    UK visa sponsorship allows British businesses to recruit qualified overseas nationals to fill genuine skills shortages by obtaining a Home Office sponsor licence and issuing Certificates of Sponsorship. To secure and maintain a licence, employers must prove they are a trading entity with robust human resources systems, appoint qualified key personnel, pay statutory salary thresholds, and comply with strict reporting and record-keeping duties. Non-compliance risks severe civil penalties, licence suspension, or complete revocation.

    The UK points-based immigration system governs how non-settled workers enter and remain in the UK labour market. Under the Immigration Act 1971 and the Immigration Rules (principally Appendix Skilled Worker, Appendix Global Business Mobility, and Appendix Sponsor Mortalities), any UK organisation wishing to employ a non-settled worker must hold a valid sponsor licence granted by UK Visas and Immigration (UKVI), an operating directorate of the Home Office.

    Sponsorship acts as a legal bridge between an employer and an overseas candidate. When UKVI grants a sponsor licence, it places significant trust in the employer. The sponsoring business acts as a gatekeeper to the UK immigration system, confirming that the role is genuine, the candidate possesses the required skills and English language proficiency, and the remuneration meets statutory minimums. In exchange for access to the international talent pool, the employer assumes rigorous, legally binding compliance duties.

    Main Sponsored Work Routes

    Businesses typically apply for a licence across one or more specific sub-tiers, depending on their commercial requirements:

    1. Skilled Worker Route: The primary long-term work visa for recruiting skilled professionals from outside the UK or switching eligible migrants already inside the country. It leads to settlement (Indefinite Leave to Remain) after five years of continuous lawful residence.
    2. Global Business Mobility (Senior or Specialist Worker): Designed for multinational companies transferring established, senior, or highly specialised staff from an overseas linked entity to a UK branch. This route does not lead directly to settlement.
    3. Scale-up Route: Tailored for high-growth UK businesses experiencing rapid employment or turnover expansion, offering a faster route with reduced ongoing sponsorship obligations after the initial six-month period.
    4. Temporary Work Routes: Covering specialised short-term categories such as Creative Workers, Charity Workers, and Government Authorised Exchange programmes.

    Failure to identify the correct route at the point of application leads to operational delays, wasted statutory fees, and the risk of outright refusal.

    Assessing Employer Eligibility: Can Your Business Apply for a Licence?

    Before preparing an application, an organisation must assess whether it satisfies the mandatory threshold requirements set out in the Home Office sponsor guidance.

    Eligibility Criteria for the Business Entity

    To qualify for a Worker or Temporary Worker sponsor licence, your business must demonstrate that:

    • It is a genuine organisation operating lawfully in the UK, supported by corporate registrations, tax documentation, and trading presence.
    • It has an operating address, physical trading premises, or a verifiable digital operating structure registered in the UK.
    • It has no unspent criminal convictions for immigration offences or certain other crimes such as fraud, money laundering, or modern slavery.
    • It has no history of persistent failure to meet immigration obligations or recent sponsor licence revocations within the statutory cooling-off period (usually 12 months).
    • It has the capacity to offer genuine vacancies that meet the relevant skill and salary thresholds.

    If the business is a newly formed start-up trading for less than 18 months, it must provide specific evidence establishing an active UK corporate bank account, VAT registration (if applicable), employer liability insurance, and proof of premises.

    Mandatory Key Personnel Roles

    Every licensed sponsor must appoint named individuals to manage the sponsorship process through the online Sponsorship Management System (SMS). These roles can be held by the same person or divided among different individuals, subject to strict Home Office rules:

    • Authorising Officer (AO): The most senior person in the organisation responsible for the recruitment of all overseas workers and the activities of all SMS users. The AO must ensure that all sponsorship duties are met. This individual bears ultimate legal responsibility for the licence.
    • Key Contact (KC): The main point of contact between UKVI and the business. Caseworkers contact the Key Contact to arrange compliance visits, request information, or discuss applications.
    • Level 1 User: The operational user who conducts day-to-day administration on the SMS, including assigning Certificates of Sponsorship, reporting employee changes, and applying for licence renewals. At least one Level 1 User must be a direct employee, partner, or director of the company at all times.
    • Level 2 User: An optional user role with restricted permissions, capable of assigning CoS and reporting certain worker changes, but unable to manage organisational licence details.

