Buy Now Pay Later in the UK: Why Millions Are Hooked and What New FCA Rules Mean for You

There is a moment that will be familiar to many UK shoppers. You are at checkout, the total is higher than expected, and a friendly prompt appears offering to split the cost into three easy instalments. It feels painless. It feels manageable. And increasingly, it feels like a habit.

Buy Now Pay Later services have woven themselves into the fabric of everyday British spending with remarkable speed. What began as a niche option for larger purchases has quietly expanded into the weekly shop, the school uniform run, and the emergency home repair. Klarna, Clearpay, Laybuy and their competitors now process billions of pounds worth of transactions every year in the UK, and their user bases have grown fastest precisely during the period when household budgets have come under the most sustained pressure in a generation.

The cost-of-living crisis did not create BNPL, but it almost certainly accelerated its rise to become a mainstream financial tool rather than a fringe convenience. Understanding why that happened, and what the regulatory response now means for ordinary borrowers, is genuinely important for anyone who uses these services or is tempted to start.

The Scale of the Shift

The numbers involved are not trivial. Research from the FCA's own Financial Lives survey found that approximately 27% of UK adults had used a BNPL product in the 12 months prior to the survey, which translates to roughly 14 million people. Importantly, usage is not concentrated among the wealthy. The data consistently shows higher uptake among younger adults, lower-income households, and renters, precisely the groups who have faced the sharpest squeeze on disposable income since 2021.

What has changed in recent years is not simply the number of users but the nature of what they are buying. Early BNPL adoption centred on fashion and electronics, categories where a deliberate, planned purchase might justify splitting a larger sum. Today, the same instalment logic is being applied to groceries, pet food, and utility bills. That shift matters enormously from a financial health perspective, because it suggests a portion of BNPL usage is filling genuine income gaps rather than smoothing the occasional discretionary splurge.

The appeal is understandable. Unlike a credit card, traditional BNPL products charge no interest if you pay on time. Unlike a personal loan, there is no lengthy application process. For someone who needs a washing machine replaced before payday, the friction is minimal and the short-term logic seems sound. The difficulty, as the regulator has noted repeatedly, is that minimal friction cuts both ways. It makes borrowing easy to enter and easy to accumulate without fully registering the financial commitment being made.

Why Regulators Finally Moved

The FCA has been watching BNPL for several years with what might charitably be described as cautious concern. The sector operated in a regulatory gap that left consumers without the protections they would automatically receive when borrowing through a credit card or personal loan. Providers were not required to conduct affordability checks before extending credit. Borrowers had no automatic right to take complaints to the Financial Ombudsman Service. And the stark differences between providers in terms of late payment charges, default handling, and credit reporting created a confusing landscape for anyone trying to make an informed choice.

The 2021 Woolard Review, commissioned by the FCA, was blunt in its assessment. It found that the unregulated BNPL market posed a risk of significant consumer harm, particularly for those who were already financially vulnerable. Parliamentary debate reinforced that concern, with peers and MPs raising specific worries about how instalment credit products interact with wider debt patterns and whether existing consumer protections were adequate for the digital lending environment.

The pace of regulatory change has frustrated consumer advocates, who point out that millions of people were using largely unregulated credit products throughout a period of severe economic stress. However, the machinery has now moved. The government legislated to bring BNPL within the FCA's regulatory perimeter, and the FCA has been developing the specific rules that will govern how these products are offered, marketed, and managed.

What the New Rules Will Actually Mean

The FCA's incoming regulatory framework represents a meaningful shift in the balance of power between BNPL providers and their customers. The changes are not cosmetic adjustments to existing practice. They involve substantive obligations that will alter how these products work in practice.

Affordability assessments are among the most significant incoming requirements. Providers will need to check that a borrower can reasonably afford to repay before approving a transaction, a standard that credit card issuers and traditional lenders have long been required to meet. This is not a minor administrative hurdle. For a sector whose commercial model has partly depended on fast, frictionless approvals, building in genuine creditworthiness checks represents a real change to the customer journey. The FCA has been clear that these assessments must be proportionate but meaningful, as outlined in their framework for protecting BNPL borrowers.

