In the 1980s Chalmers was a regular host of the Miss World contest on ITV, also presenting the associated UK beauty pageants such as Miss United Kingdom and the British Beauty Championships.
On 19 November 2013, Mark took part in a celebrity edition of Antiques Road Trip alongside his mother Judith Chalmers.
In 2008, she joined Mark Durden-Smith on Wish You Were Here...? Now & Then, a 25-part series where the hosts revisit destinations, originally visited by Judith Chalmers (Mark's mother) and other WYWH? presenters in the original 1974 series, to see how much they have changed.
