Standing charges

There was no mains gas where the little house down west was and the boiler ran on oil. Cost a fortune to fill the tank BUT there were no standing charges for oil, unlike gas, when you have to pay them however little you use.

I never thought of that veggie! Same for wood for the woodburner I suppose,no standing charge there either.

Same could be said for bottled gas,solar power, wind power, hydro power from a steam? although the setup costs would be high in those instances.
