A woman was rescued by firefighters after a fire at a flat in Pampisford Road, South Croydon.
Part of a ground floor flat was damaged by fire. Firefighters wearing breathing apparatus rescued a woman from the property and she was treated at the scene for smoke inhalation before taken to hospital by London Ambulance Service crews.
The property did not have any working smoking alarms.
A London Fire Brigade spokesperson said: “Homes need multiple and linked smoke alarms or you won’t be properly covered. Ideal spots for smoke alarms include rooms where you leave electrical equipment running like satellite boxes, computers or heaters; any room where you smoke, and anywhere you charge your mobile or laptop.
“As a minimum you should have smoke alarms on every floor - in the hallways and the rooms you use the most, plus a heat alarm in the kitchen. They should be linked together and tested regularly.”
The Brigade was called at 1355 and the fire was under control at 1431. Two fire engines from Croydon and Purley fire stations attended the scene.
The cause of the fire is under investigation by the Brigade and Metropolitan Police Service.
