The first thing would be to get the information relevant for a DBS check. To do this, you will need to submit two requests:
- Request a copy of your criminal record, by asking for a "basic DBS check" (Request a basic DBS check).
- The "standard" and an "enhanced" DBS Check may supply an employer with additional information, in particular whether you are on a "barred list". To request this information, you must Make a subject access request to DBS.
Note that the "enhanced" DBS check may also contain information held by local police. You cannot request this information from the DBS However, you can use a "subject access request" to find out whether such information was supplied by DBS in the past. You may also be able to find this information by directly asking local police services.
If there is an entry about the safeguarding issue, you at least know where you stand. If you believe the entry is unjustified, you can fight it (see e.g.
Report a problem about a criminal record check or barring decision). However, that is a different (probably complex) problem.
If you choose to accept the entry, you will then have to find out which jobs will (and are allowed to) still accept you. Consider asking a new question, once you know what your entry says.
Finally, as the other answers explain, this is a complex subject, so you should probably get qualified help, such as Citizens advice or legal assistance.
