I have just received an electric bill that suggests my daily usage kWh
(over 100 days) is 37 kWh a day ?
(British Gas)

We have gas central heating - no electric heaters.

Two bedroom detached house - two adults one baby.

Washing machine/dish-washer on probably an hour each five times a
week.

No other excessive high power stuff in the house....(computer 200W on
all day = 4.8 kWh day)

Dodgy meter ? Or next door are wired in...

That seems high, I happened to be working out our average today, about 13
units per day in the winter, down to about 11 in the summer (it's hard to
tell from the bills as we were away for 3-4 weeks across July & August), so
your useage is about 3x ours.

As Andrew Gabriel has suggested, try switching things off one by one - or
buy one of those power monitoring meters for about £10 -15 to see where the
power is being used.

Is it possible you've knocked an immersion heater switch on?

Also check your lights, Mains voltage halogens can add up if you have a lot
of them, and low voltage halogens can be expensive if the transformer is
'always on' - we've got some LV bedside ones that are great, but they run
off plug-in transformers that are always warm; we've put them on a timer so
they only take power between 10pm and 10am -along with the upstairs DECT
phone charger cradle
