We have made enormous strides on this through the green deal. We have recognised that in the United Kingdom our gas prices are the lowest in the EU15 and our electricity prices are about the third lowest in the EU15, but the total bill is much higher because our homes and businesses are very energy inefficient. The green deal was the first comprehensive measure introduced by Government to address this and to be rolled out across the housing stock. I know that the hon. Gentleman welcomes the ambition that we are setting out, and we are determined to make this fundamental change.
