Understanding SOC Codes and How They Affect Your UK Work Visa

If you’re applying for a Skilled Worker visa — or your employer is applying to sponsor you — you’ll encounter something called a SOC code. This seemingly technical detail is actually one of the most important factors determining whether your role qualifies for sponsorship and what salary thresholds apply. Getting it wrong can cause costly delays or refusals.

What is a SOC Code?

SOC stands for Standard Occupational Classification. It’s a numerical code that the UK government uses to classify jobs and occupations for statistical and administrative purposes.

For immigration purposes, SOC codes serve a critical function: they determine:

Whether a job is eligible for the Skilled Worker visa (since 22 July 2025 most roles must be at RQF level 6 / degree level or above)
What minimum salary (‘going rate’) applies to the specific occupation
Whether the occupation is on the Immigration Salary List, which affects salary requirements
Which visa route is appropriate (e.g., Skilled Worker vs Temporary Worker)

The UK currently uses SOC 2020 codes, which consist of four digits (e.g., 2134 for programmers and software development professionals).

The Structure of SOC Codes

SOC codes are organised hierarchically:

Level	Example	Description
Major group (1 digit)	2	Professional occupations
Sub-major group (2 digits)	21	Science and research professionals
Minor group (3 digits)	213	IT professionals
Unit group (4 digits)	2136	Programmers and software development professionals

For visa purposes, the full four-digit code is used.

Why SOC Codes Matter So Much

Eligibility Determination

Not all jobs qualify for the Skilled Worker visa. Since 22 July 2025 the role must generally be at RQF level 6 or above (degree-level standard) — up from the previous RQF level 3 (A-Level) threshold. A limited set of lower-skilled roles remains eligible via the Temporary Shortage List. The SOC code helps the Home Office assess this.

When your employer assigns a Certificate of Sponsorship, they must enter the appropriate SOC code. The Home Office then checks whether:

That code is eligible for the visa route being used
The salary being offered meets or exceeds the going rate for that code
The code accurately reflects the actual job being performed

The “Going Rate” Salary Requirement

Each eligible SOC code has a specific going rate — the minimum salary that must be paid for a role with that code. The going rate is set by the Home Office based on UK earnings data from the Annual Survey of Hours and Earnings (ASHE).

Under the standard salary option, you must be paid whichever is higher:

The general threshold (£41,700 in 2026)
The going rate for your specific SOC code

Example:

SOC 2142 (Graphic and multimedia designers): Going rate of £33,400 → under the standard option, you’d need £41,700 (the cash threshold wins)
SOC 2134 (Programmers and software development professionals): Going rate of £54,700 → under the standard option, you’d need £54,700 (the going rate wins)

Other tradeable-points options change one or both of those figures. For example, the new entrant option uses 70% of the going rate with a £33,400 cash floor for eligible applicants.

Immigration Salary List Roles

Some SOC codes appear on the Immigration Salary List (ISL). Under the current Option D rules, an ISL role has a reduced cash threshold of £33,400, but it must still be paid the full going rate for its occupation code. The 20% reduction applies to the general threshold only; it is not a 20% discount on the going rate. ISL applications also attract lower visa fees.

How to Find the Right SOC Code for Your Job

Method 1: Use the Government’s Eligible Occupations Table

The Home Office publishes a table of all eligible SOC codes for the Skilled Worker route on gov.uk. This table shows:

The SOC code
Occupation title
Going rate (annual salary)
Whether it’s on the shortage list
Any special conditions

Search for your job title to find the most relevant code.

Method 2: Use the ONS Occupation Coding Tool

The Office for National Statistics (ONS) has an online tool that suggests appropriate SOC codes when you enter a job title. This can help narrow down options but should be validated against the Home Office table.

Method 3: Check Similar Jobs at Comparable Employers

If you’re an employer, looking at what SOC codes similar organisations have used for comparable roles can provide useful guidance. However, always validate against official sources.

Method 4: Consult an Immigration Adviser

For complex or unusual roles, a regulated immigration adviser or solicitor can advise on the most appropriate code and help draft a supporting statement to justify the classification.

