Buy Now Pay Later was sold to the British public as a convenience. A frictionless way to split a £60 jumper into three manageable chunks, or defer a sofa payment until after payday. What nobody mentioned clearly enough was that millions of people would end up using it for groceries, utility bills, and everyday essentials, stacking multiple BNPL agreements simultaneously, and doing so with almost none of the legal protections that come with a standard credit card. BNPL debt UK-wide has grown at a pace that genuinely startled even the FCA when it finally looked closely at the numbers.
I’ve been watching this one build for a couple of years, and the thing that keeps striking me is how invisible the problem looks from the outside. There’s no obvious credit card bill. No single statement. Just a patchwork of Klarna instalments, Clearpay agreements, and Laybuy deductions quietly leaving accounts in rotation throughout the month. For a significant portion of users, particularly those between 18 and 34, that patchwork has become genuinely difficult to track.
Just how large has BNPL debt UK borrowing become?
The figures are striking. The FCA’s own consumer guidance on Buy Now Pay Later acknowledges that around 10 million UK adults used a BNPL product in 2023 alone. By 2026 that number has only grown, with the sector now estimated to be worth over £30 billion annually in the UK. Klarna, by far the dominant player, reported processing billions of pounds in UK transactions per year. Clearpay, PayPal’s Pay in 3, and a raft of smaller competitors have added to the total.
What makes this different from standard consumer credit isn’t the scale alone, it’s the way it accumulates. A single Klarna account is manageable. But Citizens Advice found in research published in 2024 that one in ten BNPL users had four or more active agreements running at once. There’s no central register, no credit check in the traditional sense for most providers, and until very recently no obligation to report to credit reference agencies. You could max out five BNPL accounts and walk into a mortgage application looking perfectly clean on paper.
Why FCA regulation took so long to get here
This is the part that genuinely baffles me. The FCA flagged BNPL as a risk as far back as the Woolard Review in 2021. That report was blunt: unregulated BNPL was expanding rapidly, disproportionately used by financially vulnerable people, and creating debt that was effectively invisible to the credit system. The recommendation was to bring it under regulation quickly.
What followed was five years of consultation, draft legislation, lobbying from the fintech sector, and a regime change at Westminster. The Treasury consulted. Draft bills were produced, shelved, revised. The industry argued that heavy-handed regulation would kill a product that genuinely helps consumers manage cash flow. The FCA argued for proper affordability checks and clearer disclosure. Neither side moved fast enough, and in the gap, millions of people kept borrowing without meaningful protection.
Regulation is now inching forward. The government confirmed in early 2025 that BNPL firms will be required to carry out affordability checks and come under FCA supervision, with the framework expected to be in force by late 2026 or early 2027. Better late than never, perhaps, but by then the consumer harm has already accumulated across years of unchecked growth.
Who is actually getting hurt by BNPL debt?
The picture painted by debt charities is uncomfortable. StepChange, one of the UK’s largest debt advice organisations, reported that BNPL debt featured in a growing proportion of their client cases from 2023 onwards, often sitting alongside council tax arrears, energy debt, and credit card balances. The people most likely to be struggling aren’t necessarily reckless spenders; they’re people who used BNPL to cover basics during the cost of living crisis and found the repayments piling up faster than expected.
Young women are disproportionately represented in the data. Fashion and beauty retail drove enormous BNPL adoption, partly because providers embedded themselves so deeply into checkout flows that opting out required actively looking for an alternative. Some retailers made BNPL the default payment option. It’s a pattern you see across hidden risk areas in consumer markets, and it’s worth noting that the FCA has had to develop expertise across wildly different product categories where risks are obscured from view. Asbestos Compliance Solutions has written about how even the beauty sector can harbour hazards consumers never expect to encounter, and the same logic applies here: the risk is real, it just doesn’t look like one at the point of purchase.
