Navigating the Changing Landscape: EU Citizens and the UK Labour Market Post-Brexit

Since the end of European Union free movement on 31 December 2020, EU, EEA, and Swiss citizens require valid UK immigration permission to work, live, or study in the United Kingdom. For those residing in the UK prior to that date, lawful status is maintained through the EU Settlement Scheme, whereas all prospective arrivals must secure sponsorship or a valid visa under the points-based immigration system. Employers and EU nationals must now navigate formal right to work compliance, sponsor licence duties, specific salary thresholds, and strict continuous residence rules to ensure ongoing immigration legality.

The Legal Framework Governing EU Citizens Post-Brexit

The Immigration and Social Security Co-ordination (EU Withdrawal) Act 2020 brought an end to free movement rights across the United Kingdom on 31 December 2020 at 23:00 GMT. From that moment, the legal status of European Union (EU), European Economic Area (EEA), and Swiss citizens was decoupled from European Union law and brought entirely under domestic UK immigration legislation.

Today, the UK immigration system categorises EU citizens into two distinct legal groups:

1. Pre-2021 Arrivals and Qualifying Family Members: Individuals who established lawful continuous residence in the UK before 23:00 GMT on 31 December 2020, and who derive their right to work and reside from Appendix EU of the Immigration Rules under the EU Settlement Scheme (EUSS).
2. Post-2020 Arrivals: Individuals who entered the UK on or after 1 January 2021, who are subject to the same points-based immigration controls as non-EU nationals, requiring formal entry clearance or permission to stay under specific routes such as the Skilled Worker route, Global Business Mobility, or Student visa.

An important statutory exception applies to Irish citizens. Under the long-standing Common Travel Area (CTA) arrangements, Irish citizens retain the automatic right to enter, live, and work in the United Kingdom without requiring permission under the points-based system or the EU Settlement Scheme, except where they are subject to a deportation order or exclusion decision.

For all other European nationals, the absence of valid immigration status renders employment unlawful under Section 15 of the Immigration, Asylum and Nationality Act 2006, exposing employers to severe civil penalties and individuals to enforcement action.

Pathway 1: The EU Settlement Scheme (Pre-2021 Arrivals)

Appendix EU of the Immigration Rules provides the basis for EU, EEA, and Swiss citizens who resided in the UK before the end of the transition period to regularise their stay. Although the standard deadline for applications was 30 June 2021, the scheme continues to process late applications, status transitions, and applications for joining family members.

Settled Status versus Pre-Settled Status

The scheme grants two forms of immigration permission depending on the duration of residence established in the UK:

• Settled Status (Indefinite Leave to Enter or Remain): Granted to applicants who have completed a continuous qualifying period of at least five years of UK residence. Settled status confers permanent residency without an expiry date, though it can be lost through an absence from the UK of more than five consecutive years (or four consecutive years for Swiss citizens).
• Pre-Settled Status (Limited Leave to Enter or Remain): Granted to applicants who arrived before 31 December 2020 but had completed less than five years of continuous qualifying residence. Pre-settled status is temporary permission that allows the holder to accrue the necessary five years to qualify for settled status.

Automatic Extensions and the High Court Judgment

Following the December 2022 High Court judgment in Independent Monitoring Authority v Secretary of State for the Home Department, the Home Office amended its operational guidance regarding pre-settled status holders. The court established that individuals do not lose their right of residence simply because they failed to make a second application under Appendix EU before their pre-settled status expired.

In response, the Home Office introduced automated extensions. Pre-settled status is now automatically extended by two years before its scheduled expiry date on the Home Office database. Furthermore, the Home Office has begun implementing automated checks against HM Revenue and Customs (HMRC) and Department for Work and Pensions (DWP) data to switch qualifying pre-settled status holders to settled status without requiring a manual application.

However, relying on automated systems carries risks if an individual's tax or national insurance records do not clearly reflect five years of unbroken residence. Where gaps exist in government records, the individual must submit a formal application for settled status with supplementary documentary evidence to avoid discrepancies during employment or right to work checks.

