Starting a stash at home, what items to buy?

[RuthieBabeee]

Back in the day we had a stash of 'flu food' inspired by the fear of SARS and swine flu worries years ago. We've moved house since then and we don't have any emergency stash anymore.

We have a little bit of space under the stairs that isn't being used so thought I'd put some things aside. I'd love some advice on what I should be storing.

To buy:
Candles
Matches and lighters
Bottled water
Tins of beans
Tinned potatoes
Tinned carrots
Tinned spaghetti
Chocolate bars

I've chosen those because all can be eaten hot or cold if needed, so if no power we wouldn't starve but would have some protein and carbs, plus the potatoes and carrots come in water.

Also considering :
Water purification tablets
Wind up radio (what should that be tuned to in an emergency?)
Wind up phone charger
First aid kit

Where do you look to buy these?

If you had £100 to spend on prepping (not including the food stash) what would you buy?

I've stocked lots of tins of rice pudding; long use up by date, we all love it, and it is a lovely source of instant sweet stodgy comfort food.

I also had a brainwave for our family(!), I cook a lot of enormous - 3 teen boys - chilli con carne, curries, bolognaise from scratch. So I've bought lots of these in tins which are cooked and can be eaten cold in shtf scenario, but I could also absorb them into my homemade chilli etc and just add the odd can to mix in if approaching the use by date.
