A Sponsor Licence is not just permission to hire overseas workers. It is an ongoing compliance responsibility. Once your organisation is licensed, the Home Office expects you to monitor sponsored workers, keep accurate records, report changes on time and carry out proper right to work checks.
This matters because sponsorship is treated as a privilege, not an automatic right. The Home Office guidance says licensed sponsors must comply with immigration law, wider UK law and the duties set out in the sponsor guidance. A breach can lead to a downgrade, suspension or revocation of your licence.
For employers, the consequences can be serious. You may lose the ability to sponsor new workers, existing sponsored staff may be affected, and your business may face operational disruption. If your licence is already at risk, taking early advice from suspended sponsor licence solicitors can help you understand the allegations, prepare evidence and respond within the required timeframe.
Sponsor compliance is especially important in the current immigration climate. GOV.UK figures show there were 33,100 Skilled Worker visa applications from main applicants in the year ending April 2026, a 40% decrease compared with the year ending April 2025. The same update linked recent falls in work visa applications to policy changes and increased scrutiny in some sectors.
Why Sponsor Licence compliance should be treated as a business risk
If your organisation relies on sponsored workers, compliance should not sit in the background. It should be part of your HR, payroll, recruitment and management systems.
A weak system can create problems even when the original visa application was genuine. For example, you may have correctly sponsored a Skilled Worker, but later fail to report a change in work location, keep salary evidence or update the worker’s contact details. Those issues may look minor internally, but they can become serious during a Home Office compliance visit.
Compliance also affects commercial planning. If your licence is suspended, you may be unable to assign new Certificates of Sponsorship while the Home Office investigates. If it is revoked, sponsored workers may lose the basis of their permission, and your ability to recruit internationally can be severely damaged.
Your main Sponsor Licence duties
The Home Office guidance identifies key sponsor duties, including reporting duties, record-keeping duties, compliance with immigration law, compliance with wider UK law and avoiding conduct that is not conducive to the public good.
In practical terms, you should be able to show that you know:
- who your sponsored workers are
- where they work
- what role they are doing
- what they are paid
- whether their work matches their Certificate of Sponsorship
- whether their immigration permission allows them to do the work
- whether key changes have been reported to the Home Office
- whether required documents are complete, current and easy to access
These duties start from the day your licence is granted and usually continue until the licence is surrendered, made dormant or revoked. Your responsibility for each sponsored worker starts when you assign their Certificate of Sponsorship and continues until one of the relevant ending events applies, such as the worker’s permission expiring or you reporting that you have stopped sponsoring them.
Reporting duties: what you must tell the Home Office
Reporting duties are usually managed through the Sponsorship Management System. You should not wait until an annual review or internal audit to update the Home Office. Certain worker changes must be reported quickly.
The sponsor guidance says changes to a sponsored worker’s circumstances must generally be reported no later than 10 working days after the relevant change or event. This can include situations where the worker does not start work, stops work, changes their normal work location or is absent without permission for more than 10 consecutive working days.
You must also report certain organisational changes. These can include changes to your business address, trading status, ownership, structure, insolvency position, key personnel or organisation size. Some organisational changes must be reported within 20 working days, and failure to report them can lead to downgrade or revocation action.
Common reporting mistakes include:
- failing to report that a sponsored worker has left employment
- not reporting a permanent change in work location
- forgetting to update key personnel details
- not reporting a merger, takeover or restructuring event
- delaying reports because responsibility is unclear internally
- assuming hybrid or remote working never needs to be reviewed
Remote working deserves particular care. The guidance confirms that day-to-day changes may not need to be reported, but if a sponsored worker is or will be working entirely remotely, with little or no requirement to attend your premises or a client site, you must report this through the SMS.
Record keeping duties: what you should keep on file
Record keeping is one of the most common areas where employers fall short. The Home Office does not simply expect you to have documents somewhere in the business. You should be able to locate them quickly, show they are accurate and demonstrate that they match the role and sponsorship details.