    Key Personnel Requirements and Decision Points

    All Key Personnel must be based in the UK, possess British citizenship, Irish citizenship, or valid settled or pre-settled status, or hold lawful immigration permission with no restrictions on work. A sponsored worker cannot act as the Authorising Officer, except in businesses employing fewer than five direct staff where the sponsored worker is also the sole corporate owner.

    If the proposed Authorising Officer fails criminal record or compliance background checks conducted by UKVI, the entire sponsor licence application will be refused automatically.

    Step-by-Step Guide: How to Apply for a UK Sponsor Licence

    Securing a sponsor licence requires a structured sequence of administrative and legal steps. Missing a single procedural requirement can trigger a refusal with no right of appeal.

    Step 1: Determine Licence Tier & Appoint Key Personnel
           │
    Step 2: Collate Minimum 4 Supporting Documents (Appendix A)
           │
    Step 3: Submit Online Application & Pay Fee
           │
    Step 4: Email Submission Sheet & Documents within 5 Working Days

    Step 5: UKVI Caseworker Review (Possible Pre-Licence Audit)
           │
    Step 6: Licence Granted (A-Rated) & SMS Access Issued
    

    Step 1: Selecting Licence Categories and Checking Roles

    Identify which visa routes your business needs immediately and over the next 12 to 24 months. Most employers apply for the Skilled Worker category, but multinational entities should consider adding the Global Business Mobility routes simultaneously to avoid paying separate licence variation fees later.

    Step 2: Gathering Mandatory Documentation (Appendix A)

    UKVI specifies strict evidentiary requirements in Appendix A of the sponsor guidance. Most standard commercial businesses must provide at least four specific documents from the approved lists to establish their corporate legitimacy and UK presence.

    Step 3: Submitting the Online Sponsor Application

    The organisation completes and submits the online application form via the GOV.UK portal, selecting the appropriate business size (small or medium/large) and paying the application fee.

    Step 4: Submitting the Appendix A Document Bundle

    Once the online form is submitted, the system generates an Application Submission Sheet. The Authorising Officer must sign and date this sheet. All supporting documents, along with the signed sheet, must be sent electronically to UKVI within five working days of the online submission date.

    If the evidence is not received within this five-day window, UKVI will reject the application, retain an administration charge, and require the organisation to begin the process again.

    Step 5: UKVI Caseworker Review and Compliance Audits

    UKVI evaluates the evidence against statutory databases, including Companies House, HMRC PAYE records, and the directorship disqualification register. Caseworkers may conduct a pre-licence compliance visit (either announced or unannounced) or an interactive digital audit to inspect the physical premises, review HR files, and interview key personnel.

    Step 6: Grant of Licence and SMS Activation

    Upon approval, UKVI issues an approval letter confirming the grant of an A-rated sponsor licence. The Level 1 User receives their user identifier and temporary credentials to access the Sponsorship Management System (SMS). Licences granted or renewed on or after 6 April 2024 do not expire after four years, removing the previous automatic four-year renewal requirement, though they remain subject to ongoing compliance and unannounced audits.

    Sponsorship Costs, Statutory Fees, and Levies

    Budgeting for international recruitment requires accounting for licence fees, individual sponsorship costs, and candidate visa charges. Costs vary significantly depending on whether the business qualifies as a small or medium/large sponsor under the Companies Act 2006.

