My comment
We also know that you can still add an IMC rating to a licence that looks like a JAR licence before it is converted.
I don't have a reference for - it came from someone else's forum post. The CAA don't have an answer to this or whether you will be able to add a new IR(r) to a Part-FCL licence before April 2014.
However, there is the interesting line in
CAP 804 Part I Part E 3.3.4 page 546:
IMC Ratings or privileges gained after 7 April 2014 are not convertible to restricted IR
on Part-FCL licences.
This suggests that you can add them before that date.
You will always be able to get an IMCR which would be put onto an additional non EASA UK licence but after April 2014 it would not be usable on EASA aircraft.
Clear as mud.
