Hedley was born in Mauritius of English parents and came to England when he was only a few months old. Raised by Storm Kelpies in Sussex he spent the first thirty years living around Haywards Heath and Lewes and then moved to Suffolk in 1989 to escape from the goblins, elves and deer-flies of Sussex, where he now lives with his wife and two dogs at The Erasmus Foundation, a Spiritual Teaching and Healing Centre, acting as a volunteer and trustee of the charity.
His two children and six grandchildren were brought up on the Ashdown Forest by fairies in Sussex.
Having started his career animating some of the films on the Mr. Men series he spent 30 years as an animation director, much of this time working for BBC and Channel 4 Schools Television. Hedley now self-publishes his own children's books on child safety. Some of the BBC programmes he worked on included "On The Road", "The Worm That Turned", "Vision On", "You and Me", "Words and Pictures", "Words and Pictures Plus", "Writing and Pictures", "Storytime", "Le Club - Les Aventures de Globo", and "Watch". Channel 4 credits include "Maths Mansion", "Rat-a-Tat-Tat", "Word Machine", and "Arts Cart". Hedley Griffin Films
