Influencer Matchmaker has warned that the UK's planned ban on social media access for under-16s will force brands to rethink youth-focused influencer campaigns. Most youth-facing creator briefs the agency reviewed still centred on short-form social video platforms.
An internal review of 183 youth-facing creator briefs handled or reviewed by Influencer Matchmaker found that 68% placed TikTok, YouTube Shorts or Instagram Reels at the centre of campaign planning. Only 19% included a clear parent-facing, family-safe or non-social route to reach younger audiences.
The warning follows government plans to block under-16s from major social media platforms, including TikTok, YouTube, Snapchat, Instagram, Facebook and X. The policy is expected to reshape how advertisers, agencies and creators approach campaigns aimed at younger consumers.
Influencer marketing has become a common route for brands in sectors including fashion, beauty, gaming, fast food, sportswear, entertainment and education. Many of those campaigns have relied heavily on short-form video, creator-led trends and platform feeds to build awareness and influence buying decisions among younger audiences.
Jack Hayes, founder of Influencer Matchmaker, said the proposed rules would bring greater scrutiny to how brands identify and measure youth audiences.
"Youth marketing has had an uncomfortable dependency on feeds where age, influence and intent are hard to separate. That model now has a deadline.
Brands have been able to buy attention around youth culture without always proving who was actually being reached. The under-16 ban will make that much harder to defend. If a campaign is built on vague reach, loose audience data and creators with heavy school-age followings, it will become a brand safety problem," Hayes said.
Analysts have already pointed to a wider financial effect across the advertising market. Reports citing eMarketer forecasts suggest the restrictions could remove £1.3 billion from projected UK digital advertising spend in 2027 as marketers reassess how they reach younger users.
The expected change goes beyond media buying and extends to creator selection. Brands may need to place more weight on whether a creator's audience profile is clear, whether content is suitable for family settings and whether campaigns can reach parents, households and older teenagers without breaching the intended boundary around under-16s.
Hayes said the shift would also put pressure on creators whose followings are rooted in teenage social media culture.
"Creators who rely on teenage feed culture will need to mature quickly. Brands will ask tougher questions about audience age, content safety, platform mix and whether a creator can speak to households, parents and older teens without crossing the line.
The creators who win from this will be the ones with clean audience data, trusted communities and content that can sit safely around family, education, sport, entertainment and retail. Those selling reach without clarity will struggle," he said.
For marketers, that means reviewing more than headline follower numbers and engagement rates. Campaign audits are likely to include checks on creator audience breakdowns, historic performance data, paid amplification plans and whether there are workable routes to market that do not rely entirely on social feeds.
Campaign reset
Parent-facing communication, retail partnerships, live experiences, school-safe activity, family media and creators with older or professionally defined audiences could all take on greater importance if under-16 access to mainstream platforms is cut off. That would mark a significant shift for brands that have grown used to short-form video as the main route into youth culture.
Hayes argued that trying to work around the policy rather than adapt to it would carry reputational risk.
"The worst move would be trying to find loopholes. Using older creators to indirectly chase under-16 attention, leaning on family accounts without care, or pushing campaigns into harder-to-police spaces will create obvious reputational risk.
The smarter move is to rebuild the brief. Brands need clearer age data, safer creator selection, stronger parent-facing messaging and a proper plan beyond TikTok and Instagram. Youth influence will still exist, but the easy version of buying it through social feeds is ending," he said.
The likely outcome is a broader shift in the mix of talent used by advertisers. Creators and public figures with established credibility outside algorithm-led social feeds, including athletes, educators, broadcasters, entertainers and family-safe personalities, may become more attractive to brands seeking lower-risk ways to reach relevant audiences.
Hayes said the coming restrictions would expose weaknesses in campaign planning and measurement that have been tolerated in the market for years.
"This is a professionalisation moment for influencer marketing. The ban will expose weak briefs, weak audience checks and weak creator selection. Brands that take it seriously now will be in a stronger position when the rules come in.
This is not about brands abandoning youth culture. It is about proving they can reach the right audience in a way that is safer, clearer and easier to defend. The old brief was often 'find us reach'. The new brief will have to be 'show us who we are reaching, why they are appropriate and how the campaign stays safe'," he said.
