In the backdrop of the UK’s recent budget, where online gambling operators will be required to pay a new betting duty of 40% from April next year, renewed scrutiny has fallen on the scale of gambling advertising and its impact on consumers. Particular attention has been given to online slots, which have become one of the most heavily promoted forms of gambling across digital platforms.
In response to growing concerns around gambling harm and youth exposure, the UK has introduced more stringent restrictions on how gambling products can be advertised. Regulators have highlighted the role of social media in amplifying gambling promotions, with online slots frequently featured in digital marketing campaigns aimed at wide and often impressionable audiences.
These measures are expected to bring a sense of relief to consumers, especially those affected by gambling-related disorders such as addiction. They also contribute to creating a safer media environment for under-18s and others who may be particularly vulnerable to the influence of persistent advertising.
Why are online slots being targeted?
The crackdown on online slots appears to stem from a growing concern about gambling addiction and youth access to gambling. More calls have appeared in recent weeks for the government to ban gambling ads outright.
In London, Mayor Sadiq Khan is under growing pressure to ban gambling adverts on the Tube, with five London councils, Barnet, Enfield, Brent, Hackney, and Lewisham, joining the Coalition to End Gambling Ads (CEGA) in its bid to prevent the spread of harmful gambling promotions across the UK.
Five other councils from across the UK, including Blackpool, Bristol, Devon, East Suffolk, and Southampton, have also joined the CEGA to advocate for reform of gambling advertisements.
In November, a report from The Guardian revealed that UK gambling firms had spent over £2 billion on advertisements. This figure came from the media insights group WRAC and led to calls from politicians to increase taxes on online casinos in the Chancellor’s budget.
Meg Hillier, the chair of the Treasury Select Committee, said that calls made by lobbyists that a tax increase would result in job and revenue losses for the sector said that the government should not cave for “industry scaremongering,” while Labour MP Alex Ballinger said that gambling firms should “cut back” on adverts before complaining about tax increases.
Although calls for gambling reform encompass all types of gambling, online slots face a more urgent need for reform. Data provided by analyst firm Statista found that as of January 2025, online gambling was the most popular form of gambling in the UK at 37%.
How the new rules impact operators
A major impact for operators would be how they approach changing the way they market themselves in the UK. The news rules, set up by the UK’s advertising regulator, the Advertising Standards Authority (ASA), and updated to the Committee of Advertising Practice (CAP) code, state that offshore slot sites that promote their content in the UK would now have to adhere to rules that they were previously exempt from.
The rules focus on non-paid content marketing, which is mainly in the form of social media posts that overseas platforms use to promote content that would not be allowed if they were registered within the UK. This often includes influencer-led posts and organic promotions positioning platforms as the best new casino sites for UK players.
Industry reactions to tougher advertisement restrictions
Some industry professionals welcomed the restrictions, particularly those focused on gambling harm advocacy. University of Bristol marketing lecturer, Dr. Raffaello Rossi, welcomed the change, calling it “long overdue.” The lecturer has been at the forefront of fighting for more regulation surrounding gambling ads, especially their impact on children.
Some operators have since called out the ASA for pulling certain ads, although not related to online slots, Flutter Entertainment criticized the advertising watchdog after it pulled a Sky Bet tweet that it claimed was targeted to underage players. Flutter had said that the ruling lacked “common sense,” as regulated operators are reprimanded and black-market operators are not.
The claim from Flutter raises an important question about whether the ASA can properly regulate its new advertising rules. Although it’s upping its scrutineering process, many in the industry fear that regulated operators will be targeted more, leaving black-market operators free to continue pushing ads that target vulnerable players.
What it means for players
Although industry reactions haven’t been all positive towards the new rules, players are sure to benefit. With fewer advertisements cluttering up social media spaces, young adults and even teens are protected from seeing ads that could potentially inflict gambling addictions on them. On top of that, the restrictions don’t only safeguard under-18s but also adults suffering from gambling addictions.
Players will also be protected from deceptive imagery and exaggerated messaging that employs predatory techniques targeting vulnerable consumers. This includes types of ads that promise instant wins, easy rewards, and bonuses, which create a sense of urgency in consumers to play online slots so they can achieve big wins. People with prior addictions are more susceptible to these types of ads, as they can refuel addictive patterns and result in a relapse.
With this type of content now restricted, it gives rise to other forms of healthier advertising, such as responsible messaging and bringing awareness to help those suffering from addictions.
Conclusion
It’s unclear how the new advertising rules will impact online slots. Some operators have claimed that it would have a direct impact on revenue and jobs, but this has yet to be seen. However, it can be said that it will have a positive effect on consumers, with posts already being taken down in violation of the new rules.
All in all, positive and negative reactions to the new restrictions are two sides of the same coin; it’s a step in the right direction, but the fear of how black market operators can benefit is also a valid concern.
