Four fire engines and around 25 firefighters tackled a fire at a public house on Elgin Avenue in Maida Vale.
A small part of the basement was damaged by the fire. 11 people left the building before the Brigade arrived. There are no reports of any injuries.
The fire is believed to have been accidental and caused by the self-heating of textiles.
A London Fire Brigade spokesperson said: "These types of fires often involve textiles that become contaminated with oil, most commonly linseed, massage and cooking oil on tea towels, tablecloths and chef whites. Make sure you check the manufacturer's cleaning recommendations of your textiles before washing.
"Sometimes when materials are cleaned and put in tumble dryers, the heat from the tumble drying cannot escape. This can result in a high enough temperature allowing it to build up to a point where it smoulders and eventually ignites.
“If you are washing and then drying on a hot cycle, always use the cooling cycle on the tumble dryer so it cools down and allow the heat to dissipate properly, before stacking laundered items together.”
Control Officers received the call at 1632 and mobilised crews from Paddington, West Hampstead and North Kensington fire stations to the scene. The incident was over for firefighters at 1811.
