Boku casinos UK: complete list of UKGC casinos accepting Boku deposits in 2026

By Jack Carter, Editor, paybyphonecasino.co.uk. Every operator is checked against the UKGC public register; last check 29 May 2026.

A Boku casino is a UKGC-licensed online casino that accepts deposits charged to a UK mobile bill through the Boku group. The FCA-authorised Electronic Money Institution behind the rail is Boku Account Services UK Limited (FRN 900030); Boku Network Services UK Limited (Companies House 05044979) is the related trading entity. Boku is one of the carrier-billing rails behind the UK's direct carrier billing market, and every operator using it must hold a remote casino licence from the UK Gambling Commission. Deposits are capped at £8 on first use, £30 per day, and £240 per calendar month per consumer. Withdrawals don't route back to a phone bill.

Here's the 2026 reality, stated plainly. Casushi is the one UKGC-licensed operator still confirmed to accept Boku, and several brands that once did, Sky Vegas, Virgin Games, and Foxy Bingo, have dropped it. This page covers the £8 first, £30 daily, and £240 monthly Boku caps, the EE, O2, Vodafone, and Three carrier matrix, the Boku versus Fonix distinction (MrQ and Hot Streak Casino now run on Fonix), and an honest account of why the Boku operator pool has shrunk.

What is a Boku casino

A Boku casino is a UKGC-licensed online casino that accepts deposits charged to a UK mobile bill via the Boku group, billed to a mobile contract or pay-as-you-go balance rather than a card. The casino never sees your card or bank details, because the charge travels through Boku and lands on your mobile account. Boku is one of two carrier-billing rails behind the UK's pay by mobile casino UK 2026 (full comparison), and Fonix Mobile is the other.

The corporate structure matters here, because two UK entities share the Boku name. The parent is Boku, Inc., founded in 2008 and headquartered in San Francisco. In the UK, Boku Network Services UK Limited is the trading and integration entity, registered at Companies House under 05044979. But the separately-registered Boku Account Services UK Limited is the regulated arm, so any regulatory claim points to Account Services, not Network Services.

Boku Account Services UK Limited is authorised by the Financial Conduct Authority as an Electronic Money Institution under FRN 900030. That authorisation runs under the Electronic Money Regulations 2011 and the Payment Services Regulations 2017, which means Boku is regulated as an electronic money institution, not as a bank and not as a gambling operator. So when a casino lists Boku at the cashier, the rail behind it is an FCA-authorised payment firm, and the casino itself is separately licensed by the UK Gambling Commission. Casushi is the UKGC-licensed operator still confirmed to accept Boku in 2026, covered in full below.

For the record, Boku has never been owned by PayPal. Boku, Inc. traded on Nasdaq before being taken private by investors in 2024, and PayPal has no stake in it.

Best Boku casinos UK 2026

Casushi is the one UKGC-licensed casino confirmed to still accept Boku in 2026. We list a single operator here on purpose, and the reason is method, not laziness.

We build this list one way. First, we confirm the licensee and account number on the UK Gambling Commission public register. Then we check that the operator demonstrably takes a Boku deposit today, at the live cashier or through a current public-source listing. Where competitors still list five to ten "Boku casinos", this page lists the one that's currently true and is honest about the rest. And if you want to compare the providers sitting behind these casinos, see our Boku vs Fonix vs Siru compared guide.

Casushi (Boku): the one confirmed operator

Casushi is the only operator in our pool with confirmed-current Boku support, which makes it the lead pick for anyone who specifically wants carrier billing. It's operated by Solaya Group Limited under UKGC account number 100050, a detail you can verify both on the register and in the casino's own banking page. The minimum Boku deposit is £10, and Casushi credits the deposit instantly while the charge lands on your next mobile bill.

The welcome offer, per aggregator consensus in May 2026, is 100% up to £50 plus 50 spins on Starburst. Treat that as indicative until you confirm it at signup, and read the bonus terms, because some operators exclude phone-funded deposits from the welcome offer. Casushi is Sky Mobile compatible too, since Sky Mobile runs on the O2 network. And remember the Boku £8 first-deposit ceiling here: your first carrier-billed top-up is limited to £8 before the standard £30 daily allowance applies, which is a Boku rule rather than a Casushi one.

How Boku payments work at UK casinos

A Boku-billed UK casino deposit is capped at £8 on first use, £30 per day, and £240 per calendar month per consumer. The deposit itself takes five steps, and the whole flow runs through your phone, not a card.

To deposit, open the casino cashier and select pay-by-mobile or Boku. Enter your UK mobile number. Confirm the SMS PIN the provider sends. The deposit appears in your casino balance instantly. The charge then lands on your next mobile bill if you're on contract, or comes off your pay-as-you-go credit. One caveat on the word "instant": the casino credit is instant, but the bill charge is end-of-month for contract customers.

