BOOM declaration

The Money Laundering Regulations 2017 (MLR2017) require the IAB to approve any Beneficial Owner, Officer or Managers (referred to as a BOOM – as defined below) of an IAB supervised firm/practice.

The IAB will not approve any BOOM who has been convicted of a relevant offence as defined by Schedule 3 of the MLR2017 (listed here).  It is a criminal offence, punishable by up to a two year custodial sentence and/or financial penalty, to hold a position as a BOOM with a relevant unspent conviction.

An IAB supervised firm or practitioner must take reasonable steps to ensure that no one is appointed to be, or continues to act as, a BOOM who has a relevant unspent criminal conviction.

In order to comply, the IAB requires all BOOMs in supervised firms to complete a basic criminal record check via the relevant organisation, depending on where they live and work:

Members in Practice have an ongoing duty to inform the IAB if a BOOM is appointed to their firm/practice, and to confirm that the appropriate criminal record check has been conducted with satisfactory result.

Members must take reasonable ongoing steps to ensure that BOOMs declare any subsequent relevant convictions to an appointed person within the firm.

Should a firm be made aware that a BOOM has a relevant conviction, the IAB must be notified of the fact within 30 days by emailing