Late Applications and Reasonable Grounds

Under Home Office guidance updated in August 2023, the threshold for submitting a late application to the EU Settlement Scheme is strictly enforced. Caseworkers must first assess whether an applicant has established reasonable grounds for the delay before assessing whether the substantive residence requirements of Appendix EU are met.

Where an applicant cannot satisfy the caseworker that reasonable grounds prevented them from applying before 30 June 2021, the application is rejected as invalid without substantive consideration of the underlying residence evidence. Valid reasonable grounds may include:

• Children whose parents failed to apply on their behalf while they were minors.
• Individuals with physical or mental capacity impairments during the application window.
• Victims of modern slavery or domestic abuse.
• Severe, debilitating medical conditions that prevented timely action.

General lack of awareness of the scheme, minor administrative oversights, or misunderstandings regarding the requirement to apply do not constitute valid reasonable grounds.

Joining Family Members

Family members of EU, EEA, or Swiss citizens with settled or pre-settled status can apply to join their sponsor in the UK under Appendix EU (Family Permit) and Appendix EU. The qualifying relationship must have existed prior to 31 December 2020 (except in the case of children born or adopted after that date) and must continue to exist at the date of application. Eligible relationships comprise spouses, civil partners, durable partners (with proof of two years cohabitation prior to 31 December 2020 or an EU document issued before that date), dependent children, and dependent parents.

Pathway 2: The Points-Based System and the Skilled Worker Route

EU nationals who arrived in the UK on or after 1 January 2021, or who do not qualify under Appendix EU, must obtain a visa under the points-based immigration system to work lawfully. The primary route for direct employment is the Skilled Worker visa under Appendix Skilled Worker.

The Points Breakdown

To secure a Skilled Worker visa, an applicant must score a total of 70 points. Fifty points are mandatory and non-tradable, while the remaining 20 points must be earned through salary or other compensatory attributes:

1. Mandatory Sponsorship (20 points): The applicant must hold a valid Certificate of Sponsorship (CoS) assigned by a Home Office-licensed sponsor.
2. Job at Appropriate Skill Level (20 points): The role must be categorised under an eligible Standard Occupational Classification (SOC) 2020 code at Regulated Qualifications Framework (RQF) Level 3 or higher (equivalent to UK A-levels).
3. English Language Proficiency (10 points): The applicant must demonstrate English language competence to at least CEFR Level B1 in reading, writing, speaking, and listening. This can be satisfied via an approved Secure English Language Test (SELT), a degree taught in English verified by Ecctis, or by holding citizenship of a majority English-speaking country.
4. Salary and Tradable Points (20 points): The applicant must be paid a salary that meets or exceeds both the general threshold and the specific occupation going rate.

Salary Thresholds and Standard Occupational Classification (SOC) 2020

On 4 April 2024, the Home Office introduced major revisions to salary requirements, transitioning to the SOC 2020 coding system and raising baseline thresholds. For applications submitted using a Certificate of Sponsorship assigned on or after 4 April 2024, the baseline salary rules are as follows:

• Standard General Threshold: £38,700 per year, or the specific occupational code going rate (based on the 50th percentile of full-time earnings in the UK), whichever is higher.
• Transitional General Threshold: £29,000 per year, or the specific occupational code going rate (based on the 25th percentile of full-time earnings), whichever is higher. This applies exclusively to individuals who were continuously sponsored on the Skilled Worker route before 4 April 2024 and are extending their stay, changing employment, or applying for settlement.
• Hourly Rate Floor: All salaries must meet or exceed £15.88 per hour (£11.90 per hour under transitional rules), regardless of total annual compensation.

Tradable Points Options

Where an applicant's salary falls below the standard £38,700 threshold (or below the full occupation going rate), they may trade specific attributes to obtain the final 20 points, provided the salary does not fall below the absolute statutory minimums:

• Option B (PhD in a relevant subject): Salary must equal at least £34,830 per year, £15.88 per hour, and 90% of the occupation going rate.
• Option C (PhD in a STEM subject): Salary must equal at least £30,960 per year, £15.88 per hour, and 80% of the occupation going rate.
• Option D (Immigration Salary List role): Salary must equal at least £30,960 per year, £15.88 per hour, and the going rate.
• Option E (New Entrants): Salary must equal at least £30,960 per year, £15.88 per hour, and 70% of the occupation going rate. An individual qualifies as a new entrant if they are under 26 years of age at the date of application, switching from a Student or Graduate visa, or working towards recognised professional qualifications (such as chartered accountant or solicitor status). The new entrant concession is capped at a maximum cumulative duration of three years across all visa routes.

