💳 Klarna, Buy Now Pay Later and mortgages – could the way you pay for everyday purchases affect your mortgage application?
If you’re hoping to buy your first home, move house or remortgage, there’s an area of your finances that’s becoming increasingly important to think about: Buy Now, Pay Later.
Services such as Klarna have completely changed the way we pay for things online.
Rather than paying £150 today, you might be offered the opportunity to split it into three payments of £50.
For many people, it’s convenient and manageable.
But we’ve reached the point where short-term payment options can be available on increasingly small, everyday purchases.
And if you’re planning on applying for a mortgage, it’s worth thinking about what that says about your finances.
What’s changing?
Buy Now, Pay Later is moving into a much more regulated environment in the UK, with greater consumer protection and affordability requirements being introduced.
The important point for mortgage customers, however, is slightly different.
Mortgage lenders want to understand how you manage your money and whether the mortgage you’re applying for is genuinely affordable.
They may look at your income and expenditure, credit commitments, credit history and, depending on the lender and application, your bank statements.
So where does Buy Now, Pay Later fit into this?
Does using Klarna mean you can’t get a mortgage?
Absolutely not.
Using Klarna, PayPal Credit or another form of short-term borrowing doesn’t automatically stop you getting a mortgage.
Context matters.
Someone occasionally using a payment facility and comfortably managing their finances is very different from someone with multiple agreements who appears to be regularly relying on credit to fund everyday spending.
A lender is ultimately trying to answer a simple question:
Does this customer appear able to comfortably afford the mortgage they’re asking us for?
Why small payments can still matter
One £30 monthly commitment probably doesn’t sound particularly significant.
But add together:
💳 Several Buy Now, Pay Later agreements
🚗 Car finance
💰 Personal loans
💳 Credit card balances
📱 Other regular commitments
…and suddenly the overall picture can look quite different.
That’s particularly important if you’re already close to the maximum amount a lender is prepared to offer you.
So what should you do before applying for a mortgage?
If you’re hoping to apply for a mortgage in the coming months, it’s worth being deliberate about taking on new borrowing.
That doesn’t mean you need to stop using credit completely.
But before clicking “Pay in 3”, ask yourself:
Do I actually need to borrow this money?
If the answer is no and you’re preparing for a mortgage application, paying for it outright may leave your finances looking simpler.
Most importantly, don’t panic if you’ve already got Klarna or Buy Now, Pay Later agreements.
Every mortgage lender assesses applications differently, and having these commitments doesn’t automatically mean there is a problem.
🏡 If you’re considering buying, moving or remortgaging, speak to a mortgage adviser early.
We can look at your income, commitments and overall circumstances and help you understand how a mortgage lender is likely to view your finances before an application is submitted.
Sometimes getting mortgage-ready isn’t about making huge changes.
It’s about making lots of sensible little decisions in the months before you apply.
