Of the 3 major offshore companies in the UK, only Bristow will accept a SE IR; CHC and Bond both require a ME IR to even consider you.
Actually in the last 6 months CHC in Aberdeen have employed 3 new FOs with SE IR(H). Incidently these were all completed at Billund Air Center in Denmark.
Having also completed this course and been subsequently employed by CHC in 2010 I can highly recommend this route. I reckon I saved myself in the order of £15k which is hardly to be sniffed at and the BAC course was excellent (don't believe a word from anyone who tells you it's not as worthy as a ME IR, the skills learned are very easily transferred into a big twin.)
