ICO stands for the Information Commissioner’s Office (ICO), it is the UK’s independent data privacy regulator. The ICO has the power to investigate data breaches and impose large fines on organisations, who fail to meet the requirements of the Data Protection Act or GDPR. While the ICO does not award compensation, you may request the ICO to assess if an organisation is at fault for a data breach and to collect evidence, which can be helpful to claim compensation.
