Environment Bill

My Lords, I thank the Minister for assuring us that he is talking to the Ministry of Housing, Communities and Local Government about greywater and other related issues. I ask him to work really hard on this, because the longer it goes on, the more homes—hundreds of thousands—will be built that are not up to the standards that probably everybody in this House wants, including the Minister. Can he give us some idea of when we will get the new standards up and running, be it on greywater, flooding, heat conservation, net zero, or keeping houses cool in the future when temperatures rise? This is urgent, and housebuilders need to get on with it.
