The British Board of Film Classification reviews films and assigns them age ratings based on their content. They consider factors like discrimination, drug use, violence, language, nudity and sex. For the film in question, the BBFC would likely rate it 15 due to the large amount of strong violence that could be imitable to younger viewers, such as a character being hit with a shovel in a first-person shot. Several shots of a bruised body being dragged through the woods could also disturb younger audiences.
