Gross deposit limit vs net deposit limit: UK gambling rules
From 30 September 2026 only a gross limit may be called a 'deposit limit' in UK online gambling. RTS 12B wording and the Commission's worked example.
A gross deposit limit caps the total a customer pays into a gambling account over a period, regardless of withdrawals. A net deposit limit adds withdrawals back, so taking money out re-opens headroom. From 30 September 2026, UK online operators must offer gross limits and may call only gross limits ‘deposit limits’, per Gambling Commission RTS 12B.
That is the whole of the gross deposit limit vs net deposit limit question for UK gambling, and the rest of this piece is the paperwork behind it: the date, which moved once; the operative wording, which was softened once; and the Commission’s own worked example, which shows why the distinction is worth a technical standard at all.
Why the date is 30 September 2026, not 30 June
The Commission’s implementation-extension notice, dated 26 May 2026, records that the first phase of improvements to consumer-management tools was introduced into the Remote Technical Standards in October 2025, with the second phase due on 30 June 2026. Following stakeholder feedback, the regulator extended the second-phase implementation period to the end of September 2026 “to allow for further operator technical development time”.
This desk read that notice, the Commission’s RTS upcoming-changes page and its deposit-limit research page on 11 September 2026. All three still give 30 September 2026 as the effective date; nothing on those three pages suggested a further slip.
Two housekeeping items from the same notice. First, the consultation response document was updated to clarify that from 30 September 2026 only gross deposit limits must be offered over fixed time frames; rolling and fixed time frames can both be used for other limit types. Second, an annex published alongside the consultation response on 7 October 2025 “contained small errors” and was temporarily withdrawn; the Commission says any downloaded or offline copy saved before 22 May 2026 should be disregarded.
Gross deposit limit vs net deposit limit: the Commission’s definitions
The cleanest definitions come from the regulator’s own research, Exploring consumer journeys using deposit limits, last updated 12 May 2025, which handed respondents a formula and a scenario. Applying the two formulae to the Commission’s scenario gives the following.
| Net deposit limit | Gross deposit limit | |
|---|---|---|
| Commission’s definition | The overall deposit limit remaining after any amounts have been added or removed from the gross total | The overall deposit limit before any amounts have been added or removed |
| Commission’s formula | Total Limit − Amount Deposited + Amount Withdrawn = Net Limit | Total Limit − Amount Deposited = Gross Limit |
| Scenario: £200 monthly limit, £100 deposited on day 1, £50 withdrawn on day 14 | £200 − £100 + £50 = £150 left to deposit | £200 − £100 = £100 left to deposit |
| Label permitted from 30 September 2026 | Not “deposit limit” | “Deposit limit” (mandatory description) |
The arithmetic in the third row is ours, using the Commission’s formulae; the research page poses the scenario as a question rather than printing the answer. The point it makes is simple: under a net limit, Jane’s withdrawal on day 14 buys her £50 of fresh deposit room, and under a gross limit it buys her nothing.
The research also measured whether customers could do that sum. In the net group, 458 respondents, 44 percent entered an incorrect amount and 43 percent a correct one, with 13 percent answering “do not know”. In the gross group, also 458, 46 percent answered correctly, 39 percent incorrectly and 16 percent did not know. The Commission’s own description is that comprehension of net limits was “poor” and comprehension of gross limits “comparable”. Neither figure is a majority. What the labelling rule fixes is not customers’ arithmetic but the fact that, until now, the same two words could mean either calculation.
What RTS 12B requires from 30 September 2026
The RTS upcoming-changes page states that all changes arising from the March 2025 supplementary consultation relate to RTS 12B, financial limits. Taking the page’s wording in order:
- Only limits that meet the definition of a gross deposit limit can be referred to as a deposit limit, and limits meeting that definition must be described to the customer as a deposit limit.
- The gambling system must prevent further deposits once a deposit limit is reached, until the defined period restarts or the customer takes action to increase the limit, subject to the standard 24-hour cooling-off period.
- As a minimum, the gambling system must offer gross deposit limits, defined as limiting the amount a customer deposits over a particular duration. The consultation draft said “as a default”; the final text says “as a minimum”, and the Commission explains that the change allows operators to continue to offer other forms of limits.
- Where more than one type of limit is offered, gross deposit limits must have at least equal prominence to the other types.
- Where a customer sets simultaneous time frames, a daily and a weekly limit for example, the most restrictive must always apply.
Read together, the standard does not ban net limits. It reserves a name. An operator may keep a net-style tool on the page, provided a gross tool sits beside it at equal prominence, and provided the net tool is not called a deposit limit. The notice’s phrase that operators must “in some cases re-introduce” gross limits reads as the regulator’s acknowledgment that some had dropped them; the notice does not name any operator.
What this desk could not check
The natural next step, tabulating what named operators currently call their limit tools and whether they net withdrawals, is not in this piece. In preparing it, this desk attempted to read four operators’ responsible-gambling help pages by automated fetch and read none of them: two refused the request, one returned a not-found page, and one redirected to a help-centre home page. We make no claim about any individual operator’s current labelling, and none should be inferred.
This sits alongside the Commission’s other tool-side work. The financial risk assessments thresholds are expressed in net deposits over rolling windows, which is a different instrument with a different purpose, and the confusion between the two vocabularies is one more reason the labelling rule earns its keep. Our mid-2026 scorecard tracks the wider set of white-paper deliverables; this item’s date has moved once since, and this piece is the correction. On the infrastructure side, GamStop remains the blunt instrument and the deposit limit the fine one.
Questions readers ask
What is a gross deposit limit?
Per the Commission’s research wording, a gross deposit limit is the overall deposit limit before any amounts have been added or removed, with the formula total limit minus amount deposited. The RTS 12B wording effective 30 September 2026 describes it as a limit on the amount a customer deposits into their account over a particular duration. Withdrawals do not restore any of it.
What is the difference between a net deposit limit and a deposit limit?
From 30 September 2026 the label ‘deposit limit’ is reserved, under RTS 12B, for limits that meet the gross definition. A net deposit limit is calculated as total limit minus deposits plus withdrawals, so a withdrawal increases the remaining allowance. A gross limit ignores withdrawals. Operators may still offer net-style limits, but must not describe them to customers as deposit limits.
When do the new UK deposit limit rules come into force?
The revised RTS 12B requirements take effect on 30 September 2026. They were originally due on 30 June 2026, but the Commission’s notice of 26 May 2026 extended the implementation period to the end of September, citing stakeholder feedback and operator technical development time. The first phase of the tool improvements was introduced in October 2025. As of this writing, the September date stands.
Can UK operators still offer net deposit limits?
Yes, on the wording the Commission has published. The final RTS 12B text says the system must offer gross deposit limits ‘as a minimum’, softened from ‘as a default’ after consultation, and the Commission says this allows operators to continue offering other forms of limit. The conditions are that gross limits get at least equal prominence and that only gross limits carry the name ‘deposit limit’.
Do deposit limits include withdrawals?
It depends on the type, which is the whole problem the Commission set out to fix. A net limit nets withdrawals off, so money taken out restores headroom. A gross limit does not. From 30 September 2026 anything labelled a deposit limit must be gross, so a withdrawal will not restore any of it. Until then, the label is not tied to a single calculation, which is what the Commission’s March 2025 consultation set out to clarify.
