Yeah, I've been wondering this. My monthly water bills are about 28 quid, it's a two bed house. I bet if we were metered it wouuld be less. But then I like the fact that I don't have to worry about water. My mum's on a metered water connection and, while she may spend less, it's also psychologically not great - she spends her whole time telling people to turn off taps properly and stuff
) and as I say it's just her and her 9 year old daughter. They have a yard, but nothing waterable.
