Professional Corporate Fraud and Theft Investigations Across the UK

At On The Case, we help businesses uncover and resolve cases of internal fraud and theft with discretion and precision. Our experienced investigators — all former police officers — use proven investigative methods to identify how losses occurred, gather evidence and support management in taking decisive, lawful action.

Fraud and theft can damage far more than the balance sheet. They erode trust, harm staff morale and threaten the integrity of your organisation. We provide the clarity and evidence you need to address the issue and prevent further loss.

When to Consider a Fraud or Theft Investigation

Even well-managed organisations can be vulnerable to internal misconduct. Warning signs often include unexplained financial discrepancies, missing stock or irregular staff behaviour.

You may need our assistance if you suspect:

• Employee theft or misuse of company property

• Misuse of company cards, fuel or expenses

• Collusion between employees and external parties

• Stock, tools or equipment going missing

• Theft from company vehicles or work sites

• Unauthorised use or removal of materials

• False overtime or timesheet claims

• Abuse of company resources or client information

Our investigations are conducted discreetly, objectively and in full compliance with UK law.
