LPG is still an actual fuel, so should remain reasonably available if you can store it.

For example...
Most people can't though. The rules for tanks are quite strict, hence many people in built up areas without access to gas have to heat by electric or oil.
.. and those who don't want to be rodgered by Calor for the rest of their days too...
You will always be rodgered. Accept it, live with it, get over it, move on
My mum has to heat by a fikcin enormous great big 3 phase electric boiler. Hence, EDF/SSE/EON/whoever thoroughly rogers her on a monthly basis.
Little bro, in the same village, goes for oil instead. Whilst he has an enormous tank in order to buy in the cheaper summer months, it still needs a splash and dash in the winter, so he gets rogered by Gulf.
I see I'm paying £185 a month, so whichever bunch of knob jockeys I'm with this year is rogering me.
