Six fire engines and around 40 firefighters dealt with a house fire on Kennington Road in Lambeth.
The third floor and the roof was badly damaged by the blaze.
The cause of the fire is accidental and most likely caused by a candle left unattended.
Firefighters' candle safety top tips
- Make sure you put out any candles, incense and oil burners when you leave the room and especially before bed.
- Place candles, incense and oil burners in heat-resistant holders and placed on a stable surface where they won't be knocked over.
- Keep them away from materials that might catch fire - that's things like curtains, furniture, clothes and hair.
- Be aware that tea lights get very hot and without proper holders can melt through plastic surfaces like a TV or bath.
- Led candles can be a great alternative - they're safe even if you fall asleep or forget to blow them out.
The Brigade was called at 1815 and the fire was under control by 2038. Fire crews from Lambeth, Dowgate and Soho fire stations were at the scene.
