Morning @Tbeaumont1, and thanks for your answers here @BPLightlog and @johnr64.
@Tbeaumont1 sorry to hear what’s happened here. Please could you let us know whether you have smart meters? If you have traditional meters, then the ‘Usage’ pages of your online account and app will not show meaningful usage data.
If you do have smart meters, please check your reading history, and check that your smart meters have always been set to provide daily or, better still, half-hourly readings. If there’s been any gaps in the readings, eg estimated readings being shown for any period of time, then the usage comparisons for that time won’t be accurate. The ‘Usage’ graphs of your online account and app are only as good as the data that’s put into them, in that they only work when we are receiving regular smart reads.
And just to reiterate what @BPLightlog has helpfully advised - the ‘Usage’ pages have no bearing on your actual charged costs. To see what you’ve been charged, you’ll need to download your monthly statements. I’ll include some guides below that should help you with all this 👇
There’s also a possibility that your account has been retrospectively been re-billed. Our Support Team will be able to tell you whether this is the case, and why, and will be able to give you more of a breakdown.
let us know how you get on!