Comparison of Work Routes for EU Nationals and UK Employers

The table below outlines the legal and operational differences across the primary immigration pathways available to EU citizens working in the UK.

Sponsor Licence Requirements for Employers Recruiting EU Nationals

UK employers seeking to hire EU nationals who do not hold status under the EU Settlement Scheme, Frontier Worker permits, or other non-sponsored permissions must hold a valid sponsor licence issued by UK Visas and Immigration (UKVI).

Sponsor Licence Application Criteria

To obtain a licence, an organisation must demonstrate that it is a genuine organisation operating lawfully in the UK, that it has suitable human resources and recruitment systems in place to manage sponsorship duties, and that the roles it intends to fill meet the requisite skill and salary levels.

An employer must designate key personnel on the application:

• Authorising Officer: A senior, competent person responsible for the actions of staff and representatives using the Sponsorship Management System (SMS) and ensuring compliance with all sponsor duties.
• Key Contact: The main point of contact between UKVI and the business.
• Level 1 User: The individual responsible for day-to-day management of the licence via the SMS, including assigning Certificates of Sponsorship and reporting migrant activity.

All key personnel must be paid employees or office holders of the business (with narrow exceptions for third-party legal representatives acting as Level 1 Users) and must pass UKVI background checks regarding criminal convictions and previous immigration compliance.

Mandatory Evidentiary Submissions

Under Appendix A of the sponsor guidance, most private sector businesses must supply at least four mandatory supporting documents to validate their trading presence and operational integrity. Standard submissions include:

1. Proof of active corporate bank account with an FCA-regulated bank.
2. Employer's liability insurance certificate providing cover of at least £5 million.
3. Proof of registration with HM Revenue and Customs for PAYE and National Insurance, accompanied by recent HMRC submission filings.
4. Proof of ownership or lease of business premises.
5. Audited annual accounts or a certified corporate tax return (CT600).

Failure to provide four compliant documents within five working days of a UKVI request results in the immediate refusal of the application and the forfeiture of the application fee.

Statutory Fees and Financial Levies

Sponsoring EU workers involves several government fees and levies, structured around the size of the sponsoring organisation as defined by the Companies Act 2006:

• Sponsor Licence Application Fee: £536 for small or charitable sponsors; £1,476 for medium or large sponsors.
• Certificate of Sponsorship (CoS) Fee: £239 per certificate assigned.
• Immigration Skills Charge (ISC): £364 per year of sponsorship for small or charitable sponsors; £1,000 per year of sponsorship for medium or large sponsors. For a five-year visa, a large sponsor must pay an upfront ISC of £5,000 at the time the CoS is assigned.
• Immigration Health Surcharge (IHS): Paid by the applicant (or reimbursed by the employer) at the statutory rate of £1,035 per year of permission (£776 per year for applicants under 18).

Mandatory Right to Work Checks and Employer Compliance

Since 1 July 2021, employers can no longer accept EU, EEA, or Swiss passports or national identity cards as proof of the right to work in the UK. Conducting an invalid right to work check removes an employer's statutory excuse against illegal employment civil penalties.

Digital Right to Work Verification Procedure

Most EU citizens hold digital immigration status (eVisa) through an online UKVI account. Employers must follow this three-step statutory process before employment commences:

1. Obtain a Share Code: The prospective employee generates a right to work share code (starting with the letter 'W') via the online GOV.UK portal.
2. Perform the Online Check: The employer accesses the official "View a job applicant's right to work details" portal, enters the share code along with the candidate's date of birth, and inspects the live digital record.
3. Confirm Identity and Retain Evidence: The employer must verify that the photograph displayed on the digital profile matches the candidate in person or via a live video call. The employer must download and retain a secure, unalterable electronic or printed copy of the profile screen displaying the date of the check, and store it for the entire duration of employment plus two years after the employment ends.

