How to Choose Payment Gateway Software in the United Kingdom
In the United Kingdom, selecting Payment Gateway Software is critical for ensuring compliance with financial regulations and providing a seamless transaction experience for your customers. The Financial Conduct Authority (FCA) oversees payment services, requiring businesses to adhere to the Payment Services Regulations 2017 and the Electronic Money Regulations 2011. Your business must also comply with the General Data Protection Regulation (GDPR) regarding customer data protection. The core challenge you face is navigating these regulatory requirements while ensuring that your payment processing is efficient and secure. Failure to comply can lead to significant penalties, including fines from the FCA and reputational damage. Understanding these regulations will empower you to make informed decisions when selecting the right software for your business needs.
Asking a payment gateway software vendor whether it holds Cyber Essentials is a short question with a checkable answer: the NCSC scheme covers five named technical controls and is increasingly a condition of bidding for work.1 Major players like PayPal and Stripe dominate the market, but local providers are also gaining traction.
Key Regulations
Payment Services Regulations 2017
This regulation mandates that all payment service providers in the UK must be authorized by the Financial Conduct Authority (FCA).

Non-compliance can result in penalties up to £500,000 and potential criminal charges for operating without authorization.
Electronic Money Regulations 2011
Under these regulations, any business issuing electronic money must be authorized by the FCA.

General Data Protection Regulation (GDPR)
GDPR requires that your payment processing software ensures the protection of personal data. This includes implementing data encryption and secure storage practices. Non-compliance can result in fines of up to €20 million or 4% of your annual global turnover, whichever is higher.
PCI DSS (Payment Card Industry Data Security Standard)
Compliance with PCI DSS is mandatory for any business that processes credit card transactions. Your software must meet specific security standards, including encryption and secure data storage. Non-compliance can lead to fines from payment card networks and increased liability for data breaches.
Anti-Money Laundering (AML) Regulations
Under the Proceeds of Crime Act 2002 and the Money Laundering Regulations 2017, your payment gateway must include features for customer due diligence and transaction monitoring. Failure to comply can result in penalties of up to £1 million and potential criminal charges.

This act requires that your payment processing software provides clear information about payment terms and conditions. It must also facilitate refunds and chargebacks in compliance with consumer rights. Non-compliance can lead to legal disputes and reputational damage.
What to Look For
FCA authorization verification
Your payment gateway software must be able to verify that the provider is authorized by the FCA. This is crucial for ensuring that your business operates within legal parameters. Before purchasing, confirm with vendors that they can provide proof of FCA authorization.
GDPR-compliant data handling
The software must include features that ensure compliance with GDPR, such as data encryption and user consent management. This is essential for protecting customer data and avoiding hefty fines. Verify that the vendor can demonstrate their compliance measures.
PCI DSS compliance support
Your payment gateway must support PCI DSS compliance by providing secure transaction processing and data storage solutions. This is vital for protecting cardholder information. Check that the vendor can provide documentation of their PCI DSS compliance.
Transaction monitoring tools
The software should include tools for monitoring transactions to comply with AML regulations. This feature is necessary for detecting suspicious activities and fulfilling legal obligations. Ensure that the vendor can explain how their monitoring tools work.
Refund and chargeback management
Your payment gateway must facilitate easy processing of refunds and chargebacks in line with the Consumer Rights Act 2015. This is important for maintaining customer trust and compliance. Confirm that the vendor's software has these capabilities.
Secure customer authentication
The software should support strong customer authentication methods to comply with the Payment Services Regulations 2017. This feature is critical for preventing fraud and ensuring secure transactions. Ask vendors how their software implements these authentication measures.
Common mistake: Many UK businesses purchase payment gateway software that lacks FCA authorization, leading to severe legal consequences. Operating without FCA compliance can result in fines and the inability to process payments legally. Always verify the vendor's FCA authorization status before finalizing any purchase to avoid costly mistakes.
