Tim Miller will leave the UK Gambling Commission in September 2026 after 10 years at the regulator. Miller is Executive Director of Policy and Research and has held senior roles during a period of major changes to gambling rules in Great Britain.
The Commission announced the departure on June 29. It has not yet named a successor or confirmed who will take over Miller’s policy and research responsibilities.
Miller joined Commission in 2016
Miller joined the Gambling Commission’s executive team in 2016. He later became Executive Director of Insight and Safer Gambling before moving into his current Policy and Research role.
During his time at the regulator, Miller worked on safer gambling policy, consumer protection measures, research and changes linked to the Gambling Act review. He was also involved in the Commission’s work on affordability checks, deposit limits and operator duties.
Miller regularly represented the Commission at industry conferences, parliamentary sessions and public consultations. He became one of the regulator’s most visible senior executives during debates over gambling reform.
Other senior changes
Miller’s exit comes after several changes in the Gambling Commission’s senior team. Former chief executive Andrew Rhodes left the regulator on April 30, 2026, and Sarah Gardner became acting chief executive.
Sue Young joined the Commission as Executive Director of Operations in March. The regulator is also changing its senior team as it prepares for new rules and funding changes. The Commission is responsible for licensing and regulating commercial gambling in Great Britain. Its remit includes online betting, casinos, bingo, gaming machines and the National Lottery.
Work on new rules continues
The regulator is still working on several major policy areas. These include new deposit limit requirements, financial risk checks, gambling marketing controls and updates to technical standards for online gambling products.
Operators have been given more time to prepare for some of the new deposit limit rules. The Commission is also consulting on how gambling regulation should be funded and has asked the industry for ideas to reduce unnecessary regulatory burdens.
Miller will remain at the Commission until September. His departure will come as the regulator continues to implement changes linked to the government’s gambling reform programme.