Handling Outstanding Applications (The Employer Checking Service)

If an EU national has a pending in-time application with the Home Office (such as an outstanding EUSS application or an in-country visa variation) and cannot provide a share code showing active status, the employer must submit an enquiry via the online Employer Checking Service (ECS).

Employment must not begin until the employer receives a Positive Verification Notice (PVN) from UKVI. A PVN provides a statutory excuse against a civil penalty for a maximum duration of six months from the date issued. The employer must diary a follow-up check prior to the six-month expiration date.

Increased Civil Penalties

Penalties for illegal employment are set at substantial statutory rates:

• First Breach: Up to £45,000 per illegal worker.
• Repeat Breaches (within three years): Up to £60,000 per illegal worker.

In addition to financial penalties, a failure of right to work compliance can trigger the immediate suspension or revocation of an employer's sponsor licence, the curtailment of all currently sponsored visas, and disqualification of company directors under the Company Directors Disqualification Act 1986.

Step-by-Step Application Process: From Job Offer to Visa Issuance

When hiring an EU citizen via the points-based system, employers and applicants must complete the following sequential steps:

Step 1: Role Evaluation and SOC Code Allocation

The employer must assess the duties of the vacancy against the SOC 2020 occupational code directory. The employer must match the genuine everyday tasks of the role to an eligible code, determine whether the role qualifies for the standard £38,700 threshold or an alternative tradable route, and confirm that the proposed salary meets the 37.5-hour standard full-time going rate.

Step 2: Requesting and Assigning the Certificate of Sponsorship

• Defined CoS: If the EU candidate is applying from outside the UK, the employer must submit an individual application for a Defined CoS via the SMS. UKVI reviews each application to verify genuine vacancy requirements, salary levels, and occupational coding. Decisions typically issue within one to two working days, though requests can face delays if UKVI requires additional clarification.
• Undefined CoS: If the EU candidate is already inside the UK with permission to switch immigration categories (for example, switching from a Student or Graduate visa), the employer assigns an Undefined CoS from its annual allocation.

Step 3: Online Visa Application Submission

Once the CoS is assigned, the applicant must complete the online visa application via GOV.UK within three months of assignment, and no more than three months before the employment start date stated on the CoS. The applicant pays the relevant visa application fee and the Immigration Health Surcharge.

Step 4: Identity Verification via the Smartphone App

EU, EEA, and Swiss citizens holding a biometric chip passport generally verify their identity using the "UK Immigration: ID Check" app on iOS or Android. This eliminates the need to attend a physical Visa Application Centre (VAC) or surrender physical passports. The app scans the biometric passport chip and captures a digital facial scan. If the app cannot read the passport chip, the applicant must book an appointment at a commercial VAC to enrol their facial photograph and fingerprints.

Step 5: Caseworker Assessment

UKVI assesses the application against Appendix Skilled Worker. Standard processing times are three weeks for applications submitted outside the UK and eight weeks for applications submitted inside the UK. Priority (5 working days) and Super Priority (next working day) processing services are available for an additional fee, subject to capacity.

Step 6: Grant of Leave and Onboarding

Upon approval, the EU citizen receives an approval email containing details of their eVisa status. No physical visa vignette or Biometric Residence Permit (BRP) card is issued to an EU national who applied via the smartphone app. The employee accesses their UKVI account, generates a right to work share code, and provides it to the employer to complete the pre-employment check.

Evidentiary Requirements and Caseworker Scrutiny

Home Office caseworkers apply strict assessment standards to Skilled Worker applications. Applications are assessed against mandatory rules and the genuine vacancy test.

What Caseworkers Inspect

1. Genuine Vacancy Assessment: Under Paragraph SW 5.5 of Appendix Skilled Worker, caseworkers evaluate whether the role genuinely exists, whether the tasks align with the assigned SOC code, and whether the job has been created primarily to facilitate the applicant's entry to the UK. Discrepancies between the applicant's prior employment history and the technical complexity of the sponsored role can trigger a genuine vacancy audit.

