Nope, you can.
ANO para 157(c)...
for the purposes of Part 3 of this Order (other than articles 19(2) and 20(2)), if valuable consideration is given or promised for the primary purpose of conferring on a particular person the right to fly the aircraft on that flight (not being a single seat aircraft of which the maximum weight authorised does not exceed 910 kg) otherwise than under a hire-purchase or conditional sale agreement.
= If the aircraft is a single seater below 910kg it isn't considered public transport if hired, and therefore doesn't require a CofA.
The paragraph is I think there because of some robust negotiations by the Tiger Club years back which allow them to hire out their single seat Turbulents. It was used by the BMAA a few years ago as the precedent to allow them to negotiate hiring of 2-seat microlights with solo occupancy.
Not a lot of people know that!
What have you got and would I wish to hire them?
