So to summerise from the information in this thread (for the Modular Route);
You will need 150hrs TT before you take the skill test. The amount of PIC time does not really matter if taking the skill test on SE aircraft. It would obviously be advantageous to have lots of P1 time, but not a pre-requisite for the skill test. If you are doing the CPL/ME then you must have 70hrs PIC.
For the application of the CPL you need 200hrs TT, 100hrs of which must be PIC.
