We've got filters you can apply for anyone under the age of 18. They've been developed in line with the content self-regulation code of practice that we worked with other UK networks to create. They're based on an independent framework produced by the British Board of Film Classification (BBFC).
The BBFC classifies online adult content as anything that can be described as violent, gory, sexually explicit or drug-related in the same way that 18+ film and video content is classified. You can find out more about the classification of adult content on the BBFC site. In support of the UK government's drive to improve internet safety, all services have our internet content filter switched on by default. As long as you're over 18, you can switch this filter off whenever you like.
