Learning how to accept card payments UK is one of the most important steps any new or growing business can take. Customers across the UK increasingly expect to pay by card as their default — and businesses that cannot accommodate that risk losing sales before a conversation has even begun.
The process is far more straightforward than most first-time merchants expect. This guide walks you through everything you need to know, step by step.
Why Accepting Card Payments UK Is No Longer Optional for Small Businesses
Cash payments in the UK are in long-term decline. UK Finance data shows that debit card payments are now the most common form of payment in the UK, with billions of card transactions processed every year across the retail, hospitality, and service sectors. Contactless payments alone account for the majority of in-person card transactions.
For small businesses, this shift has a direct commercial impact. A customer who cannot pay by card at your market stall, café, or independent shop will often simply move on rather than look for a cash machine. The ability to accept card payments UK wide — quickly, securely, and reliably — is a fundamental part of operating any modern business.
The good news is that getting set up is genuinely accessible, even if you have never taken a card payment before.
What You Need to Accept Card Payments UK
To start taking card payments, every business needs three things working together: a merchant account, a payment terminal or solution, and a payment processor connecting the two.
A Merchant Account
A merchant account is a type of business bank account that holds funds from card transactions while they are being processed before they are transferred to your main business account. Many payment providers set up a merchant account for you as part of the onboarding process, so you do not need to arrange this separately.
When you accept card payments UK through a provider like NPI, the merchant account setup is handled as part of getting your payment solution up and running. You do not need to approach a bank independently.
A Payment Terminal or Card Machine
This is the device your customers use to pay. The right type of terminal depends on how and where your business operates.
A countertop card machine sits at a fixed point — a till, a reception desk, or a service counter — and is ideal for businesses with a dedicated checkout area. The PAX A35 is a compact, reliable option well suited to this setup.
A portable card machine uses 4G connectivity and a rechargeable battery, making it the right choice for businesses that take payments away from a fixed point — at the table in a restaurant, on the shop floor, at a market, or on the move. The PAX A50 is a popular option for this kind of flexibility.
An all-in-one EPOS terminal combines the card machine with a full point-of-sale system, managing payments, stock, staff performance, and reporting from a single device. The PAX A920 Pro, with its built-in receipt printer, is often used in restaurants and busier retail environments.
You can explore the full range of card machines available through NPI to find the right fit for your business type and size.
A Payment Processor
Your payment processor is the technology behind the scenes that authorises each transaction, communicates between your customer’s bank and your merchant account, and moves the funds through to settlement. NPI handles all of this as part of the payment solution, so there is nothing to configure on your end.
How to Accept Card Payments UK: The Types of Payment You Can Take
Once your terminal is set up, you can accept card payments UK customers make across a wide range of methods:
- Contactless card payments — a simple tap on the terminal, usually for amounts under £100
- Chip and PIN — the card is inserted and the customer enters their four-digit PIN
- Mobile wallets — Apple Pay, Google Pay, and Samsung Pay work through NFC technology on smartphones and smartwatches
- International cards — Visa and Mastercard issued in other countries
- Corporate and business cards
- Gift cards and loyalty cards when integrated with an EPOS system
The Payment Systems Regulator oversees payment services in the UK to ensure that card payment infrastructure is secure, accessible, and fair for both businesses and consumers. All NPI terminals operate fully within this regulatory framework.
Understanding the Costs When You Accept Card Payments UK
Every card transaction carries a processing fee. Understanding what makes up that cost helps you budget accurately and choose the right pricing structure for your business.
The fee on each transaction is made up of three parts. The interchange fee is paid to the customer’s bank and is capped at 0.2% for UK consumer debit cards and 0.3% for credit cards. The scheme fee is paid to Visa or Mastercard for using their network. The acquirer markup is your payment provider’s charge — and this is the element that varies between providers and can be negotiated.
For most small businesses, these costs are presented as a single blended rate per transaction — typically between 1.5% and 2.5% for in-person payments. Additional costs can include a monthly terminal rental fee, a PCI compliance charge, and in some cases a minimum monthly service fee.
NPI’s pricing is fully transparent, with all charges disclosed clearly before you commit to anything. There are no surprise fees appearing after the first statement, and no rate increases mid-contract.

How to Accept Card Payments UK Online and Remotely
For businesses that sell online or take payments by telephone, accepting card payments UK does not require a physical terminal.
An online payment gateway integrates directly into your website, allowing customers to pay through a secure checkout page on any device. NPI’s online payment solution is designed for straightforward integration and supports mobile-friendly checkout as standard.
A virtual terminal lets you take card payments over the phone or by email. You log in to a secure portal, enter the customer’s card details on their behalf, and process the payment remotely. This is particularly useful for service businesses, tradespeople, and anyone taking deposits or booking fees before a job or appointment.
Payment links — sent by SMS, email, or shared as a QR code — let customers pay without a website or a physical terminal, making them ideal for mobile businesses and one-off transactions.
You can explore all of NPI’s virtual payment options to find the right remote payment setup for how your business operates.
What Happens After You Accept Card Payments UK: Settlement Explained
Once a card payment is processed, the funds move through the payment chain and arrive in your business bank account through a process called settlement. The speed of this process varies significantly between providers.
Many traditional providers settle on a two to five day cycle, meaning money you earned on Monday may not reach your account until Thursday or Friday at the earliest. NPI offers next-day settlement as standard, meaning funds from your card transactions arrive in your account the following working day — keeping your cash flow healthy and predictable.
UK Finance guidance emphasises that cash flow management is one of the most significant challenges for small businesses, and settlement speed is a direct contributor to how comfortably a business can manage its day-to-day finances.

Getting started with NPI is a straightforward process. Your dedicated account manager works with you to understand your business type, transaction volumes, and the way you operate before recommending the right solution.
Once you have agreed a setup, NPI handles hardware delivery, on-site installation, and network configuration.
