UK Immigration Salary List (ISL): Eligibility, Discounts and Rules

Quick Overview

• The Immigration Salary List (ISL) contains selected occupations facing labour shortages in the UK.

  
  

• Eligible roles may benefit from reduced Skilled Worker salary requirements.

  
  

• Employers must still meet the applicable going rate for the occupation.

  
  

• Eligibility depends on the correct SOC 2020 occupation code.

  
  

• Not every job within a listed occupation qualifies.

  
  

• The list is reviewed and updated periodically by the UK Government.

  
  

Why the Immigration Salary List Matters

Recruiting international talent has become increasingly important for many UK businesses.

From construction firms struggling to source skilled tradespeople to laboratories seeking specialist technicians, some sectors face persistent workforce shortages that cannot be filled quickly through domestic recruitment alone.

The Immigration Salary List was introduced to help address these gaps by allowing certain occupations to benefit from lower salary thresholds under the Skilled Worker route.

For employers, this can widen the recruitment pool.

For overseas workers, it can create sponsorship opportunities that might otherwise be unavailable.

However, inclusion on the list does not guarantee visa approval. Sponsorship, salary compliance, and immigration eligibility requirements must still be satisfied.

How to Check Whether Your Job Is Eligible

Eligibility is determined by the nature of the role and the duties you will be carrying out, rather than the job title alone. Job titles can vary significantly between employers, so the Home Office assesses whether a role is eligible by considering the actual responsibilities of the position and matching them to the relevant occupation code.

When assessing eligibility, it is important to review the job description and main duties to ensure they align with an eligible occupation code.

Step 1: Identify Your SOC Code

The UK immigration system uses SOC 2020 (Standard Occupational Classification) codes to categorise occupations.

Two people with similar job titles may fall under completely different SOC codes depending on their duties and level of responsibility.

The first step is therefore to identify the correct occupation code using official guidance and job descriptions.

Step 2: Review Current Immigration Rules

Once the SOC code has been identified, compare it against the latest Immigration Salary List published within the Immigration Rules.

The list is updated periodically and can change following recommendations from the Migration Advisory Committee (MAC).

Step 3: Check Any Role-Specific Restrictions

Some occupation codes are only partially eligible. In these cases, only certain job functions, specialisms, or locations within the occupation may qualify.

For example, occupation code 2111 – Chemical Scientists is only eligible where the role is in the nuclear industry and based in Scotland. A Chemical Scientist working outside the nuclear industry or elsewhere in the UK would not qualify under this occupation code for ISL concessions.

Always check the full occupation code description and any accompanying notes before concluding that a role is eligible.

Step 4: Confirm Salary Requirements

Being on the ISL does not automatically mean a lower salary can be offered.

In most cases, the employer must still pay whichever is higher:

• The discounted Skilled Worker salary threshold (£33,400 per year); or

• The applicable going rate for the occupation code.

  
  

The going rate is usually expressed as both an annual salary and an hourly rate. The salary offered must meet both requirements, meaning it must satisfy the relevant annual salary threshold and the minimum hourly rate.

Example

2112 – Biological Scientists

The going rate is £40,300 per year based on a 37.5-hour working week, or £20.67 per hour, whichever is higher.

As the going rate is higher than the discounted ISL threshold of £33,400, the employer must pay at least £40,300 per year (and meet the hourly rate requirement).

2142 – Graphic and Multimedia Designers

The going rate is £33,400 per year based on a 37.5-hour working week, or £17.13 per hour, whichever is higher.

As the annual going rate is the same as the discounted ISL threshold, an employer offering a 37.5-hour working week may pay a salary of £33,400 per year, provided the hourly rate requirement is also met.

Important

All going rates are based on a standard working week and must be pro-rated if the contracted weekly working hours differ. For example, if an employee works more or fewer than 37.5 hours per week, the annual salary requirement must be adjusted accordingly while still meeting the applicable hourly rate.

However, reducing the weekly working hours does not allow an employer to pay less than the discounted Skilled Worker salary threshold. Even where the pro-rated going rate falls below £33,400, the salary must still meet the minimum discounted Skilled Worker threshold of £33,400 per year (unless a different salary rule applies under the Immigration Rules).
