There are important exceptions where spent cautions and convictions may still need to be disclosed.
These exceptions are listed in:
The Rehabilitation of Offenders Act 1974 (Exceptions) Order 1975.
They cover jobs and activities where fuller criminal record information is relevant, for example:
Roles involving a risk to children
Roles involving a risk to vulnerable adults or others in vulnerable circumstances
Certain sensitive areas of work, such as specific regulated professions, security, or high-trust positions
In these situations:
You are normally required to undergo a Standard or Enhanced DBS Check.
Those higher-level checks can show certain spent convictions and cautions, in line with the Exceptions Order and DBS filtering rules.
