Update, 9 June 2026. The EU institutions have since reached provisional agreement to push the Act’s main high-risk deadline to December 2027. It is not yet law, so the 2 August 2026 transparency date below still stands as your planning assumption. Full context: The EU AI Act’s Big Deadline Might Move to 2027.

A date worth writing down. 2 August 2026. That is when the EU AI Act's transparency obligations become fully enforceable. Eleven weeks away.

A recent Deloitte survey of 500 European managers found that only 26% had started any concrete compliance work. Three quarters of businesses affected by this legislation have not begun preparing for it.

What Article 50 requires

Article 50 of the Act covers transparency. Three obligations, in plain language.

First, when an AI system interacts with a person, that person has to be told. Your website chatbot, your AI-powered contact form, your automated customer service. If a customer is talking to AI, they need to know.

Second, when content is generated or manipulated by AI in a way the public might mistake for real, that fact has to be disclosed. Think AI-generated images, synthetic video, altered audio.

Third, when AI generates text that is published to inform the public, the AI involvement has to be made clear. That covers marketing copy, blog posts, reports and any other content a reader would reasonably assume was written by a person.

The fines

These are not theoretical numbers. Up to €15 million or 3% of global turnover for transparency breaches, whichever is higher. For more serious violations of the Act, up to €35 million or 7% of global turnover.

The enforcement model follows the same pattern as GDPR. Large enough to be a board-level concern, not just a line item.

Why this applies to UK businesses

The Act is extraterritorial. If you have European customers, European staff, European partners or European suppliers, the Act applies to you. The UK is not exempt. This works the same way GDPR did. Where your business is registered is irrelevant. What matters is where the people affected by your AI use are located.

Hands up if you have European clients, European partners or European suppliers. If your hand is up, this applies to you.

The readiness gap

Only 26% of managers surveyed had started any concrete compliance work. That leaves 74% of affected businesses with eleven weeks to go and nothing in place.

The pattern is familiar. When GDPR landed, the same scramble happened. Businesses that had prepared early were calm. Businesses that had not were rewriting privacy policies the week before enforcement. The difference this time is that the obligations are more specific and the fines are larger.

What to do now

Start with a simple exercise. Map every place where AI touches a customer in your business. Check whether that AI involvement is disclosed. Note what data each tool processes. That audit takes ten minutes and gives you a clear picture of where you stand.

The pattern of gaps is your action list. Treat it the way you treated GDPR. Get ahead of it now or scramble in July.
