Can't see anything outrageous there and short of shopping around for better deals on any of the individual expenses I can't see much room for savings. A few specific suggestions:
Car Insurance - 100
I presume that you shop around annually for the best deal?
Phone - 30
If you make mostly off-peak local, national or
UK calls then perhaps something like
UTV Talk (all such calls are free) or
eircom talktime etc. might save you a few bob. Mind you might only yield c. €5 p.m. savings... Make sure that you're not paying equipment as opposed to line rental unnecessarily (c. €2.50 p.m.).
Food - 200
May be scope for savings here by shopping in
Aldi/Lidl/Dunnes rather than more expensive stores which may be more convenient but cost more.
Health Insurance - 22.60
Make sure that you are getting the 10% group discount even if it means, say, sticking a tenner in the local
Credit Union so you can quote them as your group scheme to avail of it. Shop around. I've generally found
BUPA cheaper (and better in terms of service) than
VHI for equivalent cover.
Vivas may offer even better value for certain schemes.
Mortgage - 585 (without taking TRS into account which hasn't been applied yet).
Does this include mortgage protection life assurance and home insurance? If you bought these from the mortgage lender then chances are you can get a better deal elsewhere. Shop around. You can apply for mortgage protection life assurance [broken link removed] if you haven't already applied for it.
You don't mention other expenses such as mobile phone, waste disposal charges etc. Are you sure that the list is almost comprehensive.
