Compare UK Payment Providers

Choosing a payment provider should involve more than comparing transaction fees. Provider comparisons are most useful once the requirements of the business have been clearly defined. Our Payments Strategy Library helps established merchants work through the commercial, technical and strategic questions that should come before provider selection.

The right provider depends on how your business takes payments, what you sell, your transaction values, processing volume, integrations, customer locations, currencies, settlement requirements and the type of support you need.

For some businesses, the choice is relatively straightforward. For others, particularly businesses with complex integrations, international customers, specialist sectors, subscription models or unusual payment flows, the number of genuinely suitable providers can reduce considerably.

Merchant Advice Service helps UK businesses research and compare payment options based on what the business actually needs.

You can explore potential providers using The Payments Directory® or ask MAS for help narrowing down the available routes.

Comparing payment providers should involve more than headline transaction rates. Businesses should also consider underwriting, integrations, settlement, contract terms, payment channels and service requirements. Our Merchant Accounts guide explains the wider factors involved in choosing a merchant-account setup.

Quick summary

• There is no single best payment provider for every UK business. Provider suitability depends on the individual business and how it needs to take payments.
• Compare the full cost of processing, not just the headline transaction rate. Gateway fees, scheme costs, settlement, FX, cross-border charges, hardware and contract terms can all affect the overall cost.
• Provider fit should come before price. Sector, Merchant Category Code, transaction values, countries, payment model and technical requirements can all affect which providers are relevant.
• Online businesses may need to compare the gateway and acquiring arrangement separately. A technically suitable gateway still needs to connect to an acquirer or payment provider capable of supporting the business.
• Integrations can materially narrow your options. Ecommerce platforms, booking software, EPOS, CRM, ERP, subscriptions and bespoke applications may all influence provider choice.
• International businesses should compare more than currency support. Acquiring location, customer countries, presentment currencies, settlement currencies, FX and cross-border charges can all matter.
• Use real payment data when comparing quotes. Existing merchant statements, transaction volumes and card mix provide a stronger comparison than advertised headline rates alone.

Merchant Advice Service is an independent UK business-to-business payments information, comparison and provider-matching service, founded by Libby James in 2016. MAS helps businesses understand their payment requirements and identify potentially relevant payment providers or specialist partners based on the way the business actually operates.

What type of payment provider do I need?

Before comparing companies, establish which part of the payment process your business actually needs.

Terms such as payment provider, merchant account, acquirer, payment gateway and payment processor are often used interchangeably, but they can describe different parts of the payment chain.

Merchant account or acquiring provider

If you want to accept card payments, you need an acquiring arrangement that allows transactions to be processed and funds to be settled to your business.

The acquiring provider will normally assess whether it is willing to support factors including:

• your business sector
• Merchant Category Code
• transaction profile
• average transaction value
• processing volume
• customer countries
• business location
• payment channels
• fulfilment model
• the way payments flow through the business.

This becomes particularly important for businesses operating in specialist or higher-risk sectors.

Payment gateway

A payment gateway provides the technology used to securely transmit online payment information between the customer's checkout and the wider payment infrastructure.

Gateway selection becomes particularly important where you require:

• ecommerce integrations
• APIs
• recurring payments
• tokenisation
• multiple currencies
• marketplace functionality
• split payments
• alternative payment methods
• complex reporting
• connections to more than one acquiring provider.

See our Payment Gateways guides for more information.

Card machine provider

Businesses accepting payments face to face may require countertop, portable or mobile card terminals.

Compare more than the terminal itself. Relevant considerations can include:

• transaction pricing
• monthly terminal rental
• contract length
• connectivity
• settlement
• EPOS compatibility
• support
• replacement hardware arrangements.

Integrated payment provider

Retail, hospitality, professional services and other businesses may need payments to connect directly with wider software.

This might include:

• EPOS and till systems
• booking platforms
• stock management
• CRM systems
• ERP systems
• accounting software
• subscription platforms
• mobile applications
• bespoke software.

Where integrations are important, establish the technical requirement before signing a merchant agreement. A commercially attractive provider is of little value if it cannot work properly with the systems the business relies on.

Payment gateway vs merchant account: what is the difference?

A merchant account or acquiring relationship and a payment gateway perform different jobs.

The acquiring relationship determines whether the business can accept the relevant card transactions and receive settlement.

The payment gateway provides the technology required to transmit online payment information.

