What this choice actually costs you
What actually switched on 15 July 2026
For a decade, UK buy-now-pay-later lived in a legal gap: interest-free credit under 12 months was exempt from the Consumer Credit Act, so Klarna, Clearpay and PayPal Pay in 3 operated outside FCA rules that bound every credit card. The Treasury closed that gap by creating a new regulated category — Deferred Payment Credit, with FCA authorisation mandatory from 15 July 2026.
Five protections arrived at once: FCA authorisation of providers, mandatory affordability checks before lending, Consumer Duty obligations (including forbearance when you're struggling), Section 75 joint liability on qualifying purchases, and free escalation to the Financial Ombudsman when a provider's answer doesn't satisfy you.
None of it is retroactive. An agreement from June 2026 keeps its old terms, no FOS, no Section 75, until it is paid off. If you carry balances from both eras, you hold two different legal products that happen to share an app.
The £600 sofa test: merchant collapse, before and after
Ellie orders a £600 sofa on Pay-in-3 and the retailer goes into administration before delivery. Under the old regime she was an unsecured creditor of a dead company: instalments still owed, sofa never coming, recovery odds near zero. That exact scenario filled complaint forums for years.
Under DPC, Section 75 of the Consumer Credit Act applies: for single items priced £100 to £30,000, the lender is jointly and severally liable with the merchant. Ellie claims against her BNPL provider, the outstanding instalments are cancelled, and paid ones are refunded. If the provider stalls past eight weeks or rejects unfairly, the Financial Ombudsman takes the case free of charge.
Mind the threshold mechanics: it is the single item's price that counts. A £600 sofa qualifies; a £120 basket of three £40 cushions does not. For purchases under £100, your route is the provider's own refund process: improved by Consumer Duty, but not statutory.
The bill for all this: your credit file now remembers
The old regime's dirty secret was invisibility: most BNPL activity never reached the credit bureaus, so neither did most missed payments. Regulation ends that both ways: DPC providers report payment history to Experian, Equifax and TransUnion, and an instalment 30+ days late lands on your file as a delinquency, visible to every mortgage and loan underwriter for six years.
Scale that against the money: on a £500 order, Klarna's late fees cap at £10 in total. The fee is trivial; the file entry is not. A £10 slip on trainers in 2026 can still be sitting in your mortgage application in 2032: a wildly asymmetric penalty that did not exist eighteen months ago.
Three habits fit the new rules: set autopay for every plan, since the downside moved from fees to file damage; keep paying instalments during a goods dispute and reclaim afterward, because stopping payment mid-dispute now marks your file; and if money is genuinely tight, tell the provider — Consumer Duty forbearance pauses fees and adverse reporting, but only once you ask.
One more shift worth watching at the checkout itself: affordability checks mean declines now happen. Providers must assess whether you can afford the instalments across all your visible credit, so stacking plans across Klarna, Clearpay and PayPal simultaneously, the classic pre-2026 pattern, will increasingly hit a wall. That is the system working as designed: the FCA's own research found BNPL users were twice as likely to also hold high-cost credit, and the checks exist to interrupt exactly that spiral before it compounds.
