As a Principal Inspector you will need to demonstrate leadership skills with managerial experience and an excellent track record in the execution of the technical tasks carried out by Inspectors.

As ambassadors of the Inspectorate, Principal Inspectors are expected to identify and deliver change through the use of project management, so as to maintain the credibility of the regulatory regime and ensure that the Inspectorate remains a leading proponent of better regulation.
