I have been playing about with the degree days figures for the south east (I can stick the spreadsheet up somewhere if anyone wants)
Got the raw data from:
So based on those, it looks like (for the south east of England at least) there really was a 20% increase in the number of degree days over the past 12 months. (this past year being colder than average, and the previous one being warmer).
So the question is, how have you seen this reflected in your heating bills?
East Midlands rather than South East, gas C/H no changes to system in the last year, average kWh gas/day increased 34% during the past 12 months.
Compared with last year/Winter: Oct. '12 - Mar. '13 inc. about 1MWh more; for Apr. '13 - Sep. '13 inc. about 475kWh more (so far!) - about the same as last 'Summer'. The first figure, however, is about the same as for '10 - '11. The Summer of 2011 used none apart from a couple of kWh for testing.
When I first saw the title of this thread I wondered why you were paying to heat your relatives!
However, I'm quite pleased with my leccy bills this winter gone down quite a bit, but maybe its just been less bitter then....

12 months to 1st July 2013: 18842 kWh 12 months to 1st July 2012: 16680 kWh
In March this year we used 3010 kWh (the month of the Siberian wind), against ~2550 kWh for each of the preceding 3 months; and 1887 and 1993 for March 2012 and 2011 respectively).
March 2011 48kWh/day March 2012 57kWh/day March 2013 83kWh/day
Much the same increase for Mar 2013 over the others. It was a bl**dy cold wind and it blew for what seemed forever (3+ weeks?) :-(
2011 Jan 2258 kWh, Feb 1617 kWh, Mar 1415 kWh 2012 Jan 1943 kWh, Feb 1943 kWh, Mar 1269 kWh 2013 Jan 2381 kWh, Feb 2123 kWh, Mar 2505 kWh
Looking at the data, March 2013 was my highest monthly figure since Dec 2010, which at 2842 kWh was the all time high in 22 years, most of which were with an old "inefficient" boiler and less loft insulation.

Two months with *exactly* the same consumption?
Our use is in "cm of oil" so possibly not much use, a cm is about 25 l or about 250 kWhr:
Mar 2012 9.25 cm approx 2300 kWhrs Mar 2013 20.75 cm approx 5200 kWhrs
That doesn't look right!
Looks at weather records:
Mat 2012:
Hum maybe it is, 2012 guesstimated mean of 5 C ish until about the
24th when it gets decidedly warm, not much wind. 2013 guesstimated mean of 0 C with a week of ice days towards the end, and moderately windy when cold as well. You can see the internal temperature not being maintained...
Looking at the degree day data, the year including Dec 10 was very nearly as cold as the year we just had - so that makes a certain amount of sense.
I thought that as I typed it out, so I double checked, and the figures are indeed correct.
