BSB Handbook Version 5.0 Has Now been Published
Version 5.0 of the BSB Handbook came into force on 15 June 2026, introducing updated complaints handling arrangements and a number of regulatory clarifications. The changes are now live, and they cover more ground than complaints rules alone.
The New First-Tier Complaints Framework
The first-tier complaints handling changes are designed to improve consistency, transparency and confidence in complaints handling across the Bar. In practice, the revised framework changes three things: when and how complaints information must be given to clients, how complaints are managed and resolved internally, and how complaints data is reported to the BSB.
On data, the change is significant. Rule C108.2 mandates the collection and submission of specific complaints data to the BSB. Rule C108.3 requires barristers to inform their chambers or BSB entity of any first-tier complaints they have received, where the work relates to that organisation. Data will be submitted annually via a new MyBar form, and barristers will need to confirm at their annual authorisation to practise that they have provided all relevant complaints information to their set. The first data collection exercise will take place in at least a year's time.
That timeline provides breathing room, but chambers that currently have no structured way of recording first-tier complaints will need to build that infrastructure now. Client-facing changes also apply immediately. New rules rC99B.1 and rC99B.2 define when a barrister must provide a lay client with complaints process information, including at the conclusion of the matter. Engagement letters, terms of work and end-of-matter communications should all be reviewed against these requirements without delay.
Harman Review Guidance Now Embedded in the Handbook
Version 5.0 also incorporates new guidance flowing from the Harman Review on bullying, harassment and sexual harassment at the Bar. Four points now appear directly in the Handbook. Where alleged serious misconduct relates to bullying, harassment or sexual harassment, the duty to report may be satisfied by reporting either to the BSB or to the Bar Council's Commissioner for Conduct, supported by a protocol agreed between them. The BSB recommends making a report where there is a reasonable suspicion that such misconduct occurred. The BSB has clarified that it will not take enforcement action against barristers who have been the subject of this type of misconduct and do not report it - and the same applies to individuals whom the subject has acknowledged as a confidant. The BSB has also clarified that serious instances of bullying may amount to serious misconduct.
The dual reporting route means a barrister who witnesses or is aware of bullying or harassment now has a formal choice of where to report. The non-enforcement assurance for victims and their confidants removes a significant barrier to coming forward. And the explicit confirmation that serious bullying can constitute serious misconduct closes what had previously been treated as a grey area.
Regulatory Clarifications: rC8 and rE44
Rule rC8 has been updated to confirm that the professional duties of honesty, integrity and independence are separate obligations and must each be upheld in their own right. This matters because arguments have previously been made in disciplinary proceedings that a breach of one of these duties does not necessarily constitute a breach of another. The update makes clear that each must be met independently - a barrister cannot satisfy the honesty obligation while failing on independence, or vice versa.
Regulation rE44 has been updated to clarify the BSB's publication policy for disciplinary findings reached through the Determination by Consent procedure. The Determination by Consent process allows cases to be resolved without a full tribunal hearing where a barrister admits the relevant conduct. The clarification to rE44 means barristers considering whether to engage with that process now have greater certainty about when and how findings will be published.
What Chambers Should Do Now
Chambers should treat the coming into force of Version 5.0 as a prompt for four actions: review internal complaints procedures against the revised rules in rC99 to rC109; update client-facing documentation - engagement letters, privacy notices and end-of-matter communications - to reflect the new information obligations; begin designing a system for recording complaints in the data categories the BSB will require at annual submission; and brief chambers members and management on the Harman Review guidance now embedded in the Handbook, particularly the dual reporting pathway and the non-enforcement assurance for victims.
