This is not a pre Armageddon check list, just a few sensible precautions. Every winter we seem to read about a few thousand houses somewhere, being without electricity for days/weeks.
So, three bottle gas heaters, an LPG hob, plenty of candles and matches, torches and batteries, an open fire and a tonne of coal, plenty of kindling and logs. Even an analogue phone.
For lighting, I do have a brass oil lamp complete with wick, glass shade and chimney, which I assume is designed to run on paraffin? Would it be OK to use central heating oil, there being a tank full in the garden?