2. Salary Calculation Compliance: Caseworkers examine the contracted working hours. If the contract specifies more than 37.5 hours per week, the caseworker recalculates the going rate pro-rata. For example, if a SOC code has a published going rate of £40,000 per year based on a 37.5-hour week, but the applicant is contracted to work 40 hours per week, the actual required minimum salary is:

   $$\frac{£40,000}{37.5} \times 40 = £42,666.67$$

   If the employer states a salary of £40,000 for a 40-hour contract, the application will be refused for failing to meet the going rate.

3. Qualification and Skill Verification: Where tradable points for a PhD are claimed, caseworkers cross-reference the Ecctis reference number or check whether the applicant's institution satisfies UK degree comparability. Where professional registration is required by law (such as GMC registration for doctors or NMC registration for nurses), the caseworker verifies the applicant's current standing on the professional register.

4. Maintenance and Financial Evidence: Unless the employer has certified maintenance on the Certificate of Sponsorship (available only to A-rated sponsors), the applicant must submit personal bank statements showing held funds of at least £1,270 for a consecutive 28-day period ending no more than 31 days before the date of application.

Common Mistakes and Refusal Triggers

Errors in post-Brexit applications frequently lead to refusals, wasted fees, and compliance enforcement. Key pitfalls include:

• Assigning an Undefined CoS Instead of a Defined CoS: Applying for an overseas candidate using an in-country Undefined CoS is a mandatory ground for visa refusal. The application will be rejected, the visa fee lost, and the sponsor may face an investigation for improper SMS allocations.
• Selecting Incorrect SOC Codes: Choosing a SOC code with an artificially high skill level or lower salary requirement that does not accurately match the core day-to-day duties is viewed by UKVI as deception or an ungenuine vacancy. Caseworkers inspect job descriptions and can interview both the applicant and the Authorising Officer.
• Misapplying New Entrant Salary Discounts: Attempting to claim new entrant points when the applicant has already held three cumulative years of permission under the Graduate, Tier 2, or Skilled Worker routes results in refusal, as the 20 tradable points cannot be awarded.
• Failing the Reasonable Grounds Test for Late EUSS Applications: Submitting an Appendix EU application after the 30 June 2021 deadline without comprehensive documentary evidence explaining the precise reasons for the delay leads to immediate rejection without review of residence history.
• Allowing Sponsored Staff to Work at Unlisted Third-Party Sites: Sponsoring a worker who is effectively hired out to a third party to undertake routine ongoing work (rather than delivering a defined contract of services) breaches sponsor rules and leads to licence revocation.
• Overlooking EUSS Pre-Settled Absence Limits: Assuming that holding pre-settled status protects an individual from losing their eligibility for settled status. Absences exceeding six months in any twelve-month period break continuous residence, permanently preventing the transition to settled status unless qualifying under strict exceptional provisions.

Critical Edge Cases in Post-Brexit UK Immigration

Dependants and Family Members

Under Appendix Skilled Worker, sponsored EU nationals can bring dependent partners (spouses, civil partners, or unmarried partners with two years of cohabitation) and children under the age of 18 at the date of application. Key rules governing dependants include:

• Maintenance Funds: Dependant applications require proof of funds unless the sponsor certifies maintenance. The required amounts are £285 for a partner, £315 for the first child, and £200 for each subsequent child, held continuously for 28 days.
• Care Worker Dependant Restrictions: Effective 11 March 2024, Skilled Workers sponsored under SOC codes 6135 (Care workers and home carers) and 6136 (Senior care workers) are prohibited from bringing dependants to the UK, unless they were already sponsored under those codes prior to that date and have held continuous permission on the route.
• Work and Study Rights: Dependants on the Skilled Worker route hold unrestricted rights to work in the UK (except as a professional sportsperson) and can engage in study, making this an attractive option for working couples.

Continuous Residence and Absence Rules

Both Appendix EU and Appendix Skilled Worker impose continuous residence rules, but the statutory standards differ significantly:

└─────────────────────────────────────┴──────────────────────────────────────┘

Under Appendix Continuous Residence for Skilled Worker ILR applications, caseworkers review travel history across the entire qualifying five-year period. Absences must not exceed 180 days in any rolling 12-month window. Any period exceeding 180 days resets the qualifying clock to zero, requiring the worker to complete a fresh five-year period of continuous lawful stay before applying for settlement.

