Accepting payments efficiently is fundamental to every UK business. The payment processing landscape in 2026 offers a diverse range of solutions, from card payment processors like Stripe and Square to direct debit specialists like GoCardless, alongside the UK's domestic payment infrastructure including Faster Payments, BACS, and CHAPS. Choosing the right mix of payment methods directly affects your costs, cash flow, and customer experience.
This guide provides a comprehensive comparison of payment processing options available to UK businesses. It covers card payment processors, direct debit providers, Open Banking solutions, and the UK's interbank payment systems. Each section includes fee breakdowns, use cases, and practical guidance for selecting the most appropriate solution for your business.
Card Payment Processing
Card payments remain the dominant payment method for UK consumer transactions and are increasingly important for B2B payments. The major card payment processors serving UK businesses each have distinct strengths.
Stripe
Stripe is the most widely used online payment processor for UK businesses, particularly those with e-commerce, SaaS, or subscription-based business models.
| Fee Component | Rate |
|---|---|
| UK cards | 1.5% + 0.20 GBP |
| European cards | 1.5% + 0.20 GBP |
| Non-European cards | 2.5% + 0.20 GBP |
| Monthly fee | None |
| Setup fee | None |
| Refund fee | 0.20 GBP (original transaction fee not returned) |
| Dispute/chargeback fee | 15 GBP |
| Payout time | 2 working days (standard) |
Stripe's strengths include comprehensive API documentation, extensive integration options, built-in fraud protection (Radar), support for 135+ currencies, and features like subscription billing, invoicing, and payment links. It is the default choice for technology companies and online businesses.
Square
Square is best known for in-person card payments via its point-of-sale hardware, but it also offers online payment processing.
| Fee Component | Rate |
|---|---|
| In-person (chip and PIN / contactless) | 1.6% |
| Online payments | 1.4% + 0.25 GBP (UK cards), 2.5% + 0.25 GBP (non-UK) |
| Card-not-present (keyed) | 2.5% |
| Monthly fee | None (free tier) |
| Hardware | Square Reader: 19 GBP; Square Terminal: 149 GBP |
| Payout time | Next working day |
Square is particularly suited to retail, hospitality, and service businesses that need both in-person and online payment capabilities. Its free point-of-sale software and next-day payouts are key advantages for small businesses.
SumUp
SumUp positions itself as the simplest and most affordable card reader for small businesses and sole traders.
| Fee Component | Rate |
|---|---|
| In-person transactions | 1.69% |
| Online payments | 2.5% |
| Monthly fee | None |
| Card reader | SumUp Air: 29 GBP; SumUp Solo: 79 GBP |
| Payout time | 1-3 working days |
SumUp is ideal for micro-businesses, market stalls, tradespeople, and mobile businesses that need a simple, low-cost card acceptance solution without the complexity of a full POS system.
When comparing card payment processors, the headline transaction rate is only part of the picture. Businesses should also consider payout speed (how quickly funds reach your bank account), integration capabilities (does it work with your website, accounting software, and inventory system?), international payment support, and the quality of dispute handling. For high-volume businesses, even a 0.1% difference in transaction fees can amount to thousands of pounds per year. Our analysts recommend running a cost comparison based on your actual transaction mix (domestic vs international, in-person vs online, average transaction value) before committing to a provider.

Direct Debit: GoCardless and Alternatives
Direct Debit is one of the most cost-effective payment methods for UK businesses that collect recurring payments. It uses the BACS Direct Debit scheme, which is trusted by UK consumers and provides predictable cash flow for businesses.
GoCardless
GoCardless is the leading Direct Debit provider for UK businesses, particularly those collecting subscriptions, memberships, or recurring invoices.
| Plan | Transaction Fee | Monthly Fee | Features |
|---|---|---|---|
| Standard | 1% + 0.20 GBP (capped at 2 GBP) | Free | Core DD collection, dashboards, API |
| Advanced | 1% + 0.20 GBP (capped at 2 GBP) | 30 GBP | Custom branding, webhook notifications, Smart Retries |
| Pro | Custom pricing | Custom | Multi-currency, premium support, advanced integrations |
GoCardless handles the entire Direct Debit process: creating mandates, collecting payments on schedule, retrying failed payments, and managing customer notifications. It integrates with major accounting and billing platforms including Xero, QuickBooks, Zuora, and Salesforce.