There are also real mental health consequences. A 2024 report from the Money and Mental Health Policy Institute found that people with problem BNPL debt were significantly more likely to report anxiety and sleep disruption related to finances. The constant drip of small repayments created a background financial anxiety that was distinct from the experience of holding a single larger debt.
What the BNPL firms say in their defence
To be fair, the providers aren’t entirely wrong when they argue the product has genuine utility. For someone who needs a new laptop for work and can genuinely afford three equal payments spread over six weeks, it is a more transparent and lower-cost option than a credit card charging 25% APR. Klarna in particular has invested in in-app budgeting tools and repayment reminders. Some of the worst practices, particularly sending debts immediately to aggressive collection agencies, have been quietly wound down following reputational pressure.
But utility for some users doesn’t resolve the structural problem: the product was designed and marketed aggressively to people who would benefit most from being asked a few harder questions before they checked out. The lack of affordability checks wasn’t an oversight; it was a commercial decision that made onboarding frictionless and conversion rates high.
The broader picture of consumer debt in Britain
BNPL doesn’t sit in isolation. It’s one piece of a wider picture of consumer borrowing that has been under pressure since 2022. We’ve written before about the people being left behind by Britain’s welfare system, and the same demographic often turns to BNPL as a bridging tool when benefits don’t cover essentials. Equally, the millions of economically inactive Britons who’ve dropped out of the labour market entirely are precisely the group with irregular income for whom BNPL repayment schedules become unmanageable quickly.
There’s also a link to the housing crisis. As we’ve covered in our piece on Britain’s broken private rental sector, renters facing unaffordable costs and no long-term security are exactly the kind of financially stretched consumers BNPL targets by default. When you’re spending 40% of your take-home pay on rent, splitting a £100 shop into instalments feels rational. Until it isn’t.
What needs to change right now
The incoming regulation is a start, but it can’t undo the debt already sitting on millions of accounts. What’s needed in parallel is better signposting to free debt advice (StepChange, National Debtline, and Citizens Advice all offer it), genuine transparency in checkout flows so consumers know they’re taking on a regulated credit product, and credit reference agencies that actually reflect BNPL usage so lenders can price risk accurately.
For individuals already juggling multiple agreements, the advice from debt charities is consistent: list everything, consolidate where possible, and speak to a free adviser before things get worse. The stigma around admitting BNPL debt has been substantial precisely because it feels like admitting you couldn’t afford a dress or a pair of trainers. That stigma has kept people quiet and kept debts growing.
Britain is very good at letting financial products rip through the consumer market before the rulebook catches up. We’ve seen it with payday loans, with PPI, with rent-to-own schemes. BNPL is the latest version of that story. The regulation is coming. For a lot of people, it’s already too late to help with the debt they’re already carrying.
Frequently Asked Questions
Is Buy Now Pay Later debt regulated in the UK?
As of 2026, BNPL is in the process of coming under FCA regulation following years of consultation, but the full framework is not yet in force. Most BNPL agreements have historically offered fewer protections than traditional credit products such as credit cards, meaning consumers had limited recourse if things went wrong.
Does using Buy Now Pay Later affect your credit score in the UK?
It depends on the provider and the agreement. Some BNPL firms do now report to credit reference agencies, meaning missed payments can affect your score. However, historically many BNPL debts were invisible to lenders, which created risks for both borrowers and mortgage applicants whose true debt levels were understated.
What can I do if I'm struggling with BNPL debt?
Free debt advice is available from StepChange (stepchange.org), National Debtline, and Citizens Advice. They can help you list your agreements, prioritise repayments, and negotiate with providers. Don’t ignore the debt, as some BNPL firms do refer unpaid balances to debt collection agencies.
Which BNPL providers operate in the UK?
The main providers in the UK market are Klarna, Clearpay, PayPal Pay in 3, and Laybuy, among others. They’re embedded into the checkout flows of major retailers including ASOS, Currys, and many fashion and beauty shops, making them very easy to use without fully considering the terms.
