Appendix Skilled Worker Explained: An HR Guide to Reading the Rules Before Assigning a CoS

Assigning a Certificate of Sponsorship (CoS) means declaring that a role meets all Appendix Skilled Worker rules. Small mistakes, like choosing the wrong SOC 2020 occupation code or setting a salary below the going rate, lead to immediate visa refusals. Frequent errors will put your UK sponsor licence at risk. This guide helps you review the rules accurately to ensure total CoS compliance.

What is the Appendix Skilled Worker? An Overview for HR Professionals

Appendix Skilled Worker is the section of the UK Immigration Rules that sets the requirements for the Skilled Worker visa route. To secure a visa, sponsored hires must score 70 points across these categories:

• Sponsorship: Worth 20 points for having a valid job offer from an approved sponsor.
• Skill level: Worth 20 points for a job at RQF Level 3 or above.
• English language: Worth 10 points for meeting the required language proficiency.
• Salary: Worth 20 tradeable points for meeting the general threshold and going rate.

To check these requirements, you must also use Appendix Skilled Occupations. This document lists every eligible SOC 2020 occupation code and its specific minimum going rate. Always review both documents before you assign a CoS.

Why HR Teams Must Master the Skilled Worker Appendix Before Sponsorship

The Home Office holds employers responsible for sponsor compliance. Checking Appendix Skilled Worker rules before assigning a Certificate of Sponsorship (CoS) protects your organization from three costly outcomes:

• Visa refusals: The Home Office does not refund application fees or the Immigration Skills Charge for errors caused by the sponsor.
• Sponsor licence action: Submitting incorrect occupation codes or underpaying staff are the top triggers for compliance audits.
• Lost talent: A rejected application means losing a critical candidate you spent months recruiting.

┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈

Recent Changes to the Immigration Rules You Need to Know

UK immigration rules change quickly. To ensure ongoing CoS compliance, your HR team must follow these updated criteria:

• Minimum salary threshold: The standard general salary threshold is £41,700 per year.
• Higher skill level: New sponsorships require graduate-level roles at RQF Level 6 or above, unless the position qualifies under the Temporary Shortage List.
• Updated shortage lists: The Immigration Salary List and the Temporary Shortage List have replaced the old Shortage Occupation List.
• Dependant restrictions: New sponsored hires in RQF Level 3 to 5 occupations are no longer permitted to bring family dependants.
• Pay period compliance: Under paragraph SW 14.3B, employers must meet the minimum salary requirement during every individual pay cycle, not just as a yearly average.

Navigating Appendix Skilled Occupations: Are Your Roles Eligible?

Appendix Skilled Occupations determines UK visa sponsorship eligibility. If a role’s four-digit SOC 2020 code is not listed in these official tables, you cannot sponsor the position. Each entry details the specific code, standard job titles, minimum going rates,  and which table it sits in.

How to Search and Identify the Right Appendix Occupation Code

The Home Office evaluates applications based on actual job duties, not internal job titles. Caseworkers compare your Certificate of Sponsorship (CoS) job description against official Office for National Statistics (ONS) role definitions.

Step-by-Step: Matching Internal Job Descriptions to an Appendix Occupation Code

• List core duties: Focus entirely on day-to-day tasks rather than creative internal titles.
• Use ONS tools: Search the ONS SOC 2020 coding tool using these tasks to shortlist potential codes.
• Verify entry tables: Ensure your selected codes appear in the active tables of Appendix Skilled Occupations.
• Align descriptions: Select the code that best matches the majority of your role's specific duties.
• Check going rates: Record the listed minimum salary requirement for your chosen code.
• Document your logic: Maintain a clear written record of your code-matching rationale to protect against Home Office compliance audits.

Common Mistakes HR Makes When Selecting an Occupation Code

• Title-based selection: Relying on the job title instead of day-to-day responsibilities causes frequent CoS rejections.
• Salary manipulation: Choosing a lower-paying code to fit a budget triggers immediate misclassification penalties.
• Outdated reuse: Recycling old codes for promoted staff without performing a fresh duty assessment.
• Competitor copying: Adopting another company’s code without verifying if the duties align with your own vacancy.
• Ignoring updates: Failing to check if a code was removed or its going rate increased in the latest immigration rules statement.

Understanding the Appendix Shortage Occupation List

The traditional Appendix Shortage Occupation List is obsolete. It has been replaced by two separate frameworks, both scheduled to expire on 31 December 2026:

• Immigration Salary List (ISL): Features specific shortage roles that qualify for a lower general salary threshold.
• Temporary Shortage List (TSL): Grants sponsorship eligibility to medium-skilled jobs at RQF Levels 3 to 5 that would otherwise fail the graduate-level skill requirement.

┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈

What Qualifies as an Appendix Shortage Occupation?

The Migration Advisory Committee recommends occupations for both lists based on objective evidence of UK labor shortages. Businesses cannot request to add specific vacancies to these lists. Common entries include laboratory technicians, engineering trades, and specific healthcare roles.

