Firefighters have issued a smoking safety reminder after rescuing a man from a flat fire on Flaxley Road in Morden.
Part of a converted three-roomed flat on the ground floor of the building was damaged by fire. Firefighters rescued a man from a ground floor window who was treated on scene.
The fire is believed to have been accidental and caused by smoking materials.
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 your home but also cost you your life."
The Brigade was called at 0651 and the fire was under control by 0710. Three fire engines and around 15 firefighters from Sutton and Wimbledon fire stations attended the scene.
