| Every UK business selling online needs a payment gateway — the secure technology that processes customer card payments and transfers the money to your account. In 2026, the UK market offers a wide range of options from developer-friendly platforms like Stripe to consumer-trusted PayPal and high-volume specialists like Worldpay. Transaction fees vary significantly — for a business doing £100,000/year in online sales, choosing the right gateway can save £1,000–3,000 annually. | ||||||||||||||||||||||||||||||||||||||||
Our Verdict Stripe is the best payment gateway for most UK online businesses — transparent pricing (1.5% + 20p for UK cards), no monthly fee, excellent developer tools, and support for subscriptions, marketplaces, and international payments. PayPal is best when consumer recognition is a priority. Worldpay leads for high-volume businesses needing custom rates. Square is best for combined online and in-person payments. | ||||||||||||||||||||||||||||||||||||||||

Payment Gateway vs Merchant Account: What You Need | ||||||||||||||||||||||||||||||||||||||||
| For most UK SMEs, an all-in-one solution (Stripe, PayPal, Square) is the simplest option — these bundle the payment gateway and merchant account into a single product with one application, one monthly statement, and one support contact. Traditional separate gateway + merchant account arrangements (Worldpay + your business bank's merchant account) offer potentially lower rates at high volume but require managing two relationships and are harder to set up. | ||||||||||||||||||||||||||||||||||||||||

Frequently Asked QuestionsWhat is a payment gateway? A payment gateway is software that securely processes online card payments, authorising transactions between your customer's bank and your business bank account. It encrypts card data, sends it to the card network for authorisation, and either approves or declines the transaction in real time. Every online business that accepts card payments needs a payment gateway. What is the best payment gateway for UK small businesses? Stripe is the most popular payment gateway for UK startups and SMEs — transparent pricing (1.5% + 20p for UK cards), excellent developer tools, and easy setup. PayPal is the most recognised by consumers and has no monthly fee. Worldpay is the largest UK payment processor and offers competitive rates for higher-volume businesses. Square integrates payments with POS for combined online/offline businesses. How much does a payment gateway cost UK? UK payment gateway fees include a transaction fee (typically 1.2–2.9% + 20–30p per transaction) and sometimes a monthly fee (£0–25/month). Stripe: 1.5% + 20p (UK cards), no monthly fee. PayPal: 1.2–2.9% depending on volume, no monthly fee. Worldpay: from 0.75% + various fees (custom pricing at volume). SagePay (Opayo): from £25/month + transaction fees. What is the difference between a payment gateway and a merchant account? A payment gateway processes and authorises the transaction in real time. A merchant account is a bank account that holds funds before they are transferred to your business account. Some providers (Stripe, PayPal, Square) bundle both into one integrated solution. Traditional providers (Worldpay, Barclaycard) offer them separately. For most UK SMEs, an all-in-one gateway + merchant account solution is simpler. Do I need PCI DSS compliance for a payment gateway UK? Yes — all UK businesses that accept card payments must comply with PCI DSS (Payment Card Industry Data Security Standard). In practice, using a reputable payment gateway (Stripe, PayPal, Worldpay) means the gateway handles most of the PCI compliance on your behalf, reducing your compliance burden significantly. You will still need to complete an annual Self-Assessment Questionnaire (SAQ). | ||||||||||||||||||||||||||||||||||||||||
