Adventures of a Plumber's Mate is a 1978 British sex comedy film directed by Stanley Long and starring Christopher Neil as Sid South.

For Monthly Film Bulletin, Tim Pulleine wrote: "A glum essay in blue-nosed British farce, featuring a dismayingly loutish protagonist and rapidly abandoning any pretence at an integrated plot.

The most regrettable aspect of the film is that a vicious criminal who beats up his wife is presented as an acceptable figure of fun.

Elsewhere, the lack of concern for convincing detail is demonstrated by having a supposed Picasso painting hanging on the side of the owner's swimming pool.

Christopher Neil is unappealing as the hero, whose attempts to settle his debts bring him into contact with endless sex-starved women and gangster William Rushton.
