I'm in the UK and I'm on a water meter, but, when I moved house, downsizing, I thought my water bills would go down as my garden doesn't need anywhere as much water, I have no bath, just a shower and there's only me, but, my water bill has increased from £24 a month to £39!! I called Welsh Water and they say it's correct, although I have no idea how. So now I'm being ultra frugal, watering my plants with used dishwater, not flushing the loo after every use and making sure my laundry loads are more economical, so if the bills don't go down then I'm going to insist on them checking my meter instead of letting them fob me off. So get someone to check that there are no leaks or that your meter isn't faulty.
