My Lords, far be it for me to improve or elaborate on anything that my noble friend has said. I just want to pick up a couple of points in the context of the code for sustainable homes.
That code has been in place since 2007. People are quite clear about the benefits. It has led to improved standards and to efficiencies. That is acknowledged by bodies such as the Environmental Audit Committee and the Local Government Association and many good public authorities. It is familiar, it is quite elaborate—that is true—but on the other hand, people know how to respond to that and how it benefits them. It has led to great energy efficiencies. Will the Minister tell me what the problem is that will be solved by removing the code?
The noble Lord, Lord Rooker, has quoted extensively from the BRE. It has probably provided us with similar briefings. The briefing points out that the new arrangements will mean that, in the future, energy performance set through the building regulations will be lower than many local authorities currently require, with the need for a special application to use optional regulations. This takes us back to the previous debate, and the shift in process and relationships, and in how things are decided, who gets to decide them and on what basis. He is right: of course there is a tension between national standards and localism. We are five years into this Government and it is about time some of those tensions were resolved. It is causing real issues at local level.
The BRE, which is expert in sustainability, has stated that:
“Over 75% of the sustainability requirements currently covered by the Code will no longer be covered by any UK standards or regulations”.
Is that factually correct? I would like to know if that is the case. What might that 75% include? How will that be compensated for in the new arrangements? In short, I would need to be convinced that whatever is coming forward will have the universal nature of the code for sustainable homes, that it will be as accessible and as easily applied, and that it will have the impact that the code can have in terms of efficiencies. What is going to happen to energy bills and to energy efficiencies within the home? I do not think that the House would want to proceed with this clause unless we could be certain that we knew the answers to those questions, and that we could say to people outside this House that the energy situation and their energy bills would get better as a result of these changes.
