Hi Malc, Thank you so much for your information and advice. Mum will take the readings tomorrow, she has done a mini test this evening and it is rate 1 which has moved, rate 2 is static. We understand rate 1 is listed as night rate on the bills so this would appear to confirm the problem or at least a proportion of it. They will take a 12 hour reading as you suggest and take it from there. In answer to your questions their hot water boiler is also Gas, as is their cooker & fire. The estimated bill in March has I think been followed by 3 actual readings according to the EON gentleman in the call centre. Are you able to provide me with the numbers for the departments mentioned in your post please? Thanks again for your response, Jam

Thank you Topcat. I have checked the readings myself and they are correct, my worry is also that if the readings are the wrong way around they will continue to receive incorrect hefty bills...

Hi, I am requesting assistance on behalf of my pensioner parents' who have today received a bill for their Gas and Electricity of over £600 for usage since 2nd Oct. They have had no estimated readings since March and have had no new appliances, for this period of time they were actually away for 3 weeks, Their cooker and fire are Gas, however their Gas usage is fair. The problem arises with their Electricity, they are on an Economy 7 meter and have night storage heaters. I have called EON on their behalf this evening who inform me that since 2nd Oct they have used £500 worth of day units and £6 worth of night units. Considering that their only daytime usage is lights, microwave, television, shower, kettle etc. while their night usage incorporates all washing and night storage heating this seems to me to be disproportionate. The gentleman whom I spoke to at EON also agreed that it did not appear to make sense and he would investigate further. He has since contacted my father and told him that he needs to pay the bill and his payments will be doubled! My parents are in no financial position to pay this and more to the point the bill cannot be right. Their average usage over the last year was 5.7kwh & according to EON it is now 64.5, as I say nothing has changed. Their bill for the same quarter last year (1 extra month included and not having taken a holiday) was only £200. This is causing them so much upset and stress, can anyone please advise me. Thanks hopefully Jam
