Compare the best UK payment gateways for WooCommerce in 2026. Fees, SCA compliance, and key features to boost sales.
Why UK-Specific Payment Gateways Matter for WooCommerce
Running a WooCommerce store in the UK means dealing with unique requirements. Strong Customer Authentication (SCA) is mandatory for most online payments, and your gateway must handle 3D Secure 2 seamlessly. Also, customers expect to pay in GBP without hidden currency conversion fees. A UK payment gateway like Stripe, PayPal, or Sage Pay ensures compliance and a smooth checkout experience. Moreover, UK shoppers increasingly favour digital wallets like Apple Pay and Google Pay, as well as Buy Now Pay Later (BNPL) options like Klarna. Choosing a gateway that supports these methods can reduce cart abandonment and boost conversion rates. This guide breaks down the top choices, their fees, and their suitability for British ecommerce.
Top WooCommerce Payment Gateways for the UK Market
Stripe is the most popular choice for UK stores due to its ease of integration and transparent pricing – 1.5% + 20p per transaction for UK cards. PayPal is also widely used, with fees around 2.9% + 30p for standard payments, but it offers buyer protection that can increase trust. For UK-specific banks, Sage Pay (now Opayo) integrates well with major acquirers like Barclaycard and Worldpay, and it supports direct debits. Klarna is a great addition for BNPL, especially for fashion and high-ticket items. Other notable mentions include Adyen (for larger enterprises) and Mollie, which has become popular for its simple fee structure and strong UK support.
Comparing Fees, Setup Costs, and Currency Support
When comparing UK payment gateways, look beyond the per-transaction fee. Some providers charge monthly fees, setup fees, and additional costs for chargebacks or international cards. Stripe has no setup or monthly fees, and its standard rate covers all major debit and credit cards. PayPal’s fees are slightly higher but include seller protection. Sage Pay charges a monthly subscription starting around £20, but it can offer lower transaction rates if you negotiate based on volume. Also check whether the gateway supports multi-currency to sell to international customers. Most UK gateways charge around 1% for currency conversion. For new stores, zero-monthly-fee options like Stripe or Mollie are often most cost-effective.
Staying Compliant: SCA, GDPR, and PCI DSS in the UK
Since 14 September 2021, Strong Customer Authentication (SCA) is fully enforced in the UK for most online payments. Your gateway must be able to dynamically challenge customers with 3D Secure 2 when needed, without creating unnecessary friction. Additionally, being GDPR-compliant means your payment data handling must be transparent and secure. Leading gateways like Stripe and PayPal are fully PCI DSS compliant and shift the security burden away from you. They also offer tools for data retention and customer consent. When selecting a gateway, ensure it provides clear documentation on how it processes personal data, including storing transaction histories and handling subject access requests. This protects both you and your customers.
How to Choose the Right Gateway for Your WooCommerce Store
Start by analysing your typical order value and customer demographics. If you sell low-cost items, a flat-rate gateway like Stripe will keep fees down. For high-ticket products, consider a gateway with lower percentage fees and support for BNPL like Klarna. Test the payment flow on mobile – many UK customers shop on their phones. Also, think about international sales: does the gateway support popular payment methods in other countries? Finally, check the WooCommerce plugin compatibility. Most major gateways offer official plugins, but third-party solutions can be less reliable. Read reviews and test with sandbox mode before going live. The right choice balances cost, customer experience, and compliance.
FAQ
Stripe and Mollie are typically the cheapest for new stores because they have no monthly fees and charge a simple per-transaction rate (around 1.5% + 20p for UK cards). PayPal is slightly more expensive but offers strong buyer protection. If you have high volume, negotiated rates with Sage Pay by Worldpay might beat these.
