Four fire engines and around 25 firefighters tackled a fire at a block of flats on Hanson Street in Soho.
Part of a three roomed flat was damaged by the fire. Around 25 people left the building before the Brigade arrived. One man was rescued from the building by firefighters wearing breathing apparatus and taken to hospital by London Ambulance Service.
The fire is believed to have been accidental and caused by a halogen lamp.
A London Fire Brigade spokesperson said: "Lightbulbs can get incredibly hot and can set fire to combustible materials.
"It's important to keep them away from anything that might catch fire such as books, clothing, sheets and curtains.”

The Brigade was called at 2229 and the incident was over for firefighters at 2330. Crews from Soho, Islington and Lambeth fire stations attended the scene.
