The UK Gambling Commission released fresh data tracking UK player visits to illegal gambling sites, covering a 21-month stretch right up to February 2026; figures show no sustained growth in that traffic, even as VPN usage climbed sharply following the Online Safety Act's rollout.
Traffic levels bobbed up and down without settling into any clear upward climb, a pattern that experts tracking the illegal market have pored over closely, especially since this marks the first major update since November 2025.
Researchers at the Commission rely on sophisticated tools to gauge visits from UK IP addresses to unlicensed offshore sites, those operators dodging UK licensing requirements and player protections; over those 21 months, raw data captured fluctuations that never broke into consistent expansion, holding steady around baseline levels despite external pressures like heightened enforcement.
But here's the thing: VPNs muddied the waters, letting users mask their locations to slip past blocks on illegal domains, a tactic that ramped up after the Online Safety Act kicked in, mandating tech firms to clamp down on harmful content including unlicensed gambling.
Data indicates VPN adoption spiked in the UK post-Act, with providers reporting jumps in subscriptions; yet the Commission's adjusted metrics, factoring in that rise, still point to stable illegal site traffic, no explosion in player migration as some had feared.
Those who've studied similar markets note how such monitoring blends public web analytics, proprietary trackers, and cross-checks with firms like Similarweb, painting a fuller picture than raw hits alone could offer.
To counter VPN obfuscation, the Commission applied a 30% uplift to obscured visits, a conservative tweak drawn from external benchmarks by Ofcom and Similarweb; this adjustment accounts for the portion of UK traffic likely funneled through proxies, ensuring estimates don't lowball the real reach of illegal operators.
Figures reveal that even with this boost, monthly traffic hovered without a sustained surge, dipping in some periods and peaking briefly in others, but always snapping back; for instance, post-Act implementation saw a temporary blip tied to initial blocks, yet levels normalized quickly thereafter.
What's interesting is how this methodology evolved; external data from Ofcom's broadband surveys and Similarweb's global traffic models fed into the uplift calculation, grounding it in observable VPN penetration rates across the UK population.
Experts observing these refinements point out that such adjustments prevent over- or under-estimation, crucial when policymakers weigh crackdowns or licensing tweaks.

Commission staff unveiled this update at their Spring Evidence Conference in Birmingham, drawing together industry reps, HMRC officials, and international regulators like the Dutch authority; attendees dissected the 21-month dataset, hashing out ways to sharpen illegal market surveillance amid tech shifts like VPN proliferation.
Discussions zeroed in on collaborative tools, from shared IP blocklists to AI-driven anomaly detection, as participants swapped notes on cross-border operator tactics; the Dutch contingent, fresh from their own offshore battles, highlighted parallels in player traffic patterns, underscoring how UK findings ripple outward.
HMRC reps chimed in on fiscal angles, linking illegal gambling flows to unreported revenues, while industry voices pushed for transparent metrics to guide compliant operators; the event, held amid April 2026's regulatory buzz, signaled a pivot toward data-led strategies over guesswork.
One session broke down the VPN uplift in detail, with presenters walking through Ofcom stats showing 15-20% household VPN use by late 2025, climbing to 25% by February 2026; Similarweb contributed heatmaps of masked UK traffic hitting Asian and Curacao-licensed sites, validating the 30% buffer.
The Act, enforced from late 2025, compelled platforms to filter out illegal gambling links, prompting a predictable VPN scramble among users seeking unrestricted access; yet Commission data counters narratives of mass exodus to shadows, showing instead that licensed sites retained their pull, with illegal traffic failing to capitalize on the disruption.
Turns out, enforcement teeth from payment blocks and advertiser bans complemented the Act, squeezing illegal operators' visibility; observers tracking ad spend note a 40% drop in UK-targeted promos from unlicensed firms over the period, correlating with flat traffic.
People in the sector often point to self-exclusion tools and affordability checks on white-listed sites as anchors, keeping players from drifting offshore even when VPNs offer a workaround.
Diving into the timeline, traffic started steady in mid-2024, nudged up slightly during 2025's pre-Act hype, then fluctuated post-enforcement without breaking higher; February 2026 closed the window on a down month, adjusted figures dipping 5% from the prior peak, per Commission charts.
Such patterns emerge in case studies from prior years, where hype around regs sparked short spikes, only for reality to level things off; this dataset, spanning economic ups and downs including post-holiday lulls, reinforces that resilience.
And while VPN metrics from providers like ExpressVPN logged UK surges—doubling active users in Q1 2026—the uplift-capped traffic tells a tale of containment, not conquest by illegals.
Conference panels didn't stop at data dumps; they forged ahead on next-gen monitoring, like machine learning to unmask VPN clusters or partnerships with browser makers for real-time flagging; international ties, especially with Dutch peers who've throttled their own illegal inflows by 25% via similar uplifts, offer blueprints for UK scaling.
Industry feedback honed the 30% figure, suggesting quarterly recalibrations as VPN tech evolves; HMRC floated tying traffic intel to audit trails, closing loops on offshore winnings evasion.
It's noteworthy that this gathering, timed for spring 2026, positions the Commission ahead of looming reviews, ensuring metrics stay robust against operator pivots like crypto wallets or mirror domains.
As April 2026 unfolds, with fresh enforcement waves on the horizon, the data underscores effective guardrails; no sustained illegal traffic growth means protections are sticking, even as tech lets a few slip through—yet the tide holds firm.
Those analyzing long-term trends see this as validation for layered approaches: tech blocks plus behavioral nudges, keeping the bulk of UK players within licensed bounds.
The Commission's 21-month snapshot up to February 2026 delivers clear evidence—no runaway growth to illegal sites, VPN bumps notwithstanding; with the 30% adjustment anchoring estimates and the Birmingham conference fueling refinements, regulators stand equipped for whatever comes next, from AI evasions to global syncs.
Data like this doesn't just inform; it guides, ensuring the UK's gambling framework evolves with precision rather than panic, as evidenced by these steady lines amid the noise.
