Fire Doors in Converted 2 bedroom 1st floor flat with private entrance and no communal areas.

[Guest Jane Smith]

Do I need fire doors in my converted 2 bedroom 1st floor flat if I decide to let it out.    It was converted in 1950's from a house that was built in 1925. There are no communal areas and it has it's own private front door.

No. The primary requirements are smoke alarms and if gas/solid fuel/oil appliances (other than cookers) are Carbon Monoxide alarms
