Tim Miller Set to Step Down from Gambling Commission Role in 2026

The UK Gambling Commission has confirmed that Tim Miller, its Executive Director of Policy and Research, will depart the organization in September 2026 after a decade of service. Miller joined the regulator in 2016 and has since shaped several core areas of its work including research development and policy implementation tied to the Gambling Act Review White Paper. His exit comes as the commission continues to advance regulatory frameworks across Great Britain and prepares for ongoing reforms scheduled through 2026 and beyond. Miller's responsibilities have centered on strengthening the evidence base that informs commission decisions. During his time in post he oversaw the creation and rollout of the Gambling Survey for Great Britain, a large-scale data collection project designed to replace earlier fragmented studies with a single consistent source of information on participation and harms. The survey now supplies annual figures that researchers and policymakers rely upon when assessing trends in online and land-based gambling. Observers note that Miller also played a direct part in translating White Paper proposals into operational rules. Those measures include updated age-verification standards that require operators to verify player identities before allowing deposits, financial risk checks that flag accounts showing signs of potential harm, and a range of safer-gambling tools such as deposit limits and reality checks. Implementation of these changes has occurred in stages, with further refinements expected before the end of 2026.

Key Contributions Across Ten Years

Colleagues and external stakeholders have highlighted Miller's focus on building internal research capacity. Before his arrival the commission maintained a relatively small policy team; under his leadership the unit expanded its analytical functions and established formal partnerships with academic institutions. The result has been a steady increase in published reports that examine everything from the effectiveness of self-exclusion schemes to the impact of stake limits on player behavior.

The Gambling Survey for Great Britain stands as one of the most visible outcomes of that expansion. Launched in its current form during Miller's tenure, the survey draws responses from tens of thousands of participants each year and provides breakdowns by age, gender, and product type. Commission statements indicate the data has already informed consultations on advertising restrictions and affordability assessments, both of which remain active policy areas heading into July 2026.

Transition to International Work

Following his departure Miller will assume an international position focused on supporting gambling regulation in jurisdictions outside the United Kingdom. The commission has not released further details about the new role, yet the announcement emphasizes that Miller's experience will continue to influence regulatory practice on a global scale. His successor has not yet been named, and the commission has indicated that recruitment will begin in the coming months.

Regulatory Landscape in 2026

The timing of Miller's exit coincides with several other commission milestones. July 2026 marks the midpoint of a multi-year program of White Paper reforms that includes additional consultations on credit card restrictions and marketing controls. Although Miller will leave before those later stages conclude, the frameworks he helped establish are expected to remain in place and guide the organization's approach.

Industry participants have described Miller as a consistent point of contact during consultation periods. His presentations at regulatory forums often combined survey statistics with practical examples drawn from operator submissions, giving attendees a clearer picture of how new rules would apply in day-to-day operations. That combination of data and operational insight has been cited by multiple trade bodies as a factor that eased the transition to tighter standards.

Looking Ahead

The Gambling Commission has stated that Miller's departure will not interrupt ongoing projects. Teams already working on the next wave of survey analysis and policy guidance will continue their work under interim leadership until a permanent replacement is appointed. External partners, including academics and treatment providers, have been invited to submit expressions of interest for future collaboration opportunities.

According to the official announcement, Miller's contributions have helped embed research more firmly within the commission's decision-making processes. The organization now maintains a dedicated evidence unit that reports directly to the board, a structure introduced during his time in post. This unit continues to produce quarterly updates that feed into both enforcement priorities and long-term strategic planning.

Conclusion

Tim Miller's scheduled departure in September 2026 closes a ten-year chapter at the UK Gambling Commission. His work on the Gambling Survey for Great Britain and the operational delivery of White Paper measures has left a measurable imprint on the regulatory environment. As he prepares for an international role, the commission moves forward with the research infrastructure and policy tools he helped develop, while preparing for the next round of reforms scheduled through the remainder of 2026 and into subsequent years. Further updates on succession planning are expected from the commission in due course, with the linked source providing the primary reference for the announcement details.
