This is the specific text that defined what is considered "extreme pornography" http://www.legislation.gov.uk/ukpga/2008/4/part/5/crossheading/pornography-etc http://www.legislation.gov.uk/ukpga/2008/4/part/5/crossheadi... It's somewhat disturbing how broad the definition is. For example if an image is in itself not considered pornographic, but is used in a loosely defined pornographic context it can be considered extreme pornography.
