Student Accomodation always has locks on the inside of the doors
Private Accomodation can vary. I dont think I have locks on my next accomodation, so I am buying various locking features which includes kensington locks for my equipment, bike locks and lockable money boxes for storing important pieces of info.
Its not the best situation to be in, especially as I do not know some people in the flat, but I am hoping that my insurance and several common sense security approaches work.
If you have a separate contract and/or lockable doors you have to get a TV Licence. If you have a joint tenancy and no locked doors, then there is no problem. I am in flat this year with just one common room, but if you are in a house with a living room, etc then you could get a TV licence for the communal areas.
