I've experimented by turning the central heating off overnight and it
doesn't seem to reduce gas consumption much. It seems to mean that the
house is horribly cold for the first hour of the day and the heating
never switches off all morning and most of the afternoon. I think the
thermal momentum of a brick building and its contents must mean that
cooling down and warming up take an inconvenient amount of time.

You don't have my gas bill!

I like my house, but it's expensive to heat, and having the CH off
overnight makes a big difference. Having it come on again at 6.00am
means its warm enough by the time I get up.

I need to do other things to reduce my energy consumption like replace
the Aga with something from the 21st century and bring my EPC rating
up from it's currently dire E rating. But for now I'm trying to live
comfortably while working through the various improvements.
