Classification

The U symbol stands for Universal. A U film should be suitable for audiences aged four years and over. However, it is impossible to predict what might upset a particular child, especially at this lower end of the category range.

PG stands for Parental Guidance. This means a film is suitable for general viewing, but some scenes may be unsuitable for young children. A PG film should not unsettle a child aged around eight or older. Parents should consider whether the content may upset younger, or more sensitive, children.

Films classified 12A and video works classified 12 contain material that is not generally suitable for children aged under 12. No one younger than 12 may see a 12A film in a cinema unless accompanied by an adult. Adults planning to take a child under 12 to view a 12A film should consider whether the film is suitable for that child. The difference between 12A and 12 is that 12 is simply for DVD 

and Blu-Ray formats

No-one under 15 is allowed to see a 15 film at the cinema or buy/rent a 15 rated video. 15 rated works are not suitable for children under 15 years of age.

Films rated 18 are for adults. No-one under 18 is allowed to see an 18 film at the cinema or buy / rent an 18 rated video. No 18 rated works are suitable for children.

The R18 category is a special and legally-restricted classification primarily for explicit works of consenting sex or strong fetish material involving adults. Films may only be shown to adults in specially licensed cinemas, and video works may be supplied to adults only in licensed sex shops. R18 videos may not be supplied by mail order.
