This depends on which level of check you apply for. There are three levels in total – basic, standard and enhanced. The basic check will search for just unspent convictions. The standard and enhanced checks search for cautions, warnings, reprimands and convictions. The enhanced check also searches that the applicant isn’t on the barred list for working with children or vulnerable adults and it also allows the police constable at their local police station to relay any relevant information that they think is necessary.
