Energy committee chairman Tim Yeo lambasted the power bosses for failing to show "any expression of real concern for your customers".
I have to say after 45 minutes the tone of this discussion and its contents has been utter complacency from all of you.
The trade body can't provide the most basic information on a totally predictable question.
You have lacked any expression of real concern for your customers. It's absolutely typical of a monopoly, particularly monopolies whose charges are not very visible to the customers who have to pay them.
Mr Yeo warned the witnesses to "step your act up" if they wanted to "impress" the committee.
