No, it's usually just a quick look to make sure you're taking care of the room and that it isn't smashed up or anything. Thinking about it, it's disgusting that they're allowed to "inspect" a room that you're paying to live in when you're a fully grown adult. If you do break anything, you pay for it at the end of the year anyway!
I had all sorts in my room, including an extra heater because ours were rubbish, a kettle.. and I just put them under my bed when an inspection was due and they genuinely didn't pay much attention to anything at all.
