An employers right to work check is a mandatory legal verification process that businesses operating in the UK must carry out before hiring any individual, ensuring prospective employees possess the legal immigration status to undertake paid work and establishing a vital statutory excuse against civil penalties.

For small business owners and managers, navigating evolving digital verification protocols and forthcoming regulatory adjustments is essential to protecting operations and maintaining full legal compliance.

• Use Home Office online share codes for non-UK citizens holding eVisa status to verify identity securely.

• The legal definition of an employer and verification scope expands significantly starting on 1 October 2026.

• Retain clear electronic or physical records for the entire duration of employment plus two years afterward.

How to do an employers right to work check?

Executing a legally sound verification requires following a precise, three-stage operational workflow before the candidate commences work.

• Stage 1: Obtain: Gather original, valid identity documents directly from the prospective employee, or request a secure digital share code before their official start date.
• Stage 2: Check: Verify the validity of the documents in the physical presence of the candidate or via the official Home Office online portal. Ensure that photographs are a true likeness, document details match the applicant, and any work restrictions or visa expiration dates are carefully noted.
• Stage 3: Retain: Securely store copies of the verified documents, record the precise date the check took place, and maintain these files safely for audit purposes throughout the duration of employment and for two years following termination.

Adhering to this structured sequence ensures that small business operators satisfy all baseline regulatory duties under UK employment law.

Are right to work checks mandatory for UK employers?

Carrying out right to work checks is a strict legal requirement for all employers operating in the UK, regardless of business size or sector.

Under the statutory framework overseen by the Home Office and anchored in the Immigration, Asylum and Nationality Act 2006, organisations have a legal obligation to prevent illegal working by verifying that every candidate holds valid employment eligibility.

Failing to perform these checks before onboarding leaves a business exposed to unmitigated legal risk. Compliance is universal for all startups, micro-enterprises, and established firms recruiting within the UK market.

Executing checks correctly establishes a statutory excuse, which acts as a complete legal defense against substantial civil penalty fines if an individual is subsequently found to be working unlawfully.

What changes are coming to right to work checks on 1 October 2026?

Significant regulatory changes take effect on 1 October 2026 under provisions originating from the Border Security, Asylum and Immigration Act 2025, substantially widening the scope of compliance obligations for UK businesses.

Change Area	Previous Legal Position	Position From 1 October 2026
Workforce Scope	Restricted strictly to individuals working under a traditional contract of employment.	Expanded to include certain workers' contracts, individual subcontractors, and platform-based gig economy services.
Supply Chain Liability	Liability rested exclusively with the direct employer of the individual worker.	Introduction of extended liability, where civil penalties can reach further up a contractual chain.
Digital Verification	Reliance on general digital identity service providers without specific tier rules.	Digital verification providers must be registered on the Office for Digital Identities and Attributes register specifically for right to work services.

These incoming adjustments mean that businesses engaging non-standard labor models, agency personnel, or casual workers must audit their onboarding policies well ahead of the implementation deadline.

How long should employers keep right to work check records?

Maintaining proper document retention schedules is a core component of long-term compliance and audit readiness.

• Store all verified physical document copies, digital check confirmations, and recorded verification dates securely in electronic or paper personnel files.

• Preserve these records for the entire duration of the individual’s employment relationship with the business.

• Continue holding the archived right to work records for a mandatory minimum period of two years after employment officially terminates.

• Ensure all data storage practices strictly comply with data protection regulations and internal confidentiality policies.

Holding records for this designated window ensures the business retains its active statutory excuse if audited by immigration enforcement officers after an employee leaves.

If an internal dispute or procedural review leads to a formal suspension from work pending investigation, keeping these compliance trails intact helps safeguard the organization against compounded employment tribunals.

What happens if an employer fails to carry out a right to work check?

Neglecting to perform correct verification procedures exposes companies to severe financial and operational consequences enforced by the Home Office.

• Civil Penalties: Businesses face escalating financial fines per illegal worker, with penalties multiplied significantly for repeat infractions within a three-year compliance window.

• Reputational Damage: Public enforcement action can severely damage a small brand’s market standing, client trust, and commercial partnerships.

• Director Prosecution: In instances of deliberate non-compliance or systemic negligence, company directors face criminal prosecution, unlimited fines, or custodial sentences.

• Sponsor Licence Revocation: Firms holding a sponsor licence risk immediate revocation of their status, halting any capacity to employ international talent.

Implementing rigorous internal reviews ensures compliance gaps are caught before regulatory authorities initiate enforcement measures.

What are the most common employer right to work check mistakes?

Avoiding frequent administrative oversights protects organisations from accidental compliance failures during routine recruitment cycles.

• Accepting scanned PDF copies or photographs of passports for manual checks instead of inspecting authentic, original physical documents.

• Failing to track visa expiration dates for team members with time-limited permission to remain, leading to lapsed statutory excuses.

• Relying on unverified digital third-party providers that lack proper authorisation on the Office for Digital Identities and Attributes register.

• Omitting follow-up checks when required or applying checks selectively in a manner that breaches fair recruitment principles.

Conclusion

Ensuring full right to work compliance requires a structured approach to daily recruitment and long-term record-keeping.

To prepare effectively, audit current onboarding workflows, verify that digital vendors meet upcoming authorisation requirements, and establish automated review schedules for team members holding time-limited immigration status.

Proactive administrative management remains the most effective defense against regulatory penalties and operational disruption.
