I know I should have been expecting it, but this is going to be crippling! Our fixed term ran out in January, was advised to stay on flexi tariff (our bill to fix would have doubled to fix in any case, which I cant afford). We have a smart meter. Our daily usage in winter with heating was maximum £5 a day, even on really cold days with heating on for a good portion of the day. That is with 3 teens using electronics at some point too. Yesterday, no heating on at all and it was £5.50 when i went to bed. I have been around the house and turned everything off I can. Got up at 6am and was on 97p usage already (used to be approx 50p). No heating on. TV hasnt been on. No electronics on. Used oven for 30 mins this am. Currently at £2.50 already. I want to cry :(
