Four fire engines and around 25 firefighters were called to a fire at a restaurant with flats above in Kenway Road in Earls Court.
The restaurant's ducting (ventilation system) from ground to second floor level was destroyed by fire. Around 30 people left the restaurant and 10 residents left the flats above before the arrival of the Brigade. There were no reports of any injuries.
The Brigade's fire investigators believe the fire was accidental caused by the build up of grease inside the ducting system being ignited by the heat of the charcoal grill below.
A London Fire Brigade spokesperson said: "Restaurant and take-away owners should always take care to make sure their extraction systems are kept clean as a build up of fat and grease within the filters can lead to a fire.”
The Brigade was called at 2014 and the fire was under control at 2154. Fire crews from Kensington, Fulham, Paddington and Chelsea fire stations attended the scene.
