UK Sponsor Guidance Appendix D: Complete Employer Record Keeping Guide

What is Appendix D Compliance in the UK?

Appendix D is a core annex to the main Home Office sponsor guidance. It details the exact document categories, acceptable formats, and evidence files employers must keep to fulfill their statutory duties. Maintaining appendix d compliance in the UK proves that your organization sponsors genuine workers, pays eligible salaries, and tracks employment activity lawfully.  

Why UK Visas and Immigration (UKVI) Audits Sponsor Records

UKVI conducts both announced and unannounced audits to ensure sponsors do not abuse the immigration system. During an inspection, compliance officers review Appendix D files to verify that:

• The sponsored employee holds valid right-to-work status.  
• The position filled reflects a genuine operational need.
• The salary paid matches or exceeds the mandatory threshold set out in the Certificate of Sponsorship (CoS).

Core UK Visa Sponsor Duties Under the Latest Guidance

Holding a sponsor licence comes with four primary responsibilities set out by the Home Office:

1. Record Keeping: Retaining mandatory identification, recruitment, and pay documents under Appendix D.  
2. Reporting Duties: Notifying UKVI via the Sponsor Management System (SMS) within 10 working days of key changes (e.g., salary updates, location changes, or unauthorized absences).  
3. Monitoring & Compliance: Ensuring sponsored workers maintain valid immigration status and tracking attendance.  
4. General Compliance: Adhering to broader UK employment law, including National Minimum Wage standards and Working Time Regulations.  

Record-keeping is only one of four duties; the full picture of reporting, monitoring and enforcement is covered in our guide to UK sponsor licence compliance duties and penalties.

What Documents Does Appendix D Require? (The Mandatory Checklist)

1. Right to Work Proof and Identity Records

Every sponsored employee file must start with clear proof of identity and legal right to work.  

Navigating the eVisa Transition for UK Employers

With the Home Office transition to a fully digital immigration system, physical Biometric Residence Permits (BRPs) and entry vignettes are fully phased out. Sponsors must perform digital Right to Work checks using the Home Office online service:  

• Generate and request a Share Code from the applicant.
• Run the check on the official GOV.UK "Check a job applicant's right to work" tool.  
• Retain a clear PDF or printout copy of the online check outcome showing the worker’s photograph and expiry date.

Documenting National Insurance Numbers and Passport Copies

• Passport Copies: Retain copies of current passport ID pages, including personal details, photo, and expiry dates.  
• National Insurance (NI) Number: Keep documented proof of the worker's NI number via official documentation such as a P45/P60, HMRC letter, or itemized payslip.  

2.Recruitment Evidence: Eligible Role vs Genuine Vacancy UK Standards

To prevent illegal working and job market inflation, sponsors must prove that every sponsored position is valid.  

Proving Skill Levels and Job Descriptions

You must retain formal proof that the employee possesses the required qualifications or experience for the SOC code assigned. This includes degree certificates, professional licences (e.g., GMC/GDC registration for medical personnel), or written references from past employers.  

Standardized Advertising and Selection Evidence

Even where a formal Resident Labour Market Test (RLMT) is not mandatory, keeping recruitment evidence demonstrates genuine selection. Retain:

• Copies or screenshots of job advertisements placed showing location and duration.  
• Shortlists, interview scoring rubrics, and notes explaining candidate selection.

The March 2026 shift from "Genuine Vacancy" to the broader "Eligible Role" test is explained in our UK Certificate of Sponsorship: HR's complete 2026 guide.

3. Payroll and Salary Threshold Documentation

Salary compliance is verified per pay period. Sponsors must ensure earnings meet CoS specifications without unauthorized deductions.  

Payslips, Contracts, and Bank Transfer Records

• Employment Contracts: Signed employment contracts detailing job title, working hours, and gross salary.  
• Itemized Payslips: Monthly or weekly payslips displaying NI numbers, tax deductions, and gross pay.
• Proof of Payment: Business bank account transfer statements verifying that net salary was transferred directly to the worker.

4. Worker Contact Details and Attendance Monitoring Logs

• Up-to-Date Contact Info: History of the worker's current UK residential address, personal mobile number, and personal email address.  
• Absence Management: Absences must be logged. Retain annual leave logs, sickness reporting forms, and records of any unauthorized absences exceeding 10 consecutive working days.  

Summary of the four sponsor duties, the four document categories, retention rules, and the red flags that trigger licence action

Document Retention Rules: How Long to Keep Right to Work Documents in the UK

The Standard Rule: Duration of Sponsorship Plus One Year

The primary rule governing how long to keep right to work documents in the UK under Appendix D is:

• Duration of sponsorship PLUS at least one year; OR
• Until a UKVI compliance officer has examined and approved the files (if this occurs sooner after sponsorship ends).  

Exceptions for Compliance Audits and Historical Records

Certain documents require alternative retention periods:

• International Sportsperson Endorsements: Retained for 2 years after endorsement expiration.  
• General Statutory RTW Records: Standard employment law requires basic RTW proof to be held for 2 years after employment ends to preserve statutory excuses against civil penalties.

Secure Digital Storage vs Physical Document Archiving (UK GDPR Compliance)

UKVI permits both digital and physical file formats, provided records are legible and quickly accessible. However, sponsors must balance Appendix D accessibility with UK GDPR and Data Protection Act 2018 requirements:  

• Use encrypted, role-restricted digital HR drives.
• Avoid keeping personal data longer than the statutory period unless legally required.

Preparing for Audit: Your UKVI Compliance Audit Checklist

Step-by-Step Mock Audit for HR Teams

Conducting periodic internal reviews ensures your team remains audit-ready:

1. Check CoS Matching: Audit active CoS records against actual duties performed.
2. Verify RTW Status: Ensure online share code checks were completed before employment start dates.  
3. Cross-Reference Salary: Verify payslips confirm earnings meet CoS rate thresholds.  
4. Audit Contact Logs: Promptly update missing addresses or phone numbers.  

Reporting Changes via the Sponsor Management System (SMS)

Always record and report the following changes on the SMS within 10 working days:  

• Changes in work location or hybrid working arrangements.
• Salary adjustments (e.g., unpaid leave or maternity leave updates).  
• Early termination of employment or failure to start the role.

Every reportable change must be logged on the UK Sponsor Licence Management Service (SMS), and knowing who can do this matters.

Common Appendix D Red Flags That Cause Licence Suspension or Revocation

• Failure to produce requested records during an unannounced UKVI inspection.  
• Missing proof of recruitment or inability to prove a genuine vacancy.
• RTW checks completed after the employee began work.
• Outdated contact information or unmonitored worker absences.  

Best Practices for Maintaining Appendix D Compliance

Onboarding Checklists and Automated HR Workflows

• Integrate mandatory Appendix D document capture into standard onboarding workflows.
• Issue formal employee rights statements and retain signed worker acknowledgments.
• Set automated calendar alerts for visa expirations and scheduled Right to Work re-checks.

How to Rectify Missing Documents Before an Audit

If a internal audit reveals missing documents:

• Conduct a fresh online Right to Work check immediately.  
• Obtain historic payroll and bank transfer records from accounting departments.
• Document the discrepancy internally and append a file note explaining the corrective actions taken.
