I'm an owner-occupier. Some of the internal doors in my flat need replacing. I'm wondering whether to replace them with fire doors or non-fire doors - the latter would obviously be cheaper.
At the moment I have no plans to move out and let my flat, but it would be good to know that if I ever wanted to do that, I wouldn't need to change the doors! So it would be good to know whether internal doors in a rental property need to be fire doors.
(Obviously the front door of my flat, which opens onto the communal staircase, is a fire door.)
