Deposit limit rules for UK casinos

Deposit limit rules for UK casinos at a glance

A deposit limit is a ceiling you choose on how much money you can pay into a casino account over a set period. In Great Britain, the Gambling Commission does not set the amount for you. It sets the rules for how operators must offer, apply and change the limits you pick. Those rules live in two places: the Commission’s licence conditions and codes of practice and its Remote Technical Standards, specifically RTS 12 on financial limits.

Two waves of change have reshaped them. From 31 October 2025, operators had to prompt new customers to set a limit before their first deposit and make limits easier to find. Then, by 30 September 2026 (a deadline extended from 30 June 2026), they had to offer a genuine gross deposit limit and stop using that name for anything else. As of 20 October 2026, both sets of changes are in force.

The limit prompt before your first deposit

Open a new account at a UK-licensed casino today and, before any money goes in, you should see a screen asking you to set a financial limit. The Commission’s rules, explained in its blog on changes to customer-led financial limits (opens in a new tab), require that:

• Setting a limit is the default choice, not an optional extra.
• If you decide not to set one, you must actively confirm that.
• You type the amount yourself; pre-filled or greyed-out suggested amounts are not allowed.
• Limits apply at account level, across everything you play with that operator.
• A clearly visible link to limit settings sits on the homepage and the deposit pages, reachable in as few clicks as possible.

Operators may set a minimum amount for a limit, for example for payment processing reasons, and may require whole pounds to reduce typing mistakes. They may not use those rules to nudge you towards a particular figure.

Gross vs net: what counts as a deposit limit now

Before these rules, some sites offered “deposit limits” that actually subtracted your withdrawals, which could let you pay in far more than the figure you set. RTS 12 now defines a deposit limit as a gross limit: it caps what you deposit over the period, full stop. Net limits can still exist alongside it, but they must be called something else.

The difference grows with every withdrawal. A gross limit tells you exactly how much new money can go in; a net limit tells you how much you can be down. Both have uses, which is why our safer gambling tools comparison sets them side by side with a loss limit.

Gross deposit limits must use a fixed time frame, and the operator must tell you clearly when the period resets. A rolling window that restarts whenever you return after a break is not allowed for customer-set limits.

Raising and lowering a limit: the cooling-off rule

RTS 12 treats the two directions very differently, on purpose. Lowering a limit is a protective decision, so it happens straight away unless a technical failure prevents it, in which case you should be told when it will apply. Raising a limit is the risky direction, so it only happens at your request, after a cooling-off period of at least 24 hours, and only once you take positive action at the end of that period to confirm it.

Worked example: moving from £50 to £200 a week

1. Monday 8pm: you ask to raise your weekly deposit limit from £50 to £200. The £50 limit stays in force.
2. Tuesday 8pm: the 24-hour minimum has passed. Nothing changes automatically.
3. Wednesday morning: you log in and the site asks you to confirm the new £200 limit. Only after you confirm does it apply.
4. If you decide against it, you simply do not confirm, and the £50 limit carries on.

Some operators use longer waits than 24 hours; the rule sets a minimum, not a maximum. Our answers on whether you can change a deposit limit and why increases take time go into the practical details.

Limit periods and review reminders UK casinos must give

Every UK operator must offer limits covering at least these periods, and it must send review prompts on a set schedule.

You can ask for more frequent reminders. These sit alongside reality checks, which remind you how long you have been playing during a session.

How to set a deposit limit at a UK casino

1. Log in and look for the limits link on the homepage or deposit page, which the rules say must be clearly visible.
2. Choose “deposit limit” (the gross type) rather than a net or loss limit, unless you want both.
3. Pick the period: daily, weekly or monthly.
4. Type an amount you would be comfortable losing in full, based on your gambling budget.
5. Save it and note the date and time the period resets.
6. Set a calendar reminder to review it; lower it immediately if it ever feels too high.

Who the deposit limit rules apply to

The rules bind every business holding a Gambling Commission remote licence when it serves customers in Great Britain: casino, betting and bingo sites alike. They also apply to existing customers, though you are not moved automatically. If you already have a net or loss limit, you can keep it while the operator still offers it, and switch to a gross deposit limit whenever you wish.

They do not reach unlicensed offshore sites, which ignore British rules altogether, and Northern Ireland is outside the Gambling Act 2005. Our page on Northern Ireland gambling law explains that gap.

What a deposit limit does not do

• It does not cap the amount you stake: winnings already in your balance can still be played.
• It works at one operator only. A limit at one site has no effect at another, so it is not a substitute for self-exclusion.
• It is not the same as the operator’s own maximum deposit per transaction, which is a business setting.
• It does not remove the operator’s duty to interact with you if your play shows signs of harm; see customer interaction rules.

Why the Commission changed the deposit limit rules

Announcing the changes on 7 October 2025, the Commission said in its news article on the new deposit limit rules (opens in a new tab) that its aim was to give consumers greater awareness and control over their gambling. Two problems sat behind that: limits were often hard to find, and the term “deposit limit” meant different things on different sites. Making the limit screen the default, and fixing what the name means, tackles both.

If a limit was not applied, and where to get help

If an operator let you deposit beyond a limit you set, or delayed a reduction without good reason, raise a complaint with it in writing, then take it to an approved ADR body if needed. Our guide on how to complain about a casino covers the steps.
