Knowing how to check UK Skilled Worker occupation codes can save you from applying for unsuitable vacancies, misunderstanding salary requirements or accepting misleading sponsorship promises. A job title that sounds professional does not automatically make the job eligible for sponsorship. The actual duties and the relevant immigration rules matter.
An occupation code is one part of the assessment. You also need to consider the employer, salary, working hours, any restrictions attached to the occupation and your own circumstances. Finding a number in a government table is a useful beginning, but it is not a visa approval.
This guide takes you through a practical checking process. It explains where to search, how to compare similar occupations, what to ask an employer and how to record your findings. It is written for applicants researching from Nigeria and other countries, as well as readers already in the UK who need to understand a proposed role.
The aim is to help you ask better questions before you commit money, resign from a job or submit an application. You do not need to memorise hundreds of occupation codes. You need a reliable method for checking the particular work you expect to do.
Important: This article provides general educational information, not personalised immigration or legal advice. Immigration rules and occupation classifications can change. Check the current official sources and obtain appropriate regulated advice where necessary. Spreemkt does not assign sponsorship codes, issue Certificates of Sponsorship or guarantee jobs or visas.
1. What Is a UK Skilled Worker Occupation Code?
For this route, an occupation code is a four-digit classification identifying a group of jobs. It connects a proposed position with the occupational categories used in the sponsorship system.
The relevant framework is the Standard Occupational Classification, commonly shortened to SOC. Current sponsor guidance explains the use of SOC 2020 for Certificates of Sponsorship assigned from 4 April 2024, replacing the earlier SOC 2010 system for those assignments.
An occupation code is different from a vacancy reference, payroll number, professional registration number or sponsor licence number. Those identifiers answer different questions. A vacancy reference identifies an advertised opening; an occupation code identifies the occupational category of the work.
The official sponsor guidance on sponsoring a worker explains the sponsor’s obligation to specify the relevant code when assigning sponsorship. Your research helps you understand that choice and notice questions that need clarification.
2. Why the Correct Code Matters
The code helps determine which eligibility and salary provisions need to be examined. An error can therefore affect much more than a single field on an application form.
Imagine comparing two vacancies with similar titles. One involves independent professional responsibilities; the other mainly involves routine assistance. Treating them as identical because both adverts contain the word “specialist” can lead you to the wrong conclusion about sponsorship.
Your practical objective is to establish a consistent account of the work. The advert, job description, employer explanation and sponsorship information should describe the same role. A code that appears unrelated to that role needs explanation before you rely on it.
Do not begin by asking which code offers the easiest immigration outcome. Begin by asking what work is actually being offered. Once that is clear, you can investigate the classification and applicable requirements without distorting the job to fit a preferred result.
3. Start With the Job, Not Your Degree
Your qualifications and experience are important when applying for employment, but a degree subject does not automatically determine the occupation code of every job you might obtain.
A person with an engineering degree might apply for design work, technical sales, project administration or a role outside engineering entirely. The qualification alone cannot tell you how each proposed position should be classified.
Write down what the employer expects you to do during a normal working week. Identify the main outputs, the decisions you will make and the responsibilities for which you will be accountable. This makes the occupation search much more focused.
Also separate the position you want from the position actually offered. A junior support vacancy does not become a senior professional role because you have extensive experience. If your skills exceed the job requirements, you can negotiate or search for another role, but the classification still needs to reflect the actual work.
4. Gather the Information You Need Before Searching
Request the full job description where one is available. A short social media advert rarely provides enough detail for a dependable classification comparison.
Collect the job title, department, main duties, reporting line, working location, weekly hours and proposed salary. Ask whether the work involves supervision, budget responsibility, specialist judgement, professional registration or practical technical tasks.
For an agency vacancy, establish who the actual employer will be and who can explain the position. A recruiter’s sales summary may omit details that the employer considers central to the role.
Create a short factual outline in your own words. For example, describe the systems maintained, the customers served or the technical problems solved. Avoid inserting duties simply because you think they make the job sound more eligible. Accurate preparation gives you something concrete to compare with the official occupational descriptions and something useful to send back when asking the employer for clarification.
