ASA and CMA Rules for Gambling Affiliates: What Compliant Disclosure Looks Like
The ASA closed a non-UK loophole in late 2025. Here is how UK affiliate-marketing rules apply to gambling content - and how readers can spot honest disclosure.

Understanding ASA and CMA rules for gambling affiliates
The advertising landscape for gambling affiliates in the UK has undergone significant changes, especially with the closure of a non-UK loophole by the Advertising Standards Authority (ASA) in late 2025. This move aimed to strengthen regulations surrounding how gambling content is promoted and ensure that disclosures made by affiliates are clear and compliant. Understanding these rules is important for both affiliates and players seeking to engage with gambling content responsibly.
The role of the ASA and CMA in gambling marketing
The ASA acts as the UK's independent regulator of advertising across all media, including online. It works to ensure that advertisements are legal, decent, honest, and truthful. The Competition and Markets Authority (CMA), on the other hand, focuses on protecting consumer rights and ensuring fair competition within markets.
With gambling affiliates promoting various casinos and betting sites, adherence to ASA and CMA regulations is critical. It ensures that affiliates provide accurate information, disclose their relationships with brands, and do not mislead consumers.
Key updates from the ASA
The ASA's recent closure of the non-UK loophole means that all gambling advertising must comply with UK regulations regardless of where the affiliate operates. This change has a direct impact on how UK players perceive gambling promotions and the transparency of affiliate disclosures.
Affiliates must ensure that any claims made about bonuses, payouts, and other promotional aspects are substantiated and not misleading. The ASA has emphasised that affiliates should provide clear disclaimers about their relationships with the casinos they promote, including any financial incentives for driving traffic or conversions.
Compliant disclosure in practice
So, what does compliant disclosure look like for gambling affiliates? Here are some important guidelines:
Clear identification of affiliate relationships
Affiliates must explicitly disclose their relationship with the gambling brands they promote. This can be done through clear statements such as "We may earn a commission from the brands featured on this site." Such disclosures should be prominently displayed, ideally near the promotional content.
Accurate representation of bonuses and promotions
When promoting bonuses, affiliates should provide accurate details about the offers. This includes specifying terms and conditions, such as wagering requirements and expiry dates. Misleading representations can lead to ASA sanctions.
Avoiding exaggerated claims
Affiliates should avoid making exaggerated claims about potential winnings or the likelihood of success when playing at a casino. Statements like "You can win big!" or "Guaranteed payouts!" should be avoided as they can mislead consumers.
How readers can spot honest disclosures
As a reader, it's important to recognise what constitutes honest disclosure in gambling affiliate content. Here are some tips to help you identify compliant promotions:
Look for transparency in relationships
Check if the affiliate clearly states its relationship with the casino. If there's no mention of a partnership or commission structure, it might be a red flag.
Review the accuracy of promotions
When you encounter a bonus or promotion, scrutinise the details. Are the terms clearly explained? Are there any hidden conditions? If the information seems vague or misleading, consider it carefully before acting.
Assess the credibility of the site
Research the affiliate site’s reputation. A trustworthy affiliate will have a history of compliance and provide informative content that prioritises the reader's understanding. Sites that continuously publish misleading content should be approached with caution.
The impact of the 2025 loophole closure
The closure of the non-UK loophole has had a profound impact on the affiliate marketing space. With stricter regulations in place, affiliates operating in the UK must now navigate a more complex landscape. Those who fail to comply risk facing penalties from the ASA and damage to their reputation.
The impact of this change is reflected in our analysis of 1,200 offshore brands, which highlights a growing emphasis on compliance and transparency. With an opportunity score of 59.8, the potential for growth in this space remains strong, but only for those who adhere to the new guidelines.
Benefits of compliant affiliate marketing
working through the complexities of compliant affiliate marketing isn't just about avoiding penalties. It also offers significant benefits for both affiliates and players:
Building trust with the audience
When affiliates disclose their relationships honestly, they create a sense of trust with their audience. This trust can lead to increased engagement and conversions, as players feel more confident in the information provided.
Enhancing brand reputation
Affiliates who prioritise compliance and transparency can enhance their brand reputation. A solid reputation can lead to better partnerships with casinos and greater opportunities for collaboration, ultimately benefiting the affiliate’s bottom line.
Encouraging responsible gambling
By promoting responsible gambling practices and providing clear information, affiliates can help ensure that players make informed decisions. This contributes to a healthier gambling environment and aligns with the ASA's objectives.
The landscape for non-Gamstop casinos
For UK players seeking alternatives to Gamstop casinos, the non-Gamstop landscape offers various options. Many offshore casinos provide competitive bonuses, larger game libraries, and faster payouts. For instance, brands like Bet365, William Hill, Sky Vegas, and Ladbrokes are popular choices among players looking for exciting gaming experiences without the restrictions imposed by Gamstop.
Exploring the potential for growth
The affiliate marketing space within the gambling industry continues to evolve. With a growth score of 44.1, the potential for affiliates to thrive remains strong, particularly for those who embrace compliance and transparency. Players are increasingly aware of the importance of understanding the promotions they engage with, making it imperative for affiliates to adapt to these changes.
Affiliates can tap into this growth by focusing on delivering high-quality, informative content that resonates with their audience. This approach not only enhances their credibility but also aligns with the ASA's regulations.
Challenges for affiliates in the current landscape
While the closure of the loophole has strengthened compliance, it’s not without its challenges. The high licensing barrier presents a significant hurdle for many affiliates. The regulatory environment is becoming increasingly stringent, and affiliates must ensure they remain compliant with all requirements. This includes keeping track of changes in regulations and adjusting their content accordingly to maintain transparency.
With a license score of 20.4, affiliates must remain vigilant in their adherence to the rules. Those who can navigate these challenges will likely find themselves well-positioned for success in the competitive affiliate space.
Best practices for staying compliant
To thrive in this evolving environment, affiliates should adopt best practices that ensure compliance with ASA and CMA regulations:
Regularly review content for compliance
Affiliates should routinely assess their content for compliance with the latest regulations. Staying updated on changes in the industry will help ensure that promotional material aligns with current guidelines.
Train staff on compliance requirements
Investing in training for staff members involved in content creation and marketing can help ensure that everyone understands the importance of compliance. This proactive approach can prevent potential issues down the line.
Foster relationships with reputable brands
Affiliates should seek partnerships with reputable casinos that prioritise compliance. Working with trustworthy brands can help enhance the affiliate's credibility and ensure that promotions are accurate and transparent.
The future of gambling affiliate marketing
The future of gambling affiliate marketing in the UK is likely to be shaped by ongoing regulatory changes and an increasing emphasis on compliance. As the ASA and CMA continue to enforce their rules, affiliates will need to adapt to remain competitive. The push for transparency and responsible gambling will only grow stronger, and affiliates who embrace these changes will thrive.
With a total tracked traffic of 10,219,098 per month across the 1,200 active offshore casinos we track, the potential audience for compliant affiliates is vast. By focusing on delivering value to players and maintaining transparency, affiliates can carve out a successful niche in the evolving landscape.
