What it requires
The EU AI Act is the world's first comprehensive horizontal AI law, applying a risk-based regime across all 27 member states — and to any company serving EU users. Prohibited-use bans already apply; high-risk system obligations (conformity assessment, technical documentation, human oversight) phase in through August 2, 2026.
The UK has deliberately not enacted an EU-style AI Act. Instead, five non-statutory principles are applied by existing sector regulators — the ICO for data protection, the FCA for financial services, Ofcom for online safety. The AI Security Institute (renamed from the AI Safety Institute in February 2025) oversees frontier-model risk, and the Data (Use and Access) Act 2025 reformed the rules on automated decision-making. A comprehensive government AI Bill has been signalled for 2026 but is not yet before Parliament.
