JWS - from the FPP website:
If you have completed, or are planning to complete, any JAR-FCL Airline Transport Pilot ground school examinations (or EASA equivalents) then you should note that in order to be accepted onto the Future Pilot Programme you must not have already sat any of these exams at the point of commencing training under this programme.
and
you must not hold a Commercial Pilot’s Licence or higher, or have commenced an integrated course of flight training, if you wish to apply for the programme.
No mention of ratings, so long as it's not a CPL.
