As I said in my statement, the years and years of under-investment—the complete opposite of what was promised when the energy system was privatised in 1989—have led us to this place. That has been a very large contributor to the challenge with energy Bills that we face now. The Committee heard evidence from E3G that as much as £500 in profit is made in the private sector from an average household bill. When we recommended that the debt be written off by using the excess profits made by the network companies, we were told that that would cause a chilling effect on future investment. Of course, that problem would not exist if we had not gone down the privatisation route in the way that we have. My hon. Friend makes a good point, but we are where we are, and we are going to have to find answers to the question of how we bring down bills further, in addition to the measures already taken by the Government.
