Current sponsor guidance · Checked 7 September 2026
One proposed worker is not the problem. An unconvincing business or role is.
The Home Office assesses the organisation, its proposed sponsorship activity and its capacity to comply. A proportionate application for 1 genuine worker can succeed, but the evidence must explain why that role exists and how a small team will operate the licence.
The position
Can a small business obtain a sponsor licence for only 1 employee?
Yes. Current Home Office sponsor guidance does not set a minimum headcount, turnover or number of sponsored workers for an ordinary Worker sponsor licence. A genuine UK organisation may apply because it intends to sponsor 1 worker. It must still provide the required Appendix A documents, appoint eligible key personnel, show that the single job is genuine and eligible, justify the Certificate of Sponsorship it expects to use, demonstrate that the salary and role fit the business, and operate the complete sponsor-compliance system. The Home Office can refuse the application or grant a zero Certificate of Sponsorship allocation if the recruitment case is not adequately established.
- The absence of a published minimum does not create an entitlement to a licence.
- A role created mainly to secure immigration permission is not a genuine vacancy.
- The proposed worker must not exercise unchecked control over the sponsor licence or their own sponsorship.
A sponsor licence is not reserved for large employers or businesses planning repeated overseas recruitment. A small company can apply because it needs 1 eligible worker. The scale of the application should be proportionate to the business, but the underlying legal and compliance requirements are not reduced.
In a micro business, the proposed role often receives closer factual scrutiny because there is less organisational context. The Home Office may ask whether the duties fit the company's activities, whether the salary is sustainable, who currently performs the work and why a full-time sponsored position is commercially credible.
The right response is not to inflate the recruitment plan. It is to evidence the company that exists, define the single role precisely and show how the organisation will perform sponsor duties even if the proposed worker is senior, connected to the owners or central to the business.
01 · No numerical threshold
The sponsor rules do not impose a minimum headcount or recruitment volume.
The current sponsor guidance asks how many workers the organisation is likely to sponsor during the first year and uses that answer to determine the initial Certificate of Sponsorship allocation. It does not state that an employer must already have a particular number of staff or intend to sponsor more than 1 person.
That does not make size irrelevant. The Home Office considers whether the business is genuinely operating or trading, whether it can offer eligible employment, whether its key personnel are suitable and whether its systems can meet the sponsor duties. A smaller organisation may have fewer documents and simpler processes, but each conclusion still requires reliable evidence.
02 · Genuine employment
The single role must fit the actual business rather than the immigration objective.
The job description should explain real duties, occupation code, skill level, weekly hours, salary, work location, reporting line and the commercial outcome expected from the appointment. Generic management language is especially vulnerable where the company has limited trading activity or no team for the proposed manager to manage.
Current guidance gives the example of a small fast-food outlet seeking to sponsor a full-time business development, human resources and publicity manager. The concern is not that a small outlet can never sponsor. It is that the scale and nature of the proposed role may not be credible for that business.
Contracts, forecasts, existing workload, customer demand, organisational charts and evidence of failed or continuing recruitment can help explain the need. They should support the role described on the application, not be assembled around a different position after questions are raised.
03 · Financial reality
Affordability should be considered in context, even where there is no formal turnover minimum.
The sponsor rules do not impose a universal minimum turnover for an ordinary licence. The Home Office can nevertheless examine whether the proposed salary is credible in light of accounts, bank activity, investment, contracts, payroll and the organisation's wider commitments.
A newly funded company may be able to support a skilled role before substantial revenue is generated. A mature but lightly capitalised company may struggle to explain a salary that exceeds its ordinary operating capacity. The evidence should distinguish secured funding and contracted income from aspiration.
04 · Certificate allocation
Request the Certificate of Sponsorship that the business can actually justify.
The licence application asks for an estimate of the Certificates of Sponsorship required in the first year. A company intending to hire 1 person should ordinarily explain that specific requirement, including whether the worker will apply from within or outside the UK and the likely timing.
