Two men were given vital fire survival guidance by 999 control officers before being rescued from a house fire in Reading Road, Northolt.
A neighbour of the terraced property raised the alarm and two fire engines and around ten firefighters from nearby Northolt Station attended the incident.
The men who were on the first floor of the property also called 999 and were given advice about how to stay safe in the property while they waited for firefighters to arrive.
Crews wearing breathing apparatus led one man to safety from the first floor and crews rescued another man from a flat roof at the rear of the property using a ladder. They were both taken to hospital by London Ambulance Service.
Sub Officer Ricky Matthews, who was at the scene, said: “Crews arrived at the scene very soon after the initial 999 call and quickly got to work getting the fire under control and rescuing the men who were trapped inside.”
He also praised the quick actions of the next door neighbour who, as well as calling 999, ran to the fire station to raise the alarm.
The Brigade was called at 0227. The fire was under control by 0339.
The cause of the fire is under investigation.
