Andy Allen, UK ECC Director, said: "The increase in the number of consumers resorting to the ECC network is driven by a number of factors: an increasing knowledge among consumers of their rights; greater awareness of the ECC network; the increase in cross-border purchases and a general 'crisis' effect, with consumers seeking the best deal and the best service.
"Our aim is to help as many UK consumers as possible who encounter problems with a trader based in Europe, to achieve a resolution: a replacement, repair, refund or cancellation of their contract."
The centre also handles cases from European consumers who are having problems with UK traders. In 2013, these represented some 28% of the total number of complaints handled.
Overall, the EU network saw a rise in cases handled to more than 80,000, a rise of 11% on 2012 figures.
About a third of all complaints involved the transport sector. Air transport had the largest proportion (18.3%); but car rentals saw an ever-increasing number of complaints across the EU. Complaints about household equipment, purchase of tickets for sporting and cultural events and timeshare were also widely reported.
Around 15% of problems concerned the non-delivery of purchased goods or service with another 12% of complaints citing defects in purchases.
