Appendix D Sponsor Licence

Appendix D is one of the most critical parts of the UK sponsorship framework for employers. It sets out the detailed record-keeping duties that licensed sponsors must follow to evidence compliance during Home Office monitoring and audits. While the sponsor guidance explains the overall rules and processes of sponsorship, Appendix D (an annex within the sponsor guidance framework) drills into the exact documents and information employers must hold and be able to produce.

What this article is about
This article provides a detailed, legally accurate overview of Appendix D for UK sponsor licence holders. It explains what Appendix D is, why it matters, and the specific records you must keep for your organisation and each sponsored worker. It also clarifies retention periods as set out in the sponsor guidance (including where documents must be kept until examined by a compliance officer), how the Home Office monitors compliance, and the practical steps to make your HR systems audit-ready. By the end, you will understand the documentation standards, retention rules, and best practice needed to protect your licence and mitigate risks, including licence action and potential civil penalties for illegal working where right to work records are deficient.

Section A: What is Appendix D?

1. Definition and role

Appendix D is an annex within the UK sponsor guidance that specifies which documents sponsor licence holders must keep to evidence compliance. It lists the required records for each sponsored worker, as well as corporate records for the organisation. Its role is to ensure a clear audit trail of how and why a migrant worker was sponsored, and that the sponsor has met its duties at all times.

2. Legal purpose

The purpose of Appendix D is to provide the Home Office with a consistent framework for assessing compliance. By setting out detailed documentation requirements, Appendix D helps the Home Office monitor that sponsored workers meet visa conditions, that employers are employing them lawfully, and that sponsors are not misusing the immigration system. Failure to produce these records when requested can be treated as a breach of sponsor duties.

3. Connection to sponsor duties

Appendix D sits alongside wider sponsor obligations, including reporting and right to work checks. The duties are interlinked: for example, a right to work check must be recorded and retained in line with Appendix D. In this way, Appendix D converts general compliance requirements into specific evidential obligations.

Section A Summary
Appendix D is the record-keeping backbone of sponsor compliance. It sets out the evidence sponsors must hold to prove they are meeting their wider duties. A failure to keep these records can be treated as non-compliance, regardless of whether the sponsorship itself was genuine.

Section B: Record-Keeping Requirements

1. Documents for sponsored workers

For every sponsored worker, employers must retain a complete set of records, including:

• A clear copy of the worker’s current passport, including all visa endorsements
• Biometric Residence Permit (BRP) or digital status share code result
• Evidence of right to work checks carried out before employment began
• Contract of employment or engagement letter
• Payslips and bank transfer records showing salary payments
• Absence and annual leave records, including sickness
• Copies of qualifications or professional accreditations relied upon
• National Insurance number, where available

2. Organisational documents

Sponsors must also retain business-level documents to demonstrate they are genuine and compliant, such as:

• Companies House registration details and filings
• HMRC PAYE and VAT registration evidence
• Business bank statements and financial accounts
• Recruitment records (adverts, interview notes, selection criteria, where relevant)
• HR policies covering recruitment, absence and right to work checks

3. Retention periods

The sponsor guidance sets strict retention rules. Records must usually be kept for whichever is shorter of:

• One year from the date sponsorship ends, or
• Until examined by a Home Office compliance officer

Some records, such as right to work checks, must also be kept for the duration of employment. Sponsors should take a cautious approach and never destroy documents before the minimum period has expired.

Section B Summary
Appendix D requires employers to retain detailed records for both sponsored workers and the organisation. These include identity, contract, salary and absence records for workers, and financial and regulatory evidence for the business. Records must be kept for specified retention periods to ensure compliance.

Section C: Compliance and Enforcement

1. Home Office audits

The Home Office can carry out compliance visits, often at short notice. During these inspections, officers will request specific records listed in Appendix D, such as right to work checks, payslips, or absence logs. Missing or incomplete records can be treated as a breach, even if the sponsorship itself was otherwise lawful.

