ICO's Growing Focus on AI
The Information Commissioner's Office has signaled that AI compliance is a priority area for 2026. Recent enforcement actions provide valuable lessons for businesses of all sizes.
Key Cases and Lessons
Case 1: Automated Decision-Making Without Disclosure
A recruitment platform was fined £2.3 million for using AI to screen candidates without proper disclosure. The key failures were:
- No mention of AI in privacy notices
- No option for human review of decisions
- Candidates weren't informed their applications were AI-assessed
Lesson: Always disclose automated decision-making and provide human review options.
Case 2: Excessive Data Collection for AI Training
A marketing company received a £1.8 million fine for collecting excessive personal data to train AI models. Issues included:
- Collecting data beyond what was necessary
- Retaining data indefinitely for "future AI improvements"
- No lawful basis for the AI training use
Lesson: Apply data minimization principles to AI training data.
Case 3: Inadequate Security for AI Systems
A healthcare provider was fined £4.1 million after an AI system breach exposed patient data. Problems identified:
- AI system had weaker security than main systems
- No regular security testing of AI components
- Delayed breach notification
Lesson: AI systems need the same security standards as your core infrastructure.
