TL;DR: The Skilled Worker visa route restricts eligibility to specific occupations identified by SOC 2020 codes. Sponsors must verify that a role appears on the eligible-occupation list, check whether the Immigration Salary List applies, and issue a Certificate of Sponsorship only for qualifying positions.
Introduction: Why the Eligible-Occupation List Is Central to the Skilled Worker Route
The Skilled Worker visa is not an open-door route for any job in the UK labour market. At its core, the route is governed by a tightly defined list of Skilled Worker eligible occupations, each assigned a Standard Occupational Classification (SOC) 2020 code. Understanding how these codes work — and how they interact with minimum salary thresholds and the Immigration Salary List — is essential for both licensed sponsors and prospective applicants navigating the route.
Published by the Home Office and maintained by UK Visas and Immigration (UKVI), the eligible-occupation list sets out every job type that can legitimately be sponsored under the Skilled Worker route. A role that does not appear on this list cannot be used as the basis for a Certificate of Sponsorship (CoS), regardless of salary or skill level. For employers holding a Sponsor Licence, the list is a foundational compliance document — not an optional reference.
This guide provides a detailed, authoritative breakdown of how SOC 2020 codes determine eligibility, how the Immigration Salary List modifies salary requirements for certain roles, and what sponsors must verify before issuing a CoS.
What Are Skilled Worker Eligible Occupations?
Skilled Worker eligible occupations are the specific job roles formally approved by the Home Office for sponsorship under the Skilled Worker visa route. Each eligible occupation is identified by a unique SOC 2020 code — a four-digit classification drawn from the Office for National Statistics’ Standard Occupational Classification framework. Only roles listed in the official eligible-occupations publication at gov.uk qualify for sponsorship, and each carries an associated minimum salary threshold that sponsors must meet or exceed.
How SOC 2020 Codes Determine Visa Eligibility
The Structure of the SOC 2020 Framework
The SOC 2020 system, developed by the Office for National Statistics, classifies all occupations in the UK economy into a hierarchical structure of major groups, sub-major groups, minor groups, and unit groups. For immigration purposes, it is the four-digit unit group code that matters most.
Each unit group represents a cluster of closely related job titles. For example, SOC code 2135 covers IT business analysts, architects and systems designers, while SOC code 6145 covers care workers and home carers. When a sponsor assigns a SOC code to a sponsored worker’s role, they are asserting that the worker’s day-to-day duties correspond to that occupational classification.
The Home Office cross-references the assigned SOC code against the eligible-occupation list to determine whether the role qualifies for the Skilled Worker route. If the code does not appear on the list, the application will be refused at the CoS assignment or visa application stage.
Mapping Job Titles to SOC Codes
One of the most common compliance errors made by sponsors involves incorrectly mapping a job title to a SOC code. Job titles can be misleading — a “manager” in one organisation may perform duties more consistent with a technical specialist code, and vice versa. The Home Office expects sponsors to assess the actual duties of the role, not simply the job title used internally.
UKVI provides guidance through the eligible-occupations spreadsheet, which lists each qualifying SOC 2020 code alongside example job titles and the applicable minimum salary threshold. Sponsors are expected to cross-reference this document carefully before assigning a code.
Key Rule: A Certificate of Sponsorship must reference a SOC 2020 code that accurately reflects the genuine duties of the role. Misclassification — even if unintentional — may constitute a breach of sponsor duties and can trigger a UKVI compliance visit.
Skill Level Requirements
The Skilled Worker route is restricted to roles classified at RQF Level 3 or above (broadly equivalent to A-level standard). The eligible-occupation list effectively pre-filters the SOC 2020 framework to include only those unit groups that meet this threshold, removing lower-skilled occupations from the route entirely. Sponsors do not need to independently assess skill level — if the SOC code appears on the eligible-occupation list, the skill-level requirement is considered met for that occupation.
The Immigration Salary List: How It Interacts With Eligible Occupations
What Is the Immigration Salary List?
The Immigration Salary List (ISL) — which replaced the former Shortage Occupation List in April 2024 — is a subset of the broader eligible-occupation list. It identifies specific SOC 2020 codes where a discounted salary threshold applies, reflecting roles where the Home Office has accepted evidence of recruitment difficulty or structural workforce need.
For occupations on the ISL, the applicable going rate is reduced. As of the April 2024 changes, roles on the ISL attract a 20% discount on the going rate for that occupation, though the general salary floor still applies. This means sponsors assigning an ISL occupation code may offer a lower salary than would otherwise be required — but salary floors set by the general Skilled Worker threshold rules still constrain the minimum permissible figure.
How the Discount Mechanism Works in Practice
For a role on the Immigration Salary List, the minimum salary is the higher of:
- The general salary threshold for the Skilled Worker route (as set by current immigration rules); or
- 80% of the going rate for that specific SOC code.
Important: Inclusion on the Immigration Salary List does not change the occupational eligibility of a role. The ISL is a salary-adjustment mechanism only — the underlying SOC 2020 code must still appear on the eligible-occupation list for the role to qualify for sponsorship.
