"any reward paid to a Ltd Co or umbrella co which then pays the FI. As long as the FI does not own the company they are not taking reward for the flight Instruction."
Hmmmmm..........so what's he being paid for then, bose ?
Surely it doesn't matter whether it's the FTO or the Limited Company that pays him/her. He/she is still being paid for instructional services rendered as far as the CAA is concerned.