Common SOC Code Mistakes and How to Avoid Them

Using Too Generic a Code

If a more specific code exists for your job, you should use it. Using a broader catch-all code when a specific one applies can:

Result in a higher going rate requirement
Lead to UKVI queries or refusal
Be seen as misrepresentation

Example: Using 2119 (Natural and social science professionals NEC) when 2136 (Programmers) more accurately describes a software developer role.

Using a Code That Doesn’t Match the Job

The SOC code must genuinely reflect what the worker will be doing day-to-day. A significant mismatch can result in compliance action against the sponsor and visa refusal or curtailment for the worker.

The Home Office considers the SOC code as a representation of the actual job. If a compliance officer reviews your sponsored workers’ roles, they’ll assess whether the code was appropriate.

Assigning the Same Code for Very Different Roles

Some employers try to use the same convenient code for multiple different roles. Each role should be classified by what that individual will actually be doing.

Not Updating the Code When a Role Changes Significantly

If a sponsored worker’s role changes substantially (different duties, department, or function), the employer may need to assign a new CoS with the appropriate new code. Failing to do so is a compliance breach.

High-Level Overview of Common Visa-Eligible SOC Codes

Here are some frequently used SOC codes in sponsorship, to give you a sense of the landscape. The figures are the standard ASHE-based going rates published on 22 July 2025, but rates and occupation eligibility can change. Always check the current figure for a specific code with our Salary Checker and the latest Home Office table before assigning a CoS.

Technology

Code	Occupation	Going Rate
2133	IT business analysts, architects and systems designers	£54,900
2134	Programmers and software development professionals	£54,700
2139	Information technology professionals NEC	£52,300
2141	Web design professionals	£43,800

Healthcare

Many health and education occupations use national pay scales rather than one ASHE figure. Current SOC 2020 examples include 2211 for generalist medical practitioners, 2212 for specialist medical practitioners, 2221 for physiotherapists and 2251 for pharmacists. Nursing is split across several codes, so match the actual duties and use the relevant pay band in the Home Office table rather than relying on a generic “nurse” rate.

Engineering

Code	Occupation	Going Rate
2121	Civil engineers	£50,400
2122	Mechanical engineers	£46,800
2123	Electrical engineers	£58,700
2125	Production and process engineers	£45,000

Finance and Business

Code	Occupation	Going Rate
2421	Chartered and certified accountants	£49,200
2422	Finance and investment analysts and advisers	£45,800
2423	Taxation experts	£48,500

These are standard-option figures for the stated reference hours. Going rates must be pro-rated for other working patterns, and discounted tradeable-points options use their own percentages.

What Happens if the SOC Code is Challenged?

If the Home Office believes the assigned SOC code doesn’t accurately reflect the job:

For visa applications: The application may be refused or a request for further information issued
For existing sponsorships: The employer may receive a compliance warning
In serious cases: The licence may be downgraded or the CoS may be curtailed

Employers should retain evidence — such as job descriptions, contracts, and organisational charts — to demonstrate why a particular code was selected.

SOC Codes and the Immigration Salary List

The ISL replaced the old Shortage Occupation List in April 2024. The old list’s 20%-below-the-going-rate concession did not carry over: under the current rules, an ISL applicant must meet both the £33,400 cash floor and the full going rate. The list is reviewed regularly and is currently due to expire on 31 December 2026.

Occupations that have appeared on shortage lists include:

Some nursing and medical SOC codes
Certain engineering roles
Some social work positions
Teaching shortage subjects

Always check the current Immigration Salary List on gov.uk for the definitive up-to-date list.

Practical Tips for Employers

Build a SOC code library — Document the codes used for each role type in your organisation
Train your HR team — Ensure those assigning CoS understand how to select appropriate codes
Review periodically — Codes and going rates are updated. Annual reviews are good practice
Document your reasoning — Keep a record of why each code was selected
Get professional advice for unusual roles — Don’t guess on complex or multi-functional positions

Conclusion

SOC codes are more than an administrative detail — they’re a fundamental part of the UK work visa framework that determines eligibility, salary requirements, and compliance obligations. Understanding them properly can mean the difference between a successful sponsorship and an avoidable refusal.

Whether you’re a job seeker wanting to know if your role qualifies, or an employer managing a sponsorship programme, taking the time to understand SOC codes correctly is always worthwhile.
