigned, the applicant must use it within three months, and must not apply more than three months before their job start date.
- Defined CoS: Used for overseas applicants applying for entry clearance. Requires prior approval and is tightly controlled.
- Undefined CoS: For workers applying from within the UK on most routes. Simply assigned and used, with no pre-approval needed.
Why it matters: Assigning the wrong type can result in compliance breaches and potential licence revocation.
2. Authorising Officer (AO)
The Authorising Officer is the individual legally responsible for the use of your sponsor licence. They act as the “face” of the licence, ensuring accurate record-keeping and that CoS assignments are legitimate.
Why it matters: Mismanagement by the AO can trigger compliance reviews or even licence suspension.
3. Key Contact (KC)
The Key Contact serves as the primary liaison with UKVI. They handle routine communication, deal with queries, and provide updates on licence matters.
Why it matters: Efficient communication streamlines guidance, deadlines, and compliance responses.
4. Level 1 & Level 2 Users
These are SMS account access levels:
- Level 1 Users: Have full SMS control — apply for and assign CoS, add staff.
- Level 2 Users: More restricted — typically assist with day-to-day tasks without full administrative privileges.
Why it matters: You must always have at least one Level 1 User active; losing access can freeze your operations.
5. A-rated / B-rated Sponsor Status
After evaluation, UKVI assigns:
- A-rating: Indicates a compliant, trusted sponsor.
- B-rating: Imposes restrictions—e.g., you may lose the ability to assign new CoS until you remediate issues.
Why it matters: Only A-rated sponsors may assign CoS on most routes; a B-rating limits your ability to sponsor legally.
6. Compliance Visits
UKVI conducts compliance visits to validate that licence holders comply with sponsorship duties. These can be physical inspections of premises or digital assessments. Officers will review CoS assignments, worker roles, record-keeping, and interview staff or sponsored workers.
Why it matters: These visits protect the integrity of the system. Non-compliance carries serious consequences—including licence suspension or revocation.
Why Each Term Matters in Licence Management?
Understanding these terms isn’t just academic—it’s operational. Your compliance hinges on precision:
- Assigning the correct CoS type avoids breaches.
- Clear delegation among AO, KC, and Level 1/2 Users ensures accountability and continuity.
- Maintaining an A-rating grants full functionality; a B-rating caps your sponsor capabilities.
- Compliance visits test your systems regularly; being prepared with documents, policies, and staff knowledge is essential.
