Latest UKGC Updates 2025: Changes Impacting New Casinos

As is often the case, 2025 is shaping up to be a busy year for the UK gambling industry, with several legislative changes set to impact new casinos and how players interact with them. 


Marketing Consent Rules (Effective 1st May 2025)

Operators will be required to provide specific opt-in options for marketing communications, segmented by:

  • Channel (e.g) email, push notifications, SMS
  • Type of gambling (e.g) casino, sports betting, bingo

Customer Tools & Financial Limits (Effective 31st October 2025)

New players must be prompted to set deposit or spending limits before making their first deposit.

Operators must prompt players to review account activity and limits every six months.

The level of player fund protection - (e.g) high medium or no protection - must be clearly explained.


Responsible Gambling Incentives (Effective 19th December 2025)

The UKGC will introduce stricter rules around promotional offers to ensure they support responsible gambling - key changes will include:

  • Wagering requirements on bonus will be capped at 10x the bonus amount
  • Cross-product incentives - (e.g) casino and sports combined - will no longer be allowed in a single offer
  • Operators cannot require players to gamble for a fixed time period or frequency as part of a bonus promotion
