This depends upon your employer and in some cases the law.
For those who have applied for a role involving the care of vulnerable adults, the Department of Health (DH) allows applicants who have applied for an enhanced DBS disclosure to start working with vulnerable adults under supervision. This is dependent upon the person not appearing on the adult’s barred list (a list of people barred from working with vulnerable adults).
Employers are able to check this via an Adult First check, available through TotalCRB, to care homes, domiciliary care agencies and adult placement schemes.
