Thank you Malc. I think my issue has been resolved now. Apparently, my day & night rate are charged at the same price so the figures being the wrong way round won't affect my bill. At least this is what I have been told by the very helpful lady I spoke to the second time I rang. The guy I spoke to initially, seemed to just try to fob me off with incorrect information. I will be sure to update this thread if I need to. Thanks again Malc.

Hi, I really hope someone can help me with this. I attempted to input my Eon readings last night and to my horror, I noticed that all previous readings have been in-putted the wrong around. The Normal rate appears in the Night rate box & visa versa. Eon have sent their meter readers round several times over the course of the last 5 years and not once has this error been noticed or rectified. I rang Eon to report this (about an hour ago) and was told that I have to ring them back later this afternoon as they are currently experiencing a data issue on their servers and they can't access the information they need to in order to deal with my issue. The man I spoke to did say that the readings have been wrong since 2007 which was when the meter was installed and the bills will be amended and back-dated to 2007. Obviously, I'm worried that I've been underpaying for the last 5 years and will now face a huge bill that I cannot afford. I have read up on the billing code and I think I should be covered under this, which means they'll likely ask for back payments for the last 12 months but my argument is as follows: If I have been underpaying, and it's because they have incorrectly set the meter up/failed to notice any errors until I reported them, why should I have to pay them anything? Eon's method of inputting meter readings in online is hugely flawed. Once the readings are in-putted incorrectly, there's absolutely no way of rectifying it. It automatically sets this as the preferred order which means all subsequent readings in-putted thereafter are incorrect. I would really appreciate some advice on how to take this forward. I am dreading ringing them back in a couple of hours time. I have enough on my hands at the moment without entering into a lengthy battle with Eon. Thank you for reading this and thank you in advance to anyone who responds.
