Do I need a DBS check (previously CRB) to volunteer with WDP? Yes. All volunteer roles require a full Disclosure & Barring Service (DBS) check (previously a CRB check). Once you receive your approved DBS check, please let the WDP Volunteering team know as we would need to make a copy for our records. Without a valid DBS check, you can start your role but you will not be able to do any one-to-one work with service users. For any volunteering roles involving work with families and children, unfortunately you will not be able to start your volunteer role until you show us your completed DBS check.
