Payment Gateway Provider in the UK: 7 Companies to Compare in 2026

Located in the UK? If you are assessing payment gateway providers, there are a number of factors that you may want to review beyond just comparing rates. Your payment gateway provider will be a part of your checkout flow, payment approval process, impact your cash flow and exposure to fraud and will help you access payments in other markets.

For lower volume, lower value card transactions, a more basic payment processing solution may be adequate. For a subscription business, you may need a solution that has dependable, recurring billing. A business that serves a more international clientele may require payment processing in a number of international currencies and payment methods.

Some high risk businesses may require an underwriting process and support that helps ease the burden of compliance, fraud, and cash flow.

This guide reviews seven payment gateway processors that may be adequate for your business needs in 2026: WebPays, Stripe, PayPal, Paycly, BoxChrge, inquid.net and Worldpay. The right option will be based on your business needs, location and what you are looking to process.

What Is a Payment Gateway Provider?

Payment gateway providers enable a business to process electronic payments through its website and/or mobile application. Payment gateways facilitate the secure transfer of payment information and provides the means to authenticate transactions. The payment gateway interfaces with the merchant system to provide results of the payment transaction.

A payment gateway provides the means for a merchant to obtain approval for a customer payment. The approval process is initiated when card details are entered at a point of payment. The customer bank evaluates the payment and communicates the result to the merchant payment system.

A payment gateway provides a link between the merchant and the payment system, and ensures that payment transactions proceed to the next step in the process. Some payment gateway providers also process payment transactions and facilitate settlement of those transactions. Others have agreements with acquiring banks or other payment partners to fulfill this function.

Before executing an agreement with a payment gateway provider, have clarity on the payment system that will process the payment transactions and the organization that will be responsible for payment transaction settlement.

Payment Gateway vs Payment Processor vs Merchant Account

While closely related, these terms denote specific elements of a payment process.

• Payment gateway: - A payment gateway securely provides the technology to accept payment and transmit it to a processor.
• Payment processor: - A payment processor facilitates the movement of a transaction between the parties involved, e.g. buyer and seller, financial institutions, etc.
• Merchant account: - A merchant account is a commercial account, opened by a merchant, through which payment for a service/good is received and cleared.

Oftentimes, a payment gateway service provides all the above under an agreement. Otherwise, a business has to use different services for each of the above.

Identifying each of these helps to accurately decipher the true costs associated with each service. For example, a low gateway service fee may ultimately prove costly.

How Does an Online Payment Gateway Work?

Consider a customer purchasing a product from a UK website. The payment process generally follows these steps:

1. The customer selects a product and chooses a payment method at checkout.
2. The gateway securely transmits the payment information.
3. The transaction is routed through the relevant processor, card network and acquiring arrangements.
4. The customer bank evaluates the transaction and returns an authorisation decision.
5. The merchant receives confirmation of the result.
6. Approved transactions move through clearing and settlement, subject to the provider's payout schedule and any applicable holds.

Fraud and payment insufficiency may be determined at this or other points in the process. While the process may vary depending on the payment service provider and the type of payment, Strong Customer Authentication will generally be applied in line with the applicable exemptions. The Payment Services Regulations 2017 establish rules on authentication for payment transactions falling within the scope of the regulations.

An integrated payment gateway simplifies the process for the customer and helps the merchant manage payment and transaction information.

7 Payment Gateway Companies to Compare in the UK

No single payment provider is the right fit for every business. The shortlist below includes a mix of general payment platforms and providers worth exploring based on your specific needs. But WebPays stands out from the rest by supporting high-risk industries such as offshore business, international payments, crypto, vitrual banking or payments, digital banking, open banking, gaming, adult entertainment, casinos, CBD, and other high-risk businesses.

WebPays

WebPays is a payment services brand focused on higher risk businesses. If you’re having difficulties with other payment providers, you may want to consider a merchant account with a higher risk processing provider. Each situation is assessed on a case by case basis depending on the merchant’s location, the nature and volume of expected transactions, and the merchant compliance status.

