Office for Professional Body Anti-Money Laundering Supervision (OPBAS)

The Government established OPBAS as part of its reforms to strengthen the UK's anti-money laundering (AML) supervisory regime. OPBAS supervises the 25 professional body supervisors in the legal and accountancy sectors.

OPBAS is housed within the FSAEU and its key objectives are to reduce the harm of money laundering and terrorist financing by:

  1. Ensuring a robust and consistently high standard of supervision by the professional body AML supervisors (PBSs) overseeing the legal and accountancy sectors.
  2. Facilitating collaboration and information and intelligence sharing between PBSs, statutory supervisors and law enforcement agencies.

The OPBAS Regulations 2017 give OPBAS powers to ensure the professional body AML supervisors meet the standards required by the Money Laundering Regulations 2017 (MLRs).

The OPBAS sourcebook provides guidance for professional body AML supervisors on how they can meet their obligations:

  • members of professional bodies, such as firms, accountants and solicitors, or any other type of business subject to the requirements of the MLRs
  • statutory anti-money laundering supervisors such as the Gambling Commission and HM Revenue and Customs
  • activity carried out by professional body supervisors outside the UK
  • the adequacy of any functions performed by professional body supervisors unrelated to AML supervision, including any oversight of their members’ controls over other types of financial crime, such as those related to the prevention of fraud, improving data security and the implementation of financial sanctions and asset freezes

Becoming a professional body supervisor

An entity wishing to become a professional body supervisor must apply to OPBAS. Applications can be made using the application form and accompanying notes.

OPBAS will consider whether the relevant entity meets the standards expected of AML supervisors set out in the MLRs, and will recommend to the Treasury whether the legislation should be amended to assign a formal role for the entity.
