What Is Buy Now Pay Later (BNPL)?

Buy Now Pay Later (BNPL) is a short-term financing option that lets you receive goods immediately and spread the cost over a set period β€” typically in 3–4 interest-free instalments over 6–8 weeks, or as a deferred single payment after 30 days.

The major BNPL providers in the UK include Klarna (the market leader, with 18 million UK users), Clearpay (owned by Block/Square), Laybuy, and PayPal Pay in 3. Many are integrated directly into retailer checkout flows β€” making it easy to use without thinking carefully about the implications.

BNPL feels like "free money" because there's no immediate interest charge. But it's still debt β€” and increasingly, debt that affects your credit score. The FCA is bringing BNPL under formal regulation in 2025, which means the same rules that apply to credit cards will apply to Klarna and Clearpay. This is a significant change that every BNPL user needs to understand.

How BNPL Works

Most popular

Pay in 3 Instalments

Klarna "Pay in 3", Clearpay, PayPal Pay in 3. Purchase split into 3 equal payments. First payment taken immediately; others at 2-week intervals. Usually interest-free if paid on time. Late fees if you miss an instalment.

Flexible

Pay Later (30 Days)

Klarna "Pay Later in 30 Days". No payment taken now β€” full amount due in 30 days. Designed for trying items before committing. Interest-free if paid within 30 days; late fees and potential credit impact if missed.

Longer term

Financing (3–36 Months)

Klarna Financing, Laybuy. Longer repayment plans, often with interest. Regulated credit agreements that already appear on credit files. Work similarly to personal loans β€” full credit check required.

New

Virtual Credit Cards

Some BNPL providers (Klarna) issue a virtual card usable anywhere. Allows BNPL at retailers that don't formally offer it. Subject to the same risks as other BNPL β€” and increasingly regulated.

How BNPL Affects Your Credit Score

The credit impact of BNPL is changing rapidly due to FCA regulation coming into effect in 2025. Here's where things currently stand:

  • Pay in 3 (Klarna, Clearpay): A soft search is performed when you use these products β€” visible to you on your credit file but not to most lenders. Missed or late payments are reported as negative entries to credit bureaus.
  • Klarna Financing (3–36 months): Already a regulated credit product with a full hard search and reporting to credit bureaus. Shows on your credit file as a loan.
  • From 2025 onwards: New FCA rules require all BNPL providers to conduct affordability checks and report all accounts (positive and negative) to credit bureaus. This means using BNPL responsibly could build credit β€” but missing payments will definitely damage it.
⚠️ Accumulation risk

The ease of BNPL can lead to using it across multiple retailers simultaneously β€” multiple payments on different schedules across different apps. Research by the FCA found that 1 in 4 BNPL users struggle to keep track of what they owe. This is the most common way BNPL leads to missed payments and credit damage.

BNPL vs Credit Cards: Consumer Protection Gap

A critical difference most consumers don't know: Section 75 of the Consumer Credit Act gives credit card holders a legal right to claim against the card provider if a retailer fails to deliver goods, goes bust, or misrepresents a product β€” for purchases between Β£100 and Β£30,000. This protection covers holidays, electrical goods, and thousands of purchases every year.

BNPL does not carry Section 75 protection. If you buy a Β£500 item using Klarna, the retailer goes bust, and the item never arrives β€” you have no legal recourse against Klarna the way you would with a credit card. Your dispute is with the retailer only, and if they're insolvent, you may have lost your money.

When BNPL Makes Sense (and When It Doesn't)

Use it when

BNPL can be sensible

You're buying a specific item you can definitely afford, and BNPL simply spaces out a payment you'd make anyway. You have Direct Debits set up so instalments are never missed. The item is under Β£100 where Section 75 wouldn't apply anyway. You have no existing BNPL balances outstanding.

Avoid it when

BNPL is risky

You're buying something you couldn't afford without BNPL β€” it's enabling spending beyond your means. You already have multiple BNPL purchases outstanding. The purchase is over Β£100 and you'd benefit from Section 75 protection via a credit card. You're planning a mortgage application in the next 12 months β€” BNPL searches can complicate affordability assessments.

Frequently Asked Questions

Yes, potentially. Mortgage lenders assess affordability and debt levels. Active BNPL commitments appear as liabilities and reduce your disposable income assessment. Multiple recent BNPL searches can look like financial stress to underwriters. In the 3–6 months before a mortgage application, minimise BNPL use and ensure any outstanding balances are cleared. Some lenders are more BNPL-tolerant than others β€” a whole-of-market mortgage broker can advise which lenders view BNPL most favourably.
As of 2025, the FCA is bringing the most popular BNPL products under formal regulation for the first time. Previously, short-term 0% instalment credit was exempt from Consumer Credit Act regulation. Under the new rules, BNPL providers must conduct proper affordability checks, provide clear information about terms, have a complaints process, and report to credit bureaus. This brings BNPL broadly in line with credit card regulation.
Yes β€” if you return an item purchased with BNPL, the refund is typically applied to your outstanding BNPL balance, reducing or eliminating what you owe. If you've already paid some instalments, the refunded amount should be returned to your original payment method. Keep proof of return and contact the BNPL provider directly if the balance doesn't update within 5–10 days of the retailer processing the return.