Transitional Salary Rules and SOC Code Transitions

For EU workers who held lawful permission as a Skilled Worker before 4 April 2024, transitional protections apply under Paragraph SW 4.2 of Appendix Skilled Worker. When these individuals apply to extend their stay, change sponsors, or apply for settlement before 4 April 2030:

• The general salary threshold is pegged at £29,000 rather than £38,700.
• The occupational going rates are calculated based on the 25th percentile of the 2023 Annual Survey of Hours and Earnings (ASHE) rather than the 50th percentile applied to post-April 2024 new arrivals.
• If the worker changes roles to a new SOC code, the new code must still be eligible under the transitional framework, and the salary must meet the transitional going rate for that specific occupation.

Employers must correctly select the transitional salary option when assigning a CoS on the SMS to ensure the caseworker applies the correct legal threshold.

Employer Duties, Licence Suspensions, and Revocations

Sponsor licence holders are subject to compliance audits by UKVI compliance officers, which may occur announced or unannounced. Key ongoing obligations include:

• Reporting Absences and Departures: The sponsor must report via the SMS within 10 working days if a sponsored EU worker fails to start their job, is absent from work for more than 10 consecutive working days without permission, resigns, or is dismissed.
• Reporting Salary and Role Changes: Any significant change in core job duties, workplace location, or salary reductions (which must not fall below the applicable threshold) must be reported via the SMS within 20 working days.
• Record-Keeping: Employers must maintain copies of the worker's passport, current eVisa share code verification, employment contracts, payroll records showing gross and net pay, and recruitment evidence as prescribed by Appendix D.

If UKVI discovers compliance failures during an audit, it can downgrade the sponsor licence from an A-rating to a B-rating (imposing an action plan and barring new sponsorship), suspend the licence pending investigation, or immediately revoke the licence. Revocation results in the cancellation of all sponsored visas, leaving affected workers with 60 calendar days to secure an alternative sponsor or leave the UK.

Switching Immigration Routes In-Country

EU citizens currently residing in the UK under alternative immigration categories can switch into the Skilled Worker route from within the UK, provided their current leave is not under an excluded category. Permitted and excluded switching routes include:

• Graduate Visa to Skilled Worker: Permitted at any point during the Graduate visa's validity. Applicants can qualify as new entrants for up to three years of cumulative stay across both routes.
• Student Visa to Skilled Worker: Permitted only if the student has completed their course of study, or if undertaking a PhD, has completed at least 24 months of study toward that degree.
• Youth Mobility Scheme / Temporary Work: Permitted to switch directly into the Skilled Worker route from within the UK without departing.
• Excluded Categories: Individuals holding permission as a Visitor, Short-Term Student, Seasonal Worker, or Parent of a Child at School cannot switch into the Skilled Worker route in-country; they must depart the UK and submit an entry clearance application from abroad.

Timing, CoS Validity, and Application Windows

Careful calendar management is required to avoid application invalidity:

• Defined CoS Allocation: Once granted by UKVI, a Defined CoS must be assigned to the specific applicant within three months, or it will be automatically cancelled by the system.
• Assigned CoS Validity: Once assigned, the Certificate of Sponsorship remains valid for a maximum of three months. The applicant must submit their online visa application before the CoS expires.
• Employment Start Dates: A visa application cannot be submitted more than three months before the proposed employment start date stated on the CoS. If the application process is delayed and the CoS start date passes, the sponsor must add a sponsor note to the CoS via the SMS stating an updated, realistic start date before the caseworker determines the application.

Summary and Next Steps

Navigating the UK immigration landscape post-Brexit requires careful adherence to statutory thresholds, strict procedural timelines, and rigorous compliance systems. Employers must maintain valid sponsor licences and right to work processes, while EU citizens must ensure their immigration status is secured through the EU Settlement Scheme or the points-based system.

Organisations planning to hire EU talent should conduct an internal audit of their recruitment requirements, verify the appropriate SOC 2020 codes and salary levels, and secure required sponsor licence allocations well in advance of proposed employment start dates. For complex cases involving late EUSS applications, transitional salary protections, or sponsor compliance audits, seeking specialist legal advice ensures applications meet Home Office evidentiary standards.
