When a UK employer offers you a role requiring Skilled Worker visa sponsorship, their ability to employ you legally hinges on a single credential: a valid sponsor licence issued by UK Visas and Immigration (UKVI). Not every company holds one, and not every licence holder maintains it properly. Understanding the qualification process, obligations, and verification steps empowers you to assess whether a prospective employer can reliably sponsor your visa - and what questions to ask during negotiations.
This guide explains how UK companies qualify for sponsor licences, what maintaining that licence demands, and how you can check current UK employers offering visa sponsorship to identify organisations already licensed and actively hiring international talent.

What is a UK sponsor licence?
A UK sponsor licence is official permission from the Home Office allowing an organisation to sponsor foreign nationals under the points-based immigration system. The Worker sponsor licence specifically covers the Skilled Worker visa route, which replaced the Tier 2 (General) category in December 2020. Without this licence, a company cannot issue a Certificate of Sponsorship, and you cannot apply for a Skilled Worker visa based on that job offer.
Licences are not granted automatically. UKVI assesses each applicant organisation against a set of eligibility and suitability criteria designed to ensure sponsors understand their legal duties and can fulfil them consistently.
Eligibility and suitability: the two-part test
Eligibility criteria
To be eligible, an organisation must be operating lawfully in the UK, have appropriate HR systems to monitor sponsored employees, and demonstrate a genuine need to recruit from outside the resident labour market. UKVI expects applicants to show they are an established, trading entity - not a shell company or a startup with no track record. Sole traders and most partnerships face additional scrutiny, though limited companies and public bodies typically meet the threshold more easily.
The employer must also appoint at least three key personnel: an authorising officer (a senior individual legally accountable for the licence), a key contact (who liaises with UKVI), and a level-1 user (who manages day-to-day sponsorship tasks in the Home Office's Sponsorship Management System). Larger organisations often appoint additional level-1 users to share the workload.
Suitability criteria
Suitability goes beyond paperwork. UKVI will refuse or revoke a licence if the organisation or its key personnel have a history of immigration non-compliance, serious criminal convictions, fraud, or dishonesty. Previous sponsor licence revocations, even under a different company name or structure, raise red flags. The Home Office also considers whether the business has been subject to enforcement action by other regulators (tax authorities, employment tribunals, health and safety bodies) and whether it has paid relevant fines or penalties.
This two-part test means that even a well-established company can be refused if its compliance record is poor, while a newer firm with clean governance may succeed if it demonstrates robust systems.
The application process and what employers must provide
Applying for a sponsor licence requires the employer to complete an online application through the Home Office portal, pay the relevant fee (which varies by organisation size and whether the sponsor is a charity, educational institution, or commercial entity), and submit supporting documents. These typically include proof of trading (such as recent accounts, VAT returns, or contracts), evidence of appropriate premises, and details of the HR systems in place.
UKVI may conduct a pre-licence visit or audit, either in person or remotely, to verify that the organisation's operations match what was described in the application. Inspectors check that the business is genuine, that key personnel understand their duties, and that record-keeping systems can track sponsored workers' attendance, right to work, and any changes in circumstances.
Processing times vary. Straightforward applications from established organisations can be decided within eight weeks, but complex cases or those requiring additional evidence may take several months. Employers can pay for a priority service to expedite the decision, though this does not guarantee approval.
Ongoing duties: what licensed sponsors must do
Obtaining the licence is only the beginning. Sponsors must fulfil continuous reporting and record-keeping obligations, and failure to comply can result in licence suspension, downgrade, or revocation.
Reporting duties
Sponsors must report specific events to UKVI within ten working days. These include any change in a sponsored worker's circumstances (resignation, long-term absence, change of job title or salary, promotion, or any suspicion that the worker is breaching visa conditions). If the organisation itself undergoes structural changes - merger, acquisition, change of trading name, relocation - those must also be reported promptly.
Record-keeping and right-to-work checks
Employers must keep copies of each sponsored employee's passport, visa, and right-to-work documentation, along with records of contact details, job role, salary, and attendance or working patterns. For remote or hybrid workers, sponsors must demonstrate how they monitor compliance. These records must be kept for the duration of employment plus at least one year afterward, and must be made available to UKVI on request.
Compliance audits
UKVI conducts periodic audits of licensed sponsors, either announced or unannounced. Inspectors may visit the workplace, interview key personnel, and review records. A sponsor that cannot produce required documents, has failed to report changes, or is found to have sponsored workers in breach of their conditions risks having the licence downgraded (to a B-rating, which prevents issuing new Certificates of Sponsorship until issues are resolved) or revoked entirely.
