Firefighters are warning of the dangers of leaving cooking unattended after a fire at a house on Pinecroft in Romford.
Most of the ground floor of a semi-detached house was damaged by fire. Five people left the building before the Brigade arrived. One man, one woman and three children were treated on scene by London Ambulance Service crews.
The Brigade's Fire Investigators believe the fire was caused by a chip pan which was left unattended.
A London Fire Brigade spokesperson said: ""Fires are more likely to start in the kitchen than any other room in the home.
"Cooking should never be left unattended on the hob or grill - if you have to leave the kitchen, turn off the heat.
"Chip pans and cooking with hot oil can be really dangerous and the risk increases when you start frying food more than once.
“All it can take is for you to become distracted for a few seconds and your cooking oil can quickly go up in flames.”
The Brigade was called at 2110 and the fire was under control by 2201. Four fire engines and around 25 firefighters from Hornchurch, Harold Hill, Dagenham and Romford fire stations attended the scene.
