Financial Services Investigations & Enforcement

Peters & Peters regularly advises firms and individuals subject to financial services investigation and enforcement by regulators including the Financial Conduct Authority (FCA), the Prudential Regulation Authority (PRA) and the Payment Systems Regulator (PSR).

We are known for achieving outstanding results for individuals and firms accused of misconduct. We also advise clients conducting internal investigations in respect of potential misconduct and making initial reports to the regulators. Peters & Peters is able to advise clients from first contact with a regulator to outcome in both criminal and contentious regulatory matters.

Chambers 2024 says we are “well-known financial crime practice, and one of the earliest firms to establish itself in this field”. In Legal 500 2025, a client said, “All members of the team are bright, efficient, thoughtful, and responsive. Every matter is given the attention it needs in a timely manner.”

We are particularly known for our work where criminal and regulatory law intersect, and for representing individuals who are witnesses or subjects in investigations.

Our expertise includes:

Representing FCA, PRA and PSR investigation subjects and witnesses.
Advising clients in respect of concurrent civil, regulatory and criminal enforcement actions and acting for individuals subject to criminal restraint and world freezing orders.
Advising clients subject to pre-investigation enquiries wishing to avoid the opening of a formal investigation.
Attending investigation interviews and meetings before regulators’ decision committees.
Representing clients in enforcement hearings in the Upper Tribunal (Tax and Chancery Chamber), as well as proceedings in the Crown Court and High Court.
Providing advice to corporates and individuals in crisis, particularly on discovery of potential misconduct. This includes breaches of the General Prohibition, and connected collateral issues, such as addressing proceeds of crime issues and ongoing remediation.
Making discloses to regulators where appropriate and the management of ongoing communications.
Collateral investigation issues such as asset forfeiture, requests on behalf of overseas regulators and authorisation applications and regulatory references, following adverse findings.

We also provide advisory services for firms wishing to review and enhance their Corporate Compliance programmes, particularly in relation to systems and controls to prevent financial crime.

Our Business Crime team contains former FCA enforcement lawyers, so our advice is based on a deep understanding of the FCA’s approach to regulation.

We combine a robust approach to enforcement proceedings with an understanding of the need to be open and co-operative with the regulator. This has enabled us to achieve excellent outcomes for our clients, including no further action being taken on suspected insider dealing and other criminal cases, the FCA pursuing regulatory rather than criminal proceedings, and the minimisation of penalties and prohibitions.
