Professor Tom Collins:

There are two pertinent questions. It has to be retrospective, ascertaining the median use last year. We now know what the median is. My sense is that one might then add on a decile or two in percentage terms. Obviously, there will be some variations. Then there will be specific cases, such as those associated with medical need, and they will have to be addressed. In the submission, I mentioned that the forum would happily get involved in that kind of process. There would need to be an appeals procedure. I have not figured out how one moves from individual consumption to household consumption. I suspect there would need to be some form of self-declaration such that one could say that, as an individual, one was allocated a certain number of litres per day. Of course, we are charged per household so one would have to identify one's household and the number of individuals therein. That is an administrative complexity and I am not sure how we could fully get over it.
