Influencer marketing law is complex. The rules vary from country to country, frequently shift, and sometimes leave room for interpretation. However, staying compliant is more important than ever as the industry matures and consequences grow.
In this article, we’ll help you gain clarity by breaking down the current regulations. We'll also dive into how brands are responding to regulations and the ethical concerns around influencer marketing.

While influential celebrities have long been featured on billboards and TV ads, the options for brands are now more diverse. They can employ influencers who, like celebrities, form relationships with their audiences. Credibility, trustworthiness, and homophily (the similarity between followers and influencers) are the basis for these connections. And these bonds matter–for better or worse, studies show that influencers can even impact how people vote.
Influencers also impact their audience's purchasing habits. 25% of all consumers and 50% of Gen Z have bought products based on influencer recommendations. And what's more, 53% of marketing teams who rate themselves as "effective" invest in influencer campaigns.
But with this great power comes great responsibility–and legislation. Influencer marketing is now an established and regulated industry with laws designed to protect influencers, brands, and consumers.
Influencer marketing regulations are more stringent than ever, but are UK brands keeping up? And do they require influencers to adhere to any social or corporate ethics?
Looking for answers to these questions, Kolsquare conducted a survey with NewtonX, The Kolsquare State of Influencer Report was sent to over 380+ brands across France, Italy, Spain, Germany, and the UK.
The survey discovered that:
Overall, UK brands are careful about adhering to regulations and maintaining their brand image. However, the results also reveal an indifference towards ethics:
This paints a complex picture. Let's explore the data further.
That said, ethical considerations are not entirely absent from influencer selection criteria. A 2024 report by Kolsquare found that 43% of marketers prioritise ethical conduct and transparency or integrity when choosing influencers to work with. This suggests that while ethics may not always be formalised through strict charters or contractual obligations, a significant share of marketers still factor trust, credibility, and responsible behaviour into their decision-making. The challenge for UK brands, then, may not be a lack of awareness around ethics, but rather the difficulty of translating these values into clear frameworks and enforceable standards within influencer partnerships.

Although 73% of UK brands believe it’s crucial for influencer campaigns to reflect positively on their brands, many don’t require influencers to strictly adhere to their corporate ethics or values.
This lax approach may be because UK companies choose more casual campaign types, such as gifting and affiliate marketing, than other European brands. The Kolsquare report found that 46% of UK brands leverage gifting, while 53% use affiliate campaigns.
These models give influencers creative freedom and tend to be more hands-off than fixed-fee campaigns. While this approach to working with influencers often results in authentic content, it can make it difficult for brands to enforce adherence to corporate ethics. This could be the cause of the UK's more flexible approach to value alignment.
Regulations vary across Europe. The EU has increasingly taken harsher stances on IM and social media due to concerns about lowering attention spans and their effect on children. In 2024, the EU rejected TikTok’s new offering, TikTok Lite, after a “diligent assessment of the risks it entails.” The EU committee decided that TikTok did not have “effective risk mitigating measures” for their new, highly addictive app.
TikTok has halted the European release of its new app before it reached the UK. But let's dive into the current UK regulations and legislation.
The two main regulatory bodies in the UK are the Advertising Standards Authority (ASA) and the Competition and Markets Authority (CMA). Influencer marketing in the UK falls also falls under the Consumer Protection from Unfair Trading Regulations 2008 and the UK Code of Non-broadcast Advertising and Direct & Promotional Marketing (CAP).
These bodies enforce the following rules:
The UK government plans to give the CMA more power to independently determine breaches and issue fines. However, at the moment, the only punishment for failure to comply is “naming and shaming.”
Yes, influencers in the UK must disclose ads by clearly labelling posts as #ad, #sponsored, or similar terms when they receive payment, free products, or any other form of compensation.
If you're working with influencers abroad, you must also comply with the legislation in their country.
The UK regulations aren't just for show, they are actively enforced. For example, Love Island contestant Francesca Allen was "named and shamed” for repeatedly failing to disclose ad content.
Some argue that these "shaming" tactics aren't sufficiently effective, but there are still no fines in the UK for disobeying parties. However, the ASA believes that the negative publicity generated by a complaint may produce enough bad press in the short term to promote compliance. The brand's failure to adhere to regulations may also be the first thing shoppers see on search results.
