Action on Climate Change and Decarbonisation

I certainly agree that incentives and greater financial support will be crucial. However, does the hon. Gentleman agree that another way of tackling the issue that the hon. Member for North East Bedfordshire (Richard Fuller) raised would be to make very sure that there was a requirement to up the energy performance certificate rating before the house next changed hands or was put on the rental market? In other words, if people wanted to sell their house, they would have to make sure that it was properly insulated. In a sense, we would have both the carrot and the stick.
