English Heritage curatorial director, Matt Thompson, said: "2025 marks an exciting year for the Blue Plaques Scheme as we honour these outstanding individuals who transformed the cultural fabric of London.
Hepburn's plaque will go up in Mayfair, a high-end neighbourhood of London where the actress landed her Oscar-winning role as Princess Anne in 1953 romance film Roman Holiday, starring alongside Gregory Peck.
T Rex frontman Bolan will be marked with a plaque at one of his west London addresses, while English National Ballet co-founder Markova is set to be honoured at her childhood home in Muswell Hill.
The location for a plaque commemorating Jamaican writer Marson, claimed by the BBC to be its first black producer on the payroll who would go on to develop Caribbean Voices, part of the Calling The West Indies series, is yet to be chosen.
Audrey Hepburn and glam rock musician Marc Bolan are among the stars being honoured with blue plaques celebrating their "profound impact".
