We use 10KW a day in summer (23 degree average temp, so aircon not needed), but it jumps to 20KW a day in winter 5C average temperature.
We have a wood burning boiler stove, as it was over 80KW a day before that.
3 storey building, 1100 sqft total. 4 people, 2.5KW solar, 4KW solar thermal, 8KW wood burner for space and water heating. Heavily insulated walls and roof.
Our off peak use (7p a KW) has gone up since last week, as we average another 10KW a night charging my Nissan Leaf EV.
