Buy Now Pay Later Ireland: Klarna vs Revolut vs Humm

Splitting a big purchase into manageable instalments sounds like a sensible idea, but buy now pay later (BNPL) products often come with catches that marketing materials gloss over. One in four Irish shoppers have considered using BNPL for purchases outside their budget, according to Central Bank research.

Top Providers: Klarna, Affirm, Revolut · Popular Features: Interest-free instalments, split payments · Ireland Availability: Klarna, Revolut, Humm · Common Merchants: Currys, Very, online shops · Approval Factors: Credit check varies by app

What is the best buy now pay later company?

Three providers dominate the Irish BNPL landscape, each taking a different approach to how you pay and what you pay back. Klarna leads on popularity, Humm targets bigger purchases with more flexible terms, and Revolut integrates with its existing account ecosystem.

Klarna vs Affirm vs Revolut

Klarna holds the top spot as the most-downloaded BNPL app in Ireland from 2021 through 2025, according to Statista data. Its “pay in 3” model splits purchases into three equal payments spaced 30 days apart, with no interest charged if you pay on time. Late fees can still bite, though.

Revolut Pay Later charges a 1.65% fee on the purchase amount. For a €120 item, that works out to €1.98 in fees, with the remaining balance split into two payments of €40.99 each, according to Revolut’s own calculations. The APR example given is 21.4%.

Affirm remains more dominant in the US market, with limited Irish merchant integration compared to Klarna. Its model typically allows instalments over 3-24 months with transparent interest rates displayed before checkout.

Factors for best choice in Ireland

The right provider depends on your purchase size, repayment comfort, and whether you want interest-free terms. Klarna wins for short-term, smaller purchases where you can commit to three payments. Humm suits larger buys where you might need 6 months to 6 years to pay back, up to €30,000, as noted by The Times.

Who are the biggest buy now pay later providers?

The Irish BNPL market features both global players that entered via retailer partnerships and homegrown services that evolved through acquisitions.

Top BNPL in USA and Ireland

Globally, Klarna and Afterpay lead the market. In Ireland specifically, Klarna, Revolut, and Humm hold the strongest positions. The market is projected to reach $2.21 billion by 2029 according to BusinessWire analysis.

Market leaders like Klarna and Humm

Klarna arrived in Ireland in November 2021 and quickly dominated app downloads. Humm, now under the Australian Flexigroup umbrella after acquiring FlexiFi in 2021, operates differently—it offers credit up to €30,000 and partners with sectors including dental and veterinary clinics for instalment payments, per BusinessWire research.

The implication: Klarna is the go-to for everyday retail, while Humm targets bigger-ticket purchases where spreading costs over years makes more sense.

What’s the easiest buy now pay later app to get approved for?

BNPL providers typically perform softer credit checks than traditional lenders, making approval easier to obtain than a credit card, according to Shopify’s analysis of the Irish market. That said, approval is never guaranteed.

No credit check options

No BNPL provider operating in Ireland offers truly zero credit checks—the Central Bank requires some form of affordability assessment. Claims of “no credit check” typically mean no hard inquiry that impacts your credit score unless you miss payments.

Instant approval in Ireland

Approval speed varies. Klarna and Revolut process applications within seconds at checkout. Humm requires more documentation for higher credit limits, since it lends larger amounts over longer periods.

One quirk worth noting: according to Irish Times reporting, some shoppers applying after midnight have been turned down, suggesting approval algorithms may have reduced capacity at certain times.

How does Revolut Buy Now Pay Later work?

Revolut’s Pay Later feature integrates directly with your existing Revolut account, letting you split eligible purchases made through the app or at partnered retailers.

Setup steps

To use Revolut Pay Later, you need an active Revolut account in Ireland. Within the app, you select “Pay Later” at checkout on eligible purchases. The system calculates a 1.65% fee added to your total, then splits the amount into two equal payments.

For example, a €120 purchase breaks down as €40 upfront, followed by two payments of €40.99 each, as shown in Revolut’s own product page.

Restrictions in Ireland

Not all Revolut users in Ireland automatically qualify. The feature requires account verification and may depend on your account history and spending patterns. Revolut has reportedly been expanding its Irish offerings, with credit cards and mortgages reportedly in development alongside the existing BNPL product.

The trade-off: Revolut’s 1.65% fee and 21.4% APR example mean this is not the interest-free option some users might expect. If you’re looking to avoid interest entirely, Klarna’s pay-in-3 model is the more cost-predictable choice.

Are Klarna and Humm the same?

No—despite sometimes being mentioned in the same sentence, Klarna and Humm operate quite differently and are separate companies with distinct business models.

Key differences

Klarna focuses on retail purchases with short-term, interest-free instalments. Humm targets larger purchases across more sectors and charges interest ranging from 0% to 14.99% depending on the retailer, plus application fees of €10-€50 and monthly account fees of €1-€20, according to Irish Times analysis.

For a €2,700 treatment financed through Humm, a shopper could pay a €40 application fee, twelve monthly payments of €231, plus €3.50 account fees per month—that’s €42 in account fees on top of the purchase itself.

Humm rebranding history

Humm originated as a Flexifi subsidiary, launched in Ireland, and now operates under Australian parent company Flexigroup after acquiring the domestic FlexiFi service in 2021. The brand consolidated under the Humm name, which has grown to become the third-largest BNPL provider in Australia after Afterpay and Klarna, as noted by Verdict Magazine.

The pattern: Klarna is the lifestyle retailer of BNPL—convenient, trendy, interest-free if you’re disciplined. Humm is the credit card alternative—higher limits, longer terms, but interest and fees add up quickly.

Four providers, four very different approaches. Here’s how they stack up across the features that matter most for Irish shoppers.

Getting started with any BNPL service in Ireland involves a few consistent steps, though specifics vary by provider.

1. Download the app and create an account. Klarna, Revolut, and Humm all require account creation with identity verification.
2. Complete the affordability check. Providers assess your spending history and account activity—hard credit checks are not standard.
3. Shop at a partnered retailer. BNPL only applies at merchants that have integrated the specific service.
4. Select BNPL at checkout. Choose the instalment option before confirming payment.
5. Set up repayment method. Link a debit card or bank account for automatic payments.
6. Track your instalments. Missed payments trigger late fees and potential credit impact.

BNPL services have matured in Ireland, but the industry still operates with significant variation in how much borrowers actually pay back. The Central Bank’s research showing one in four shoppers considering BNPL for out-of-budget purchases suggests the convenience appeal isn’t fading. What varies is how transparent each provider is about the true cost of credit.

For Irish shoppers, the choice between Klarna, Revolut, and Humm ultimately comes down to purchase size and repayment discipline. Klarna’s interest-free model rewards those who pay within three instalments. Revolut works for existing account holders who want a quick fee-based split. Humm serves customers financing bigger purchases over years—but the numbers deserve close scrutiny before signing up.

For anyone considering BNPL at Currys or similar retailers in Ireland, the decision is clear: use Klarna for short-term instalments you can clear, compare the Revolut 1.65% fee against your purchase size, and treat Humm’s €30,000 limits as serious credit commitments with interest and fees attached.
