Any UK business looking to recruit an overseas national under the skilled worker route must first hold a valid sponsor licence permitting sponsorship under this category.
In this guide for businesses, we explain the rules and requirements to apply for a Skilled Worker sponsor licence and obtain permission to hire non-UK resident workers. We also cover process, costs, licence duration, sponsor duties, and best-practice compliance to help reduce risk before and after grant.
What this article is about: a practical, legally accurate overview of the Skilled Worker sponsor licence regime for UK employers, including eligibility, evidence, decision-making, fees, CoS allocation, SMS roles, thresholds (updated to 22 July 2025 figures), and ongoing compliance.
What is a Skilled Worker sponsor licence?
A Skilled Worker sponsor licence is permission granted by the Home Office authorising the licence-holder to assign Certificates of Sponsorship (CoS) to workers under the Skilled Worker route, as set out in Appendix Skilled Worker of the Immigration Rules. A Skilled Worker must have an offer of a genuine job from an approved sponsor that meets the route criteria before they can validly apply to enter or stay in the UK. The sponsor confirms this by assigning a CoS to the worker via the Sponsor Management System (SMS).
The Skilled Worker route is the main work route for overseas nationals and allows UK-based employers to recruit to a wide range of skilled vacancies, provided the role meets the applicable skill and salary thresholds and all other sponsorship conditions are satisfied.
What are the Skilled Worker sponsor licence requirements?
There are general and route-specific requirements for approval. To be eligible, the Home Office must be satisfied that the organisation is:
- a genuine organisation operating lawfully in the UK
- honest, dependable and reliable, and not engaging, nor having engaged, in behaviour or actions not conducive to the public good
- capable of carrying out its sponsor duties and evidencing compliance within prescribed timeframes, with reference to its existing recruitment practices and HR systems
The Home Office will assess the applicant’s history and background, including any previous non-compliance with the Immigration Rules, and the background of those involved in day-to-day operations and the nominated key personnel (including any criminal convictions or adverse immigration history). Key personnel are the individuals responsible for managing sponsorship and the SMS.
In addition to the general requirements, the applicant must be able to offer a job role that:
- is genuine and not a sham, and has not been created mainly so the worker can apply for entry clearance or permission to stay
- does not amount to hiring the worker to a third party who is not the sponsor to fill a position with that party (temporary or permanent), or contracting the worker to undertake an ongoing routine role or provide an ongoing routine service for a third party
- meets both the skill level and salary requirements for the Skilled Worker route
A Skilled Worker must have a job offer in an eligible skilled occupation from a Home Office-approved sponsor, as set out in Table 1 or Table 2 of Appendix Skilled Occupations, or under occupation code 6145 (care workers and home carers). In most cases, the role must be skilled to RQF Level 3 (A-level standard) or above. The worker does not need A-levels; the role must be at that level.
All sponsored jobs must also meet the salary requirements in Appendix Skilled Worker and the relevant tables in Appendix Skilled Occupations. From 22 July 2025, the salary must usually meet or exceed all of the following:
- the general salary threshold of £41,700 per year (equivalent to £23.08 per hour), unless a lower threshold applies (for example £33,400 for certain discounted cases such as eligible shortage, PhD or new entrant scenarios; £25,000 for specified Health & Care roles; or £31,300 in applicable transitional cases)
- the ‘going rate’ for the occupation code
- any applicable minimum hourly rate
Where a discounted threshold or transitional provision is relied upon, the sponsor must ensure the role and circumstances fall squarely within the applicable criteria and retain evidence accordingly.
What is the process to apply for a Skilled Worker sponsor licence?
To apply for a sponsor licence, the applicant must first register the organisation’s details with UK Visas and Immigration (UKVI) and submit the online application form. The form requires the nomination of key personnel, some or all of whom will access the Sponsorship Management System (SMS) once the licence is granted. The application also asks for an estimate of the number of Certificates of Sponsorship (CoS) likely to be required in the first year.
