ASA CAP Code Influencer Disclosure: What Brands Get Wrong

The ASA CAP Code influencer marketing disclosure rules require that any content where a brand has paid, gifted, or exercised editorial control must be clearly labelled as an advertisement. That means #ad, not #gifted, not #collab, and not buried in a list of twenty other hashtags. The rules apply whether the influencer received cash, free product, or a loan, and whether the content appears on Instagram, TikTok, YouTube, or a podcast.

Most brands know this in principle. Most brands still get it wrong in practice, usually because they have not built the disclosure requirement into their influencer workflow from the start.

I have been inside enough agency briefing rooms to know that influencer compliance is usually treated as an afterthought. The campaign gets planned, the influencers get briefed, the content goes live, and then someone in legal asks whether everything was disclosed correctly. That sequence is backwards, and it is the source of most of the problems brands run into.

What the CAP Code Actually Says

The Committee of Advertising Practice (CAP) Code is the rulebook that governs non-broadcast advertising in the UK. The ASA enforces it. For influencer content, the relevant sections sit under the broader principle that marketing communications must be obviously identifiable as such.

The specific trigger for disclosure is commercial intent combined with brand control. If a brand has paid an influencer, provided free product, or exercised any editorial input over the content, including approving scripts, requesting specific claims, or having the right to veto, the content is a marketing communication and must be labelled accordingly.

What counts as editorial control is broader than most brands assume. You do not need to have written the script. If you sent a brief, provided talking points, asked for certain products to be featured, or reviewed the content before it went live, that is likely enough to constitute control. The ASA has been explicit on this point in multiple rulings.

The CAP Code also makes clear that the obligation is not satisfied by disclosure that is easy to miss. The label must appear before the audience engages with the content. On Instagram, that means before the “more” truncation. On YouTube, it must appear in the video itself, not just in the description. On TikTok, it must be visible before the viewer has to take any action to see it.

If you want a broader grounding in how influencer marketing is structured commercially before getting into the compliance detail, the influencer marketing hub covers the full picture, from strategy through to execution and measurement.

The Gifting Problem That Most Brands Have Not Solved

Gifting is where the compliance conversation gets complicated, and where I see the most casual non-compliance from otherwise careful brands.

The assumption many brands operate under is that gifting sits in a grey area. They send product, the influencer posts if they want to, there is no formal agreement, so surely it is just organic content? The ASA has been clear that this reasoning does not hold when there is an expectation of coverage, even an implicit one.

If you are sending product to influencers with any expectation that they will post about it, that content needs to be disclosed. If you are sending product with no expectation of coverage and genuinely no editorial input, and the influencer then chooses to post entirely on their own initiative, that is a different situation. But most gifting programmes do not work that way. There is usually an outreach email, a brief, a hashtag suggestion, or a follow-up asking when the content will go live. Each of those elements moves the content closer to the disclosure threshold.

I wrote about the mechanics of running gifting programmes in the piece on influencer marketing remote gifting, which covers the operational side. The compliance dimension is worth treating separately because it requires a different kind of rigour.

The label that causes the most confusion is #gifted. Many influencers use it in good faith, believing it satisfies the requirement. It does not. The ASA has ruled that #gifted is ambiguous because it does not clearly communicate that the content is an advertisement. Audiences may not understand that gifted product creates a commercial relationship. Only #ad, or similarly unambiguous labels like “Advertisement” or “Paid partnership with [Brand]”, satisfy the requirement.

Where Affiliate Arrangements Sit

Affiliate marketing through influencers is a different commercial model but carries the same disclosure obligation. If an influencer earns commission from sales generated through their content, that content is a marketing communication and must be labelled as such.

This catches a lot of brands off guard because affiliate arrangements often feel more arm’s length. The influencer is not being paid upfront. They are not being briefed in the traditional sense. But the commercial incentive is still there, and the ASA’s position is that audiences have a right to know when a recommendation is financially motivated.

The practical implication is that any influencer running your affiliate links needs to understand their disclosure obligations and apply them consistently. That means including this requirement in your affiliate terms, not just your paid partnership contracts.

