My partner who dealt with these things, passed away at the end of June. I let the DD's from her account continue until 29th Sept, by which time I was advised by E.On that there was a shortfall of around £105, based upon actual readings I took on that same date - when I had the account transferred over to me and a DD with me. Its a dual fuel account E & G.
Due to her health issues, her consumption of both was quite a bit more than it has been since she passed away, but I agreed with them a DD of £80 pm, to let it pay the shortfall off.
She wasn't bothering to give them readings and they were not calling to make their own, hence the shortfall.
Now I am feeding readings in for each, on a weekly basis, so I can better see what is going on, but....
The online Energy Overview thingummy, seems to come out with completely daft figures and a daft figure for what my DD ought to be.
In July, August and September of around £52 per month for the combined E & G supplied. I'm paying £80, so that should quickly pay off my partners earlier shortfall - yet the web page is suggesting I will use £1,130.44 for the year, so need to up my DD to £130 pm.
Might the site's calculation be based upon several previous years of consumption, rather than what the consumption is now?
