Criminal Records (Clean Slate) Act 2004
It’s not illegal for an employer to ask if you have a criminal record. However, you have the right, in some situations, not to tell employers about your criminal convictions. To be able to do this you must not have had any convictions in the last seven years, and you must have never been sentenced to prison (see “The clean slate scheme” in the chapter “The criminal courts”). This means that even if the employer asks you directly, you can tell them that you have no criminal record.
