Mr. Chris Jones:

Yes. I may get the numbers wrong but, indicatively, if one is in an unmeasured household one is generally using approximately 140 litres per day. Someone in a metered household is generally using, say, 110 litres a day, so there is a significant difference. However, I would make the point that that is not comparing apples with apples. It is a self-selected group so the people who have meters have either moved into a new property, which tends to be more water efficient, with less supply pipe leakage etc., or, unlike in Mr. Millican's case, we have approximately 10,000 customers a year who opt to go on to a meter. That is because they are low users so to go back to the previous question about a single occupier, the way one gets recognition in our system is to go onto a meter and because one is a low user one will then have a lower bill. On average, customers pay less if they are metered but overall it is more costly to serve a metered customer than an unmetered customer.
