I keep basic supplies at a number of locations.

At a friends house, about a mile away from home, useful in case of some local disaster such a chemical spill, riot or bomb.
These supplies include clothing, shoes, food, water, blankets, FAK, a little cash, chlorine tablets,flashlights, radio, lantern, batteries, a large knife and a multi tool.
These supplies are stored in two rentacrates in the roof space as the friends home is vulnerable to flooding, but otherwise low risk.
In return I look after almost identical supplies in my home for said friend.
We therefore each have double supplies if the other party does not need theires.

At my Mothers home, 200 miles away I keep very extensive stocks of food, water, clothing, blankets, tools, footwear,batteries and many other supplies.
These supplies are as much for surving any long term deppresion/economic crash as for sudden disaster.

At work in central London I keep food for a week or two, clothing, bottled water, batteries, radio, a little cash, and tools of my trade which would also be useful in a survival situation.
As the building engineer I believe that in a real emergency I could shelter in place and supplement my supplies in various ways.
I have a large UPS of my own at work that will supply PC, broadband modem, cellphone charger, radio charger, desk lamp etc for many hours.

Batteries in all emergency kits and supplies are swopped out at the end of every November.
This date is chosen in order that the old but probably still servicable batteries may be used in Christmas lights, kids toys etc.
