Our Board
Monzo Bank Holding Group Limited (MBHG) was formed on 6 April 2023, and is the parent company of the Monzo Group, which includes Monzo Bank Limited (MBL).
We currently use a mirrored board structure, meaning the directors appointed to the MBHG Board and the MBL Board are the same (with the exception of their Chief Financial Officers). Since 6 April 2023, new directors have joined both boards simultaneously, as the strategic activities of both companies at present are closely aligned. Prior to this date, directors held a single appointment to the MBL Board.
