I have a propane bottle, kept outdoors, that feeds a gas hob and Electrolux
refrigerator. In sub-zero temperatures I get no pressure indoors, but am
unsure whether this is due to the regulator having some water in it, which
freezes and sticks it shut, or water in the gas pipe itself (which should be
impossible, if the bottles only contain dry propane).

Has anyone had experience of this?

Yes. It's not due to water at all, it's a property of the pressurised
propane gas. Propane, although "better" than butane, will not change
state from the liquid phase to the gas phase at very low temperatures.
Butane refuses to "work" at anything below about 4°C.
