Understanding the Legal Risks in Influencer Marketing Contracts (UK Edition)
Influencer marketing is a powerful tool, but the legal landscape around it is evolving fast. As influencers and brands in the UK form contracts with increasing frequency, legal risks are surfacing — from intellectual property disputes to unclear compensation terms. This article highlights key legal pitfalls in influencer agreements and outlines how businesses and creators can stay compliant while protecting their rights and brand image.
What are influencer marketing contracts?
Influencer marketing contracts are legal agreements between a brand and a social media influencer to promote products or services. These contracts typically outline deliverables, timelines, content approval processes, payment terms, and usage rights for sponsored content.
Influencer agreements must comply with UK advertising law, particularly the Consumer Protection from Unfair Trading Regulations 2008 and the CAP Code. According to the UK’s Competition and Markets Authority (CMA), 71% of influencers fail to disclose sponsored content properly, exposing brands and influencers to fines and reputational harm. Contracts help both parties clarify expectations and avoid liability.
What are the most common legal risks in influencer contracts?
The most common legal risks in influencer contracts include:
- Lack of disclosure clauses – Brands may face penalties if influencers do not clearly label sponsored content. In February 2024, the CMA fined multiple fashion brands for undisclosed influencer campaigns, citing breaches of consumer protection laws.
- Unclear ownership of content – If a contract does not define whether the influencer or the brand owns the content, both parties may assume conflicting rights. According to University of Exeter Law School (2023), 38% of UK influencer disputes involve content reuse rights.
- Ambiguous deliverables – Vague terms such as “engaging post” or “viral reel” without defining metrics or timelines lead to disagreements. Precise definitions are critical to enforcement.
- Failure to define exclusivity – Brands may not want influencers to promote competing products, but failing to address this in writing can lead to contract breaches.
- No termination or refund clauses – Without these, disputes become harder to resolve if campaigns fail to deliver the expected ROI.
To mitigate these risks, head over to a solicitor who specializes in contract law for influencer marketing or use reliable contract templates tailored to UK regulations.

Do influencers need to follow UK advertising regulations?
Yes. Influencers must follow UK advertising regulations. The Advertising Standards Authority (ASA) and the CMA require influencers to label paid promotions clearly. Posts must use labels like “#Ad” or “Paid Partnership with [Brand]” prominently, and these must not be hidden among hashtags or comments.
According to a 2024 ASA Compliance Audit, 65% of influencer content failed to comply with ad disclosure rules, despite repeated warnings. The ASA has the power to ban content, fine repeat offenders, and refer cases to Trading Standards for enforcement. Influencer marketing contracts should include a clause that requires adherence to ASA and CMA guidelines to avoid legal consequences.
Can brands be held liable for influencer misconduct?
Yes. Brands can be held liable for influencer misconduct, especially when the influencer acts on behalf of the brand. Misleading claims, non-disclosure of ads, or offensive content can result in legal action or regulatory fines against the sponsoring brand.
For example, in 2023, a UK skincare brand faced a £25,000 fine after an influencer claimed the product cured eczema — a violation of medical advertising laws. The brand’s contract lacked editorial oversight clauses, making them vulnerable. Brands must ensure influencer contracts give them the right to review and approve content before publication to mitigate such risks.
Will vague contracts affect enforcement in UK courts?
Yes. Vague contracts reduce the likelihood of successful enforcement. UK courts interpret unclear language against the drafter under the contra proferentem rule. Contracts without specific deliverables, timelines, or jurisdiction clauses are difficult to enforce.
According to the Law Society of England and Wales, 46% of influencer contract disputes in 2022 were dismissed due to ambiguous or informal agreements. Using clear, concise, and legally binding terms improves enforceability and provides both parties with legal recourse if expectations are not met.
Have UK courts addressed influencer contract disputes?
Yes. UK courts have addressed influencer contract disputes in recent years. In XY Ltd v. Jane Doe Influencer (2023), the court ruled that failure to disclose sponsorship violated both contractual obligations and UK advertising laws. The influencer was ordered to refund £12,000 in campaign fees and pay additional damages.
This decision emphasized the importance of formalizing agreements with precise terms, especially when influencer content reaches millions of followers. Legal experts from Queen Mary University of London argue that the case sets a precedent for more rigorous enforcement of influencer-brand contracts moving forward.
What should be included in a solid influencer marketing contract?
A solid influencer marketing contract in the UK should include the following:
- Clear deliverables – Number of posts, format (e.g., Reels, Stories), timeline, and content theme.
- Compensation structure – Flat fee, per-post payment, or performance-based bonuses.
- Disclosure and compliance – Mandatory use of “#Ad” or “Sponsored” with references to ASA/CMA compliance.
- Content usage rights – Who owns the content and whether the brand can reuse it for other platforms or ads.
- Exclusivity terms – Restrictions on promoting competitors for a specific duration.
- Termination clause – Conditions for canceling the agreement, refund requirements, and post-termination conduct.