    A business qualifies as a small sponsor if it meets at least two of the following conditions in a financial year:

    • Annual turnover of £10.2 million or less
    • Balance sheet total of £5.1 million or less
    • 50 employees or fewer

    Charities registered with the Charity Commission also qualify for small sponsor fee rates.

    Item / Fee CategorySmall Sponsor / CharityMedium or Large SponsorNotes / Frequency
    Sponsor Licence Application Fee£536£1,476Paid once at application (Skilled Worker)
    Licence Priority Processing Service£500£500Optional: reduces processing time to 10 working days
    Certificate of Sponsorship (CoS) Fee£239£239Per assigned Certificate (Skilled Worker)
    Immigration Skills Charge (ISC)£364 per year£1,000 per yearPaid upfront per year of sponsorship length
    Skilled Worker Visa Application Fee (up to 3 years)£719 to £1,084£719 to £1,084Paid by applicant or employer per person
    Skilled Worker Visa Application Fee (over 3 years)£1,420 to £2,164£1,420 to £2,164Paid by applicant or employer per person
    Immigration Health Surcharge (IHS)£1,035 per year£1,035 per yearPaid per year of visa per applicant/dependant

    The Immigration Skills Charge (ISC)

    The Immigration Skills Charge is a statutory levy imposed on employers sponsoring workers on the Skilled Worker and Global Business Mobility routes. The fee must be paid in full upfront when the Certificate of Sponsorship is assigned.

    • Small sponsors pay £364 for the first 12 months, plus £182 for each additional six-month period.
    • Medium and large sponsors pay £1,000 for the first 12 months, plus £500 for each additional six-month period.

    ISC Exemptions

    Employers do not pay the Immigration Skills Charge if:

    • The worker is sponsored under specific SOC codes (such as chemical scientists, biological scientists, higher education teaching professionals, or clergy).
    • The worker is switching from a Student visa into a Skilled Worker visa inside the UK.
    • The CoS is assigned for a period of less than six months under specific sub-tiers.

    If the sponsorship ends earlier than planned (for example, if the worker resigns within the first year), UKVI issues a partial, pro-rata refund for each full unspent six-month period of sponsorship.

    Fee Clawback Rules under UK Employment Law

    Employers often invest substantial sums when sponsoring an international candidate. However, businesses must strictly observe immigration rules and UK employment law regarding fee recovery:

    • Prohibited Clawbacks: An employer cannot, under any circumstances, recover the sponsor licence application fee, CoS assignment fee, or Immigration Skills Charge from the worker. Passing these costs to the employee violates sponsor duties and will lead to licence revocation.
    • Permissible Clawbacks: An employer may agree to fund the employee's visa application fee, legal representation costs, relocation allowances, or Immigration Health Surcharge, and make these recoverable on a sliding scale via a formal Clawback Agreement if the employee leaves within a specified period (such as 12 to 24 months).

    Certificates of Sponsorship (CoS): Defined vs Undefined

    A Certificate of Sponsorship is not a paper certificate; it is a virtual record generated on the SMS. Every worker you sponsor must have an active, assigned CoS reference number before submitting their visa application.

                    Candidate Location / Status
                                 │

    Defined Certificates of Sponsorship

    Defined CoS are required exclusively for candidates applying for a Skilled Worker visa from outside the UK. Sponsors cannot hold a pool of Defined Certificates in advance.

    1. Application Process: The sponsor submits an individual request through the SMS for each specific candidate, detailing the job title, SOC 2020 code, detailed job duties, working hours, and gross salary.
    2. Assessment: UKVI reviews the request to verify that the proposed salary meets or exceeds the occupation going rate and the general threshold, and checks whether the role is a genuine vacancy.
    3. Turnaround Time: Standard requests are processed within one to two working days, provided caseworkers do not require additional evidence regarding the vacancy.

