From this morning, new rules being introduced by the Central Bank mean that insurers must now provide their customers with more information when renewing their motor insurance policies.
It says it'll give greater transparency to customers to help them to make informed decisions when purchasing insurance.
Companies must tell their customers the premium they paid the previous year, in clear writing, on the same page as their new quote.
They'll also have to give a quote for each policy available, such as comprehensive, third party fire and theft cover, or third party only.
The renewal period is being extended from 15 to 20 days to allow policyholders more time to shop around.
That applies not only to car insurance but also to health, damage to property and general liability insurance.
