There is NO p1 requirement to start a CPL. There is a 150 hour total time requirement to start the CPL Flight training course. There is a 100 hour P1 time and 200 hours total time (no sim included in either number) for licence issue. A Night qualification is also required for licence issue for a CPL.
The 70 hours noted above is because that school does MEP/IR before CPL. To start an MEP Land class rating course you must have 70 hours PIC.
