NRC is right. The last thing you need is somebody visiting your home with a warrant. There must be a Garda presence when the warrant is produced. If the visit leads to prosecution, the expense of the issue of the warrant, Garda presence, extra TV Licence Inspector attendance etc may be relevant in the amount of the possible fine.
Remember it is just a TV Licence issue nothing more. There are people who for whatever reason protest by not buying a TV licence. They get their day in court and are usually fined more than Joe Soap who merely played TV licence roulette and lost.
My advice to anybody in JullyB's situation is to just get a TV licence - You're worth it!
