From 30 September 2026, every licensed online casino must count deposit limits the same way.
Most people in Britain already live with a handful of spending caps: a contactless ceiling, a daily cash withdrawal limit, a monthly transfer limit in a banking app. Each one is defined precisely enough that you know where you stand. Online casino accounts carried a similar-looking control for years, but the sum behind the word differed from site to site, and on some of them cashing out winnings quietly handed you room to pay in again.
The Gambling Commission settled the question in October 2025 and gave operators until 30 September 2026 to rebuild their cashiers around one definition. So what does that definition include, and what does it leave out? Let's take a look.
What Counts Towards a Deposit Limit
Under the technical standards that apply to remote gambling in Great Britain, a deposit limit means the gross amount paid into an account over a chosen period. Money leaving the account has no effect on that figure. A player with a £100 monthly cap who pays in £60 and later withdraws £40 has £40 of their allowance left for the month, not £80. Only a control built on that calculation may carry the name, and licensed sites have to describe it to customers using exactly that name.
The payment method behind a top-up changes nothing about the count. Whether the money comes off a debit card, out of a bank app, from an e-wallet or through a phone bill at casinos where you can deposit by text, it lands in the same total against your cap. That means ten payments of £10 use up as much of your cap as a single £100 transfer.
Deposit, Loss and Stake Limits Are Not the Same Thing
Online casinos are free to offer other financial controls alongside the required one, and the differences between them are easy to miss when the options sit next to each other on the same settings page. A net deposit limit takes withdrawals off the total, so cashing out winnings frees up room to pay in again. A loss limit looks at stakes minus returns. A stake limit counts everything wagered, whether the bets land or not.
Choosing between them comes down to what you want to keep under control. A gross cap holds your outgoings to a set figure. A loss or stake control lets far more money move through the account, because winnings can be recycled into fresh bets without touching your bank balance.
One more difference rarely gets mentioned: only the gross version has to run on fixed periods, where a week restarts on a set day. The optional controls may run on rolling periods, which always look back over the previous seven days from whichever day you check.
• Deposit limit: counts money paid into the account; required at every licensed site; fixed periods only
• Net deposit limit: counts deposits minus withdrawals; optional extra; fixed or rolling periods
• Loss limit: counts stakes minus returns; optional extra; fixed or rolling periods
• Stake limit: counts total staked, win or lose; optional extra; fixed or rolling periods
Where a casino offers several of these, the gross cap has to appear with at least equal prominence to the rest, so it cannot be tucked away behind a more permissive option.
What Happens When You Reach the Cap
Once the allowance is used up, the system has to block further payments until the period restarts or you raise the figure yourself. Raising it takes time by design. The request only takes effect after a cooling-off period of at least 24 hours, and you then have to confirm it with a second, deliberate action once that time has passed. A request to lower a cap works the other way and applies immediately.
That asymmetry carries most of the value. Deciding on a budget and acting on the urge to exceed it tend to happen in different moods, and a full day sits between the two. Anyone who has raised a limit mid-session and regretted it the next morning will recognise why the delay exists, and the wording in the current technical standards leaves operators no room to waive it.
Daily, Weekly and Monthly Caps Work Together
The periods on offer have to include 24 hours, seven days and one month. Many people set two or three at once without working out how they interact, and the rule is that the most restrictive one always wins.
The regulator's own worked example makes this concrete. Someone who sets £10 a day alongside £100 a week ends up with £10 a day and £70 a week, because seven daily allowances never add up to the weekly figure. A weekly figure higher than seven times the daily one has no effect at all, which is worth checking if you assumed the larger number gave you headroom at the weekend.
The Limit Stops at the Edge of Your Casino Account
The smallest scope a site may apply is the account itself, though some also let you set caps on individual products or sections. Where both exist, the cashier has to make clear which of the two you are adjusting, so a figure attached to one game does not leave the rest of the account uncovered without you noticing.
A cap agreed with one operator has no bearing on an account held elsewhere, and opening that second account starts the count from zero. What the shared definition does give you is portability of the decision rather than the setting: the same monthly figure now means the same thing in every cashier you use, which was one of the stated reasons for standardising the term.
Ceilings on the payment side work the other way round. Phone bill top-ups are capped by the mobile network rather than by the gambling site, commonly at around £40 a transaction and a few hundred pounds a month, and that ceiling follows the phone number across every site accepting the method. Money cannot be paid back to a phone bill either, so a separate withdrawal option is always needed.
What the Cashier Has to Put in Front of You
The rules cover presentation as well as arithmetic, which gives you a short checklist for judging any licensed online casino:
• A direct link to the limit settings from the homepage and from deposit screens, reachable in as few clicks as possible
• A free text box for typing your own figure rather than a menu of preset amounts
• Limit setting presented as the default choice, with a deliberate step required to decline it
• A prompt at least every six months to review your account and transaction history, with the option of more frequent reminders
• A yearly nudge for customers who have never set anything
None of this is optional, and the reform was driven by research showing that players found the old arrangements confusing rather than by any complaint about the tools themselves.
What a Deposit Limit Does Not Do
The reformed control is precise about its job, which also means it leaves several things untouched:
• It does not assess whether the figure you chose is affordable for you
• It does not cap losses, because winnings can be staked again without a new payment
• It does not follow you to another operator or to a second account
• It does not hand back room when you withdraw
Read that list as the point rather than as a weakness. One clearly defined number, counted the same way everywhere, is easier to set honestly than a control whose maths shifted depending on where you happened to be playing.
