Bank Gambling Blocks and the Transfer They Mostly Miss

By Priya Desai, Senior Writer, PaymentsLast checked 17 October 2026Checked by Gareth Owens

Bank Transfer

A gambling block in a banking app is a useful brake, and most pages about bank transfer casinos describe it as if it covered the method. The published descriptions say otherwise. At the banks whose pages we read, the block is a card control, keyed to the merchant category code of a card payment; one bank states outright that its block does not affect bank transfers at all.

This page lists the ten banks on the Gambling Commission's page about blocking gambling transactions, quotes what each bank's own page says the block is built on where we could read it, draws the line between a card payment and a transfer, and sets out the two tools that reach every payment method. It prints no claim about a bank whose page we did not read, and it does not describe any block as covering a transfer unless the bank says so.

The ten banks on the Commission's list

The Gambling Commission keeps a page for players who want to block gambling transactions, and the version updated in October names ten banks with a block in their apps: Bank of Scotland, Barclays, Halifax, HSBC, Lloyds, Monzo, NatWest, RBS, Santander and Starling. The page notes that Halifax pairs its block with the Gamban blocking software, that HSBC applies a cooling-off period before the block can be lifted, and that Monzo removes its block only through its support team.

The page describes the blocks as applying to a current account or a debit card. It does not say, for any bank, whether a Faster Payment to a gambling operator is caught, and that silence is why the bank-by-bank section below quotes the banks' own pages where we could read them and says nothing where we could not.

Card payment or transfer: the line the blocks are built on

A debit card payment to a casino is a transaction to a card merchant, and card merchants carry a merchant category code that identifies gambling. A block that acts on that code catches the payment. A bank transfer, whether typed manually or started through an Open Banking provider, is a Faster Payment from your account to the operator's account; it carries a payee name and a reference, and no merchant category code. A block built on the code has nothing to act on.

Debit card payment to a casino — Carries a merchant category code: Yes · Caught by a card-based block: Yes
Manual bank transfer to the operator's account — Carries a merchant category code: No · Caught by a card-based block: Not by a card control
Open Banking payment via a provider — Carries a merchant category code: No · Caught by a card-based block: Not by a card control; Revolut says so explicitly
Card purchase inside a provider's window — Carries a merchant category code: Yes, if processed as a card transaction · Caught by a card-based block: Possibly

The last row is the exception to watch. Some providers process a deposit as a card transaction rather than as a Faster Payment; a block that catches cards would catch that. The cashier label does not tell you which, and the bank statement afterwards does.

Each lender's own description of its block

Barclays — What the bank's own page says the block is: A control on card payments, in the "Your Cards" section of the app under gambling · Transfer mentioned?: No
HSBC — What the bank's own page says the block is: A gambling restriction applied by merchant category code; the bank warns it may not recognise every transaction · Transfer mentioned?: No
Starling — What the bank's own page says the block is: A gambling block among the card controls · Transfer mentioned?: No
Revolut — What the bank's own page says the block is: A gambling block by merchant category code, off by default; the bank states it does not affect bank transfers or payments through third-party apps, and lifting takes up to 48 hours · Transfer mentioned?: Yes: not covered

For Bank of Scotland, Halifax, Lloyds, Monzo, NatWest, RBS and Santander we have the Commission's listing and nothing from the banks' own pages in our sources, so this page makes no claim about what those blocks are built on. A reader at one of those banks has the same test available: open the block's description in the app and look for the word card.

If the description names a card, the block is a card control and a transfer is outside it; if it names the account, the block may reach a transfer, and the only way to be sure is to ask the bank in writing and keep the answer. A dated answer from the bank is worth more than any table on a comparison page, including this one.

Revolut: the one explicit statement

Revolut is not on the Commission's list, and it is the only bank in our sources that addresses transfers directly. Its help page describes a gambling block that works by merchant category code, is switched off by default, takes up to 48 hours to lift once enabled, and does not affect bank transfers or payments made through third-party apps. That is a precise description of the gap every card-based block has and most banks leave unstated: a transfer to a casino, manual or through an Open Banking provider, goes through.

The 48-hour delay is the useful part of Revolut's design and of HSBC's cooling-off period and Monzo's support-only removal: a block that can be switched off in a moment is a decoration, and a block that takes two days to lift is a brake. The delay is the feature, and it is why the tools in the next section are built the same way.

