Quite clearly the above suggests that ME IR (H) is type specific and therefore a TRI (H) instructing on ME Helicopter type may extend your SE IR to a ME IR.
@ Jet Ranger: you need to get your IR SE (A) converted to a IR SE (H)
Check out JAR–FCL 2.205 Flight instruction
(See Appendix 1 to JAR– FCL 2.205)
An applicant for an IR(H) shall have participated in a course of integrated flying training which includes training for the IR(H) (see JAR–FCL 2.165) or shall have completed an approved modular flying training course as set out in Appendix 1 to JAR–FCL 2.205.
If the applicant is the holder of an IR(A) the total amount of flight instruction required by Appendix 1 to JAR–FCL 2.205 may be reduced to 10 hours.
Once you complete the conversion from A to H then do your 5 hours dual instruction with the TRI/TRE for the B212 in order to extend your SE IR (H) to ME IR (H). And last but not least, if no TRTO offers to conduct the latter or the UK CAA rejects it, I suggest you go check out other JARland members
