I contacted my MP after the questions raised on the thread linked below. I asked for clarification about identity checks for DBS could be verified if someone has a GRC and is living with a new identity.

MP didn't bother to reply but I have received the following "correspondence reply" from the Home Office.
Thank you for your email xxx to the Minister for Children and Families about the Disclosure Barring Service ( DBS and your concerns on the effectiveness of the checks that are made on people who are transgender , which has been passed to the Home Office for a reply.
One of the important roles of the DBS is to help employers make safer recruitment deci-sions to ensure that people who want to work with children and vulnerable adults do not have a previous record of causing them harm. An essential part of this public protection role is to check the identity of the applicant through the verification of the documents they use to prove their identity. DBS checks are therefore dependent upon being able to con-firm and verify all names used by an individual when checking whether they might pose a threat to others, for example whether they have been convicted of a serious offence.
For these very important reasons, applicants for a DBS check are asked to produce doc-uments from a primary set (a current valid passport issued by any country, UK photo card driving licence, UK biometric residence permit or a UK birth certificate issued within 12 months of birth) together with other trusted Government issued documents or finan-cial/social history documents. This includes ensuring that the applicant provides details of all addresses where they have lived in the last five years. The DBS guidance has been carefully constructed to ensure that the process is as secure as possible and is kept under review.
Our policies must adhere to the important protections afforded to transgender people, such as protecting an individual’s gender history, which are enshrined in the Gender Recogni-tion Act 2004.
Being able to validate an identity is a crucial part of ensuring that a criminal record disclo-sure is sent to the right person, rather than to someone who has adopted a false identity in order to hide a criminal past. The Government believes that the above process provides the right balance of maintaining high standards of identity checking, whilst at the same time, not being so restrictive that it prevents legitimate applicants from completing the DBS identity checking process.
I hope this is helpful in explaining the position.
So basically "an essential part of this public protection role is to check the identity of the applicant through the verification of the documents they use to prove their identity" unless they have a GRC and then it doesn't matter.
There is no safeguarding.