How Direct Debit Works
- The customer authorises a Direct Debit mandate (can be done online via GoCardless or paper form)
- The business submits collection requests through GoCardless
- GoCardless submits the instruction to BACS
- BACS processes the payment (3 working days)
- Funds are collected from the customer's bank account and deposited to the business account
The key advantage of Direct Debit over card payments for recurring charges is lower cost per transaction (especially for larger amounts, where the 2 GBP cap makes it dramatically cheaper than percentage-based card fees) and lower failure rates (cards expire, Direct Debit mandates persist until cancelled).
Direct Debit Guarantee
The Direct Debit Guarantee protects payers by allowing them to request an immediate refund from their bank if a payment was collected in error. While this creates a risk for businesses (similar to chargebacks), it also builds trust with customers and is a well-understood consumer protection in the UK.
For businesses collecting recurring payments above 50 GBP, Direct Debit through GoCardless is almost always cheaper than card payments. A 200 GBP monthly subscription collected by Direct Debit costs 2 GBP (the capped amount) versus 3.20 GBP via Stripe (1.5% + 0.20 GBP). Over a year with 1,000 customers, that is a saving of 14,400 GBP. The lower failure rate of Direct Debit compared to card payments (which fail due to expired cards, insufficient funds flagged differently, and card scheme rules) further improves revenue collection. For detailed guidance on business banking, see our UK business bank account guide.
Open Banking Payments
Open Banking is transforming UK payment processing by enabling direct bank-to-bank payments without intermediary card networks. Introduced under PSD2 regulation and enabled by the UK's Open Banking Implementation Entity (OBIE), it allows authorised third-party providers to initiate payments directly from customer bank accounts.
How Open Banking Payments Work
- The customer selects "Pay by bank" at checkout
- They are redirected to their bank's authentication (usually mobile app approval)
- The payment is initiated instantly via Faster Payments
- Funds arrive in the merchant's account within seconds to minutes
- The transaction is confirmed and the customer is returned to the merchant's site
Open Banking Providers
| Provider | Fees (Typical) | Features |
|---|---|---|
| TrueLayer | 0.5% or fixed fee per transaction | Payment initiation, account information, identity verification |
| Yapily | From 0.1% per transaction | Payment initiation, account data, multi-country |
| Plaid | Custom pricing | Account linking, identity verification, payment initiation |
| Ecospend (NatWest) | Custom pricing | UK-focused, HMRC partnership |
| Volt | Custom pricing | Multi-country payment initiation |
Advantages of Open Banking Payments
- Lower fees. Typically 0.1% to 0.5% per transaction, significantly less than card processing fees
- Instant settlement. Funds arrive via Faster Payments, usually within seconds
- No chargebacks. Bank transfers cannot be reversed like card payments (reducing fraud risk)
- Higher conversion. Some merchants report higher conversion rates due to the streamlined authentication flow
- Real-time confirmation. Both merchant and customer know immediately whether the payment has succeeded
Limitations
- Customer awareness. Not all customers are familiar with paying by bank transfer at checkout
- Browser redirects. The payment flow involves redirecting to the customer's banking app, which can cause drop-off
- No recurring payments (yet). Open Banking recurring payments (Variable Recurring Payments) are still being rolled out
- Refund process. Refunds must be initiated separately by the merchant as a bank transfer
UK Interbank Payment Systems
Understanding the UK's underlying payment infrastructure helps businesses choose the most appropriate payment method for different transaction types.
