Key Payment Methods in the United Kingdom

1. Digital Wallets

Digital wallets have become the preferred online payment method for many UK shoppers. Apple Pay, Google Pay, and PayPal provide rapid checkout solutions, especially on mobile. PayPal remains widely used for e-commerce transactions on desktop, while Apple Pay and Google Pay have become standard options at both online and in-store checkout. For merchants operating in the UK, offering digital wallets at checkout consistently improves conversion rates, particularly for first-time buyers who prefer not to enter card details on unfamiliar sites. The UK has high smartphone penetration and contactless-readiness, making digital wallets one of the fastest-growing alternative payment methods UK-wide.

2. Open Banking and Faster Payments

The UK's Open Banking standards, combined with the Faster Payments infrastructure, allow for instant, direct bank-to-bank checkout. Merchants can request payments that consumers authenticate via their retail banking app. This provides immediate authorization, lower transaction fees than cards, and eliminates chargebacks entirely.

Open Banking payments in the UK are regulated by the Financial Conduct Authority (FCA) and operate through the Open Banking Implementation Entity (OBIE).^[1] Payment providers use APIs to initiate transactions directly from the consumer's bank account, routing through Faster Payments for near-instant settlement. For UK merchants evaluating alternative payment methods, Open Banking and Pay by Bank represent the lowest-cost option with the highest authorization rates. The infrastructure also supports recurring payments via variable direct debits, making it viable for subscriptions in addition to one-time checkout.

BACS Direct Credit and CHAPS remain relevant for high-value B2B and payroll transfers, though they are less common in consumer checkout. For most UK merchant use cases, Faster Payments is the primary bank-to-bank rail.

3. Buy Now, Pay Later (BNPL)

BNPL has achieved significant penetration in the UK. Services like Klarna, Clearpay (Afterpay's UK brand), Laybuy, and Zilch are highly popular in fashion, retail, and lifestyle sectors. The UK BNPL market is one of the largest in Europe by transaction volume, driven by younger consumers who prefer installment payments over credit cards. The Financial Conduct Authority has signaled incoming regulation for UK BNPL providers,^[2] which is expected to formalize consumer protections while preserving market access for established providers.

For UK merchants evaluating alternative payment methods for their checkout, BNPL typically increases average order value and conversion rates, though the merchant fees are higher than card processing. Sign up for Klarna →

Direct Debit remains one of the most widely used payment methods in the UK for utilities, subscriptions, and insurance. The UK's Direct Debit guarantee provides strong consumer protection, and integration is straightforward for most payment providers.
