How to Escalate a UK Data Protection Complaint to the ICO

how to escalate a UK data protection complaint or personal data breach concern to the ICO

This guide addresses “how to escalate a UK data protection complaint or personal data breach concern to the ICO”. Its topic-specific anchors are escalate, data, protection, personal. The analysis separates evidence, procedure and available action rather than relying on a generic form.

Who should you complain to first?

If you believe an organisation has mishandled your personal information, start by making a clear data protection complaint to that organisation and keep the response, relevant correspondence and evidence of the issue. If the matter remains unresolved, the Information Commissioner’s Office (ICO) is the UK regulator that can consider data protection complaints. For a personal data breach, record what happened, what information was affected, when you learned about it, what the organisation told you and what outcome you requested.

Use the ICO’s current guidance rather than relying on an old template. Data protection complaint procedures changed in 2026, so the date of the organisation’s response and the latest ICO instructions matter when deciding the next step.
