The Gambling Commission’s latest analysis of player behaviour has quantified something rarely measured: the toll gambling takes on people who don’t gamble themselves. Nearly 9% of British adults, roughly 1.6 million people, experienced at least one adverse consequence from someone else’s gambling in 2024, according to data released this week from the Gambling Survey for Great Britain.

A Hidden Population in Plain Sight

The finding emerges from analysis of responses from nearly 20,000 adults aged 18 and over. What makes this research particularly noteworthy is its focus on what the Commission terms “affected others” a population often invisible in conventional gambling harm discussions, which typically centre on the gambler themselves.

The demographic profile of affected others reveals some striking patterns. The group skews younger and notably female (55%), with nearly half aged between 25 and 44. More intriguingly, 63% of affected others had themselves gambled in the past year, which complicates any straightforward narrative about harm spreading from active gamblers to passive bystanders. In households where multiple people gamble, the Commission suggests, harmful outcomes compound across financial, relational, and health domains.

The Overlap With Problem Gambling

This overlap matters significantly. Among affected others who also gambled, 21.5% scored in the problem gambling range on the Problem Gambling Severity Index, compared to just 4.5% across all gamblers. That’s a near five-fold increase. It suggests that people already vulnerable to problem gambling are disproportionately likely to be harmed by others’ gambling as well.

The types of harm reported paint a sobering picture. Health-related consequences dominated, with 73.7% of affected others experiencing stress or anxiety, shame or embarrassment, or increased conflict and arguments. Relationship breakdown was cited by 65.3%, and financial harm by 42.5%. More than one in four reported severe consequences: relationship breakdown, significant financial loss, violence, and criminal activity.

Support Remains Elusive

Despite these figures, uptake of support services remains stubbornly low. Just 14.5% of affected others sought help in the past year, though those who gambled themselves were more likely to access mental health, welfare, and gambling-specific services (18.3% versus 7.7% among non-gamblers). The disparity points to a troubling gap: those without their own gambling history may not recognise available resources as relevant to their situation, or lack awareness entirely.

The government’s recent £25.4 million investment in gambling-harm prevention services signals recognition of these gaps. Whether that funding translates into better outreach and support specifically tailored for affected others remains to be seen. The Gambling Commission has signalled plans for further qualitative research to better understand the dynamics of harm in relationships and social networks where gambling is present.

For industry participants and policymakers alike, the data underscores a fundamental reality: gambling’s impact extends well beyond the individual at the betting terminal or online account.

What the team thinks

Sheena McAllister says:

Philippa’s piece rightly spotlights a critical blind spot in our regulatory framework, and the 9% figure should prompt serious reflection from operators and policymakers alike, but what strikes me from a compliance perspective is how this data underscores the inadequacy of current safer gambling measures that remain overwhelmingly focused on individual player behaviour rather than household and social impact. The Gambling Commission’s expansion of harm measurement is commendable, yet operators must recognize that meeting minimum licensing standards around problem gambling tools won’t be sufficient if we’re seeing this scale of secondary victimization, and the industry would be wise to view this not as regulatory burden but as evidence that more sophisticated, family-aware safer gambling interventions could become a genuine competitive differentiator. This conversation needs to shift from “are we compliant?” to “are our safeguarding tools actually preventing the harms we now know exist beyond the individual bettor?”
