Can someone help me understand my gas usage

Good morning. 
I am on a bill monthly account but always make sure I am in credit so log in daily to keep an eye. 
 

Im very careful with usage of gas/electric 

I only put my heating on when needed usually twice for an hour or 2 when freezing in the evenings and only to keep dampness away as i tuck myself up with electric blanket

If I have my grandbabies I keep it running and last week I had them for 1 days and 1 night so kept on heating all day as both under 2years 

Ive been worried about the cost of usage but I must be in the twilight zone as price doesnt make sense. The Wednesday my heating was on all day and tuesday was a ‘regular’ day but look at the difference in cost? 
 

Does this seem right?

Im in a 3 bed semi bungalow with windows that desperately need replacing so very very draughty

Thank you in advance

I agree that that looks odd. However, you can’t ever rely on the usage charts to tell you what your energy costs. The figure shown for the daily cost be an estimate of what the gas has cost. This will depend on the calorific value (CV) of the gas on that day, and the CV may not have been available when the chart was viewed. 

You’d get a better idea of what a day’s use is costing by multiplying the kWh figure (itself an estimate) by your unit price and adding the standing charge. Both of those should be given on the Plan page. Don’t forget to add 5% for VAT once you’ve done the sums. Your gas on Wednesday would have cost something like
[(63 kWh  x £0.062/kWh) + £0.305/day] = £4.21 + 5% = £4.42. 

If the chart is still saying £1.41 for Wednesday in a day or two’s time, I can’t imagine what’s wrong. Let’s hope someone else has seen this sort of thing before.

Morning ​@Katiejohnson and a warm welcome to the OVO Forum! I hope you’re well.

 

To put your mind at rest, what you’re seeing on the app is just an estimate of where your usage is falling based upon the info you would have provided about your appliances. There’s no way it can actually know what appliances are using, and when. It’s all just estimates, and the info will never be accurate. 

 

You could try amending your home profile to say you don’t have gas central heating, but just to confirm, it still won’t give you accurate data as to how much each appliance is using To do this, select the person icon on the home page of the app (I’ve circled it in red on the screenshot below):

Then, on the next page, click ‘Home profile’ and you’ll be able to add in some information about household and appliances:

My advice is to check that your smart meters are providing half-hourly readings. If they’re not, set them via the app to do this, and you’ll then get a nice detailed breakdown of your usage on the ‘Usage’ pages. You can then look at the fluctuations of your usage at different times of the day, when different appliances are being used. You can then use this to get an idea of how much different things may be using. I’ve included some articles below that show how to set your reading schedules to half-hourly, and how to use the ‘Usage’ section of your account:

 

 

I hope this helps 😁.