Faster Payments Service (FPS)
Faster Payments is the UK's real-time payment system. Launched in 2008, it handles the majority of UK electronic payments.
| Feature | Detail |
|---|---|
| Speed | Near-instant (typically seconds, maximum 2 hours) |
| Maximum transaction | 1 million GBP (individual bank limits may be lower) |
| Operating hours | 24/7/365 |
| Cost for businesses | Free or very low (typically included in bank account) |
| Use cases | Supplier payments, salary transfers, customer refunds, inter-account transfers |
BACS
BACS (Bankers' Automated Clearing Services) processes both Direct Debit collections and Direct Credit payments.
| Feature | Detail |
|---|---|
| Speed | 3 working days (Day 1: input, Day 2: processing, Day 3: settlement) |
| Maximum transaction | No upper limit |
| Operating hours | Processing on working days only |
| Cost for businesses | 0.05-0.50 GBP per item (through a BACS-approved bureau or software) |
| Use cases | Payroll, supplier payments, Direct Debit collections, pension contributions |
BACS Direct Credit is the standard method for paying employee salaries in the UK. The 3-day processing cycle means payroll must be submitted in advance of the payment date.
CHAPS
CHAPS (Clearing House Automated Payment System) provides guaranteed same-day settlement for high-value payments.
| Feature | Detail |
|---|---|
| Speed | Same working day (guaranteed if submitted by bank's cut-off, usually 2-4pm) |
| Maximum transaction | No upper limit |
| Operating hours | Working days only (typically 6am to 6pm) |
| Cost for businesses | 20-35 GBP per payment |
| Use cases | Property purchases, large business-to-business payments, urgent high-value transfers |
For most day-to-day business payments, Faster Payments has effectively replaced BACS Direct Credit for smaller volumes and CHAPS for non-urgent high-value payments. The key remaining use cases for BACS are bulk payroll processing (where the per-item cost is lower) and Direct Debit collections. CHAPS remains essential for transactions where guaranteed same-day settlement is legally or commercially required, such as property completions and securities settlement. For information on choosing a business bank account that supports these payment methods, see our bank account guide.
Choosing the Right Payment Mix
Different business models require different payment strategies. Here is a practical guide based on business type:
E-Commerce and Online Businesses
- Primary: Stripe for card payments (online checkout, payment links)
- Supplement with: Open Banking payments for higher-value orders (lower fees, instant settlement)
- Consider: Apple Pay and Google Pay via Stripe (improving mobile conversion)
Subscription and SaaS Businesses
- Primary: GoCardless for Direct Debit (lowest cost for recurring payments)
- Supplement with: Stripe for card payments (international customers, one-off purchases)
- Consider: Stripe Billing for complex subscription management with mixed payment methods
Retail and Hospitality
- Primary: Square for in-person card payments (POS system, inventory management)
- Supplement with: Stripe or Square Online for e-commerce/delivery orders
- Consider: SumUp if simplicity and low cost are priorities over features
Professional Services and B2B
- Primary: Bank transfers via Faster Payments (no transaction fees for invoice payments)
- Supplement with: GoCardless for recurring retainer payments
- Consider: Stripe Invoicing for clients who prefer to pay by card
Marketplace and Platform Businesses
- Primary: Stripe Connect (handles split payments, seller payouts, tax reporting)
- Supplement with: Open Banking for lower-fee alternatives
- Consider: PayPal for international marketplace sellers/buyers
International Payment Processing
For UK businesses that sell to international customers, the payment processing choice significantly affects costs and conversion rates.
Cross-Border Card Payments
When a UK business accepts a card issued in another country, the processing fee is typically higher than for domestic transactions. Stripe charges 2.5% + 0.20 GBP for non-European cards, compared to 1.5% + 0.20 GBP for UK cards. For businesses with a high proportion of international sales, this difference adds up substantially.
Multi-Currency Pricing
Offering prices in the customer's local currency can improve conversion rates by 10-20% compared to showing prices only in GBP. Stripe, PayPal, and Adyen all support multi-currency pricing, allowing you to display prices in the customer's currency while settling in GBP.
