Visa & Mastercard Interchange Fees Explained for UK Businesses
A breakdown of how interchange fees work, recent changes from card networks, and strategies to minimise your payment processing costs.
What Are Interchange Fees?
Interchange fees are the costs that merchants pay to card-issuing banks every time a customer pays by card. They're set by card networks like Visa and Mastercard and form the largest component of your payment processing costs.
How Interchange Works
When a customer pays £100 with their Visa debit card:
- The card network (Visa) facilitates the transaction
- The issuing bank (customer's bank) receives the interchange fee
- The acquiring bank (your bank) receives a small margin
- You, the merchant, pay all these fees through your payment processor
Current UK Interchange Rates

Strategies to Reduce Interchange Costs

- Review your merchant category code — ensure you're classified correctly
Recent Changes
Visa and Mastercard adjusted their UK-EU interchange rates post-Brexit, significantly increasing costs for cross-border transactions. This particularly affects e-commerce businesses selling to EU customers.
