- Mild
- A few mild sex references are made throughout the series, though they are unlikely to cause offence. In one episode a woman is shown undressing and her underwear is briefly visible. In another episode a reference is made of a character trying to 'grope a girl' along with the same character unintentionally touching a women's breasts from another room.
- A mostly clean show aside from Episode 3 "The Wedding Party" from Series 1 and then Episode 2 & 4 "The Psychiatrist" & "The Kipper and the Corpse" from Series 2. Lots of sexual situations in The Wedding Party & The Psychiatrist. And there's a brief scene that features a sex doll in "The Kipper and the Corpse"
- In some episodes a character wears a dress which reveals some cleavage. Nothing suggestive.
- A woman undresses in one episode, but her underwear stays on and we only see her from the back. This is done in the background and is not sexual.
- A man is seen blowing up a sex doll in a room, but nothing is seen and the scene is very quick.
- One episode involves Basil in various situations trying to catch a man sneaking in a girl. Nothing sexual is shown, but various mild, PG references are made and Sybil talks about how it seems Basil is trying to 'grope a girl'.
- A few mild to moderate sex references.
