ASA's Latest Warning: Is Your Influencer Marketing Truly Compliant?

Is Your Influencer Marketing Truly Compliant?

The Advertising Standards Authority (ASA) has once again shone a spotlight on influencer marketing transparency in the UK. On 9 May 2025, the ASA published its latest influencer ad disclosure report, scrutinising how well influencers are adhering to the rules on making their social media posts clearly identifiable as advertisements.

Using its advanced Artificial Intelligence (AI)-driven Active Ad Monitoring system, the ASA meticulously analysed over 50,000 social media posts from 509 UK accounts and 390 individual influencers across Instagram and TikTok. A representative sample was also manually assessed by ASA experts.

While the report indicated some improvement in ad disclosure rates since its last major study in 2021, the overall compliance level remains lower than the ASA expects. This signals a clear need for further, targeted enforcement action by the regulator. The ASA's findings are a clear call to action for brands. Don't risk your reputation or face regulatory scrutiny.

Critical Reminders for Brands and Influencers

The ASA's latest report is a crucial reminder that transparency in influencer marketing is non-negotiable. Beyond the statistics, the regulator re-emphasised several fundamental principles that all parties in the advertising supply chain—brands, influencers, and agencies—must adhere to. Compliance isn't just about avoiding sanctions; it's about building and maintaining consumer trust.

1. Shared Accountability: Everyone is on the Hook

A common misconception is that the burden of disclosure falls solely on the influencer. The ASA and CMA have consistently debunked this, making it unequivocally clear that all parties are equally accountable. Brands cannot outsource their legal responsibilities. This means:

• Brands' Due Diligence: Businesses must implement robust processes to ensure their influencers understand and adhere to UK advertising regulations. This includes providing clear guidelines, appropriate training, and regular monitoring.

• Agencies' Role: Marketing agencies facilitating campaigns also share responsibility for compliance. They should advise both brands and influencers on best practices and ensure contracts reflect these obligations.

• Influencer Responsibility: Influencers, as creators of the content, must actively ensure their commercial relationships are transparently communicated to their audience.

The ASA strongly advises using platform-specific ad disclosure tools (e.g., Instagram's "Paid Partnership" tag, TikTok's "Commercial Content Disclosure") in conjunction with other methods, as these tools can help automate and standardise disclosure.

2. "Ad" First and Foremost: Unambiguous Disclosure

The most critical takeaway is the demand for unambiguous and upfront disclosure. Ads must be "immediately identifiable as ads". This means:

• Prominent Placement: The disclosure, ideally "Ad" or "#Ad", must be at the very beginning of the social media post caption, visible without clicking "see more" or scrolling. It should also be clearly visible in video content (e.g., on-screen text, verbal mention at the start and periodically).

• Clear Language: Vague or subtle terms are no longer sufficient. Terms like "gifted," "PR trip," "supported by," "in association with," "spon," or "collab" do not adequately convey the commercial nature of the content on their own. While an influencer might want to specify the type of commercial relationship, the primary "Ad" label must always come first (e.g., "Ad – Gifted," "#ad – PR trip").

• Platform-Specific Nuances: While the general principles apply across platforms, brands and influencers should be aware of platform-specific features and best practices for disclosure (e.g., Instagram Stories disclosures overlaid directly on the visual, repeating verbal disclosures in live streams).

3. Disclosure on Every Piece of Content: No Shortcuts

Brands and influencers cannot rely on a single disclosure (e.g., in an influencer's bio, on their website, or in previous posts) to cover multiple pieces of advertising content. Each individual piece of advertising content – whether a photo, Reel, Story, TikTok video, or a carousel post – must be clearly and distinctly disclosed as an ad. This includes content where an influencer is earning a commission via affiliate links; those specific links and the commercial nature of the content around them need to be disclosed.

4. Own Brand Content: The Nuance of Personal Promotion

When an influencer is promoting their own brand or products, the rules can be slightly nuanced. The ASA may deem disclosure "clear by context" if the content unequivocally states that the influencer is promoting their own business. For example, if the brand name matches the influencer's account name, it might be considered clearer.

However, if there's any potential for ambiguity, or if the brand name isn't immediately associated with the influencer, an explicit "Ad" disclosure is still strongly recommended to avoid misleading consumers. This ensures that followers clearly understand when an influencer is acting in a commercial capacity for their own venture, rather than giving an unbiased personal opinion.

