Becuase of COVID I needed to lock down with my family in order to provide care due to a disability. Well surprise surprise my gas usage for the last three years has been much lower than their estimates. So low in fact they refuse to accept them. The fact I have heating only and we have also had very mild winters and hot summers they also regard as a flimsy excuse. The gas stove is also an induction and I have an on demand system electric shower. Apparently they don't get why I am not using gas for anything. So I dutifully submitted date and time stamped photos. Which after 6 months of arguing were finally accepted. Only to see two weeks later that becuase there has been no rise in my meter for the last few months they have removed it and replaced with a huge estimate. That I have some how used £2k in heat during the month of June! 😳 Now having a south facing house with lots of windows that turn this into a greenhouse I could see spending this on air con. If I had that. But heat in June? During the hottest year on record? Hell no. I am constantly sweating. Talking to their customer service agent he informed that to get accurate bills the meter readings must be different each time. Submitted 7 days apart. And mine are all the same. I told him that's impossible. It's only heat. Not water. Not electrics. Not cooking. Just heat and not even all the rooms need it except on the coldest days. He told me nothing can be done and I will have to pay £1k a month or turn the heating on full so they can see how much I use and readjust their estimate. I am one person in a tiny 2 bed house. How can I possibly use £1k of gas a month. With a boiler that is turned off. The difference us huge. This is not a Smart meter it's an old meter. There is no meter reading error. My bill before COVID was £65. Then after this I raised a complaint and got hostile emails threatening my with bailiffs if I don't continue paying. He said it was my fault for not using using enough heat and not being able to demonstrate 'weekly use in May to June'. He was rude, condescending and utterly clueless. I suggested then leaving and he said they will block me! I said what if I sell the house? He then said they will find me and sue me. I said for what? You have taken £15k out if my bank account for gas I have not used? He said we can add more charges to your final bill. I said but I haven't seen the last two quarterly bills. Still waiting. Becuase 6 months ago the meter reading was accepted and it was going to be recalculated. With a refund sent. Nothing happened until now. And now it's worse. Back to square one again. The boiler is off for summer. No heat needed. I live in the south and it's hot!
