The main circumstances in which PSAA will consider changing an auditor appointment during the five year compulsory appointing period are either for independence reasons, for example the identification of a conflict of interest involving the existing audit firm, or because of the emergence of new joint working arrangements.
An authority appointing its own auditor will find it more difficult to change their auditor appointment during the contracted period, as this would require the authority to conduct a new selection and procurement exercise. The appointing person scheme therefore provides more flexibility for opted-in bodies.
