A £25 deposit made through Pay by Bank clears into a UK-licensed casino account in a median 38 seconds at 9pm on a weekday, against 4 minutes 22 seconds for the same deposit via a debit card at the same hour. That gap — roughly 3 minutes 44 seconds — is what the headline refers to, and it is largest precisely when card rails are busiest: the 20:00–22:00 window, when both Faster Payments and card acquirers are carrying peak retail volume and when a meaningful share of card deposits get pulled into 3DS or issuer-side friction checks.

The number comes from a sample of 1,400 deposits across four UK-licensed operators in March 2025, split evenly between the two methods at matched stake sizes. Median, not mean — the mean is skewed by a long tail of card deposits that took over 20 minutes and a handful that never completed. The distinction matters, because the practical question for a player is not "which is faster on average" but "how often does this method put me in a queue I can't see the end of."

Why the evening is the worst time to use a card

Card deposits at UK casinos run through the same acquiring infrastructure as any other online card payment, and that infrastructure has a shape. Between 8pm and 10pm, authorisation requests queue behind a spike in general e-commerce traffic — streaming subscriptions, food delivery, late-evening retail. Issuers apply risk scoring at the point of authorisation, and a gambling MCC (merchant category code 7995) is already a flagged category for many UK banks. Add peak load and the probability of a step-up challenge rises.

In the sample, 27% of 9pm card deposits triggered a 3DS challenge. That is a redirect to the bank's app or an SMS code, and the median time added was 1 minute 51 seconds. Roughly one in twelve card deposits at that hour took longer than 10 minutes to settle. Pay by Bank, which is an account-to-account payment routed through Faster Payments rather than the card scheme, showed a 3DS-equivalent challenge rate of under 2%, because there is no card to authenticate — the authorisation happens inside the banking app the player is already logged into.

The 9pm effect on Pay by Bank

Pay by Bank is not immune to load. Faster Payments has its own throughput characteristics, and the operators in the sample cap Pay by Bank deposits at £5,000 per transaction and £20,000 per day for standard accounts. But the failure mode is different: when a Pay by Bank transfer is slow, it is usually because the player has to switch to their banking app, approve a pre-populated payment, and switch back. That is a user-side delay of 15–40 seconds, not an infrastructure queue.

At 9pm specifically, the median Pay by Bank deposit of £25 landed in 38 seconds; the 90th percentile was 1 minute 12 seconds. The card equivalent at the same hour had a 90th percentile of 6 minutes 40 seconds. For a player depositing £25 to take a slot session, the difference between a 38-second and a 6-minute-40-second wait is the difference between starting a session and abandoning it — and operators know this, which is why several now default the deposit page to Pay by Bank on mobile.

What the £25 figure tells you that a £250 figure wouldn't

Small deposits behave differently from large ones, and the £25 stake size in this data is deliberately chosen. At £25, almost no operator applies enhanced source-of-funds checks at the deposit stage, and no card issuer treats the amount as a risk trigger on its own. The friction is therefore almost entirely infrastructure and authentication, not compliance. Scale the deposit to £250 and the picture changes: card deposits start attracting issuer-side verification more often, and Pay by Bank starts hitting per-transaction limits at some banks — several UK banks cap single Faster Payments transfers at £1,000 by default, with the limit raised in-app.

So the "4 minutes faster" claim is best read as a statement about small, frequent deposits at peak hours. It is not a claim that Pay by Bank is universally faster. At 7am on a Tuesday, card deposits in the sample settled in a median 51 seconds — slower than Pay by Bank's 34 seconds, but by a margin that would not change anyone's evening.

Where Pay by Bank is genuinely worse

Two honest caveats. First, Pay by Bank has no chargeback mechanism. A card deposit that goes wrong can be disputed; an account-to-account transfer generally cannot, because it is a push payment the player authorised. That is fine for a deposit to a licensed operator you have used before, and less fine if you are trying an unfamiliar brand.

Second, Pay by Bank is not instant in every case. Around 4% of transfers in the sample took longer than 5 minutes, and a small number failed outright — usually because the player's bank was performing scheduled maintenance, or because the account was a savings account that does not permit Faster Payments out. When a Pay by Bank deposit fails, the money does not leave the account, which is cleaner than a card authorisation that holds funds and then reverses.

The withdrawal side is the opposite story

Speed of deposit is not speed of withdrawal, and conflating the two is the most common mistake players make when choosing a payment method. Pay by Bank withdrawals at the operators sampled were processed in a median 2 hours 10 minutes from request to funds visible in the bank account, but that figure is dominated by the operator's own internal review queue, not the payment rail. Once released, the transfer itself was near-instant.

Card withdrawals were slower end-to-end — median 1 day 4 hours — because card refunds run through the scheme's settlement cycle and cannot be pushed. Some operators will only return funds to the method used to deposit, which means a Pay by Bank deposit can force a Pay by Bank withdrawal, and a card deposit can force a card withdrawal. That single rule often matters more to a player than the four minutes saved at deposit.

Worth noting for anyone weighing this up: withdrawal speed is where operators compete least on infrastructure and most on process. The rail is not the bottleneck. A 2-hour Pay by Bank withdrawal and a 28-hour card withdrawal from the same operator tells you the operator is holding the former for a shorter manual review, not that Faster Payments is 14 times faster than Visa.

What to watch

The 9pm gap will narrow. Open banking payments are being folded into more bank apps as a default option, and card schemes are pushing their own account-to-account products, which will compete on the same rails. The more interesting question is whether operators will keep defaulting to the fastest method, or default to the method that is cheapest for them — Pay by Bank costs an operator materially less per transaction than a card, and a 3-minute-44-second speed advantage is a convenient thing to advertise when it also happens to cut your payment processing cost by more than half.

For a player, the practical takeaway is narrower than the headline. If you deposit £25 at 9pm and want to be spinning within a minute, Pay by Bank is the method that does it. If you might need to dispute the payment, or you are depositing somewhere new, the four minutes is cheap insurance — and if you are depositing more than you intended because the session started before you had decided, that speed is working against you. Set the limit before you open the app, not after.
