Is buy now pay later bad for your credit score?

The short answer

Buy now pay later (BNPL) isn't automatically bad for your credit score. Used rarely and paid on time, it may make little difference. But it is borrowing, providers can report your plans and missed payments to credit reference agencies, and lots of plans at once can make lenders nervous. The risk isn't the first plan. It's the fifth one you forgot about.

What changed on 15 July 2026

From 15 July 2026, the Financial Conduct Authority (FCA) regulates the most common type of BNPL, which it calls Deferred Payment Credit. According to the FCA, that means:

• Affordability checks. Lenders must check whether you can afford to repay before you take out an agreement.
• Clear information up front. How much you're borrowing, when repayments are due, how much each one is, and how much any late fee will be.
• Help if you struggle. If you miss payments, firms need to contact you and explain what it means.
• Somewhere to complain. If the lender doesn't sort a problem out, you can go to the Financial Ombudsman Service.
• Section 75 protection is available, which can help if something you bought is faulty or never arrives.

An affordability check can involve looking at your credit file, so applying for a plan may now leave a mark on your file. Check the provider's terms to see what kind of search they do.

How BNPL can affect your file

There are three ways it can show up:

• The plans themselves. Providers can report your BNPL plans to credit reference agencies. Other lenders may see that you have several on the go.
• Missed payments. Missing a payment can be reported, and that's the bit that really hurts. Late payment markers can stay on your file for years.
• Collections. If a debt goes unpaid long enough, it can be passed on, and a default can be recorded.

A one-off plan you pay on time is very different from a stack of them. Mortgage lenders in particular may ask about regular BNPL use when they look at your spending.

The real costs

Most BNPL plans charge no interest if you pay on time. The costs come from:

• Late fees, which you'll now be told about before you sign up;
• Spending more than you planned, because "only £30 today" feels smaller than "£90";
• Stacking, where lots of small plans add up to one large monthly bill you didn't budget for.

Compare the total cost, not the friendly instalment. Our lesson Total cost vs APR shows how to do it in one line of maths, and Buy now, cry later lets you play through Mo's BNPL month.

Four questions before you click "pay in 3"

• Would I buy this today if I had to pay in full? If not, BNPL is just making a "no" feel like a "yes".
• What else is already due? Add up every plan you have open.
• Is the money definitely there on each due date? Set a calendar reminder for each payment.
• What happens if I miss one? Read the late fee, now that they have to show you.

Already struggling?

Talk to the provider early. Under the new rules they have to explain your options. BNPL is a non-priority debt, so if money is tight, rent, council tax and energy come first.