    Undefined Certificates of Sponsorship

    Undefined CoS are used for:

    • Candidates already lawfully in the UK under another eligible immigration category (such as a Graduate or Student visa) switching to the Skilled Worker route.
    • Existing sponsored employees applying for an extension of stay or a change of employment with the same sponsor.
    • All workers sponsored under the Global Business Mobility or Scale-up routes, regardless of location.

    Sponsors request an annual allocation of Undefined Certificates during their licence application or via an annual request on the SMS (running on a cycle from 6 April to 5 April each year). If your pool runs out, you must submit an in-year allocation increase request via the SMS, which takes up to 18 weeks unless accelerated through the paid priority service.

    Skilled Worker Route: Skill Level, SOC Codes, and Salary Rules

    To sponsor a worker under the Skilled Worker route, the role must meet mandatory skill and salary criteria.

    Skill Level and the SOC 2020 System

    The sponsored occupation must be skilled to at least RQF Level 3 (equivalent to UK A-levels or Scottish Highers). The candidate does not need to hold a formal degree, but the job itself must meet this skill threshold. Employers must map the job duties to the Standard Occupational Classification (SOC) system, currently based on the SOC 2020 system.

    Caseworkers compare your internal job title and duties against the Office for National Statistics (ONS) occupation coding tool to confirm that you have chosen the appropriate SOC code.

    Minimum Salary Thresholds

    Under rules introduced on 4 April 2024, the general standard salary threshold for a Skilled Worker is the higher of:

    • £38,700 gross per annum, or
    • The 50th percentile (median) going rate for the specific SOC 2020 occupation code.

    Salaries must also comply with UK National Minimum Wage legislation and be calculated on the worker's contracted hours (based on a standard 37.5-hour working week for going-rate comparisons).

    Tradable Points and Salary Discounts

    Candidates who do not meet the full £38,700 or median going rate may still qualify if they are eligible for salary discounts under tradable points options, subject to an absolute floor of £30,960 per annum:

    • New Entrants: Individuals under 26 years old, those switching from Student or Graduate visas, or individuals working towards recognised professional qualifications can be paid 70% of the occupation going rate, provided the salary is at least £30,960 per year. Sponsoring an employee as a New Entrant is limited to a cumulative maximum of four years across all periods of leave under the route.
    • Relevant PhD Qualifications: A candidate holding a relevant STEM PhD can be paid 80% of the going rate (minimum £30,960). A candidate with a non-STEM relevant PhD can be paid 90% of the going rate (minimum £34,830).
    • Immigration Salary List (ISL): Roles on the Immigration Salary List (which replaced the Shortage Occupation List) carry a general threshold reduction to £30,960, but employers must still pay 100% of the specific occupation going rate.

    English Language and Financial Maintenance

    Candidates must prove English language ability to at least Level B1 on the Common European Framework of Reference for Languages (CEFR) in reading, writing, speaking, and listening. This can be satisfied through nationality of an English-speaking country, an approved UK degree or Ecctis-certified equivalent, or passing a Secure English Language Test (SELT).

    Candidates must also demonstrate financial maintenance of at least £1,270 in personal savings held for 28 consecutive days, unless the A-rated sponsor certifies maintenance on the Certificate of Sponsorship, agreeing to support the worker if necessary during their first month.

    Required Evidence and Documents: What Caseworkers Look For

    UKVI evaluates sponsor licence applications and compliance records against published evidentiary standards in Appendix A and Appendix D.

    Appendix A Mandatory Business Documents

    Employers must submit at least four documents chosen from the prescribed tables in Appendix A. Common acceptable document bundles include:

    1. Proof of Corporate Bank Account: A business bank statement from an FCA/PRA-regulated UK financial institution, issued within the last month, showing active trading transactions.
    2. HMRC Documentation: Evidence of registration for PAYE and National Insurance, accompanied by recent HMRC payment submissions (such as an RTI report or P303).
    3. Proof of VAT Registration: A copy of the VAT registration certificate issued by HMRC.
    4. Proof of Trading Premises: A formal commercial lease, freehold title deed, or commercial licence agreement confirming the right to occupy business premises in the UK.
    5. Audited Financial Statements: Full annual accounts certified by an independent, qualified chartered accountant (mandatory for medium/large entities).
    6. Regulatory Registration: Where the sector requires professional oversight (such as the Care Quality Commission, Financial Conduct Authority, or Solicitors Regulation Authority), proof of active, unrestricted registration.

