UK GDPR Article 22 — Automated Decision-Making
Right to human review: if your AI makes a significant decision automatically (loan approval, insurance premium, clinical diagnosis), you must provide a right to request human review.
Right to explanation: individuals have the right to an explanation of automated decisions that significantly affect them — the "black box" defence is not permitted under UK GDPR.
DPIA required: automated decision-making with significant effects requires a Data Protection Impact Assessment (DPIA) before deployment.
Meaningful human oversight: "human in the loop" must be genuine — not rubber-stamping. FCA supervision: FCA expects human reviewers to have genuine capacity to override AI decisions.
Article 22 UK GDPR: individuals have the right not to be subject to decisions based solely on automated processing that produce significant legal or similarly significant effects. Applies to: automated credit scoring, automated insurance pricing, automated recruitment screening, AI medical diagnosis without human review.
Building RAG (Retrieval Augmented Generation) for UK Business
| RAG Component | UK GDPR Consideration | ClickMasters Approach |
|---|---|---|
| Document ingestion | Personal data in documents → UK GDPR processing activity. Legal basis required. | Identify and tag personal data in document corpus. Separate processing from non-personal knowledge base. |
| Vector embeddings | Embeddings may reconstruct original personal data. UK GDPR Article 25. | Use UK GDPR-compliant embedding API. Consider pseudonymisation before embedding personal data. |
| Retrieval (similarity search) | Retrieved chunks may surface personal data without appropriate access control. | RBAC on retrieval — user can only retrieve documents they have permission to access. |
| LLM generation | Prompt may contain personal data → LLM processes personal data. Article 28 DPA required. | DPA with AI API provider. EU data residency. No training on customer data (confirm with API provider). |
| Generated output | AI may hallucinate personal data about real individuals. | Output filtering for PII. Human review before displaying AI-generated content about individuals. |
ICO AI Auditing — What to Expect
Transparency: are users told they are being subject to AI-assisted decisions? Privacy notice must mention AI processing.
Fairness: is the AI producing biased outcomes by protected characteristic? ICO expects bias testing evidence.
Accuracy: is AI output accurate and up to date? Stale training data can violate Article 5(1)(d) accuracy principle.
DPIA: for high-risk AI (automated significant decisions, large-scale processing of special category data), DPIA is mandatory.
Data minimisation: AI should not be trained on more personal data than necessary. Article 25 data minimisation applies to AI training.
The ICO has published AI auditing frameworks and is actively auditing UK organisations using AI for high-risk processing. ICO AI audit focus areas:
