Four fire engines and around 25 firefighters tackled a fire at a sports club house on Oxford Road in Sidcup.
The single storey building was partially damaged by fire. Five gas cylinders at the scene were cooled to an ambient temperature and removed, as some cylinders can explode when exposed to heat. There were no injuries.
The Brigade was called at 0332 and the fire was under control by 0507. Crews from Sidcup, Eltham and Orpington fire stations attended the scene.
The cause of the fire is under investigation.
