What We Do

There is growing pressure for businesses to bear the cost of investigating themselves, through what is known as an ‘internal investigation’.

This can help avoid any investigations by external agencies, which can take time and disrupt your business.

Our team are experts in corporate investigations and can help you conduct an internal investigation, or assist you when responding to a regulator or law enforcement agency.

Why Choose Irwin Mitchell?

Our expert team help many individuals and firms to conduct an internal investigation of their company, as well as advising on the various response options available to any external regulators and law enforcement agencies. We regularly come into contact with The Serious Fraud Office (SFO), the Financial Conduct Authority (FCA) and the Dept for Business, Energy & Industrial Strategy (BEIS).

If consulted early enough, we can also assist with internal audits, training and provide compliance advice to prevent a company becoming the victim of financial crime.

We can help you with:

  • Reporting to prosecutors and regulators
  • A deferred prosecution agreement
  • Responding to compulsory information requests
  • Understanding the conduct of an internal investigation
  • Establishing whether there has been any unlawful conduct
  • Gaining immunity from prosecution (if possible)
  • Undertaking civil action to recover any losses

If you wish to conduct an internal investigation, or need help to avoid an external investigation, you should seek immediate expert legal advice.
