Americans probably have valid reasons to prepare, if anyone was going to get hit by an earthquake, tornado or bio-weapon it's them.
In the UK the most we can expect is a national strike cutting food and fuel deliveries, possible extended power cuts and maybe a few days of snow. Probably losing my job is a big issue too.
I gear my preps around that, I have a generator and spare fuel, solar panel and an invertor running off a deep cycle battery, paraffin/gas/LED lamps and probably basic food for a month. I don't envisage the water company failing to pump water so stored garden water will suffice. Internet can be dial up, cable or 3G.
I'd like a portable gas heater and a solar water heater, and I intend to make the house more secure, but that's it really.
