New UKGC Gaming Machine Rules: Mandatory Safety Features from June 2027

The UK Gambling Commission (UKGC) has confirmed significant changes to gaming machine safety standards, with the main requirements taking effect on 30 June 2027. Announced on 30 September 2026, the rules will introduce mandatory spending and time limits, clearer information about gambling losses, compulsory breaks and restrictions on certain game features. They primarily affect new gaming machines and games in land-based gambling venues across Great Britain. The changes also include a revised definition of a gaming session from March 2027 and additional staff alert requirements from October 2028. Here is what will change, which machines are affected and what players and operators should expect.

Which UKGC Gaming Machine Rules Will Change in June 2027?

The reforms follow the government’s 2023 Gambling Act Review White Paper and a UKGC consultation launched in January 2025. More than 1,000 consultation responses helped shape the final requirements, published on 30 September 2026. The resulting amendments to the Gaming Machine Technical Standards (GMTS) aim to help customers recognise how long they have been gambling, understand their financial position and make more informed decisions about continuing. They also address misleading game presentation and features that can increase the pace of gambling.

The most substantial changes apply to new Category A, B1, B2, B3, B3A and B4 machines and games. These categories cover various types of higher-prize gaming machines, including machines permitted in casinos, betting shops, bingo premises and adult gaming centres. Some restrictions on game design will also apply to new Category C machines and games. The exact requirements depend on the machine category and the specific technical standard, so the June 2027 reforms should not be interpreted as identical obligations for every gaming machine in Britain.

Importantly, existing machines are generally exempt from the new safety features in GMTS Section 15, following concerns about the cost and practicality of upgrading older equipment. However, a game or machine may be classified as new if its relevant testing documentation is dated 30 June 2027 or later, including after certain modifications that could affect game fairness or randomness. Manufacturers cannot simply assume that an older cabinet will remain exempt after substantial software changes. The classification depends on the UKGC’s published testing guidance.

Three Implementation Dates That Operators Must Know

The first milestone is 30 March 2027, when the revised definition of a gaming machine session becomes effective. This establishes how a session is identified for purposes such as recording elapsed time, calculating financial results and applying the new safeguards. The UKGC introduced this measure earlier than the other changes to allow session data to be collected under a consistent definition before the main requirements begin. This also helps avoid unnecessary interruptions before a customer has actually started playing.

The principal deadline is 30 June 2027. From that date, the updated technical standards will require qualifying new machines and games to provide limit-setting functionality, customer alerts, safer gambling information and session tracking. Restrictions on celebrating returns that do not exceed the stake and features that shorten the time until a result appears will also take effect. The updated Gaming Machine Testing Strategy and relevant amendments to the Licence Conditions and Codes of Practice will become effective on the same date.

The final major deadline is 3 October 2028, when additional staff alert requirements under GMTS 15.1d and the corresponding social responsibility code provision will become mandatory. Operators will need appropriate arrangements for responding to alerts about certain customer limits being reached or changed. The longer implementation period reflects the technical work involved in connecting gaming machines with staff notification systems. Although these alerts are not mandatory until October 2028, the UKGC encourages businesses to introduce suitable arrangements earlier where practicable.

Mandatory Time Limits, Loss Controls and Player Information

One of the most noticeable changes will appear before a qualifying customer begins a gaming session. New machines covered by GMTS 15.1 must require an active choice between customer-defined and default limits for both playing time and monetary losses. A player cannot select an unlimited option. The machine must give equal prominence to entering an individual limit and choosing the default. This is designed to prevent the presentation of choices from steering customers towards higher spending or longer sessions.

The default limits at the beginning of a session cannot exceed 20 minutes of play and a net loss of £150. Customers who prefer to set their own limits may choose up to 60 minutes and a maximum net loss of £450. These are regulatory ceilings, not recommended gambling budgets or fixed amounts that every machine must offer. Operators may provide lower defaults or suitable choices within the permitted range. The financial limit is based on net losses, meaning winnings are taken into account rather than treating every individual stake as a separate loss.

