Four fire engines and around 25 firefighters tackled a fire at a shop with dwellings above on Queensway in Orpington.
A small part of the ground floor was damaged by the fire. One man left the building before the Brigade arrived. There were no reports of any injuries.
The fire is believed to have been accidental and was caused by the self-heating of textiles.
Control Officers took the first of three calls at 1916 and mobilised crews from Orpington, Sidcup, Bromley and Beckenham fire stations to the scene. The incident was over for firefighters at 2113.
