The cost of a licence depends on your life experience [age!] and the frequency of lessons.   The minimum requirement for a microlight licence is 25 hours of which 10 hours must be solo.   Funny isn’t it? In a car a Learner must have someone with them all the time but in an aircraft one must prove one can fly by being by yourself! A light aircraft licence is 34 hours or more with a similar syllabus so a rough idea of the cost of a licence would be 34 x £110 = £3740 probably taking two seasons.   A pre-payment of 10 hours or more qualifies you for an 8% discount at flights-with-rosie.
