Two accounts, the same £200 monthly ceiling on the screen, and a different amount of money moving through them. On one, £200 deposited is £200 in and the cashier stops there. On the other, a £150 withdrawal part-way through the month hands £150 of headroom back, and £350 goes in across the period without the displayed number ever moving. Same label, different arithmetic.

From 30 September 2026, only one of those may carry the plain name. The Gambling Commission’s published record of upcoming changes to the Remote Technical Standards states that “only limits that meet the definition of a ‘gross’ deposit limit can be referred to as a deposit limit”, and that the gambling system “must prevent a customer from further depositing funds once a deposit limit is reached”. Gross limits must be offered as a minimum, and where an operator runs more than one type, gross limits are to be shown “with at least equal prominence to other limit types”.

The other version does not disappear. It gets a name. The accompanying implementation guidance defines a net deposit limit as “the amount deposited into the account minus any withdrawals made for the period or duration of the limit applied”.

Which is why this lands on a payouts desk. Inside the financial-limits standard, that definition is the one place where a withdrawal changes what a customer is allowed to put in. Read from the cashier rather than from the rulebook, a payout under a net limit is two things at once: money leaving, and headroom returning. The faster the rail, the faster the headroom. A desk that spends its week counting hours between request and credit has an obvious interest in a rule that makes that credit do a second job.

The rest of the package is housekeeping with consequences. The guidance retires “spend limits” in favour of “stake limits”, and where a customer sets simultaneous timeframes, “the most restrictive must always apply”.

The date has already moved once. The same page records the implementation date changing from 30 June 2026 to 30 September 2026, in an update dated 22 May 2026. Operators have had the runway. Customers get a little over five weeks’ notice that a phrase on their account settings page may be about to mean something narrower than it did.

What none of it does is shorten a payout. The current RTS 12 financial limits requirement governs limit-setting facilities, not processing windows; nothing in the package reaches the hours between request and credit. We made the point when covering commercial recurring payments that some payments stories are deposit stories. This is another one — with the unusual feature that the payout side is written into the definition.

18+. If the wording on your own limits page changes this autumn, read it before assuming the ceiling is still the one you set. GambleAware is at begambleaware.org.