Sponsors should not conflate the ISL with a general shortage designation. The Migration Advisory Committee (MAC) periodically reviews and updates the ISL, and codes may be added or removed following MAC recommendations. Sponsors are advised to check the current published version of both documents when preparing a CoS.
Occupations Not on the Immigration Salary List
For the majority of Skilled Worker eligible occupations — those not appearing on the ISL — the full going rate applies. Sponsors must pay the higher of the general salary threshold or the going rate for the relevant SOC code as published in the eligible-occupations list. There is no discretion to apply a discount for non-ISL roles.
Why Does the Eligible-Occupation List Matter for Compliance?
The CoS Assignment Obligation
Before assigning a Certificate of Sponsorship, a licensed sponsor must confirm three things in relation to occupational eligibility:
- The SOC 2020 code assigned to the role appears on the current eligible-occupation list.
- The salary offered meets or exceeds the applicable threshold for that code (including any ISL adjustment where relevant).
- The job duties genuinely correspond to the assigned SOC code — not merely the job title.
Failure to satisfy any of these conditions risks CoS refusal, visa refusal, or — in cases of deliberate misrepresentation — suspension or revocation of the Sponsor Licence.
Changes to the Eligible-Occupation List Over Time
The eligible-occupation list is not static. The Home Office updates it following MAC reviews, changes to immigration policy, or amendments to the SOC framework itself. Sponsors should treat the list as a living document and verify they are consulting the most recent published version at the time of CoS assignment. Historic versions of the list are archived on gov.uk but do not govern current applications.
Implications for Sponsors and Employers
Licensed sponsors carry direct legal responsibility for ensuring every CoS they assign references a valid, correctly mapped SOC 2020 code from the current eligible-occupation list. This obligation forms part of the broader sponsor duties framework and is subject to audit by UKVI compliance officers.
Employers operating in sectors with evolving job structures — technology, healthcare, engineering — should periodically audit their sponsored workforce’s SOC code assignments to ensure ongoing accuracy. Where a worker’s duties have materially changed since the original CoS was assigned, sponsors may need to issue a new CoS with a corrected code and verify that salary conditions remain compliant.
Recruitment teams and HR professionals involved in the sponsorship process should receive training on SOC 2020 mapping to reduce the risk of inadvertent misclassification, which remains one of the most frequently cited issues in UKVI compliance reviews.
Frequently Asked Questions
Q: How can sponsors check whether a job role is on the Skilled Worker eligible-occupation list? A: The Home Office publishes the eligible-occupation list as a downloadable spreadsheet on gov.uk. The document lists every qualifying SOC 2020 code alongside example job titles, the applicable going rate, and whether the occupation appears on the Immigration Salary List. Sponsors should consult the most recent version before assigning any Certificate of Sponsorship.
Q: What happens if a sponsor assigns the wrong SOC 2020 code on a Certificate of Sponsorship? A: Assigning an incorrect SOC code can result in visa refusal if the correct code is not on the eligible-occupation list, or in a salary-compliance breach if the going rate for the correct code is higher. Persistent or deliberate misclassification may constitute a breach of sponsor duties, potentially leading to a downgrade or revocation of the Sponsor Licence.
Q: Does appearing on the Immigration Salary List make a role automatically eligible for the Skilled Worker visa? A: The Immigration Salary List is a subset of the eligible-occupation list, so all ISL roles are eligible for sponsorship. However, inclusion on the ISL only affects the applicable salary threshold — it does not create eligibility independently. The underlying SOC 2020 code must still appear on the eligible-occupation list.
Q: Can a sponsor use a SOC 2020 code for a job title that does not exactly match the examples in the eligible-occupation list? A: Yes — the example job titles in the eligible-occupation list are illustrative, not exhaustive. The decisive factor is whether the actual duties of the role correspond to the occupational description for that unit group. Sponsors should document their rationale for the assigned code in case of a UKVI compliance query.
Q: How often is the Skilled Worker eligible-occupation list updated? A: The list is updated periodically, typically following recommendations from the Migration Advisory Committee or changes to immigration rules. There is no fixed publication schedule. Sponsors should check the gov.uk publication page regularly to ensure they are using the current version.
Key Takeaways
- The Skilled Worker route is restricted to specific occupations identified by SOC 2020 codes on the Home Office eligible-occupation list.
- Each qualifying SOC code carries an associated going rate; sponsors must pay the higher of this rate or the general salary threshold.
- The Immigration Salary List provides a 20% going-rate discount for designated occupations but does not alter underlying eligibility rules.
- Sponsors must ensure the assigned SOC code accurately reflects the genuine duties of the role — not merely the job title.
- The eligible-occupation list is updated periodically; sponsors should always consult the current published version on gov.uk before issuing a Certificate of Sponsorship.
Conclusion
The eligible-occupation list and SOC 2020 framework are foundational elements of the Skilled Worker visa route. For licensed sponsors, accurate code assignment is both a legal obligation and a critical compliance risk. Understanding how the Immigration Salary List modifies threshold requirements — and recognising its limits — is equally important. The Home Office publishes all relevant documentation on gov.uk, and sponsors are expected to remain current with updates as the list evolves. Applicants and employers seeking detailed, role-specific information should consult the official eligible-occupations publication directly.
