UK Gambling Commission Research Details Patterns Among Illegal Site Users

The UK Gambling Commission released findings from two linked studies in late October 2026 that examined consumer behavior around unlicensed gambling operators, and the results drew attention to distinct usage patterns when compared with licensed platforms. One analysis reviewed Open Banking transaction records from 179 individuals and identified 3,426 payments directed to suspected illegal operators while the second component involved a Yonder survey of more than 4,000 recent gamblers that captured self-reported reasons for choosing particular sites.

Transaction Data and User Overlap

Researchers examined payment flows and discovered that 91 percent of individuals who made repeat transactions with suspected illegal operators maintained active accounts on licensed sites at the same time. The data further showed no substantial reduction in activity on regulated platforms after users began sending payments to unlicensed operators, which indicates that illegal gambling tended to supplement rather than displace play on licensed sites for this group. Observers note that the 3,426 recorded payments came from a relatively small sample, yet the consistency of dual-site activity across most participants provided a clear picture of overlapping engagement.

Problem Gambling Score Comparisons

Participants who used illegal sites recorded markedly higher scores on the Problem Gambling Severity Index, with 45 percent reaching the threshold of 8 or above compared with 6 percent among those who gambled exclusively on licensed platforms. The contrast emerged from the same Open Banking dataset and aligned with survey responses collected in the parallel Yonder study. Those figures appear in the combined release dated October 2026, and analysts have since referenced the gap when discussing risk profiles associated with different operator types.

Timing and Release Context

The studies were published on 20 and 28 October 2026 respectively, and coverage of the findings continued into November as industry observers and support organizations reviewed the numbers. The Commission presented the Open Banking analysis and the Yonder survey as Phase 3 of its Consumer Voice research programme, with both components designed to track emerging trends in consumer choice. Because the research relied on actual transaction data rather than estimates alone, it offered a granular view of payment behavior that earlier surveys had not captured at the same level of detail.

Implications for Licensed and Unlicensed Activity

Because the majority of repeat illegal-site users also remained active on licensed platforms, the findings suggest that total gambling volume for some individuals may increase when unlicensed options become accessible. The absence of any measurable drop in regulated play after illegal activity began further supports the view that the two channels operate in parallel for this cohort. Researchers have noted that the 45 percent problem-gambling rate among illegal-site users stands in contrast to the 6 percent rate observed in the licensed-only group, although the studies stop short of establishing causation between site choice and gambling severity.

Conclusion

The October 2026 releases from the UK Gambling Commission provide concrete transaction and survey evidence on how some consumers interact with unlicensed operators while maintaining simultaneous use of regulated sites. The documented 3,426 payments, the 91 percent overlap rate, and the elevated PGSI scores together form a dataset that regulators and researchers can reference when assessing the reach of illegal gambling activity. The linked Yonder survey adds context on user motivations, particularly the appeal of sites outside the GamStop framework, and the combined material remains available for further examination through the Commission’s published materials.
