Oddly Likely verdict
Monzo's gambling policy is a non-event by design: there is no blanket prohibition in its help centre, gambling-coded Mastercard payments process like any other purchase, and there is no equivalent of N26's 3% surcharge or any documented gambling-specific FX markup. The bank's actual answer to gambling risk is the opt-in Gambling Block: switch it on in the app and it declines gambling-merchant-coded card payments instantly. Where Monzo distinguishes itself from Revolut's fixed 48-hour cool-down is the setup step — you choose your own cool-down when you enable it, anywhere from 2 days to a year, and neither the block nor the timer can be shortened once it is running.
The friction is deliberate and, for anyone who has previously told Monzo about gambling harm, it gets stricter still: turning the block off then requires contacting support directly rather than a self-service tap. Two honest limits keep this from being a total wall — it only intercepts card payments, so bank transfers, Direct Debits, and non-card wallet spend (PayPal without a gambling code, crypto coded under MCC 5815) pass through untouched, and a merchant that skips the correct gambling category code can slip past it entirely (Monzo asks customers to report those). Winnings still land as ordinary card refunds, typically the next business day, because the block was never built to catch money coming back in.
What stands out
- No gambling-specific fee or surcharge: standard Mastercard FX and card charges apply to gambling-coded spend exactly as they would to any other purchase — nothing like N26's 3% add-on.
- The opt-in Gambling Block turns on instantly and forces a user-chosen cool-down of 2 days to 1 year before it can come off — longer and stickier than the fixed 48-hour window on Revolut's equivalent.
- If gambling harm has previously been disclosed to Monzo, disabling the block requires contacting support directly instead of a self-service toggle — an extra deliberate friction step most competitors skip.
- Refunds and withdrawals return as ordinary card refunds, typically landing the next business day and fee-free, and the card-only block never intercepts money coming back in.
Watch points
- The Gambling Block is opt-in and off by default — until a customer switches it on, gambling-coded Mastercard payments process exactly like any other card purchase, with no bank-side restriction.
- Coverage is card-payments only: bank transfers, Direct Debits, and non-card wallet spend (PayPal transactions without a gambling code, or crypto purchases coded under MCC 5815) all pass through regardless of the block's setting.
- A merchant that fails to use a correctly-coded gambling category can bypass the block outright — Monzo relies on customers reporting mis-coded merchants after the fact rather than catching every case automatically.
- Monzo operates inside the single UK Gambling Commission regime rather than the multi-country EU footprint N26 and Revolut cover, so its rules are calibrated to UK-licensed betting, not an offshore book.
Monzo's trade is the cleanest in this review class: zero gambling fee for anyone who leaves the block off, and for anyone who switches it on, a cool-down of up to a year that beats every other neobank's self-exclusion tool for stickiness. Set the cool-down long if the point is to actually stop, not just to pause.

Monzo FAQ
Does Monzo allow gambling transactions?
Yes, by default. Monzo's help centre documents no blanket prohibition on gambling-coded card transactions — they process normally for adult accounts unless the customer has switched on Monzo's own Gambling Block. There is no gambling-specific fee attached either way.
Does Monzo have a gambling block feature?
Yes. The opt-in Gambling Block declines card payments coded to gambling merchants and, uniquely in this review class, lets the customer set their own cool-down when enabling it — anywhere from 2 days to a year — with no early exit once it starts.
How long does Monzo's Gambling Block last?
As long as you set it for. When you enable the block you choose a cool-down between 2 days and 1 year; neither the block nor the timer can be shortened until that period elapses, and if gambling harm has previously been disclosed to Monzo, turning it off afterwards requires contacting support rather than a self-service tap.
Can I use my Monzo card on betting sites like BetOnline?
Wherever a verified partner takes Mastercard deposits, a Monzo card behaves like any other Mastercard — no Monzo-side surcharge and no default restriction. Check each partner's card row on its payment review for the cashier's own fees and limits, which sit on top of whatever Monzo does or doesn't charge.
