Apparently the 'average temperature' for last December was the coldest
for a hundred years, at minus 1 deg C instead of an expected plus 4
deg C.

As we are told that turning down one's central heating by 1 deg C can
save 10 percent of heating costs, then December's low must have
ratcheted up the energy bill by some fair amount, possibly 50 percent
at a first guess.

This is our first December in this house, so I have no idea what might
have been a normal figure to compare to, but the gas meter readings
for that month say we used 3600 kWh, for a four-bed detached house on
the edge of some fields.

I'd be interested in any figures people might have for their December
energy consumption, compared to the previous December.
