Sponsor Licence Compliance Solicitors with offices across Hampshire, Wiltshire and Dorset
Once a business becomes a registered sponsor, it must meet strict compliance duties set by the Home Office. These include detailed record-keeping and reporting requirements, as well as maintaining robust HR systems. Failure to comply can lead to a licence being downgraded, suspended or revoked, putting your ability to employ overseas workers at risk.
At Trethowans, our Immigration team supports employers with every aspect of Sponsor Licence compliance, helping you understand your obligations and maintain strong, audit‑ready systems.
What do Trethowans Sponsor Licence Compliance solicitors do?
A Sponsor Licence places significant responsibilities on businesses. The Home Office can conduct announced or unannounced compliance visits at any time, and sponsors are expected to demonstrate full adherence to their duties throughout the lifetime of the licence.
Record‑keeping duties
Sponsors must retain a wide range of documents, including:
- Evidence relating to the business and the Sponsor Licence
- Key documents for each sponsored worker
- Proof of right to work checks
- Up‑to‑date contact and employment details for sponsored employees
HR systems must be organised, accessible and well maintained so that key documents can be provided immediately during an audit. Staff responsible for managing sponsored workers must understand where documents are stored and what information must be retained.
Reporting duties
Sponsors must report certain changes within strict time limits, including:
- Changes to an employee’s working arrangements or job role
- Absences from work above required thresholds
- Changes to salary, work location or duties
- When a sponsored worker stops attending or leaves employment
- Business‑level changes such as mergers, sales, restructures or TUPE transfers
If reports are not made within the required timeframe, the Home Office may take compliance action, including downgrading or revoking the licence.
Our team advises on all aspects of Sponsor Licence compliance, including:
- Conducting HR audits to review your systems and identify areas for improvement
- Advising on record‑keeping and reporting best practice
- Supporting businesses following a missed reporting deadline
- Preparing for Home Office compliance visits
- Advising on how organisational changes affect the Sponsor Licence
