The UK Payment Systems Regulator (PSR) has published an invitation to comment on a revised draft questionnaire for a proposed survey of UK merchants as part of its review of cross border interchange fee remedies. The survey will gather data on merchants' costs of processing online payments from the EEA using cards and certain alternative payment methods, with the results feeding into a Merchant Indifference Test to inform the appropriate level of cross border interchange fees. The PSR has updated the questionnaire following responses to the PSR's October 2025 consultation on the methodology for developing a price cap remedy. It decided to include questions on SEPA based bank transfer methods, PayPal and Klarna's "Pay in 30 days" product but proposes to exclude American Express. The deadline for comments is 5.00 pm on 5 March, noting that further revisions may be made ahead of fieldwork.