5. Ask the Employer for Its Proposed Code
If you already have an offer, ask the employer which SOC 2020 occupation code it proposes to use. Request the four-digit number and the corresponding occupation description, rather than accepting a statement that the role is generally “on the list”.
Keep the question neutral. You are trying to understand the proposed sponsorship, not suggesting that you have authority to override the employer’s assessment.
A useful follow-up is to ask how the principal duties fit the selected category. You can also ask which salary provisions the employer has used and whether any special eligibility conditions apply.
If the recruitment contact does not know, ask who within the organisation handles sponsorship. Large employers may have a dedicated team, while smaller businesses may use professional advisers. Do not pressure an uninformed recruiter to invent an answer. Wait for information from someone able to explain the actual sponsorship arrangement.
6. Open the Official Eligible Occupations Table
Use GOV.UK’s Skilled Worker eligible occupations and codes table. Check that you are viewing the genuine government page rather than a copied list or an old screenshot.
The table provides occupation numbers, job categories, related titles and eligibility labels. It is arranged numerically, so searching within the page can be faster than scrolling through the whole document.
On a desktop browser, use the page-search function. On a phone, look for the browser’s “Find in page” option. Search the four-digit number if you have it, and examine the complete row instead of stopping at the first highlighted word.
Record what you find, including the date you checked. A saved note is useful for discussion, but the live official page remains important when you return later. Do not assume a downloaded copy reflects changes made after you saved it.
7. Search Full Words and Alternative Job Titles
If your exact title does not appear, try a clear description of the occupation and sensible alternatives. Employers use different titles for similar work, and a table cannot include every internal company label.
For example, a vacancy advertised with an abbreviation may be easier to research using the full occupational term. GOV.UK specifically encourages readers to try similar titles and full words when searching its table.
Search one concept at a time. Very long phrases copied from an advert may produce no result even when a relevant occupational category exists. Conversely, a broad word may highlight many unrelated rows.
Keep a shortlist of plausible matches rather than choosing the first result. Write down why each category might fit and what information is missing. That comparison gives you a better basis for an employer enquiry than simply saying that an online search returned a particular number.
8. Use CASCOT as a Classification Aid
GOV.UK links to the CASCOT occupation coding tool for readers who need help identifying a code. Reach the tool through the link on the official job-eligibility page so that you are using the resource the government signposts.
Treat the output as a research aid. A suggested classification does not confirm that a sponsor will use it, that your exact position is eligible or that you meet the route’s other conditions.
Use the most accurate occupational description you have. A vague entry such as “manager” provides less useful context than a description of the actual function. Explore plausible alternatives if the wording produces an unexpected result.
Save your search terms and the result you reviewed. This helps you explain the basis of your question to the employer. Do not present a tool suggestion as an official decision about your individual visa application or as a substitute for sponsor responsibility.
9. Compare Duties, Responsibility and Working Context
Read the description behind a plausible category and compare it with the real role. Look beyond shared words and ask whether the work has the same central purpose.
Consider what you produce, how independently you work, whether you manage people or resources and which duties occupy most of your time. A title containing “lead” might describe formal leadership in one company and customer-facing coordination in another.
The Home Office caseworker guidance explains that sponsors should select the closest-fitting code, including consideration of the duties occupying the most time where more than one choice is plausible.
An occasional specialist task should not automatically define an otherwise different position. If an advert is unclear, ask for a realistic breakdown of the work. Use that information to understand the classification rather than trying to make a persuasive title do the work of a proper job description.
10. Use ONS Material When Titles Are Ambiguous
The Office for National Statistics publishes the SOC framework and supporting classification material. Its SOC 2020 coding index and conventions can help explain how occupational titles are organised.
This is useful when a company title is unusual or several categories appear similar. Read the surrounding classification information instead of assuming that a keyword search alone settles the issue.
ONS material explains occupational classification; it is not a separate immigration permission system. After researching a possible code there, return to the relevant GOV.UK immigration sources to check its use for the Skilled Worker route.
Avoid confusing a broad occupational group with the specific four-digit code requested for sponsorship. Write down the full identifier and description. If two sources appear inconsistent, note their dates and ask the employer or an appropriately regulated adviser to resolve the question before an application is submitted.
