Will I need a fire escape for my dormer loft conversion?
The dormer window serves as an escape route in times of emergency including fire emergency. Smoke alarms are required for every level of the house, including the loft. They must have a backup battery and wired to the mains in case of a power failure. There must be a protected area from your loft to the ground floor to ensure the occupants evacuated safely.
The fire route has to be protected to withstand 30 minutes of fire. The loft conversion should be complete with a functioning window with non-locking fasteners to ensure a swift exit.
