I've just completed the Home Energy Masterplan survey on my house. I've not completed the analysis of all the options, but the calculations show that the house has an annual CO2 footprint  of 8.8 tonnes of CO2, and energy bills will be about £1420 per year. This seem a bit much, so I'm keen to get some stuff done before winter.

I'm planning to monitor progress on imeasure.org.uk - this is run by Oxford University and allows you to chart your energy use online, compare with other people, that sort of thing. I'll also be using it to compare against the predictions from I've added a couple of readings so far, will try to add readings every week, not sure I'll manage but will give it a go.
