Firefighters have issued a reminder of their candle safety advice following a fire at a block of flats on Allitsen Road in St John's Wood.
Half of a ground floor three-roomed flat was damaged by the fire. One man left the building before the Brigade's arrival.
The fire is believed to have been accidental and caused by a candle.
A London Fire Brigade spokesperson said: “Fires can cause devastation all year round, but this is heightened around Christmas with families potentially left homeless and possessions destroyed. We want to ensure Londoners take every precaution to prevent fires from spoiling the festive period.
“Keep candles well away from any Christmas decorations. Decorations can easily fuel a fire and as Christmas trees dry out, they can burn quickly and cause flames to spread in seconds.
“Consider using battery-powered, flameless LED candles instead, which are safe even if you fall asleep. Whilst they may cost more upfront than traditional candles, they will last considerably longer, giving you better value for money.
“If you do choose to use traditional candles ensure you place them in a heat-resistant holder, on a stable surface where they won’t be knocked over and away from materials that could catch fire. Never leave them unattended around your home, take particular care with children and pets and blow them out properly before you go to bed.
“Whether you’re spending Christmas at home, or away with friends or family, take some time to carry out a few simple checks to keep yourself and your loved ones safe.
“The Brigade’s online Home Fire Safety Checker can guide you around your home and provide you with specific advice to reduce fire risks.”
The Brigade was called at 1835 and the incident was over for firefighters by 1926. Four fire engines and around 25 firefighters from Paddington, Euston and West Hampstead fire stations attended the scene.
