The DBS will not issue a reprint of your certificate if:

1. Your certificate has been destroyed or lost after you’ve successfully received it.
 2. A DBS certificate reprint has been dispatched, and the copy hasn’t arrived yet.
 3. The DBS check was completed over 3 months ago.

In the lattermost case, you would need to apply for a DBS check online again, as the DBS only issues one reprint per application.