Access to the Financial Ombudsman Service is another significant gain for consumers. At present, if a BNPL provider handles a dispute poorly, a customer has limited formal recourse. Under regulated status, borrowers will be able to escalate unresolved complaints to the Ombudsman, creating an independent check on provider behaviour that currently does not exist for most BNPL products.

Section 75 protection, which gives consumers the right to claim against a credit provider if a purchase goes wrong, will also apply to regulated BNPL agreements in certain circumstances. This brings BNPL closer to the protection framework that credit card users take for granted, and is particularly relevant for purchases of goods or services that might later be disputed.

Building on these structural changes, the FCA has also focused on transparency and marketing standards. The confirmed protections for BNPL borrowers include requirements around how credit agreements are presented, making it harder for providers to obscure the nature of the financial commitment being entered into. Providers will need to make clear that BNPL is a form of credit, that late payments can have consequences, and that the product should be used by those who genuinely intend and are able to repay.

The Risks That Regulation Cannot Fully Solve

Regulation is a powerful tool, but it cannot resolve all of the tensions inherent in how BNPL is currently used. Even with affordability checks in place, the fundamental dynamic of borrowing to cover everyday costs rather than building financial resilience will not disappear because a lender has ticked a compliance box.

Research by Citizens Advice found that one in ten BNPL users had borrowed from a high-cost lender to repay a BNPL debt, creating exactly the kind of debt spiral that consumer advocates have long warned about. The psychological dimension is also worth acknowledging honestly. Splitting a payment into instalments reduces the perceived cost of a purchase in a way that is well documented in behavioural economics. When the mental accounting softens the immediate impact of spending, people can make commitments they would not make if asked to pay the full sum upfront. This is not a failing unique to any particular group of shoppers; it is a consistent pattern in how human beings process financial decisions.

The incoming rules address some of these dynamics by requiring clearer disclosure and affordability checks, but the product design itself, which is engineered to reduce friction and make credit feel invisible, will remain. For shoppers using BNPL regularly, building their own awareness of how these instalment commitments stack up across multiple providers is still essential. Tracking total BNPL commitments alongside other outgoings, rather than treating each transaction as an isolated event, is a practical habit that regulation alone cannot instil.

What the regulatory changes do address is the information asymmetry and the absence of basic consumer rights that have characterised the market until now. That is genuinely valuable. A borrower who understands that BNPL is regulated credit, who has access to an independent complaints process, and who has been subject to at least a basic affordability check is in a meaningfully better position than someone who simply tapped through a checkout screen with no such framework in place.

What to Expect as Regulation Takes Effect

The transition to full FCA regulation will not happen overnight. Providers will need to apply for authorisation, update their systems, and adjust their products to meet the new standards. Some smaller operators may exit the market rather than bear the compliance costs, which could reduce the number of options available to consumers in the short term.

For established providers like Klarna and Clearpay, the direction of travel has been clear for several years, and both have made public statements about supporting the regulatory process. Whether their practices change as substantively as the rules require is something the FCA will need to monitor actively in the months following implementation.

For consumers, the practical advice is straightforward even if it is not always easy to follow. BNPL is a form of credit, and it should be treated as such in personal budgeting. The incoming rules will make it harder for providers to obscure that reality, but the responsibility for managing borrowing sensibly sits partly with the individual. Using BNPL as a short-term cash flow tool for specific, affordable purchases is a very different proposition from accumulating multiple open agreements across different providers to cover regular living costs, and the distinction is worth keeping clearly in mind.

The FCA has signalled that consumer outcomes will be central to how it assesses whether the new framework is working. If affordability checks are being bypassed in practice, or if marketing continues to present BNPL as consequence-free spending, the regulator has made clear it will act. That ongoing oversight, rather than any single rule change, may ultimately be the most important protection of all.
