1.1 This procedure sets out how the regulatory authority will conduct investigations into the building control profession. The regulatory authority for:

England, is the Building Safety Regulator (BSR)

Wales, are the Welsh Ministers, who have delegated this function to BSR in respect to registered building inspectors and registered building control approvers only

1.2 It guides the planning, conduct and concluding of investigations into potential professional misconduct or contraventions by the building control profession.

1.3 The building control profession includes individuals and organisations. We refer to them as ‘professionals’ or ‘the profession’.

1.4 The regulatory authority investigates to:

collect evidence that is sufficient to effectively inform enforcement decision- making on contraventions or professional misconduct and is admissible at court or tribunal

determine whether a contravention or professional misconduct occurred

hold the responsible professional to account, appropriately and proportionately

1.5 The regulatory authority will enable those under investigation to make representations before concluding our investigation.

1.6 Investigations may lead to the resolution of the concerns raised, recommend improvements, result in sanctions or bring about formal enforcement action.
