Best Payment Gateway Providers in UK for e-Commerce Website


With the rise of online shopping, providing payment details on an e-commerce website has become a common phenomenon. Yet, buyers prioritise the safety and security of their personal information, especially with the various payment options available.

For businesses, establishing trust with their customer base is paramount. Implementing secure payment gateways is essential to ensuring safe transactions over the Internet. A reliable payment gateway does more than just facilitate transactions – it instils confidence in customers, leading to increased conversion rates and repeat purchases, benefiting businesses in the long run.

To assist you in selecting the right payment gateway for your business needs, read on to discover everything you need to know about payment gateways. Also, explore some of the best options available for eCommerce websites in the UK.

What is a Payment Gateway?

A payment gateway is an online service that enables businesses and individuals to accept payments from customers through their websites or mobile applications. It provides various payment options, such as debit and credit cards, digital wallets, UPI, and more. Businesses utilising these services are often referred to as merchants. Essentially, a payment gateway serves as an intermediary between a merchant and the financial institution processing the payment.

In simple terms, a payment gateway is a technology used by merchants to facilitate electronic payments. It enables online shoppers to use credit or debit cards to purchase products or services.

Types of Payment Gateways

As a merchant, it's essential to understand three main types of payment gateways: on-site payments, redirects, and off-site payments.

1. On-site Payments: With on-site payments, customers can complete transactions without leaving the retailer's website, as seen on platforms like Amazon and eBay. This creates a seamless checkout experience, ultimately enhancing customer satisfaction.

2. Redirects: Redirects occur when a company presents alternative payment options at the checkout. Customers are then directed to another platform or website to finalise their payment.

3. Off-site Payments: In off-site payments, the front-end checkout process takes place on the merchant's website, but the actual payment is processed through a separate back-end system. This approach allows for a streamlined checkout experience while ensuring secure payment processing.

How do Payment Gateways Work? 

1. Collection

When a customer makes a purchase and enters their payment details, such as credit card information, on your website, they hit the payment button to initiate the transaction.

2. Transmission

The payment gateway securely transmits the encrypted payment information to the payment network, ensuring the confidentiality and integrity of the data during transmission.

3. Verification and Authorization

The payment gateway sends an authorization request to the payment network, seeking approval to process the payment. The payment network verifies details like the billing address and the card security code (CVV) to authenticate the transaction.

4. Completion

After receiving the authorization response from the payment network, the payment gateway communicates the outcome back to the merchant's website or application. This notification indicates whether the transaction was successful or unsuccessful.

This entire process typically takes only a few seconds. However, factors such as errors, chargebacks, fraud claims, and other issues may slow down the payment process and cause delays in transaction completion. Payment gateways may charge a fee for their services, which can be a percentage of the transaction amount or a flat fee.

How to Choose the Best Payment Gateway Provider for Your Business?

When selecting an online payment gateway provider in the UK, several crucial factors play a role in ensuring a smooth and secure transaction process for both your business and your customers. Here's how to make the best choice:


The security of your payment gateway should be your top priority since it stores sensitive information. Ensure that the gateway is level-1 PCI DSS compliant and equipped with fraud detection tools to prevent unauthorised activities.

Easy to integrate

However, you can learn from our guide on how to add a payment gateway into a website to make things easier for you.


Consider the cost of the payment gateway, including transaction fees, monthly charges, and any additional costs. Choose a provider that offers the necessary features within your budget and consider long-term scalability as your business expands.

Customer support 

Reliable customer support is essential for addressing customer queries and complaints. Choose a payment gateway with responsive support services to ensure prompt assistance when needed.

Bank Settlement Time

While payments may be approved immediately, it typically takes a few days for the funds to settle in your account. This time frame varies from 1-7 days, depending on the service provider. Consider your cash flow needs when deciding whether to opt for immediate payment or wait for settlement. Working with a reputable e-commerce development agency can help streamline this process so you can optimise your cash flow management strategies.