Customers may continue playing after a compulsory break by selecting further limits, subject to the rules governing the next period of play. New customer-defined time limits cannot exceed another 60 minutes, while new default time limits cannot exceed another 20 minutes. Further monetary limits are also restricted, with different calculations depending on whether the player is ahead or behind overall. Importantly, the regulations do not introduce a universal £450 lifetime or daily loss cap. Instead, they establish maximum limits for individual stages of a gaming session, alongside mandatory interruptions.

Breaks in Play, Safer Gambling Messages and Session Tracking

When a customer reaches a selected limit, the machine must issue a real-time alert and interrupt play. The first default time limit triggers a break lasting at least 10 seconds, while the second triggers a break of at least 20 seconds. These shorter interruptions apply specifically when the customer chose default time limits at the beginning of the session. Other qualifying interruptions, including those associated with customer-defined limits, must last at least 30 seconds. Changing a limit before reaching it must also produce an alert and a break, preventing customers from adjusting restrictions without interruption.

During these breaks, qualifying machines must show information about safer gambling, explain why play has stopped and provide appropriate details about the current session. Customers should have access to sources of further help and information and be able to end their session or choose further limits. Promotional material intended to encourage additional gambling must not appear during these compulsory interruptions. The purpose is to give players an opportunity to assess their decisions rather than filling the pause with advertising or encouragement to continue.

Another requirement is the display of elapsed time and the player’s net financial position. On qualifying new machines, this information must be visible by default, although customers must be allowed to hide it. Elapsed time is shown in hours, minutes and seconds, while net position reflects winnings minus losses during the session. For example, if a player has lost £80 and won £25, the displayed net position would be minus £55. This gives a clearer picture than the current credit balance alone. The rules also address mixed-game machines, ensuring relevant session information remains accessible when customers move between games.

Changes to Slot Features, Machine Design and Operator Duties

The UKGC is also changing how gaming machines communicate results. From 30 June 2027, new machines and games in Categories A, B1, B2, B3, B3A, B4 and C must not celebrate a return that is less than or equal to the amount staked. For example, if a customer stakes £2 and receives £1.50 back, the machine must not present that result with celebratory sounds or visual effects normally associated with a win. The same restriction applies when the return equals the £2 stake. The machine can still show the amount returned and use a brief sound to communicate the result.

Another change prohibits features that allow customers to reduce the time until a game’s result is presented. The UKGC specifically identifies turbo, quick spin and slam stop as examples of prohibited functions. The restriction applies to new machines and games in Categories A, B1, B2, B3, B3A, B4 and C. It aims to reduce the intensity of gambling and discourage the impression that pressing a stop button can influence an outcome that has already been determined. The prohibition does not apply in the same way to bonus or feature games where no additional stake is wagered.

These provisions concern the design and presentation of gambling rather than changing the underlying odds of winning. A machine that removes celebratory effects for losing outcomes does not automatically become more generous, and disabling quick-spin functions does not increase the probability of winning. Instead, the measures address how players experience results and how rapidly they can participate in consecutive games. Clearer information should make it easier to distinguish a genuine profit from a partial return, especially during longer sessions.

What Players, Casinos and Manufacturers Should Prepare For

For players, the most practical change will be the need to select limits before starting qualifying new machines and to acknowledge interruptions when those limits are reached. Session information should also become easier to understand. Customers who do not want their time and financial position continuously visible will have the option to hide that information, although the required safeguards and break notifications will still apply. Existing machines may continue operating under the relevant older standards, meaning the changes will not necessarily appear across every gambling venue on the same day.

Manufacturers and software suppliers will need to review game menus, limit-setting controls, session records, result animations and game-speed functions against the updated standards. Operators should establish which machines qualify as new, confirm the status of testing documentation and assess whether mixed-game cabinets require wider changes. The revised testing requirements make the distinction between existing and new games particularly important. Changes that affect fairness or randomness may bring previously existing equipment within the scope of the new obligations following testing or retesting.

Casinos, betting operators, bingo businesses and adult gaming centres should also prepare staff procedures for the later alert requirements and ensure employees understand the information available to support customer interactions. The UKGC’s September 2026 decision creates a phased regulatory timetable rather than a single nationwide replacement of gaming machines. By 30 June 2027, newly qualifying machines will need to offer clearer loss and time information, meaningful breaks and less misleading gameplay presentation. The longer-term aim is to give customers greater awareness of their gambling while making safer play a built-in part of machine design.
