Firefighters have issued another warning to smokers after a fire at the rear of a laundrette on Green Lanes in Hornsey.
Part of a lean-to was damaged by 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'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.
"With the dry weather conditions that London has been seeing and will continue to see, any fire can quickly get out of control. It only takes a small spark to ignite dry grass, shrubs, or litter and many grass and land fires are caused by discarded cigarettes and matches.
“Never throw cigarette ends out of car windows and if you are smoking on your balcony, have an ashtray to hand, and don’t flick your ashes off the balcony. “
The Brigade’s Control Officers were called at 0420 and mobilised crews from Hornsey, Holloway and Tottenham fire stations to the scene. The fire was under control by 0753.
