How bank gambling blocks work
Every card payment carries a merchant category code (MCC) that describes the type of business. Gambling merchants use a specific code. When you switch on a gambling block, your bank declines any card payment with that code, whether it's an online casino, a bookmaker or a lottery site.
Most banks also add a cooling-off period before a block can be removed, commonly 48 hours or more. That delay is deliberate: it gives you time to think twice before turning the block off.
Which UK banks offer a gambling block?
Most major UK banks and card providers offer one in their app or online banking. They include Barclays, HSBC, Lloyds, Halifax, NatWest, Santander, Nationwide, TSB, Monzo, Starling, Revolut and Chase UK. You'll usually find it under card settings, card controls or spending controls. If you can't find it, contact your bank. Many can switch it on for you over the phone.
Tip: If you have more than one bank account or card, switch on the block for each of them. One unblocked card leaves a gap.
What a bank block might not catch
- Open Banking payments: Pay by Bank and Trustly don't use card merchant codes, and banks differ in whether their block covers them.
- E-wallets: payments routed through PayPal, Skrill or Neteller may not be identified as gambling by your bank.
- Prepaid vouchers and phone billing: Paysafecard and pay by phone bypass your bank entirely.
- Unlicensed sites: offshore casinos sometimes miscode their payments to get around blocks.

Removing a block
If you decide to turn a block off, most banks will make you wait out the cooling-off period before payments go through. Some may ask you to call. If you're removing a block on impulse, perhaps to chase a loss, that's a good moment to stop and talk to someone. Our responsible gambling page lists free support services.
Frequently asked questions
How do I block gambling on my bank card?
Open your banking app and look for card controls or spending controls. Most UK banks have a gambling block you can switch on instantly. You can also ask your bank to do it for you.
Can I remove a gambling block straight away?
Usually not. Most banks apply a cooling-off period, commonly 48 hours or more, before a block is lifted.
Does a gambling block stop PayPal gambling payments?
Not always. Payments routed through e-wallets may not be identified as gambling by your bank. Combine your block with GAMSTOP and blocking software.
