I have just bought a flat, three-story block of flats in Cambridge.
All of the internal doors are fire doors which I understand is a requirement. But all of them are fitted with a self-closing chain (see attached image).
Currently the property is a private dwelling (I occupy it). But in future I will likely rent it.
So my question: What are he UK requirements for internal doors in flats? Can someone point in the direction of the guide lines/requirements