By understanding and rigorously applying these fundamental principles, brands can proactively mitigate regulatory risks, build stronger consumer trust, and ensure their influencer marketing campaigns are not just impactful, but also fully compliant with UK advertising standards. The world of UK influencer marketing and advertising regulations is constantly evolving. Staying informed is crucial for safeguarding your brand.

Why This Matters to Your Brand: Increased Scrutiny and Evolving Landscape

The issue of influencer ad disclosure is not confined to the UK; it's a critical, high-priority concern for regulators worldwide. The European Commission’s "fitness check" of EU consumer law has repeatedly highlighted a pervasive lack of transparency in social selling and influencer marketing as a significant problem. This global push for transparency is culminating in new legislation like the upcoming Digital Fairness Act, expected mid-2026, which will introduce even tougher oversight and clearer definitions for commercial relationships in digital marketing.

The ASA's recent report, published in May 2025, while showing some slight improvement, underscores that compliance levels remain unsatisfactory. This signals a clear escalation in the ASA's commitment to enforcement. Coupled with the CMA’s significantly enhanced enforcement powers under the Digital Markets, Competition and Consumers Act (DMCC) 2024, UK brands face unprecedented risks for non-compliance. These risks now include:

• Public Rulings and "Name and Shame" Campaigns: The ASA regularly publishes detailed rulings on its website, publicly naming both non-compliant brands and influencers. This acts as a powerful deterrent, damaging reputations and eroding consumer trust. The ASA has also demonstrated its willingness to run targeted ads against persistent rule-breaking influencers, directly informing their audience of non-compliance.

• Severe Reputational Damage: Beyond formal rulings, social media backlash and negative press from undisclosed or misleading content can cause irreparable harm to your brand image. In an age where authenticity is paramount, transparency failures can quickly lead to widespread consumer distrust and a decline in brand loyalty.

• CMA Investigations and Substantial Fines: Under the DMCC Act 2024, which came into force in April 2025, the CMA now has direct powers to impose significant financial penalties without needing a court order. For serious or persistent breaches of consumer protection law (including misleading advertising and hidden ads), businesses can face fines of up to 10% of their annual global turnover or a fixed penalty of up to £300,000, whichever is higher. Daily fines for continued non-compliance can also be imposed. This represents a monumental shift, making proactive compliance absolutely essential.

• Legal Action and Individual Accountability: Persistent non-compliance can lead to legal proceedings, and importantly, individuals within a company (such as directors or senior executives) can be held personally liable for breaches, potentially facing fines or even criminal prosecution in severe cases.

The ASA's increasing focus on "intermediary parties" in the advertising supply chain—which critically includes influencers, but also extends to platforms and agencies—further underscores the urgent need for brands to have robust compliance systems and legally sound influencer marketing agreements in place. It's no longer sufficient to simply brief an influencer; brands must actively monitor and enforce compliance.

Don't wait for a complaint or a formal investigation to act. Proactive compliance is your brand's strongest defence against these escalating regulatory pressures and the associated financial and reputational fallout.

Influencer Marketing Legal FAQs

1. What does the ASA's latest influencer ad disclosure report mean for UK brands?

The ASA's May 2025 report analysed over 50,000 posts from 509 UK accounts and found that compliance rates remain below the regulator's expectations. For brands, the practical implication is straightforward: the ASA is actively monitoring at scale using AI-driven systems, and non-compliant posts are being identified faster than ever. Brands cannot rely on influencers to self-police. You need contractual compliance obligations, a pre-publication approval process, and a monitoring system in place before a campaign goes live.

2. Are brands legally responsible if an influencer fails to disclose a paid post?

Yes. The ASA and CMA have both confirmed that brands share equal responsibility for non-disclosure, not just the influencer. If you paid for the promotion, you are on the hook for ensuring it is properly labelled. This applies regardless of whether the influencer forgot, used ambiguous language, or buried the disclosure in hashtags. Your influencer marketing agreement must include an explicit obligation to disclose, a content approval process, and a take-down clause if the post does not meet CAP Code standards.

