Short form video marketing: five UK creator ad checks

What to take away

Why CMA and ASA both matter for paid creator video

The CMA and the ASA police different things, and a single paid creator video can breach both regimes. The CMA protects consumers from unfair commercial practices, including hidden advertising. The ASA applies the CAP Code to ads in UK media, social platforms included.

The CMA's remit covers the commercial behaviour of businesses towards consumers. Its consumer protection guidance for businesses sets out how unfair commercial practices are treated, and undisclosed paid promotion is squarely within that territory.

The ASA approach is narrower but faster. The CAP Code requires ads to be obviously identifiable as ads, which is why an undisclosed paid partnership can be ruled against without any consumer losing money. The advertising codes are the text your creator brief should be checked against.

For compliance teams, the practical consequence is a two-track review. Legal checks the CMA side for unfair commercial practice risk, while marketing checks the CAP Code for recognisability and disclosure wording.

Regionally, the work concentrates where agency and in-house teams cluster, in Greater London, the North West, the West Midlands and Scotland. The rules are the same across all of them.

If your team is still building the basics, start with the short form video disclosure policy before drafting campaign-specific wording.

Rule one: ads must be recognisable as ads

The first rule is simple to state and easy to break: a paid creator video must be identifiable as advertising before a viewer engages with it. Not at the end. Not in a pinned comment nobody reads.

The CAP Code test is whether the ad is obviously identifiable. A brand name in the caption is not enough if the video reads as organic opinion. A gift with no conditions is usually not an ad; payment, free product with an agreed brief, affiliate commission or a commercial partnership usually is.

Placement matters. On TikTok and YouTube Shorts, the disclosure should appear in the video itself, in the first seconds, and in the caption. A viewer scrolling without sound should still register that this is paid promotion.

Wording should be plain. "Ad", "Advert" or "Paid partnership with [brand]" works. Vague labels such as "sp", "collab" or a bare brand tag do not.

Use the ASA's online affiliate marketing guidance when commission links, discount codes or affiliate relationships are involved, because those arrangements carry their own disclosure expectations.

A worked example

A Manchester skincare brand pays a creator £1,200 for three TikToks. The brief says "keep it authentic, no hard sell". The creator posts without a paid partnership label.

Under rule one, the videos are not recognisable as ads. The fix is not a disclaimer buried in the caption. It is a visible label in the first two seconds, a caption line naming the brand, and the platform's paid partnership toggle switched on.

Rule two: material connections must be disclosed clearly

The second rule covers anything that could affect how a viewer weighs a recommendation. That is a material connection, and it must be disclosed clearly.

Material connections include cash payment, free or discounted products, affiliate commission, gifted stays and long-term ambassador deals. The test is whether the connection could affect the weight a viewer gives the content.

Disclosure must be clear, prominent and in the same place as the claim. A single hashtag in a wall of tags fails. A verbal mention at minute eight of a ten-minute video fails.

Creators cannot contract out of this. A brief that says "do not mention the partnership" is itself a compliance problem, and agencies that issue such briefs carry risk alongside the brand.

Keep a written record of what was given, when, and how it was disclosed. If the ASA receives a complaint, that record is what you will rely on.

The short form video advertising rules set out how disclosure wording interacts with platform tools, which is worth reading alongside this section.

Rule three: claims and testimonials must be substantiated

The third rule is where marketing teams and legal teams most often disagree. Every factual claim in a paid creator video needs evidence held before publication.

Health, beauty, finance and supplement claims attract the most scrutiny. "Clinically proven", "boosts immunity" and "risk-free returns" need evidence that a reasonable person would accept, not a supplier's marketing deck.

Testimonials must be genuine. A scripted "real result" delivered by a paid creator is a testimonial, and it must reflect a genuine experience. Invented or exaggerated results are a breach.

Comparative claims are riskier still. "Better than [rival]" needs a like-for-like basis you can show on request.

The practical control is a claims log. Every factual statement in the brief gets a line, an evidence source and an owner. If a line cannot be evidenced, it comes out of the script.

This is also where UK GDPR and PECR sit. If a creator reads out customer data, or a campaign uses viewer data for retargeting, the Information Commissioner's Office guidance applies. Check UK ad disclosure and consent before approving anything that touches personal data.

Rule four: platform transparency centres and ad labelling

Platforms run their own ad policies on top of UK law, and the transparency centres are where those policies are published. YouTube, TikTok and Meta UK each maintain one.

These centres matter for two reasons. First, they show what labelling tools exist and how they are meant to be used. Second, they are evidence. A screenshot of the paid partnership toggle, the ad settings and the published label is a defensible record.

Ad labelling rules differ by platform. TikTok's branded content toggle, YouTube's paid promotion checkbox and Meta's paid partnership label all change how a post is treated and displayed. A creator brief should name the exact setting required.

Transparency centres also publish ad libraries and policy updates. Checking them quarterly keeps a compliance programme current without relying on second-hand summaries.

Keep the evidence file per campaign: label screenshots, disclosure wording, the signed brief and the claims log. For a fuller picture of the statutory background, the short form video UK regulations explain how platform policy sits under UK law.

Numbered steps: setting up a compliant paid post

Rule five: enforcement, sanctions and Trading Standards referrals

Enforcement escalates. The ASA publishes rulings and maintains a list of non-compliant online advertisers for those who keep breaching after a ruling.

Being named on that list has commercial consequences. Ad space can be withdrawn, paid search ads can be pulled, and partners may walk away. For a brand, that is often a bigger cost than the original ruling.

The CMA route is heavier. Where there is evidence of unfair commercial practices, the CMA can investigate and act, and it can refer matters to Trading Standards for enforcement. The CMA's role in consumer protection and competition enforcement is the starting point for understanding that escalation path.

Other regulators can join in. Ofcom covers video sharing platform duties, the ICO covers data protection, and HMRC cares about VAT and IR35 treatment of creator payments. A single campaign can touch all four.

Sanctions range from a published ruling and required undertakings to court action in serious cases. The cheapest response is always the one that never becomes a case.

Checklist: pre-publication compliance

Applying the five rules to a creator brief

A brief is where compliance is won or lost. If the disclosure requirement is not written into it, expect it to be missed.

Start with a one-page summary: what is being paid, what must be disclosed, where the label goes, which claims are approved, and what evidence is held. Attach it to every creator contract.

Then train the reviewers. The person approving final cut needs to know the recognisability test, not just the brand guidelines. Give them the checklist above and a named escalation contact.

Finally, review quarterly. Platform labelling tools change, transparency centres publish updates, and ASA guidance moves. A brief that was compliant last year may not be this year.