    Appendix D Record-Keeping Checklist for Sponsored Workers

    Under Appendix D, sponsors must create and maintain a compliant personnel file for every sponsored worker throughout their employment and retain it for at least one year after sponsorship ends:

    • Copy of Right to Work Verification: A dated PDF copy of the Home Office online right to work check confirmation.
    • Contract of Employment: Signed contract outlining job duties, working hours, place of work, and agreed salary matching the CoS.
    • Salary and Payroll Records: Historical payslips and corresponding bank transfer records proving actual payments made via PAYE.
    • Recruitment History: A summary of how the worker was identified (advertisements, interview notes, or recruitment agency agreements), demonstrating that a genuine vacancy existed.
    • Professional Registrations and Qualifications: Copies of degrees, certifications, or regulatory licences required to perform the role.
    • Current Contact Details: Comprehensive contact records, including residential address, personal email, landline, and mobile telephone numbers, with a history of any changes.
    • Absence and Attendance Records: Accurate records of all statutory leave, sick leave, annual leave, and authorised business absences.

    What Caseworkers Look For During an Audit

    When reviewing an application or auditing a premises, UKVI caseworkers focus on three core areas:

    • HR Systems Capacity: Can the business track employee visa expiry dates, manage absence reporting, and identify non-attendance within statutory reporting windows?
    • Genuine Vacancy Assessment: Does the role realistically fit within the company's trading model, or was the role fabricated to facilitate the entry of an overseas national?
    • Key Personnel Integrity: Are the named users genuine senior employees capable of discharging legal duties without undue influence from external parties?

    Sponsorship Management System (SMS) Operations and Employer Duties

    Holding a sponsor licence requires proactive management of the SMS. Compliance duties fall into two main categories: reporting duties and record-keeping duties.

    Mandatory 10-Day Worker Reports

    A Level 1 User must submit a report via the SMS within 10 working days of any of the following events involving a sponsored worker:

    • Delayed Start Date: The worker fails to start work within 28 days of the start date listed on their CoS or the visa validity start date.
    • Unauthorised Absence: The worker is absent from employment for more than 10 consecutive working days without permission.
    • Early Termination: The worker resigns, is dismissed, or is made redundant before the CoS expiry date.
    • Salary Reductions: Any reduction in the worker's salary, provided it remains above the statutory threshold (significant cuts below thresholds require cancellation of sponsorship).
    • Role Changes within the Same SOC Code: Significant alterations to job duties or title where the SOC code remains unchanged.
    • Change of Work Location: Changes to the primary office address, addition of client sites, or formal transitions to permanent hybrid/remote working arrangements.

    Mandatory 20-Day Corporate Reports

    The sponsor must notify UKVI within 20 working days of structural changes affecting the business:

    • Change of legal entity name, trading name, or registered office address.
    • Appointment or departure of the Authorising Officer, Key Contact, or Level 1 User.
    • Sale of business assets, corporate restructuring, merger, takeover, or demerger.
    • Entering into administration, liquidation, company voluntary arrangement, or ceasing to trade.

    Failure to submit corporate notifications within the 20-day timeframe is one of the most common reasons for immediate licence suspension.

    Right to Work Checks and the Civil Penalty Regime

    All UK employers must conduct statutory right to work checks before an employee begins employment. For biometric residence permit holders, eVisa holders, and status holders under the EU Settlement Scheme, right to work verification must be performed digitally using the Home Office online right to work checking service with the candidate's date of birth and share code.

