If you work in an office do you wear your work shoes on the commute? Swap to runners, carry the shoes (or leave them under the desk) - one year I spent €65 on re-heeling boots.
Since I started wearing runners in, no shoemending needed at all.
Duvets - I spent €50 on getting the duvets dry cleaned as they were looking a bit grubby. I discovered this year that a thin duvet fits in the washing machine (I have those two part summer/winter ones) - no need for dry cleaning.
Are you changing your car? Go for same size or smaller engine in diesel if you have petrol at the moment. Saving of about 40% on fuel (really, I went from €250 per month to €165). Also newer cars are more efficient (I went from 2002 Polo to 2007 Fiesta).
Am doing the fleece curtain lining thing this year. Also I have a big curtain and a €5 pole from IKEA to put up over the front door (it's 35 yrs old and a bit drafty but I can't afford to replace it). I'll also be insulating the attic (myself) in a couple of weeks when I get a loft ladder installed. My brother did it himself on his house, cost €200, they reckon they saved it in heating costs in one year.
Put your heating on timer NOT putting it on when you feel chilly. If I put it on manually in the evening, it ends up on for hours, as the timer is in the kitchen and we are in the sitting room with the TV. Make sure that you have nice throws in the sitting room so that if you get a bit cold sitting still watching the box, you cuddle up under the throw rather than putting the heating on again. (I make quilts so I have a nice one on the sofa that looks lovely when not in use for warmth). If it's not a nice throw/quilt it will annoy you, you will put it somewhere out of sight, and then forget about using it.
TV - freesat? about €100 for dish and decoder, maybe another €50 to get it attached to your house. Only TV cost that I have now is the licence.
Netflix - you can have 5 devices on one account. Can you share with someone (€7 pm) - I share with my sister (prob not allowed officially though).
Totally agree with packed lunches. I'm a v plain eater for lunch (comfort!) - I freeze bagels at home, and bring in one a day - I keep cheese triangles in the work freezer. Prob costs me under €1 a day. If I want something more substantial, I make homemade soup.
Work deals - in med/big companies with their own intranet, always check it for deals/recommendations for tradespeople/buy and sell ads. I have a fuel card (as we have a sales staff whose petrol is paid for, the petrol company offered it to all staff). I pay it once a month, a direct debit after payday. Petrol costs same as at pump, but technically there is about 4 weeks free credit. Plus if the car is empty the day before payday, you don't have to worry.
Does your/your DHs company have any savings/holiday offer, where they take X pm out of salary, and give it back to you when you put in a req for it? Great way of saving - sometimes they give it to you after 4 mths of a 12 mth repayment period is over, with no interest - basically a free loan. In our co, a lot of people use it to pay off credit cards.
