Smart Meter - Increased electricity use this winter?

  • March 13, 2023

I just got an email from Ovo which has suddenly landed me with a massive increase on my electricity usage.

I have gone from averaging 14kWh per day from Dec 21 to Oct 22 to 44kwh since then. In early Jan it was 73kwh per day!

I have gas heating and water - there is literally no reason why I could suddenly be using 3 + times more electricity. 

Any suggestions? Am not sure why I have only just had my bill adjusted either as the meter readings have been sent automatically each month.

There’s some good advice in this thread, @JayJay:

 

  • Check that your online account has actual meter readings for the charges over both periods that you’re comparing
  • Check that the meter serial number listed on your account is the same as that shown on the meter
  • Consider changes in your household usage / weather during the times compared
  • Consider a creep test to see if your meter is clocking usage when nothing is drawing power (turn off all power at the fuse board and see if the meter continues to clock
  • Consider a meter accuracy test as a last resort. We have a guide on this here:

 

 

Before booking a meter accuracy test we’d recommend getting an electrician to visit your property to check that the appliances are working as they should. Electric appliances, especially heating and hot water tanks can use a lot of power sometimes. If you’ve got a smart meter then its highly unlikely the meter is clocking usage incorrectly - high usage, especially in winter, is far more likely to be a result of your household appliances.

@perniente Ask OVO to change your meter reading frequency to every 30min.

@BPLightlog  am testing with each circuit breaker off for 2 hours and checking readings. no meters nearby.

I'm having a similar issue. Submitted a meter reading which had a similar usage to last month and noticed yesterday all my usage stats for the past year have dramatically increased. For example my usage for gas in December was £110 but now they say is used £1108! Same now for the last two months.

I almost fell to the ground….luckily I've have screen grabs going back the last few months (we were transferred from SSE last spring), but I can't understand why everything has all of a sudden exploded…..

Hi Tim

 

Thanks for the reply.  Just spoke with customer service and the app is displaying kwh and not pounds!

Phew!

@BPLightlog @Tim_OVO i have taken readings all day and tried turning off various things. I turned the hot water tap back on and the use when through the roof  - it basically cost £1 to heat up which seems very high. there was a period this morning where the usage was also very high for several hours with nothing of note being used. i cant be sure but it feels like the meter is clocking fast. otherwise i cant explain why our usage has trebled. even the base level of usage is way higher than pre october. this is the graph showing our usage based on the readings (which are actual not estimates)

Interesting graph. Certainly an upward trend and no sign of leveling off. I don't think we have seen something like that on the forum before. Also surprisingly smooth. That is a big jump from the start to the end of the graph. Quite surprising there is no seasonal trend, not even a slight one. 

I would recommend you get your smart meter setup for 30min readings. It will be a lot easier to see what is happening then, for example spikes or a steady underlying usage every 30min night and day over several weeks. You would have a lot more points on your graph then

We have seen issues with those tap heaters from other users. 

Other things have been pumps for central heating, electric showers, immersion heating, air recirculation systems etc.

Looks like getting the meter checked out is certainly worth considering

@Jeffus thanks i will. Ovo suggested a creep test was needed before they would do a MAT test but I did that and the meter isnt running when everything is shut off. Its more likely something is drawing a lot of power or the meter is clocking fast. I did try switching various things off and checking the meter over 30mins intervals and i cant be sure but it seems anything significant (washing machine, hot tap) sends the meter running crazy. And none of these appliances are additional to our house since October. Hence why I feel like it’s the meter clocking fast.

That’s where the 30 min readings help @perniente as you can see where the high points are and check what was on at that time
