You're not going to like this - but the following comments are truly designed to help you (and your colleagues) move in the right direction. Apologies if it sounds confrontational - it isn't meant to be.
I'm sure you didn't mean it that way - but your postings suggests (at least to me) that you might not believe the answers we give yoiu anyway.
Although you clearly haven't started the CPL course yet, one of the impotant factors of the end result of taking the skill test is that you suddenly become a "Professional Pilot". The CPL is a licence change - you move from Private Pilot to PROFESSIONAL pilot and are expected to know the rules and regulations as part of making that transistion - and there's abig push by the CAA to see that this happens.
If you have done the groundschool and exams already - you should know where to find the answer for yourself. If you haven't yet taken the exams then PLEASE do so before doing the hour building, sky drilling, phase of your modular course. Don't do the fun stuff first and then have all the hard work to do whilst getting rusty with your flying skills whilst studying the books.
The question you ask is about JAA pilot licensing - albeit about the course and requirements to achieve that licene - so the answer is in JAR FCL.
I'm working on a remote computer at the moment, so cannot help you by posting the link - no doubt somebody else will do it for you shortly.
The answer to your question - the only pre-course requirement is a total time of 150 hours. By the end of the course you must have at least 175 hours, a night qualification and an R/T licence.
BY the time you APPLY FOR YOUR CPL you must have at least 200 hours total time - which must include 100 hours of P1 including the "long cross country".
Really hope I didn't come over too "angry" - just trying to point you towards how to find the answer.
Now, I'll get round to pressing "submit" and see if anybody else has answered during all the time it's taken me to write all this.
All the best with the training.
