Three months ago, on 15 July 2026, Buy Now Pay Later in the UK stopped being a grey zone. Interest-free instalment plans from third-party lenders became regulated consumer credit, supervised by the Financial Conduct Authority. For merchants, the Buy Now Pay Later button at checkout looks the same. Almost everything behind those payments has changed.
I’m Vladyslav Kolodistyi, and I spend a lot of time on how people make payments online. BNPL is one of the most interesting payments stories of the last decade. It grew from a niche fashion checkout option into a mainstream way to split payments for almost anything. Now it has to behave like the consumer credit product it always was.
In one sentence from Vladyslav Kolodistyi: BNPL regulation protects shoppers and rewards merchants who treat Buy Now Pay Later as consumer credit rather than as a free conversion trick.
The scale of these payments explains why the FCA acted. Its own Financial Lives research on deferred payment credit found that about one in five UK adults, some 10.9 million people, used BNPL in the year to May 2024. The FCA puts the market at over £13 billion of lending in 2024, up from just £0.06 billion in 2017.
“A payments product used by one in five adults cannot stay outside the rules. BNPL regulation was a question of when, not if.”
Vladyslav Kolodistyi
The next test comes from buyers that are not people at all. AI agents already complete purchases on a shopper’s behalf, yet regulated consumer credit still needs a human who saw the terms and a stored record of that consent. I explored this mandate problem with The AI Journal in a piece on agentic commerce and the checkout built for AI agents. BNPL providers that solve consent for agents early will keep their place in the checkouts that follow.
What BNPL regulation changes in practice
The FCA calls Buy Now Pay Later deferred payment credit. It covers interest-free plans repaid in twelve or fewer instalment payments within twelve months. From Regulation Day, the lenders that offer it need FCA authorisation or a place in the temporary permissions regime.
Three changes matter most for merchants that take BNPL payments. First, lenders must run proportionate affordability checks before they lend. Second, customers get clear information upfront about payments due, dates and what happens if they miss one. Third, shoppers can take complaints to the Financial Ombudsman Service and gain protection on purchases between £100 and £30,000, much like other consumer credit.
The road to UK BNPL regulation, from consultation to full authorisation. Timeline by Vladyslav Kolodistyi.
One nuance of BNPL regulation surprises many merchants. BNPL plans that a retailer offers directly, without a third-party lender, stay exempt. Most merchants use a BNPL provider, so the rules reach them through that partner. The contract, the checkout wording and the customer journey all now sit inside a regulated consumer credit process.
“Merchants do not hold the licence, but they own the checkout. In a regulated world, the checkout is where compliance becomes visible.”
Vladyslav Kolodistyi
BNPL rarely replaces other payments entirely. In the checkouts I review, it sits next to card payments, wallet payments and open banking payments. Each option serves a different shopper. Regulation brings Buy Now Pay Later closer to the other payments on that list in one respect: every method now comes with clear consumer rights. That parity makes it easier to design a checkout where shoppers pick the payments method that suits them, not the one with the loudest marketing.
What changes for merchants that offer Buy Now Pay Later at checkout. Summary by Vladyslav Kolodistyi.
| Area | Before 15 July 2026 | After 15 July 2026 |
| Lender status | Unregulated for interest-free plans | FCA authorised or in the temporary regime |
| Approval at checkout | Light checks, near-instant yes | Proportionate affordability checks |
| Customer information | Varied by provider | Clear upfront terms on payments and missed payments |
| Complaints | Handled by the provider only | Access to the Financial Ombudsman Service |
| Merchant exposure | Mainly commercial | Checkout wording and promotions under scrutiny |
Buy Now Pay Later and conversion after the rules
The obvious fear among merchants is lower approval rates and lost payments. When a lender checks affordability, some shoppers who used to get an instant yes will now get a no. I expect a small dip in BNPL acceptance, especially for younger customers with thin credit files. For most merchants, the effect on overall payments volume will be modest, because declined shoppers often switch to card payments or wallets.
The more important shift is in quality. Buy Now Pay Later customers who pass an affordability check are less likely to default, return goods in frustration or file disputes. Lenders carry less bad debt and can keep merchant fees on BNPL payments stable. A healthier consumer credit book is good for everyone in the payments chain.
“A slightly lower approval rate on healthier customers beats a high approval rate that ends in arrears, complaints and churn.”
Vladyslav Kolodistyi
Marketing needs attention too. Phrases like “free money” or “no strings” now invite scrutiny under consumer credit promotion rules and the Consumer Duty. I advise merchants to describe BNPL plainly: what it is, how the payments work and what happens if a customer misses one. Train customer service teams as well. They should know how the instalment payments work, where to send a shopper in difficulty and which promises they must never make.
Who carries the risk now
In most Buy Now Pay Later models, the lender settles the merchant upfront, minus a fee, and then collects the instalment payments from the shopper. The merchant receives its payments on day one. The lender carries the risk when shoppers miss payments. That structure made BNPL attractive to merchants, and the new rules leave it intact.
What changes is the cost of that risk. Affordability checks, arrears handling and FCA supervision of consumer credit cost money. Some providers will raise merchant fees or tighten limits. Others will compete on lower arrears and faster settlement of payments. Over time, I expect merchant fees on Buy Now Pay Later to move closer to what merchants pay for card payments.
“Regulation did not move the credit risk to merchants. It moved the cost of doing consumer credit properly into the price of BNPL payments.”
Vladyslav Kolodistyi
Credit files and the shopper
Shoppers feel the change most in their credit files. Lenders now look at credit history before they approve BNPL payments, and missed payments can affect a customer’s credit score. For many young shoppers, Buy Now Pay Later was their first consumer credit product. Handled well, it can build a positive record. Handled carelessly, it can damage one.
Merchants should care about this, because trust drives repeat payments. A customer who feels trapped by instalment payments blames the shop as much as the lender. Clear terms and fair support protect the brand long after the order ships.
Buy Now Pay Later beyond retail
The regulation lands as Buy Now Pay Later spreads into new sectors. Travel firms use it to spread holiday payments. B2B payments platforms offer pay-later terms to small businesses buying stock. Those business plans fall outside consumer credit rules, but the consumer market sets expectations. Buyers now expect clear payments schedules and fair treatment when payments slip.
For merchants, this means Buy Now Pay Later is no longer a marketing add-on. It sits in the payments strategy alongside cards, open banking and wallets. Each method has a cost, a conversion effect and a risk profile. BNPL regulation simply makes those trade-offs easier to compare.
What I would ask your BNPL provider this month
Merchant checklist by Vladyslav Kolodistyi. If you offer Buy Now Pay Later at checkout, these are the questions I would put to your provider now:
- Is your firm fully authorised, or still in the temporary permissions regime, and when does your application close?
- How do your affordability checks affect approval rates for my customer base and my payments volume?
- Which checkout wording and promotional claims have you approved for BNPL regulation?
- How do you handle customers in financial difficulty, and what will they see from my brand?
- What reporting will I get on declines, arrears and complaints linked to my payments?
The answers tell you whether your partner treats regulation as a box to tick or as part of its product. That difference will show up in your payments data within a few quarters.
“Choose a BNPL partner the way you would choose a bank: for how it behaves on a bad day, not for how fast it says yes.”
