UK Data Protection Act 2018 — Law Enforcement Processing

Jurisdiction: United Kingdom (GB) Frameworks addressed: Data Protection Act 2018 Part 3 (Law Enforcement Processing), enforced by the Information Commissioner's Office (ICO). Registration tier: Open Review status: initial_draft Review date: 2026-03-21


Overview

The Data Protection Act 2018 Part 3 establishes a separate and distinct regime for the processing of personal data by competent authorities for law enforcement purposes, implementing the EU Law Enforcement Directive (LED, 2016/680) in UK law. This regime operates entirely separately from UK GDPR and applies to processing by courts, police forces, prosecuting authorities, and other competent authorities for the purposes of prevention, investigation, detection or prosecution of criminal offences, execution of criminal penalties, or the safeguarding and prevention of threats to public security.

Part 3 has distinct lawful processing conditions, purpose limitation requirements, data subject rights (which are more restricted than under UK GDPR), data protection by design obligations, and mandatory Data Protection Impact Assessments for high-risk processing.
