Chedgey was educated at Ealing, Twickenham and Liverpool Schools of Art, before embarking on a 28 year teaching career culminating as Head of Art at Wymondham College where he taught, among others, Hollywood film idol Mark Strong, the British photographer Frances Kearney and the Health Minister Norman Lamb, all three of whom are the subjects of recent portraits, a field in which he specialises.
He was a member of the Groupe de Recherche des Arts Visuelles, along with such luminaries as de Soto, Le Parc and Vasarely whilst teaching in Germany. where he exhibited regularly at the Denise Rene Galleries for kinetic art in Krefeld and Paris. He is currently (2016) a member of Caper Art and the Norwich 20 Group with whom he exhibits several times a year. He has work in private collections worldwide and in many public collections including a sixteen feet by four feet group portrait of fellow artists which hangs in the City Hall in Norwich. He was commissioned in 2015 to paint a large triptych on aspecially built wall in The Church of St Mary the Virgin in Kelling, Norfolk. The church followed up with a further commission for an icon of the Mother and Child to be placed on the altar steps.
He is widely known for his quirky and often disturbing photorealist sculptures in which he takes casts from live models recreating them in polychromed silicon rubber with implanted human hair and glass eyes. ‘Tutsi Warrior’, a teen-aged Ruandan soldier with a machine gun, sat for years on the roof of his College Road house. ‘The Man who ate too many clocks’ a dissected corpse with a bellyful of alarm clocks was the cause of a police visit to the Norwich Assembly Rooms and ‘I could be a GREAT surgeon!’ which depicted an autistic hospital cleaner carefully dissecting his own left hand which supposedly caused a shoplifting woman to faint in The Forum in Norwich.
