Thank you for that, which is in part encouraging. As you know, the Climate Change, Environment and Rural Affairs Committee has been looking at this whole issue of energy efficiency in housing. Our evidence has suggested that there is a significant number of barriers to delivering transformative change in house building in Wales at the moment. The Home Builders Federation expressed concern that transformative change will result in fewer houses being built, and other organisations, including Caerphilly County Borough Council and the Federation of Master Builders Cymru, echoed concerns that there are already a number of challenges to building the number of affordable homes needed, particularly if housing targets are to be met.

This doesn't sound like the sector are prepared for the challenges ahead, and I think that we've really got to push them because we need much more response from them, and ambition. For instance, we've seen this week that the UK Government has released its ambitious Road to Zero strategy, which includes a proposal for all new homes in suburban England to be fitted with electronic car charging points. This is the type of integrated policy that we need, and I do hope that—. The innovation fund is a great idea, but it needs to lead quickly to mainstreaming those great developments that we know are going to work, such as charging points built into new homes as standard. I do hope that you will challenge the sector, particularly the private house builders, to improve their practice.
