Five people fled a fire at The Kennington pub in Camberwell New Road this morning.
London Fire Brigade received nearly a dozen calls from 8.25am after the blaze broke out on the third floor of the building, which also contains flats.
The room where the fire started was completely destroyed but, fortunately, there were no reports of any injuries.
The fire was under control by 9.30am thanks to 25 firefighters from Lambeth, Peckham and Brixton stations.
The cause is now under investigation.
