Remote gambling operators serving Great Britain face a final compliance deadline on 30 September 2026. Revised Gambling Commission requirements will require clearly labelled gross deposit limits and stop further deposits when a customer reaches the chosen threshold.

This is no longer a consultation or proposal. The Gambling Commission published its consultation response on 7 October 2025, updated it on 22 May 2026 and confirmed 30 September 2026 as the effective date. The original 30 June deadline was extended after stakeholder feedback gave operators more time for technical development.

The key issue is not only what a customer sees on screen. It is whether the payment system enforces the same limit at the point of deposit.

What changes for operators

A gross deposit limit measures the total amount paid into an account during a defined period. Withdrawals do not reduce that total. From 30 September 2026, only this type of limit may be called a “deposit limit”.

  • Operators must offer gross deposit limits as a minimum.
  • The gross option must have at least equal prominence when other financial limits are available.
  • Available periods must include 24 hours, seven days and one month.
  • When a customer reaches the limit, the gambling system must block further deposits until the period restarts or a permitted increase takes effect.
  • Requests to increase a limit remain subject to a cooling-off period of at least 24 hours.

When customers set limits across more than one period, the most restrictive applicable limit must control. The Gambling Commission’s example shows how a daily limit can reduce the amount available under a weekly limit.

The difficult part is system behaviour

The headline change sounds simple. The implementation is not. Operators and gambling software suppliers must align account screens, payment flows, limit calculations, customer messages and cooling-off controls.

The system must also distinguish gross deposit limits from other financial tools. Operators may continue to offer net deposit, loss or stake limits, but those products cannot be presented as ordinary deposit limits.

A net deposit limit subtracts withdrawals. A loss limit is based on stakes minus winnings or returns. The distinction matters because each tool measures a different financial risk.

A customer who has reached a gross limit should not be able to add more funds simply because they have withdrawn money, switched gambling products or moved between linked screens. The Gambling Commission’s requirements place responsibility on the gambling system to prevent the further deposit.

What customers should see

For players, the practical test is clarity. An account should show what the limit measures, when it resets and what happens after it is reached.

GamRight, an independent safer-gambling publisher, warns that financial limits can help control spending. They do not make gambling risk-free or turn a limit into a spending target.

Operators must make the gross option available to new customers from the effective date. Existing customers must also receive access to the revised limit arrangements, including at the relevant prompted review points required under the technical standards.

Great Britain is not the whole UK

The new RTS 12B requirements apply to remote gambling regulated by the Gambling Commission in Great Britain: England, Scotland and Wales.

Northern Ireland has separate gambling arrangements, and the Gambling Commission does not regulate gambling activity there. The Channel Islands and the Isle of Man also operate under their own legal and licensing frameworks.

That makes jurisdiction a live compliance issue for operators serving more than one market. A company may hold a Gambling Commission licence for British customers while facing different requirements elsewhere.

Why the deadline matters

The 30 September 2026 deadline will test more than the wording on an account page. It will test whether operators apply one calculation consistently across deposits, withdrawals, payment providers, customer accounts and time periods.

For the Gambling Commission, the policy goal is a common and understandable financial-limit tool. For operators, the immediate risk is a mismatch between what the customer sees and what the payment system permits.

After the deadline, that gap becomes a regulatory problem rather than a design flaw. The change will be visible to customers at the point where a deposit succeeds or fails, but the hardest work will happen behind the screen.
