How many slot machines are in the UK?

How many slot machines are there in the UK? The short answer

Gaming machines in Great Britain are counted by the Gambling Commission through the regulatory returns that licensed businesses send in, and it publishes the results sector by sector. Those statistics are the closest thing to an official count, but they cover licensed operators. Pubs and members' clubs run machines under permits and automatic entitlements issued locally, so a single tidy number for every machine in every venue is not something we have been able to verify.

What can be said with confidence is this: the two arcade sectors alone reported nearly 98,000 machines in 2023–24, so the national total is well above that; some sectors have shrunk sharply since the mid-2000s; and the largest reported group of cash-paying machines sits in adult gaming centres, the high-street arcades for over-18s. Northern Ireland has its own separate law, so most figures here are for Great Britain (England, Scotland and Wales).

UK slot machine numbers by venue

The 2005 figure comes from the explanatory memorandum to a 2006 order on gaming machine limits, and it shows how the market looked when most pub and arcade machines were still called AWPs (amusement with prizes). The 2023–24 arcade and FEC figures were published in the Commission's industry statistics and reported in December 2024. The 2025–26 premises figures come from the Commission's industry statistics release for 2025 to 2026 (opens in a new tab), which points to its data file for sector-level detail.

We have not been able to verify a current total for machines in pubs, members' clubs, bingo halls or casinos, so we don't quote one. If you see a single national figure elsewhere, check which sectors and which year it covers.

How many slot machines each UK venue is allowed

Even without a single national count, the law caps how many machines each type of premises may have. These limits, set mainly by section 172 of the Gambling Act 2005, explain why you see two machines in a pub but rows of them in an arcade.

The full rules, including transitional cases, are on our machine entitlements page and in the Commission's summary of machine provisions by premises (opens in a new tab). A 2:1 ratio of Category B machines to C and D machines for arcades and bingo halls was announced in May 2024, but it is not in force: the 20% cap still applies.

Worked example: the ceiling in betting shops

Betting shops are the easiest sector to estimate because the cap is a fixed number. With 5,617 shops in 2025–26 and a legal maximum of four machines each, the ceiling is:

• 5,617 shops × 4 machines = 22,468 machines at most.
• That is a maximum, not a count: some shops run fewer than four.
• Most of these are Category B2 or B3 machines with a £2 maximum stake.

Compare that with the 33,319 FOBTs counted in 2011–12, when there were more shops. The fall reflects shop closures, including those that followed the cut in the B2 maximum stake from £100 to £2 on 1 April 2019.

Which categories of slot machine are most common?

The category tells you the stake and prize limits, so it also tells you what most of Britain's machines are like. Category C and D machines are allowed in the widest range of venues, from pubs to seaside arcades, while Category B1 is limited to casinos. Arcade figures reported for 2023–24 show Category B3 machines produced £462.93 million of gross gambling yield in adult gaming centres, against £141.70 million from Category C, which suggests B3 machines are the main earners in that sector even though they are capped at 20% of machines.

Category A machines, with unlimited stakes and prizes, would only be allowed in a regional casino, and none exists, so there are no Category A machines in Great Britain. Our guide to UK slot machine categories lists every limit, and the gaming machine categories explained page covers where each may be sited.

How many online slot machines are there in the UK?

Online slots aren't counted as machines at all. They are games hosted on servers and offered by remote casino licence holders, and a single game can be played by thousands of people at once. Each large casino lobby typically lists games from dozens of studios, and new titles are added every week, so the number of online slots available to UK players runs into the thousands and changes constantly.

The Commission measures online slots by money, not units: online slots produced £4.8 billion of gross gambling yield in April 2025 to March 2026. Our page on how much people spend on slot machines in the UK explains what that figure means. For how the games themselves run, see how online slots work.

Why the number of UK slot machines has changed

1. 1968 to 2007: the Gaming Act 1968 divided machines into jackpot machines and AWPs, and pub and arcade AWPs made up most of the 235,000 counted in 2005.
2. 1 September 2007: the Gambling Act 2005 came fully into force and replaced that system with Categories A to D.
3. 13 July 2011: arcades and bingo halls moved from fixed limits (4 and 8 Category B machines) to a 20% cap.
4. 1 April 2019: the B2 stake cut to £2 reduced the value of machines in betting shops, and shop numbers have continued to fall since.
5. 22 July 2025: converted 1968 Act casinos could apply to run up to 80 machines, and small casinos moved to 5 machines per table.

Family entertainment centres show the long-term decline most clearly: 31,012 machines in 2008/09 against 11,666 in 2023–24. Arcades for adults went the other way in the most recent year reported, with numbers up 6%. Our history of slot machines in Britain covers the earlier decades.

Age rules and safer play on UK machines

All machines in Categories B and C are for adults aged 18 and over. Category D machines have no statutory minimum age at present, although the industry has applied a voluntary 18+ policy to cash-paying Category D slot-style machines since 2021, and the government has announced, but not yet brought in, an offence covering them. Arcade pages on this site are written for adults; see can under-18s play arcade machines.

Every machine costs more than it returns over time, and the house edge applies wherever you play. If you want to stop using machines in arcades or bingo halls, venue self-exclusion schemes exist; read can I self-exclude from arcades.
