Snogging is mentioned multiple times throughout the show by kids but is never onscreen.

A few small fights but few and far between. Only shoving and shouting.

Some mild profanity. The characters live in London so there are lots of slang. People are called "you spanner" "you monkey" "you absolute melon" and other random insults. No proper curse words though.

A few characters have somewhat sad storylines or backstories which are addressed more seriously than the rest of the show but nothing too much or anywhere near intense.
