Wouldn't really call it a survival kit but I've got 6 months of tinned food in the cupboards and enough whole wheat, milk powder, salt and honey to last a lot longer( got a hand crank grain mill) my gardens full of beg and I've got 2 hen. I only have all this stuff because im the worst cheapskate known to man.
As for cooking I have a camping style 2 burner stove and 2 good size gas canisters( 1 is still going after almost a years use) hay box.
Got drums for collecting water from my roof, if it didn't rain for a month id be fine.
I have no heating or electricity so I have no need to heat the house( as I write this im wearing 2 jumpers and I can see my breath lol) having no heating isn't a problem because I rarely sit down long enough to get cold. My house is so badly insulated it would be pointless heating it even if I wanted to
For protection I have a very big dog.
Plus the usual first aid kit, torch and spare batteries.
Though im a young guy who lives alone so my priorities are different, as long as it rains at least once a month, I dont even have to leave the house for at least a year.