Understanding what the premise behind influencer marketing actually is helps here. The entire model is built on the trust audiences place in creators. Disclosure does not undermine that trust. Undisclosed commercial content does, when it eventually comes out, and it usually does.

Liability: Who Is Actually Responsible

Both the brand and the influencer carry liability under the CAP Code. The ASA can and does take action against both parties. This matters because some brands operate as if they can outsource compliance to the creator, include a disclosure clause in the contract, and consider their obligations discharged.

That is not how it works. If you are the advertiser, you are responsible for ensuring the content that promotes your brand is properly disclosed. A contract clause helps, but it does not transfer your liability. If the content goes live without proper disclosure, your brand is implicated regardless of what the contract says.

I have spent time on both sides of this, working with brands that wanted to run influencer programmes at scale and with agencies managing the execution. The brands that handled compliance well treated it as a shared responsibility. They built disclosure requirements into briefs, checked content before it went live, and had a clear escalation path when something was posted incorrectly. The brands that had problems were the ones that issued a contract, assumed the influencer would handle it, and only looked at the content after it was already live.

From a practical standpoint, this means your influencer contracts need to specify the exact disclosure label required, the placement of that label, and the consequences of non-compliance. It also means your approval process, if you have one, needs to include a disclosure check before content is approved to go live.

Platform-Specific Disclosure Mechanics

The ASA’s rules are platform-agnostic in principle, but the practical application varies by platform because the content formats are different. Getting this right means understanding how disclosure works on each platform your influencer programme touches.

On Instagram, the disclosure must appear in the caption before the “more” truncation, or as an overlay on Stories content. Instagram’s own “Paid partnership” label satisfies the requirement, but only if the brand account is tagged correctly and the label is actually visible. Some influencers use the paid partnership label but tag the wrong account or apply it inconsistently. That is worth checking.

On TikTok, the platform has a built-in branded content toggle that generates a disclosure label. Using it is the cleanest approach. If an influencer is not using it, the disclosure needs to appear in the video itself or in the caption before truncation.

On YouTube, the ASA expects disclosure in the video itself, not just in the description. A verbal disclosure at the start of the video, combined with an on-screen label, is the approach that holds up. YouTube’s own paid promotion checkbox is a baseline, but it does not replace the requirement for clear disclosure within the content.

Podcasts are an area where disclosure practice is still inconsistent. The ASA’s position is that sponsored segments need to be clearly identified as such at the point they occur in the episode, not just in the show notes.

If you are running influencer programmes across multiple platforms, tools that help you monitor content at scale become more important. Social listening for influencer marketing can surface content that has gone live without proper disclosure before it becomes a formal complaint.

Building Compliance Into the Workflow, Not Onto It

The brands that consistently get disclosure right are not the ones with the most detailed legal disclaimers in their contracts. They are the ones that have built disclosure into the operational workflow so that it cannot be missed.

That means the brief includes the exact disclosure label and placement requirement. The content approval checklist includes a disclosure check. The post-live review includes a disclosure audit. And the influencer onboarding process includes a plain-English explanation of what is required and why, not just a reference to the CAP Code.

Early in my career, I learned that the difference between a process that works and one that looks good on paper is whether the people executing it actually understand the reason behind it. Influencer disclosure is the same. If an influencer understands that undisclosed commercial content erodes audience trust, and that audience trust is the entire basis of their commercial value, they are far more likely to apply disclosure consistently than if they have just been told to put #ad in the caption because the contract says so.

For brands running retail-focused influencer programmes, where the volume of content and the number of influencers involved can be significant, the operational challenge is real. The piece on influencer marketing in retail covers some of the scale considerations, and compliance needs to be part of that picture from the start.

Micro-influencer programmes create a particular challenge because the volume of creators involved makes manual oversight difficult. HubSpot’s breakdown of micro-influencer marketing covers why smaller creators drive strong engagement, but the compliance obligation is identical regardless of follower count. A creator with 5,000 followers posting undisclosed commercial content is just as much a CAP Code breach as one with 500,000.

What the ASA Enforcement Record Actually Shows

The ASA publishes its rulings, and the influencer disclosure cases are instructive. A consistent pattern runs through them: the content was not obviously identifiable as an advertisement, the disclosure was present but not prominent enough, or the brand believed the influencer had handled it when they had not.