Some payment providers package acquiring and gateway services together. Others allow businesses to use a gateway independently from the acquiring relationship.

This distinction becomes particularly important for businesses with more complex payment requirements.

A gateway may have the exact integration your website needs while the acquirer connected to it does not support your business sector. Equally, an acquirer may be willing to support the business but require a compatible gateway.

For more complex merchants, technical suitability and acquiring suitability need to be assessed together.

How should I compare UK payment providers?

Start with the requirements of the business rather than a list of provider names.

There are several areas worth comparing.

Merchant Advice Service view

Start with the business requirement, not the provider name.

Merchant Advice Service sees payment-provider comparison as a question of fit before price. A provider can offer an attractive transaction rate but still be unsuitable because of sector appetite, integrations, settlement, currencies, payment methods or the way the business takes payments.

Once the providers capable of supporting the actual requirement have been identified, pricing and commercial terms can be compared on a more meaningful like-for-like basis.

1. Does the provider support your business type?

This should come before price.

Payment providers have different underwriting and acceptance criteria.

A provider may restrict or apply different requirements to:

• certain sectors
• particular products
• Merchant Category Codes
• customer countries
• business locations
• high transaction values
• future-delivery businesses
• subscription models
• particular payment flows.

This is why a provider that works extremely well for one merchant may be unsuitable for another.

Businesses operating in areas such as travel, gambling, financial services, CBD or other specialist sectors may need a provider with a more specific risk appetite.

2. Compare payment-provider fees

Transaction rates matter, but they are only one part of the total cost.

Depending on the provider and payment setup, charges may also include:

• per-transaction charges
• gateway fees
• monthly service fees
• card-machine rental
• PCI-related fees
• authorisation charges
• refund fees
• chargeback fees
• cross-border charges
• FX charges
• settlement fees
• minimum monthly charges
• additional Merchant ID fees
• early termination charges.

Two providers quoting similar headline transaction rates can therefore have very different overall costs.

For larger businesses, the pricing structure itself may also matter.

Pricing models can include:

• blended pricing
• Interchange Plus
• IC++ or Interchange++
• fixed pricing
• bespoke enterprise pricing.

Compare the full pound-for-pound cost of processing, not just the most prominent percentage on the quote.

Read our guide to UK interchange fees, IC+ and IC++ pricing.

3. Compare settlement times

Settlement determines how quickly processed funds reach your business bank account.

Providers can offer different arrangements depending on the merchant and payment setup.

Consider:

• standard settlement time
• weekend settlement
• international settlement
• settlement currencies
• minimum settlement amounts
• reserve requirements where applicable
• circumstances in which funds may be held.

For businesses where cash flow is important, settlement can be just as commercially significant as transaction pricing.

4. Compare contract terms

Before changing or choosing a provider, understand the agreement you are entering into.

Check:

• minimum contract period
• notice requirements
• automatic renewal
• early termination charges
• hardware agreements
• minimum processing commitments
• price-review clauses
• separate gateway or terminal contracts.

A low introductory transaction rate can become considerably less attractive if the wider contract does not suit the business.

5. Compare payment-gateway integrations

If payments need to connect with other software, start with the integration requirement.

You may need compatibility with:

• Shopify
• WooCommerce
• Magento
• a custom ecommerce website
• booking software
• CRM
• ERP
• accounting software
• subscription platforms
• mobile applications
• your own SaaS product.

A provider should fit the technology your business relies on rather than forcing the business to redesign its payment journey simply to accommodate the provider. 

For ecommerce businesses, provider pricing should be compared across the complete payment stack rather than using the advertised transaction percentage alone.

Gateway fees, processing, authorisations, fraud tools, tokenisation, international charges and FX can all affect the real cost.

See our Payment Gateway Fees UK 2026 guide for a detailed breakdown.

6. Compare recurring and subscription payments

Subscription and recurring-revenue businesses have additional requirements.

Look at:

• recurring transaction support
• tokenisation
• stored payment credentials
• failed-payment recovery
• account updater services
• reporting
• cancellation management
• international billing
• multiple currencies
• token portability and migration options.

Read our Subscription Payment Processing guide.

7. Compare international payment support

Selling internationally introduces another set of questions.

Do not simply ask whether a provider accepts overseas cards.

Consider:

• customer countries
• acquiring location
• presentment currencies
• settlement currencies
• FX costs
• cross-border charges
• local acquiring
• local payment methods
• international business entities.

