SOC Code Guide for Employers 2026

# What UK employers need to know about SOC codes in 2026

A SOC code is the four-digit Standard Occupational Classification used to describe the job a sponsored worker will do. Employers now use SOC 2020 codes when assigning a Certificate of Sponsorship (CoS). Under the Skilled Worker route and several other sponsored work routes (for example Global Business Mobility and Scale-up), the chosen SOC code determines both eligibility and which salary rules apply.

• The code must reflect the worker's actual duties and responsibilities. Job titles alone are not decisive.
• Decide the likely SOC code early in recruitment and confirm it before issuing the CoS.

Identify the SOC code when scoping and designing the role, and before sponsorship eligibility, salary and the employment offer are signed off. Waiting until the CoS stage increases risk because the candidate may already have accepted the role and the business may have set start dates contingent on sponsorship outcomes. Early checking avoids having to redesign the role, change salary or move the start date after expectations are set.

The correct code is the one that best matches the duties the person will actually perform. Employers should:

• Read the SOC 2020 occupation descriptions and compare them to the role's written duties.
• Use coding tools such as CASCOT to generate candidate codes.
• Prefer duties-based matching over job titles, since titles vary across businesses.

Statistics (ONS) publishes the SOC 2020 coding index and occupation descriptions employers can use to verify the fit.

The SOC code affects whether a role is eligible for sponsorship and which minimum salary applies under the immigration rules. An incorrect or weak classification can lead UKVI to question the occupation code, ask for supporting information, or reject the application. Misclassification can also cause problems later when the worker seeks an extension, changes role or applies for settlement.

Practical recordkeeping and evidence

Record the decision process: the duties considered, the SOC 2020 descriptions compared, CASCOT outputs if used, and the rationale for choosing the final code. If UKVI asks for evidence, employers should be able to show the job description, contracts, and any internal role documentation that aligns with the chosen occupation code.

SOC 2020 codes are used across several sponsored work routes, but eligibility lists and salary rules vary by route. Employers should check the specific rules for the route they plan to use rather than assuming the code's implications are identical across routes.

Select the SOC 2020 code that most closely matches the worker's real duties, confirm it early, document the decision, and be ready to support it with evidence if UKVI questions the classification. Doing so reduces sponsorship risk at application and in later extensions or settlement applications.