The ASA has ruled against major brands and well-known influencers. The cases are public. The reputational damage from appearing in an ASA ruling is real, particularly for brands that have invested in positioning themselves as authentic or values-led. There is a particular irony in a brand being found to have run undisclosed advertising through an influencer whose appeal is built on authenticity.

The ASA also runs proactive monitoring exercises, where it sweeps specific sectors or platforms for non-compliant influencer content. These sweeps have targeted fashion, beauty, food and drink, and financial services. If your brand operates in a high-profile consumer sector, the probability of your influencer content being reviewed at some point is not negligible.

For start-ups building influencer programmes from scratch, the temptation is to move fast and sort the compliance detail later. That is a false economy. Getting the disclosure framework right from the start costs very little. Getting it wrong, and having to manage an ASA complaint while also managing a brand crisis, costs considerably more. The piece on influencer marketing for start-ups covers the broader strategic considerations, but compliance is not a scale-up problem. It is a day-one problem.

Resources like Buffer’s influencer marketing overview and Later’s influencer marketing glossary provide useful context on how the industry operates commercially, which helps frame why the regulatory framework exists in the first place. The ASA rules are not arbitrary. They exist because undisclosed advertising undermines the consumer’s ability to make informed decisions, and because the influencer industry grew fast enough that self-regulation was not keeping pace.

UGC and the Disclosure Question

User-generated content sits at an interesting intersection with disclosure rules. If a consumer creates content about your brand entirely independently, with no commercial relationship and no editorial input from you, that content does not require disclosure. But when brands use UGC in paid advertising, or when they commission content that is designed to look like organic UGC, the disclosure obligation applies.

Commissioned UGC, where a brand pays a creator to produce content in a realistic, unpolished style for use in paid social ads, is a marketing communication. If it appears in a paid placement, the platform’s ad labelling handles the disclosure. But if that same content is reposted organically through a brand account or through the creator’s own channel, it needs to be disclosed as commercial content.

If you are using software to manage UGC content at scale, the comparison of UGC video software for social media advertising covers the tools available, and disclosure workflow is worth checking as a feature criterion when you are evaluating platforms.

The broader influencer marketing landscape, from strategy and creator selection through to measurement and compliance, is covered across the influencer marketing hub. Disclosure is one piece of a larger operational picture, but it is the piece most likely to create regulatory exposure if it is not handled correctly.

The Practical Checklist for Disclosure Compliance

Translating the CAP Code requirements into day-to-day practice comes down to a small number of consistent behaviours applied across every campaign.

First, define the disclosure label in the brief. Do not leave it to the influencer to decide. Specify #ad, or “Advertisement”, or the platform’s built-in paid partnership label, and specify exactly where it must appear in the content.

Second, include disclosure compliance in your content approval process. If you review content before it goes live, add a disclosure check to that review. If you do not review content before it goes live, consider whether that is a risk you are comfortable with.

Third, audit live content. Check that the disclosure appears as required after the content is posted. Influencers sometimes edit captions after posting, and disclosure labels can disappear in that process.

Fourth, include disclosure requirements in your contracts with enough specificity that a non-compliance clause is enforceable. Vague language about “complying with applicable regulations” is not the same as specifying the exact label, placement, and consequences of non-compliance.

Fifth, brief your influencers on the why, not just the what. Creators who understand the rationale apply the rules more consistently than those who see it as an administrative requirement imposed by the brand.

The measurement side of influencer marketing, including how to assess whether your campaigns are actually driving commercial outcomes, is worth reading alongside the compliance framework. Later’s guide to influencer marketing conversion covers how to connect influencer activity to measurable results, which is the commercial case for running these programmes properly in the first place. HubSpot’s analysis of whether influencer marketing works provides a useful reality check on where the channel delivers and where it does not.

Running compliant influencer programmes is not a constraint on effectiveness. The brands that treat disclosure as a genuine commitment to their audience, rather than a box to tick, tend to build influencer programmes that perform better over time. Audiences are not naive. They know commercial content exists. What erodes trust is the attempt to disguise it.
