What Is SOC Code 5236?

SOC Code 5236 covers rail and rolling stock builders and repairers. This occupation group includes workers who assemble, maintain, inspect and repair train engines, carriages, wagons and other rolling stock used on the rail network. These are skilled trade roles that require specialist technical knowledge of railway engineering systems.

Typical Job Titles Under SOC 5236

• Rolling stock technician
• Train maintenance engineer
• Rail vehicle fitter
• Traction maintenance technician
• Rolling stock inspector
• Carriage and wagon examiner
• Diesel or electric multiple unit technician

Core Duties in This Occupation

• Assembling and fitting components to train engines and rolling stock
• Carrying out scheduled preventative maintenance on rail vehicles
• Diagnosing faults and carrying out repairs to mechanical, electrical and pneumatic systems
• Inspecting rolling stock to ensure safety and regulatory compliance
• Maintaining accurate records of maintenance work and inspections
• Working to rail industry safety standards including those set by the Office of Rail and Road

Is SOC Code 5236 Eligible for Skilled Worker Sponsorship?

Yes. Rail and rolling stock builders and repairers (SOC 5236) appear on the list of eligible occupations for the Skilled Worker visa. This means UK employers with a sponsor licence can assign a Certificate of Sponsorship to overseas candidates applying for this role.

Skill Level and RQF Threshold

The Skilled Worker route requires roles to be at RQF Level 3 or above. SOC 5236 meets this threshold, reflecting the technical training and practical expertise required to work safely on railway rolling stock.

Salary Requirements

Sponsored workers must be paid at least the higher of the general salary threshold or the going rate for their specific occupation code. Employers should check the current going rate for SOC 5236 on the Home Office's published occupation list before assigning a Certificate of Sponsorship. Underpaying a sponsored worker is a serious compliance breach that can lead to licence suspension or revocation.

How to Sponsor a Rail and Rolling Stock Builder or Repairer

Step 1: Obtain a Sponsor Licence

Before you can hire an overseas worker, your organisation must be approved as a licensed sponsor by the Home Office. The application is made through the Sponsor Management System and requires evidence that your business is genuine, operates lawfully and has suitable HR systems in place to meet compliance obligations.

Step 2: Identify the Role and Confirm Eligibility

Confirm that the vacancy maps correctly to SOC Code 5236 and that the offered salary meets or exceeds the going rate threshold. Keep a written record of how you determined the SOC code allocation for the role.

Step 3: Conduct a Resident Labour Market Test (Where Required)

While the formal Resident Labour Market Test was abolished for most Skilled Worker roles, employers should still document their recruitment process and demonstrate that the overseas hire was made on merit. This supports your compliance position during any Home Office audit.

Step 4: Assign a Certificate of Sponsorship

Once you have identified the candidate, assign a Certificate of Sponsorship through the Sponsor Management System. The certificate must accurately reflect the job title, SOC code, salary, work location and employment start date.

Step 5: Worker Applies for Their Visa

Using the Certificate of Sponsorship reference number, the worker applies for a Skilled Worker visa online. Processing times vary, but most straightforward applications are decided within three weeks if applied from outside the UK.

Step 6: Carry Out a Right to Work Check

Before the worker begins employment, you must conduct a compliant right to work check. For visa holders this typically involves using the Home Office online checking service with the worker's share code. Keep a record of the check and the date it was carried out.

Ongoing Sponsor Compliance Duties

Holding a sponsor licence is not a one-off process. Employers sponsoring workers under SOC 5236 must maintain active compliance throughout the duration of each sponsored worker's employment.

Reporting Duties

• Report any change in the worker's employment circumstances, including changes to salary, working hours, job title or work location
• Report if the worker does not turn up to start work or if their employment ends earlier than expected
• Report any significant changes to your organisation, such as a change of ownership or merger

Record-Keeping Duties

• Retain copies of right to work documentation for each sponsored worker
• Keep up-to-date contact details and current home address for all sponsored employees
• Maintain records of Certificates of Sponsorship assigned and the basis for salary decisions
• Store evidence of qualifications or professional registrations where relevant to the role

Monitoring Duties

• Track visa expiry dates and remind workers to renew in good time
• Monitor attendance and follow up absences promptly
• Ensure the worker is only performing duties consistent with the sponsored role

Rail Industry Considerations for Employers

Beyond immigration compliance, employers in the rail sector must ensure that overseas workers meet any industry-specific certification or competency requirements before carrying out safety-critical work.

Industry Safety Standards

The Office of Rail and Road sets out safety requirements for workers carrying out maintenance and inspection of rolling stock. Overseas workers may need to demonstrate equivalence of their qualifications or complete additional UK-specific training before being permitted to work unsupervised on safety-critical systems.

Professional Registrations and Competency Frameworks

Some rail employers require workers to hold competencies within industry frameworks such as the National Skills Academy for Rail or demonstrate alignment with Rail Industry Competency Standards. Employers should factor in the time and cost of any bridging training when planning overseas recruitment.

Common Mistakes Employers Make When Sponsoring Skilled Trades Workers

• Assigning the wrong SOC code, which can lead to the visa application being refused or compliance issues during an audit
• Setting a salary below the going rate for SOC 5236, which invalidates the Certificate of Sponsorship
• Failing to update the Sponsor Management System when a worker changes their job title or location within the business
• Not carrying out right to work checks before the worker's first day
• Allowing a sponsored worker's visa to expire without taking action, which can expose the employer to a civil penalty
• Neglecting to renew the sponsor licence itself before expiry

Frequently Asked Questions

What does SOC Code 5236 cover?

Can I sponsor an overseas worker as a rail and rolling stock repairer?

Yes, provided your organisation holds a valid Skilled Worker sponsor licence. SOC 5236 is on the eligible occupations list, which means you can assign a Certificate of Sponsorship and the worker can apply for a Skilled Worker visa.

What salary must I pay a sponsored rail and rolling stock technician?

You must pay at least the higher of the general Skilled Worker salary threshold or the specific going rate for SOC 5236. The going rate is published by the Home Office and is updated periodically. Always check the current figure before assigning a Certificate of Sponsorship.

Do I need a sponsor licence before I can hire someone under SOC 5236?

Yes. You cannot assign a Certificate of Sponsorship without an active sponsor licence. The licence application is submitted to the Home Office and must be approved before any overseas worker can be sponsored.

What happens if I pay a sponsored worker below the going rate?

Paying below the going rate is a serious breach of sponsor duties. The Home Office can downgrade your licence rating, suspend your licence or revoke it entirely. Workers already in the UK could also have their leave curtailed.

Are there any additional qualifications needed for rail workers beyond immigration requirements?

Yes. Workers carrying out safety-critical tasks on rolling stock must meet the competency requirements set by the Office of Rail and Road and your organisation's own safety management system. Overseas workers may need to complete UK-specific training or have their existing qualifications recognised before starting certain duties.
