A mother and her two infants escaped from a blaze which ripped through their Harlesden home after being alerted of the danger by a smoke alarm.
The smoke alarm sounded giving the family of three enough time to flee from the fire which tore through the ground floor of the terraced house in Alric Avenue.
The trio left the house before the fire brigade arrived and were swiftly taken to hospital by London Ambulance Service suffering from smoke inhalation.
A London Fire Brigade spokespman said: “The smoke alarm has without doubt helped saved the life of the woman and her two children.
“It is vitally important that everyone has at least one smoke alarm on every level of their home and test it regularly as it gives you early warning of a fire in your home.”
The Brigade was called at 5.58pm and the fire was under control by 7.01pm.
21 firefighters and officers attended the scene with engines from Acton, Park Royal, Wembley and West Hampstead fire stations present.
The cause of the fire is under investigation.
