Our role as an improvement regulator is to strengthen trust in ICAEW Chartered Accountants and firms. We do this by enabling, evaluating and enforcing the highest standards in the profession.

ICAEW’s regulatory and conduct roles are separated from ICAEW’s other activities through internal governance so that we can monitor, support or take steps to ensure change if standards are not met. These roles are carried out by the Professional Standards Department (PSD) and overseen by the ICAEW Regulatory Board (IRB). Read more about our role as an improvement regulator.
