A newly released report from the Gambling Commission estimates that around 1.4 million adults in Great Britain qualify as problem gamblers. The figure comes from a large-scale survey of more than 19,000 people and represents a major change in how the issue is being measured. In the past, regulators warned that results from such surveys should not be directly applied to the wider population. That caution has now been set aside.

By applying the 2.7% figure from the survey to Britain’s adult population, the Commission has confirmed that the scale of the problem is broader and more pressing than previously acknowledged. This shift has pushed the issue firmly into public debate.

Who Is Affected, And How?

The report highlights that problem gambling is not evenly spread across society. It is found to be more common in deprived areas, suggesting that financial strain and fewer resources heighten vulnerability. It also points to particular gambling formats that carry higher risks. Slot machines and in-play sports betting are especially associated with addictive behavior, as their fast pace and continuous play increase the potential for harm.

The findings show that those who already face challenges in life are often more exposed to the damaging effects of gambling. In short, the risks are concentrated among the most vulnerable.

The Numbers That Matter

The 2.7% prevalence rate was calculated using the “problem gambling severity index,” a well-established tool designed to measure the harmful consequences of gambling. In earlier years, the Commission was hesitant to apply such results to national population figures. Following new statistical analysis, the Commission now considers the evidence strong enough to do so.

To place the estimate in perspective, 1.4 million people is a number greater than the population of Birmingham, one of the largest cities in the country. This shift in approach reflects how seriously the issue is now regarded at the regulatory level.

The Politics of Tax and Duty

The release of the new figures coincided with political discussions on how the gambling sector should be taxed. Chancellor Rachel Reeves recently signaled an interest in raising taxes on gambling businesses. Former prime minister Gordon Brown has gone further, suggesting that gambling duty could be increased by up to £3 billion to support social spending, including efforts to ease the two-child benefit cap.

Industry observers expect some form of tax rise, though likely at a smaller scale than Brown’s proposal. This debate captures the central tension: gambling provides the government with billions in tax revenue and creates employment, but the social costs, if left unchecked, risk overshadowing these benefits.

How the Industry Reacts

The Gambling Commission has called on operators to carefully review their customer data and to identify patterns of risky behavior. Andrew Rhodes, the Commission’s chief executive, urged companies to use the findings to reassess the risks within their customer base.

At the same time, the Betting and Gaming Council has expressed reluctance to embrace the higher prevalence figures, preferring to rely on older and lower estimates. This contrast signals a likely conflict between regulators pressing for reform and an industry intent on protecting its financial interests.

What This Really Means

This report represents more than a new statistic. It signals a turning point in how gambling harm is understood and addressed in Britain. The government now has a clearer picture of the scale of the problem, regulators have adopted a new approach to interpreting data, and the industry is under mounting scrutiny.

The coming months will show whether policy makers push for higher taxes to fund social protection measures, and whether gambling platforms strengthen safeguards for vulnerable customers. Public health agencies may increase demands for oversight, while communities most affected are likely to call for stronger protections.

The reality is difficult to ignore. Britain faces a moment of reckoning in its relationship with gambling. The evidence is clear, the costs of inaction are rising, and the demand for change is growing louder.
