New research from H2 Gambling Capital (H2GC), shared by the Betting and Gaming Council (BGC), has revealed a disturbing surge in illegal gambling activity within the United Kingdom. Illegal stakes have nearly tripled since 2019, rising from £5 billion to a staggering £16.6 billion this year.
The data suggests that profit margins for offshore, unlicensed operators have doubled in just the last 24 months.
The Consequences of Regulatory Friction
The BGC argues that the rapid expansion of the black market is a direct result of over-regulation within the licensed sector. As legal operators face higher taxes and the proposed implementation of “affordability checks,” players are increasingly migrating to offshore sites that offer no safer gambling protections or age verification.
Grainne Hurst, CEO of the BGC, warned:
“What we are seeing is a harmful black market scaling up at pace. Illegal operators are becoming more sophisticated, more visible and more aggressive in how they reach UK customers. The choice for policymakers is clear. If the regulated sector becomes harder to use or less competitive, customers will not stop betting, they will simply go elsewhere.”
The Advertising Rift
Further complicating the issue, WARC analysis indicates that unlicensed operators now account for nearly 50% of all UK gambling advertising spend. This visibility makes it nearly impossible for consumers to distinguish between legitimate and “harmful” platforms.
Former Gambling Minister Stuart Andrew MP has joined the chorus of critics calling for a rethink on financial risk assessments, noting that the original promise of “frictionless” checks has not been met by current pilot schemes.
As per the H2GC, If the trend continues, the BGC fears the legal market’s share of activity, which sat at 97% in 2019, could continue its dangerous decline toward 90% and below.
