You only have to notify employers, insurance and lettings agencies - if asked. They will have no access to the DBS service. Your main problem would be if you turn up in a newspaper search, but you run that risk in daily life anyway.

Hi folks. I have a S.O for images.

I wonder would there be anything to worry about with ordering stock from a supplier - They require Passport photo. Personal details.
They do a KYC (Know your customer check).

I'm guessing they would just be checking for fraud, but wanted to make sure.
Thanks
