My property is using over 30kwh per day with no heating on (Air Source Heat Pump) when no one is home - how can I check what's using the energy?

That sounds pretty frightening, so the first question is do you have a smart meter? Is it sending half-hourly usage data as well as meter readings? If you look at the reading history page, do you see actual or estimated figures? On your Plan page, is the Future Annual Consumption figure anything like your actual consumption for the past twelve months?

Unusually high numbers like this normally arise from unrealistic estimates made by the system, or from power-hungry equipment left on by accident. If you can see half-hourly usage data, they will often give clues to what’s going on.

If you have half hour readings on your account from a smart meter, this can give you a guide on what is using power by looking at how much is being used and when during a day ​@HK17 

Aside from the ASHP (although that might still provide heating for hot water), there could be any number of appliances or circuits drawing power but if you are looking at an accurate power draw of 30kwh per day, there will be something significant causing that.

Note that if you don’t have regular readings sent either via a smart meter or manually, your usage would be estimated - if you haven’t already done so, check the readings on you meters to see that they agree with your account.

Thank you for your replies

We have a smart meter. Readings seem to be just daily? 
Actual readings not estimates.

Future annual

Future estimate is on this level? 
 

I don’t know how else to check or maybe contact OVO as moved to them in Oct 24 but was high before moving. 

If this was me I would watch the meter. It probably has a red flashing light that flashes faster as you use more power. Then if it was unclear what was going on I would switch stuff off until the power use dropped. This approach works if you have a continuous power drain.

If its a short time high power drain I would expect something to be getting hot since using a lot of power in a short space of time must produce substantial amount of heat.

Good luck

Hi ​@HK17 ,

Could I take a step back and ask just where you are looking and seeiing this figure of over 30 kWh?

On the meter itself?
On the IHD?
On your online Account in a browser?
On the OVO app?
Somewhere else?

Hi ​@HK17 and welcome to the OVO Forum.

I’m sorry to hear what’s happening here and we’ll do our best to get to the bottom of it. If you could kindly answer ​@Nukecad’s last question this’ll give us more of an idea of what’s going on. Feel free to include any photos or screenshots that will be helpful, just remember not to include any sensitive information, eg your OVO account number.

It is on my past months figures on OVO unless I’m reading it wrong? 
 

Those look suspiciously like estimated figures. Smart usage data amounts will normally be formatted as links (e.g. in green and underlined) with the link redirecting to the half-hourly data page for the day concerned. 

From the menu on the page you’re showing, select Meter readings > View reading history. On the Electricity reading history page, deselect Hide estimates. You should now be able to see whether the smart meter is indeed sending in daily readings. 

Your latest bill will tell you whether it’s based on estimated or ‘smart meter’ readings. 

Thank you
