562,000 and Counting – GamStop's Registration Trajectory

Numbers in this industry often get thrown around without context. Operators cite player counts in the millions, regulators quote enforcement figures in the hundreds of thousands, and everyone frames their preferred statistic to suit a narrative. But the GamStop registration figure – more than 562,000 individuals by the end of 2025 – is harder to spin. Each registration represents a person who decided, at a specific moment, that they needed to be locked out of every UKGC-licensed gambling site in Britain. That’s not a metric you massage for a press release.

I’ve tracked GamStop’s trajectory since its launch, and the consistent upward curve tells a story that neither the industry nor regulators can afford to ignore. The system is doing what it was designed to do – providing a friction-heavy barrier between vulnerable players and licensed operators. But the scale of uptake also raises questions about whether the conditions driving people to self-exclude are getting worse, and what happens to the proportion who don’t stay excluded.

H2 2025 Numbers – 319 New Sign-Ups Per Day

When I first saw the half-year figures for July through December 2025, the daily average stopped me: 319 new registrations per day. That’s 58,675 people in six months choosing to cut themselves off from the entire UKGC-licensed ecosystem. To put that in perspective, it’s roughly the population of a small English town – every six months.

The cumulative total crossing 562,000 represents years of compounding growth. GamStop doesn’t publish a churn figure – how many people’s exclusions have expired and not been renewed – so the headline number includes everyone who has ever registered, minus those who have been removed after their exclusion period ended. What we do know is that the inflow consistently exceeds any outflow, meaning the active excluded population keeps expanding.

These numbers carry weight in policy discussions. When the government debated the Remote Gaming Duty increase, the size of the GamStop register was cited as evidence that the licensed market generates significant harm. When operators argue that tax increases push players offshore, the counter-argument is that hundreds of thousands of people have already signalled distress within the regulated system. Both readings of the data have merit, and both are incomplete – but the underlying figure is hard to argue with.

Seasonality also matters. Registration spikes tend to follow major sporting events and the January “reset” period when people reassess habits after the holiday season. The H2 2025 data, covering July through December, captures the autumn football season and the approach to Christmas – periods when both advertising spend and gambling activity peak. Whether daily sign-ups sustain at 319 through quieter months will shape how the full-year 2026 figures look, but the trend line has pointed in only one direction since GamStop launched.

The 40% Surge in 16-24 Registrations

Here’s the number that should concern everyone in this industry, regardless of which side of the regulatory debate they sit on. Registrations among 16-to-24-year-olds jumped 40% year on year in H2 2025. This age group now accounts for 29% of all new sign-ups – nearly a third of the intake.

Younger users behave differently within the system. While 47% of all GamStop registrants choose the five-year exclusion period, 38% of 16-to-24-year-olds opt for just six months. That pattern suggests a different relationship with self-exclusion: less a permanent exit, more a temporary circuit-breaker. Whether that’s a positive sign – young people intervening early before habits entrench – or a warning sign – young people cycling in and out of self-exclusion without addressing underlying behaviour – depends on your interpretation.

What I find most telling is the gap between this demographic data and the industry’s marketing focus. Mobile-first design, social media promotion, gamification elements in slot mechanics – all of these skew toward younger audiences. The same cohort being targeted most aggressively is also the one self-excluding at the fastest rate. That’s not a coincidence, and it’s the kind of data point that shapes regulatory thinking for years to come. Student gambling surveys reinforce the picture: 65% of UK students gambled in the past year, and 18% met the threshold for problem gambling classification. The pipeline from casual play to self-exclusion is shorter than anyone in the industry would like to admit.

One in Ten Self-Excluded Players Still Use Offshore Sites

If the registration numbers tell you how many people want to stop, this figure tells you how many can’t – or at least don’t. Approximately one in ten GamStop-registered individuals admit to regularly using offshore casinos that sit outside the system’s reach. With 562,000 registrations, that implies tens of thousands of people who have formally excluded themselves from licensed gambling but continue to play at non-GamStop sites.

I’ve spoken with some of these players over the years, and the pattern is consistent. They register with GamStop during a moment of clarity or crisis, successfully block themselves from every licensed UK operator, and then – days, weeks, or months later – find their way to an offshore site through a search engine or a recommendation on social media. GamStop was never designed to block access to unlicensed operators, and it can’t. It covers UKGC licensees only. The self-excluded player who types “casinos not on GamStop” into a search bar is, in a real sense, the person the system was built to protect – and the person it structurally cannot reach.

This leakage rate is one of the strongest arguments for tools like BetBlocker, which operates at the device level and blocks access to gambling sites regardless of their licensing status. It’s also why the UKGC’s enforcement strategy – taking down URLs, issuing cease-and-desist orders, pressuring search engines to delist offshore operators – has a direct harm-reduction dimension beyond the obvious regulatory one. Every offshore site that becomes harder to find is one fewer escape route for a self-excluded player looking for a way back in. The full picture of UK online casinos not on GamStop makes more sense once you understand the scale of the population they serve – and the vulnerability embedded within it.
