Quick summary
For UK Shopify merchants, the three main BNPL options are Klarna (widest consumer recognition, 5.99% plus 20p per transaction), Clearpay (strong in fashion and beauty), and Laybuy (lower fees, fewer users). FCA regulation introduced in 2025 requires BNPL providers to carry out affordability checks, which has changed approval rates for some demographics.
A customer adds a £180 item to their basket. They get to checkout, see the total, and leave. No error. No technical problem. Just a price that felt too large in the moment.
Buy Now Pay Later (BNPL) was designed to solve exactly this. And for many UK Shopify merchants, it works. But choosing the wrong provider, setting it up incorrectly, or misunderstanding the new FCA rules can cost you more than you gain.
Here is what you need to know before you add BNPL to your store.
How Big Is BNPL in the UK and Does It Actually Lift Conversion?
The UK is the largest BNPL market in Europe. In 2024, BNPL transactions accounted for approximately £30 billion in UK ecommerce spend, according to Statista. Klarna alone processed over £11 billion in UK transactions that year.
The conversion and AOV data is consistent across providers and independent research:
- BNPL shoppers have an average order value 20-30% higher than credit card shoppers on the same store (Klarna merchant data, 2024).
- Offering BNPL at checkout increases conversion rate by an average of 6-8% across UK ecommerce (PPRO, 2024 Global Payments Report).
- 40% of UK adults aged 25-44 used BNPL at least once in 2024 (FCA Financial Lives Survey, 2024).
The benchmark that matters: a 6-8% conversion lift is significant for any store. If your store currently converts at 2.5%, adding BNPL could push that to 2.65-2.7% without changing anything else. At scale, that compounds.
How Do Klarna, Clearpay, Laybuy, and PayPal Pay in 3 Compare?
| Provider | Product | Merchant Fee | Approval Rate | Chargeback Risk | Dashboard Quality |
|---|---|---|---|---|---|
| Klarna | Pay in 3, Pay in 30, Financing | 0.99% + 20p to 2.49% + 20p per transaction | High (soft credit check) | Medium | Excellent |
| Clearpay | Pay in 4 (fortnightly) | ~6% per transaction | Medium-High (proprietary model) | Low (Clearpay absorbs fraud) | Good |
| PayPal Pay in 3 | Pay in 3 (monthly) | Included in standard PayPal rate | High (existing PayPal users) | Medium | Basic |
| Laybuy | Pay in 6 (weekly) | ~3.5-4% per transaction | Medium | Low-Medium | Moderate |
A few notes on the table above:
Klarna is the market leader in the UK for BNPL in ecommerce and has the strongest brand recognition among shoppers. Its merchant fee varies by product and risk profile. Pay in 3 (three equal monthly payments) is the most widely used. The merchant portal is comprehensive, with conversion analytics, segment data, and A/B testing tools. Klarna integrates directly with Shopify via the App Store.
Clearpay (known as Afterpay in other markets) charges a higher percentage fee but absorbs fraud and chargeback risk, which makes it more predictable for merchants. It is well suited to fashion and beauty merchants. The fortnightly payment structure appeals to customers who prefer more frequent smaller amounts over monthly lump sums. Clearpay integrates with Shopify directly and supports on-site messaging widgets.
PayPal Pay in 3 is available to merchants already using PayPal at checkout with no additional integration required. The approval rate is high for existing PayPal account holders, but the product is less prominent in the checkout flow than Klarna or Clearpay, and the marketing widget options are limited. It works best as a supplementary option rather than a primary BNPL offering.
Laybuy is a New Zealand-founded product with a UK merchant base, offering six weekly payments rather than three or four. The longer repayment window appeals to higher-ticket items. However, Laybuy has had financial instability in the past (it entered administration in 2022, was acquired, and relaunched). Check current trading status before signing up.
What Did the FCA BNPL Regulation Changes Mean for Merchants?
The Financial Conduct Authority brought BNPL products under formal regulation in 2025. This is the most significant structural change to the UK BNPL market since its rapid growth in 2020-2022.
What changed and what it means for you:
Affordability checks are now mandatory. BNPL providers must conduct regulated credit assessments before approving a BNPL transaction. In practice, this means some customers who previously would have been approved will now be declined. Klarna and Clearpay both updated their approval models ahead of the regulation taking effect.
Pre-contract information requirements. Customers must receive clear, standardised information about the credit agreement before completing a BNPL purchase. This affects how checkout pages must present BNPL information, and providers have updated their widgets to comply.
Complaints handling obligations. If a customer disputes a BNPL charge, the process is now formally regulated. Merchants need to be aware that chargeback disputes involving BNPL are handled through the provider, not directly through the card network. Response times and procedures differ by provider.
What you need to do as a merchant: ensure your on-site BNPL messaging uses the copy approved by your provider, do not make your own claims about approval rates or credit terms, and link to the updated terms provided by Klarna, Clearpay, or your chosen provider. Your provider will have sent updated merchant documentation. If you have not reviewed it, do so before your next major campaign.
