Firefighters are issuing a smoking safety warning following a shop fire on Rye Lane in Peckham.
A small part of the rear of the shop and a yard containing mixed refuse were damaged by the fire.
The cause of the fire is believed to be accidental caused by a discarded cigarette.
A London Fire Brigade spokesperson said: "We'd rather you didn't smoke at all, but if you are a smoker, it's absolutely vital you ensure your cigarette is completely out when you've finished smoking it.
"If you don't, you risk causing a fire which could not only destroy properties but also cost you your life."
The Brigade was called at 1413 and the fire was under control at 1617. Fire crews from Old Kent Road, New Cross and Brixton fire stations were in attendance.
