Payment Gateway Fees UK: What Do Gateways Cost?

Payment gateway fees can include transaction charges, fixed fees, platform costs and additional charges depending on the provider and payment setup.

Gateway fees versus processing fees

The terms are often used interchangeably, but a business may have separate gateway and processing arrangements. All-in-one providers can combine several services into one commercial relationship.

Costs to put on one comparison sheet

Do not compare percentage rates in isolation

Two providers with different percentage-plus-fixed pricing can reverse their cost position at different transaction sizes. Use your own sales data and calculate a realistic monthly total.
