Criminal records
Fines, warnings or reprimands don't show up if someone performs a basic criminal record check.
If you come to the end of a community rehabilitation or community punishment order without committing any further offences, your conviction will be spent after five years, or two and a half years if you were under 18. That means that it will not be included on a basic criminal record check if you're applying for a job.
If you're looking for work that will involve working with children, your employer will have to carry out a more in-depth check on your record. An intermediate or enhanced record check will show all criminal convictions and police warnings, including fines and reprimands. However, all employers will still have to decide whether the details of your record are still relevant and they may affect your application for the job.
