What is EMA?
If I was planning to fly down somebody's ILS and then break off, I would call them to ask if they don't mind. I think in most cases it is OK, and same for most other places in Europe.
If anything, they may want your credit card details so they can charge for it
Some places also offer a low level letdown (or whatever they call it). I used to get this from Shawbury when going to Welshpool. Shawbury has an ILS but they were not keen on it being used for this purpose, but they do a letdown down to about 1400ft QNH, IIRC.
Otherwise, you do a DIY letdown
The safe way is to do it offshore, but that's not a useful option for say Welshpool
