Appendix Skilled Occupations: how to pick the right SOC code at CoS assignment.
Appendix Skilled Occupations is the Home Office's list of SOC 2020 occupation codes eligible for sponsorship on the Skilled Worker route, the Global Business Mobility routes, and the Scale-up Worker route. Each SOC code has a published going rate. This is the minimum salary the Home Office expects the role to pay. To sponsor a worker, the role must be matched to a specific code on Table 1 (RQF level 6+), Table 1a (RQF 3–5, limited eligibility, with the 6135 Care worker exception at RQF 2), or Table 2 (RQF 6+). Picking the wrong code is the most common technical error we see at CoS assignment. It can cause salary, ISC and compliance problems.
Who this applies to: UK sponsors assigning a Certificate of Sponsorship to a worker. This is usually the HR lead, hiring manager or sponsor-licence key person choosing the SOC code in the SMS.
The SOC code is the decision the rest of the sponsorship hangs from.
Many employers treat the SOC code as a clerical step and pick the nearest title from a list. In practice, the code determines if the role is eligible, what the worker must be paid and where the compliance risk sits.

The five questions every sponsor should answer before SMS assignment.
There is no formula for SOC code selection. It is a judgement call, and the Home Office assesses the actual job duties rather than the title. We use the following five questions during CoS preparation.
What goes wrong when the SOC code is picked superficially.
The SMS may accept a wrong SOC code at assignment. The problem often appears later during a Home Office compliance visit, a worker's visa extension or a civil penalty review.
Where the going rate sits inside the points-based system.
Skilled Worker is a points-based route. To get the 70 points needed for the visa, the worker must score on (a) a job at the right skill level, (b) English language, and (c) salary. The salary score interacts with several discount rules that can lower the threshold for specific worker categories.
Five SOC code errors we see most often at CoS assignment.
What we do at the SOC-code decision point.
SOC code selection is exactly the kind of decision that benefits from a 30-minute regulated review before the SMS assignment is clicked. It is also the decision that, once made, is hardest to walk back. We treat it as a structured deliverable in every Skilled Worker engagement.
