External bookkeepers are considered 'relevant persons' under the scope of the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (the MLRs).

Therefore, if you are providing a bookkeeping service to clients, or are seen as carrying out bookkeeping 'by way of business', you must:

    • be supervised by an HM Treasury appointed supervisory authority, such as ICB
    • put in place certain controls to identify, prevent and report money laundering offences – known as anti-money laundering or AML

Anti-Money Laundering Supervision (AML)

Members with an ICB Practice Licence are automatically supervised by ICB under the MLRs. As an ICB Practice Licence holder, compliance with the MLRs is dependent on you satisfying the requirements of the MLRs as well as ICB requirements as your supervisor. Please refer to the printable AML To Do List download for more information.

Approval of beneficial owners, officers and managers (BOOMs) – reviewing criminal records

ICB must check that supervised practices comply with Regulation 26 and that all beneficial owners, officers and managers (BOOMs) do not have a relevant criminal conviction.

ICB can only approve a BOOM if we have received a basic criminal record check certificate for them.

Every newly appointed BOOM must obtain a criminal record check at the time they become a BOOM and provide it to us for approval.
