Tim Miller Announces Departure After a Decade at the Regulator

Tim Miller, Executive Director overseeing policy and enforcement at the UK Gambling Commission, has announced that he will step down in September. Miller confirmed his departure in a public statement, describing his ten years at the regulator as the most fulfilling period of his career.

He joined the Commission in 2016 under then Chief Executive Sarah Harrison. His mandate included strengthening the use of research and evidence in gambling regulation and improving oversight of licensed operators. Over the following decade, he became a central figure in shaping policy direction and enforcement strategy.

Miller stated that he had always viewed ten years as the right point to seek a new challenge. He indicated that his next role will involve international work with governments, regulators, and organizations focused on developing well regulated and competitive markets. Further details are expected after his final day at the Commission.

Departure Comes Amid White Paper Implementation

Miller’s resignation takes place during a period of significant regulatory change in the UK gambling sector. The Gambling Act review White Paper, published in 2023, set out a series of reforms described as generational in scope. The Commission is responsible for implementing many of these measures.

Several changes relating to bonuses and marketing practices are already in place. However, Financial Risk Assessments, commonly referred to within the industry as affordability checks, have not yet been fully implemented. These assessments are among the most debated elements of the reform package and continue to face opposition from parts of the betting industry and from horse racing stakeholders.

At the same time, the sector is adjusting to a new tax regime introduced in April of this year. Operators are therefore navigating both fiscal and compliance changes while awaiting the final shape of the affordability framework.

Miller will leave before the full rollout of Financial Risk Assessments. His departure removes a senior policy figure at a time when detailed regulatory design and supervisory oversight remain ongoing.

Focus on Illegal Gambling and Big Tech Advertising

In parallel with White Paper reforms, the Gambling Commission is engaged in efforts to address illegal gambling. It works alongside the government’s Illegal Gambling Taskforce to tackle unlicensed operators and related risks to consumers.

During the latter part of his tenure, Miller spoke publicly about the role of major technology platforms in the spread of illegal gambling advertising. He criticized companies including Meta for failing to prevent unlicensed operators from promoting services on mainstream social media platforms such as Instagram, X, YouTube, and Kick.

In a recent industry podcast appearance, Miller stated that insufficient action by large platforms undermines broader enforcement efforts. His comments reflected the Commission’s position that combating the black market requires cooperation beyond licensed operators and regulators.

At the same time, some licensed industry figures, including executives from Entain and Flutter Entertainment and representatives of the Betting and Gaming Council, have criticized what they view as limited progress in curbing illegal gambling. This places the regulator under pressure from both enforcement and industry perspectives.

Leadership Changes at the Gambling Commission

Miller’s exit follows the departure of Chief Executive Andrew Rhodes four months earlier. The Commission is therefore operating without a permanent Chief Executive, Chair, or Director of Policy during what it has described as one of the most critical phases in UK gambling regulation.

Sarah Gardner, Acting Chief Executive, acknowledged Miller’s contribution and described his service as outstanding. She highlighted his decade of involvement in shaping regulatory policy and oversight.

Among Miller’s projects was the establishment of the Commission’s Digital Advisory Panel, designed to improve understanding of emerging technologies and support the overhaul of digital systems. He also championed the development of GamProtect, a cross operator data sharing initiative intended to create a single customer view. Through this system, participating licensees can identify and voluntarily restrict customers who show severe indicators of gambling related harm.

Before joining the Commission, Miller held several public sector roles, including positions at The Law Society of England and Wales, the Parliamentary and Health Service Ombudsman, and the Local Government and Social Care Ombudsman. He also served on the Advisory Board for the Centre for Governance and Scrutiny.

Regulatory Settlement Period and Industry Adjustment

Earlier this year, Miller stated that the sector would require a settlement period to adapt to the compliance measures introduced through the White Paper. He noted that the industry needed time to move away from what he described as a regulatory treadmill.

For operators and users, this transition period is marked by evolving compliance requirements, ongoing debates around affordability checks, and intensified scrutiny of marketing and customer protection measures. The regulator’s ability to implement these changes consistently will be closely observed by licensed companies and market participants.

Our Assessment

Tim Miller’s departure removes a senior policy and enforcement leader during a phase of structural reform in UK gambling regulation. The Commission continues to implement White Paper measures, address Financial Risk Assessments, and coordinate action against illegal gambling, while operating without a permanent Chief Executive, Chair, or Director of Policy. For licensed operators and users, the leadership transition coincides with ongoing regulatory and compliance adjustments that remain in progress.
