"Barring
Where requested, an enhanced certificate will also include a check of one or both of the DBS barred lists. If an individual is listed, this will appear on their DBS certificate.
It is our responsibility at the DBS to maintain these lists. This area of our work involves making fair, consistent and thorough decisions that are appropriate to the behaviour that has occurred, and considering the risk of future harm.
People are brought to the attention of our barring team in one of three ways:
automatic barring offence – also known as autobar
disclosure
referral
Automatic – also known as autobar
This is when someone has been newly convicted or cautioned for a serious offence and they are considered for immediate barring, either with or without the opportunity to make representations. This information comes from the Police National Computer.
Disclosure
This is when someone applies for an enhanced DBS check to work with children or adults in certain circumstances, such as those in receipt of healthcare or personal care, and the check reveals relevant information that results in the individual being considered for inclusion on one or both of the barred lists.
Referral
This is when an employer, volunteer manager or other organisation has concerns that someone has either caused harm or has the potential to cause harm to vulnerable groups and submits a referral to the DBS.
Regulated activity providers (employers or volunteer managers of people working in regulated activity in England, Wales or Northern Ireland) and personnel suppliers have a legal duty to refer to DBS where conditions are met."
