UK online retail sales reached £127.4 billion in 2024, a 3.4 percent increase from 2023, according to ONS data analyzed by Retail Gazette. Card payments still anchor most checkouts, while Open Banking is gaining ground: by March 2025 the UK processed 27 million Open Banking payments in a single month, with merchant discount rates as low as 0.3 percent according to UK Finance.
For UK merchants, choosing the right payment gateway shapes checkout conversion, chargeback handling, and the ability to process EU card transactions cleanly after Brexit. Any gateway operating here must hold an FCA Authorised Payment Institution (API) or Electronic Money Institution (EMI) licence and support PSD2 Strong Customer Authentication. This guide reviews six leading payment gateways for 2026, including a global crypto option.

Stripe
来源: Stripe
Stripe is the dominant payment gateway for UK tech businesses and is the default choice for developers, thanks to its API quality, detailed documentation, and broad product range. It covers one-time payments, subscriptions (Stripe Billing), marketplaces (Stripe Connect), fraud detection (Radar), and complex subscription logic. Stripe is PSD2 SCA compliant and handles the 3D Secure flow automatically.
For UK cards, the fee is 1.5 percent plus 20p per transaction; European cards attract 2.5 percent plus 20p. Settlement is typically 7 days initially, dropping to 2 days for established accounts. The platform supports 135-plus currencies and 40-plus payment methods, which makes it the default for UK businesses with international ambitions.

贝宝
来源: 贝宝
PayPal remains one of the most recognized payment brands in the UK and is trusted by consumers for its buyer protection policies. For merchants, PayPal offers two main products: PayPal Checkout (the button-based integration) and Braintree (the API-first payment platform). Standard PayPal fees are higher than Stripe, but the brand recognition lifts checkout conversion, particularly with older demographics.
PayPal processes payments in 25-plus currencies and operates a BNPL product (Pay in 3) that has gained UK traction as a no-cost installment option. The main downside is that PayPal can hold funds during disputes, which creates cash flow complications for smaller businesses.

- 月租费： None for standard; optional extras
- 支持的货币： GBP plus 25 international currencies
- 关键特点： Consumer trust, buyer protection, and Pay in 3 BNPL
WorldPay的
Worldpay is the UK’s largest payment processor by volume and handles a significant share of UK card transactions through its acquiring network. It serves major retailers, airlines, utilities, and financial services firms. Worldpay offers both online gateway services and physical terminal solutions, and following its acquisition by FIS and subsequent independent spin-off, it continues to serve enterprise accounts with custom pricing and dedicated relationship management.
For large UK businesses processing millions of pounds monthly, Worldpay’s acquiring relationships with major UK banks and its established dispute resolution process provide stability at scale. Smaller businesses rarely secure competitive rates without significant volume.

- 关键特点： UK’s largest processor with enterprise scale across POS and online
Opayo (formerly Sage Pay)
Opayo, formerly Sage Pay, is a long-established UK payment gateway with a strong reputation among accountants and finance professionals. Its deep integration with Sage accounting software makes it the default choice for businesses already running Sage 50 or Sage 200.
Opayo offers a straightforward hosted payment page, a phone payment solution for call centres, and a virtual terminal for mail-order businesses. The monthly subscription pricing model gives predictable costs for businesses with consistent transaction volumes. Its fraud screening tools are well-regarded in the UK SME market.

广场
Square entered the UK market in 2017 and has grown steadily among small businesses, cafes, market traders, and service providers. Its free card reader offers a simple entry point, and the Square POS app handles sales tracking, inventory, and reporting. Online, Square integrates with websites and offers payment links and a virtual terminal.
The flat-rate pricing of 1.75 percent for card-present transactions and 2.5 percent for online transactions is easy to predict. Square’s ecosystem also includes a business bank account, payroll tools, and appointment booking. For small UK businesses that want an integrated POS and online payment solution without monthly fees, Square is a strong contender.

