I'm renting a modern terrace townhouse with 3 floors. All the internal doors have springs which make them shut on their own. I want to disconnect them to protect fingers etc but hear 2 separate versions of advice: Version 1 that Fire Regulations require spring doors in modern 3 floor properties and, Version 2 that Fire Regulations have been changed due to lobbying by the medical profession and spring doors are no longer required. Does anybody know or can anybody advise how I find out?