11. Understand Higher Skilled, Medium Skilled and Ineligible Labels
The eligible occupations table uses three labels: Higher Skilled, Medium Skilled and Ineligible. Read the label attached to the specific row, then investigate the conditions relevant to that category.
Higher Skilled does not mean that every applicant with an offer in that category qualifies. It addresses the occupation classification; sponsorship, pay and other application requirements still need checking.
Medium Skilled should prompt further investigation rather than an automatic yes or no. The current framework contains additional routes to eligibility and restrictions that depend on the role and applicant’s circumstances.
Ineligible means you should not assume the proposed position can be sponsored under this route simply because the work is valuable or the employer is keen to hire. Ask for clarification if the sponsor claims otherwise, including the exact current provision relied upon. Respect for an occupation’s contribution to society is separate from its treatment under a particular immigration route.
12. Check Shortage Lists and Additional Conditions
Where a role’s eligibility depends on a shortage provision, use the live Temporary Shortage List publication and Appendix Immigration Salary List, as applicable.
Read the entire entry. Some provisions concern only particular jobs within a code or work in a specified part of the UK. A matching number is not enough if your position does not satisfy the accompanying wording.
Check any dates and the event to which a date refers. A rule about sponsorship assignment is not necessarily the same as a deadline for submitting an application or starting employment. If the wording is unclear, ask for advice rather than guessing.
Avoid relying on an old “shortage jobs” graphic shared in a group chat. Record the exact provision and why the employer believes it applies. Lists and restrictions can change, so recheck them before proceeding with a time-sensitive sponsorship decision.
13. Identify Whether Transitional Rules May Matter
Someone making a first application from abroad may be in a different position from a worker already holding permission under earlier rules. A friend’s successful application is therefore not a complete guide to your own eligibility.
The Immigration Rules Appendix Skilled Worker contains detailed provisions, including conditions connected with earlier sponsorship and continuing permission. Establish the relevant history before assuming a transitional provision applies.
Collect the dates and records you actually have: previous sponsorship information, applications and grants of permission where relevant. Do not substitute an approximate memory of when you first discussed a job with an employer.
If the employer mentions transitional protection, ask which provision it is relying on and which facts establish your eligibility. Keep that explanation with your records. This is an area where individual advice can be valuable because a small difference in immigration history may change which rules need to be considered.
14. Keep Occupation Eligibility Separate From Salary Eligibility
Once you identify a plausible eligible occupation, begin a separate salary check. A role can fit an occupational category while the proposed pay still fails the applicable requirements.
At the review date, GOV.UK states that the usual standard salary requirement is the higher of £41,700 annually and the occupation’s going rate. Other provisions can apply, so that figure is not a universal answer for every applicant.
Think of the checks as separate questions: is this the correct classification, is it available in these circumstances and is the pay sufficient under the relevant rules? Passing one question does not remove the others.
Ask the employer to explain its comparison in writing. This is particularly useful where the offered package includes variable pay, additional hours or benefits. An attractive total compensation figure in an advert is not necessarily the same figure used for immigration salary assessment.
15. Find the Going Rate for the Correct Code
Open the official Skilled Worker going-rates table and search for the same four-digit code you have been checking.
Read the heading and explanatory notes before using a salary figure. Where different columns appear, establish which one applies to your circumstances. You cannot simply select the lower number because it is closer to the employer’s offer.
Write down the code, occupation description, column used and listed amount. Then record the hours on which that rate is based and the weekly hours proposed by the employer.
Use the official table for orientation and consult the relevant Immigration Rules where a case involves special provisions. If you see an inconsistency between a summary page and detailed current rules, do not choose whichever answer is more convenient. Ask the sponsor to resolve it with the applicable provision and effective date clearly identified.
16. Account for Weekly Hours Correctly
Pay comparisons can be misleading when working hours differ. The going-rates guidance explains that its listed annual amounts are based on a 37.5-hour week and need adjustment for other patterns, while some occupation-specific arrangements use different bases.
