Consumer watchdog Which? has filed a ‘super complaint’ to the Office for Fair Trading about companies charging unjustifiably high surcharges to debit or credit card transactions.

Transaction charges typically cost 20p, yet numerous businesses charge up to £25.

Two areas Which? Would like the OFT to investigate are transparency- have consumers been informed about the surcharge; and proportionality- is the charge appropriate to the cost of the transaction.

The OFT will now consider the issues raised in the super-complaint in order to establish whether any element, or combination of elements, in the relevant markets is or appears to be significantly harming the interests of consumers. It will publish a response to the super-complaint within 90 days.
