Got a great deal last year with LA Brokers. Free for first year. Hibernian is the provider. Usually a comparison in Best Buys etc. Useful as a guide. Try Insure.ie for a quote. Also 123.ie.
LABrokers gave me costings for 3 providers, Hibernian, Eagle Star & Friends First. Funnily enough, the two providers which had the 50c for first year offer were dearer in the long run than Friends First.
