Four fire engines and around 25 firefighters responded to a fire in a public house on Bramley Road, Kensington and Chelsea.
The building consisted of three floors and a basement. A section of the basement was damaged by the fire. Four people left the property before the Brigade arrived.
The Brigade received the first of two calls reporting the fire at 1204, and crews had the incident under control by 1247. Crews from North Kensington, Kensington and Paddington fire stations attended the scene.
The fire is believed to have been accidental, caused by the unsafe disposal of smoking materials.
