I don't know about the EU, but in the US you wouldn't get your approach clearance from the tower, you'd get it from approach control. In a non-radar environment, you'd typically do the hold once, unless approach tells you not to. They would hand you off to the tower after they give you the approach clearance. I should add that there are relatively few areas in the US where there are airports big enough to have an ILS yet remote enough to be outside of radar coverage, so it's not a common problem.
