 In the data retention model of the Police National Computer, arrests which do not lead to a finding of guilt "step down" as soon as the relevant decision is made (typically a "not guilty" verdict or a dismissal of charges) and become visible to law enforcement only.Records of cautions and minor convictions do not step down and remain on the PNC and on enhanced CRB checks until the offender's 100th birthday.Since the passing of the Protection of Freedoms Act 2012, people convicted for homosexual acts between consenting adults under section 12 of the Sexual Offences Act 1956 can apply to have the conviction totally removed from their criminal record.
