Ok thanks. If a person receives a formal criminal conviction, it is initially treated as ‘unspent’, until a specified rehabilitation period has passed, after which it is considered ‘spent’. These periods are determined by the Rehabilitation of Offenders Act 1974. Your conviction would have become spent at the end of the sentence, plus an extra 4 years after that.
Whether a past caution or conviction will appear on it depends on what level of DBS checking is being undertaken. Standard checks contain spent and unspent convictions, as well as cautions, reprimands and final warnings
There is also a filtering system in place which removes spent convictions subject to certain conditions. The current guidelines are:
Convictions - a spent adult conviction will not be included on a DBS check if 11 years have elapsed since the date of conviction, it is the person’s only offence and it did not result in a custodial sentence.
This last part is the most important for you because yours did result in a custodial sentence which means that even though it is spent, it should still be included on a Standard check because that would show spent convicitons as well, unless they are filtered out but yours will not be filtered out as it was custodial.
Does this answer your query?
