When AI-Generated Marketing Images Mislead Customers: A UK Business Checklist
AI-generated images can mislead customers when they make a product, service, or result look materially different from what customers can actually expect. UK law does not ban AI imagery or require every AI advert to disclose it, but the overall marketing must not mislead consumers

What the law says
The Digital Markets, Competition and Consumers Act 2024 applies to UK business-to-consumer commercial practices from 6 April 2025. Section 226 addresses false or misleading information and an overall presentation likely to deceive, while section 227 addresses certain omissions of material information.
The legal question is not simply whether an image was generated by AI. It is whether the image and its surrounding presentation could mislead the average consumer about something relevant to their decision, and whether that could lead them to make a different transactional decision.
The ASA and CAP say there is no blanket UK legal requirement to disclose AI use in every advert, and their existing advertising rules apply whether content is AI-generated or not. They also warn that an AI-generated cosmetic-results image that does not reflect real-world outcomes may be materially misleading, and that an AI label alone is unlikely to fix a fundamentally misleading message.
When an AI image risks misleading customers
A generated image can create a false impression if it changes a product’s apparent size, colour, features, ingredients, packaging, or performance while presenting the result as an accurate depiction. These details may matter because the CMA identifies product characteristics and expected results as information that can influence a consumer’s decision.
The same concern can apply to services when an image appears to show a real completed project, venue, treatment outcome, or customer experience that the business cannot substantiate. The risk depends on the overall context, including nearby wording, captions, disclaimers, and where the image appears.
AI imagery can also be used responsibly, such as for a clearly illustrative concept image that does not imply it is a photograph of the actual product or a guaranteed result. The goal is not to ban creative tools; it is to ensure customers understand what they are being shown.
A practical checklist for businesses
Use this checklist as a practical review for UK business-to-consumer marketing, not as a legal guarantee. The DMCC Act applies to the overall commercial practice, so review the image together with its caption, claims, product page, and purchase context (Act; CMA guidance).
Identify what it shows. Is it a real photo, concept image, mock-up, or result illustration? Label or describe it so customers are not left with the wrong impression.
Check it against reality. Verify visible details and included features against the actual product or service. Change anything that could create a materially inaccurate expectation.
Back up results claims. Keep evidence for outcomes suggested by the image, especially before-and-after or health-related claims. Do not present a generated result as proof of what customers will achieve.
Explain AI use when it matters. Could customers mistake the image for a real photo, customer, or typical result? If that misunderstanding matters, make the illustrative or generated nature clear and noticeable.
Do not rely on a label alone. “AI-generated” does not make an inaccurate claim or unrealistic result accurate. Revise the image or claim if the overall impression misleads.
Make key context easy to see. Show important characteristics, limitations, or result information before customers decide. Do not hide it in hard-to-find small print.
Check every placement. Review the image in ads, listings, social posts, and mobile layouts. Crops or missing captions can change its meaning.
Test the impression. Ask someone unfamiliar with the image what they think it shows and expect to receive. If that differs materially from reality, revise the image or wording.
Keep review records. Save the final image, supporting evidence, and approval notes. This is a practical safeguard, not a specific recordkeeping duty stated in the Act.
Review the full customer view. Check the image with its caption, price, and purchase context before publishing. Confirm the overall presentation accurately reflects what is offered.
The takeaway
AI-generated marketing images are not automatically deceptive, and UK rules do not require every AI-made advert to carry a universal AI label. Businesses should focus on whether the complete presentation gives customers an accurate understanding of the product, service, and results they can expect.
This checklist is general information, not legal advice, and it cannot guarantee compliance in every case. For a specific campaign or regulated product, get advice suited to the facts and the rules that apply to that sector.
