Ours was £5.49 once all the big usage was done this morning (charge car, heating, showers, dishwasher and other things), then once it was just ongoing things (fridge, tv, Xmas tree lights) it went up 5p in an hour 🤷♀️. Put my heated airer on to see how expensive that is, will check in half an hour.
we are trying to keep it to £10 a day, but yesterday we went over because it was so cold.