The foreign exchange conversion adds a margin of 1-2% on top of the transaction fee. Businesses should factor this into their pricing strategy.
Alternative Payment Methods by Market
| Market | Preferred Payment Methods |
|---|---|
| EU / UK | Cards, Direct Debit, bank transfer |
| United States | Cards, ACH (direct debit equivalent), Apple Pay |
| Germany | Bank transfer (Giropay, Sofort), PayPal, invoice |
| Netherlands | iDEAL (bank transfer), cards |
| China | Alipay, WeChat Pay |
| India | UPI, cards, net banking |
| Brazil | Pix, Boleto, cards |
Stripe and Adyen support many of these local payment methods, allowing UK businesses to offer relevant payment options to customers in different markets.
Reconciliation and Accounting Integration
Efficient payment reconciliation is essential for accurate financial reporting and tax compliance. All major payment processors integrate with UK-popular accounting platforms.
| Processor | Xero | QuickBooks | FreeAgent | Sage |
|---|---|---|---|---|
| Stripe | Yes (native) | Yes (native) | Yes | Yes (via plugin) |
| Square | Yes (native) | Yes (native) | Limited | Yes |
| GoCardless | Yes (native) | Yes (native) | Yes | Yes |
| PayPal | Yes (native) | Yes (native) | Yes | Yes |
| SumUp | Yes (via plugin) | Yes (via plugin) | Limited | Limited |
Automated reconciliation saves significant bookkeeping time and reduces errors. For businesses processing hundreds or thousands of transactions per month, the integration between payment processor and accounting software should be a key selection criterion.
Regulatory Considerations
Payment processing in the UK is regulated by the Financial Conduct Authority (FCA). Businesses should be aware of:
- PCI DSS compliance. Any business that processes, stores, or transmits card data must comply with the Payment Card Industry Data Security Standard. Using a hosted payment page (like Stripe Checkout) significantly reduces PCI compliance burden. PCI DSS has four levels of compliance based on transaction volume, with most small businesses falling into Level 4 (fewer than 20,000 e-commerce transactions per year) which requires only a self-assessment questionnaire.
- Strong Customer Authentication (SCA). UK regulations require SCA (typically 3D Secure) for most electronic payments. Payment processors like Stripe handle SCA automatically. Certain transactions are exempt from SCA, including low-value transactions under 30 GBP, recurring payments, and transactions assessed as low risk by the issuing bank.
- Data protection. Payment data is personal data under UK GDPR. Ensure your payment processing arrangements comply with data protection requirements.
- Consumer rights. Businesses selling to consumers must comply with the Consumer Rights Act 2015, which includes the right to a refund for faulty goods and a 14-day cooling-off period for online purchases.
- Anti-money laundering. Businesses processing significant payment volumes may be subject to anti-money laundering regulations. Payment processors conduct their own AML checks, but businesses should also implement appropriate controls.
Payment processing is an area where ongoing monitoring is essential. Transaction fees, exchange rates, and service terms change regularly, and what was the best option a year ago may no longer be optimal. Our analysts recommend reviewing your payment processing costs at least annually, comparing actual costs (not just advertised rates) across providers, and renegotiating terms if your transaction volume has grown significantly. For many businesses, a 0.2% improvement in processing costs translates to meaningful annual savings. For guidance on the broader financial infrastructure, see our business bank account guide.
Conclusion
The UK payment processing landscape offers solutions for every business model and budget. For online businesses, Stripe provides the most comprehensive feature set. For recurring payments, GoCardless offers the lowest cost through Direct Debit. For in-person sales, Square and SumUp provide accessible card acceptance. Open Banking is emerging as a cost-effective alternative that benefits from instant settlement and lower fees.
The optimal strategy for most businesses involves combining multiple payment methods to serve different customer preferences and transaction types. The key metrics to evaluate are total cost per transaction (including FX margins and hidden fees), settlement speed, integration with your existing systems, and the payment experience offered to your customers.
