Affordable Homes Programme

The Minister is doing a great job of expanding his speech. There is absolutely no cost to ensuring that there is an obligation for every new home built to have solar panels. Why does the Minister not look at that? My hon. Friend the Member for Greenwich and Woolwich (Matthew Pennycook), Labour’s Front-Bench spokesperson, has said that all these new houses have to be retrofitted. Surely the Minister can consider what can be done with new houses in terms of the environmental factors?
