Can TV Licence inspectors check your bedroom?

I received a letter recently saying that a TV licence was not registered for the apartment in which I live. I share an apartment with two other people.

We have no television in our living room, nor are we set up for Saorview, Sky or any of those things.

However, I am wondering, if a TV licence inspector calls around, are they allowed to check your bedroom?

Leaving aside whether or not any of us have a television any of our rooms, it does seem to be rather an invasion of privacy to ask to see someone's bedroom.

If a TV licence inspector called round, would I have the right to refuse him/her access to my bedroom?
