such fee as may be determined by the public authority in accordance with regulations made by the Minister for the Cabinet Office.

that any fee is not to exceed such maximum as may be specified in, or determined in accordance with, the regulations, and
that any fee is to be calculated in such manner as may be prescribed by the regulations.
