If you work in food marketing, you'll already know the HFSS advertising restrictions weren't a single overnight change — originally due in October 2025, they were pushed back and finally came into force UK-wide on 5 January 2026, with many advertisers and broadcasters voluntarily complying from that original October date. For brand and marketing teams, that staggered rollout has made it genuinely hard to keep track of exactly what's restricted, where, and since when. Here's where things actually stand.
What the HFSS Advertising Restrictions Cover
The restrictions apply to products classified as HFSS under the UK's Nutrient Profiling Model — the same scoring system that governs in-store location and promotion rules. Since 5 January 2026, advertising for these products has been restricted UK-wide in two main ways:
- A 9pm television watershed — HFSS product advertising is restricted from television, including on-demand programme services, before 9pm, when children are more likely to be watching.
- A total restriction on paid-for online advertising — paid HFSS advertising online is restricted at any time of day, reflecting how much of children's media consumption has shifted online.
The rules apply to the advertiser, not just the broadcaster or platform, which is why marketing and brand teams — not just media buyers — need to understand exactly which products in a range are affected before a campaign is planned, not after. Unlike the in-store rules, there is no small-business or out-of-home exemption from the advertising restriction.
The Brand Advertising Exemption
One genuinely useful carve-out for marketing teams: advertisements that promote a company or range brand without depicting a specific HFSS product are exempt. The test is based on the content of the advert itself, not on brand association or perception — so a corporate or range advert is fine, but it can't name or visually depict a specific less healthy product, use realistic images "visually indistinguishable" from one, or feature branding and characters tied to a specific HFSS product. Get your creative right, and brand-level campaigns can continue to run in slots and formats that a product-specific ad for the same range could not.
Why This Matters More Than the In-Store Rules
The location restrictions, which arrived first in October 2022, and the volume price promotion restrictions, which followed in October 2025, changed where a product sits on a shelf — and both only apply in England, to businesses with 50 or more employees. The UK-wide advertising restriction goes further — it changes whether a campaign can run at all in a given slot or format, for businesses of any size. For brands that have built marketing calendars around TV and online video, this has meant either restructuring media plans around HFSS status, leaning on the brand advertising exemption, or reformulating the products themselves so they fall outside the classification entirely. Media budgets committed months in advance are exactly where the cost of getting this wrong shows up fastest, which is why the earlier a product's HFSS status is confirmed, the less disruptive the restrictions end up being.
What Marketing and Brand Teams Should Check
- Confirm the Nutrient Profiling Model score for every product likely to feature in an upcoming campaign — not just the "hero" product, but anything visible in the background of the creative.
- Build HFSS status checks into the campaign approval process, not as an afterthought before launch.
- Where a product sits close to the HFSS threshold, flag it early to the product or NPD team — a modest reformulation can sometimes remove a product from scope entirely and open up media options that would otherwise be off-limits.
- Keep a record of your assessment and rationale for each campaign — if a product's status is challenged, you'll want to show your working.
What Isn't Restricted
It's worth being precise about the boundaries, because I've seen campaigns paused unnecessarily out of caution when they didn't need to be. The restrictions are specifically on paid-for advertising of HFSS products — they don't extend to owned channels such as a brand's own website or social media posts that aren't boosted or promoted, editorial or PR coverage that a brand doesn't pay for, or advertising for non-HFSS products in the same range. Business-to-business advertising, aimed at retailers or trade buyers rather than consumers, sits outside the consumer-facing restrictions too. None of this is a loophole to lean on for HFSS products specifically, but understanding exactly where the line sits stops teams from over-restricting their own activity unnecessarily.
Reformulation as a Marketing Enabler, Not Just a Compliance Task
It's easy to treat HFSS compliance as something that sits with legal or regulatory affairs, separate from marketing. In my experience, the two are much more connected than that. In my previous role leading HFSS legislation compliance for Aldi across Great Britain and Ireland, I saw directly how reformulation decisions — reducing sugar or saturated fat, adjusting portion sizes, increasing fibre — could bring products back into scope. Getting reformulation and marketing talking to each other early tends to produce better outcomes than treating compliance as a final checkpoint.
Getting HFSS Advertising Compliance Right
If your business needs clarity on which products are affected, or wants to explore reformulation as a way to open up advertising options, this is exactly the kind of work I support food brands and retailers with.
