Miles Heseltine was born in Cornwall and completed an Art Foundation course at Falmouth School of Art before going on to study painting at Norwich School of Art. On graduating in 1989, he worked as a singer, songwriter and musician with an international touring band.

He returned to Cornwall in 2006, and the following year his artwork was exhibited in the show 'Revolver' at Penzance Art Gallery. In 2009 he was awarded the RWA drawing prize, and in 2010 his work was included in the RWA's annual open exhibition.

Heseltine's work has been shown widely in Cornwall, London and France, and is held in significant private collections. He is represented exclusively by Beside the Wave.
