The FCA investigation process explained

The Financial Conduct Authority (FCA) has a structured approach to investigating suspected regulatory breaches and financial misconduct. While each case will differ depending on its complexity, most FCA investigations follow a broadly defined process from initial assessment through to potential enforcement action.

Understanding how this process works can help firms and individuals respond effectively and manage regulatory risk at every stage.

For a broader overview, see our guide to FCA Investigations.

Initial assessment and case opening

FCA investigations typically begin with an initial assessment of available information.

This may arise from whistleblower reports, market monitoring, regulatory data or supervisory activity. At this stage, the FCA evaluates whether the matter justifies further action and whether opening a formal investigation is appropriate.

If the regulator determines that enforcement action may be necessary, it will formally appoint investigators.

Appointment of investigators

Once a formal investigation is opened, the FCA appoints investigators under its statutory powers.

Firms or individuals may receive a Notice of Appointment of Investigators, confirming that the regulator has begun a formal investigation. This document may outline the scope of the investigation and the relevant regulatory provisions under consideration.

At this point, it is important to seek legal advice and begin preparing for engagement with the regulator.

Information gathering and evidence collection

A significant portion of the FCA investigation process involves gathering evidence.

The FCA has wide-ranging powers to require the production of documents and information. This may include:

• Internal communications;
• Transaction records;
• Compliance documentation; and
• Policies and procedures.

The regulator may also request information from third parties where relevant.

Failure to comply with FCA information requests can lead to further regulatory action.

Interviews and testimony

Interviews are a central part of many FCA investigations.

The FCA may conduct:

• Voluntary interviews, where individuals are invited to provide information; or
• Compelled interviews, where individuals are required to attend and answer questions under statutory powers.

The distinction between these types of interviews is important, particularly in relation to legal rights and how evidence may be used.

Given the potential implications, individuals should seek legal advice before attending any FCA interview.

Ongoing assessment and case development

Throughout the investigation, the FCA will assess the evidence it has gathered and refine its understanding of the case.

This stage may involve:

• Analysing documents and communications;
• Conducting further enquiries;
• Engaging with other regulators or authorities; and
• Considering whether additional lines of investigation are required.

Investigations can evolve significantly over time, particularly in complex or cross-border matters.

Warning Notices and representations

If the FCA believes enforcement action may be appropriate, it may issue a Warning Notice.

This document sets out the regulator’s preliminary findings and the action it proposes to take. Recipients have the opportunity to make representations and respond to the FCA’s case.

This stage is critical, as it provides an opportunity to challenge the regulator’s position before a final decision is made.

Decision Notices and final outcomes

Following the consideration of any representations, the FCA may issue a Decision Notice confirming its intention to take enforcement action.

If the matter proceeds, a Final Notice may be published, setting out the outcome of the investigation and any sanctions imposed.

Possible outcomes include:

• Financial penalties;
• Public censure;
• Prohibition orders;
• Restrictions on business activities; and
• Referral for criminal prosecution.

How long does an FCA investigation take?

The duration of an FCA investigation can vary significantly.

Some investigations may be resolved within months, while more complex cases involving multiple parties or jurisdictions can take several years. Factors influencing the timeline include:

• The complexity of the issues involved;
• The volume of evidence;
• The number of individuals or firms under investigation; and
• Whether criminal proceedings are involved.
