These Regulations amend the Data Protection (Notification and Notification Fees) Regulations 2000. Under the Data Protection Act 1998, all data controllers are required to provide a notification to the Information Commissioner and be included on the register of data controllers. A prescribed fee must accompany notification. These Regulations replace the flat fee with a two-tiered fee structure: £35 for tier 1 and £500 for tier 2. Turnover and number of staff within the organisation determine the relevant tier and requisite fee.