For a purely fictional illustration, suppose a relevant rate is £45,000 for 37.5 hours and the proposed job is 40 hours weekly. Applying a straightforward proportional calculation would give £45,000 multiplied by 40 divided by 37.5, which equals £48,000.
Those figures are invented arithmetic, not the current requirement for any particular occupation. The example shows why weekly hours matter; it is not an application assessment.
Do not assume that every separate salary threshold reduces proportionally for part-time work. Ask the sponsor to explain both the hours adjustment and any applicable minimum that remains. Keep the calculation with the relevant source notes so you can see exactly what was compared.
17. Understand Salary Exceptions Without Assuming You Qualify
GOV.UK provides separate guidance on when an applicant can be paid less. Certain circumstances can support different salary treatment, but each has specific conditions.
For example, references to new entrants or relevant qualifications are not invitations to choose a discount without evidence. The employer needs to identify the applicable basis and check all relevant conditions, including any limits.
Being new to a company is not, by itself, proof of qualifying as a new entrant under immigration rules. Likewise, having a postgraduate qualification does not automatically establish eligibility for every qualification-related provision.
Ask what evidence supports the employer’s calculation and how long the proposed treatment can apply. If you do not understand the answer, request clarification before relying on the lower figure. A salary exception should be a documented conclusion about the rules and your circumstances, not a reassuring phrase added to an otherwise unexplained offer.
18. Check Healthcare and Education Provisions Separately
Some healthcare and education occupations have salary arrangements linked to national pay scales. The government’s healthcare and education salary guidance explains this separate approach and links to the relevant occupations and scales.
Do not assume every job in a hospital, care business, school or university uses the same salary rules. An organisation can employ people in many different occupational categories, including administrative, technical and professional roles.
Identify the actual occupation first. Then check whether the particular pay-scale provisions apply, including any relevant location, grade or employment details. Ask the employer to explain the scale point used in its calculation.
Professional registration is another separate question. An immigration classification does not itself grant permission to practise a regulated profession. If registration is required for your work, investigate that process through the appropriate professional body rather than treating the occupation-code search as a substitute for professional recognition.
19. Use Appendix Skilled Occupations Carefully
Appendix Skilled Occupations is the detailed rules resource covering occupational entries and rates for several sponsored routes. Its tables and notes need to be read in the context of the route and provisions applying to you.
Do not assume that any appearance of a code anywhere in the Appendix establishes eligibility for your proposed Skilled Worker application. The document also concerns other routes, and different tables can apply in different circumstances.
Before using an entry, read the table heading, route abbreviations, notes and relevant cross-references. Record why that particular table applies, rather than copying a number out of context.
This is especially important when an online article links directly to an isolated row. Open the full official page and inspect the surrounding explanation. If the rules are difficult to interpret, ask the sponsor or an appropriately regulated adviser to explain the relevant chain of provisions in plain language.
20. A Fictional Walkthrough: Researching a Technical Role
Imagine an applicant in Abuja receives an advert for a “digital systems specialist”. The title is broad, and the advert mentions supporting users, maintaining systems and helping with improvements. This is a fictional example, not an assessment of an actual vacancy.
The applicant first asks for the full job description. It becomes clear that most of the position concerns responding to user problems and routine support, while development work is occasional. That detail matters when comparing possible occupational categories.
The applicant asks the employer for its proposed code and researches the description through the official resources. Instead of deciding that the word “specialist” proves a professional classification, the applicant asks how the day-to-day duties support the proposed choice.
Only after that discussion does the applicant investigate the code’s current eligibility conditions and salary rules. The example demonstrates a method, not a particular coding result. Similar titles can describe substantially different jobs, so the answer must follow the real duties.
21. A Fictional Walkthrough: An Offer Above the General Threshold
Consider another invented example. An employer offers £44,000 for a role whose applicable going-rate requirement, after the relevant checks, would be £47,000. These are illustrative amounts and are not attached to a real occupation code.
The applicant notices that the offer exceeds the usual general threshold and assumes the salary issue is settled. The comparison is incomplete because the occupation-specific requirement still matters.
The useful next step is to ask the employer how its salary assessment works. There may be a misunderstanding about the applicable table, the working hours or whether a valid exception exists. The applicant should obtain an explanation rather than attempting to solve the difference by choosing another occupation code.
