Phil Walker will become interim chief executive of Allwyn UK on 7 September 2026. He will replace Andria Vidler as the National Lottery operator begins its next phase of digital growth, product development and player protection.

Allwyn announced the leadership change on 19 August. Vidler will remain available in an advisory role until the end of October. She will support Walker and Allwyn UK chair Justin King during the handover.

Betting-sector experience

Walker joins Allwyn after six years at William Hill. His previous roles included online managing director, managing director for the United Kingdom and Ireland, and chief commercial officer.

Allwyn said Walker has experience in digital, commercial and operational transformation. He will oversee the National Lottery’s retail network, website, app and expanding online product range.

Walker’s appointment places a former betting executive at the centre of the National Lottery’s next growth phase, under continued Gambling Commission oversight.

From licence transition to expansion

Vidler led Allwyn UK during the transition from Camelot to the Fourth National Lottery licence. The transition began on 1 February 2024.

The Gambling Commission awarded Allwyn Entertainment Ltd a 10-year licence. It runs until 31 January 2034.

Allwyn said it has invested £450 million in the National Lottery’s transformation. The programme included technology and infrastructure upgrades for 43,500 retail partners, along with major changes to the website and app.

The company also said it added one million active digital users, relaunched Lotto and introduced Powerball in Great Britain.

According to Allwyn, the technology programme included more than 30 new systems and the migration of millions of transactions. In August 2025, the operator completed a 34-hour shutdown of National Lottery systems and terminals for its largest upgrade since the lottery launched in 1994.

Regulatory pressure remains

Digital growth is only one measure of the new phase. The Fourth Licence requires Allwyn to protect participants, maintain propriety and maximise returns to Good Causes.

The Gambling Commission uses an outcomes-based model for the licence. This gives Allwyn greater responsibility for meeting those obligations while preserving the regulator’s power to intervene.

The Commission has made several 2026 licence decisions affecting Allwyn’s product range. They include the introduction of Powerball on 21 July and a pilot for £10 Scratchcards beginning in September, subject to specified controls.

Walker’s interim tenure begins with competing demands. Allwyn must attract and retain digital players, develop products and continue investing in its retail network while meeting requirements on player protection and returns to Good Causes.

What changes next

  • Phil Walker becomes interim chief executive on 7 September 2026.
  • Andria Vidler remains available in an advisory capacity until the end of October.
  • Allwyn continues its search for a permanent successor.
  • The company’s stated priorities include digital transformation, growth, product development and participant protection.

The leadership change does not alter Allwyn’s licence. Allwyn Entertainment Ltd remains the licensed National Lottery operator in Great Britain until 31 January 2034, under Gambling Commission oversight.
