Whether you’re just starting or already earning online, we’ll guide you with simple, honest advice tailored to your situation so you can focus on what you do best.
Introduction
In today’s digital age, influencer marketing has revolutionised the way brands connect with their audiences. However, with this growth comes the need for clear rules to protect consumers and ensure fair practices. In the UK, the Competition and Markets Authority (CMA) plays a critical role in regulating marketing activities to maintain transparency and fairness. Understanding CMA’s role in fair marketing is essential for influencers who want to avoid legal pitfalls, build trust, and foster long-term success.
What is the CMA?
The Competition and Markets Authority (CMA) is a UK government body tasked with promoting competition and ensuring that markets work fairly for consumers, businesses, and the economy. In marketing, the CMA enforces regulations to prevent misleading or deceptive practices, ensuring that advertisements are transparent and honest. For influencers, this means adhering to rules about disclosure, accuracy, and honesty in promotional content. Breaching these guidelines can lead to investigations, penalties, and reputational damage.
The Digital Markets, Competition and Consumers Act 2024
A significant development in UK consumer protection law came into effect on 6 April 2025 with the Digital Markets, Competition and Consumers Act 2024 (DMCCA). This legislation largely repeals and replaces the Consumer Protection from Unfair Trading Regulations 2008, introducing stricter rules and significantly enhanced enforcement powers for the CMA . Under the DMCCA, the CMA can now impose fines of up to 10% of a company’s annual global turnover for breaches of consumer law .
Why CMA’s Role in Fair Marketing Matters for Influencers
The CMA’s primary focus in influencer marketing is to protect consumers from misleading or unfair practices. As influencers often share personal experiences and recommendations, their audience trusts their opinions. This trust makes it crucial for influencers to operate with complete transparency. Without proper adherence to CMA rules, influencers risk facing penalties, including:
Formal warnings from the CMA. Legal actions, which can result in fines or restrictions. Loss of credibility with followers and brands.
Moreover, failing to comply with CMA guidelines can harm the influencer marketing industry as a whole, leading to stricter regulations and reduced opportunities.
Key Principles of CMA’s Role in Fair Marketing
To ensure fair marketing practices, the CMA focuses on these key principles:
1. Transparent Advertising
The CMA mandates that influencers disclose when their content is promotional. For instance, if a post is sponsored or involves a material connection with a brand, it must be clearly stated. Ambiguity in such cases can mislead consumers and violate CMA guidelines. The CMA has updated its guidance for content creators, emphasising that all forms of incentivised content must be clearly and prominently identified as advertising .
2. Honest and Accurate Claims
All claims made in promotional content must be truthful and supported by evidence. For example, stating that a fitness supplement will “double energy levels” without scientific proof is a direct breach of the CMA’s standards. The CMA’s Green Claims Code also requires that environmental claims are clear, accurate, and not misleading .
3. Avoiding Exploitation of Trust
Influencers must not misuse the trust their followers place in them. For example, promoting products they haven’t used or don’t believe in can lead to accusations of dishonesty.
Common Scenarios Where Influencers Breach CMA Guidelines
Understanding CMA’s role in fair marketing involves recognising common mistakes influencers make, such as:
Failing to Disclose Sponsored Content
Not labelling paid collaborations clearly, such as by using ambiguous terms like #partner or #collab, is a frequent mistake. The CMA requires clear terms like #ad or #sponsored to ensure transparency. The joint CMA/ASA guidance explicitly states that vague labels such as “collab”, “spon”, or simply tagging a brand are not sufficient .
Making Unsupported Product Claims
Claims about a product’s effectiveness must be backed by reliable evidence. For example, saying “This cream eliminates wrinkles in 7 days” without scientific proof can lead to CMA investigations.
Hiding Material Connections
Even non-paid collaborations, such as receiving free products, count as material connections and must be disclosed to the audience. The CMA has clarified that any form of incentive or reward—including money, commissions, discounts, or gifts—constitutes payment and requires disclosure .
How Influencers Can Stay Compliant
To align with CMA’s role in fair marketing, influencers should take proactive steps to ensure compliance. Here’s how:
1. Clearly Disclose Paid Relationships
Every sponsored post, whether paid or gifted, must include clear labels like #ad or #sponsored. Place these disclosures prominently, ideally at the beginning of captions, so they’re noticeable to all viewers. Disclosures must be immediate and prominent—not hidden in hashtags or “see more” sections . Using ambiguous terms like ‘#gift’ or ‘#collab’ should be avoided .
2. Be Honest in Promotions
Only make claims that are factual and verifiable. For example, if promoting a health product, ensure that claims are supported by credible data from the brand or scientific studies.
3. Familiarise Yourself with CMA Guidelines
The CMA frequently updates its rules to address new trends in marketing. Regularly reviewing these updates ensures that your practices stay compliant. The CMA has published specific guidance for content creators, which applies not only to formal agreements with brands but also to informal arrangements, including posting about gifts or freebies .
4. Work with Ethical Brands
Collaborate with brands that respect CMA regulations and provide clear guidelines for disclosures and evidence-based claims. Brands also have a responsibility to ensure that content promoting their products is properly labelled as advertising .
5. Seek Expert Advice
If unsure about the compliance of a campaign, consult legal experts or marketing professionals familiar with CMA regulations.
How CMA Enforcement Works
The CMA actively monitors the marketing space and investigates potential breaches. For instance:
They may review social media posts to identify hidden advertisements or misleading claims. Influencers or brands can be flagged by consumer complaints. Repeat offenders face stricter actions, including public reprimands or legal consequences.
Enhanced Enforcement Powers
From 6 April 2025, the CMA can directly investigate and enforce against businesses for non-compliance without needing to obtain a court order . The CMA can impose:
Monetary penalties of up to 10% of a company’s annual global turnover. Directions as to the business’s future conduct. Enhanced consumer protection measures, including redress for consumers .
Fake Reviews Prohibition
A key focus of the DMCCA is the prohibition of fake and misleading reviews. The CMA has published standalone guidance on fake reviews, which prohibits submitting, commissioning, or facilitating the submission of fake or misleading reviews. It also requires platforms to take “reasonable and proportionate steps” to prevent the publication of fake reviews .
The Broader Impact of CMA’s Role in Fair Marketing
The CMA’s regulations aim to create a balanced marketing ecosystem that benefits both consumers and influencers. For influencers, compliance is not just a legal requirement; it’s an opportunity to build lasting trust with their audience. Transparency, honesty, and ethical practices strengthen relationships with followers and enhance brand partnerships. Moreover, influencers who align with CMA’s role in fair marketing contribute to the credibility and sustainability of the industry. Ethical marketing practices ensure that the influencer marketing space remains a valuable and respected part of modern advertising.
Avoid last-minute surprises by seeing your costs upfront, so you can plan better, stay in control, and make smarter financial decisions.
Conclusion
The CMA is at the forefront of ensuring fairness and transparency in influencer marketing. For influencers, understanding CMA’s role in fair marketing is not just about avoiding penalties but also about fostering trust, credibility, and sustainable growth. By adhering to CMA guidelines, influencers can safeguard their reputations, maintain strong connections with their audience, and continue thriving in a rapidly evolving digital landscape. Ethical marketing isn’t just a requirement—it’s the foundation of a successful influencer career.
