DPB (Investment Business) Handbook

The DPB (Investment Business) Handbook provides full details of ICAEW's licensing arrangements.

This includes:

  • the agreement between the firm and ICAEW for a licence;
  • the regulated activities that can be conducted under a licence; and
  • how regulated work should be conducted. 

New DPB (Investment Business) Handbook effective 1 June 2023

The regulations have been updated due to changes to ICAEW’s disciplinary framework. The amendments are consequential changes only. (For example, some committee names and references to specific Disciplinary Bye-laws have been updated.) 


The implementation of the Insurance Distribution Directive (IDD) in the UK means that changes have had to be made to the DPB (Investment Business) Handbook, effective from 1 October 2018. These changes have been approved by the Financial Conduct Authority.