The £8 first-deposit ceiling applies at most UK casinos to a new payer-merchant pair. And Boku's risk policy caps your first carrier-billed transaction at that merchant at £8, so once it settles, your allowance there rises to the standard daily and monthly limits. It's a one-time gate, not a recurring cap.

The £30 daily cap is the figure most people search for, and it's per consumer, not per casino. The £240 monthly cap works the same way, applied per consumer across a calendar month. Both are Boku-specific. So don't confuse them with the £40 daily ceiling you'll see quoted for Fonix and Siru, which sits under separate Phone-paid Services Authority rules.

Here's the part competitors miss. The £30 daily cap is set at the carrier-PSP layer and applies in aggregate across every Boku-billed gambling merchant. Opening a second pay-by-phone account doesn't unlock a second £30 allowance. Deposit £20 at one Boku casino, and you've £10 left across all of them that day. It's one consumer, one £30 daily allowance, every Boku merchant combined.

Read the right way, the £30 cap isn't a quirk of carrier billing. It's a built-in deposit ceiling that pre-dates the UKGC's 31 October 2025 deposit-limit prompt mandate by more than a decade, and the October 2025 rule effectively made it the market standard. So a Boku casino arrives with a responsible-gambling limit already wired into the rails. For the detail, see Boku's £30 cap as a built-in UKGC deposit limit.

Mobile networks supported by Boku

Boku gambling carrier billing works on all four UK mobile network operators, EE, O2, Vodafone, and Three, plus most major MVNOs. The full EE, O2, Vodafone and Three Boku compatibility matrix maps support by operator, but the headline is simple: the four main networks all clear a Boku casino deposit.

The major MVNOs ride on an MNO backbone, so carrier billing usually follows the host network. But some MVNOs block gambling carrier-billing in their own terms regardless, so it doesn't follow automatically. Here's where each one stands today.

Sky Mobile supports Boku gambling carrier billing, and it sits on the O2 network, where pay-by-phone casino deposits remain functional in May 2026. Sky Mobile changed its carrier-billing setup in early 2025, which left some older guides out of date, so the current status is worth stating plainly: it works. For the full picture, see the Sky Mobile pay-by-phone casino status page.

The SMS confirmation step is the carrier-side authorisation point. When you deposit, the network sends a one-time PIN to your handset, and the deposit only clears once you confirm it. If the SMS never arrives, the deposit won't go through, which usually points to a network or coverage issue rather than a casino one. Boku works for both contract and pay-as-you-go customers, though PAYG users need enough credit at the moment of deposit, because there's no overdraft on the method.

Boku vs Fonix vs Siru (and Payforit, legacy)

Boku, Fonix, and Siru Mobile are separate companies with separate confirmed UKGC-operator integrations. They aren't interchangeable, and the operator footprint is what tells them apart. Compare all three in our Boku vs Fonix vs Siru compared guide.

Boku is a US-incorporated group: Boku, Inc. sits above Boku Network Services UK Limited, the trading entity, and Boku Account Services UK Limited (FRN 900030), the FCA-authorised Electronic Money Institution. Fonix Mobile plc is UK-incorporated and listed on the London Stock Exchange under the ticker FNX, founded in 2006 and admitted to the exchange in October 2020. And Siru Mobile is a Finnish-origin niche carrier-billing provider that sits inside the same direct carrier billing category rather than standing as a separate anchor brand.

The confirmed 2026 operator-by-PSP map is short, and it's the only one we'll vouch for.

A note on those caps. Boku's daily ceiling is £30; the Fonix and Siru carrier-billing ceiling is £40 per day under Phone-paid Services Authority rules, both with a £240 monthly limit. Mr Vegas on Siru lists a headline £5.12, which is the roughly 25% Siru carrier-fee uplift on a £4 net deposit. And the brands that once took Boku, Sky Vegas, Virgin Games, and Foxy Bingo, have dropped it, so they belong in no PSP column here.

One piece of history clears up a lot of confusion. Payforit, the carrier-billing brand the UK networks ran collectively, closed to new merchants and effectively wound down by 2024. It was the legacy rails layer that Boku and Fonix now sit on top of. So in 2026, Boku, Fonix, and Siru Mobile are the live UK PSPs for casino carrier billing. To weigh the two main ones, see Fonix vs Boku for UK casino deposits.

Boku withdrawal limitations

No, you can't withdraw casino winnings to your phone bill, ever. Boku carrier billing is a one-way route, so UK casino withdrawals go to a registered debit card, bank account, or e-wallet instead.

The block is both regulatory and mechanical. The UK Gambling Commission's anti-money-laundering rules require withdrawals to go to a verified account in your name that supports source-of-funds checks, and a mobile carrier can't provide that. On top of that, the carrier itself has no mechanism to credit a bill, because the rails only run merchant to carrier to your bill, never the reverse. This is true of every carrier-billing PSP, not just Boku, so Fonix is identical.

