Online slots stake limits have applied in Great Britain since spring 2025: £5 per game cycle for adults aged 25 and over and £2 for those aged 18 to 24. This 2026 guide explains the rules in SI 2025/215, the evidence DCMS used to set them, what the government expected them to cost operators and what Gambling Commission data have shown since they took effect.
What the online slots stake limits rules say
The limits come from the Gambling Act 2005 (Operating Licence Conditions) (Amendment) Regulations 2025, numbered SI 2025/215. The instrument was made on 25 February 2025 under section 78 of the Gambling Act 2005 and adds a new condition to every remote casino operating licence.
The condition caps the total amount an individual may stake on any game cycle of an online slots game at £2 for anyone under 25 and £5 for anyone aged 25 or over. A game cycle runs from the start of a game until all money staked has been lost or all winnings have been paid, so extra stakes within the same cycle count towards the cap.
According to the Gambling Commission, the £5 slot limit for all adults went live on 9 April 2025 and the £2 limit for 18 to 24 year olds on 21 May 2025. In between, a six-week transitional period applied the £5 cap to everyone so that operators could make the technical changes.
Key point: the maximum stake online slots rule covers reel-based games only. The Commission confirms that roulette, blackjack and other casino games are not capped by it.
Online slots are the largest single product in the online market, as our UK gambling industry statistics guide shows. The condition binds GB-licensed operators only, so casinos outside GamStop that hold no Commission licence are not covered by it, and the Commission treats offering gambling to people in Britain without a licence as illegal.
Why 18-24s face a lower limit
A stake limit for online slots was first promised in the April 2023 High Stakes white paper, whose full title is “High Stakes: Gambling Reform for the Digital Age”. DCMS then consulted from 26 July to 4 October 2023 on general limits of £2, £5, £10 or £15 per game cycle, and on a £2 limit, a £4 limit or case-by-case checks for young adults.
The consultation-stage impact assessment cited a problem gambling rate of 1% among 16 to 24 year olds, against a headline rate of 0.3%, in Commission survey data for the year to March 2023. It also pointed to research showing that brain development continues up to the age of 25.
Young adults are not the heaviest online players, though. Commission data from May 2023, quoted in the same assessment, showed that 13.5% of 16 to 24 year olds had gambled online in the past four weeks, the lowest share of any adult age group, a pattern our guide to how many people gamble in the UK explores with newer survey data.
Patterns of Play data in the assessment found that 18 to 24 year olds already staked about 20% less than the average adult. DCMS therefore judged that a £2 stake limit 18-24 rule would be less disruptive for this group than it would be as a general limit.
The consultation received 96 responses, plus survey results from 3,898 members of 38 Degrees and a Gambling With Lives petition signed by 12,775 people. Most industry respondents backed a £10 limit, while 60% of respondents favoured £2 or less for 18 to 24 year olds.
- April 2023: the Gambling Act review white paper, High Stakes, proposes a statutory limit for online slots.
- 26 July to 4 October 2023: DCMS consults on the options.
- February 2024: the government response confirms £5 for over-25s and £2 for 18 to 24 year olds.
- 25 February 2025: SI 2025/215 is made.
- 9 April 2025: the £5 limit applies to all adults.
- 21 May 2025: the £2 limit applies to 18 to 24 year olds.
The evidence: who staked more than £10 a spin
The case for a cap rested on how concentrated high stakes were. Before the limits, the DCMS impact assessment found that most operators offered stakes of up to £50 per spin, and the highest it was aware of was £500.
Industry data in the assessment covered almost 76.8 billion spins from April 2022 to March 2023. Only 2.9% of spins were above £2, 0.6% above £5 and 0.09% above £10, yet there were still 797,000 staking events above £50 and 109,000 above £100.
Most stakes were small even among risky players: 87% of stakes by high-risk accounts and 93% by medium-risk accounts were below £2. However, high and medium-risk accounts placed 37.4% of stakes over £10, although only 2.4% of players were flagged in those groups.
