Residents in Chiswick heard screams coming from the flat of a disabled woman, as the property was engulfed in flames.
Neighbour Toni Simonovski was among those who tried to save her, carrying her out of the flat.
Paramedics spent over an hour trying to revive the victim, but it's thought she had been overcome by fumes. She was pronounced dead at the scene.
Toni Simonovski talks to reporter Phil Bayles.
