Agree, no need to panic but gathering supplies and being aware is prudent.
I consider myself fairly well stocked up but have added some extra supplies.
Mainly propane, this fuel is much less used in the UK than in the USA.
Whilst times are normal I don't use any propane, but it is handy for breakdowns and emergencies.
I have purchased another two bottles each of 13 kilos contents. Existing stock was one full bottle and one half full.

I normally cook with electricity, but have a high capacity boiling ring for emergencies. Each 13 kilo cylinder would give about 50 hours operation of one burner.

I normally heat with wood in the main living room and electricity elsewhere, but have a portable propane heater for emergencies. One 13 kilo cylinder will give 50 hours heating.

I am well stocked with non perishable foods, but the main problem would be cooking. I can do limited cooking on the wood burning room heater, but propane is preferable.
