Different scales may be prescribed in respect of the different activities described in subsection (1), different types of the same activity and different types of Welsh improvement authority.

An authority audited, assessed or inspected as mentioned in subsection (1) must, subject to subsection (4), pay to F2the Wales Audit Office, in accordance with a scheme for charging fees prepared under section 24 of the Public Audit (Wales) Act 2013, the fee payable under the appropriate scale.

If it appears to F3the Wales Audit Office that the work involved in a particular audit, assessment or inspection was substantially more or less than that envisaged by the appropriate scale, F3the Wales Audit Office may charge a fee which is larger or smaller than that referred to in subsection (3).

But a fee charged under this section may not exceed the full cost of exercising the function to which it relates.