If no applicable provision supports the salary, the employer may need to reconsider the offer or the sponsorship proposal. The applicant should not treat a mismatch as a harmless formality. Understanding the calculation early allows the parties to address a substantive issue before submission.
22. Keep a Simple Occupation-Code Research Record
A written record reduces confusion when you compare vacancies or speak with several recruiters. Use one record for each actual position, rather than keeping a single “my code” note for every application.
| Item | What to record | Why it matters |
|---|---|---|
| Employer and vacancy | Legal employer, role and vacancy reference | Keeps different offers separate |
| Actual duties | Main tasks, responsibility and working context | Supports a meaningful comparison |
| Proposed code | Four-digit number and description | Identifies the category being discussed |
| Eligibility | Label and applicable additional conditions | Avoids assuming every listed role qualifies |
| Source | Official page and date checked | Makes later review easier |
| Salary basis | Relevant table, column and rate | Shows which requirement was used |
| Working hours | Contracted weekly hours | Supports the correct comparison |
| Employer explanation | Contact and written clarification | Records unresolved questions |
Mark uncertain items as “not confirmed”. A blank space should not silently become an assumption. Review the record whenever the employer changes the duties, hours, salary or proposed sponsorship details.
23. What to Do When Two Codes Seem Plausible
Some jobs genuinely combine responsibilities. Start by listing the main duties and their importance rather than arguing from the title alone. Identify what the employer is hiring you principally to accomplish.
Compare each plausible category with that description. Note which tasks fit well and which appear outside its scope. Ask the employer to explain why it prefers one classification over the other.
The caseworker guidance acknowledges that more than one code can be plausible, while warning against exaggerated or inappropriate coding. Your goal is a defensible fit, not an artificially certain answer produced by ignoring awkward details.
Do not rewrite the job description yourself to remove responsibilities that complicate the result. If the actual role is changing, ask for an accurate revised description and renewed assessment. Where the distinction remains difficult and materially affects sponsorship, obtaining appropriate professional advice is more useful than collecting conflicting opinions from anonymous online discussions.
24. What If Your Employer’s Code Looks Wrong?
Raise the issue respectfully and provide specific information. Explain which duties you believe need closer consideration and which official descriptions prompted your question.
Avoid assuming deliberate misconduct. A difference may arise because you have an incomplete description, the recruiter used an informal title or the employer has information you have not seen. Give the relevant sponsorship contact an opportunity to clarify.
If the explanation remains inconsistent, ask whether the assessment can be reviewed before sponsorship or application steps continue. Do not alter an application answer independently while leaving the employer’s information unchanged.
If a Certificate of Sponsorship has already been assigned, ask the sponsor how any necessary correction must be handled through the proper process. You should not guess whether an informal email is sufficient for a particular error. Keep records of the issue and seek regulated advice where the consequences are unclear or the sponsor pressures you to proceed despite unresolved concerns.
25. Check Sponsorship and Offer Authenticity Separately
An eligible occupation code does not prove that an employer has a sponsor licence or that a recruiter represents it. It also does not establish that the advertised vacancy is genuine.
Verify the employer independently and confirm the specific role through a genuine company channel. Treat the code as information about a proposed occupation, not as an authentication stamp on a job offer.
Spreemkt’s guide on verifying a UK employer’s sponsorship licence explains that separate checking process. Its guide to identifying fake overseas recruitment agencies covers recruiter identity, payment demands and document safety.
Be especially cautious when someone says you must pay to obtain a better code or claims a code guarantees approval. Ask what actual service is being offered and verify any claimed requirement. Never supply false work history or accept invented duties because an intermediary presents them as the normal way to secure sponsorship.
26. Review Your Application Information Before Submission
The government’s Skilled Worker document guidance identifies occupation code, job title, salary and sponsor information among the details needed for an application. Ask your employer for the relevant sponsorship information if you do not have it.
Compare the details with your offer and the explanations you have received. Check numbers carefully, especially if someone has copied them between documents. A transposed digit can be easy to miss when you recognise only part of the description.
