Will a caution show up on a CRB check?

Criminal Records Bureau (CRB) Checks were replaced by Disclosure and Barring Service (DBS) Checks in 2012.

Basic criminal record checks do not show cautions. Standard and Enhanced DBS checks show cautions that are not 'protected' under current legislation. A caution for an offence that is on the prescribed 'list of offences that will never be filtered from a DBS certificate' will always show on standard and enhanced DBS checks.

A caution for an offence that is not on that list will become 'protected' once 6 years have passed (2 years if the person was under 18 at the time of caution). Once 'protected' it will no longer show up on a standard DBS check and will only show on an enhanced DBS check if the police believe it is relevant.
