Sponsoring Overseas Workers Under SOC 5221

Is SOC 5221 Eligible for the Skilled Worker Visa?

Yes. Metal Machining Setters and Setter-Operators (SOC 5221) appear on the list of eligible occupations for the UK Skilled Worker visa. This means UK employers with a valid sponsor licence can assign a Certificate of Sponsorship to overseas candidates applying for this role.

Minimum Salary Requirements

From April 2024, the general minimum salary threshold for Skilled Worker visa applications increased significantly. Employers sponsoring workers under SOC 5221 must pay the higher of the general threshold or the going rate for the specific occupation code. It is essential to check the latest going rate published by the Home Office before issuing a Certificate of Sponsorship, as underpaying can result in licence suspension or curtailment of the worker's visa.

English Language Requirements

Applicants for the Skilled Worker visa must demonstrate English language proficiency at B1 level or above on the Common European Framework of Reference. This can be satisfied through an approved English language test, a degree taught in English, or nationality from a majority English-speaking country as defined by the Home Office.

Obtaining and Maintaining a Sponsor Licence

Applying for a Sponsor Licence

To hire overseas workers under SOC 5221, your business must first obtain a Skilled Worker sponsor licence from UK Visas and Immigration. The application requires you to demonstrate that your organisation is a genuine trading entity, that you have suitable HR systems in place, and that key personnel have been nominated to manage sponsorship duties.

Key Personnel Roles

• Authorising Officer - a senior, responsible person accountable for the licence.
• Key Contact - the main point of contact with the Home Office.
• Level 1 User - responsible for day-to-day management of the Sponsor Management System.

Ongoing Compliance Obligations

Once licensed, sponsors must fulfil a range of ongoing duties to retain their licence. Failure to comply can result in downgrading to a B-rating, suspension, or outright revocation of the licence, which would affect all sponsored workers.

• Conducting right to work checks before employment begins.
• Maintaining accurate and up-to-date records for all sponsored workers.
• Reporting changes in circumstances, such as absences, role changes, or if a worker stops working for you.
• Cooperating with Home Office compliance visits and audits.
• Ensuring sponsored workers are only doing the job stated on their Certificate of Sponsorship.

Right to Work Checks for Metal Machining Roles

Who Needs a Right to Work Check?

All employers in the UK are legally required to carry out right to work checks on every employee before they start work, regardless of their nationality or immigration status. This applies equally to British citizens, settled EU nationals, and those on sponsored visas.

Acceptable Documents and Online Checks

Right to work can be verified using physical documents listed in List A or List B of the Home Office guidance, or via the online right to work checking service for those with a share code. For sponsored workers under a Skilled Worker visa, employers should retain a copy of the visa vignette or eVisa confirmation and record the date the check was performed.

Repeat Checks for Time-Limited Permissions

Where a worker's right to work is time-limited, such as those on a Skilled Worker visa, employers must conduct a follow-up check before the expiry of the worker's leave. Failing to do so removes the statutory excuse and exposes the employer to a civil penalty of up to £60,000 per illegal worker.

Recruiting Metal Machining Setters: Practical Considerations

Resident Labour Market and Genuine Vacancy

While the Skilled Worker route does not currently require a formal Resident Labour Market Test, employers must ensure the role is a genuine vacancy and that the job description accurately reflects the duties under SOC 5221. The Home Office can scrutinise whether a role has been created artificially to facilitate a visa application.

Assessing Candidate Qualifications and Experience

For metal machining roles, relevant qualifications might include apprenticeships, NVQs in machining, or equivalent international credentials. Practical assessment of CNC programming skills, knowledge of tolerancing standards such as ISO and BS, and familiarity with inspection equipment are typically relevant to this occupation.

Induction and Workplace Safety

Metal machining environments carry specific health and safety risks, including exposure to cutting fluids, metal swarf, noise, and vibration. Employers must provide adequate induction training, appropriate personal protective equipment, and ensure compliance with the Health and Safety at Work Act 1974 and relevant machinery directives.

Certificate of Sponsorship for SOC 5221

Assigning a Certificate of Sponsorship

Once your sponsor licence is active, you assign a Certificate of Sponsorship through the Sponsor Management System. The CoS must accurately reflect the job title, SOC code, salary, and start date. Errors on the CoS can lead to visa refusals or compliance issues, so accuracy is critical.

Defined and Undefined CoS

• A defined CoS is used for workers applying for entry clearance from outside the UK and must be requested from the Home Office before assignment.
• An undefined CoS is used for workers already in the UK switching or extending their visa and can be assigned from your annual allocation.

CoS Validity and Worker Application Timeline

A Certificate of Sponsorship is valid for three months from the date of assignment, within which the worker must submit their visa application. Sponsors should coordinate closely with candidates to ensure applications are submitted promptly to avoid the CoS expiring.