    Physical document checks are only valid for British and Irish citizens (using original passports) or individuals with specific non-digital status.

    Civil Penalties for Illegal Working

    Under legislation effective from February 2024, the civil penalty for employing an illegal worker without establishing a statutory excuse is:

    • Up to £45,000 per illegal worker for a first breach.
    • Up to £60,000 per illegal worker for repeat breaches within a three-year period.

    In addition to financial penalties, illegal working findings trigger immediate revocation of the sponsor licence, public naming of the business, and potential criminal prosecution under Section 21 of the Immigration, Asylum and Nationality Act 2006.

    Common Mistakes, Refusal Triggers, and Licence Downgrades

    Many sponsor licence applications fail or licences are subsequently revoked due to preventable administrative and procedural errors.

                            No new CoS allowed)    Worker visas curtailed)
    

    1. Inappropriate SOC Code Allocation

    Selecting a SOC code that artificially inflates the skill level of a low-skilled role (known as role stretching) is a major trigger for refusal. If UKVI determines that an administrative assistant was classified as a Business and Management Consultant to meet the RQF Level 3 threshold, the application will be refused under the Genuine Vacancy test.

    2. Missing the Five-Day Document Submission Window

    When applying for a licence, failing to submit all Appendix A supporting documents by email within five working days of the online application leads to immediate rejection and administrative forfeiture.

    3. Appointing Unqualified Key Personnel

    Naming an external third-party consultant (who is not a regulated immigration adviser registered with the OISC or Law Society) as the Authorising Officer or Level 1 User will cause an immediate licence refusal. Key personnel must be genuine employees or directors, unless specific third-party representative exemptions apply.

    4. Failing to Record Work Locations (Hybrid Working)

    Following widespread adoption of hybrid and remote working models, many sponsors fail to notify UKVI when a worker works from home several days a week or relocates to a different residential region. Caseworkers visiting the registered office who find the sponsored worker working remotely without an SMS report on file can treat this as a breach of monitoring duties.

    5. Licence Sanctions: B-Rating, Suspension, and Revocation

    If UKVI identifies compliance failures during a site visit, it can impose severe administrative penalties:

    • Downgrading to a B-Rating: For minor administrative failures, UKVI downgrades the sponsor to a B-rating. The business is placed on a formal Action Plan (costing a statutory fee of £1,476) that must be satisfied within three months. While B-rated, the sponsor cannot issue new Certificates of Sponsorship to recruit new talent.
    • Licence Suspension: For serious breaches (such as unrecorded salary reductions or missing right to work records), UKVI issues a suspension notice giving the employer 20 working days to submit written representations.
    • Licence Revocation: If representations fail or severe illegal working is discovered, UKVI revokes the licence. The sponsor cannot apply for a new licence for at least 12 months (or longer if civil penalties remain unpaid). All existing sponsored workers have their visas curtailed to 60 days, forcing them to find a new sponsor or leave the UK.

    Edge Cases and Complex Sponsorship Scenarios

    Navigating real-world immigration cases requires understanding how specific transitional protections, corporate events, and visa rules apply to individual circumstances.

    Sponsoring Dependants: Current Rules and Restrictions

    Under immigration changes introduced in early 2024, significant restrictions apply to dependants of sponsored workers:

    • Skilled Workers: Sponsoring a worker under standard Skilled Worker SOC codes allows the worker to bring their partner (spouse or civil partner) and dependent children under 18. However, care workers and senior care workers under SOC codes 6135 and 6136 are completely barred from bringing dependants to the UK.
    • Maintenance Requirements: The main applicant or sponsor must demonstrate additional financial funds for each dependant (£285 for a partner, £315 for the first child, and £200 for each additional child) unless maintenance is certified on the CoS.

