EU AI Act 2026: Key Deadlines and What Happens If You Miss Them

The EU AI Act has been law since 2024, but full enforcement doesn’t begin until 2 August 2026. For UK businesses, that date is now less than 100 days away — and the consequences of missing it are significant.

Here’s a clear breakdown of the key dates and what they mean for you.

The first provisions to take effect banned the highest-risk uses of AI outright. These include AI systems that manipulate people subconsciously, social scoring systems, and real-time biometric identification in public spaces. If your business uses any of these, it is already non-compliant.

Rules governing General Purpose AI models — including large language models like GPT-4 — came into force. Providers of these models must publish technical documentation and comply with copyright law. If you are building products on top of AI APIs, these rules may affect you as a deployer.

This is the date that affects the vast majority of UK SMEs. From this date, all obligations relating to high-risk AI systems, transparency requirements, governance documentation, and AI literacy become enforceable.

For a UK SME turning over £2 million, a 3% fine would be £60,000. For a £10 million business, that rises to £300,000.

• Prohibited AI practices — up to €35 million or 7% of global turnover.
• Non-compliance with obligations — up to €15 million or 3% of global turnover.
• Providing incorrect information to regulators — up to €7.5 million or 1.5% of global turnover.

At minimum, most UK businesses using AI need:

• An AI Acceptable Use Policy.
• AI Literacy records for relevant staff.
• Transparency disclosures where AI interacts with customers or employees.

Businesses using AI in hiring, healthcare, finance, credit scoring, education, or law enforcement need significantly more — including Fundamental Rights Impact Assessments, Risk Management Plans, and Conformity Self-Assessment Checklists.