Across Europe, legislation varies and can be tougher. For example, in France, failure to tag promotional posts can lead to fines and penalties of up to €300,000.
The European Commission is also moving towards creating a more uniform regulatory framework across EU countries. With rising concerns over misleading practices and the impact of influencers on vulnerable audiences, EU regulatory bodies hope to protect consumers even more.
Despite the softer approach of UK regulators, our report shows that UK businesses still endeavour to follow regulations. Yet, they are less invested in social issues than their European counterparts.
UK brands care less about bullying, discrimination, the use of minors for promotions, and sustainability than their EU counterparts. So, why are ethics such a non-issue in the UK?
It’s difficult to say exactly. While choosing more casual campaigns may explain the indifference towards influencers sticking to cooperate ethics, there are likely other cultural and political issues at play.
Let's consider a few of the possibilities.
Four years on from the official exit, fractured relationships with the EU, longer queues, and immigration frequently pop up in the news.
Another result of Brexit is that the UK now has a more relaxed regulatory environment, which has led to divergence from stricter EU guidelines on corporate ethics and responsible business practices.
EU countries are subject to stricter regulations like the Sustainable Finance Disclosure Regulation and Corporate Sustainability Reporting Directive, which push companies to prioritise social and environmental issues.
During Liz Truss's tenure, the UK Government introduced the Retained EU Law (Revocation and Reform) Bill, aimed at ensuring that most EU laws retained post-Brexit will expire by the end of 2023. However, 69% of businesses are against lowering UK standards.
Reuters found that 62% of UK brands care about ESG. At the same time, a study by the Boston Consulting Group found that 76% of UK consumers are actively trying to make more sustainable and ethical purchasing decisions, and they expect brands to do the same.
Additionally, 57% of consumers say their perception of a brand is directly influenced by its sustainability practices, while 30% are compelled to take action—either by switching brands or advocating for or against them—based on how a brand addresses social and environmental issues.
However, despite this strong interest in ethical behaviour, only 8% of UK consumers are willing to pay a 12% premium for sustainable products. The British public's lack of investment in sustainability may explain why some UK brands are less proactive about social issues.
But it's no surprise consumers are unwilling to shoulder the costs of ethical consumerism. UK consumers saw the cost of living rise by 53% more than the European average, which has likely led to more conservative, practical spending habits.
High inflation has also put pressure on businesses across the UK. All of these may be impacting the UK population and businesses' approach to ethics.
Cultural differences also play a role in how businesses view their responsibility to society. European markets, especially Scandinavians and other Northern Europeans, have a long-standing tradition of integrating social and environmental considerations into business practices. UK businesses tend to have more traditional profit-driven mindsets.
Brands may be taking a risk by not prioritising ethics. Globally, there is a growing push towards ethical consumerism, including "Underconsumption Core", which promotes second-hand shopping and reduced purchasing.
When a brand is perceived as unethical or collaborates with "unethical" influencers, it's reputation may be harmed. A prime case study is Molly-Mae Hague's partnership with PrettyLittleThing (PLT). Hague faced backlash after making comments perceived as tone-deaf regarding poverty and hard work, which reflected poorly on PLT. This incident was particularly damaging as it came alongside criticism that PLT was paying its factory workers below minimum wage, sparking further negative attention. Perhaps due to these challenges and the competitive market of fast fashion, PLT's profits have been falling.
In such cases, ethical missteps can lead to long-term harm, as a tarnished brand image reduces customer loyalty, negatively impacts sales, and potentially limits the brand’s ability to attract and retain employees.
So brands need to set a high standard and follow regulations while maintaining ethical values.
Here are some ways brands can enhance the ethics of their IM strategy:
These help you run better campaigns and can increase your return on investment over time.
UK brands might lean towards complying with regulations, but building an ethical foundation in influencer marketing is just as important. While some companies may deprioritise ethics during economic challenges—especially as consumers continue to buy despite ethical concerns—a strong ethical approach has the potential to foster long-term growth and loyalty. By focusing on both compliance and values, brands can achieve a balance that resonates with evolving consumer expectations.
