Four fire engines and around 25 firefighters were called to a fire at a public house and hotel on Royal Parade in Chislehurst.
A small part of an electrical intake room in the basement was damaged by fire. The fire alarm sounded which alerted people to the fire and round 150 staff and guests left the building before the Brigade arrive. There were no reports of any injuries.
The Brigade was called at 1747 and the fire was under control by 1857. Fire crews from Sidcup and Bromley fire stations attended the scene.
The cause of the fire is believed to be accidental and involved an electrical mains supply.
