Online casino players in Britain are now seeing a change in how deposit limits work, following a rule that took effect on 30 September 2026. Under updated standards from the Gambling Commission, every licensed online operator must offer a gross deposit limit as a standard option, and it must be labelled simply as a “deposit limit”. The change looks technical on the surface, but it affects a tool that millions of players use to keep their spending under control, so it is worth understanding what has actually changed and why.

What the new deposit limits rules change

The requirement sits within the Commission’s remote gambling and software technical standards, known as the RTS. The relevant section, RTS 12B, was rolled out in two phases. The first set of improvements arrived in October 2025. The second phase was originally due in June 2026 but was pushed back to 30 September 2026 to give operators more time to build it.

From that date, three things apply to every online casino and betting site holding a British licence. Operators must offer a gross deposit limit, including bringing it back where it had previously been removed. That limit must be called a “deposit limit” and no other limit type may use that name. And it must be shown with at least equal prominence to other financial limits, rather than tucked away beneath them.

Gross versus net, and why the wording matters

The distinction between a gross and a net deposit limit sounds like jargon, but it changes how much you can actually spend. The Commission defines a gross deposit limit as a cap on the amount a customer deposits over a set period. A net deposit limit, by contrast, is the amount deposited minus any withdrawals made during that period.

The practical effect is real. With a net limit, money you withdraw frees up room to deposit again. If you set a limit of £100 for the week, deposited the full amount, then withdrew £30, you could put another £30 back in and still sit inside the limit. A gross limit does not work that way. Once you have deposited £100, that is the cap for the period, whatever you take out. For a player trying to hold a firm line on spending, the gross version is the stricter and clearer of the two.

Why this matters for players

Deposit limits are one of the most widely used safer gambling tools, and their value depends on them being easy to find and hard to misunderstand. The previous mix of gross and net limits, and the inconsistent labelling across sites, made it easy for a player to think they had capped their spending when the limit was actually looser than it looked. Standardising on a gross limit, under a single clear name, removes that ambiguity.

It also means the limit you set on one licensed casino should now behave the same way on another. That consistency matters when you are comparing operators or using more than one account. If you already have a limit in place, it is worth checking how your site now describes it, because the figure you set under the old system may behave differently under the new one.

What it means for bonuses, payments and safer play

The change is aimed at protection rather than promotions, but it touches both. Deposit-based bonuses, such as matched welcome offers, are calculated on what you put in, so a firm gross limit naturally caps how much you can chase a bonus in a given period. Players who rely on deposit limits as a budgeting tool will find that the cap now holds regardless of withdrawal activity, which makes it a more reliable guard against topping up again after a win has been cashed out.

None of this replaces the other controls on offer, including time-outs, self-exclusion through GAMSTOP, and reality checks. Deposit limits are one layer. Used alongside the others, they give players a practical way to decide in advance how much is enough, before money and emotion are in play.

What players should watch next

The Commission has signalled that player protection remains a priority, with further work on how operators identify and respond to signs of harm. Separate rules on new gaming machines are also due, although those are aimed at land-based venues rather than online play. For online players at UK casinos, the near-term point is simpler. Expect the deposit limit option to be presented more prominently at sign up and in account settings, and expect the wording to be consistent from one licensed site to the next. If a site makes the tool hard to find, or uses confusing labels, that is now a compliance failing rather than a design choice.

Betspin view

We see this as a sensible, low-drama change that does what good regulation should do, which is make a useful tool work the way players expect. The gross limit is the stricter option, and defaulting to it closes a gap that many players never knew existed. Our one note of caution is that a limit is only as good as the decision to set one. The rule makes the tool clearer and more prominent, but it is still up to each player to use it. If you play at licensed casinos, take a moment to set or review your deposit limit while the change is fresh, and read our wider guidance on responsible gambling if you want to understand the full set of tools available.
