Firefighters are reminding people about the importance of having working smoke alarms after they alerted a family to a fire in their home in Manor Park.
A small fire broke out in the bathroom of the house in Woodhouse Grove and the occupants of the property were woken up by the sound of the smoke alarm in their hallway.
The two adults and two children who left the property before firefighters arrived and were treated at the scene for smoke inhalation by London Ambulance Service crews.
A London Fire Brigade spokesperson said: “This incident is timely reminder about the importance of having smoke alarms in your home. In this case, the residents were asleep and were alerted to a small fire in the bathroom by their smoke alarm and they immediately called 999 and left the property.
“Homes need multiple smoke alarms or you won't be properly covered. As a minimum, you should have smoke alarms on every floor of your home - in the hallways and the rooms you use the most plus a heat alarm in the bathroom and kitchen."
A small part of the first floor was damaged by fire.
The Brigade was called at 0250 and the fire was under control at 0321. Two fire engines and around 10 firefighters from East Ham and Stratford fire stations attended the scene.
The cause of the fire is believed to be accidental and due to an electrical fault.
