I used to live in a flat (I guess you would call it a condo in the US) with heating provided by the building. My landlord who I lived with left the heating on 24/7 during the winter and the flat would get ridiculously hot. Even though he was the one paying for it indirectly through service charges. This arrangement is becoming quite common for new build flats in the UK but I would actively avoid if I was looking to buy.
