[16] Mould is also a trustee of Benton End, the former home of artist Cedric Morris and Arthur Lett-Haines, who ran the East Anglian School of Painting and Drawing in the house.

His television work includes writing and presenting the Channel 4 series Changing Faces, and featuring as an expert on the Antiques Roadshow.

[24] In January 2014, Mould warned of the increasing prevalence of what he termed "trapping" in which crooked sellers misleadingly hint that fake artworks have genuine provenance, without actually making false descriptions or asserting attributions.

[29] Mould described some of the basics concepts for art discoveries, in an article published in The Guardian: Although [Mould] acknowledged that auctioneers do not have the benefit of cleaning and restoring works, which help to reveal true quality, he added: "As art dealers, we scour daily the world's auction catalogues for paintings that are ... wrongly identified ...

In any week, our finds might range from a misidentified Tudor icon to a misattributed 18th-century landscape … but by a strange chance we seem to have hit a seam of Van Dycks.

[31] In August 2014, Mould was one of 200 public figures who were signatories to a letter to The Guardian opposing Scottish independence in the run-up to September's referendum on that issue.

[33] Mould is a keen collector of Morris's work (for his private collection), and champions modern British artists in general; he cites the Bloomsbury Group amongst his favourites.

[4] In April 2020, during the COVID-19 pandemic, Mould started recording a series of short videos he calls Art in Isolation, where the viewer is invited into his home of Duck End and given personal musings on one of his collected artworks.
