By choice we live in a band A Edwardian mid-terrace. There are the two of us here and we are careful with our water usage. The garden (veg) is not watered from the tap, although secondary use of bath water is often undertaken. We do not have a car to wash. Our luxuries are a bath every evening (we share the water) and the washing machine, usually used 3 to 4 times a week. We wash up once a day in the sink. I drink an awful lot of tea and I'm at home most days. We cook mainly from fresh ingredients so use water for potatoes, rice, pasta, couscous, quinoa, etc. The veg steamer sits atop of the carbs pan.
Monitoring our use, we calculated that a meter would result in our paying at least twice what we currently do. As we don't exactly waste water as it is, it is obvious to us that the original low tariff plan for meter charging to tempt folk over has long since been abandoned.