Being able to provide payment processing services does not mean a provider automatically endorses the merchant business.

WebPays acquiring services should be considered along with other available acquiring services. Consider support for payment methods, transactions limits, and the costs charged for the various payment methods.

What to discuss with WebPays:

• Eligibility for your specific industry and business location.
• Card processing and payment gateway integration requirements.
• International payment acceptance and currency support.
• Fraud monitoring, chargeback procedures and transaction controls.

For businesses searching for a high risk payment gateway UK solution, the important question is whether the provider can support the actual risk profile of the business under clearly defined commercial and compliance conditions.

Paycly

Paycly is another payment service option that merchants can review while evaluating their payment service provider. Merchants should review Paycly's offerings against their business requirements, the nature of the transactions, and the jurisdictions in which they operate.

Merchants should not review payment service providers based on broad, generic statements related to pricing and approval times. Merchants should request information about the payment methods supported, the acquiring banks, and the provider's application evaluation process.

Merchants should also request information about foreign currency transactions.

Questions to ask Paycly:

• Does the proposed solution support your business category?
• Which countries and payment methods are available?

Additionally, a business may require payment services to accept different currencies.

There are numerous charges, costs and other factors beyond control of the merchant which may adversely impact the net foreign currency settlement.

Points to review with inquid.net:

• Supported industries, countries and currencies.
• Available gateway and processing arrangements.

The size and type of a merchant business will dictate the best solution for them. Similarly, the geography and the merchants requirements will impact Worldpay’s appropriateness.

What to consider: Online and point-of-sale capabilities, integration with existing systems, pricing structure, contractual commitments and support arrangements.

Payment Gateway Comparison: Which Option Fits Your Business?

Note: Features, eligibility, pricing and settlement terms can vary by merchant agreement. Confirm current details directly with each provider before making a decision.

What Makes the Best Payment Gateway in the UK?

Customers want to see a list of the best payment gateway providers in uk. However, companies need to look beyond brand recognition to determine the best payment gateway provider for their company. The best place to start is by identifying the payment methods accepted by the company as well as the payment methods offered by the provider.

1. Transaction fees and the total cost

transaction fees will vary based on the agreement and other fees charged by the payment gateway provider.

Additionally, transaction fees can vary based on the payment type used. As such, it is important to understand the payment types offered by the provider and how customers will transact on the company’s website.

2. Payment methods and checkout experience

Customers may prefer debit cards, credit cards, digital wallets or bank-based payment options. A gateway that supports the methods your customers actually use can make checkout more convenient.

Check whether the provider supports the payment methods needed in each target country. Also examine mobile usability, payment errors and the number of steps required to complete a purchase.

3. International payments and currencies

Cross-border sales can introduce foreign-exchange charges, additional processing fees and different settlement arrangements.

Settlement can happen in various forms and based on the payment type used. For international payment settlement, understand what currency the customer is paying in, what currency the company is receiving payment in, how the payment is settled, and what the payment gateway provider charges for the transaction.

4. Fraud prevention and authentication

Security should be part of the evaluation from the beginning. Look for appropriate encryption, access controls, fraud screening, transaction monitoring and support for applicable authentication requirements.

The exact security features available depend on the gateway and its wider processing arrangement. Merchants should understand which controls are included and which require separate services.

5. Settlement speed and cash flow

A successful payment does not necessarily mean the money will reach your bank account immediately. Settlement schedules can depend on the provider, acquiring bank, payment method, business risk assessment and transaction review.

Ask about standard payout timing, weekends and bank holidays, reserve requirements, delayed settlements and the circumstances in which funds may be held.

6. Integration and customer support

Check whether the gateway integrates with your eCommerce platform, accounting software or internal order management system. API documentation, testing environments and technical support can be particularly important for businesses with custom checkout requirements.

