A ban here is recognised as a ban in the Republic of Ireland, Northern Ireland and the Isle of Man. It is called a reciprocal agreement, and all those countries regognise our ban as well.
As to elsewhere in the he world, no you are not disqualified, but you need to be the legal holder of a U.K. licence to drive in other countries as a visitor, and of course if you are banned here then you do not have a valid licence to use abroad.....
