What Is SOC Code 3119?

Occupation Overview

SOC Code 3119 refers to science, engineering and production technicians not elsewhere classified. This category captures a broad range of technical roles that support scientists, engineers and technologists in laboratory, production and fieldwork environments but do not fall neatly into more specific SOC categories.

Typical Job Titles

• Laboratory technician
• Engineering technician
• Production technician
• Technical support officer
• Quality assurance technician
• Research technician
• Experimental technician

Core Duties

• Setting up, operating and maintaining laboratory or production equipment
• Conducting tests, experiments and quality checks
• Collecting, recording and interpreting technical data
• Assisting scientists, engineers and technologists with research or production tasks
• Following health and safety protocols in technical environments
• Calibrating instruments and ensuring equipment is fit for purpose

Skilled Worker Visa Eligibility for SOC Code 3119

Is SOC Code 3119 Eligible for Sponsorship?

Yes. Roles classified under SOC Code 3119 are eligible for the Skilled Worker visa. The occupation meets the required skill level of RQF Level 3 or above, which is the minimum threshold for sponsorship under this route.

Salary Requirements

Employers sponsoring workers under SOC Code 3119 must pay the higher of the general Skilled Worker salary threshold or the going rate set by the Home Office for this occupation code. Since April 2024, the general threshold increased significantly, so employers should check the latest Home Office guidance to confirm the current minimum before issuing a Certificate of Sponsorship.

• The general Skilled Worker minimum salary applies to all sponsored workers.
• The going rate for SOC Code 3119 must also be met if it exceeds the general threshold.
• New entrant rates may apply in certain circumstances, such as recent graduates or those switching from student visas.

English Language Requirement

Applicants for a Skilled Worker visa under this SOC code must demonstrate English language proficiency at B1 level or above on the Common European Framework of Reference. This can be evidenced through an approved English language test, a degree taught in English, or nationality from a majority English-speaking country.

How to Sponsor a Worker Under SOC Code 3119

Step 1: Obtain a Sponsor Licence

Before you can sponsor any overseas worker, your organisation must hold a valid UK sponsor licence issued by the Home Office. If you do not already have one, you will need to apply through the UK Visas and Immigration portal and demonstrate that your business is genuine, operating lawfully and capable of meeting sponsor duties.

Step 2: Identify the Correct SOC Code

Assigning the correct SOC code to the role is critical. Using the wrong code can result in the visa being refused or your licence being reviewed. SOC Code 3119 should only be used where the technician role genuinely does not fit a more specific occupation code within the science and engineering category.

Step 3: Assign a Certificate of Sponsorship

Once you have confirmed the role qualifies, you must assign a Certificate of Sponsorship (CoS) to the worker through the Sponsor Management System. The CoS must accurately reflect the job title, duties, salary and start date. Any discrepancy between the CoS and the actual role can trigger a compliance investigation.

Step 4: Worker Submits Visa Application

After receiving the CoS reference number, the overseas worker applies for a Skilled Worker visa online. They must provide biometric information, pay the application fee and the Immigration Health Surcharge, and submit supporting documents including their passport, proof of English language ability and financial evidence.

Step 5: Ongoing Compliance

Sponsoring a worker is not a one-off task. As a licence holder, your organisation must carry out right to work checks, maintain accurate records, report changes in the worker's circumstances to the Home Office, and cooperate with any audits or inspections.

Sponsor Licence Duties for This Occupation

Record Keeping

Sponsors must keep up-to-date records for every sponsored worker, including copies of identity documents, contact details, and evidence of right to work checks. These records must be available for inspection at any time.

Reporting Obligations

You are required to report certain events to the Home Office within set timeframes. These include a worker failing to start their role, unexplained absences, significant changes to the job or salary, and termination of employment.

Genuine Vacancy Requirement

The Home Office expects that every sponsored role is genuine. For SOC Code 3119, you should be able to demonstrate that the technician work is real, ongoing and genuinely requires the skills of the sponsored individual. Fabricated or inflated roles can result in licence suspension or revocation.

Shortage Occupation and Immigration Salary List

Is SOC Code 3119 on the Immigration Salary List?

Employers should check the current Immigration Salary List published by the Home Office to determine whether SOC Code 3119 qualifies for a reduced salary threshold. The list is updated periodically and certain technical occupations may attract a discount against the standard going rate. Always verify the latest version before assigning a CoS.

Recruiting Science and Engineering Technicians from Overseas

Where to Find Candidates

• International job boards and specialist STEM recruitment agencies
• University graduate networks in countries with strong science and engineering programmes
• LinkedIn and professional scientific associations
• Government-to-government recruitment schemes where applicable

Resident Labour Market Test

The formal Resident Labour Market Test was removed from the Skilled Worker route. However, employers are still expected to act in good faith and consider whether suitable settled workers are available before recruiting internationally. Keeping records of your recruitment process remains good practice and supports your position in any compliance review.

Switching Visa Categories

Workers already in the UK on other visa categories, such as a Graduate visa or Student visa, may be able to switch into the Skilled Worker route from within the UK if they receive a valid job offer and CoS from a licensed sponsor. This can be a practical route for employers who have already identified talent during placement programmes or internships.

Common Mistakes Employers Make

Misclassifying the SOC Code

Using SOC Code 3119 as a catch-all when a more specific code applies is a frequent error. The Home Office may challenge the classification during a compliance visit, and errors here can affect the validity of the CoS and the worker's leave.

Underpaying Against the Going Rate

Even a small shortfall against the required salary can result in a visa refusal or a compliance finding against your licence. Always calculate the going rate carefully using the latest Home Office appendix before submitting the CoS.

Failing to Update the Home Office

Many employers miss reporting deadlines when a sponsored worker changes role, moves to a different site, or leaves the organisation. Late or missed reports are among the most common reasons for sponsor licence downgrading or revocation.