2. Consequences of breach

Failing to comply with Appendix D obligations can result in serious consequences, including:

• Downgrading of the sponsor licence rating from A to B
• Action plans requiring remedial measures
• Suspension of the licence, preventing new Certificates of Sponsorship being issued
• Revocation of the licence, which may force sponsored workers to leave the UK

In addition, missing right to work records may expose employers to civil penalties for illegal working, creating both financial and reputational risks.

3. Best practice

Sponsors should embed Appendix D duties into their everyday HR operations. Good practice includes:

• Collecting and storing all required records during onboarding
• Maintaining clear and secure digital or paper records
• Carrying out regular internal audits to identify and address gaps
• Training HR staff and managers on sponsor duties
• Ensuring records can be produced quickly during an inspection

Section C Summary
Appendix D is the benchmark used during Home Office audits. Non-compliance can result in downgrading, suspension, revocation, or civil penalties. Employers who adopt best practice record-keeping are far better placed to demonstrate compliance and protect their licence.

Section D: Practical Guidance for Employers

1. HR systems

Employers should decide whether to manage records digitally, on paper, or through a hybrid system. Digital files provide accessibility and back-ups, but must meet data protection standards. Paper records can be simple but risk loss or misfiling. Whichever method is chosen, records must be secure, organised, and accessible for Home Office inspection. Access should be restricted to trained HR staff to preserve confidentiality and consistency.

2. Integrating right to work checks

Right to work checks are a fundamental sponsor duty. Appendix D requires that evidence of these checks is retained. Employers should embed this into recruitment and onboarding so that checks are always completed and recorded before employment starts. For digital checks, save a PDF copy of the Home Office online result with the date and share code. For physical documents, keep a clear, dated copy. Storing these directly in HR files reduces duplication and oversight risks.

3. Preparing for audits

Sponsors should prepare as though a Home Office visit could take place at any time. Preparation measures include:

• Carrying out periodic internal audits against Appendix D requirements
• Correcting any gaps promptly and recording remedial actions
• Training all HR and compliance staff on document requirements
• Maintaining an easily accessible “audit file” containing key records

Section D Summary
Employers should build Appendix D duties into HR processes by using secure record systems, integrating right to work checks, and preparing audit files in advance. A proactive approach ensures sponsors can demonstrate compliance if inspected.

FAQs

What is Appendix D for sponsor licence holders?
Appendix D is an annex to the UK sponsor guidance setting out the mandatory records a sponsor licence holder must keep for both their organisation and their sponsored workers. It provides the evidential framework for demonstrating compliance with sponsorship duties.

How long must documents be kept under Appendix D?
Most records must be kept for the duration of the worker’s employment and for at least one year after sponsorship ends, or until a Home Office compliance officer has examined them. Right to work check evidence must be kept for the full duration of employment.

What records are most commonly checked by the Home Office?
During compliance visits, officers usually request to see right to work checks, contracts, payslips, bank transfer records, and absence logs. They may also review organisational documents such as PAYE registration and HR policies.

What happens if I fail to comply with Appendix D?
Failure to keep or produce the required records can be treated as a breach of sponsor duties. This can lead to licence downgrading, suspension, or revocation, and may expose the employer to civil penalties for illegal working.

Do digital copies meet Appendix D requirements?
Yes. Digital copies are acceptable provided they are clear, complete, securely stored, and can be produced promptly on request. Sponsors should ensure that digital systems comply with data protection legislation.

Conclusion

Appendix D is a cornerstone of sponsor licence compliance. It details which documents must be kept, how long they must be retained, and how these link into wider sponsorship duties. Even where sponsored workers meet visa requirements, failure to keep the prescribed records can still result in compliance action.

The Home Office relies on Appendix D when conducting audits and monitoring sponsors. Employers who integrate record-keeping into their HR systems, maintain right to work evidence, and prepare for inspections will be in the best position to demonstrate compliance. By contrast, gaps in documentation place the licence, workforce stability, and business continuity at risk.

Treating Appendix D not as an administrative burden but as a practical compliance tool helps sponsors maintain their licence, safeguard their workforce, and avoid enforcement action or civil penalties.
