The BBFC guidelines are used to classify films and videos before release based on their content such as violence, language, sexual content and drugs. This ensures consumers are informed and the highest protection of children. Films are given age ratings from U to 18. Higher ratings mean content is only suitable for older audiences and may contain stronger language, violence or sexual content. The BBFC examines all films and will intervene more often for videos which are more accessible to younger viewers. Exceptions to the 18 rating are made if content is illegal or may cause harm.
