Online slot stake limits
Since 2025 there is a legal ceiling on what you can stake per spin on an online slot in Great Britain. It is age-banded, it applies to slots specifically, and it is one of the more concrete things to come out of the 2023 gambling White Paper.
The limits at a glance
- Aged 25 and over
- £5 maximum per spin, from 9 April 2025
- Aged 18–24
- £2 maximum per spin, from 21 May 2025
- Applies to
- online slots on GB-licensed sites
- Does not apply to
- sports betting, table games, bingo, lottery
- Set by
- the 2023 White Paper reforms
What the limits are
Two caps apply to online slots on sites licensed by the Gambling Commission. Players aged 25 and over cannot stake more than £5 per spin, a rule that took effect on 9 April 2025. Players aged 18 to 24 face a lower cap of £2 per spin, in force since 21 May 2025. The lower band reflects evidence that younger adults are more exposed to gambling harm.
Both are hard limits enforced by the operator, not guidance. A licensed site cannot let you exceed them, whatever your account history or balance.
Why slots specifically
The reforms singled slots out as the product carrying the highest risk of harm: fast, continuous, solitary play with no natural break between rounds. Sports betting has an event to wait for; a slot does not. That is the reasoning behind capping the stake rather than, say, the session length.
It also means the cap is narrower than people often assume. It does not cover sports betting, live or RNG table games, bingo or lottery products, and it does not cover land-based machines, which sit under a different set of category rules.
What the cap does not do
- It does not limit how much you can lose. A £5 cap with fast spins still adds up quickly; the limit shapes the size of each bet, not the total.
- It does not change the RTP of any game. Return to player is a property of the title, and a lower stake simply scales the amounts up and down.
- It does not replace your own limits. Deposit and loss limits in the account are still the tool that actually controls spend — see responsible gambling.
Sites that ignore the cap
Offshore sites without a Gambling Commission licence are not bound by any of this, and some advertise that fact. What they also are not bound by: GAMSTOP, the complaints framework, and the requirement to keep customer funds separate from operating money. The cap is one thread in that fabric, not a standalone rule worth going round — see what GAMSTOP is.
Checking a site is covered
The Gambling Commission publishes a public register of licensed operators. If a site is on it, these limits apply to its slots; if it is not, nothing on this page does. See what a UKGC licence actually means.
