Twelve fire engines and around 80 firefighters and officers dealt with a fire in the roof of the building on Long Acre in Covent Garden this afternoon.
Part of the mansard roof and two split level flats either side of the roof were damaged in the building consisting of shops with flats above it. One woman left the building before the Brigade arrived. She was treated for smoke inhalation by London Ambulance Service. Four other people were rescued from the building by fire crews wearing breathing apparatus.
Station Manager Gareth Cook was at the scene, he said: "The fire started in a flat on the top floor of the building. Crews worked hard to contain the fire and stop it spreading to an adjacent flat."
The Brigade was called at 1256 and it was under control by 1613. Crews from Lambeth, Euston, Soho, Dowgate, Shoreditch, Whitechapel and Chelsea and surrounding fire stations were at the scene.
The cause of the fire is believed to be accidental.
