Financial Conduct Authority (FCA) Investigation & Enforcement Solicitors
The Financial Conduct Authority (FCA) has extensive powers to investigate firms and individuals it suspects of misconduct, breaches of regulatory standards, or failures in systems and controls.
An FCA investigation can have serious consequences, including public censure, significant financial penalties, restrictions on permission, and personal action against senior managers.
If you are expecting or facing a FCA investigation, it is important that you seek expect legal advice immediately from our specialist Team. We help regulated businesses, senior managers, certified staff and approved persons navigate FCA scrutiny with clarity, precision and confidence.

What powers does the FCA hold?
Put simply, the FCA has all the power it needs to:
- Make the rules for financial services
- Investigate any claims that those rules are being broken
- Enforce those rules through the civil or criminal courts if needed.
The FCA’s Enforcement & Financial Crime Division is responsible for detecting and investigating anyone who seems to have broken the law or disobeyed their regulations.
Crimes that fall under FCA criminal investigations are very wide reaching. They include:
- Insider dealing
- Misleading statements and practices
- Breach of money laundering regulations
- Conducting a regulated activity without authorisation from the FCA
- Illegal share schemes or 'scams' or 'boiler rooms'
- Unlawful financial promotions.
The FCA has wide-reaching powers and can:
- Investigate all your financial dealings
- Force you to attend compelled interviews
- Interview you under caution for criminal offences
- Force you to hand over requested information and documents
- Punish you for breaking rules by fining you or taking away permissions for you to continue to offer financial services
- Take you to the civil courts, or to the criminal courts for certain criminal offences.
