Four fire engines and around 25 firefighters responded to a fire on Barking Road, East Ham.
The fire occurred in an end of terraced house, consisting of two floors, which had been converted into flats. A first floor flat and loft space were damaged by the fire. Six people left the property before the Brigade arrived and there are no reports of any injuries.
The Brigade was first called about the incident at 1652, and crews from East Ham, Barking and Plaistow fire stations attended the scene. Crews had the fire under control by 1739.
The fire is believed to have been accidental, caused by an electrical fault in wiring.
