Hi Darren, you can start an NPPL SEP course, then at say 25-30 hours convert to a full PPL course if you wish. Discuss this with your training organisation first.
That way you only need to finish what you find is best for yourself. You may tailor your License to suit the type of flying, and which airplane you will be using (+buying.) after your PPL.
There is often the discussion of how few hours are needed to maintain currency after PPL. However in reality most people who do the PPL want to fly at least 30 or more hours per year.