Nominating key personnel
An authorising officer must be appointed to manage the application. This must be the most senior person responsible for the recruitment of migrant workers. The applicant must also nominate a key contact, who will act as the main liaison with UKVI, and at least one Level 1 user, who will manage the day-to-day operation of the licence via the SMS.
Once a sponsor licence is granted, additional Level 1 users may be appointed, as well as Level 2 users, who have more limited SMS permissions. If the authorising officer or key contact require SMS access, they must also be set up as Level 1 or Level 2 users.
Key personnel roles can be filled by the same person or shared between different people, but they must usually be either paid members of staff or office holders. They must also be based in the UK during their tenure and meet suitability requirements (e.g. no relevant criminal convictions, no previous sponsor compliance failures).
Deciding on CoS allocation
At application stage, the organisation must decide how many workers it intends to sponsor in its first year and request an allocation of CoS accordingly. The sponsor must be able to justify this request to UKVI, and may be asked to provide information about current vacancies and recruitment plans.
A sponsor must assign a valid CoS to each worker it wishes to sponsor before that worker can apply to enter or remain in the UK. Careful planning is therefore essential, as the sponsor may need to demonstrate a genuine need for each requested CoS.
Submitting supporting documents
On completion of the online application, the applicant must pay the relevant fee and submit a signed and dated submission sheet (signed by the authorising officer) and all required supporting documents within five working days. The required evidence is set out in Sponsor Guidance Appendix A and depends on the type and size of the organisation. Documents must be original or certified copies and must demonstrate that the organisation is genuine and operating lawfully in the UK.
UKVI will consider the application once payment and documents are received. A decision is usually made within eight weeks, but may take longer if UKVI decides to conduct a compliance visit to assess the applicant’s HR systems and ability to meet sponsor duties. Where a site visit is required, the licence will not be granted until UKVI is satisfied the organisation is capable of compliance.
If granted, a Skilled Worker sponsor licence is valid for four years, unless revoked or surrendered. To continue sponsoring beyond that period, the licence must be renewed before expiry.
What happens once a Skilled Worker sponsor licence has been granted?
Once a Skilled Worker sponsor licence has been granted, the sponsor is added to the Register of Licensed Sponsors. The nominated Level 1 user is given full access to the Sponsorship Management System (SMS) to manage the licence on a daily basis.
To sponsor an overseas national on the Skilled Worker route, the sponsor must assign a valid Certificate of Sponsorship (CoS) to that individual using the SMS. The worker can then apply for a Skilled Worker visa. Before assigning a CoS, the sponsor must confirm that the role and the worker meet the requirements of the route. Each CoS attracts a fee, and the sponsor will also be liable for the Immigration Skills Charge unless an exemption applies.
Following assignment of a CoS, the sponsor must comply with ongoing reporting and record-keeping duties. This includes notifying the Home Office if:
- a sponsored worker does not start employment as expected
- a worker is absent without permission
- there are significant changes to the worker’s job, salary, or employment status
- there are material changes to the organisation itself, such as mergers, takeovers or relocations
Sponsors must also retain specified documents for each sponsored worker and maintain robust HR processes. Failure to meet these duties can result in enforcement action, including suspension, downgrading, or revocation of the licence.
UKVI has powers to conduct announced or unannounced compliance visits both before and after a licence is granted. During such visits, caseworkers will review HR systems, interview staff, and request records to ensure compliance. Breaches can have serious consequences, including civil penalties and reputational damage.
What is the cost of applying for a Skilled Worker sponsor licence?
The costs of obtaining and maintaining a Skilled Worker sponsor licence include the application fee, the Immigration Skills Charge (ISC) for each sponsored worker, and the fee for assigning each Certificate of Sponsorship (CoS).
