He worked for D. C. Thomson & Co. and IPC Magazines in a career that spanned over 30 years, on comics such as Bullet, Scorcher, Hornet, Action, Roy of the Rovers, Victor and Scoop, amongst others.

[1] Originally a Catholic, he became a born-again Christian in 1980, joining the Isle of Wight Full Gospel Business Men's Fellowship, of which he became Vice-President, and the Sacred Heart of Jesus Music Group.

[1] Work in comics began to dry up in the early 1990s after Roy of the Rovers and The Victor ceased publication, so Harding became an Independent Arts teacher, using art to help people recovering from strokes, and worked with people with disabilities at Meadowbrook Day Care Center,[1] where he founded the Isle of Wight Re-Cycle project, collecting over 1000 bicycles for Africa.

[6] He suffered from an irregular heartbeat, and died suddenly on 12 January 2014, aged 72, while returning from work as a carer at Afton Ward at the Sevenacres mental health unit.

Harding regarded it as a "cheeky", humorous story,[8] but objected to some of the things he was asked to draw, for example refusing to depict Lefty sticking two fingers up to the crowd.
