JAR-FCL 1.355 states that if you don't meet the experience requirements (which have changed by the way, now 50/15) then you must attend an FI Seminar and sucessfully undergo the proficiency flight with an FIE.
Your first renewal and every other one thereafter must contain the proficiency/FIE option.
Sometimes the national authority will not run or sponsor seminars that frequently... you may need to plan WELL ahead if you want to stay flying.
