5 Key Takeaways:

• The European Committee for Standardization has published EN 18144, the first common European technical framework dedicated to identifying potentially risky gambling behaviour through analysis of "markers of harm"
• The European Gaming and Betting Association, which submitted the proposal underpinning the initiative to CEN in 2022, has welcomed the standard's publication as an important step toward harmonising prevention tools and player protection across the European market
• The standard identifies nine main categories of behavioural indicators including betting volume, gambling speed and intensity, deposit behaviour, withdrawal cancellations, player-initiated contacts, session length, time band activity, simultaneous product use, net loss evolution and engagement with responsible gambling tools
• A central methodological principle is that no single indicator considered in isolation is sufficient to determine problematic behaviour, with the standard emphasising overall behavioural assessment to support proportionate interventions
• EN 18144 is voluntary and does not introduce new direct regulatory obligations, but EGBA has confirmed that most of its member operators already monitor all nine identified indicators and several have integrated them into their operational activities

Europe Has Built the First Shared Framework for Spotting Gambling Harm Before It Becomes a Crisis

The publication of European standard EN 18144 marks a significant step in how the European online gambling sector approaches consumer protection. For the first time, operators across the continent have access to a common technical framework for identifying potentially risky gambling behaviour, developed through the European Committee for Standardization with input from industry, national authorities, researchers and gambling harm experts.

The technical reference document, EN 18144:2025 "Online gambling – Markers of harm in support of identification and prevention of risky and problem gambling behaviour", was approved in 2025 and has now been made available through European national standardisation bodies. The European Gaming and Betting Association, which submitted the proposal underpinning the initiative to CEN back in 2022, has formally welcomed the publication as a milestone for harmonisation of player protection across the European online gambling market.

The standard's design reflects a deliberate shift from reactive to preventive approaches. Rather than intervening when gambling problems have become evident, EN 18144 aims to support early identification of risk signals through ongoing analysis of player activity on digital platforms. That preventive orientation is significant because it addresses one of the most persistent criticisms of historical responsible gambling efforts: that intervention has too often come at the point of obvious crisis rather than at the earlier stages where meaningful course correction is still possible.

A crucial methodological principle embedded in the standard is that the markers identified do not constitute a clinical diagnosis of gambling addiction and do not automatically determine the presence of problematic behaviour. Their function is to provide useful elements for an overall risk assessment based on the evolution of player habits and the interaction between different behavioural signals. That careful framing matters considerably because it positions operators correctly as data-driven prevention contributors rather than as substitutes for clinical assessment.

Nine main categories of behavioural indicators sit at the core of the standard. Betting volume tracks any significant changes in wagering compared with the consumer's usual behaviour. Gambling speed and intensity captures the pace of activity and the frequency of new bets. Deposit behaviour includes changes in frequency, amounts and incomplete deposit attempts. Withdrawal cancellations have been included as a particularly relevant signal because they may indicate a player's decision to continue using funds initially intended for withdrawal. Player-initiated contacts with the operator, overall session length, activity during certain time bands, simultaneous use of different gambling products and the evolution of net losses over time complete the indicator framework. A ninth category covers the user's relationship with responsible gambling tools, including changes to personal limits, use of temporary breaks and self-exclusion systems.

The standard's emphasis on combined rather than isolated analysis of these indicators is perhaps its most important methodological feature. A change in betting alone may have different meanings depending on context. The standard explicitly requires assessment alongside other elements, including session length, loss patterns, deposit frequency and changes in the use of protection tools. That insistence on holistic analysis is designed to support proportionate interventions rather than automatic responses that might misidentify normal variation as evidence of harm.

EN 18144 was developed through a collaborative process involving representatives of the online gambling industry, national authorities, researchers and experts in gambling harm prevention. The objective was to create a tool grounded in scientific research on player behaviour and applicable in practice by operators across multiple European jurisdictions. The approval of the standard represents an attempt to move beyond the fragmentation of different national approaches by establishing a shared technical reference point that operators and regulators alike can use as a benchmark.

EGBA Secretary General Maarten Haijer described the introduction of the standard as an important milestone for improving consumer protection, suggesting that broad adoption could help raise standards across the entire sector. The association has confirmed that most of its member operators already monitor all nine behavioural indicators identified by EN 18144, with several having integrated them into operational activities. The process of aligning with the standard across the different European jurisdictions in which EGBA members operate is expected to continue.

A defining feature of EN 18144 is that it remains voluntary and does not introduce new direct regulatory obligations. The document was designed to integrate with regulatory frameworks already in force in individual European countries while respecting the powers of different national authorities. In some markets, specific indicators may be applied differently if they conflict with local regulations, particularly around data processing or operational procedures. That flexibility allows the standard to serve as a common reference point without replacing national legislation.

Expert Analysis

The Methodological Discipline Is What Makes This Standard Meaningful

The insistence within EN 18144 that no single indicator should be treated as conclusive evidence of problematic behaviour reflects an unusually sophisticated understanding of how gambling harm actually manifests. Less rigorous approaches to behavioural monitoring have historically produced significant numbers of false positives, flagging normal variation in player activity as evidence of harm and triggering interventions that damage player relationships without delivering protective value. By requiring holistic assessment across multiple indicators, the standard creates the conditions for more accurate identification and more proportionate intervention. Operators that adopt this methodological discipline genuinely will see improvements in both player protection outcomes and operational efficiency. Those that treat the indicators as a checklist for triggering automatic interventions will miss the point entirely.

The Voluntary Status Is Both a Strength and a Limitation

Designing EN 18144 as a voluntary standard rather than a mandatory regulatory requirement was almost certainly necessary given the political complexity of imposing a single European approach across Member States with very different regulatory traditions. That voluntary status allows the standard to function as a shared reference point without overriding national authorities. The cost is that operators not minded to invest in serious behavioural monitoring face no direct compliance pressure to do so. Whether the standard becomes the genuine market norm or remains an aspiration largely confined to EGBA's more progressive members will depend on how national regulators across Europe choose to engage with it. The French ANJ's recent rollout of its own player-risk algorithm suggests at least some national regulators are moving in directions that align closely with the EN 18144 methodology, which could create indirect pressure on operators to align with both.

The Real Test Will Be How the Standard Performs Against the Illegal Market

EN 18144 addresses a genuine gap in how licensed European operators identify and respond to gambling harm, but it operates entirely within the regulated perimeter. The structural challenge that has been emerging across European gambling markets is that the most vulnerable players are increasingly migrating to unlicensed offshore alternatives where no equivalent protection framework applies. The Netherlands' recent channelisation data, France's findings about excessive play rates on illegal sites and similar patterns across multiple European markets all point to the same dynamic. A standard that improves protection within the licensed market while the unlicensed market continues to grow risks improving the experience of players who least need additional support while leaving the most at-risk players entirely outside its protective scope. EN 18144's value depends on being one component of a broader regulatory architecture that also addresses the unlicensed alternatives, and that broader work remains substantially less advanced than the standard itself.
