UK Gambling Commission Confirms Technical Standards for New Category B Gaming Machines

The UK Gambling Commission has confirmed new technical standards for newly released Category B gaming machines, including slots and fruit machines found in betting shops, adult gaming centres, and casinos, and these updates follow a 2025 consultation process that gathered input from industry stakeholders and regulators alike.

Operators must now incorporate mandatory access to session information such as play duration along with wins and losses, while personal spending and time limits come with default settings built into the software, and responsible game design rules prohibit celebrations for sub-stake wins plus features that accelerate results like turbo spins.

Core Requirements Outlined in the Standards

Session data must display clearly to players during gameplay, and this feature helps users track their activity in real time without needing external tools or requests to staff, whereas personal limits allow individuals to set boundaries on expenditure and duration with automatic defaults applied unless adjusted by the user.

Game design rules target elements that might encourage extended play, so machines cannot highlight wins below the original stake amount, and any mechanisms speeding up reel results face outright bans under the new framework.

Phased Rollout Timeline

Implementation occurs in stages beginning March 2027 when the session definition takes effect, followed by most technical rules activating in June 2027, and staff alert systems becoming mandatory by October 2028.

Existing machines receive exemptions because retrofitting them presents significant technical and financial hurdles for manufacturers and venue operators, and this approach allows focus on new releases that can integrate the requirements from the design stage onward.

Industry Preparation and Compliance Steps

Manufacturers have started adapting their development pipelines to meet the deadlines, and they work closely with software providers to embed the required data displays and limit controls into upcoming models, while venue staff receive training materials ahead of the October 2028 alert system deadline.

By October 2026 operators will review their procurement plans for new machines to ensure compliance readiness, and this preparatory phase gives companies time to test prototypes against the commission's specifications without disrupting current operations.

According to coverage from iGamingBusiness the standards align with proposals from the 2023 Gambling Act Review White Paper, and the response to consultation on new Gaming Machine Technical Standards details how these measures support player information access across licensed premises.

Scope and Exemptions Explained

Only newly released Category B machines fall under the updated rules, so older equipment continues under previous standards until replacement occurs through natural fleet turnover, and this distinction prevents widespread hardware replacements that could strain smaller operators.

Betting shops, adult gaming centres, and casinos all see the same core requirements applied to their Category B offerings, although each sector may adapt display formats slightly to fit venue layouts and player interaction styles.

Conclusion

The confirmed standards establish clearer player tools and design boundaries for future Category B machines across the UK, with phased dates providing structured timelines for adoption and existing equipment remaining unaffected due to practical constraints.
