Inside the UKGC's Campaign Against Illegal Offshore Operators

When Andrew Rhodes, CEO of the UK Gambling Commission, told an audience at the IAGR Conference in Toronto that his team was tracking over 1,000 illegal operators, I don’t think most people in the room grasped the scale. A thousand operators. Not a thousand websites – a thousand distinct operations, many running multiple domains, mirror sites, and affiliate networks. The illegal gambling market in Britain isn’t a fringe nuisance. It’s an industrial-scale operation, and the UKGC is running what amounts to a digital enforcement campaign against it.

I’ve followed this campaign since its early stages, and what’s changed isn’t the UKGC’s awareness of the problem – they’ve known about offshore operators for years. What’s changed is the tooling, the funding, and the political will to treat illegal gambling as a national enforcement priority rather than an unavoidable side effect of the internet.

327,964 URLs Flagged – The Numbers Behind Enforcement

Between April and December 2025, the UKGC sent 327,964 URLs to search engines for delisting. Let that number settle for a moment. Nearly a third of a million web addresses flagged in nine months, each one representing a page that was funnelling UK consumers toward unlicensed gambling.

Of those, 203,571 were actually removed – a takedown rate of roughly 62%. The gap between flagged and removed reflects the reality of working with search engines, which have their own policies and timelines for processing removal requests. It also reflects the speed at which illegal operators generate new URLs. Take down a page today, and a mirror appears tomorrow under a slightly different domain. The enforcement is real, but it’s a treadmill.

Alongside the URL campaign, the UKGC issued 592 cease-and-desist notices to operators and advertisers, sent 839 sites for formal delisting, and achieved the blocking or geo-blocking of 627 sites. The Illegal Gambling Taskforce, backed by 26 million pounds in additional funding over three years from the 2025 Autumn Budget, coordinates across government departments, law enforcement, payment processors, and international partners. This isn’t a skeleton crew filing complaints into a void. It’s a funded, multi-agency operation with measurable outputs.

Ismail Vali, president of Gaming Compliance International and founder of Yield Sec, has characterised the situation bluntly: illegal online gambling in Great Britain is approaching 10% market share, built through the exploitation of children and self-excluded players on the GamStop scheme. Whether that precise figure is accurate is debatable – I’ll address the reliability of offshore estimates elsewhere – but the direction of the data is not in dispute.

International Enforcement Cooperation

The UKGC isn’t operating in isolation. In late 2025, seven European gambling regulators – the UKGC, Italy’s ADM, Germany’s GGL, the Netherlands’ KSA, France’s ANJ, Spain’s DGOJ, and Portugal’s SRIJ – signed a Memorandum of Understanding to coordinate enforcement against offshore operators. I’ve covered this coalition and its implications in detail in a separate analysis of the European regulators’ MoU, but the relevance here is structural: an operator that gets flagged by the UKGC can now be simultaneously targeted by six other national regulators, each with their own enforcement powers, payment processor relationships, and ISP contacts.

This multilateral approach changes the economics for offshore operators. Previously, getting blocked in one country meant losing one market while continuing to operate freely in others. Coordinated enforcement means a single investigation can trigger parallel actions across multiple jurisdictions, making the cost of serving European markets from an offshore base significantly higher. It doesn’t eliminate offshore gambling – the internet makes that practically impossible – but it raises the barrier to entry and the cost of ongoing operation.

How Large Is the UK’s Illegal Gambling Market?

This is where the conversation gets contentious, because every stakeholder has an incentive to frame the number differently.

The Campaign for Fairer Gambling, using data from Yield Sec, estimates that illegal operators extracted 379 million pounds from UK consumers in just the first half of 2025, controlling approximately 9% of the online market. The Betting and Gaming Council puts the broader figure higher: roughly 1.5 million Britons staking up to 4.3 billion pounds annually on the unregulated market. These numbers come from organisations with different agendas – the Campaign for Fairer Gambling advocates for tighter regulation, while the BGC represents licensed operators who benefit from framing the black market as a competitive threat that justifies lower taxes.

What’s not in dispute is the trend. Every credible analysis shows the illegal market growing, not shrinking. H2 Gambling Capital projects that onshore iGaming channelisation – the proportion of gambling activity that occurs within the licensed market – will fall from 92-93% to approximately 80% following the April 2026 tax increase. If that projection materialises, the illegal market doesn’t just grow incrementally. It roughly doubles in absolute terms.

The illegal stream ecosystem amplifies the problem. In 2024 and the first half of 2025, 89% of illegal sports streams consumed by British viewers carried advertising for unlicensed gambling operators. Across 4.7 billion illegal stream views, that’s an advertising reach that no legitimate marketing channel can match. The pipeline from pirated football stream to offshore casino deposit is direct and well-documented, and it operates entirely outside the reach of UK advertising standards.

The UKGC’s enforcement campaign is significant in scale, growing in funding, and increasingly coordinated with international partners. But it’s fighting against economic forces – tax differentials, regulatory asymmetry, and the structural openness of the internet – that create persistent incentives for offshore operators to target UK consumers. The numbers tell a story of genuine effort meeting a problem that refuses to shrink.
