New nuclear bunker.

What changes can we make to our lives to deal with the economic and energy crises ahead? Have you already started making preparations? Got tips to share?

Stocks are fairly comprehensive, and include at least two means of achieving almost any desired result.
For example, safety matches AND lighters.
Several can openers AND Swiss army knives that incorporate can openers.
Cyalume light sticks AND battery torches/lanterns AND candles.
Chlorine tablets AND gravity water filters.
Two washing machines AND facilities for hand washing, AND large stocks of clothing.
Duplicated electric well pumps, AND a hand pump, AND a storage cistern, AND bottled water.

And remember that danger from fallout or other radiation is cumulative, so a brief excursion outside the shelter to fetch vital supplies MIGHT be an acceptable risk. A dose rate that would kill in a few days, might be acceptable for a few minutes.

I would be interested to know how the story of the construction of the bunker was, to use a New Labour term, spun.

Was it hidden, or a roof put over the site to hide from satellites, because you never know who is watching, or a story concocted that is was basement for a house?

It consists largely of an existing basement, reinforced for extra blast resistance. A few bits are new construction. A determined inspection of satellite images MIGHT reveal the work, but firstly a private bunker is not that interesting to a foreign power, and secondly large excavations are a frequent event for so many purposes that no likely enemy can monitor them all.

The only unusual feature is the water supply from a well within the shelter.

There are several emergency exits, blocked by piles of sand bags so no good for a quick exit, more a longer term plan in case the collapse of the house above prevents use of the ordinary entrance.

I would have never thought to have a double-pole-double-throw switch (I presume) short circuiting in the off position.
Light switches are of the SINGLE pole, double throw type. When the lamp is turned off, the negative side of the lamp remains connected to the earthed negative pole of the battery, but the positive side of the lamp is also connected to the negative pole of battery.
I saw no merit in disconnecting the lamp from the earthed side of the battery since an EMP event could then result in a damaging voltage between lamp and earth.

13 amp sockets on the generator supply are wired similarly. Un switched socket with switch adjacent, not built in. When off, the live pole of the socket is connected to the earthed neutral pole.
No changeover arrangements. Pairs of sockets one on each generator. Water heater has three elements, one on mains, one on each generator. No changeover except by manually altering the connections.
