Firefighters are encouraging people to install smoke alarms after saving a family from a blaze which "could have been a lot worse" if no-one had been home.

Ten fire officers from Mitcham and Wimbledon fire stations were called to a house near the Baitul Futuh Mosque in Morden at about 10.30pm last night.

A Mitcham fire officer who attended the fire in Rosedene Avenue said it was caused by a wiring fault in a dimmer switch which started burning.

He said firefighters were able to extinguish the kitchen fire in just a few minutes, limiting damage to the property.

But he noted the property did not have a smoke alarm and said it could have been far more serious if no-one had been at home to notice the fire.

No-one was injured.
