UK Illegal Gambling Traffic Surges Despite Regulatory Crackdown

Unlicensed gambling websites are attracting significantly more British visitors than five years ago despite an aggressive enforcement surge by the UK Gambling Commission (UKGC), according to a new report from the International Federation of Horseracing Authorities (IFHA). Researchers found that illegal betting websites received 19 visits from UK users for every 100 visits to licensed platforms, up from just one visit per 100 in late 2021.

The IFHA concluded that the Gambling Commission’s expanded enforcement measures have yet to produce a sustained drop in black-market betting traffic, as illicit operators build longer engagement times and expand their audience.

Website Traffic Up Fourteenfold

The IFHA’s analysis revealed dramatic traffic growth across unlicensed betting sites between 2022 and 2025. Visits to illegal platforms spiked fourteenfold during the three-year window, while traffic to licensed gambling websites fell by 34%.

Engagement metrics show British users are staying longer once on the sites. Since late 2024, UK users have spent roughly one-third longer per visit on illegal gambling platforms and viewed one-third more pages during each session. The IFHA described the trend as clear evidence that black-market operations are becoming “more competitive, not just more visible,” even while licensed brands retain an overall lead across total engagement.

Official Survey Shows a Broader Gap

The IFHA’s web-traffic findings contrast with the Gambling Commission’s own general-population data. According to the regulator’s latest Gambling Survey for Great Britain, 94.4% of respondents showed no history of accessing illegal gambling sites, indicating low overall participation across the wider public.

The Commission reported that 0.6% of respondents had visited an illegal platform in the past four weeks, with another 0.4% doing so over the previous 12 months. Among active online gamblers, those numbers rise to 2.5% for recent four-week use and an additional 1.5% over the past year.

The divergence highlights two distinct measuring sticks: the IFHA tracked total site traffic and user session depth, whereas the UKGC measured self-reported individual participation across the general public.

A £26 Million War Chest

The traffic report arrives as the UKGC scales up its enforcement machinery following a £26 million funding injection allocated in the November 2025 Budget. That backing was followed by the launch of a multi-agency Illegal Gambling Taskforce in May to coordinate cross-border disruption.

Regulator figures show rapid enforcement scaling:

• Cease-and-Desist Letters: Issued 1,005 warnings between April and September of the current financial year, already eclipsing the 741 letters sent throughout the entire previous year.
• Search Engine Referrals: Flagged over 7.8 million URLs to search providers in six months, up from 397,527 referrals in the previous year.
• Takedowns Executed: Secured the removal of 3,038,969 illegal URLs from search results, compared to 266,667 total removals in the prior 12-month period.

Measuring a Moving Market

The conflicting datasets underscore how difficult it remains to map Great Britain’s underground gambling market. While self-reporting surveys indicate that black-market gambling remains a niche behavior among the broader public, web traffic metrics show that active users are consuming illicit platforms at an unprecedented scale.

With £26 million in dedicated enforcement funding deploying through 2028, the Gambling Commission faces the task of converting record URL takedowns and cease-and-desist orders into a measurable decline in black-market site traffic.
