Data Protection Act (DPA): Understanding the UK’s data protection law
The Data Protection Act (DPA) is the primary data protection law in the UK, regulating how personal data is collected, stored, and processed. Furthermore, it is enforced by the UK’s Information Commissioner’s Office (ICO) and ensures that organizations handle personal information lawfully, fairly, and transparently.
The current version of the DPA, known as the Data Protection Act 2018, not only builds upon previous legislation but also incorporates the principles of the UK GDPR following Brexit. Consequently, it governs both public and private sector organizations and sets strict requirements for data processing, security, and individual rights.