Before committing, clarify how support requests are handled and what assistance is available if transactions fail or settlement is delayed.

Choosing a High Risk Payment Gateway UK Merchants Can Use

Some businesses are considered ‘high risk’ due to a number of factors, including the nature of their product or service, what country their business is located in, the volume of transactions and the rates of chargebacks or disputes their business experiences.

Businesses such as Forex or gambling businesses can be considered high risk. So too can subscription, travel and other business models. Whether a given business model is considered high risk is largely determined by the underwriting policies of the payment processor.

When UK merchants are searching for a high risk payment gateway, it is important they consider the terms of the payment gateway and processor.

Understand the underwriting process

Providers may request company registration documents, director identification, beneficial ownership information, licences where applicable, website terms, refund policies, processing history and bank statements.

They may also ask about average transaction values, monthly turnover, customer locations and expected chargeback levels. Supplying consistent and accurate information helps the provider assess the application.

Review reserves and settlement conditions

Some merchant agreements include rolling reserves, delayed payouts or other risk controls. These can affect working capital, even when the quoted processing fee appears competitive.

Ask how any reserve is calculated, how long funds are retained, what triggers additional restrictions and when withheld balances are released.

Examine chargeback and fraud procedures

Chargebacks can reduce revenue and increase operational costs. A useful provider should explain its dispute process, transaction monitoring capabilities and available tools for responding to suspicious activity.

Merchants should also maintain clear billing descriptions, accessible cancellation procedures and evidence of customer consent where relevant.

Confirm that the service matches your business

A provider that accepts one high-risk category may not accept another. Approval for one country or legal entity does not necessarily establish eligibility for every market in which a merchant operates.

Before signing, obtain written confirmation of the approved business activity, permitted markets, payment methods, fees and settlement conditions.

How to Set Up a Payment Gateway

The onboarding process varies between providers, but most merchants can prepare by following these steps.

• Define your requirements - List your sales countries, payment methods, currencies, average order value and expected monthly turnover.
• Prepare your documentation - Gather company records, ownership information, bank details, website policies and any required industry licences.
• Compare suitable providers - Request pricing and confirm eligibility before investing heavily in an integration.
• Integrate the gateway - Use an available plugin or API and configure payment notifications, refunds and order reconciliation.
• Test the payment flow - Check successful payments, declines, authentication, refunds and error handling in a test environment.
• Launch and monitor - Review approval rates, failed transactions, chargebacks, settlement reports and the overall checkout experience.

A successful launch is only the beginning. Regular monitoring helps identify payment issues before they create larger problems for customers or cash flow.

Why Consider WebPays for Payment Processing?

Businesses with specialised payment requirements may need a more tailored assessment than a standard online checkout package provides. WebPays is worth investigating if your business needs a payment solution for a higher-risk category or requires a discussion about its processing requirements.

The important consideration is whether the proposed arrangement fits your business, rather than whether a provider makes broad claims about approvals or pricing.

When contacting WebPays, explain your industry, registered business location, target markets, estimated monthly volume and average transaction value. Ask for details of the available payment methods, integration options, fees, reserves and payout schedule.

You should also confirm the contractual entity providing the service and the relevant acquiring or processing arrangements. Where regulatory authorisation is required, verify the appropriate details independently. Explore WebPays

A clear proposal gives you a practical basis for deciding whether the service is suitable and comparing it with other payment gateway companies.

Final Thoughts

Picking a payment gateway is not just a checkout decision. It shapes how your whole business runs. Start with the basics: does the provider support the channels where your customers actually pay you? And will they give you room to negotiate settlement terms that work for your business?

It is also worth looking at the other side of the deal. Read the underwriting conditions carefully before you commit, and be honest about whether your cash flow and liquidity can handle them.

If you’re building a shortlist, WebPays, Stripe, PayPal, Paycly, BoxChrge, inquid.net, and WorldPay are good places to start. Judge them on the services they deliver, not on what their marketing says.
