Section 15 sets out provisions that regulations made by the Treasury under section 14 may or must contain. The intention of these provisions is to set appropriate parameters for the sub-delegation of rulemaking powers from the Treasury to the FCA via regulations.
	Subsection (2) permits regulations to require or enable the FCA to impose any interface requirement that could be imposed by regulations made under section 7(4) or (5), but with the exception that the FCA may not enable or require a person to set up an interface body (only the Treasury may do that via regulations).
	Subsection (3) requires that regulations must specify the purposes which the FCA must advance when exercising functions, matters to which the FCA must have regard, and provisions about the procedure for the making of any FCA interface rules.
	Subsection (4) provides that regulations may impose requirements and make provision in relation to the FCA’s exercise of any sub-delegated rulemaking powers. This might include, for example, requiring the FCA to carry out a cost benefit analysis in relation to the rules, requiring it to modify or waive the rules as they apply in a particular case, or requiring it to publish guidance about how it proposes to exercise its functions.
	Subsection (5) provides that regulations may require or enable the FCA to impose requirements on a person to review conduct, take remedial action and to make redress for loss or damage suffered as a result of misconduct. Subsection (12) clarifies the things that redress may include.
	Subsection (6) allows regulations to require or enable the FCA to make rules about the fees that persons listed in subsection (7) must pay to an interface body or another person listed in that subsection, or someone acting on their behalf, in connection with the activities described in subsection (8). This enables FCA rules to allow participants to charge for, and make profits on, activities done in performance of duties or exercise of powers conferred on the person by or under Part 1 regulations.
	Subsection (7) provides that fees may be required to be paid by persons within section 14(3)(b) or (c) or financial services providers.
	The activities described in subsection (8), for which rules may enable fees to be charged under subsection (6), are performing or exercising duties or powers imposed or conferred on the interface body or persons listed in subsection (7), by Part 1 regulations or by FCA interface rules.
	Subsection (9) includes provisions that regulations must or may provide in relation to FCA rules providing for such fees, such as allowing fees to exceed the cost of the things in connection with which the fee is charged, and for the total amount of fees payable in connection with things to exceed the total cost. This subsection also enables the FCA to make provision about the treatment of amounts paid as fees to the persons listed in subsection (7).
	Subsection (10) mirrors sections under subsections (9) to (11) of section 11 in enabling FCA rules to specify whether – otherwise than in reliance on FCA rules – certain persons may or may not require payment in relation to activities described in section 15(8).
	Subsection (11) provides examples of the avenues by which those persons might require payment other than in reliance on FCA interface rules (e.g. by relying on powers conferred by other legislation or powers arising under contracts entered into).
	Subsection (12) provides that regulations may provide that the FCA’s powers to make interface rules includes powers to do things described in section 21(1)(a) to (h), for example to make different provision in relation to different purposes or areas, or for particular cases, and that the restriction in relation to fees in section 21(3) does not apply.
	Subsection (13) provides relevant definitions.
