Waddington Custot was formed through the partnership of long-time London art dealer, Leslie Waddington, and French art dealer Stephane Custot in 2011. Located in Cork Street since 1958, formerly as Waddington Galleries, the gallery has a rich heritage and an international reputation for quality and expertise.

The gallery would become instrumental in the promotion of post-war American art in England, showing the influential work of Milton Avery in 1962, Abstract Expressionists and the emergent Color Field painting of Morris Louis, Kenneth Noland, and Helen Frankenthaler. In the early 70s, contemporary shows became interspersed with the work of European and British masters. New European and American painters and sculptors were introduced in the 80s, and in the 90s, young British artists.

The inventory includes works by modern British masters and important twentieth-century European artists, Henri Matisse, Pablo Picasso, Jean Dubuffet, Josef Albers, Fausto Melotti, and Antoni Tàpies. The long-standing focus on American artists continues with representation of Robert Indiana, Jedd Novatt, the Estate of Allan D’Arcangelo and works by John Chamberlain, Peter Halley, Robert Rauschenberg, Haim Steinbach, Frank Stella, John Wesley, and Julian Schnabel.
