Mr. Paul McGowan:

Leakage is and has been a factor for water utilities throughout Europe. It has taken Great Britain up to 25 years to address leakage and even at that it has not reduced leakage to zero. Leakage levels still run at, I understand, around 20% in areas where best practice has been achieved.

On commercial charges, we have introduced the domestic charge on an assessed charge basis for mixed use customers. In terms of what happens to the relationship between that and non-domestic charges, that is a programme of work we will undertake. We will put together a timeline on that which will be published this year. It is far too early for us to say what the relationship between non-domestic and domestic charges will be, but suffice to say there are a whole range of issues of which we have to take account when we examine non-domestic charging.
