Civil Penalties for Illegal Working: Employer Guide 2026 | Paragon Law

Understanding the Civil Penalty Regime

What 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 UK

• Previously had permission, but their immigration status expired

• Was working in breach of their visa conditions, such as exceeding permitted working hours or undertaking prohibited employment

Importantly, 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 Employers

Increased Penalty Levels

Since February 2024, the financial consequences of non-compliance have increased substantially.

Civil Penalty Levels at a Glance

For employers with multiple affected workers, penalties can quickly escalate into six-figure sums, creating a significant and unexpected financial burden.

The Wider Business Consequences

Whilst 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 scrutiny

• Difficulties obtaining a sponsor licence

• Sponsor licence suspension or revocation

• Reputational damage

• Disruption to recruitment plans

• County Court enforcement action where penalties remain unpaid

For businesses that rely on international recruitment, the longer-term commercial impact can exceed the value of the penalty itself.

How Civil Penalties Can Escalate Quickly

Consider 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 Arise

Home Office Compliance Visits

Many civil penalty cases begin with a Home Office compliance visit.

During these inspections, officers may:

• Review personnel files and HR records

• Examine right to work documentation

• Interview managers and employees

• Investigate allegations of illegal working

Following a visit, employers may receive a Civil Penalty Referral Notice indicating that the Home Office is considering enforcement action.

The Information Gathering Stage

Before 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 checks

• Employment records

• Relevant immigration documentation

• Evidence supporting any mitigating circumstances

A 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 Penalty

Do Not Assume the Home Office Is Correct

A 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 Objection

Employers may object to a Civil Penalty Notice on three principal grounds.

1. You Are Not the Employer

In some situations, the worker may actually be employed by:

• An employment agency

• Another group company

• A third-party labour provider

• A genuinely self-employed contractor

Where liability has been attributed to the wrong organisation, the penalty may be challenged.

2. You Have a Statutory Excuse

Employers 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 Excessive

The 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 Decision

A Significant Development for Employers

In 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 Implications

Employers who receive a Civil Penalty Notice should carefully examine whether:

• The alleged breach is clearly identified

• The legal basis for liability is properly explained

• The facts relied upon by the Home Office are clearly set out

• The notice enables the employer to understand and respond to the allegations being made

Whilst the judgment does not automatically invalidate all previously issued penalties, it may provide an important ground of challenge in appropriate cases.

Practical Tip

If 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 Reductions

Factors That May Reduce a Penalty

The Home Office may reduce penalties where an employer can demonstrate:

• Active cooperation with an investigation

• A history of reporting suspected illegal working

• Effective right to work checking systems

• Strong compliance procedures and recordkeeping practices

Evidence of a genuine commitment to compliance may influence how the Home Office assesses both liability and penalty levels.

Warning Notices Instead of Financial Penalties

In 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 Discounts

Employers 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 Proactive

The Statutory Excuse Remains the Best Protection

For 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 begins

• Carrying out follow-up checks where permission is time limited

• Maintaining dated records of all checks

• Training HR teams and managers responsible for recruitment

• Implementing regular compliance reviews and audits

Many 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 Critical

One 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 checked

• When it was checked

• Who carried out the check

• The outcome of the check

Without 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 Checklist

Employers 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?

Concerned About Your Right to Work Compliance?

 

Many employers only discover weaknesses in their right to work procedures when the Home Office conducts a compliance visit or enforcement action is already underway.

A proactive compliance audit can help identify risks, strengthen processes and reduce the likelihood of costly penalties before issues arise.

Our Business Immigration team helps employers strengthen compliance procedures, prepare for Home Office scrutiny and respond to Civil Penalty Referral Notices and Civil Penalty Notices. Get in touch to discuss a compliance audit or review of your existing right to work processes.

Final Thoughts

With 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 Questions

What 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. Employers do not need to knowingly employ an illegal worker to face a civil penalty. Liability can arise where compliant right to work checks were not completed correctly or cannot be evidenced.

What is a statutory excuse?

A statutory excuse is the legal protection available where an employer has carried out the required right to work checks correctly and retained the appropriate evidence. Where a valid statutory excuse exists, the employer may avoid civil penalty liability.

Can I challenge a Civil Penalty Notice?

Yes. Employers can challenge a Civil Penalty Notice where they are not the employer, have established a statutory excuse or believe the penalty has been issued or calculated incorrectly.

How long do employers have to challenge a Civil Penalty Notice?

Employers generally have 28 days from receipt of a Civil Penalty Notice to submit an objection. Strict deadlines apply.

Can a right to work check become invalid?

Yes. A right to work check can lose its protective value if required follow-up checks are not completed or the employer cannot produce evidence showing the original check was carried out correctly.

Can a civil penalty affect a sponsor licence?

Yes. A civil penalty can lead to increased Home Office scrutiny and sponsor licence compliance action. In serious cases, it may contribute to sponsor licence suspension or revocation and affect an organisation's ability to recruit overseas workers.

Can I appeal if my objection is unsuccessful?

Yes. Employers can appeal to the County Court, although this carries potential costs consequences and should be considered carefully. 

Does using an agency remove liability?

Not necessarily. Liability depends on who is legally considered the employer and the specific circumstances of the arrangement.

What should I do if I receive a Civil Penalty Referral Notice?

Seek advice as early as possible. Early intervention can help employers gather evidence, establish any available statutory excuse and present mitigating factors before a final decision is made.

What is the best defence against a civil penalty?

The strongest protection remains conducting compliant right to work checks before employment begins and maintaining clear records demonstrating those checks were completed correctly.
