NDORS Data is NOT shared with insurance companies and they have no access to it.
This is covered by subject access request which allows you to request the information regarding your course attendance. Only you can apply for an extract of data held on police systems. You therefore need to contact the Police Force who sent you the original documentation.
You can normally do this via the Police Force website or contact them on the 101 number. You will need to provide proof of identity.
If not, consider contacting us.