3. Is "gifted" or "PR trip" enough to disclose a paid partnership in the UK?

No. Terms like "gifted," "PR trip," "supported by," "in association with," "spon," or "collab" are not sufficient on their own. The ASA requires that advertising is obvious and apparent from the moment a user sees the post, without clicking "see more" or scrolling. The only labels the ASA consistently accepts as adequate are "Ad" or "#Ad," placed at the very start of the caption. If an influencer wants to specify the nature of the arrangement, the "Ad" label must still come first, for example "Ad, gifted" or "#Ad, PR trip."

4. Does disclosure need to appear on every post in a campaign?

Yes, every single piece of content requires its own disclosure. A brand cannot rely on a previous post, a bio disclosure, or a website disclaimer to cover multiple pieces of advertising content. Every photo, Reel, Story, TikTok video, carousel, and affiliate link post must be individually and clearly labelled as an ad. This includes content where the influencer earns a commission through affiliate links. Each post is assessed on a standalone basis by the ASA.

5. What fines can UK brands face for influencer marketing non-compliance?

There are two levels of consequence. First, reputational: the ASA publishes rulings publicly, naming both the brand and the influencer. Appearing on the ASA's non-compliant advertisers list causes lasting damage. Second, financial: under the Digital Markets, Competition and Consumers Act 2024, which came into force in April 2025, the CMA can now impose fines of up to 10% of annual global turnover or a fixed penalty of up to £300,000, whichever is higher, without needing a court order. Daily fines apply for continued non-compliance. In the most serious cases, individuals within the brand, including directors, can face personal liability.

6. What are the ASA rules on influencer disclosure for Instagram Stories and TikTok videos?

The same core principle applies across all formats: the disclosure must be immediately visible. For Instagram Stories, "Ad" or "#Ad" must be overlaid directly on the visual, not placed on a separate slide. For TikTok videos, a verbal disclosure at the start of the video is required alongside the on-screen label, particularly for longer content. The platform-native disclosure tools, such as Instagram's "Paid Partnership" tag and TikTok's "Commercial Content Disclosure," are recommended by the ASA but do not replace the need for a clear "Ad" label in the caption or on-screen text.

7. Do UK influencer advertising rules apply to influencers based outside the UK?

Yes, if the content targets a UK audience. The ASA and CMA can take action against non-UK influencers and brands where content is directed at UK consumers. The FCA's rules are even more explicit: financial promotions made outside the UK are subject to UK rules if they are capable of having an effect within the UK. A brand cannot avoid its compliance obligations simply by working with an overseas influencer. Your agreement must extend compliance obligations to all influencers on a campaign regardless of where they are based.

8. What is the FCA's role in influencer marketing and who does it affect?

The FCA regulates financial promotions, which includes content promoting investment products, trading platforms, buy now pay later services, and cryptocurrency. Under the Financial Services and Markets Act 2000, it is a criminal offence to communicate a financial promotion unless it has been approved by an FCA-authorised person. This applies to influencer content in the same way it applies to any other advertisement. Brands in regulated sectors must ensure that every piece of influencer content promoting a financial product is pre-approved by an FCA-authorised entity before publication. The consequences of getting this wrong include unlimited fines and up to two years' imprisonment.

9. What should brands do right now to ensure influencer marketing compliance?

Three immediate steps. First, audit your existing influencer agreements to check they include explicit CAP Code compliance obligations, a pre-publication approval clause, and a take-down right. Second, brief all active influencers on current ASA disclosure requirements, specifically the "Ad first" rule, and document that briefing. Third, implement a monitoring process to check published content against your approved brief before and after it goes live. If a post is flagged in an ASA investigation, documented evidence of your own compliance process significantly reduces your exposure.

10. What is the Digital Markets, Competition and Consumers Act 2024 and why does it matter for influencer marketing?

The DMCC Act came into force in April 2025 and significantly upgraded the CMA's enforcement powers in consumer protection. Previously, the CMA needed a court order to impose fines. It can now act directly, imposing penalties of up to 10% of global annual turnover for consumer protection breaches. For influencer marketing, this means undisclosed ads and misleading content are no longer just a reputational risk; they carry a direct and substantial financial penalty. The Act represents the most significant shift in UK consumer protection enforcement in years and makes robust influencer agreements more important than ever.
