Pay.UK is a UK retail payments authority, responsible for operating and managing key UK payment systems. It’s not a payment provider or bank itself but rather a regulated central infrastructure organisation that maintains the UK's critical payment schemes. Pay.UK imposes the rules for Bacs, Faster Payments, and the Image Clearing System for cheques (with Vocalink running services). It ensures secure, efficient, and reliable payment processing across the UK economy.
