I moved into a two bedroom house with my youngest daughter a year and a half ago, only us in the house except when my eldest dd (21) comes to visit occasionally. Our first water bill was about £250 for six months which was relatively high for two people I guess but we have a dishwasher so not unusually so. However the last two bills have been double that so £1000 for the year, which seems absolutely insane. It's more than I was paying for water when we lived in a four bedroom 3 bathroom house with my eldest daughter (who was a teenager at the time so spend half her life in the bath or shower!) and my ex husband.
I've queried it numerous times with the water company and they have supposedly checked the water meter and said it's correct, as it wasn't moving when nothing was on in the house. After the last huge bill they said the consumption had gone down and was now in line with what it should be but then I get another bill just as big at the last. Nothing has changed, no extra appliances, building work been done and it's just a tiny two bedroom terrace with 1 bathroom and no garden to speak of so not using extra to water plants or anything. No dripping taps or obvious leaks. We even share bath water most mornings. Dishwasher goes on once a day at the moment as we are both home all the time but up until lockdown it was once every three days roughly. About 4/5 loads of washing a week max.
It just seems absolutely massive. When I search average water bill it seems to be over double the typical 5 bedroom house cost! What is your water bill and for how many people? We are in the south east if that makes any difference. And does anyone have any advice on what could be causing it?
