wow, well done.
bills you need to consider.
esb: depends on size of house how much you use. we use about €100 a month for 2 adults/1 child.
gas: again about €100 a month for us.
tv: you'll need a tv license which is €160 approx for the year. If you want sky/chorus you're looking at about €30 for a fairly standard package.
contents insurance is probably all you'll need for renting. 2 years ago we paid about €200 i think. think it was with hibernian.
Food is another big one. This is probably the hardest one to judge, for us it's about €80 a week but you could probably do it for less if it's just two of you.
other things to consider are telephone, broadband.
Can't really answer re the savings. Just bought a house recently so savings are a thing of the past!!!!
Good luck, enjoy your new home
