Four fire engines and around 25 firefighters were called to a small fire at a block of flats on Knightsbridge.
Part of the lift and some external cabling were damaged by the fire. Four residents and four members of staff left the building. There were no reports of any injuries.
The fire started in an electrical panel within the lift and the Brigade's fire investigators believe the fire was caused by the overloading of electrical wiring for the heaters in the lift.
The Brigade was called at 1317 and the fire was under control by 1407. Fire crews from Kensington, Soho and Fulham fire stations were at the scene.
