Part of the ground floor, first floor, and roof of the building are alight, the London Fire Brigade revealed in a statement. The cause of the fire is not known at this stage.
Station Commander Paul Green, who is on the scene, said: “Firefighters are working hard to bring this significant blaze under control.
“Due to the nature of the business, there are a lot of materials including bed linen and towels inside which have caught alight.
“The fire is creating a lot of thick smoke so we would ask local residents to keep windows and doors closed.
“There are a number of local road closures in place, including Chigwell Road which has been shut from Southend Road and Maybank Road.”
