Home Office compliance visits can occur before a licence is granted or at any time afterwards, announced or unannounced. Strong systems and accurate records are the best defence.

Sponsor compliance is enforced through Home Office compliance visits, which can take place both before a licence is granted (pre-licence) and at any point after (post-licence). Visits may be announced or unannounced, and may be conducted in person at the sponsor's premises or as a "desktop" digital audit. Officers typically attend for around two to three hours and examine right to work compliance, record-keeping under Appendix D of the sponsor guidance, whether vacancies are genuine and match the Certificate of Sponsorship, whether changes have been reported through the Sponsorship Management System within the required 10 working days, and broader compliance with UK employment law. The possible outcomes are significant: a licence can be maintained at A-rating, downgraded to B-rating (which prevents the assignment of new CoS until upgraded), suspended pending investigation, or revoked. Separately, civil penalties for illegal working can reach up to £45,000 per worker for a first breach and up to £60,000 for repeat breaches. Preparation is the difference between a clean outcome and significant business disruption.
Appendix D of the sponsor guidance lists the documents sponsors must keep for each sponsored worker, including right to work evidence, contact details, attendance records and contracts. Map every category to a named owner and storage location, and check that records are complete, current and easily retrievable. Missing or stale records are the single most common compliance failing.
Sample a cross-section of sponsored and non-sponsored workers and re-perform the right to work check end to end against current Home Office guidance. Confirm the correct method was used, that records bear a check date pre-dating employment, and that follow-up dates are diarised. Where gaps are found, address them and document the remediation.
Many changes — including changes of address, role, salary, working pattern and absences — must be reported via the Sponsorship Management System (SMS) within 10 working days. Review the last 12 months of HR changes against SMS activity to identify any missed or late reports. Late reporting cannot always be undone, but a self-correction recorded in good faith is better than waiting for a visit.
Officers may interview the Authorising Officer, Key Contact, Level 1 User and line managers, as well as sponsored workers. Brief each on what their role involves, the genuineness of the relevant vacancies, the recruitment process, and how SMS reporting and right to work checks operate. Inconsistent or vague answers can themselves trigger further action.
Officers will compare the role described on the CoS against what the worker actually does, the worker's qualifications, the salary paid, and the wider business need. Ensure job descriptions, organisation charts, payroll records and the CoS narrative tell a consistent story. Any drift since the CoS was assigned should be reportable and supportable.
Have a written process for receiving officers on site: a named contact, access to a meeting room with a screen, a printed Appendix D index, copies of the licence and current CoS records, and the contact details of your immigration adviser. A calm, organised reception sets the tone for the rest of the visit.
Yes. Both pre-licence and post-licence visits can be announced or unannounced, and can be in-person or carried out as a desktop digital audit. Sponsors should assume an unannounced visit is possible at any reasonable time and have systems in place accordingly.
Most visits take in the region of two to three hours, although complex cases or larger sponsors can take longer. Officers may follow up after the visit with further document requests before issuing a written outcome.
A licence can be maintained at A-rating, downgraded to B-rating, suspended pending investigation, or revoked. A B-rating prevents new CoS being assigned until an action plan is completed and the licence upgraded; civil penalties for illegal working can be issued separately.
Sponsors must keep the documents listed in Appendix D of the sponsor guidance for each sponsored worker, plus evidence of HR systems for recruitment, right to work, monitoring and reporting. Records must be retrievable promptly for officers and, for right to work checks, retained for two years after employment ends.
