One odd thing that I have noticed with the udated app is that the usage shown by default is only for electricty.

So if you also have gas then you have to tap it and change it to show you the ‘Total’ for both fuels, you should only need to do that once and it will remember what you have set.

And then there is another twist to know about -

Remember that it is showing you usage for the Calendar Month, your actual billing period dates are almost certain to be different.

Tap “Bills” at the bottom of the screen which shows the bills. You can tap each one to see more details.

As an example my app currently shows my Total usage for this calendar month as £51.10.

However my billing period is 24th to 23rd of each month, (so ends today), and my actual usage for my billing period is £72.58, because it started a week before the 1st October.

Yes, I am aware of electricity and gas shows seperate and I check always total.

yes again I am aware of bills from 24th 24th and I do check daily as well and it was easy to calculate 5-6 days differences while daily shows £2 pound. I am taking a note of every single payment I do and collecting all invoice and I am sure something not right.And there is no contact number to ask them to check my account weird have been calling them but no luck not sure even I talk someone in Uk :)

Well it's my billing that runs 24th to 23rd, it would be quite a coincidence if yours did too.

Have you tried using the online account in a browser on a computer/laptop rather than using the app?

It has different options and personally I find it easier to keep track of things there.

Including downloading your billing which is much easier to read on a bigger screen.

From what you have said about paying different amounts then I am assuming that you don't pay by Direct Debit.

I will try. But at the end I have bigger screen excel where I write everything and calculate. The issue worst case scenario they can say their app do not calculate well and clean hands

I had a re-read of your post and believe I’ve spotted what is going on:

August App shows I owe £50 due to usage, I paid in £100.invoice shows £85.

September App show I owe £82 due to usage ,I paid in £120 .invoice shows 102 

it has been happening last 1 year like that , My usage of month much much less than invoices.

So for August you had £50 due to usage, but you then have to add a months worth of standing charges, and then apply VAT to that Total.

Depending on your tariff standing charges that could fairly easily take the £50 usage up to the £85 invoiced.

For August the difference between usage and invoiced was £35.

For September the difference was £20, but then when you acount for the £15 that you overpaid in August it becomes a £35 difference again.

It looks to me that the differences you are seeing between usage and invoice is simply the standing charges and VAT.

Hi @Alkan,

It seems that our forum volunteer has already answered this for you. Hope it was helpful.

Please let us know if you have any further issues.

Thabk you Nuke… Seem to me you sre right.I will check and of year report and will compare 2 full years to see :)) 

thanks again your time

Please see below.

Today balance -165

Usage for this month  -116 

and bill of this month 170 

I have been paying more than bill every month ao i do not have any previous debt as far as I know l.

Just one thing on the detail above … your usage shown on the chart is not for a full month but from 1st to the date the image was taken. I think Nukecad is on the right track with telling you to check for Vat but the usage charts only show calendar month information not billing months. They also mentioned earlier about usage charts only showing calendar month detail

Let’s see if I can explain it better.

The 2 screenshots are showing you different things, for different purposes.

Your first screenshot shows the usage (and only your usage) so far for the calendar month of October.
It does not include any standing charges or anything else.

Your second screenshot shows your (changing) balance day by day for your Billing Period.
It includes standing charges, VAT, and everything else.
It also shows your billing period date balances which are not the same as the calendar month usages.

The first one is only showing your usage since the 1st of October.
The second one is showing your balance since 24th September.

So to start with there is a weeks difference between what is shown on the different screens, then one is not including any Standing Charges, etc. whereas the other does include them.

Again, they are showing you different things, for different purposes.

You use the first one for keeping track of usage in a calendar month, it is not useful at all for your billing and is used for other things such as Power Move.

You use the second one for keeping track of your billing, and how much you owe on any particular day.

If/when you don't realise that difference and try and mix the 2 different displays up then you can get confused.

Today balance -165

Usage for this month  -116

24th to 24th and todaybis 29th so today balance is only for 5 days different. Also previous month I made balance 0 on 1st of month . 

and bill of this month 170 

why bills 170 while today balance nealy same which is more than bills days ? Nearly similer ? What is VAt ? £8 ??? ;)) 116-165-170 , differences and VAT £8 ;)

We posted at the same time, please read what I posted above which explains it better.

You are confusing usage with balance, they are different things.
You are also confusing what date things are shown from on the different screens.

In all your notes on different charges, you are also not taking standing charges into account @Alkan. These will depend on your plan but would be something like 56p for electricity and 30p for gas each day so a full month of standing charges add approx £26 each month.

Vat is also not a flat amount but a percentage of your monthly charges
