Valid 2 years
The only CAA currency requirement is for 3 take-offs and landings within 90 days to carry passengers. Clubs will probably impose their own currency requirements which will be more strict.
To remain current at the 2 year point:
12 hours in the last 12 months (plus 12 T/Os and Landings) + a 1hr flight with instructor. Once you have achieved this you need to present your logbook to an examiner or an instructor with FCL945 privelages who will sign your licence and complete CAA form SRG1119E. If you forget to do this and you pass the 2 year point then your effort has been wasted and you will require a proficiency check. Signatures can not be back-dated.
Proficiency check. This is a pass/fail test and the profile is at the discretion of the examiner but you should expect some navigation, steep turns, stalls, PFL, ccts.
