Firefighters have issued a reminder of their smoking safety advice following a fire at an end of terraced house on Fulwell Road in Teddington.
Most of the loft conversion was damaged by the fire. One man left the building before the Brigade arrived and was treated on scene by London Ambulance Service crews.
The fire is believed to have been accidental and was caused by the unsafe disposal of smoking materials.
A London Fire Brigade spokesperson said: "If you're 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.
“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.”
One of the Brigade's 32-metre turntable ladders was used at the scene as an observation tower.
The Brigade was called at 1400 and the fire was under control by 1602. Eight fire engines and around 60 firefighters from Richmond, Heston, Kingston and surrounding fire stations attended the scene.
