As has been pointed out it is impossible to say where you would get a good deal as its down to your house and content value, condition, location, security/fire prevention features, personal items, outdoor sheds, accidental damage, etc etc.
I can tell you that I have my house and contents insured with FBD - cost €180 about 4 months ago. At the time I sought a quotation from the local brokers who I know well and they told me the cheapest they could find for me was €355 for the same type of cover - quite a difference
