Civil Penalties for Illegal Working: Employer Guide 2026Civil penalties for illegal working can reach £60,000 per worker. Learn how employers can reduce risk, challenge penalties and strengthen right to work compliance.Author: Thal VasishtaIntroduction With civil penalties now reaching up to £60,000 per worker, illegal working is no longer simply an HR compliance issue. For many UK employers, it represents a significant financial, operational, and reputational risk.For sponsor licence holders, the consequences can extend beyond financial penalties to include increased Home Office scrutiny, licence action, and disruption to overseas recruitment plans.Against a backdrop of increasing enforcement activity and heightened compliance expectations, employers should ensure that their right to work procedures remain robust, documented, and capable of withstanding Home Office scrutiny. The cost of getting it wrong can be substantial, particularly where multiple workers are involved.This article examines how civil penalties arise, the potential grounds for challenging them, the impact of the Supreme Court's decision in Akbars Restaurant v SSHD, and the practical steps employers can take to reduce risk and strengthen compliance.Key Takeaways Employers can face civil penalties of up to £45,000 per worker for a first breach and £60,000 per worker for repeat breaches within three yearsA civil penalty can affect sponsor licence compliance and future overseas recruitmentEmployers may be able to challenge penalties where liability is disputed, right to work checks were completed correctly or the penalty is excessiveThe Supreme Court's judgment in Akbars Restaurant v SSHD highlights the importance of properly reasoned Civil Penalty NoticesMaintaining evidence of compliant right to work checks remains the strongest defence against enforcement actionUnderstanding the Civil Penalty RegimeWhat Is a Civil Penalty?A civil penalty is a financial sanction issued by the Home Office where an employer is found to have employed an individual who did not have the right to undertake the work in question. Penalties are imposed under the Immigration, Asylum and Nationality Act 2006 and form part of the Government's wider strategy to tackle illegal working.Liability may arise where an individual:Never had permission to work in the UKPreviously had permission, but their immigration status expiredWas working in breach of their visa conditions, such as exceeding permitted working hours or undertaking prohibited employmentImportantly, an employer does not need to knowingly employ an illegal worker to face a civil penalty. Failure to carry out compliant right to work checks, or an inability to demonstrate that checks were completed correctly, can be sufficient to establish liability.The Financial Exposure for EmployersIncreased Penalty LevelsSince February 2024, the financial consequences of non-compliance have increased substantially.Civil Penalty Levels at a GlanceFirst breach: £45,000 per workerRepeat breach within three years: £60,000 per workerFor employers with multiple affected workers, penalties can quickly escalate into six-figure sums, creating a significant and unexpected financial burden.The Wider Business ConsequencesWhilst the headline figures often attract attention, the financial penalty itself is frequently only part of the problem.A civil penalty may also result in:Increased Home Office scrutinyDifficulties obtaining a sponsor licenceSponsor licence suspension or revocationReputational damageDisruption to recruitment plansCounty Court enforcement action where penalties remain unpaidFor businesses that rely on international recruitment, the longer-term commercial impact can exceed the value of the penalty itself.How Civil Penalties Can Escalate QuicklyConsider an employer found to have employed three individuals who did not have the correct permission to work. Even if this represents a first breach, the organisation could face penalties of up to £135,000.Where repeat breaches arise, potential liability could increase to £180,000.In addition to the financial consequences, the employer may face increased Home Office scrutiny, reputational damage, and potential sponsor licence implications.For many organisations, the wider business impact can exceed the value of the financial penalty itself.How Civil Penalties Typically AriseHome Office Compliance VisitsMany civil penalty cases begin with a Home Office compliance visit.During these inspections, officers may:Review personnel files and HR recordsExamine right to work documentationInterview managers and employeesInvestigate allegations of illegal workingFollowing a visit, employers may receive a Civil Penalty Referral Notice indicating that the Home Office is considering enforcement action.The Information Gathering StageBefore a final decision is made, employers are usually invited to provide evidence and representations.This stage should not be treated as a formality. A detailed and well-evidenced response can significantly influence the final outcome.Employers should typically provide:Copies of right to work checksEmployment recordsRelevant immigration documentationEvidence supporting any mitigating circumstancesA prompt and carefully prepared response can often make a material difference to the Home Office's assessment of liability and any subsequent penalty.Early legal advice can be particularly valuable at this stage, helping employers identify potential statutory excuses, address evidential gaps, and present representations effectively.Challenging a Civil PenaltyDo Not Assume the Home Office Is CorrectA civil penalty is an administrative decision rather than a criminal conviction. Like any administrative decision, it may be based on incomplete information, flawed reasoning or an incorrect assessment of the facts.Employers should carefully review both the basis for liability and the calculation of any penalty before making a payment decision.Grounds for ObjectionEmployers may object to a Civil Penalty Notice on three principal grounds.1. You Are Not the EmployerIn some situations, the worker may actually be employed by:An employment agencyAnother group companyA third-party labour providerA genuinely self-employed contractorWhere liability has been attributed to the wrong organisation, the penalty may be challenged.2. You Have a Statutory ExcuseEmployers can often avoid liability if they completed the required right to work checks before employment started and retained the correct evidence.This highlights the importance of maintaining accurate and readily accessible records.3. The Penalty Is ExcessiveThe Home Office may fail to properly account for mitigating factors that could reduce the overall