UK Venues Face New Category B Machine Rules From June 2027

The UK Gambling Commission has confirmed new rules for land-based gaming machines, and the clock is now running. Most changes start on 30 June 2027, giving manufacturers and venues less than a year to prepare.

The rules follow a Gambling Commission consultation that received 1,065 responses. The Commission published its decisions on 30 September 2026.

What the new rules require

The changes apply to new Category B gaming machines. These are the higher-stake machines found in casinos, betting shops, adult gaming centres and bingo halls.

1. Better player tools. New machines must give players easier access to gambling management tools.
2. Session information. Players must be able to see how long they have played and how much they have won or lost.
3. Data for venues. Session information must also reach licensees, so staff can step in when a player shows signs of gambling harm.
4. Fairer game design. Machines must not celebrate wins smaller than the stake. Features that let players shorten the time until a result is known are banned.

Existing machines are exempt

The biggest relief for operators is the exemption. Machines already in use will not need upgrading, because the Commission judged the technical changes and costs too high for the benefit they would bring.

Many consultation responses raised cost concerns, and the exemption answers them directly. The rules will therefore spread gradually, as venues replace old machines with new ones.

The dates operators need to know

• 29 July 2026 (already in force): a licence condition requiring venues to remove non-compliant machines when the Commission tells them to.
• 30 March 2027: a new official definition of a gaming machine "session" takes effect.
• 30 June 2027: most other changes start for new Category B machines.
• 3 October 2028: staff alert requirements begin, after a longer lead time for the technical work involved.

What the changes mean for each group

Manufacturers and suppliers carry the heaviest load. New machine designs must include the session display, player tools and game design limits before the June 2027 date. Testing and approval timelines should start now.

Venue operators face less pressure, thanks to the exemption. Purchasing plans still matter, because every new machine bought after the rules apply must comply.

Venue staff will need training. Session data and, from 2028, staff alerts mean employees will be expected to notice and respond to players showing signs of harm.

The market at stake is large. Land-based gaming machines generated £2.6 billion in gross gambling yield between April 2024 and March 2025, with Category B machines making up 88.5% of that total.

How operators should prepare

• Check the exact cut-off. Read the full consultation response to confirm which machines count as existing and which count as new.
• Talk to suppliers early. Ask when compliant models will be ready and whether delivery dates fall before or after June 2027.
• Plan staff training. Prepare teams to use session data and respond to signs of harm, ahead of the 2028 staff alert rules.
• Review machine replacement plans. Older machines stay legal, but every replacement brings the new rules onto your floor.
• Keep removal procedures ready. The July 2026 licence condition means venues must act quickly when the Commission flags a non-compliant machine.

What to watch next

Watch for updated technical standards documents, testing guidance for manufacturers and any changes to the staff alert design. Online operators should also follow closely, since session information and player tools are already standard in remote gambling rules.

For UK land-based operators, the message is clear. Existing machines buy time, but every new purchase from June 2027 brings the new rules with it.
