Our verdict
Monzo Flex suits UK residents who want a free-to-hold Mastercard debit card for travel spending, with a currency conversion fee of 0% and free ATM withdrawals of £200. It is a bank current account rather than a crypto card, so readers buying tokens or holding self-custodied coins will find more elsewhere.

Pros and cons
Pros
- The monthly fee for the current account plan is £0, so the card costs nothing to maintain.
- Currency conversion of 0% compares well with 0.1% at Wise.
- The account covers 38 currencies, with travel use listed among the plan features.
- Help is available on chat, phone and help centre, and the issuer is authorised in the UK by the Prudential Regulation Authority.
- The card runs on mastercard, with a virtual card option (virtual card and travel) for online spending.
Cons
- The card type is debit (debit), so there is no credit line and no interest-free period on purchases.
- The free ATM allowance of £200 sits well below the largest allowances on the site, which reach €2,000.
- The listed audience is kids and business (kids and business), so the plan is not aimed at premium travel spenders.
Who it suits
- UK residents who want a Mastercard debit card with no monthly charge and free currency conversion.
- Travellers who want a free ATM allowance of £200 and a virtual card for online spending abroad.
- Parents and small businesses covered by the listed audience (kids and business).
Who should look elsewhere
- Bitpanda, for anyone who wants a card that sits alongside a crypto platform rather than a UK current account, even though its card also has a monthly fee of €0.
- BMW Card von American Express, for anyone set on a credit card rather than a debit card, which also lists a monthly fee of $0.
- Wise, for readers focused on moving and holding balances in many currencies rather than day to day card spending, with its conversion fee at 0.1%.
Using it abroad
Spending abroad is the strongest part of the offer. The currency conversion fee is 0%, so card purchases in another currency are not marked up above the network rate. Cash is where the ceiling appears: the free ATM allowance is £200, and a trip that leans on cash machines will reach it sooner than one that pays by card. The card runs on mastercard, so the network in use does not change between home and abroad, which keeps the practical question simple: how much cash the trip actually needs.
Where it sits among rivals
The fees readers check most put Monzo Flex at 1 of 379 brands on monthly fee and 1 of 237 brands on currency conversion fee. Cash is the measure that pulls the card down the table: 14 of 104 brands rank higher on free ATM withdrawals. The pattern matches how the card gets used, with no charge for holding it or converting money and a limit that only shows up when a reader needs notes.
Who runs it
Monzo Flex is issued by Monzo Bank Limited (Monzo Bank Limited), a bank headquartered in the UK (GB) and founded in 2015. It is authorised in the UK by the Prudential Regulation Authority, reference 730427, so the account is run by a bank rather than an exchange or a card programme. Support runs on chat, phone and help centre, which means a card that stops working abroad can be sorted by phone as well as in app.

Frequently asked questions
What does Monzo Flex cost to hold each month?+
The monthly fee is £0 on the current account plan, so there is no charge for keeping the card open month after month. Spending abroad adds nothing either, because the currency conversion fee is 0%. The cost that does apply is cash: withdrawals beyond the free ATM allowance of £200.
Is there a fee when I spend in another currency?+
The currency conversion fee is 0%, so foreign purchases convert without a marked-up charge. Wise's conversion fee is 0.1%, which is higher. Monzo Flex also holds 1 of 237 brands on that measure, and the account covers 38 currencies for holding and spending.
How much cash can I take out free?+
The free ATM allowance is £200. That is above the site median of €0 and puts Monzo Flex at 14 of 104 brands on this measure, while the largest allowances reach €2,000. Cash-heavy travellers should check that ceiling before planning around free withdrawals.
What kind of card is it and which network runs it?+
It is a debit card, so spending comes straight out of the current account balance rather than a credit line. The card runs on the mastercard network, which is the same at home and abroad. There is no interest-free period on purchases, and the monthly fee for the current account plan is £0.
Who regulates Monzo Flex?+
The card is issued by Monzo Bank Limited (Monzo Bank Limited), headquartered in the UK and founded in 2015. It is authorised in the UK by the Prudential Regulation Authority, reference 730427, so the balance sits with a regulated bank rather than an exchange or a prepaid programme.
How do I get help if my card stops working?+
Support runs on chat, phone and help centre, so a blocked card can be sorted by in-app chat, by phone or through the help centre rather than at a branch. The phone channel matters most to a traveller whose card has stopped working outside UK opening hours, and the help centre covers the questions that do not need an agent.
Does the plan include a virtual card?+
The plan lists a virtual card and travel use among its features (virtual card and travel), which suits readers who want a separate card number for online spending and who pay in foreign currencies. The card behind it is a debit card on mastercard, so an extra virtual number does not change how the money is held.
Who is the account aimed at?+
The plan targets kids and business users (kids and business), so the pricing is built around family and company spending rather than premium travel tiers. Support is the same either way, on chat, phone and help centre. Readers who want a card tied to digital assets would be better served by a platform built for that, since this card draws on a bank current account.
