A bit OT, but our electricity usage has always seemed incredibly high to
me. Not how much we pay, but the actual units used. Looking back, the
last time I read the meter was 26.09.13, which is almost exactly a year
ago. Reading it today, I find we have used 9128 units over a year.
No electric heating. No tumble dryer. Just the usual washing machine,
dishwasher, two fridges/freezers, two desktops, two laptops, kettle,
lighting etc. An I naive, or is that a lot of units?
Hmm.. is that a ranch!
4835 here last year; largish farmhouse with outbuildings on same meter.
No electric heating, gas hob, gas hot water.
Tumble drier, dishwasher in regular use.
Check the decimal point! How do you heat water?
Seems a lot to me. Our usage Sept 13 to Sept 14 is 4253 units. Two
people, d/w, 2 FF, two small desktops and screens, telly. Oil central
heating will consume a bit, with pumps and that, but I dunno how much.

In much the same manner as fish follow migrating caribou."
It does seem on the high side. But I guess it really depends on how
often those large appliances are run and whether you have lighting you
could roast a turkey under.
I use about twice that but am on full electric heating until we get
Time to do a meter calibration check I think...
Turn *everything* off.
Then apply one well known load - perhaps a heater or a fixed number of
lamps. Aim for 2-4 kW.
Count the disc rotations or LED flashes over a fixed number of minutes
and check against your known load. The units of energy per rotation/LED
flash will be written on the meter.
If you find any serious discrepancy, ring the DNO and ask for a them to
do a calibration check, which they *must* do on suspicion of a faulty meter.
If it is found to be inaccurate, you will be able to lodge a back claim
for overcharging - though I am not sure how anyone decides how far back
you can go.
Well an average household uses around 4,400 so your figure is high by
that yardstick *but* as ever so much depends on circumsatnces - how many
people in the household and lifestyle (and hence how often w/m and d/w
are run); how PCs etc are used; whether lighting is low energy; and so
on. Eg our electricity usage is dominated by 2 PCs (plus modem, router
et al) on for 12+ hours a day on average, and hence flat throughout the
year. (The increase in lighting, supplementary heating etc in the
winter is balanced by the decrease in usage by (old) fridge and
There are ready reckoners you could look at with your actual usage of
w/m, d/w etc etc to get a better handle. But let's start with the
a. how many people in the house?
b. do your *bills* show you using around 9,000 kWh a year?
An awful lot. We have almost the same as you - no dishwasher but a
tumble dryer. Our heating is Economy 7 - so metered separately.
Excluding the Economy 7, we have used just short of 3000 units over the
last year. We try to be economical with our usage, but not that severe!
I would get the meter checked if I were you.

Thanks for all the comments. Seems to me you're all using something in
the range 3-5000 units. Why are we using over 9000?
Yes, large house. 6 beds. However, 3 people (2 adults, one child), and
we don't run lights or anything else in the rooms not being used. Oil
heating, no gas, so leccy covers all the usual stuff. Yes, we have two
desktops and two laptops on 24/7. Router and homeplugs. Fluorescent
lights in the kitchen are left on 24/7 (for the dog ...). Most of our
light bulbs are either fluorescent or low energy. Showers just use
domestic hot water from the tank. Immersion heater very rarely used - 2
or 3 times, when we've run out of oil. One freezer, one fridge/freezer
and a fridge. Dishwasher used every night. Telly perhaps a dozen
nights a year. Washing machine twice, sometimes three times a week. No
built in tumble dryer. Wifey uses hair dryer and straighteners once a
week. The usual mobile chargers, radio etc. Electric kettle - we drink
a lot of tea. Electric hob and oven. We use a combination
microwave/oven a lot, to avoid heating the big oven. Can never remember
the types of hob. Glass top, the rings glow red when on. Always
switched off at the wall when not in use.
We had a new meter installed May 2004. Readings (actual) from old meter
Usage therefore 17468 over 19 months, or roughly 11032 p.a. ten+ years
Readings from new meter (actual not estimated) :
Usage therefore 73161 from 23.06.06 to today. 8 years 3 months. 99
months. 73161/99 x 12 = 8868 average p.a.
Seems unlikely both meters would be wrong?
9128 / 365 = 25kWh/day, which is just over 1000W permanent load.
Mine tends to be 600W, dropping to 400W when everyone in bed.
What are your 'always on' items? (Most other things can be ignored.)
Do you have a 300W/500W outdoor floodlamp which is on dusk-dawn?
Does the figure vary much between summer/winter?
I would suggest buying a power monitor of some type, either for checking
the usage of individual appliances, or the type which clips around the
meter tails and reports on the whole house.

Funny you should say that. We have a shop on the side of the house,
with separate electricity supply. I began to suspect that their leccy
was fed through our meter first! However, I turned mine off this
morning, and the shop lights stayed on.
