I was in the same boat.I was originally with 123.ie for a number of years but in 2009 I got a quote that made my eyes water.I then went looking for some one cheaper. Getcover.ie were the cheapest I could find on the web in 2009 but this year they wrote saying they were no longer offering Landlord Insurnace due to excessive numbers of claims from Landlords.They did offer to put me in touch with a broker who gave an outrageous quote. Double what I paid the previous year.I went to 123.ie but they were equally as dear. A friend of mine who has a number of properties recommended Allianz.They where cheaper than Getcover had been for us in 2009.
What I liked about Getcover was you could do it all over the web.Allianz is a bit messier.You get a quote on the web.They then post out a proposal which you have to sign and return.Its not a big deal especially considering the money I saved but I don't understand why they don't go the whole hog and let you fill out the form online like Getcover.Disclaimer: I have no association with Allianz or any insurance company.
I hate ringing Insurnace companies so I tend to search for quotes on the web which give you an instant quote.None of this we will contact you with a quote business for me.I think that is the reason I have overlooked Allianz in the past.
