Tim Miller Steps Down from UK Gambling Commission After Decade of Leadership

The UK Gambling Commission has confirmed that Tim Miller, its Executive Director of Policy and Research, will depart the organisation in September 2026 after serving ten years in the role. Miller's exit comes as he prepares to assume an international position focused on supporting gambling regulation in jurisdictions outside the United Kingdom. The announcement, issued through official channels, highlights a structured transition period that observers expect will run through the summer months of 2026.

Contributions Across a Decade of Regulatory Development

Miller joined the Commission in 2016 and quickly became central to efforts that expanded the regulator's evidence base. Colleagues credit him with building internal research capacity that allowed the organisation to draw on more robust data when shaping policy. This work included the creation of new analytical frameworks that examined player behaviour across both land-based and online environments, and those frameworks remain in active use today.

One of the most visible outcomes of this focus arrived with the launch of the Gambling Survey for Great Britain. The survey replaced earlier data collection methods and introduced a larger, more representative sample that continues to inform annual statistics releases. Researchers note that the survey's design improved comparability across different gambling formats, while its ongoing publication schedule provides regular updates on participation rates and harm indicators.

Implementation of White Paper Reforms

Miller played a direct part in translating recommendations from the Gambling Act Review White Paper into operational measures. The reforms addressed several long-standing areas, including strengthened age-verification protocols for online accounts, the introduction of financial risk checks for higher-spending customers, and expanded safer-gambling messaging across licensed operators. Commission records show that these changes moved through consultation and implementation phases between 2023 and 2025, with Miller's team coordinating the research strands that underpinned each requirement.

During July 2026 the Commission is expected to publish its latest progress report on these same measures. The report will cover compliance rates among operators and early data on the impact of financial checks, and Miller's involvement in drafting elements of that document forms part of his remaining responsibilities before departure.

Transition and International Move

The Commission has stated that recruitment for Miller's successor is underway, with the process designed to ensure continuity in the policy and research directorate. Existing staff members will handle day-to-day operations during the handover, while external advisers have been engaged to support the incoming director. Miller himself will leave on 30 September 2026 and immediately begin work in his new international capacity, which focuses on regulatory capacity-building in markets that are still developing their own oversight structures.

Official statements emphasise that Miller's international role will not involve direct engagement with UK-licensed operators, thereby avoiding any conflict-of-interest concerns. The move reflects a broader pattern in which senior regulators take on advisory positions that share technical expertise across borders.

Looking Ahead

The period between now and Miller's departure provides the Commission with several months to embed ongoing projects and document institutional knowledge. Observers note that the combination of the Gambling Survey's established methodology and the White Paper reforms already in force creates a stable platform for the next phase of regulatory work. The Commission has indicated that updates on the recruitment process will appear on its website as milestones are reached, allowing stakeholders to follow developments through the remainder of 2026.
