UK Bans Junk Food Ads: A Global First

The United Kingdom’s Advertising Standards Authority (ASA) has barred two supermarket advertising campaigns after finding they breached new restrictions on marketing products high in fat, salt and sugar (HFSS). The ASA said the rulings, announced Wednesday, represent the first enforcement action under rules that took effect on January 5.

The regulations limit where and when HFSS advertising can appear. Under the framework cited by the ASA, HFSS promotions are not allowed on television before 9 PM, and they are prohibited in paid online advertising spaces at any time. The ASA said both cases involved digital marketing that fell within the scope of the new limits.

In one decision, the ASA found that Lidl Northern Ireland promoted bakery products, including pain suisse, through an Instagram post published by influencer Emma Kearney. The regulator concluded the post amounted to advertising for an HFSS product that is restricted under the January 5 rules. Lidl acknowledged that the content promoted an individual product that is banned under the restrictions, while stating it had intended the activity to be a brand-led campaign.

In a separate ruling, the ASA said Iceland Foods placed digital display and banner advertising on the Daily Mail website that featured confectionery items such as Swizzels Sweet Treats and Haribo Elf Surprises. The ASA said these products are classified as HFSS, bringing the ads under the online prohibition described in the rules. Complaints were submitted about both the Lidl and Iceland promotions, and the ASA said it upheld those complaints.

Following the decisions, the ASA instructed both supermarkets to ensure future digital marketing complies with the HFSS advertising restrictions. Iceland said it is strengthening its data collection processes to help identify HFSS products and prevent them from appearing in advertising.

For global consumer brands and retailers, the rulings underscore how quickly enforcement can begin after new marketing rules take effect, particularly in paid online environments where targeting and placement can be complex. The cases also highlight the compliance risks associated with influencer-led promotions and third-party website advertising, where product-level content can trigger restrictions even when a campaign is designed to emphasize a broader brand message.

What remains unclear from the ASA announcements is whether additional enforcement actions are imminent, or how frequently similar complaints may be upheld as advertisers adjust to the January 5 framework. The ASA’s direction to the companies focuses on future compliance, leaving open questions about how retailers will operationally screen product content across fast-moving digital formats.
