Navigating Influencer Marketing Under the UK Junk Food Advertising Law: What Brands, Agencies and Influencers Need to Know

The UK’s new junk food advertising ban will have a huge impact across the marketing and influencer space.

The ban came into effect on 5 January 2026 and is primarily aimed at reducing exposure to high fat salt or sugar (“HFSS”) food and drink products. The legislation places clear restrictions on paid promotions involving such items across social media platforms like TikTok and Instagram. For brands, agencies, and influencers alike, understanding what these changes mean in practice is critical to staying compliant and avoiding potentially severe consequences.

This article explores the implications of the law for influencer marketing, practical examples of compliant content, what types of videos can be posted, whether there are any exemptions and the consequences of non-compliance.

What Is the UK Junk Food Advertising Law and How Does It Affect Influencer Marketing?

The new legislation prohibits paid advertising of HFSS products online, including through influencer posts, videos, and stories. This means any content involving payment, gifting, or incentives to promote HFSS food or drink products is restricted across all social media platforms.

Influencer marketing will be heavily impacted because even short-lived content like Instagram Stories or TikTok clips will count as “advertising” if there is a commercial relationship. If the content involves paid promotion or gifting, the rules apply equally regardless of format. Failure to adhere may lead to enforcement action from the Advertising Standards Authority (“ASA”), who will be able to dish out a variety of sanctions such as forced content removal, inclusion on a “name and shame” non-compliance list and in the most serious cases, a referral to Trading Standards or the Competition and Markets Authority who may pursue fines under Digital Markets, Competition and Consumers Act 2024 (DMCCA).

What Foods Fall Within the HFSS Category?

Products are classed as HFSS if they score above specific thresholds under the UK nutrient profiling model, which considers calories, sugar, saturated fat, and salt levels balanced against fibre, protein, and fruit or vegetable content.

Common HFSS food and drink examples include fast food and takeaway items such as:

• burgers, fried chicken, pizza with high fat or salt content;

• fried chips, hot dogs, and kebabs;

• confectionery and sweet snacks like chocolate bars, sweets and chocolate spreads;

• desserts and baked goods including cakes, cupcakes, doughnuts, brownies, ice cream, milkshakes, and waffles;

• savoury snacks such as crisps, tortilla chips, cheese snacks, and salted popcorn;

• sugary drinks like fizzy drinks, energy drinks, sweetened iced teas, and fruit drinks with added sugar; and

• sugar-coated cereals, flavoured yoghurts, breakfast bars, and smoothies with added sugar, may be restricted.

How Do These Rules Apply to Different Types of Content?

The distinction between paid and organic content is crucial. Paid or incentivised content featuring HFSS foods is prohibited. This includes branded posts, gifting, affiliate marketing, or any form of payment. On the other hand, organic content (where influencers post about food independently, without any commercial relationship) is not restricted, even if it features HFSS items.

For example, so common videos such as an “unboxing” or promotional posts featuring HFSS products with brand tags are prohibited. Likewise, sponsored restaurant posts with HFSS menu items are similarly restricted.

However, paid content that focuses on the restaurant atmosphere, décor, staff, and experience without showing HFSS dishes is allowed. Highlighting healthier menu options such as grilled lean proteins, vegetable-based dishes, or unsweetened drinks is also permissible.

10 Tips for Compliant Influencer Marketing Under the Junk Food Advertising Law

Brands, agencies and influencers must now consider HFSS compliance as part of their everyday professional practice. The key tips are simple but essential:

Influencer Marketing: A Ray of Hope for Small and Medium-sized Enterprises

There are, however, important exemptions to the rules, most notably for Small and Medium-sized Enterprises (“SMEs”). Companies with fewer than 250 employees (so 249 employees) on the first day of the financial year (April 6th) are outside the scope of the online HFSS advertising ban, meaning they can continue to run paid digital ads for HFSS products, including influencer partnerships, provided they still comply with existing ASA and CAP Code requirements such as not targeting children and clearly labelling advertising.

However, note that the employee count includes all employees, everywhere. If you operate internationally, all employees in every country count toward your total. Employees of parent companies or subsidiary companies who work for your business also count toward the 250-employee threshold.

This exemption applies to the size of the advertiser, not the agency or the influencer, and larger brands cannot rely on a smaller partner’s status to bypass the restrictions. While the exemption is intended to protect SMEs from disproportionate impact, it does not remove the need for responsible targeting, transparency, or adherence to wider advertising standards.

Final Thoughts: The Future of Food Influencer Marketing Post-HFSS Laws

The junk food advertising ban will have a significant impact on the large brands and their influencer marketing strategies. However, influencers can absolutely still generate income by partnering with brands offering non-HFSS products or SMEs.

It is yet to be seen how the influencer marketing space will adapt, but it is likely that large brands will have to pivot to creating experience-led and lifestyle content focusing on ambiance, story, and culture rather than specific HFSS products.

It is certainly not the end for influencer marketing in this sector.