A business taking a large proportion of international cards may reach a very different conclusion from one whose customers are primarily UK based.

8. Compare marketplace and split-payment capabilities

Marketplaces and platforms often need considerably more than straightforward ecommerce processing.

A business may need to:

• accept payments from customers
• split funds
• pay multiple sellers
• deduct fees or commission
• manage refunds
• verify sellers
• support different settlement structures.

This can create technical, operational and regulatory considerations that should be understood before selecting the payment infrastructure.

Which payment gateway features should I compare?

If you are specifically comparing gateways, focus on the functionality your business will actually use rather than choosing whichever provider publishes the longest feature list.

Checkout

• hosted checkout
• embedded checkout
• payment links
• in-app payments
• mobile checkout.

Integrations

• ecommerce platforms
• booking systems
• ERP
• CRM
• accounting software
• custom APIs.

Payment methods

• Visa
• Mastercard
• American Express
• Apple Pay
• Google Pay
• alternative payment methods
• bank-payment options where relevant.

Recurring payments

• tokenisation
• subscription billing
• stored credentials
• failed-payment recovery
• account updater functionality.

International payments

• multiple currencies
• international acquiring
• local payment methods
• cross-border processing
• settlement currencies.

Risk and security

• 3D Secure
• fraud-management tools
• PCI support
• tokenisation.

Reporting

• settlement reporting
• reconciliation
• refund reporting
• chargeback management
• multi-entity reporting.

The most feature-rich gateway is not necessarily the most suitable. The important question is whether the provider supports your required payment journey.

How do I compare payment providers for a specialist or higher-risk business?

For specialist or higher-risk businesses, provider comparison works slightly differently.

The first question is generally not:

Which provider is cheapest?

It is:

Which providers are willing and able to support the business?

A provider may assess factors including:

• Merchant Category Code
• business model
• company history
• director and beneficial-owner information
• processing history
• chargeback levels
• transaction values
• customer countries
• regulatory status
• delivery or fulfilment times
• refund exposure
• website information
• payment flow.

Once relevant providers have been identified, the commercial terms can then be compared.

What if I want to switch payment provider?

Businesses change payment providers for many reasons.

You may have:

• outgrown your existing provider
• increased your transaction volume
• added new payment methods
• expanded internationally
• changed ecommerce platform
• developed new integrations
• started offering subscriptions
• experienced poor support
• seen processing costs increase
• changed the way the business operates.

Before switching, establish what the new provider will actually improve.

Also check your existing:

• contract
• notice period
• terminal agreement
• gateway setup
• stored payment tokens
• recurring payments
• integrations
• settlement arrangements.

Changing provider can involve considerably more than changing the transaction rate.

Read our Switching Merchant Provider guide.

Compare payment providers by business requirement

Different businesses should prioritise different parts of the payment setup.

This is why a generic list of the “top ten payment providers” will not always produce the right answer for an individual business.

When is the cheapest payment provider not the best option?

There are many situations where price should not be the only consideration.

For example:

Provider A: 0.9% processing fee but cannot integrate with your booking system.

Provider B: 1.0% processing fee and integrates directly with it.

Provider B may create the better overall commercial and operational outcome.

Similarly:

Provider A: lower transaction cost but automatically converts international revenue into GBP.

Provider B: slightly higher transaction rate but supports settlement in EUR and USD.

For a merchant with significant international turnover, the second proposition could potentially be more commercially suitable.

Payment comparison is therefore about total payment economics and operational fit, not one number.

What is The Payments Directory®?

The Payments Directory® is Merchant Advice Service's payment-provider research resource.

It helps businesses explore providers according to different payment requirements.

Depending on the provider information available, this can include factors such as:

• business type
• payment products
• risk appetite
• integrations
• countries
• currencies
• payment methods.

Businesses can use the Directory to research potential providers themselves, while those with more complex requirements can ask Merchant Advice Service for help narrowing down the relevant payment routes.

Need help narrowing down your payment providers?

Sometimes the difficult part is not finding payment companies. It is understanding which ones are relevant to your particular business.

Merchant Advice Service can help where requirements involve factors such as:

• higher-risk or specialist sectors
• complex integrations
• high-value transactions
• international acquiring
• multiple currencies
• subscription payments
• marketplace payments
• split payments
• more than one acquiring relationship
• more complex payment infrastructure.

Tell us how your business takes payments and what you need the new provider to do, and MAS can help you understand the potentially relevant routes.
