Credit card processing is a huge part of modern commerce, especially in the increasingly cashless landscape. However, the associated costs can significantly impact a company’s profitability. Potential changes are on the horizon, both domestically and internationally. It’s important for businesses to understand the ins and outs of these fees and how to manage them effectively. Here is your guide to understanding credit card processing costs, potential changes and key strategies for UK businesses.
Currently...
Credit card processing fees are not a single charge; they consist of various components.
In-Person Transactions: For businesses with a physical presence, in-person transactions generally incur fees ranging from 0.7% to 3.4% for credit cards, and slightly lower for debit cards, at 0.4% to 1.7%.
Online Transactions: Due to the higher risk of fraud, online or "card-not-present" transactions carry higher fees, typically between 2.25% and 2.5%.
The Fee Breakdown:
Interchange Fees: These are the largest portion of the fees, paid to the card-issuing bank (e.g., Barclays, HSBC). They vary widely based on card type (rewards cards often have higher interchange fees) and transaction method, ranging from 1.29% to 2.8%.
Assessment Fees: These are smaller fees charged by the card networks (Visa, Mastercard, American Express) and typically range from 0.13% to 0.16% per transaction.
Processor Markups: This is where payment processors (e.g., Worldpay, Square, Stripe) make their profit. These are variable and include monthly account fees, per-transaction costs, and batch processing fees.
Additional Costs: Beyond the per-transaction fees, businesses should be aware of:
Monthly Service Charges: These can range from £5 to £25.
PCI Compliance Fees: Ensuring secure processing to protect customer data can cost £2 to £20 per month.
Chargeback Fees: When a customer disputes a transaction, businesses face fees of around £15 per incident.
American Express: American Express often operates on a different model, with higher fees, often ranging from 1.43% to 3.3%.
What to look out for: US Policy and Global Trends
The global credit card processing landscape is potentially facing significant changes, driven primarily by developments in the United States. While the UK has its own regulatory framework, shifts in the US market can have ripple effects.
Credit Card Interest Rate Cap: A proposed 10% cap on credit card interest rates (significantly lower than the current US average) could reduce issuer profitability, potentially leading to reduced credit access and fewer rewards programs.
Credit Card Competition Act: This bipartisan legislation aims to break the perceived Visa/Mastercard duopoly by requiring at least two network options for each transaction, potentially lowering processing fees for merchants.
CFPB Oversight Changes: A less aggressive Consumer Financial Protection Bureau (CFPB) could create a more relaxed regulatory environment, affecting how credit card companies structure fees.
Focus on "Junk Fees": The proposed interest rate cap aligns with a broader crackdown on "junk fees," potentially impacting various credit card processing fees.
Reciprocal Tariffs: These could indirectly affect the cost structure of international transactions and cross-border processing fees.
Global Ripple Effects:
Changes in US interchange fee policies could have indirect consequences for international markets. Reduced profitability for global card networks like Visa and Mastercard might lead to adjustments in fee structures in other regions, including the UK. UK merchants might benefit from lower cross-border transaction fees if similar pressure is applied locally.
In the UK...
The UK has its own rules, the Payment Services Regulator (PSR), actively addressing credit card processing costs.
PSR Proposals: The PSR is considering reintroducing caps on cross-border interchange fees between the UK and EEA countries. These fees have risen significantly since Brexit (from 0.2%-0.3% to 1.15%-1.5%). A proposed cap, aligned with pre-Brexit levels, could save UK businesses £150-200 million annually.
Market Dominance: Visa and Mastercard dominate the UK payments market (over 99% of card transactions), giving merchants limited negotiating power.
Impact of Caps: While a cap on interchange fees would likely reduce merchant costs, past experience suggests that these savings might not fully translate into lower consumer prices.
Implications for Businesses and Consumers
Businesses: Lower interchange fees could reduce operational costs. Online businesses, facing higher fraud risks, should explore alternative payment methods like account-to-account transfers to mitigate expenses.
Consumers: Regulatory changes in both the US and UK could lead to reduced rewards programs or stricter credit approval criteria. If Trump's policies indirectly influence global markets, UK consumers might see shifts in credit availability or merchant pricing strategies.
Open Banking
Open banking is an exciting development in financial services. This allows secure sharing of financial data between banks and third-party providers. This offers several advantages, including direct payments, where customers can make payments directly from their bank accounts, potentially avoiding traditional credit card processing fees. Open banking means transactions are faster than traditional card payments. It also offers enhanced security, open banking can reduce fraud risks associated with card-not-present transactions. Open banking could be an effective alternative to traditional credit cards for many businesses.

Strategies for Negotiating Lower Credit Card Processing Fees
Understand Your Current Fees: Thoroughly review your current processing statements. Identify all charges and understand your effective rate.
Research and Compare Processors: Don't be afraid to shop around. Get quotes from multiple processors and compare their rates and services.
Highlight Your Business Value: If you have a high transaction volume, a long history, and a low chargeback rate, emphasize these points during negotiations. A strong track record makes you a more desirable customer.
Be Prepared with Specific Details: Don't just ask for "lower fees." Identify specific fees you want to negotiate (e.g., processor markup, monthly fees) and support your requests with data and research.
Consider Level 2 and 3 Data: For B2B transactions, providing more detailed transaction data (Level 2 and 3) can qualify for lower interchange rates.
Negotiate Annually: Don't treat your processing agreement as a one-time deal. Review it annually and renegotiate as needed.
Bundle Services: If you use other services from your processor (e.g., POS system, online gateway), leverage this to negotiate a better overall package.
Finally...
The world of credit card processing fees is dynamic and multifaceted. By understanding the current fee structure, staying informed about potential regulatory changes, and proactively negotiating with processors, UK businesses can effectively manage these costs and protect their profitability. The potential for significant shifts in the coming years makes vigilance and adaptability crucial for success.
