A stray firework is believed to have caused a fire at a mid-terraced house in Pain’s Close, Mitcham.
Two fire engines and 10 firefighters and officers were called to the blaze which started in the garden of the property.
The kitchen was destroyed after the fire spread from the garden to the window of the house. A bedroom on the first floor also sustained some damage.
One person was treated at the scene for smoke inhalation by London Ambulance Service crews but was not taken to hospital.
The Brigade was called at 1928 and the fire was under control at 2022. Fire crews from Norbury and Mitcham fire stations attended the scene.
The cause of the fire was accidental due to a lit firework landing amongst items stored in the garden.
Always follow the Brigade's bonfire and firework safety advice, including:
• Only buy fireworks marked with the British Standard Kitemark BS7114
• Don't drink alcohol if setting off fireworks
• Keep fireworks in a closed box and always follow the instructions carefully when using them
• Light them at arms length using a taper and stand well back
• Never go back to them once they are lit. Even if a firework hasn't gone off, it could still explode
• Never throw fireworks and never put them in your pocket
• Respect your neighbours – don’t let off fireworks late at night and remember there are laws to follow
• Take care with sparklers – never give them to children under five. Even when they have gone out they are still hot so put sparklers in a bucket of water after use
• Keep your pets indoors throughout the evening
