I'm thinking a little more "outside the square" here, taking your bare essentials, and adding in "somewhat" essential items.

Mobile phone plan/cost/service.
Car servicing/repair
Gas to home (you mentioned electricity, missed gas)
Appliance repair & servicing

Don't also forget - getting the necessities in life is a good thing, of course, but people like to reward themselves too... I don't quite know what your planning in terms of this site, but other things to consider:

Wine/liquor
Restaurants/home delivered meals
Cinema or other outing

Look forward to seeing the results of your thinking!