The assessment also flagged a risk that some constrained play could move to the unlicensed sector. Such offshore casinos sit outside the Commission’s rules, and it cited a European Commission estimate that the UK black market for sports betting was 2.2%.
What the limits were expected to cost operators
The explanatory memorandum estimated that the limits would cut online casino GGY by 5.6% against what would otherwise have happened, about £164.8m in the first year. Operators also faced one-off costs to test and deploy limits on live games.
The earlier impact assessment compared the options in its table 7. The chosen combination of a £5 limit with £2 for 18 to 24 year olds had a central estimate of £138.8m a year, far below the cost of a flat £2 limit.
| Option modelled (2023) | Central GGY reduction | Range |
|---|---|---|
| Flat £2 limit | £328.5m | £243.5m to £413.5m |
| £5 limit, £2 for 18 to 24 | £138.8m | £99.2m to £178.3m |
| £10 limit, £2 for 18 to 24 | £55.0m | £32.8m to £77.1m |
The models assumed that 15% to 30% of affected spending would simply move to other online casino games. They also estimated that 18 to 24 year olds accounted for 5.58% of online slots spend.
The assessment put online slots GGY at £3.00bn in the year to March 2022, up from £1.56bn in the year to March 2016, with slots worth 47% of remote GGY in 2021/22. Stake limits arrived alongside higher duties, explained in our UK gambling tax article.
What the data show since April 2025
Gambling Commission statistics suggest the market absorbed the change. Online slots GGY was £4,789.6m in 2025-26, the first financial year under the limits, up from £4,148.0m in 2024-25, while slots turnover rose to £93,951.8m.
Monthly operator data do show a short-term effect. Slots sessions lasting more than an hour fell 23.4%, from 3.66 million in March 2025 to 2.80 million in April 2025, and active slots accounts fell 7.9% between March and June 2025, from 4,740,347 to 4,365,676.
By December 2025 active accounts had reached 4,918,471, a record for the series, as our online slots statistics UK article shows. The rise cannot be credited to or blamed on online slots stake limits alone, because tax, marketing and game design changed in the same period.
Payment rules shape the market too. GB-licensed operators have not been allowed to accept credit cards since April 2020, so casinos that take credit card payments from UK players are licensed elsewhere and fall outside the stake limit as well.
How operators apply the age split
A two-tier £5 slot limit depends on knowing each customer’s age. Commission rules already require GB licensees to verify a customer’s age before they can gamble, so operators set the cap from the date of birth on the account.
Because the condition is based on age, a customer’s maximum rises from £2 to £5 on their 25th birthday. The explanatory memorandum says the six-week gap between the two stages was there to give operators time to make the necessary technical changes.
The limit works alongside the Commission’s game design rules from October 2021. These require at least 2.5 seconds between the start of one game cycle and the next and ban losses disguised as wins, so the rules now restrict both the size and the speed of each spin.
- Covered: online reel-based slots offered by GB remote casino licensees.
- Not covered: online roulette, blackjack and other casino games.
- Separate rules: gaming machines in shops, arcades and casinos, which have their own stake limits.
Age checks are also why the limit cannot be applied by unregulated sites. Casinos without ID checks do not follow the GB verification rules, so they have no reliable way to apply an age-based cap.
How the limits compare with the B2 FOBT £2 cut (2019)
The closest precedent is the B2 FOBT £2 cut (2019). In April 2019 the maximum stake on B2 gaming machines in betting shops fell from £100 to £2.
The DCMS assessment recorded a 99% (£1.16 billion) fall in B2 GGY after the cut and a 29% fall in overall gaming machine GGY. Commission data show B2 GGY in betting shops falling from £1,152.8m in 2018-19 to £6.7m in 2019-20, while B3 GGY rose from £671.5m to £1,068.9m as machines were switched over.
SI 2025/215 also contains its own review clause. The Secretary of State must publish a first review of the condition within five years of it coming into force, and further reviews at intervals of no more than five years.