So withdrawals route through a standard method. You'll typically choose a Faster Payments bank transfer, a debit card refund, or an e-wallet, depending on what the operator offers. The deposit method doesn't have to match the withdrawal method, but most UKGC operators require at least one verified non-Boku route on the account before they'll process a payout. At Casushi, that means adding a debit card or bank account before your first cash-out, so the route is ready when you need it. For the full walkthrough, see Boku deposit and withdrawal mechanics explained.

Why some UK casinos are dropping Boku in 2026

The April 2026 Remote Gaming Duty doubling, from 21% to 40%, has accelerated Boku removal at thin-margin operators. The duty applies to operator gross gaming yield, and Boku's processing fee compounds the hit on small carrier-billed deposits, where the deposit value relative to the fee is unfavourable.

And that cost pressure is industry-wide. A BetterGambling study in October 2025 projected that 800-plus UK operators could close by 2027 under cumulative cost pressure. Boku integrations are often the first cost to cut at thin-margin brands, because they serve a small share of total deposits but still need an active commercial integration to maintain.

You can see the contraction in the brands that have already gone. Sky Vegas, operated by Bonne Terre Limited, has removed Boku. So have Virgin Games, operated by Gamesys Operations Limited under Bally's, and Foxy Bingo, operated by LC International Limited under Entain. The In Touch Games licence surrender took mFortune, PocketWin, and Mr Spin out of the market on top of that.

So why does Casushi stay? Typically because the integration cost is amortised across a larger operator platform, which makes a niche payment method worth keeping where a standalone brand can't justify it. This list is current as of May 2026 and is reviewed quarterly, with the cadence shortening to monthly during the April to October 2026 duty-fallout window. The constraint is operator-side, not Boku-side, so there's no evidence Boku itself is leaving the UK.

Frequently asked questions

What casinos accept Boku?

As of 2026, Casushi is the UKGC-licensed casino confirmed to still accept Boku. Several brands that once did, Sky Vegas, Virgin Games, and Foxy Bingo, have dropped it. Casushi is operated by Solaya Group Limited under UKGC account 100050, verifiable on the public register.

Is Boku a safe payment method?

Yes. Boku Account Services UK Limited (FRN 900030) is FCA-authorised as an Electronic Money Institution under the Payment Services Regulations 2017 and the Electronic Money Regulations 2011. Any casino using Boku must also hold a UK Gambling Commission licence, so two regulators sit behind the deposit.

Which UK casinos still accept Boku?

As of 2026, Casushi is the one confirmed Boku-accepting UKGC operator, operated by Solaya Group Limited under account 100050. The list is reviewed quarterly, because the operator pool keeps contracting under cost pressure. Verify the licence on the public register before you deposit.

Why are casinos dropping Boku?

The April 2026 Remote Gaming Duty doubling, from 21% to 40%, has accelerated cost-cutting at thin-margin operators, and Boku integrations are often first to go. They serve a small share of deposits but require an active commercial integration to maintain.

How much can you deposit with Boku at a casino?

£8 on first use, £30 per day, and £240 per calendar month per consumer. These are Boku-specific carrier-PSP caps, not casino limits, and the £30 daily allowance applies across every Boku-billed gambling merchant combined.

Does PayPal own Boku?

No. Boku, Inc. traded on Nasdaq before being taken private by investors in 2024, and PayPal has never owned it. The FCA-authorised UK arm is Boku Account Services UK Limited (FRN 900030).

What is the £30 Boku limit?

It's Boku's per-consumer daily ceiling on UK gambling carrier-billed deposits. It applies in aggregate across every Boku-billed gambling merchant, so it's one consumer, one £30 daily allowance, every merchant combined, not a fresh £30 per casino.

Can you withdraw from a casino to Boku?

No. Carrier billing is a one-way route under UK Gambling Commission anti-money-laundering rules. Withdrawals route to a registered debit card, bank account, or e-wallet instead, and most operators require a verified non-Boku route before they'll pay out.

How does the Boku £8 first deposit work?

Boku's risk policy caps a new payer-merchant pair's first deposit at £8. After that first transaction settles, your allowance at that merchant rises to the standard £30 daily and £240 monthly limits. It's a one-time gate, not a recurring cap.

Which UK mobile networks support Boku?

All four UK MNOs, EE, O2, Vodafone, and Three, plus the O2-based MVNOs Tesco Mobile and Sky Mobile. Giffgaff and Lebara block gambling carrier-billing in their own terms, and Asda Mobile is conditional, so check the cashier recognises your network before depositing.

What is Boku Network Services UK Limited?

It's the UK trading and integration subsidiary of Boku, Inc., registered at Companies House under 05044979. The separately-registered Boku Account Services UK Limited (FRN 900030) is the FCA-authorised Electronic Money Institution that holds the regulated permissions.

Is Boku regulated by the FCA?

Yes. Boku Account Services UK Limited (FRN 900030) is authorised as an Electronic Money Institution under the Payment Services Regulations 2017 and the Electronic Money Regulations 2011. The trading entity, Boku Network Services UK Limited, is not the FCA-authorised arm.
