How old are you and your partner? Do either of you smoke?
What is the rebuild cost of the house? If you don't know that, what size is the house? Where is it? How old is it? Is it standard construction? What value contents do you need insured? Are there any valuable items that you need covered (like engagment rings etc)?
You probably won't want to give out that much info but the price of the insurance you need depends on that.
For example my life insurance is for myself and my partner, both 25, non smokers,290k over 35 years, non decreasing = €23 per month
House insurance is 260k buildings, 45k contents, based in the west, rural area, new build, including accidental damage = €300 per annum.
This is all variable depending on the questions above so your best bet is to call around or go to a broker.
BTW, I work in a brokers so mine is probably a bit cheaper than the average. Staff discounts, no broker fee etc.....
