Introduction
The UK checkout experience has moved on from the days of “cards or PayPal” to a much more sophisticated system. Today, consumers demand flexibility, value, and payment options that meet their spending requirements. Instalments, BNPL, and retail finance have become the norm.
For UK retailers, offering the right mix of payment methods in 2026 isn’t just convenient, it’s a sound commercial strategic move to boost conversion, reduce declined sales, and meet customer expectations.
This article outlines the payment methods UK retailers should offer to deliver the flexibility and meet the demands of their customers.
Why Payment Method Choice Is Now a Revenue Decision
Payment method availability directly impacts sales performance. The absence of a preferred payment option can lead to a higher rate of cart abandonment. Research by the Baymard Institute shows that the rate of checkout abandonment can be as high as up to 69%, with the absence of preferred payment options being a significant factor.
This is particularly relevant for higher-value transactions, where credit or installment payment options are often essential. By offering the right combination of payment methods, merchants can increase conversion rates, improve average order value (AOV), and reduce lost revenue due to declined payments.
Core Payment Methods Every UK Retailer Still Needs
Debit Cards
Debit cards continue to be the driving force behind consumer spending in the UK , with 2.3 billion debit card transactions in October 2025, accounting for £67.1 billion in spend. They are essential for a seamless checkout experience providing familiarity and trust.
Credit Cards
As per UK Finance – Payments and card usage data, credit cards are used extensively for larger transactions, with 403 million transactions in October 2025 (£22 billion spent), and balances rising 8.1% year-on-year. Credit cards are designed for consumers who use existing credit or reward programs.
Digital Wallets (Apple Pay & Google Pay)
Mobile-first shopping is rising. Digital wallets such as Apple Pay and Google Pay remove barriers, allowing one-tap payments from smartphones and tablets. Contactless payments accounted for 66% of credit card and 76% of debit card transactions in October 2025, highlighting the increasing desire for quick and easy payments.
Flexible Payment Methods: BNPL and Instalments
Why Instalment Payments Are Now a Checkout Expectation
Instalment payment options are no longer alternative credit solutions, they have become mainstream payment options that UK consumers now expect to see at checkout. Shoppers across all demographics want the ability to spread the cost of their purchases, and providing this flexibility directly addresses their needs.
BNPL Strengths and Limitations
Buy Now, Pay Later (BNPL) provides interest-free instalments that are attractive to many consumers. However, it often comes with limitations:
- Basket value caps
- Short repayment terms
By positioning BNPL and instalments as a mainstream payment method, retailers can address the changing needs of consumers while retaining control over risk.
Retail Finance as a Checkout Payment Method
When Customers Need More Than BNPL
Some customers require longer-term solutions, particularly for high-value purchases.
Retail finance offers:
- Higher basket value support
- Predictable monthly payments
- Flexible repayment terms
Regulated Retail Finance at Checkout
UK-regulated retail finance comes with fixed-term credit agreements, clear affordability assessments,and consumer protection in line with FCA guidelines. With BNPL soon to fall under FCA regulation in 2026, borrowers will also benefit from:
- Affordability checks to ensure repayment capability
- Clearer communication and disclosures
By offering regulated retail finance at checkout, retailers can responsibly serve a wider range of customers while helping them manage repayments safely.
Second-Line Retail Finance: Recovering Lost Sales
What Is Second-Line Retail Finance?
Second-line retail finance is a backup credit option offered at checkout when a customer’s application is declined by the primary retail finance provider. Rather than losing the sale, retailers can offer a second-line finance option that re-evaluates the customer using alternative lending criteria and more comprehensive affordability assessments.
Why Second-Line Finance Matters for Conversion
Offering a second‑line finance option at checkout helps retailers:
- Reduce hard declines — Customers who would have been rejected are given a second chance to access credit..
- Improve approval rates — Alternative lending criteria mean more customers are eligible for credit.
- Recover lost revenue — Sales that might have been abandoned due to a declined application can now be completed.
How to Build the Right Payment Method Mix for Your Business
To create the ideal checkout experience, retailers should consider:
- Customer demographics and credit profiles – Younger consumers may prefer BNPL, while older consumers may prefer credit cards.
- Average order value (AOV) – Low-value items are usually paid for by debit, credit, or digital wallets, while high-value items use installments, BNPL, or regulated retail finance.
- Product category and purchase frequency – By offering a variety of payment options such as BNPL, Instalments, and Second-Line Finance, more consumers can pay for their purchases, and conversion rates typically improved.
According to ONS data for Q3 2025 household spending is still growing, up 0.3% quarter-on-quarter and 0.7% year-on-year. The biggest areas of spending are clothing, footwear, and food and drink, emphasising the need for flexible payment options for everyday, mid-value purchases