Appendix D of the sponsor guidance sets out the records sponsors must keep. It covers evidence of right to work, recruitment, salary, skill level and additional worker information. The guidance also says sponsor records may be kept in paper or electronic form, provided the relevant parts are visible and accessible.
Unless the guidance says otherwise, documents relating to a sponsored worker must usually be kept throughout the period you sponsor them and until the earlier of 1 year after sponsorship ends or the date a compliance officer has examined and approved them.
Your files should usually include:
- right to work check evidence
- proof of the worker’s date of entry to the UK where relevant
- employment contract or written statement of particulars
- job description and duties
- salary evidence, including payslips and payment records
- evidence of recruitment or how the worker was identified
- qualification, registration or accreditation evidence where required
- National Insurance number evidence where relevant
- a history of the worker’s UK address, email address and telephone number
- absence records
The guidance specifically requires a history of the worker’s contact details, including their UK residential address, personal email address and telephone number, and says this must always be kept up to date.
Right to work checks: why they are still essential
Sponsoring a worker does not remove your right to work responsibilities. You still need to carry out the correct checks before employment begins and, where required, repeat checks before permission expires.
The employer’s guide to right to work checks states that if you employ someone illegally and have not carried out the prescribed checks, you may face a civil penalty of up to £60,000 per illegal worker. Serious cases can also lead to criminal prosecution, business closure orders, director disqualification and loss of the ability to sponsor migrants.
For sponsored workers, right to work checks should match the immigration route, start date and work conditions. You should check that the person is allowed to do the role, not just that they have some form of permission in the UK.
Common problems include:
- not completing the check before work starts
- using expired or incomplete evidence
- failing to use the correct online checking process where required
- not retaining evidence of the check
- not recording the date the check was completed
- missing follow-up checks for time-limited permission
Right to work checks should also be handled consistently across your workforce. A good system helps you avoid both immigration breaches and unfair treatment of workers.
What can trigger a Home Office compliance concern?
Compliance action may arise from a planned visit, a pre-licence check, a post-licence audit, worker complaints, data matching, payroll concerns or information from another public body.
Warning signs can include:
- salary payments that do not match the Certificate of Sponsorship
- workers doing different duties from the sponsored role
- missing HR files
- poor absence records
- unreported work location changes
- unclear reporting responsibility
- business changes that were not reported
- key personnel who do not understand sponsor duties
A compliance issue does not always mean deliberate wrongdoing. Many employers make mistakes because systems have not kept pace with growth, staff changes or remote working arrangements. However, the Home Office may still treat weak systems seriously if they create a risk of immigration abuse.
How to reduce the risk of suspension or revocation
You should treat sponsor compliance as an ongoing process, not an emergency task. The best time to fix weaknesses is before the Home Office asks questions.
A practical compliance plan should include:
- regular internal audits of sponsored worker files
- clear responsibility for SMS reporting
- training for HR, payroll and line managers
- calendar reminders for visa expiry dates and follow-up checks
- salary checks against Certificates of Sponsorship
- work location reviews for hybrid and remote workers
- document checklists for every sponsored worker
- board-level awareness where sponsorship is critical to staffing
You should also record decisions clearly. If you decide a change does not need reporting, keep a note explaining why. If a worker’s duties change, review whether the new duties remain consistent with the sponsored role before making the change permanent.
What to do if your Sponsor Licence is suspended
If your licence is suspended, do not ignore the letter or respond with general assurances. You need to understand each allegation, compare it against your records and provide focused evidence.
You should act quickly by:
- reviewing the suspension letter carefully
- securing all relevant HR, payroll and SMS records
- checking every sponsored worker file
- identifying whether any allegation is factually incorrect
- correcting any ongoing compliance weakness where possible
- preparing a detailed written response with supporting evidence
- taking legal advice before submitting your response
A well-prepared response should be evidence-led. It should explain what happened, correct misunderstandings, accept and address genuine weaknesses where appropriate, and show what steps have been taken to prevent recurrence.