Visa Fee Reductions and Salary Discounts for an Appendix Shortage Occupation

The financial incentives for shortage occupations are strictly limited:

• ISL roles: The general salary threshold drops to £33,400 for graduate positions or £25,000 for eligible medium-skilled roles, alongside reduced visa application fees. However, you must pay 100% of the occupation's going rate, as the old 80% going rate discount has been removed.
• TSL roles: These positions do not provide salary discounts or application fee reductions. Sponsored hires under this list are also barred from bringing family dependants. The list only serves to keep sub-degree roles eligible for visa sponsorship.
• Discount stacking: Employers cannot combine multiple tradeable points options, meaning you cannot use an ISL discount and a new entrant discount on the same Certificate of Sponsorship.

How to Check if Your Vacancy is on the Current List

To check if your vacancy is on the active shortage lists, follow these steps before assigning a Certificate of Sponsorship:

• Locate the SOC code: Find your verified four-digit job code first.
• Search gov.uk appendices: Cross-reference the code within Appendix Immigration Salary List and Appendix Temporary Shortage List.
• Review removal dates: Note the expiration columns, as most current entries expire on 31 December 2026.
• Audit before allocation: Recheck the lists immediately before assigning a CoS to catch sudden policy updates.

Salary Rules: Cross-Referencing Appendix Skilled Occupations with Pay Thresholds

UK visa sponsorship requires passing a two-part salary test. The proposed salary must meet both the general threshold (£41,700 for standard applications) and the occupation-specific going rate listed in Appendix Skilled Occupations. Sponsoring employers must pay whichever figure is higher. Visa applications fail when HR budgets solely for the general threshold and ignores a higher going rate.

┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈

Calculating the Going Rate for Your Appendix Occupation Code

The annual going rates published in the immigration rules are based on a 37.5-hour work week. To calculate the correct salary:

• Retrieve the base rate: Locate the specific annual going rate for your chosen SOC code.
• Pro-rate for hours: Adjust the salary based on the employee's contracted weekly hours.
• Check the hourly minimum: Verify that the pay equals at least £17.13 per hour, calculated up to a maximum of 48 paid hours per week.
• Compare the requirements: Contrast the pro-rated going rate against the general threshold to determine the legal minimum.

For example, a software developer role might require a going rate of £49,400. Offering £42,000 clears the £41,700 general threshold but violates the going rate, leading to an immediate visa refusal. Remember that paragraph SW 14.3B requires employers to meet these pay thresholds during every single pay period, not just as an annual average.

Allowances and Tradeable Points Explained

When calculating the UK Skilled Worker salary threshold, only guaranteed gross basic pay qualifies. The Home Office excludes bonuses, equity, pensions, and overtime from the evaluation. However, employers can use tradeable points to sponsor candidates below the £41,700 standard rate under specific conditions:

• New entrants: Sets a £33,400 minimum for applicants under 26, recent graduates, or those switching from a Graduate visa, capped at 4 years total.
• PhD holders: Lowers the requirement to £37,500 for a relevant non-STEM doctorate, or £33,400 for a STEM PhD.
• Immigration Salary List (ISL): Lowers the baseline to £33,400 (or £25,000 for select health and care roles).

Every option still requires meeting the specific percentage floor of the occupation's going rate. For a complete cost breakdown, consult our UK Skilled Worker salary threshold employer guide.

The Ultimate HR Checklist: Using the Appendix Skilled Worker Rules for CoS Assignment

‍

Run this three-step check before every Certificate of Sponsorship (CoS) assignment to ensure full compliance with Appendix Skilled Worker rules.

1. Confirm the Role Under Appendix Skilled Occupations

• Match job duties: Map day-to-day responsibilities, not corporate titles, to a SOC 2020 code using the ONS tool.
• Verify skill level: Ensure the code appears in Appendix Skilled Occupations at RQF Level 6, or holds active TSL or transitional coverage.
• Record going rates: Note the exact annual going rate and its reference table for your compliance records.

2. Verify Exemptions via the Appendix Shortage Occupation List

• Check list status: Cross-reference the active Immigration Salary List (ISL) and Temporary Shortage List (TSL) for available salary discounts.
• Review dependant rules: Confirm family visa restrictions for medium-skilled RQF 3 to 5 roles before issuing a formal job offer.
• Track expiration dates: Monitor list removal dates to safeguard future visa extensions.

3. Finalizing the CoS Application Successfully

• Audit salary criteria: Ensure the package clears the option baseline, the £17.13 hourly minimum, and the per pay period compliance rule.
• Input SMS details: Submit the exact SOC code, salary, hours, and start date into the Sponsor Management System.
• Retain sponsor records: Document your code-matching rationale and payroll data within internal files to protect your UK sponsor licence.

Our Certificate of Sponsorship guide covers the SMS assignment process step by step, and the CoS document checklist lists every record to keep on file.
