Climate Change and SustainableEnergy Bill

My hon. Friend is absolutely right. Part of the process of reducing demand is to ensure that new houses are built with minimum quality criteria for insulation. One of my concerns about the Deputy Prime Minister’s initiative for more low-cost housing—I believe that it was a good initiative—is to ensure that builders do not cut corners by building houses without the necessary insulation. Through the sensible insulation of housing, we will have warm homes, reduce costs for the poorest in society and consume less energy.
