Hi - wait til you have passed your ME/IR before sending your paperwork for licence issue, since the IR issue is free of charge if it's made at the same time as the CPL issue (just as the IMC issue was free of charge if done simultaneously with the PPL issue). The CPL issue was £167 in December, but you'd better check with Cash And Agro themselves in case their fees have gone up (yet again).
MCC - they don't really want to hear about it until you have to "unfreeze" (i.e. issue) your ATPL.
Cheers.