Upay is a crypto card and wallet platform that lets UK users hold BTC, ETH, USDT, USDC, and other major cryptocurrencies and spend them anywhere Visa is accepted. UK mainstream payment gateways do not process crypto as a direct payment method, which leaves a gap for anyone earning, holding, or paying in digital assets.
The Upay Visa card covers 55 million-plus merchants worldwide, supports ATM withdrawals, and integrates with Apple Pay and Google Pay, both heavily used in the UK. For UK freelancers paid in USDT, crypto investors who want to spend without selling, or businesses accepting crypto from international clients, Upay is the practical option. Available on iOS and Android at upay.best.

How to Choose the Right Payment Gateway for Your Business in the United Kingdom
UK businesses should first confirm that any payment gateway they use is FCA-authorised as an Authorised Payment Institution or Electronic Money Institution. PSD2 Strong Customer Authentication is legally required for card-not-present transactions in the UK, so check that the gateway handles the SCA flow automatically rather than leaving it to your engineering team to implement.
For businesses with European customers, verify that the gateway has a separate EU entity so EU card transactions clear at the better intra-EEA interchange rates rather than the higher post-Brexit international rates. Compare total cost of ownership, not just headline fees: monthly fees, chargeback fees, refund fees, and currency conversion margins all add up. Developer resources, uptime SLAs, and the quality of dispute management matter just as much as the transaction percentage on the marketing page.
Why Upay is a Strong Choice in the United Kingdom for 2026
The UK’s Financial Conduct Authority has established clear guidance on cryptoasset businesses, and several major crypto firms are FCA-registered and operating legally in the UK. Mainstream UK payment gateways, though, do not accept crypto as a direct payment method, which leaves a gap for the growing number of UK consumers and businesses that hold digital assets.
Upay closes that gap. As a crypto card and wallet platform, it lets UK users hold BTC, ETH, USDT, USDC, and other major cryptocurrencies and spend them at any Visa merchant, covering more than 55 million merchants worldwide. For UK freelancers paid in USDT, crypto investors who want to spend without selling first, or businesses accepting crypto from international clients, Upay provides a practical solution. The card works at UK supermarkets, online retailers, and travel merchants, and integrates with Apple Pay and Google Pay. ATM withdrawals are supported. Available on iOS and Android at upay.best.
结语
The UK payment gateway market is well-served by global and local options. Stripe leads for developers and international businesses. PayPal remains strong for consumer trust. Worldpay and Opayo serve enterprise and accountancy-focused businesses. Square fits small physical retail. For crypto payments in the UK’s increasingly crypto-aware market, Upay provides a Visa-powered card that works anywhere. Get started at upay.best.
常见问题解答 (FAQs)
What is the cheapest payment gateway in the UK?
Stripe charges 1.5 percent plus 20p for UK cards with no monthly fee, which is among the lowest-cost options for businesses with variable transaction volumes. Square’s flat 1.75 percent rate suits physical retail.
Do UK payment gateways comply with PSD2 and SCA?
Yes. All major UK gateways, including Stripe, PayPal, Worldpay, and Opayo, support PSD2 Strong Customer Authentication. Stripe handles the SCA flow automatically without merchant intervention.
Can UK businesses accept crypto payments?
Standard UK gateways do not support crypto. Upay lets businesses and individuals spend BTC, ETH, USDT, and USDC via a Visa card at any merchant without converting to GBP.
Does Brexit affect payment gateway choices for UK businesses?
Post-Brexit, UK acquirers lost EU passporting, which means some EU card transactions now incur higher interchange fees. Stripe, PayPal, and Worldpay all maintain EU entities that handle EU card transactions at the better intra-EEA rates.
How does Open Banking affect payment gateways in the UK?
Open Banking lets payments initiate directly from a bank account without a card, with merchant fees as low as 0.3 percent and no chargeback risk. Several UK gateways now offer Open Banking as an alternative payment method alongside cards.
Can I use Upay alongside a UK payment gateway?
Yes. Many UK businesses run Stripe or Worldpay for GBP card payments and add Upay for crypto income, international spending, or personal use. The two operate independently.
