Three-quarters of people in Ireland are now aware of their consumer rights, according to a survey commissioned by the National Consumer Agency.
The organisation says the figure represents an improvement from the 66% of respondents who knew their rights during a similar survey two years ago.
Despite this, the number of consumers who are willing to make a complaint has fallen from 79% to 69%.
Commenting on the results, Ann Fitzgerald, Chief Executive of the National Consumer Agency said: "Whilst these consumer confidence figures are encouraging, there is an important distinction between understanding your rights and acting on them.
"Our statistics show that since 2007 our propensity to actually complain when dissatisfied has fallen back from almost 8 in 10 to just under 7 in 10.
"We would urge people who might be feeling uncertain or vulnerable when it comes to getting satisfaction with a consumer complaint to find out about their rights and to speak up if they are unhappy with a product or a service they have purchased."
