Visa is changing its interchange rates for UK Visa debit transactions again in September 2016. The current interchange caps of £0.50 for secure and £0.75 for non-secure consumer transactions, and £1.00 for secure and £1.50 for non-secure business transactions, will be removed. Instead, interchange for all UK Visa debit transactions will be a flat rate of 0.20% of the transaction value, in line with the rest of Europe. Merchants with average transaction values over £250 are most likely to see significant increases in their costs.
