What Happens if Your Temp Worker Fails a Right to Work Check, and How to Avoid It

Right to Work (RTW) checks have always been a legal requirement for UK employers and recruitment agencies. However, recent changes to enforcement and penalties mean they can no longer be treated as a simple administrative task.

Since April 2025, fines for employing someone without the legal right to work have increased dramatically. For temporary recruitment agencies managing high volumes of workers, a single compliance failure can now result in substantial financial penalties, reputational damage, and in some cases criminal liability.

If your agency is still relying on spreadsheets, manual document checks, and consultants chasing passports, it’s worth taking a closer look at your current process.

What Is a Right to Work Check?

A Right to Work check is a legal requirement for every worker you place in the UK, regardless of nationality, contract type, or assignment length.

Whether you’re placing temporary workers, zero-hours staff, or last-minute shift cover, a compliant RTW check must be completed before the worker starts.

When conducted correctly, a Right to Work check provides what is known as a statutory excuse. This protects your agency from liability if it later emerges that the worker did not have the legal right to work.

There are three recognised methods for conducting checks:

• Manual document checks using original documents
• Home Office online checks using a worker’s share code
• Digital verification through a certified Identity Service Provider (IDSP)

The key requirement is that the check must be completed correctly, documented thoroughly, and carried out before any work begins.

What Happens When a Temp Worker Fails a Right to Work Check?

Not all failed checks are the same. However, every scenario carries compliance implications.

Scenario 1: The Worker Has No Right to Work

This is the most serious situation.

If a candidate cannot provide acceptable evidence of their right to work in the UK, they cannot be placed.

Should your agency knowingly place that worker, or allow them to start before a compliant check is completed, you may face:

• Civil penalties of up to £45,000 per illegal worker for a first offence
• Civil penalties of up to £60,000 per worker for repeat offences within three years
• Potential criminal prosecution where there was knowledge or reasonable cause to believe the worker was ineligible

Recent Home Office enforcement activity demonstrates just how seriously these breaches are being treated. Increased inspection activity and significant fines are becoming more common across sectors that rely heavily on temporary labour.

Scenario 2: The Worker Has Time-Limited Permission

Many temporary workers have legal permission to work in the UK, but only for a limited period.

In these cases, the initial check is not enough.

Agencies must carry out follow-up checks before the worker’s permission expires. Failure to do so means the statutory excuse no longer applies, even if the original check was completed correctly.

For agencies managing hundreds of workers, tracking visa expiry dates manually can quickly become a significant risk.

Scenario 3: The Check Was Completed Incorrectly

One of the most common compliance failures isn’t that the worker lacked permission to work—it’s that the agency failed to conduct the check correctly.

Examples include:

• Collecting the wrong documents
• Failing to retain copies
• Conducting the check after the worker started
• Accepting documents that are no longer valid

Immigration requirements continue to evolve. For example, changes to the use of Biometric Residence Permits (BRPs) have altered how certain workers must prove their right to work. Agencies that fail to keep pace with these changes risk losing their statutory excuse entirely.

What Should You Do If a Candidate Fails?

If a worker cannot provide evidence of their right to work during onboarding, there are several immediate steps your agency should take.

1. Do not place the worker.
2. Request the correct documentation and allow a reasonable opportunity for them to provide it.
3. If they have already started work, suspend the assignment immediately and seek legal advice.
4. Follow any reporting obligations where applicable.
5. Keep a complete record of every action taken.

Documentation is critical. During an audit, evidence matters just as much as the check itself.

The Bigger Risk: Systemic Compliance Gaps

Most agencies can manage the occasional failed check.

The greater threat is discovering during an audit that your processes have been producing non-compliant checks at scale.

Common causes include:

Workers Starting Before Checks Are Complete

The pressure to fill shifts quickly often leads to shortcuts. Unfortunately, this is one of the fastest ways to lose your statutory excuse.

No Follow-Up Process

Time-limited permissions expire quietly. Without automated reminders and workflows, follow-up checks can easily be missed.

Outdated Compliance Knowledge

Rules change regularly. Agencies relying on memory, spreadsheets, or disconnected systems can inadvertently accept documents that are no longer valid.

Lack of Audit Trails

Inspectors expect to see evidence. If records, timestamps, and verification data cannot be produced quickly, your agency may struggle to demonstrate compliance.

Why Digital Right to Work Checks Are Becoming Essential

Digital RTW checks are rapidly becoming the preferred approach for temporary recruitment agencies.

Using a certified Identity Service Provider such as TrustID, British and Irish candidates can verify their identity remotely through secure Identity Document Validation Technology (IDVT).

The process is faster, more accurate, and significantly easier to manage at scale.

For agencies, the benefits are substantial:

• Faster onboarding
• Reduced administrative workload
• Improved candidate experience
• Automatic audit trails
• Lower compliance risk

Most importantly, compliance becomes embedded into the onboarding process rather than treated as a separate administrative task.

How Mobile Rocket Simplifies Compliance

Rocket Recruitment integrates digital Right to Work checks directly into the candidate onboarding journey through our partnership with TrustID.

Candidates complete checks through their agency’s branded app as part of the standard registration process. Verification results are automatically recorded within the CRM, giving consultants real-time visibility of compliance status before shifts are offered.

This means:

• No manual document chasing
• No disconnected systems
• No uncertainty around compliance status
• Complete audit-ready records

The impact of compliance automation is already being felt by agencies using Rocket Recruitment.

S4S Team transformed their compliance process by automating Right to Work checks, references, DBS checks, certification tracking, and document expiry management. The result was a 29.5% increase in billed hours, 18 new clients onboarded within six months, and a successful EAS inspection with no advisories.

The Bottom Line

Right to Work compliance is no longer something agencies can afford to manage manually.

With higher fines, increased enforcement activity, and evolving documentation requirements, a robust compliance process has become a business necessity.

The good news is that the same technology helping agencies improve productivity and candidate engagement can also dramatically reduce compliance risk.

By embedding Right to Work checks into onboarding, automating follow-ups, and maintaining a complete digital audit trail, agencies can protect themselves while creating a faster, more efficient recruitment operation.

Because when compliance is built into the process, there’s far less chance of finding out what happens when things go wrong.
