Subject of an investigation?

Use the subject portal, not this page.

If you are the subject of an investigation involving CLEARSKY, you do not need to email us. Go to the public subject portal and request a Receipt of Evidence under UK GDPR Article 15. The receipt is built from the same audit log analysts write to, with field-level redaction reasoning. If a redaction looks wrong, lodge an appeal at /subject_portal/appeal.html. Compliance reviews within 14 days. ICO escalation route printed on the appeal page.