The sponsor licence application fee depends on the size and type of organisation:
- Small or charitable sponsors: £536
- Medium or large sponsors: £1,476
The ISC must be paid when assigning a CoS to most Skilled Worker applicants. The charge varies according to sponsor size and the length of sponsorship (as shown on the CoS):
- Small or charitable sponsors: £364 for the first 12 months, plus £182 for each additional 6 months
- Medium or large sponsors: £1,000 for the first 12 months, plus £500 for each additional 6 months
Some exemptions apply. For example, the ISC does not apply if the worker is switching from a Student visa within the UK, or if the worker is sponsored under certain PhD-level occupation codes.
The fee for assigning a CoS to a Skilled Worker applicant is £239. This is payable in addition to the ISC.
It is important for sponsors to budget carefully, as the cumulative costs of licence application, ISC liabilities, and CoS fees can be substantial, particularly for organisations sponsoring multiple workers.
What best practice tips can be followed for Skilled Worker visa sponsorship?
The process of securing and maintaining a Skilled Worker sponsor licence can be complex, costly, and carries significant compliance risk. Following best practice can help to maximise the prospects of success and reduce the likelihood of enforcement action.
Key points for sponsors include:
- Ensure robust HR and recruitment systems are in place prior to applying, as UKVI frequently conducts compliance visits before and after granting a licence
- Prepare all mandatory documentation in advance, ensuring the evidence satisfies Appendix A requirements, and submit it within five working days of the online application
- Make sure the nominated authorising officer and key contact are available to respond quickly to UKVI queries during the application process
- Retain thorough records for each sponsored worker and keep systems updated to allow for accurate and timely reporting to UKVI
- Conduct regular internal audits to identify gaps or risks in compliance and take prompt corrective action
Applications for Skilled Worker sponsor licences are closely scrutinised and compliance is monitored on an ongoing basis. By embedding proper procedures and controls, sponsors can reduce the risk of refusal, suspension, or revocation, and demonstrate that they are reliable and trustworthy licence holders.
Where the process is unclear, or where the organisation has a complex structure or history of immigration non-compliance, it can be highly beneficial to seek legal advice from an immigration specialist before and during the application process.
FAQs
1. How long does it take to get a Skilled Worker sponsor licence?
Most applications are decided within eight weeks. However, if UKVI conducts a compliance visit or requires further information, the process can take longer.
2. How long does a Skilled Worker sponsor licence last?
A Skilled Worker sponsor licence is valid for four years. It must be renewed before expiry to continue sponsoring workers. Licences can also be revoked earlier if compliance duties are breached.
3. Can key personnel be the same person?
Yes. The roles of authorising officer, key contact and Level 1 user may be held by the same individual, provided they meet the suitability requirements and are based in the UK.
4. What happens if a sponsor breaches its duties?
Breaches of sponsor duties can result in enforcement action. UKVI may suspend, downgrade or revoke the licence, impose civil penalties, or prevent the sponsor from sponsoring new workers until issues are resolved.
5. What are the main costs of sponsorship?
The main costs are the sponsor licence application fee, the Immigration Skills Charge for each sponsored worker (unless exempt), and the £239 fee for each Certificate of Sponsorship issued.
Conclusion
Applying for and maintaining a Skilled Worker sponsor licence is a significant commitment for UK employers. It requires demonstrating to UKVI that the organisation is genuine, compliant, and capable of meeting all sponsorship duties. Once granted, sponsors must continue to uphold strict reporting, record-keeping, and compliance standards, subject to ongoing monitoring and potential site visits.
With the salary thresholds having increased substantially from July 2025 and with the Home Office maintaining a rigorous approach to compliance, careful preparation and ongoing diligence are vital. Employers should ensure their HR systems are robust, that key personnel are trained and accountable, and that internal audits are conducted regularly.
By approaching sponsorship strategically and seeking professional advice where appropriate, organisations can minimise risks and maximise the benefits of accessing the global talent pool under the Skilled Worker route.
