Top 10 UK Pay by Phone (Boku) Casinos, June 2026
Every operator in this ranking holds a UK Gambling Commission licence and accepts Pay by Phone (Boku) for deposits. We've signed up, deposited and withdrawn from each one in the last 60 days.

How Pay by Phone works at UK casinos
Pay by Phone is powered by Boku, an FCA-regulated payment provider. You enter your UK mobile number at the casino cashier, confirm a one-time SMS, and the deposit is added to your next monthly phone bill, or deducted from your pay-as-you-go credit.
Every UK mobile network supports it: EE, Vodafone, O2, Three, Sky Mobile, BT Mobile, Tesco Mobile, Virgin Mobile, GiffGaff, Lebara, Lyca, iD Mobile and more.
Daily £30 cap
Boku enforces a £30 daily deposit cap across all UK casinos combined. This is a hard, network-level limit, a deliberate responsible-gambling design choice and one of the reasons regulators are comfortable with the method.
- Hard £30 daily cap across all UK casinos
- No card, no bank details, no app
- Works on every major UK mobile network
- Withdrawals must use a different method (Trustly, card)
Why UK players love Pay by Phone
It's the fastest possible way to top up, under 30 seconds from cashier to gameplay, and the £30 cap means you literally can't overspend in a session. Perfect for casual play.
How the UK Gambling Commission protects players
Every casino we recommend for Pay by Phone (Boku) holds a remote licence from the UK Gambling Commission (UKGC). The UKGC enforces some of the strictest consumer-protection rules in the world: segregated player funds, mandatory affordability checks for higher spenders, age and identity verification at sign-up, and an outright ban on credit-card gambling since 14 April 2020.
That regulatory backdrop is the single biggest reason a UK Pay by Phone (Boku) casino is safer than an unlicensed offshore alternative, your deposit sits in a ring-fenced account, your withdrawals are legally enforceable, and any dispute can be escalated to a UKGC-approved Alternative Dispute Resolution (ADR) provider such as IBAS.
- All operators on this page hold a UKGC remote licence
- Player funds are segregated under licence condition 4.2
- Disputes can be escalated to IBAS, eCOGRA or ProMediate (ADR)
- Single Customer View deduplicates self-exclusion across UKGC operators
Pay by Phone (Boku) fees, limits and processing times at a glance
Across the UK casinos in our top 10, Pay by Phone (Boku) deposits clear at the same speed and with the same fee structure, UKGC operators are required to disclose any payment fee in their cashier and almost universally absorb the cost on GBP transactions.
Withdrawal speeds depend on the casino's internal review window first (typically 0–24 hours, faster for verified accounts) and the rail second. The fastest combined cash-out we measured during our 60-day test cycle was under three hours; the slowest, 4 working days for a first-time bank-transfer withdrawal pending document checks.
- Minimum deposit usually £10 (some Pay-by-Phone brands accept £3)
- Maximum deposit subject to your account's affordability tier
- Casino-side review: 0–24h for verified accounts
- All UK operators must confirm KYC before paying out
- Withdrawals are returned to the original deposit method where possible (UKGC source-of-funds rule)
Security: how UK casinos protect your payment data
Every UKGC-licensed operator must encrypt payment data in transit using TLS 1.2 or higher, store cardholder data in PCI-DSS-compliant environments, and run continuous fraud-monitoring on deposits and withdrawals. Pay by Phone (Boku) transactions on this page are all routed through PCI-DSS Level 1 acquirers.
On top of that, two-factor authentication is now standard at all major UK casinos, usually via SMS or an authenticator app, and any large or unusual withdrawal triggers an additional manual review under the casino's source-of-funds policy.
Responsible gambling tools you can use on every UK casino
UK licensees are required to offer a full suite of responsible-gambling tools regardless of which payment method you use. You can set deposit limits, loss limits, session-time reminders, reality checks and self-exclusion durations from one day up to permanent, all from your account settings.

When Pay by Phone (Boku) isn't the right choice
Pay by Phone (Boku) is excellent for the use case it's built for, but it isn't always the most efficient option. If you need very high per-transaction limits, a regulated bank-transfer route (Faster Payments / Trustly Pay-by-Bank) usually beats it. If you want the fastest possible withdrawal, a verified PayPal or Skrill account typically pays out in under three hours. And if you want zero exposure of your bank details, a Paysafecard voucher or a Pay-by-Phone deposit removes the link entirely.