How Do You Display BNPL Messaging on Product Pages?
BNPL works best when the customer sees the instalment amount before they add to basket. Showing "or 3 payments of £32" alongside the £95 price removes the price shock early in the journey.
All major providers offer on-site messaging widgets for Shopify:
Klarna On-Site Messaging (free, via Klarna's Shopify app): places a small text snippet below the price on product pages showing the instalment amount dynamically. Fully configurable in the Klarna merchant portal. You can A/B test messaging variants and track click-through rates to checkout.
Clearpay Messaging Widget (free, via Clearpay's Shopify integration): similar functionality, with a "more info" popup explaining the payment schedule. The widget updates dynamically based on the product price.
PayPal Pay Later Messaging (free, via PayPal's Shopify integration): available but less visually prominent by default. Worth configuring if PayPal is your primary checkout, but less impactful as a standalone BNPL signal.
Placement recommendations: below the price (primary), above the add-to-cart button (secondary), and in the cart/checkout sidebar. Merchants who display BNPL messaging in all three locations see higher BNPL uptake than those who display it only at checkout.
Which Product Price Points Benefit Most from BNPL?
BNPL conversion uplift is not uniform across price points. The data from Klarna's UK merchant reports and independent research points to a clear pattern:
| Price Range | BNPL Impact |
|---|---|
| Under £30 | Minimal. Customers rarely need instalments at this price point. |
| £30-£80 | Moderate. Some uplift, particularly for fashion and accessories. |
| £80-£300 | Strong. This is the sweet spot for BNPL conversion. Most studied uplift data sits here. |
| £300-£1,000 | High. BNPL is often the primary reason a customer converts. Financing products (e.g., Klarna's 6-24 month options) become relevant here. |
| Over £1,000 | Klarna Financing or specialist credit is needed. Standard Pay in 3 limits often do not cover this range. |
If your average order value is under £50, BNPL will not be a meaningful growth lever. If your AOV is between £80 and £300, it is one of the highest-ROI checkout changes you can make.
What Is the Chargeback Risk with BNPL?
The chargeback dynamic with BNPL is different from standard card transactions.
When a customer disputes a BNPL purchase, the dispute is filed with the BNPL provider, not directly with Visa or Mastercard. Each provider has its own dispute resolution process:
- Clearpay: absorbs fraud losses. If a transaction is fraudulent, the merchant is not charged back. This is a meaningful benefit given Clearpay's higher transaction fee.
- Klarna: merchant is responsible for chargebacks related to product disputes (not as described, not received). Fraudulent transactions handled by Klarna are typically covered. The Klarna Merchant Protection programme outlines the specific conditions.
- PayPal Pay in 3: follows PayPal's standard dispute resolution process, which is favourable to merchants who can provide proof of delivery and accurate product descriptions.
For merchants with a high return rate or significant "not as described" claims, Clearpay's chargeback absorption model offers the most financial predictability, even at its higher transaction fee.
Key Actions to Take Now
- Check your average order value. If it is between £80 and £300, BNPL is worth prioritising. If it is under £50, address conversion fundamentals first.
- Install Klarna via the Shopify App Store and configure on-site messaging on your product pages, cart, and checkout. This takes approximately two hours.
- Add Clearpay as a second BNPL option if your customers are predominantly in the 25-45 age bracket or in fashion, beauty, or homewares categories.
- Review the updated FCA-compliant terms from your BNPL provider and ensure your on-site copy uses their approved messaging, not your own.
- Monitor BNPL share of checkout in your payment analytics for the first 60 days after launch and compare AOV for BNPL versus non-BNPL orders.
- Configure messaging in three locations: below the product price, above the add-to-cart button, and in the cart drawer.
Frequently Asked Questions
Does offering BNPL increase my chargeback rate?
It depends on the provider. Clearpay absorbs fraud chargebacks entirely. Klarna and PayPal Pass dispute responsibility for product-related claims back to the merchant. Overall, industry data does not show a significant increase in total chargebacks for merchants adding BNPL, provided products are accurately described and fulfilment is reliable.
Can I offer multiple BNPL providers at once?
Yes, and many UK merchants do. Klarna and PayPal Pay in 3 are a common pairing. Displaying both gives customers the option of their preferred provider and increases the likelihood that at least one will approve any given customer. Avoid displaying more than three BNPL options to prevent checkout confusion.
Do I need to change anything after the FCA regulation changes in 2025?
Your BNPL provider will have updated their Shopify integration to comply. The primary merchant-facing requirement is using their approved on-site messaging and linking to their updated terms. Review the documentation sent by your provider and, if in doubt, contact their merchant support team.
Is there a minimum order value for BNPL?
Each provider sets its own minimum. Klarna's minimum for Pay in 3 is typically £35. Clearpay's is £1 with a maximum per transaction of around £800 (varies by merchant agreement). PayPal Pay in 3 requires a minimum of £30 and a maximum of £2,000.
