Sorry, I just don't follow you logic.
Why would you need a CPL to hire? You are paying the hirer for the use of the aircraft. To be caught by the aerial work regs surely the PIC would need to be the one that was
being paid or
receiving the valuable consideration.
if valuable consideration is given or promised for the carriage of passengers or cargo in the aircraft on that flight;
Costs can be shared by PIC/Pax on a private flight. I do not believe the payment for use of an aircraft does constitute aerial work.
Charity work is a stated exception subject to CAA clearance.
Thanks WR.
