UK Remote Gaming Duty Increase Fuels Expansion of Offshore Betting Markets

Independent analysis commissioned by the Betting and Gaming Council reveals how the Chancellor's decision to raise Remote Gaming Duty to 40 percent starting April 2026 has coincided with accelerated movement of customers toward illegal offshore platforms, and observers note the timing aligns with broader economic pressures on regulated operators.

Data compiled by H2 Gambling Capital tracks offshore online gambling turnover climbing from £5 billion in 2019 to £16.6 billion at present, with projections indicating a further rise to £36 billion by 2031; the same figures show the illegal segment's share of total online betting expanding from an estimated 10 percent in 2025 to 22 percent by 2031, a development that researchers link directly to the tax adjustment.

Details of the Tax Adjustment and Initial Market Response

The policy change lifted the duty rate from its previous level and applied it across remote gaming activities, a move that took effect in the spring of 2026, and analysts at H2 Gambling Capital documented subsequent patterns in customer behavior that emerged in the months immediately following implementation.

Those who examined transaction flows reported that certain segments of the player base began exploring offshore alternatives more actively once the higher duty began influencing pricing structures within the licensed market, while data from June 2026 captured the early trajectory of this shift in real time.

Turnover Trends Across the Offshore Sector

Offshore turnover has followed a consistent upward path since 2019, accelerating after the duty hike entered force, and the H2 Gambling Capital model attributes part of the recent growth to displacement effects rather than organic demand alone. The trajectory shows annual increments that compound toward the £36 billion forecast for 2031, a level that would represent more than double the current volume according to the projections released in the June report.

Market share calculations within the same analysis indicate the illegal component rising from 10 percent in 2025 to 22 percent by 2031, a doubling that researchers tie to the altered cost environment created by the 40 percent duty rate, and the report presents these percentages alongside turnover estimates to illustrate the scale of the projected reallocation.

Regulatory Context and Enforcement Considerations

The Betting and Gaming Council presented the H2 Gambling Capital findings as evidence that tax policy influences the competitive balance between licensed and unlicensed operators, and the organization highlighted the need for enforcement resources to address the expanding offshore presence. Figures released alongside the analysis underscore how the illegal market's growth rate outpaces that of the regulated sector under the new duty structure.

Stakeholders reviewing the June 2026 report have noted that the projections extend through 2031, providing a multi-year view of how the April 2026 duty change could continue shaping market dynamics, while the data remains anchored in observed turnover patterns from 2019 onward.

Conclusion

The H2 Gambling Capital analysis commissioned by the Betting and Gaming Council supplies a quantitative snapshot of how the Remote Gaming Duty increase to 40 percent correlates with rising offshore activity, and the published turnover and market-share figures offer a factual basis for tracking these developments through the remainder of the decade.
