Firefighters have issued a reminder of their smoking safety advice following a fire at a mixed-use building on Eden Street in Kingston upon Thames.
Half of the second floor was damaged by the fire. There were no reports of any injuries.
The fire is believed to have been accidental and caused by the unsafe disposal of smoking materials.
A London Fire Brigade spokesperson said: "If you smoke it is vitally important you stub it right out, preferably in an ashtray.
"Always 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. Firefighters recommend that you have a look at our online Home Fire Safety Checker to make sure there are no hidden hazards in your home.
"The online tool will ask you a series of questions that will help us work out the level of risk in your home, or the home of someone you care for. It only takes a few minutes to get tailored advice to keep yourself and loved ones safe from fire."
The Brigade was called at 2333 and the incident was over for firefighters at 0013. Crews from Surbiton, Kingston, New Malden and Twickenham Fire Stations attended the scene.
