ChatGPT ads are live in the UK. What brands should do first
Ads now sit underneath ChatGPT answers for free users in the UK. Here’s how they work, what they can’t do, and how to test them without wasting budget.
OpenAI started testing ads in ChatGPT in the US at the start of 2026 and has since switched them on in the UK. For marketers, that makes the most-used AI assistant a paid media channel for the first time, and it arrives while people are still working out how to show up in AI answers organically.
How the ads work
Ads appear for logged-in adults on the Free and Go plans. Paid plans such as Plus, Pro, Business, Enterprise and Education stay ad-free. Sponsored units show up beneath a response, clearly labelled, and are matched to the context of the conversation rather than bought on keywords in the way search ads are [1][2].
OpenAI’s stated principles matter for how you plan: it says ads don’t influence the answers ChatGPT gives, and advertisers don’t get access to people’s conversations [1]. In the UK, personalised ads depend on user consent; people who don’t consent see contextual ads only [2].
What that means in practice
You can’t buy your way into the answer. Organic visibility in AI answers still comes from being clearly described, well reviewed and widely cited across the web.
Context beats keywords. Describe the situations your customer is in, not just the terms they type. Brief creative for those moments.
Start small and measure properly. Treat the first budget as a test with a control, a clear conversion event and a set review date.
Our take
Don’t move search budget wholesale. Put a ring-fenced test budget behind two or three high-intent situations, run it for six to eight weeks, and compare cost per qualified lead against your existing search and social benchmarks. Keep investing in the content that gets you mentioned in answers, because that’s still where most of the attention is.
