Coldest December for 100 years - how did it affect your energy consumption?

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.

We used approx 1200kWh for december, that's for a mid terrace using gas for cooking and heating. We do however have an electric heater in the living room which we only use for short periods and we went away for a week. This is up approx +25% on november.

I'm too scared to take a gas meter reading. I suspect I'll be rogered rather thoroughly when my direct debit is next reviewed.

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.

Dec' 2009 was 3017 kWh. Curiously our electricity usage was 12% less than last December.

House was empty for about 8 days hence you can see "call for heat" time when heating wasn't on, which is the frost protection kicking in. Also, there are periods when house was empty when heating came fully on, as the frost protection in the house was not keeping the attic above freezing.

We used 30% more gas (for CH & HW)compared with December '09 - but 13.5% *less* electricity.
The increase in gas usage is what I would expect because the heating was on for a lot longer and we also supplemented it with the gas fire (which is less efficient) quite a lot. I can't explain the *reduction* in electricity usage - but other people seem to have reported the same thing. Curious!

Turned off the lights and went to bed early? Having bought a new duvet in September I have probably saved quite a lot of gas by not having the heating on overnight at all this winter.
Not sure of my gas consumption so far this year as I only tale a reading and calculate a comparison when the quarterly bill arrives (Nov-Feb)

Snow is very reflective - less lighting? If the gas consumption is something like 10000kWh and the electricity consumption is 400kWh, then it's insignificant anyway.

we went for the bunker option, and turned the heating way down, using wood and occasional selective bursts of CH to heat specific rooms when needed. We actually have used LESS.

Don't forget we had a pretty cold spell in December 2009 too, so figures may not be all that different.

Usage 2010 Gas 2706 kWh, electricity 554 kWh, total 3260 kWh.
Comparison with 2009 Gas 126%, electricity 108%, total 122%.
Without fairly modest 35 kWh of solar generation, the electricity would have been at 112%, and overall 124%.

Just as a FYI (and I don't have 2009 data unfortunately) December averaged at -12C over here, and our usage was about 4700kWH - around 2000kWH of that on the electric heat and the rest via the propane furnace.

Burning oil but I have taken weekly tank level readings going back to 2000. For the 28 days covering December, sometimes late Nov or early Jan depending on when the weekends were the following is the number of cm of oil used:
2000    22.5 2001    25.75 2002    26.0 2003    22.25 2004    19.75 2005    21.5 2006    21.5 2007    18.0 2008    25 2009    24.5 2010    23.5
December '10 was pretty cold (lots of ice days and lows -10C or so) but not windy. It is the wind that really cools this place out.
Each cm of oil is about 25l so we burnt 580l or so of oil in Dec '10 that's about 5800kwHr of energy.
