Anyone had a water meter fitted? Water bill go up or down?

[clumsymum]

I've just opened our water bill for this year, and like everything else it's gone up.

I've always been afraid that if we had a water meter our bill would be higher, what with bathing DS, dishwasher on every night, washing machine 9 or 10 times some weeks.

Any experience?

Ours is £20 per month. Family 4 we have a bath everyday, washing about 10 loads a week, dishwasher once a day.
