The blue plaques scheme honours notable men and women in London who have lived or worked in the building. Outside the capital, the scheme is administered by the British Plaque Trust.
Margaret Lockwood moved to Upper Norwood as a child with her mother and brother in the 1920s, moving to a number of properties in the area.
The unveiling of an English Heritage blue plaque comes a little over three years after the Heritage Foundation unveiled a plaque to Lockwood at her former home in Kingston. You can watch my talk about Margaret Lockwood that I gave at the time.
The unveiling takes place from 11.45am on 21st November at 14 Highland Road, London, SE19 1DP. There will be a screening afterwards of The Lady Vanishes (1938) at the Everyman Cinema, Crystal Palace from 1.30pm.
