What certificate is PG13 in the UK?

Answer 1

In the US, a movie rating of PG-13 means "Parents Strongly Cautioned. Some material may be inappropriate for children under 13."

The closest equivalent in the system established for the UK by the British Board of Film Classification (BBFC) is a rating of "12" which means "No one under 12 years of age may see a '12' film or rent or buy a '12' video."

There is also a rating of "15", meaning "No one under 15 years of age may see a '15' film or rent or buy a '15' video

From this quote below PG 13 Is Most Similar to 12A

Quote from BBFC:" The '12A' category exists only for cinema films. No one younger than 12 may see a '12A' film in a cinema unless accompanied by an adult, and films classified '12A' are not recommended for a child below 12. An adult may take a younger child if, in their judgement, the film is suitable for that particular child."
