Depending where you live really. Normally within a two mile radius it is €5 or €6. Another few miles it goes up to a tenner. But it is different strokes for different folks and again if you are in Dublin or a major city, then the prices may increase substantially. Don't believe there is a set charge for hackneys although they try to be more competitive than their taxi counterparts. I tend to use them more often because I know exactly what they will charge which is not the case with taxis whose charges seem to vary quite considerably.