How to verify if an employer has a sponsor licence
Before accepting a job offer that requires sponsorship, verify that the employer holds a valid Worker sponsor licence. The most reliable method is to consult the Register of Licensed Sponsors, published monthly by the Home Office. This spreadsheet lists every organisation currently licensed to sponsor Skilled Workers, along with their licence rating (A-rated sponsors are in good standing and can assign Certificates of Sponsorship; B-rated sponsors are under review and cannot issue new CoS until compliance is restored).
Search the register by the employer's exact legal name. If the company does not appear, they either do not hold a licence or it has been revoked. If they appear with a B-rating, ask what steps they are taking to restore A-rating status before you commit to the role. Some employers apply for a licence only after identifying a candidate they wish to hire; in that case, ask for evidence that the application has been submitted and request regular updates on its progress.
What sponsor licence costs mean for your negotiation
While you cannot pay the sponsor licence fee yourself (immigration rules prohibit passing certain sponsorship costs to the worker), understanding the employer's investment can inform your negotiation. The licence fee itself, the Immigration Skills Charge (a per-worker levy paid when assigning a Certificate of Sponsorship), and the administrative burden of compliance all represent real costs to the employer. For current fee amounts, refer to the official Home Office fee schedule.
Employers who already hold a licence and sponsor multiple workers spread these costs across a larger pool, making the marginal cost of sponsoring you lower. A company applying for its first licence to hire you faces a higher upfront investment and may be less familiar with the compliance obligations, which can introduce delays or risk if they underestimate the administrative load.
Red flags: when to question an employer's sponsorship capability
Certain warning signs suggest an employer may struggle to sponsor you reliably. If the company is newly incorporated with no trading history, has recently had a licence revoked, or cannot clearly explain their sponsorship process, proceed with caution. Similarly, if the employer asks you to pay any part of the sponsor licence fee, the Certificate of Sponsorship fee, or the Immigration Skills Charge, that request violates Home Office rules and suggests the employer does not understand (or is willing to flout) their legal obligations.
Employers who are vague about timelines, cannot provide a licence number for verification, or pressure you to start work before your visa is granted are also raising red flags. A responsible sponsor will guide you through each step, provide written confirmation of the job offer and sponsorship commitment, and wait for visa approval before your start date.
Frequently asked questions
Can a small business or startup sponsor a Skilled Worker visa?
Yes, small businesses and startups can apply for a sponsor licence if they meet the eligibility and suitability criteria. However, they must demonstrate genuine trading activity, robust HR systems, and the capacity to fulfil ongoing compliance duties. UKVI scrutinises newer or smaller organisations more closely to ensure they are not shell entities. If the business has a clean regulatory record and can show it needs skills not available in the resident workforce, size alone is not a barrier.
How long does a UK sponsor licence remain valid?
A sponsor licence does not have a fixed expiry date. Once granted, it remains valid indefinitely as long as the organisation continues to meet its duties and maintains an A-rating. However, UKVI can suspend, downgrade, or revoke the licence at any time if the sponsor fails to comply with reporting, record-keeping, or other obligations, or if the organisation's circumstances change in ways that affect suitability.
What happens if my employer's sponsor licence is revoked after I start working?
If your sponsor's licence is revoked, UKVI will curtail (shorten) your visa, typically giving you 60 days to find a new sponsor or leave the UK. You will receive a curtailment notice explaining the reason and the deadline. During that period, you can apply to switch to another employer who holds a valid licence and is willing to sponsor you, or you can apply for a different visa category if you qualify. Acting quickly is essential, as you cannot continue working for the original employer once their licence is revoked.
Can I check if an employer has a sponsor licence before applying for a job?
Yes. The Register of Licensed Sponsors is public and updated monthly. You can download the spreadsheet and search for any organisation by name before you apply or during the interview process. This allows you to confirm the employer's ability to sponsor and to ask informed questions about their experience with the Skilled Worker route. Many job seekers use this register alongside platforms that track visa-sponsoring employers to target their applications more strategically.
Do all UK employers need a sponsor licence to hire international workers?
No. Employers only need a sponsor licence if they wish to hire workers who require visa sponsorship under routes like the Skilled Worker visa. If a candidate already holds indefinite leave to remain, settled status under the EU Settlement Scheme, or another visa that grants unrestricted work rights (such as a UK Ancestry visa or a spouse visa with no work restrictions), the employer does not need a licence to employ that person. The licence requirement applies specifically to routes where the employer must issue a Certificate of Sponsorship.
