Two men were taken to hospital and a man had to be rescued from a fourth-floor bedroom after a fire broke out at a maisonette.
Part of the second floor of the split-level maisonette in Market Place, Bermondsey, was damaged by the fire.
The fire brigade was called at around 7am yesterday and the fire was under control by around 8.30am.
Three fire engines and about 15 firefighters from Dockhead, Old Kent Road and Deptford fire stations attended the scene.
Crews wearing breathing apparatus rescued the man from the fourth floor by giving him a fire escape hood.
Fire escape hoods provide up to 15 minutes’ protection from four of the fumes which can prove fatal – carbon monoxide, hydrogen cyanide, hydrogen chloride and acrolein.
They do not provide oxygen but temporarily filter toxic smoke to make breathing easier.
The cause of the fire is under investigation by the brigade and the Metropolitan Police Service.
