The fire brigade are battling a large fire in Crayford this evening at four homes.
Eight fire engines and 60 firefighters are on scene.
Fire has spread along the roof at the site on Crayford Way.
Station Commander David Reed said: “The roof spanning across four terraced houses is completely alight.
“One of the Brigade’s 32-metre turntable ladders is being used as a water tower at the scene to get water on the building externally.
“Crayford Way is closed between Thames Road and Mill Place whilst crews work to make the scene safe and people are urged to avoid the area due to heavy congestion.
“We know it’s a warm day, but the fire is producing a lot of smoke in the local area, so we’re advising residents to keep their windows and doors closed.
“There are currently no reports of any injuries.”
