The hon. Gentleman makes an excellent point. We often debate the cost of living in this Chamber. One of the big contributors to the cost of living is the cost of gas and electricity. This Parliament legislated for a cap on energy prices—I welcome that and our Select Committee conducted important pre-legislative scrutiny work—but the cheapest sort of energy is that which we do not use at all. If we improved the energy efficiency of our homes, we would have lower bills. A Government investment strategy through the National Infrastructure Commission that retrofitted homes, particularly for people on lower incomes, would therefore help to reduce our carbon footprint and put money back in the pockets of some of our poorest constituents. That would be a double win and we should all work together to achieve that.
