Four fire engines and around 25 firefighters were called to a fire at a beauty salon on St John’s Hill in Clapham Junction.
Part of the ground floor of a beauty salon with flats above was damaged by fire. Three people left the building before the Brigade arrived. There were no reports of any injuries.
Residents in the flats above were alerted to the fire when they heard smoke alarms sounding. They then called 999.
A London Fire Brigade spokesperson said: “This incident shows just how important it is to have working smoke alarms.
“Smoke alarms give the earliest possible warning when a fire starts, providing time to escape. We encourage everyone to have smoke alarms fitted in every room where a fire could start, plus a heat alarm in the kitchen. It's important to test them regularly.”
The Brigade was called at 2037 and the fire was under control by 2206. Fire crews from Battersea, Wandsworth, Clapham and Chelsea fire stations attended the scene.
The fire is believed to have been caused by an electrical fault in a nail lamp.
