Hello,i need some advice please. Today my landlord sent letters to each flat saying communal windows in the hallways cannot be opened if the temperature is below 18°c,its raining,snowing,hail or excess wind. No one lives in the communal areas,we all live in our flats. They even installed thermometers on each landing. Sometimes the communal areas stink & when they are cleaned,how can the floors dry if the windows arent open. Plus gov says open windows because of the virus. Can a landlord enforce this? Is this legal?? Thanks in advance.
