The only significant shortage that I have observed here in the UK is Propane. Has been in short supply, to varying degrees, for at least a year.

Propane is much less used here than in the USA, most households don't use it at all.
That however is no consolation for the minority of rural householders who do use this fuel.

I do not use propane normally but keep a couple of cylinders for emergencies, each cylinder contains 19 kilos of the fuel. Other sizes are available.

The largest portable cylinder is 47 kilos, and the smallest is 4.5 kilos.
For greater demands bulk tanks are available, these are fixed in place and filled from a road tanker. Not common but used by some rural homes and farms.
