Here are some of the reasons BBFC use to class there films:
DiscriminationDiscriminatory language or behaviour must not be endorsed by the work as a whole. Aggressive discriminatory language or behaviour is unlikely to be acceptable unless clearly condemned.
Any misuse of drugs must be infrequent and should not be glamorised or give instructional detail.
HorrorModerate physical and psychological threat may be permitted, provided disturbing sequences are not frequent or sustained.
Imitable behaviourDangerous behaviour (for example, hanging, suicide and self-harming) should not dwell on detail which could be copied, or appear pain or harm free. Easily accessible weapons should not be glamorised.
LanguageModerate language is allowed. The use of strong language (for example, ‘fuck’) must be infrequent.
NudityNudity is allowed, but in a sexual context must be brief and discreet.
SexSexual activity may be briefly and discreetly portrayed. Sex references should not go beyond what is suitable for young teenagers. Frequent crude references are unlikely to be acceptable.
ThemeMature themes are acceptable, but their treatment must be suitable for young teenagers.
ViolenceModerate violence is allowed but should not dwell on detail. There should be no emphasis on injuries or blood, but occasional gory moments may be permitted if justified by the context. Sexual violence may only be implied or briefly and discreetly indicated, and must have a strong contextual justification.