The tools that reach every payment method

GamStop. The national online self-exclusion scheme. Every Gambling Commission licensee operating online must take part; registration is free; the exclusion runs for six months, one year or five years and cannot be cancelled before it ends; and it closes every licensed site at once, whatever payment method you would have used. It covers only sites licensed in Great Britain, which is why operators marketed as outside it are outside the licence, and the Commission's executive director has described such sites as illegal online casinos targeting people who chose to self-exclude.

Device-level blockers. Gamban and BetBlocker block gambling sites and apps on the devices they are installed on, regardless of how a deposit would have been paid, and both are free to UK residents. They reach sites outside GamStop as well as inside it.

The operator's own tools. A Gambling Commission licensee must offer a deposit limit, a time-out and self-exclusion in the account, and must run a financial vulnerability assessment from open data once net deposits exceed £150 in a rolling 30-day period. These act on the account rather than the payment and therefore reach a transfer; an overseas operator offers them at its discretion.

Card-based bank block — Reaches a transfer: Mostly not · Reaches a card: Yes · Reaches sites outside the UK licence: Yes, for card payments
GamStop — Reaches a transfer: Yes · Reaches a card: Yes · Reaches sites outside the UK licence: No
Gamban or BetBlocker — Reaches a transfer: Yes · Reaches a card: Yes · Reaches sites outside the UK licence: Yes
Deposit limit in a licensee's account — Reaches a transfer: Yes · Reaches a card: Yes · Reaches sites outside the UK licence: Not applicable

A combination that works

A bank block alone leaves the transfer route open. GamStop alone leaves unlicensed sites open. A device blocker alone can be uninstalled. Together they cover the three gaps: the bank block stops a card payment on impulse, GamStop closes every licensed site for a fixed period that cannot be shortened, and a device blocker closes the rest on the devices you use. A deposit limit in each licensed account is the fourth layer, and it is the one that acts before the first transfer rather than after.

None of this is a reason to treat a bank block as useless. It is a reason to know what it is. A player who switches one on believing it stops a transfer, and then finds that a transfer went through, has not found a flaw in the bank; the bank's own page said what the block covers, and this page has tried to read it aloud.

What this page does not claim

It does not say that any bank's block catches or misses a transfer unless the bank's own page says so. It does not list a bank's per-payment limits, which we have not verified. It does not describe GamStop as reaching operators outside the licence, because its own page says it does not.

And it does not present any block as a substitute for the decision to set a limit before the first deposit, which is the only control that acts on the player rather than on the payment. You must be 18 or over to gamble in Great Britain; if gambling is causing harm, the National Gambling Helpline, run by GamCare, is free on 0808 8020 133 at any hour.

Frequently asked questions

Which UK banks offer a gambling block?

The Gambling Commission's page lists Bank of Scotland, Barclays, Halifax, HSBC, Lloyds, Monzo, NatWest, RBS, Santander and Starling. Revolut is not on the list but offers one.

Does the block stop a bank transfer to a casino?

At the banks whose pages we read, the block is described as a card control keyed to merchant category codes, and Revolut says its block does not affect bank transfers. A transfer is therefore usually outside the block; we make no claim for banks whose pages we did not read.

What is a merchant category code?

A code assigned to a card merchant by its acquirer that identifies the type of business. Card-based gambling blocks act on payments to merchants with gambling codes. A bank transfer carries no merchant category code.

Can I turn a block off immediately?

Depends on the bank. HSBC applies a cooling-off period before the block can be lifted; Monzo removes it only through its support team; Revolut says lifting takes up to 48 hours. The delay is the point of the design.

What stops a transfer to a casino if I want to be stopped?

GamStop, which closes every Gambling Commission licensee at once regardless of payment method, and a device-level blocker such as Gamban or BetBlocker, free to UK residents, which blocks gambling sites and apps on your devices.

Does an Open Banking deposit count as a card payment?

No. It is a Faster Payment started by a regulated provider from your account. Revolut's statement that its block does not affect payments made through third-party apps describes this route. A provider that processes a deposit as a card transaction would be the exception.

Will my bank know a transfer went to a casino?

The payee name is the operator's company and appears on your statement. The bank's block does not act on it, but the payment is visible, and a licensed operator may later ask for that statement as source-of-funds evidence.
