Buy now pay later in the UK has changed. Since 15 July 2026, the Financial Conduct Authority has regulated the most common type of BNPL for the first time. That means new protections for shoppers, but it does not make it free money. Here is how it works now, what has changed and when it can turn into a debt trap.
How Buy Now Pay Later Works in the UK
Buy now pay later lets you split a purchase into a few interest free payments. Klarna, Clearpay and PayPal Pay in 3 are the best known names. You usually pay the first part at checkout and the rest over the following weeks or months.
As long as you pay on time, you pay no interest. That is the big attraction. However, missing a payment can bring late fees, and some longer plans do charge interest, so always check what you are signing up to.
What Changed for Buy Now Pay Later in July 2026
From 15 July 2026, the FCA began regulating what it calls Deferred Payment Credit. That covers interest free BNPL paid back in 12 or fewer instalments within a year, where the lender is a different company from the shop. According to the FCA, the main changes are:
- Lenders must check you can afford the repayments before you sign up.
- Lenders must tell you the amount, the payment dates, any late fees and your rights before you agree.
- If you miss a payment, the lender must contact you and offer support if you are struggling.
- You can now take complaints to the Financial Ombudsman Service.
There is one catch. Agreements taken out before 15 July 2026 stay unregulated. The rules also do not cover BNPL offered directly by the shop itself.
Why Buy Now Pay Later Can Become a Debt Trap
The danger with BNPL is how easy it feels. There is no big bill at checkout, so it is tempting to spend more than you planned. In other words, it can make an unaffordable purchase feel affordable.
Several Plans at Once
One plan is easy to track. Five plans across three providers, each taking money on different dates, is not. That is where people slip up and miss payments.
Late Fees and Your Credit File
Miss a payment and you may pay a late fee. Some providers also share your repayment history with credit reference agencies, so missed payments could affect your ability to get a mortgage or loan later. My guide to fixing a bad credit score covers how to repair the damage.
Using It for Everyday Spending
If you are using BNPL for food shopping or bills, that is a warning sign. It usually means your budget is under pressure, and splitting payments only pushes the problem into next month.
How to Use Buy Now Pay Later Safely
Step 1: Only Buy What You Could Afford Today
A good rule is simple. If you could not pay for it in full right now, do not split it. BNPL should help with cash flow, not stretch your budget.
Step 2: Stick to One Provider
Keeping all your plans in one app makes it much easier to see what you owe and when.
Step 3: Set Payment Reminders
Turn on notifications and make sure money is in your account a day or two before each payment date.
Step 4: Read the Late Fee Terms
Under the new rules, lenders must tell you the late fee before you agree. Read it, because it can turn a cheap purchase into an expensive one.
Step 5: Build It Into Your Budget
Treat every BNPL payment as a bill in your monthly budget. If you do not have a budget yet, my guide to budgeting basics will help you set one up in an evening.
Buy Now Pay Later vs Credit Cards
Credit cards charge interest if you do not clear the balance, often at high rates. BNPL is usually interest free if you pay on time. However, a credit card used carefully can offer purchase protection and rewards, and paying it off in full each month builds your credit history.
Both can go wrong in the same way, by encouraging spending you cannot afford. If you are already struggling with card balances, my guide to paying off credit card debt is a better place to start than adding more borrowing.
What to Do If You Are Struggling With BNPL Payments
Contact your lender as soon as you think you might miss a payment. Under the new rules, regulated lenders must offer support. You can also get free, confidential help from MoneyHelper, a service the government funds.

My Take on Buy Now Pay Later
The new rules are a welcome change and give shoppers real protection for the first time. Even so, regulation does not stop you overspending. Used occasionally, for things you can afford, BNPL is a handy tool. Used to plug gaps in your budget, it is a fast route into debt.
