We're on bottled gas. 4 bottles, replaced two at a time when they run
empty. At the height of a "normal" winter, we replace a pair every 2
to 3 weeks. During December they were only lasting 8 days. In December
we spent £400 on gas. Hence my questions in another thread about
woodburning stoves ;-)

You need a ground source heat pump, some can get grants if they are elderly,
disabled, etc.
