OPBAS supervises the 25 professional body supervisors (PBSs) in the legal and accountancy sectors. Find out more about the organisation and its work.
The Government established OPBAS as part of its reforms to strengthen the UK's anti-money laundering (AML) supervisory regime.
Who we are
OPBAS is housed within the FCA and our key objectives are to reduce the harm of money laundering and terrorist financing by:
- ensuring a robust and consistently high standard of supervision by the PBSs overseeing the legal and accountancy sectors
- facilitating collaboration and information and intelligence sharing between PBSs, statutory supervisors and law enforcement agencies
The OPBAS Regulations 2017[2] give us powers to ensure that PBSs meet the standards required by the Money Laundering Regulations 2017[3] (MLRs).
The Government has made a decision to reform the UK AML supervision regime. Read further information.[4]
OPBAS sourcebook
Our sourcebook provides guidance for PBSs on how they can meet their obligations:
We've analysed our progress so far in our 2019[6], 2020[7], 2020/21[8] and 2022/23[9] reports.

Beware scams
If you get an email, letter or phone call from someone claiming to work for us, it’s important you consider the possibility that it could be scam. OPBAS would never ask you to transfer money to us. We would also never ask for sensitive banking information, such as bank account PINs and passwords. Find out more about fake OPBAS/FCA emails.

What OPBAS does not supervise
- 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 PBSs outside the UK
- the adequacy of any functions performed by PBSs 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 PBS
An entity wishing to become a PBS must apply to us using the application form[10] and accompanying notes[11].
We 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.
OPBAS report: Progress and themes from our 2023/24 supervisory work
We have published findings[12] on the progress made by PBSs in tackling money laundering as of July 2024.
The report finds that most PBSs continue to comply with the requirements set out in the Money Laundering Regulations 2017, but pockets of ineffectiveness remain. The report also highlights OPBAS activities undertaken in the 2023/24 supervisory cycle.
OPBAS is fully committed to playing a strong role in reducing and preventing economic crime and we will continue to take proactive actions to address identified shortcomings and drive further improvements in the consistency and effectiveness of PBSs.
Suspicious Activity Report (SAR) work
In April 2025[13] and September 2025[14], we wrote to PBSs with our views following phased and targeted work on SARs quality.
Reg 46A reports
PBSs are required under Regulation 46A of the Money Laundering Regulations 2017 to publish annual reports detailing their anti-money laundering/counter terrorist financing supervisory activities.
We have published joint OPBAS and HM Treasury letters sent to PBSs relating to these reports:
TCSP review
We have published findings from a multi-PBS project on Trust and Company Service Provider (TCSP) risk[18].
Evidence has shown that TCSPs can be exploited to allow millions to be laundered through the UK’s financial system. Our report aims to help legal and accounting professional bodies improve their supervision of their respective sectors, as they play a crucial role in preventing financial crime.
We will continue to work with the wider financial crime community to make sure the findings contained in this report help deliver a stronger and more consistent standard of TCSP supervision.
Risk identification and verification work
We wrote[19] to PBSs with our views in June 2023, following work focused on risk identification and verification.
Conveyancing risk work
We wrote[20] to PBSs with our views in November 2024, following targeted work on money laundering risk within conveyancing.
SRA consultation on financial penalties
We view the Solicitors Regulation Authority (SRA), and all PBSs, as playing an essential role in reducing the risk of money laundering through the effective supervision of its members.
In our 2020/21 report[21] we observed gaps in most PBS enforcement frameworks. We expect:
- all PBSs to ensure that their members are liable to effective, proportionate and dissuasive disciplinary action
- the SRA, and PBSs more generally, to establish a credible and robust fining framework
In November 2021, the SRA consulted[22] on its approach to financial penalties. In March 2022, we wrote[23] to the SRA with our view on this consultation.
Professional Enablers Strategy
Tackling Professional Enablers is a core commitment within the UK’s second Economic Crime Plan 2023.
A strategy[24] designed to galvanise a whole system response to reducing the threat has been developed by the National Economic Crime Centre (NECC) and OPBAS in close partnership with HM Government, supervisory bodies, law enforcement, the Crown Prosecution Service and private sector.
