UK’s Best Siru Mobile Casinos 2026

Both sites accept the same payment method, so the differences are elsewhere. The table sets out what each operator is actually better at, along with the strength of the evidence we hold that it takes Siru.

That last column matters more than it looks. Mr Vegas answers a Siru-specific question in its help centre, which is about as direct as operator confirmation gets short of opening the cashier. Videoslots lists Siru on its payment page, but its description of the method is written for Finland, Norway and Sweden and quotes no sterling figure at all, even though GBP is a selectable account currency on the same page. We report that as we found it rather than converting the euro figures into pounds, which is what most comparison pages do.

Siru’s appeal is that it removes the bank from the transaction entirely. Its drawbacks are the mirror image of that convenience, since a charge on a phone bill is money committed before it is paid, and the cost of the service is not published as a rate.

The strongest argument for Siru is access. If you would rather not hand card details to a gaming site, or you do not have a card to hand, a phone number is enough to complete a deposit. Siru publishes no way to lift the £500 rolling limit, so for anyone who wants a spending ceiling it doubles as one.

The strongest argument against it is the fee. Siru states that its charge depends on what is being bought and that it is shown to you before you confirm, which means there is no rate you can check in advance.^[1] Comparison pages that quote a flat figure are not drawing it from Siru. If withdrawals matter to you, an e-wallet or an open-banking method handles money in both directions, and the fast withdrawal casino sites guide covers payout speed properly.

Paying by phone bill deserves more care than paying by card, for one specific reason. The money leaves your account weeks after you gamble it, on a bill that arrives at the end of the cycle, so the usual feedback of watching a balance drop is missing. Siru and your network both provide ceilings, and the casinos provide their own tools on top.

• The £500 Rolling Limit

  Siru applies a limit of £500 per 30 days to UK numbers, and it counts transaction fees towards that total rather than measuring the deposit alone.^[1] It is rolling, not calendar based, so it does not reset on the first of the month.

• Your Subscription Limit

  Your mobile plan may allow less for phone-bill purchases than Siru’s own figure. Siru says the most common UK subscription limit is £240 per month, and its terms state a general figure of €300 per month for the same type of limit.^[1][2] Whichever is lower is the one that will stop your payment.

• MySiru

  Siru’s self-service portal shows the payments made against your number and the limits currently applied to it. Check it before a deposit rather than after a decline.

• Ask Your Network to Bar Charges

  UK networks let you block or restrict third-party charges to your bill. If you would rather phone-bill gambling were not possible on your number at all, that bar is a firmer control than any casino setting.

• Casino Tools and GAMSTOP

  Set a deposit limit or take a time-out at the operator, or register with GAMSTOP to self-exclude from every UKGC-licensed site at once. Note that GAMSTOP covers gambling accounts, not payment methods, so it does not switch Siru off.

Free and confidential support is available from GamCare on 0808 8020 133, and from GambleAware. If a phone-bill charge has caused a problem you did not expect, raise it with your network’s billing team and with Siru’s own support.

This table only carries figures the operators or Siru actually publish. Where a value is not published, it says so, because an invented minimum is worse than an absent one when you are about to move money.

Neither casino publishes a Siru-specific minimum for UK players. Videoslots does publish figures, but only in euros and Nordic currencies, scoped to Finland, Norway and Sweden, so they are not UK limits and we will not present them as such. In practice the binding constraint is Siru’s own £500 per 30 days rather than anything either operator sets.

Because Siru is deposit only, your withdrawal will go out by a different method, usually the debit card or e-wallet you add afterwards. If a low minimum is what you are looking for, the £5 deposit casino sites and £10 deposit casino sites guides rank operators on exactly that, though you will be funding those accounts with a card or an e-wallet rather than with Siru.

This is the part of Siru most comparison pages get wrong, so it is worth being precise. Siru does not publish a fee rate. Not a percentage, not a flat amount, nowhere on its site. Its FAQ states that the transaction fee depends on what is being purchased and that it is always shown before you confirm the payment.^[1] Its terms describe the total charge as the price of the product, the telephone operator’s commission and the cost of the service.^[2]

A note on that £240. Siru’s FAQ gives it as the most common UK subscription limit, while its terms state €300 per month for the same category of limit, and we could not reconcile the two into a single figure.^[1][2] Treat £240 as a likely ceiling set by your network, not a guaranteed one, and check MySiru for the number that actually applies to you.

The practical consequence of an undisclosed rate is simple. You cannot budget a Siru deposit precisely before you start it, so read the total on the confirmation screen every time, particularly as that total is what counts against your £500 limit.

This is the complete list, and it is short on purpose. These are the only UK-licensed operators where we can evidence Siru support from the operator’s own published pages rather than from another comparison site.

You will find longer lists elsewhere. When we checked the brands named on them, the claims traced back to other affiliate pages rather than to the casinos, and several of those operators no longer show Siru in their own documentation at all. We would rather publish two we can evidence than ten we cannot.

If that list is too short to be useful, the full list of UK online casinos and the top 20 UK casino sites are the better places to choose from, and you can filter on the payment methods you actually want.

Every limit and fee statement on this page is taken from one of the following. Where two of them disagree, we have said so in the text rather than picking a number.
