I don't know about ACA
But ACS is available at any Prometric testing centre, which you must have some of in Ireland (NI or Eire?)
ACE, you have to travel to Avaya for (so USA or Welwyn) I'd guess

I have always wished that my computer would be as easy to use as my telephone.
My wish has come true. I no longer know how to use my telephone.
