@Windy our average is around 8KWh / day, unless we’re charging the EV (then it’s 70+!!)
Three bed link detached, electric oven (that’s not getting much use atm!), my wife is home nearly all day, and a teenage son who loves his (well, it was mine…) gaming PC with a 40″ monitor who stays up until 2am every day…
We’ve also got gas heating and hob, and a combi boiler. Do you have storage heaters? Or an immersion heater / hot water tank?
