Online shoppers are facing significant changes to their rights following Brexit, if they are buying from UK companies.
Research published today by the Competition and Consumer Protection Commission shows seven out of ten people in Ireland have bought from a UK-based retailer online in the past two years.
The CCPC surveyed shoppers and 40% of them said they had returned items to online UK sellers.
The commission will launch a campaign today to highlight how shoppers' rights could be affected.
When we buy something online from an EU-based retailer, if we change our mind, we are entitled to return it within a certain timeframe.
It is one of many rights under EU legislation which gives shoppers flexibility when they buy online.
When Brexit day comes, rights like this may not be guaranteed.
A quarter of people surveyed said they plan to make changes to their online shopping habits after Brexit, with a third saying they plan to buy more from EU countries.
Apart from losing some rights, buying from UK-based vendors could also mean more tax, like customs and excise duty and VAT.
Over the next six weeks a campaign informing consumers will be rolled out, and more information is available on ccpc.ie
Meanwhile, the banking industry here has advised Irish-based customers of UK-based banks to contact their financial institutions to check the status of their banking services in the event of a no-deal Brexit.
"If customers have not already heard from their bank, they should contact the bank directly as soon as possible," the Banking and Payments Federation of Ireland said.
The BPFI said that in the event of a no-deal Brexit some Ireland-based and other EU-based customers of UK banks could experience disruption to their banking service or potentially could see that service withdrawn.
It said such a situation could arise as a result of differing legislative and/or regulatory provisions applying in the UK and elsewhere in the EU.
