Danish insurer Qudos, which has around 50,000 Irish-based customers, has said it will not be paying out on any claims at present as the company has gone into liquidation.
Qudos, which filed for liquidation in Denmark on 27 November, would mostly have sold motor insurance policies to customers here via agents and brokers.
Although the company said its insurance policies are still valid, it will not pay out on any claims "at the moment" and expects to give more detail on the payment of outstanding claims within the next two weeks.
The Central Bank has said it "strongly recommends, based on the uncertainty around the payment of claims, that affected customers contact their insurance broker to arrange alternative insurance cover".
