UK GDPR guidance for Lawful Bases, with practical decisions, evidence, edge cases, and external source citations. *Artifact Guide* *UK* *Lawful Bases* ## UK GDPR Lawful Bases Lawful Bases decisions under the UK GDPR should be written in operational language: who is in scope, what must happen, what evidence proves it, and when escalation is needed. This guide converts requirements into implementation-ready ownership, evidence, and review decisions. It is practical guidance, supporting implementation planning and should be validated against jurisdiction-specific legal, contractual, and policy requirements before implementation. The UK GDPR has seven lawful bases: consent, contract, legal obligation, vital interests, public task, legitimate interests, and recognised legitimate interest. Teams should pick the basis that matches the actual purpose of the processing and document why it applies before they start processing personal data. ## How should teams choose a lawful basis under the UK GDPR? Teams should treat Lawful Bases under the UK GDPR as a source-linked operating decision: confirm whether the issue affects controller/processor roles, lawful basis, transparency, DPIA, data-subject rights, breach notification, IDTA/Addendum transfers, children data, or ICO enforcement exposure, assign the team that can change the process, and keep evidence showing the action and review trigger. The safest first step is to identify the controller/processor role, purpose, lawful basis, special-category status, right, breach, transfer, or child-data trigger before assigning the UK GDPR action. - Write the Lawful Bases decision in one sentence before drafting controls. - Attach the external source URL and a short source quote to the evidence record. - Route unclear cases to legal, privacy, security, or compliance review before launch.

Useful evidence is not just a privacy notice. Keep the source, lawful-basis note, DPIA, rights log, breach assessment, transfer mechanism, processor terms, and approval trail together. - Source URL and quote used for the decision. - Scope notes, screenshots, data-flow or system references, and role mapping. - Implementation ticket, approval record, exception notes, and review date.

The common failure pattern is copying an EU GDPR answer without checking UK GDPR wording, DPA 2018 limits, ICO guidance, UK transfer tools, PECR overlap, and post-Brexit divergence. - Using an old threshold, deadline, source page, or contract template without checking current source text. - Treating a source-linked exception as a general exemption for every product or data flow. - Publishing notices, controls, or answers that do not match the actual product behavior.
