Simtech Aviation have taken over the MCC business from Parc Aviation, they now do their MCC in an ATR simulator at their facility near Dublin Airport. Did my MCC with them last year, great bunch of instructors and good contacts within the airline industry.
There is also another company in Dublin called Pathfinders Aviation who carry out their MCC in a 737-200 Sim. I know some guys who did their MCCs there and have good things to say about them.
I reckon you should get in touch with Simtech or Pathfinders and get all the information you need. Best of luck!
