Four fire engines and around 25 firefighters were called to a house fire on Rochester Road in Hornchurch.
Part of the ground floor and part of the fascia of an end-of-terrace house was damaged by fire. A conservatory at the rear of the property was destroyed by the blaze. Four people left the building before the Brigade arrived. There were no reports of any injuries.
The Brigade’s 999 Control Officers took 25 calls to the fire.
The fire is believed to have been caused by wind blowing flames from a barbecue into a house.
A London Fire Brigade spokesperson said: “On arrival crews were faced with flames spreading inside the house and up the external side of the building from the barbecue in the garden.
“If you’re having a barbecue, it’s vital that you place them on level ground, far away from anything that could catch fire, like sheds, fences or trees and out of the reach of children or pets. Make sure you keep them outdoors and never barbecue on a balcony.
The Brigade was called at 1804 and the fire was under control by 1853. Fire crews from Hornchurch, Dagenham, Wennington and Romford fire stations attended the scene.
