Professional Corporate Investigations Across the UK

Any criminal incidents should be reported to police on 101. In an emergency always call 999 in the UK.

At On The Case, we provide discreet and professional internal investigations to help businesses address workplace misconduct, employee fraud and policy breaches. Our experienced investigators — all former police officers — deliver clear, factual evidence that allows organisations to act confidently and lawfully when sensitive issues arise.

We work with employers, HR teams and legal professionals to uncover the truth while protecting employees’ rights and maintaining compliance with Data Protection law.

When Internal Investigations Are Needed

Workplace misconduct can take many forms, from minor policy breaches to serious fraud, harassment or theft. Ignoring these issues can damage morale, financial performance, and organisational reputation.

Our services are appropriate for:

• Employee theft, fraud or misuse of company property

• Harassment, bullying or discrimination complaints

• Sickness and absenteeism fraud

• Data breaches, information misuse or unauthorised disclosure

• Policy violations, conflicts of interest or misconduct

We provide impartial, evidence-based investigations that help you make informed decisions.
