Firefighters rescued a man from a house fire on Addington Drive in North Finchley.
Part of the ground floor of a semi-detached house was damaged by fire. One man was taken to hospital.
The Brigade’s Fire Investigators believe the fire was accidental and caused by cooking left unattended.
Station Commander Neil Guyett, who was at the scene, said: “Firefighters wearing breathing apparatus rescued a man from the ground floor living room.
“Crews worked quickly to confine the fire to the kitchen and prevent further damage to the house.
“Fires are more likely to start in the kitchen than any other room in the home, so it's important to take extra care and never leave cooking unattended on the hob or grill. If you have to leave the kitchen, turn off the heat.”
The Brigade was called at 1737 and the fire was under control by 1815. Three fire engines and around 15 firefighters from Finchley and Hendon fire stations attended the scene.