    In-Country Switching and Restrictions on Students

    Individuals in the UK on eligible visas can switch into the Skilled Worker route without leaving the country. However, strict restrictions apply to students:

    • Student Visa Holders: A student cannot switch into the Skilled Worker route unless they have completed their course of study, or the job start date on their CoS is after the official course completion date. For PhD students, they must have completed at least 24 months of study toward their doctorate before they are permitted to switch.
    • Graduate Visa Holders: Graduates can switch into the Skilled Worker route at any time before their visa expires and are eligible for the New Entrant salary rate.
    • Ineligible Categories: Visitors, short-term students, seasonal workers, and domestic workers in private households cannot switch into the Skilled Worker route inside the UK; they must depart the country and submit an entry clearance application.

    Continuous Residence and ILR Absences

    Sponsored workers aiming for settlement (Indefinite Leave to Remain) after five years must satisfy continuous residence rules:

    • The worker must not have spent more than 180 days outside the UK in any rolling 12-month period during the qualifying five-year period.
    • Absences for work purposes, annual leave, or serious illness count toward the 180-day limit. Sponsors must keep accurate records of work-related international travel to provide supporting employer letters when the worker applies for ILR.

    Transitional Salary Protections (Pre-4 April 2024 Cohort)

    Workers who held valid permission as a Skilled Worker before 4 April 2024 benefit from transitional protections when extending their stay or changing sponsors before 1 December 2030:

    • Their general salary threshold is calculated against a lower baseline (typically £29,000 per annum instead of £38,700).
    • Their occupation going rate is pegged to the 25th percentile of the previous SOC 2010 going rates, updated to reflect current economic baselines, rather than the standard 50th percentile median.

    Employers taking over sponsorship of an existing migrant worker should carefully assess whether the candidate qualifies for these lower transitional thresholds.

    Corporate Restructuring, Mergers, and TUPE Transfers

    When a corporate restructuring, acquisition, or merger occurs, sponsorship obligations transfer under the Transfer of Undertakings (Protection of Employment) Regulations 2006 (TUPE):

    • If a business with a sponsor licence acquires sponsored employees via a TUPE transfer, the receiving entity must report the transfer on its SMS within 20 working days.
    • If the receiving entity does not hold a sponsor licence, it must submit an application for a sponsor licence within 20 working days of the transfer date to protect the lawful immigration status of the transferring employees.
    • Failure to act within this 20-day window results in the automatic curtailment of all transferred workers' visas.

    Supplementary Employment and Secondary Sponsorship

    Sponsored workers on the Skilled Worker route are permitted to undertake supplementary employment without notifying UKVI, provided that:

    • The supplementary work is in an occupation code listed on the Immigration Salary List or in the same profession and professional level as the job on their Certificate of Sponsorship.
    • The supplementary employment does not exceed 20 hours per week.
    • The work takes place outside the normal working hours contracted by their primary sponsor.

    If the secondary role does not meet these criteria, the secondary employer must obtain its own sponsor licence and issue a separate, secondary Certificate of Sponsorship.

    Practical Next Steps for Employers

    Before initiating an application for a UK sponsor licence or assigning a Certificate of Sponsorship, businesses should take immediate operational measures to ensure compliance readiness:

    1. Conduct an Internal HR and Document Audit: Review all right to work records across the existing workforce to ensure no historic civil penalty vulnerabilities exist, and check that personnel files contain the mandatory evidence items specified under Appendix D.
    2. Formalise Job Descriptions and Match SOC Codes: Map all target international roles against the ONS SOC 2020 occupation coding tool, verifying that proposed remuneration meets the higher of the £38,700 baseline or the occupation median going rate.
    3. Identify and Vet Key Personnel: Formally designate the Authorising Officer, Key Contact, and Level 1 User, confirming that each individual meets the residence, background, and settled status requirements.
    4. Assemble the Appendix A Evidentiary Bundle: Collate at least four qualifying corporate documents from UKVI's prescribed tables (including up-to-date business bank statements, VAT certificates, and premises leases) before submitting the online application form to satisfy the strict five-working-day submission deadline.