The Home Office may reduce an unsupported request or set the allocation at zero. A deliberately inflated request can weaken credibility, while requesting zero through misunderstanding can delay the recruitment after the licence is granted. Defined Certificates for relevant entry-clearance applications are requested separately under the Skilled Worker process.
One identified vacancy
Explain why the role exists, when it starts and how it fits the business plan.
One proportionate request
Match the initial CoS need to the worker's likely application location and timetable.
One complete evidence record
Align the role, salary, organisation, recruitment and operational documents.
Full ongoing duties
Operate monitoring, reporting, record keeping and right-to-work control despite the small scale.
05 · Governance
A small team still needs eligible key personnel and genuine control.
The organisation must appoint an Authorising Officer, Key Contact and Level 1 User who satisfy the current requirements. One person may hold more than 1 role where permitted, but the appointment should reflect real senior responsibility and day-to-day access rather than a name added for the application.
Where the proposed sponsored worker is an owner, director or the only intended employee, the governance structure requires particular care. The organisation must remain capable of supervising the role, controlling the Sponsor Management System and responding independently if the worker's duties, salary, attendance or employment change.
06 · Compliance capacity
Compliance can be simple, but it cannot be informal.
A small employer may use a concise digital system rather than an enterprise human-resources platform. It must still retain the records required by Appendix D, monitor attendance and contact details, complete right-to-work checks, track visa expiry and report specified changes within the applicable deadlines.
The responsible people should be able to explain the system without relying entirely on an external adviser. Legal and human-resources support can design and review the controls, but the sponsor remains responsible for operating them.
07 · Commercial decision
The licence should be assessed against the complete recruitment timetable and cost.
For a single hire, the business should model the licence application, priority availability, CoS process, immigration application, right-to-work start date and ongoing sponsor charges. The licence does not guarantee that the worker will qualify, and the worker must not begin sponsored employment until valid permission and the required check are in place.
A licence may still be commercially justified where the role is critical, the candidate is scarce or the company expects future international recruitment. If the job can be filled by a person who does not need sponsorship, or the role is not yet settled, the business may decide that the application is premature.
08 · Counsel judgment
Proportionality strengthens a small-company application when every fact remains consistent.
A credible file does not pretend that a micro business has the structure of a multinational. It identifies who makes decisions, how records are kept, where the worker will work and how the business will fund and supervise the role. The same explanation should appear across the online application, submission, documents and any Home Office interview or visit.
The central risk is inconsistency: a role described as strategic but evidenced as routine, a salary unsupported by finance, an organisation chart that gives the worker unchecked control, or a CoS request unrelated to the actual hiring plan. Those defects, not the number 1, determine the strength of the case.

Practical questions.
Is there a minimum number of employees for a sponsor licence?
No minimum headcount is stated in the current general sponsor guidance. The Home Office instead assesses whether the organisation is genuine, suitable, capable of compliance and able to offer genuine eligible work.
Can a company apply for only 1 Certificate of Sponsorship?
Yes. The initial request should reflect the genuine first-year need and explain the proposed role and timing. The Home Office may grant the requested allocation, reduce it or set it at zero according to the evidence.
Does a small company need a minimum turnover?
There is no universal minimum turnover for an ordinary Worker sponsor licence. Financial records can still be examined to decide whether the business is genuine and whether the proposed salary and role are credible and sustainable.
Can the only proposed employee be the company owner?
Potentially, but ownership does not create a separate visa route or relax the requirements. The company, role, salary, worker eligibility and sponsor governance must all be genuine, and the licence should not leave the worker exercising unchecked control over their own sponsorship.
Will a sponsor licence guarantee the worker's visa?
No. The licence decision, Certificate of Sponsorship and worker's immigration application are separate. The worker must meet the complete route requirements and may start only after valid permission and the required right-to-work check.
Can an external adviser run compliance for the company?
An adviser can design systems, provide training and support the application. The licensed organisation and its key personnel remain accountable and must understand and operate the sponsor duties themselves.
