Three fire engines and around 15 firefighters were called to a fire at a derelict pizza restaurant on Barry Parade in Dulwich.
A small part of a single-storey outbuilding was damaged by fire. There were no reports of any injuries.
Station Commander Mark Edwards, who was at the scene, said “Crews arrived to find a smoke logged property and worked quickly to bring the fire under control and confine it to a fuse board.
“There were no working smoke alarms in the property, so crews installed a smoke alarm before leaving.”
The Brigade was called at 1720 and the fire was under control by 1855. Fire crews from Peckham, Forest Hill and New Cross fire stations attended the scene.
The Brigade’s fire investigators believe the fire was caused by a fault in an electricity meter.
