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
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.
Hello @perniente Was your issue resolved? I installed the new meter and the bills are skyrocketing. I was paying like £60-70 per month using the previous meter. I paid the balance fully, and it was zero just two days ago. Now, it has increased to £11.7 in just a just two days. My energy usage has not changed and I am not sure what the issue is.
Sorry to hear of your higher charges since having new meters installed. I’m assuming they’re smart meters if they were recently put in - it is unlikely that they are clocking incorrectly due to how highly meters are calibrated these days.
Firstly, I’d recommend making sure that the new meters have actually been updated on your account (this can take up to six weeks from the installation date. If the meters haven’t been updated then we may be billing to estimates. I’m linking in another Forum page that gives handy info for checking if your meters are set up on your account:
If the meters haven’t been updated on your account, you may have to wait up to six weeks for this to happen. If you contact our Support Team they will be able to fully assess the issue for you, and maybe even get the meter details updated on your account if they’re not already there.
If the new meters are on your account, you’ll need to check that they are in comms and sending us reads. You can check your reads online, or on the app, and cross reference them against the reads on the meters themselves. Log in, click ‘Meter Readings’ and then ‘view reading history’. The above article contains instructions for taking manual reads from the meters.
Finally, if all reads are in line and there are no issues with billing or estimates, then the issue may lie within the property itself. It would be worth checking if there are any changes made within the home, or any appliances left running. I had an issue at my own property one time with a couple of huge bills - it turned out that I had accidentally switched my immersion heater on at the wall so that it was running all day 😑.
The above checks should help you ascertain what the issue is, but I would recommend getting in touch with our Support Team for a thorough investigation. Make sure to ask them to set your reading schedule to half-hourly. I really hope this is solved fo you soon!
