Sponsor Compliance Audit — Identify Every Risk and Protect Your UK Sponsor Licence
A sponsor compliance audit is a comprehensive review of a UK employer's adherence to Home Office sponsor duties. Sponsor ComplIANS conducts audit-grade assessments that cover every obligation a sponsor licence holder must meet, from record-keeping and right-to-work checks to recruitment practices, salary compliance, and change reporting. The goal is to identify every compliance gap, score the risk level, and deliver a clear, prioritised action plan before the Home Office conducts its own compliance visit.
Our audit methodology has been developed from findings across more than 100 real UK sponsor licence audits. It covers 12 compliance areas, identifies 16 distinct issue types, and has produced a 100% compliance visit pass rate for every client we have prepared.
Why Our Audit Finds What Others Miss
Most compliance consultants review your HR folder and give you a checklist. We review every document, for every sponsored worker, across every compliance area the Home Office assesses — because that is exactly what the Home Office does. Our audit methodology was built from real enforcement cases, real revocation letters, and real compliance visits. It is not based on generic guidance — it is based on what actually gets licences revoked.
65 Documents Per Worker. Not 10. Not 20. Sixty-Five.
Generic audits check a handful of documents — typically contracts, right-to-work copies, and maybe a payslip. Our audit checks 65 document types per sponsored worker, coded SW001 through SW065. These cover immigration monitoring, contact records, recruitment evidence, migrant tracking, reporting duties, the full qualification and skills framework (including all 17 Care Certificate modules), and compliance declarations. For a client with 120 sponsored workers, that meant our team manually reviewed 7,200 individual documents.
12 Compliance Areas. Not Just Pay and Hours.
The Home Office does not just check whether you paid the right salary. They audit across 12 distinct areas: pay and hours, record keeping, right to work, genuine vacancy, recruitment practices, HR systems, reporting duties, immigration status monitoring, key personnel responsibilities, third-party labour, qualifications and skills, and change control. A single weakness in one area cascades into breaches in others. Our audit covers all 12 — because a single missed area is how licences get revoked.
We Audit the Way the Home Office Audits.
The Home Office now uses a two-phase enforcement model. Phase 1 (The Money Stage) analyses payslips, RTI submissions, P60s, and bank statements to verify salary compliance. Phase 2 (The Records Stage) examines your files, contracts, right-to-work checks, job descriptions, training logs, and HR systems during an on-site visit. Our audit simulates both phases — so you know exactly what they will find before they find it.
Your Three-Stage Visa Monitoring — Tested.
One of the first things the Home Office checks is whether you are proactively monitoring visa expiry dates. Our framework includes a three-stage alert system: calendar reminders and formal letters sent at 60 days, 30 days, and 15 days before each sponsored worker's visa expires (documents SW004–SW009). During our audit, we check whether this system exists, whether it has been followed for every worker, and whether the evidence is on file. Most sponsors have nothing. Our clients have a documented, timestamped monitoring trail.
27 QSE Documents — The Area That Destroys Licences.
The Southcroft Healthcare case proved that getting qualifications wrong leads to mandatory revocation — 97 Certificates of Sponsorship with the wrong SOC code destroyed a care empire. Our audit checks 27 qualification, skills, and experience documents per worker (SW037–SW063): the QSE checklist, induction records, all 17 Care Certificate modules, medication competency, shadowing feedback, sign-off letters, completion certificates, spot checks, supervision records, and appraisals. If a worker cannot demonstrate they hold the skills stated on their CoS, your licence is at risk. We find that gap before the Home Office does.

What a Sponsor Compliance Audit Covers
A thorough sponsor compliance audit reviews the following areas:
Record-Keeping Duties
Whether the employer maintains all documents required by the Home Office for each sponsored worker, including contracts, right-to-work evidence, absence records, salary records, and CoS documentation.
HR and Operational Systems
Whether the employer has functioning systems for tracking visa expiry dates, monitoring working hours, managing absence, and triggering compliance alerts.
Ongoing Compliance Readiness
Whether the employer can demonstrate to an inspector that all sponsor duties are being met at the point of a visit, including access to up-to-date files and trained personnel.
Certificate of Sponsorship Management
Whether each CoS has been issued correctly, with the right SOC code, accurate salary details, and proper justification.
Genuine Vacancy and Recruitment Process
Whether the employer can evidence that each sponsored role is a genuine vacancy, filled through a fair, documented recruitment process.
Pay and National Minimum Wage Compliance
Whether each sponsored worker is being paid at or above the published salary threshold for their SOC code and is not being underpaid relative to settled workers in equivalent roles.
Right-to-Work Checks
Whether initial and follow-up right-to-work checks have been conducted correctly, documented, and stored accessibly.
Monitoring and Reporting Duties
Whether the employer has reported all required changes to the Home Office within 10 working days, including absences, resignations, salary changes, and role modifications.
Job Role and Salary Matching
Whether each worker's actual job duties, location, and salary match what was stated on the Certificate of Sponsorship.
Key Personnel Responsibilities
Whether the Authorising Officer, Key Contact, and Level 1 Users understand and are fulfilling their specific compliance responsibilities.
Absence Tracking and Leave Management
Whether the employer monitors and records absences accurately and reports unauthorised absences of 10 or more working days.
Change Control Procedures
Whether the employer has a process for reporting and managing changes to the business, its structure, or its sponsored workers.
10 Most Common Reasons Sponsor Licences Are Revoked
Based on Sponsor ComplIANS's analysis of over 100 UK sponsor compliance audits, the most common reasons for licence revocation are:
Missing or invalid right-to-work checks
The most fundamental duty, frequently overlooked or improperly documented.
Underpaying sponsored workers
Salaries below the minimum threshold for the relevant SOC code.
Non-compliant working hours
Contracted hours not reflecting actual working patterns.
Improper CoS assignment
Certificates of Sponsorship issued to relatives or without genuine business need.
Workers lacking required skills or qualifications
Sponsored employees who do not meet the role's stated requirements.
Non-genuine recruitment practices
Roles that appear fabricated or processes that cannot demonstrate merit-based selection.
Hiring out sponsored workers to third parties
Placing workers at other sites without proper contractual arrangements.
Failure to report changes within 10 working days
Missed notifications for absences, resignations, or salary changes.
Poor record-keeping
Missing contracts, absence logs, pay records, or CoS documentation.
Inadequate HR systems and training
No structured processes for key personnel to fulfil compliance responsibilities.
Our Three-Step Audit Process
Discover
We conduct a full review of your sponsor operations, including HR files, recruitment records, CoS assignments, salary evidence, right-to-work documentation, and reporting compliance. Every area is assessed against the latest Home Office Worker and Temporary Worker guidance.
Diagnose
We produce a detailed compliance report that maps each identified breach to the specific sponsor duty it violates, categorises it by severity (critical, high, medium, low), and explains the consequences of non-remediation. The report includes a compliance risk score and a visual heatmap of your exposure.
Demonstrate
We deliver a tailored action plan with step-by-step remediation, implement the required systems and templates, and train your Authorising Officer and key personnel to maintain compliance independently. The goal is to build a compliance infrastructure that lasts, not a one-off fix.
