The Interchange Fee Regulation (IFR) has brought a number of changes to the way card schemes (such as Mastercard and Visa) operate, most notably by introducing a cap on certain interchange fees applicable to payment cards.
This page aims to provide merchants and retailers that rely on card payments, with information on how the IFR impacts their business.
When a customer makes a payment
In most cases, when someone makes a card payment to you as a merchant, your bank (known as an acquirer) pays an interchange fee to your customer’s bank (known as an issuer). This does not apply to American Express cards. Interchange fees usually form part of the merchant service charge (MSC) that you pay your bank for its services.
Following EU Withdrawal, the UK IFR caps interchange fees on consumer debit and credit card transactions where you, the acquirer and the issuer are all located within the UK. Where the caps apply, they currently limit interchange fees to 0.2% of the value of a transaction for consumer debit cards (including prepaid cards), and 0.3% for consumer credit cards. The caps also apply to certain fees relating to some American Express card transactions. The interchange fee caps took effect from 9 December 2015.
Our guidance on our approach to monitoring and enforcing the IFR provides more information on the transactions that are not covered by the interchange fee caps.

Since 13 January 2018, you’re not allowed to charge customers extra if they pay using certain payment methods, including a card that is capped by the IFR. There are limited circumstances in which you may still surcharge a customer. The Department for Business, Energy and Industrial Strategy has published guidance on surcharging rules. You risk being reported to the local trading standards office if you do not comply with rules on surcharging.
Merchant Service Charges (MSC)
The MSC that you, as a merchant, pay your bank is made up of several components. While the IFR caps certain interchange fees, it does not cap the MSC.
If you want to reduce the charges you pay, speak to your bank or consider shopping around.
The IFR is not just about card fee caps
In addition to the interchange fee caps, the IFR also introduced a number of business rules. These include requirements for an acquirer bank to give their customers (i.e., merchants) information about the costs of accepting different brands and categories of cards (credit, debit, prepaid and commercial). This should help you negotiate a better deal with your bank.
