Flying hours requirement: For the licence you must complete a minimum of 40 flying hours including dual flights with an instructor solo flights cross country solo flights and some instrument flying.
Ground modules & exams: Alongside flying you'll complete several theoretical modules (like Air Regulations Air Navigation Meteorology Technical General Technical Specific Radio Telephony) and pass written exams.

If there are delays holidays weather disruptions or you have to fly less often it could stretch closer to 12 months or even more.
