It's now a week since I made those changes to the programmable thermostat, and here are the results so far.
At 1:30pm today, almost exactly a week later, the gas reading was 7062.6 cu mtrs. Last week was 7041.0, so I've used 21.6 this week, compared to 30 the previous week.
If that translates to the whole year, then I've just knocked my annual heating impact down from 1.5 tonnes of CO2 to around 1.1 tonnes. Given two of us in the house, then it means that my gas alone accounts for 55% of my target of 1 tonne per year. That's a big improvement, it was 75%.
I'd still like to get it down to something a lot less, but it's a great start!

You saved over £130? turn it off most of the time and you get a gas bill of less than £150 per year. You will get an over spend on herbal teabags and have to wear a few more clothes but oh well you'll still be doing a lot better.
