Is this what you you mean?
JAA Licences
If you have a JAA-PPL, do not confuse the expiry dates of the licence and the rating, JAA licences are valid for 5 years and the rating that is usually added, the SEP(L) is valid for 2 years. If the licence has expired then so long as it is expired by less than 5 years all that is needed is a valid medical (EASA class 2 or better) then reapply to the CAA to renew it.