Do not treat checking as a substitute for truthful disclosure. Your employment history, qualifications and proposed work should be described accurately throughout the application.
Make a list of unresolved questions before you submit rather than relying on an intention to explain later. Where an adviser is involved, ask to understand the information being submitted in your name. You should be able to identify the role, code and salary basis without depending entirely on an intermediary’s verbal assurances.
27. Recheck the Code When the Job Changes
A promotion, move to another employer or substantial change in responsibilities can raise new immigration questions. Do not assume the code researched for your original offer remains suitable for every later role.
GOV.UK’s guidance on updating a visa after a job or employer change explains circumstances in which an updated application is needed, including relevant occupation-code changes and exceptions.
Before agreeing to a change, ask the employer’s sponsorship contact to review the proposed duties, salary and timing. A new title alone may not tell you whether the classification changes, and unchanged branding does not mean an altered job is identical.
Keep the original and revised job descriptions so that the difference is clear. Seek advice before beginning work that may require new permission. An internal employment decision and the immigration permission needed for that work are connected questions, but they should not be treated as automatically identical.
28. Common Mistakes That Make Searches Less Reliable
One frequent mistake is copying a code from a friend’s visa without comparing duties. Another is treating an old online list as current because it ranks highly in a search engine.
Applicants also confuse a salary figure with complete eligibility, select a lower-rate column without checking its conditions or assume a professional qualification determines the code. Each shortcut skips a different part of the assessment.
Another problem is treating every disagreement as evidence of fraud. Codes can require interpretation, and a responsible employer may need time to obtain advice. Ask for evidence and a clear explanation before drawing conclusions.
Finally, avoid spending hours researching a vague advert when the employer has not supplied the essential job details. Begin with a factual description, then investigate. A careful search cannot compensate for missing information about what you would actually be employed to do. Resolve that gap before treating any result as dependable.
29. Frequently Asked Questions
You can research likely categories based on the kind of work you seek. Treat the result as preparation rather than a permanent personal code. An actual offer may involve different duties, so the employer’s proposed role needs its own assessment.
Usually you need more context. Titles vary between organisations, and similar labels can describe different responsibilities. Obtain the job description and compare the core duties, working context and level of responsibility with the relevant classification information.
No. Occupational eligibility is only one part of the route. Sponsorship, salary, personal eligibility and other requirements still matter. Neither a coding-tool result nor a number displayed in an advert constitutes approval of an individual application.
The classification needs to reflect the actual work. A preferred salary outcome is not a sound reason to misdescribe the role. Discuss a suspected mismatch with the sponsor and use the appropriate review or advice process before proceeding.
It signals that additional checks are needed under the current framework. Examine the relevant shortage provisions, restrictions and any applicable transitional rules. Your circumstances and the exact job matter, so do not infer eligibility from the label alone.
No. Your educational background and the classification of the proposed job are different matters. A highly qualified person can apply for a role with different duties or responsibility. Research the position itself rather than treating the degree as the coding answer.
The classification framework and immigration provisions can change, and a new job may also have different responsibilities. Compare the old and current documents, relevant dates and actual duties. Ask the sponsor to explain the reason instead of assuming the change is automatically an error.
Ask the employer which provisions, table, hours calculation and evidence support its assessment. A valid exception may require specific conditions, while an unexplained shortfall needs resolution. Do not attempt to fix the issue by inventing duties or selecting an unrelated code.
30. Your Final Occupation-Code Checklist
Start with a clear description of the work, then obtain the employer’s proposed four-digit SOC 2020 code. Use official resources to compare the category with the role rather than relying only on a title or search snippet.
Check the eligibility label and investigate any additional conditions. Keep the applicable shortage-list wording, relevant dates and any transitional explanation with your notes. Then complete a separate salary check using the appropriate rate, working hours and provisions.
Confirm the employer and offer independently. Compare the information prepared for your application with the job you have actually accepted, and resolve inconsistencies before relying on it.
For broader preparation, explore Spreemkt’s Skilled Work Visa guide and relocation guide for applicants from Nigeria. A dependable occupation-code check gives you a clearer understanding of an offer. It should support informed decisions about real work, realistic pay and a lawful application process.
