The Disclosure and Barring Service (DBS) has updated the identity (ID) checking guidelines for all levels of disclosure check.
Gov.uk stated:
Registered Bodies and Responsible Organisations are required to check the identity of people that apply for basic, standard or enhanced certificates via their organisation.
The new guidelines can be used from 3 September 2018. However, to ensure a smooth transition, the old guidelines will run in parallel until 3 December 2018. They will then cease to apply and only the revised ID checking guidance will be valid.
The guidelines for Responsible Organisations carrying out basic checks can be found here and the guidelines for Registered Bodies carrying out standard or enhanced checks can be found here.