penalty.Employers should review whether the penalty has been calculated correctly and whether all relevant circumstances have been considered.The Importance of the Akbars Supreme Court DecisionA Significant Development for EmployersIn Akbars Restaurant (Middlesbrough) Ltd v Secretary of State for the Home Department [2026] UKSC 26, the Supreme Court confirmed that a Civil Penalty Notice must clearly explain why the employer is considered liable.Historically, some Civil Penalty Notices simply recited alternative legal grounds without identifying the specific basis upon which liability was being alleged. The Supreme Court held that this approach was insufficient.Employers are entitled to understand the precise basis upon which liability is alleged so that they can properly assess whether the decision should be challenged.Practical ImplicationsEmployers who receive a Civil Penalty Notice should carefully examine whether:The alleged breach is clearly identifiedThe legal basis for liability is properly explainedThe facts relied upon by the Home Office are clearly set outThe notice enables the employer to understand and respond to the allegations being madeWhilst the judgment does not automatically invalidate all previously issued penalties, it may provide an important ground of challenge in appropriate cases.Practical TipIf you receive a Civil Penalty Notice, do not assume the Home Office's assessment is correct. Review the notice carefully and seek advice before deciding whether to pay, object or appeal. Early action can significantly improve the options available.The decision also reinforces an important principle: employers should not assume that Home Office decision-making is beyond challenge. Where liability is disputed, organisations should carefully assess whether the Home Office has provided sufficient evidence and reasoning before accepting the penalty.Mitigation and Penalty ReductionsFactors That May Reduce a PenaltyThe Home Office may reduce penalties where an employer can demonstrate:Active cooperation with an investigationA history of reporting suspected illegal workingEffective right to work checking systemsStrong compliance procedures and recordkeeping practicesEvidence of a genuine commitment to compliance may influence how the Home Office assesses both liability and penalty levels.Warning Notices Instead of Financial PenaltiesIn some first-time breach cases, employers with otherwise strong compliance systems may receive a warning notice instead of a financial penalty.Whilst employers should never rely on receiving a warning notice, this possibility highlights the value of maintaining robust right to work procedures before issues arise.Fast Payment DiscountsEmployers facing a first civil penalty may be eligible for a 30% reduction if payment is made in full within 21 days under the Home Office Fast Payment Option.However, before accepting a discount and making payment, employers should carefully consider whether there are valid grounds to challenge either liability or the amount of the penalty.Preventing Civil Penalties: Compliance Must Be ProactiveThe Statutory Excuse Remains the Best ProtectionFor most employers, the most effective protection against a civil penalty is establishing and maintaining a statutory excuse.Key compliance measures include:Conducting right to work checks before employment beginsCarrying out follow-up checks where permission is time limitedMaintaining dated records of all checksTraining HR teams and managers responsible for recruitmentImplementing regular compliance reviews and auditsMany organisations invest significant resources in recruitment and workforce planning but devote less attention to the compliance systems supporting those activities. A proactive approach can significantly reduce the likelihood of enforcement action later. Documentation Is CriticalOne of the most common issues identified during Home Office investigations is not that checks were never carried out, but that employers cannot adequately prove they were completed.The Home Office expects employers to maintain clear and dated records demonstrating:What was checkedWhen it was checkedWho carried out the checkThe outcome of the checkWithout appropriate records, employers may struggle to rely on a statutory excuse even where compliant checks were genuinely undertaken.From a Home Office perspective, a right to work check that cannot be evidenced may provide little practical protection during an investigation.Employer Compliance ChecklistEmployers should regularly assess whether they can answer "yes" to the following questions:✅ Are right to work checks completed before employment begins?✅ Are follow-up checks diarised for workers with time-limited immigration status?✅ Are copies of all right to work evidence retained and dated?✅ Have managers received right to work compliance training?✅ Is there a documented right to work checking procedure?✅ Are internal audits conducted periodically?✅ Is responsibility for compliance clearly assigned within the business?✅ Would your organisation be prepared for an unannounced Home Office compliance visit?Final ThoughtsWith civil penalties reaching up to £60,000 per worker and Home Office enforcement activity continuing to increase, employers should view right to work compliance as a core business risk rather than an administrative exercise.Whilst the Supreme Court's decision in Akbars Restaurant v SSHD provides greater clarity regarding the information employers should expect when a Civil Penalty Notice is issued, organisations should not rely on objections and appeals as their primary line of defence.Robust recruitment procedures, effective recordkeeping, ongoing staff training and regular compliance audits continue to provide the strongest protection against enforcement action. For sponsor licence holders, these measures are particularly important given the potential impact that illegal working findings can have on future sponsorship activities and overseas recruitment plans.Employers that treat right to work compliance as a routine administrative task may be exposing themselves to significant and avoidable risk. As penalties increase and Home Office scrutiny continues, organisations should ensure their compliance processes are regularly reviewed, tested and documented. In many cases, identifying weaknesses early is far less costly than responding to enforcement action later.Frequently Asked QuestionsWhat is the maximum civil penalty for employing an illegal worker?Employers can face civil penalties of up to £45,000 per worker for a first breach and £60,000 per worker for a repeat breach within three years.Can an employer be fined if they did not know a worker did not have the right to work?Yes.
