Its going to depend on your insulation etc for your particular property, but thats what I discovered

We had a perfectly timed incident of our heating timer/switch or whatever breaking the week before Christmas and the engineer being like "I can't get parts until the 5th of January"... We could still turn the heating on and off at the mains switch on the wall... But (being lazy) inevitably we were just leaving it on all day from about 7am - 11pm.

Usage for the month was less than 10% more than the previous month when it was only on half that time, AND it was during that insane -7/-8 cold spell.

I dunno.

To be fair we hopped on the air fryer trend and I love the stupid little thing so pretty much never use the gas oven any more which will help.
