This terrifying demonstration shows just how quickly a Christmas tree fire sparked by fairy lights could ravage your home.
London Fire Brigade tweeted a video of the controlled blaze, which spreads through an entire room after starting just 30 seconds before.
The first sparks are seen just 10 seconds into the clip, with the fire spreading quickly through the tree.
Seconds later smoke is billowing from the tree as the fire rages, spreading to the ceiling.
In the video’s final moments, the whole tree is melting as the blaze dominates the room.
The fire is sparked inside the tree, which it quickly engulfs before spreading through the room in the demonstration
The London Fire Brigade Tweeted: ‘A house fire, most likely sparked by faulty Christmas tree lights, envelopes a living room.
‘Check your Christmas tree lights are in good condition & turn them off before you go to bed. Make sure you have working smoke alarms.’

The video was shared to warn of the danger that can occur from faulty lights and overloaded plug sockets.
Battery-powered fairy lights are an easily accessible alternative that rule out danger from overloaded sockets.
Latest figures from the government’s Fire Kills campaign revealed 264 people died in fires in the home in 2015.
In the year ending June 2017, more than 200 died as a result of dwelling fires in the UK, according to Fire and Rescue incident statistics.

Statistics show you are seven times more likely to die in a home fire if the property lacks working smoke alarms.
People are advised to consider the danger posed by dry trees, electrical decorations and wrapped presents, all of which can fuel fires.
Anybody using fairy lights should take care to switch them off before they go to sleep.
