A man and a woman had a lucky escape following a fire at a bungalow on the Peabody Estate on Fulham Palace Road in Hammersmith.
Four fire engines and around 25 firefighters dealt with the blaze which damaged part of the roof of the bungalow. The smoke alarm sounded and the man and woman both left the property before the Brigade arrived.
A spokesperson for the London Fire Brigade said: "The occupier was alerted to the fire by smoke alarms. It’s incidents like these that show how important it is to have working smoke alarms and regularly test them.
“This incident shows just how important it is to have working smoke alarms fitted throughout your home.
“Smoke alarms give the earliest possible warning when a fire starts and we would urge everyone to make sure they have one fitted in every room where a fire can start except kitchens or bathrooms where heat alarms are more appropriate.”
The Brigade was called at 0403 and was under control by 0506. Fire crews from Hammersmith, Fulham and Kensington fire stations attended the incident.
The cause of the fire is believed to be due to an electrical fault.
