Almost 1,200 drivers were refused a quote for car insurance by three or more insurers last year, making it the highest number of multiple refusals on record.
New data released by Insurance Ireland showed that 1,164 drivers seeking cover for their vehicles were dealt with under the Declined Cases Agreement in 2015.
The agreement makes sure that anyone who was denied a quote by three different firms must be offered cover on the fourth attempt.
In comparison to the number of applications made under the Declined Cases Agreement in 2012, there has been a six fold increase. In 2012 only 178 requests from drivers were received.
According to another report by the Motor Insurers Bureau of Ireland, The average cost of car insurance is estimated to have increased by over 70% since 2013, with some premiums rising at a much higher rate.
Irish drivers are being urged to shop around more - in order to get better deals on car insurance.
