WooCommerce Payment Gateway Comparison for UK Businesses (2026)

A WooCommerce payment gateway is the service that lets your UK online store accept card, digital wallet, and alternative payments securely at checkout. Choosing the right one for your business is both a technical and financial decision, because it directly affects conversion rates, cash flow, and customer trust.

• Stripe typically charges 1.5% plus 20p for UK-issued cards, with no monthly fee for standard accounts.
• PayPal's standard UK transaction rate is approximately 2.9% plus 30p.
• GoCardless charges around 1% per Direct Debit transaction, with a small cap, making it cheaper than card processing for subscriptions.
• The UK's Strong Customer Authentication rules require most online payments to be verified with additional authentication factors.

Why Your Gateway Choice Matters for UK WooCommerce Stores

Your payment gateway shapes your transaction costs, checkout completion rate, and compliance with UK financial regulations, so it deserves careful thought.

Choosing a gateway is not just about accepting cards. It affects the fees you pay, the payment methods your customers see, and the speed of your settlements. In the UK, Strong Customer Authentication (SCA) also means most online payments need extra verification, and not every gateway handles this with the same level of friction.

A poor choice can lead to abandoned carts and hidden charges. On the other hand, a well-integrated gateway, such as WooCommerce Payments or Stripe, can improve conversion while keeping compliance simple. For British shoppers, familiar brand names like PayPal and Klarna matter too, because customers often prefer a checkout they already trust.

Retailers also need to think about recurring payments and refunds. Subscriptions, wholesalers, and service businesses may need Direct Debit or tokenised card storage. These factors, alongside monthly costs, should form part of your decision.

Key Features to Compare Between Gateways

Compare fee structures, settlement times, recurring billing support, SCA readiness, and the payment methods each gateway supports for UK customers.

Start with the total cost per transaction. UK card fees usually combine a percentage with a fixed pence amount. Look beyond the headline rate to international cards, refunds, chargebacks, and payout fees. Some gateways charge monthly subscription fees, while others make money only on successful orders.

Next, check which payment methods are covered. A good UK gateway should support Visa, Mastercard, Amex, Apple Pay, Google Pay, and often PayPal at the same checkout. Buy-now-pay-later services like Klarna are increasingly popular because they increase average order values.

Recurring billing is another key area. If you sell subscriptions, you need a gateway that stores cards safely and supports automated renewals. Direct Debit through GoCardless is a useful option for B2B and membership sites. Settlement speed also matters, as some processors pay out within one day, while others wait up to a week.

• Check the percentage rate and fixed fee for UK cards.
• Review international card fees if you sell to the EU.
• Confirm Apple Pay, Google Pay, and PayPal support.
• Ask about recurring payments and Direct Debit.
• Test the mobile checkout experience before launch.

Stripe vs PayPal vs Square for UK Retailers

Stripe offers the most flexible developer experience, PayPal builds buyer trust, and Square is a strong all-rounder for retail-led stores.

Stripe is the foundation for WooCommerce Payments and is widely used by UK developers. It typically charges 1.5% plus 20p for UK-issued cards, and it supports Apple Pay, Google Pay, and Klarna through plugins. Stripe also handles SCA well, with minimal customer friction, and offers advanced reporting and subscription billing.

PayPal is a checkout option that many British shoppers already trust. Its standard UK rate is around 2.9% plus 30p. Integrating PayPal with WooCommerce is quick, and you get both a card payment option and a PayPal button. The downside is that some customers leave your site to approve payment, which can reduce completion rates.

Square is a good fit if you also sell in person. Its standard online rate is around 1.75% per transaction, and it integrates with WooCommerce via an official extension. Square offers a unified dashboard for online, mobile, and brick-and-mortar payments, though its advanced e-commerce features are less flexible than Stripe's.

Alternative Gateways and Buy-Now-Pay-Later Options

Klarna appeals to buy-now-pay-later shoppers, Amazon Pay uses existing customer accounts, and GoCardless handles Direct Debit subscriptions efficiently.

Klarna is one of the most popular payment methods in the UK. It splits payments into three or more interest-free instalments, which helps increase conversion for high-ticket items. WooCommerce merchants can add Klarna through official plugins, and UK shoppers often choose it at checkout when they trust the brand.

Amazon Pay lets shoppers pay using the address and card details stored in their Amazon account. This reduces checkout friction, especially for customers who already use Amazon. Fees are transaction-based, and the gateway supports strong customer authentication, making it a viable alternative for established UK merchants.

GoCardless is not a card processor. It connects to a customer's bank account and collects payments by Direct Debit. Fees are lower than cards, typically 1% per transaction with a cap. It is an excellent choice for subscription boxes, gyms, and software businesses operating in the UK.

How to Choose the Right Gateway for Your WooCommerce Store

The right gateway depends on your order value, customer base, subscription model, and whether you need in-person payments as well as online.

Begin by listing your product types and typical order values. A store selling high-cost furniture will benefit from Klarna or financing options, while a low-margin business needs the lowest possible card fee. Consider whether your customers buy once or subscribe for a service, because recurring billing changes your gateway needs.

Evaluate your target audience in the UK. If your customers are older and conservative, they may prefer PayPal because they recognise it. If they are younger and mobile-first, Apple Pay and Google Pay should be prominent. Test the checkout with real users to see where hesitation occurs.

Also think about your business logistics. Do you need to accept payments at a market stall or pop-up shop? If so, seek a provider like Square that offers both online and in-person payments. Finally, plan for growth. A flexible API, good reporting, and easy migration are important if you expect to scale. If you need help managing your store, check WpAsis's WordPress services.

Next Steps: Setup and Expert Support

Once you have selected a gateway, you can install the plugin, connect your merchant account, test sandbox mode, and get professional support to keep checkout performance healthy.

After choosing a gateway, install the relevant plugin from the WooCommerce marketplace. For example, WooCommerce Payments will use a Stripe account, while PayPal and Klarna have official extensions. Configure webhooks so that order statuses update automatically, and test refunds and subscriptions in sandbox mode before going live.

Security remains the priority. Use HTTPS, keep WordPress and plugins updated, and monitor for failed payment recovery. Many UK merchants use automatic retries to capture payments after cardholders retry or change their payment method. This type of task requires ongoing attention rather than a set-and-forget approach.

If you would rather focus on your products, professional support can manage maintenance, updates, and speed checks. For example, WpAsis provides WordPress care plan pricing that helps UK businesses keep their stores secure. You can also review WordPress maintenance packages for small businesses in the UK if you need a broader plan.
