Diolch, Llywydd. I’m delighted to introduce this debate, and could I thank colleagues—Jeremy Miles, Simon Thomas, Lee Waters—who’ve also put their name to this debate today, and others who might be speaking? But could I also thank those hidden servants of the house in the research unit as well, because, in preparation for this debate, anything that I say that sounds good will be because of them? Anything lousy will be me.

So, I want to first of all explain why we’re speaking to this motion today, which is seeking to get the real formal, hard-headed recognition of energy efficiency, particularly domestic energy efficiency, as national infrastructure. But also, we say within this motion that the scale needs to be dramatically scaled up. That doesn’t simply rely on Government. We look at innovative ways of doing that. So, for example, within the motion, we talk about the use of pension schemes and other innovative financial models to scale-up that dramatic scale-up in investment that we want to see. But, most importantly, there’s the inclusion, as national infrastructure, and in Wales’s case in particular, within the national infrastructure commission for Wales remit—. That is emerging. It’s there in the background and going along. We want to see this come forward and be written down in black and white—that domestic energy efficiency is part of their remit. Why? Well, I’m going to begin by talking about the 2015 report by Frontier Economics, ‘Energy Efficiency: An infrastructure priority’. It made the case for classifying domestic energy efficiency as infrastructure. They noted that traditionally the term ‘infrastructure’ brings to mind projects like roads and rail and energy supply initiatives, but the report explored a wide range of definitions of infrastructure, covering two aspects.
