Emergency services were called to an apartment fire in Fulham after neighbours spotted smoke pouring from the property.
People living on Perham Road raised the alarm at 4.45pm on February 20. It later emerged the property was not fitted with smoke alarms.
Four fire engines and 21 crew attended the incident, which resulted in damage to the kitchen and living room.
A London Fire Brigade spokesperson said: “There were no smoke alarms in the flats or communal areas so it was lucky that the neighbour noticed the smoke and raised the alarm.
“Everyone should have at least one smoke alarm on every level of your home and the safest option is have those linked together. This will give the earliest warning if there is a fire in your home."
No-one was in the property or hurt.
Firefighters from Fulham, Hammersmith and Kensington fire stations attended the fire, which as under control at around 5.40pm.
Its cause is now under investigation.
