LASORS Section E 1.2 reads:
Holders of an ICAO SE IR(A) wishing to obtain a JAR-FCL ME IR(A) will be required to attend an approved IR(A) training provider. There are currently 3 alternative approved courses of training to obtain the JAR-FCL ME IR(A). Applicants should consult with the IR training provider as to which course of training they have been approved to conduct. In addition they shall either hold a multi-engine type/class rating, or have at least completed an approved course of training for the ME class rating. The 3
options are:-
Option 1: Complete a minimum of 15 hours SE IR flight instruction, of which 5 hours may be in a FNPTI or 10 hours in a FNPT II or Flight Simulator. In addition, applicants must hold a multi-engine class rating and complete an additional 5 hours instrument flying instruction in multi-engine aeroplanes, of which 3 hours may be in a Flight Simulator or FNPT II and pass a ME IR(A) Skill Test; or
Option 2: Complete a minimum of 13 hours ME IR flight instruction in a ME FNPT II. In addition, applicants must hold a multi-engine class rating and complete at least 7 hours instrument flying instruction in multi-engine aeroplanes; or
Option 3: Complete a minimum of 15 hours ME IR instruction in a multi-engine aeroplane (no instructional time will be allowed in a FNPT or Flight Simulator).
I would personally recommend option 2.
