A founding student at Benton End who studied under Sir Cedric Morris and Lett-Haines at The East Anglian School of Painting and Drawing.
Warburton struck up a friendship with Lucien Freud which persisted when she moved to London with her husband.
Her work in oil reached a zenith after the war and during the 1950’s when she had multiple solo shows. Her London streetscapes and paintings of both cats and pigeons are especially coveted.
Later in life Warburton and her husband moved to Stoke-by-Nayland. Back problems stopped Warburton painting in oil but there followed a period of magnificent watercolours and works in pastel.
