The smart meter shows electricity consumption that was not there. Why?

To install the smart meter, I had normal power consumption. After installing this, the counter suddenly increased. I wasn't able to determine how much electricity consumption had increased. But from April 15 to September 25, 2023, I was not in the apartment. I turned off everything. even the electricity consumption indicator which supposedly consumes 1kWh of electricity per year. I also turned off all the sockets. I also unplugged the refrigerator and washing machine. Unfortunately, after receiving the bills, I saw in black and white that I used over 111 kWh per month when I was not at home. Nobody has a key to my apartment. How is it possible?

Hey @Dorota Parker,

 

From the screenshots you’ve sent it does seem that your meter is communicating fine, and that usage was consumed. 

 

I think the best advice for you would be to follow these instructions:

 

What’s the best way to locate an energy guzzling appliance?

 

Worried that your electricity usage seems high? By checking the usage of each circuit you might be able to find out the particular appliance which is the culprit. The meter will need to have decimals showing in the reading for this test to be useful:

  1. Leave the main breaker in.
  2. Turn off all individual circuits (on the fuse board, for example).
  3. The electricity meter should stop clocking usage. If not, there could be a short in the fuse/breaker panel box or an appliance connected without fuse/breaker protection. An electrician will be needed to investigate this.
  4. Turn on one individual circuit.
  5. Watch to see if the electric meter starts to clock usage.
  6. Turn off that individual circuit and turn on another one. Again, watch to see if the electric meter is clocking.
  7. Repeat step 6 until all individual circuits have been checked.

You’re looking for a circuit that causes the meter to clock a lot of usage, compared to the other circuits. There could be a problem with an appliance or a connection on that circuit. We’d recommend contacting an electrician to check the appliances on this circuit, particularly if there are any old or potentially faulty appliances plugged in.  Find out the average usage for each appliances on this great guide and some great energy saving advice on the Centre for Sustainable Energy.


How do I perform a Creep Test on my electricity meter?


If you’ve been unable to get to the bottom of an increase in our usage by locating a greedy appliance, the next step would be to carry out an initial check on the accuracy of the meter with a ‘Creep Test’. To carry this out: turn off the power to your fuse box and check if the meter continues to clock. If the meter clocks (more than 1 - 2 units which could be down to residual power in the wires)  then it's either faulty, or clocking someone else’s usage.

 

If your meter is in a communal meter cupboard, sometimes the meter details can get mixed up. Firstly it’s worth checking the meter serial number on the meter matches the serial number registered on your account. You can see this on the ‘Meter readings’ page of your online account.

Hi everyone, 

 

A ‘technical site survey’ engineer visit can be booked: 

 

 

The meter itself and the wires from the fuse box into the meter can be assessed as part of that site survey. Anything else is either for the Distribution Network Operator (for the main fuse or the cables into the house) or an electrician (for the cables from the meter, as outlined here:

my child unplug all how it was before we go out. Only left programmer and fridge and was smaller usage as we left and fridge was unplug too. 

The same time I do not understand - I have today usage 10.02kWh and It not show usage after 4pm? When I saw the OVO price for changing meter they can charge my child any money to cheat her too. She is not working and has more 20000 student loan  and if OVO come they will charge any money they wanted and they can cheat her too. If we will found anybody better way is to sell this flat. Now I know that boiler how we left for 4,5  months does not done this usage. The metalic box when was removed I think will stop usage 0.07 kWh too, but this usage was 30 min before we came home at 9pm. was not possible somebody took on Saturday 9pm this box. There is another problem and the problem is not with our applicances because all was unplug.

Morning Dorota. Thanks for that.

I’m no expert but as far as I can see that shows your smart meter is working perfectly, you don’t need to have it replaced. The data is uploaded to OVO in chunks - I’m on Octopus and I don’t have any data at all for yesterday ! So already having data to 4pm is very good. The rest will be uploaded soon.

That 0.07kWh per half hour has gone, the data for the 10th looks exactly as it ought if as you say only the programmer and fridge were on. I think your problem has gone away. 
True, there was something drawing electricity on previous months but other than the box of wires we can’t now explain it.
