What are the UK rules on advertising to children?

By Clearance4 min read

Marketing to children in the UK is tightly restricted: ads must not directly urge children to buy or to nag their parents, must not exploit their inexperience or credulity, and face extra limits on HFSS food, age-restricted products, and data collection from under-18s.

What's the rule on pressure and "pester power"?

Ads must not directly exhort children to buy a product or to ask their parents or others to buy it for them — "ask your mum" framing is both a CAP breach and a banned practice under consumer law. They must not exaggerate what a product can do or exploit children's trust.

What are the product and placement limits?

HFSS products face advertising restrictions in children's media and around content appealing to under-16s. Age-restricted products (alcohol, gambling, vaping) must not be directed at or strongly appeal to under-18s — which limits style and characters, not just targeting. Many sectors bar people who are or look under 25 from significant roles.

What about data and design?

Collecting data from under-18s engages the ICO's Age Appropriate Design Code, with high-privacy defaults expected for services likely to be accessed by children.
