Cheapest Online Payment Processing UK: Fees and Providers Compared

The cheapest way to take online payments is not always the provider with the lowest percentage fee. A few pennies per transaction can quickly be outweighed by fixed charges, card type, currency conversion, your ecommerce platform and the way your customers prefer to pay.

This guide explains these factors and compares the cheapest online payment processing routes in the UK, including card checkout, payment links, Direct Debit and ecommerce platforms. It also shows how to compare the total cost before you commit.

Cheapest online payment processing at a glance

The best value depends on the payment route, not just the headline rate. Use this as a first filter before checking the provider's live terms.

What makes one online payment processor cheaper than another?

Start with the percentage fee and fixed fee, then check the costs that can make an apparently cheap option more expensive:

• whether the rate applies to UK consumer cards, overseas cards, commercial cards or digital wallets;
• your average transaction value and the number of transactions you expect each month;
• monthly subscription, gateway or platform fees;
• refund, chargeback, payout and currency-conversion charges;
• whether customers need card checkout, a payment link, Direct Debit or an ecommerce-wallet option; and
• the accounting, reporting, fraud-management and checkout features you actually need.

For example, a fixed charge matters more to a business taking many small payments. A higher percentage matters more when average order values are larger. Compare a realistic month of sales rather than one transaction in isolation.

Payment gateway vs payment processor

A payment processor handles the movement and authorisation of a card or bank payment. A payment gateway is the checkout technology that securely passes payment details from your website to that processing route.

Some providers package both together. Others let you use a gateway, an ecommerce platform and a separate processor. That is why a quoted card rate is only one part of the cost of taking payments online: you may also pay for your store platform, gateway or extra features.

Online payment processing fees compared

The table below compares selected published UK rates. These are starting prices, not a quote, and they can change. Check the full rate card before signing up.

A quick cost example

For one £1,000 online transaction on a standard UK consumer card, the published pay-as-you-go rates above would produce these processing charges:

This is an illustration, not a full cost comparison. It excludes VAT, provider-plan costs, different card categories, refunds, disputes, currency conversion and any negotiated rate. Check the exact rate that applies to your business before relying on the calculation.

How to choose the cheapest route for your business

For card checkout on your own website

Compare Worldpay and Square using the card mix you expect to receive. If most payments are standard UK cards, the published rates above give you a direct starting point. If you expect overseas, commercial or premium cards, use the relevant rate rather than the domestic headline figure.^1,2

For recurring invoices, subscriptions or retainers

Direct Debit can be worth comparing alongside cards. Check the collection method, charge per collection, any fixed fee or cap, mandate process, failed-payment handling and the customer experience before deciding. Its total cost can behave very differently from a card fee as invoice values rise.

For payment links and occasional online collections

Payment links can be practical if customers pay from an invoice, a follow-up email or a social message. SumUp and PayPal Point of Sale publish separate online or link pricing, while Wise Business can be relevant where its card-payment links or QR-code flow suits the way you collect.^3,4

For a Shopify store

Treat payment processing as part of the wider Shopify cost. Shopify's published card rate changes by plan, and the subscription cost can matter more than a few basis points of processing fee at lower sales volumes.⁵ Model the plan, payment rate and any extra app or third-party transaction costs together.

For larger or more technical payment operations

If you need multiple payment methods, international markets, custom checkout behaviour or a higher-volume contract, ask for an individual quote. Adyen's model combines a fixed processing fee with a payment-method fee, while Worldpay also offers pricing beyond its pay-as-you-go route.^1,6

A practical checklist before you sign up

1. List your expected monthly sales, average order value and number of payments.
2. Split that estimate between UK cards, overseas cards, wallets, Direct Debit and other methods.
3. Add all monthly, gateway, platform, payout and currency-related costs.
4. Model refunds and chargebacks if they are common in your sector.
5. Test the checkout or payment-link flow from a customer's point of view.
6. Recheck the provider's live pricing page before you make a final decision.

FAQs

What is the cheapest way to take online payments?

For a standard UK online card payment, compare the published percentage and fixed fee for providers such as Worldpay and Square. For recurring bank collections, compare Direct Debit pricing separately because its fee structure can be different. The cheapest route is the one with the lowest total cost for your customer mix, order values and checkout needs.^1,2

Which online payment is the cheapest?

There is no single cheapest method for every business. Card checkout can be convenient for one-off sales, Direct Debit can suit predictable regular collections, and a payment link can suit invoice-led collections. Compare the full rate for the payment method your customers will actually use, then add the platform and operational costs around it.

Is there a UK alternative to PayPal?

Yes. Square, Worldpay, Shopify Payments and other payment providers are among the routes UK businesses can compare, but they do different jobs. Start with whether you need card checkout, payment links, Direct Debit, an ecommerce platform or a tailored payments setup, then compare the relevant published or quoted price.^1,2,5

Do payment links cost less than website checkout?

They can be a simpler collection route, but they are not automatically cheaper. Check the provider's payment-link rate, card coverage, fixed fee, refund process and any subscription cost. The right choice depends on whether you need a full store checkout or simply a way to collect a payment from an invoice or message.^3,4
