I would respond with some surprise, Mark, because all authorities have met the standard for the Welsh housing quality, which is EPC D, apart from what are called 'acceptable fails'. So, if you have details of why he's concerned that the stock isn't up to standard, I'd certainly like to see it. His own council has submitted returns to us saying that they are satisfied that they have rolled out the Welsh housing quality standard, so, I'd genuinely like to see what's being referred to there. So, I'd like to understand that. 

We are in the process of discussing with registered social landlords and stock holding councils right across Wales the next iteration of the Welsh housing quality standard and to what level we expect homes to be retrofitted yet again. So, we're going to bring them up from the EPC D that we currently have, which I'll remind you we were told we could never possibly do in the time but we have actually managed to do it. We're in advanced discussions about where the next stage will be—EPC B, A—what can we bring homes up to and for what level of money, and over what time period. So, it will be very important to understand any difficulties in the previous iteration, and I would really very much like to see the evidence that has been put in front of you, so that we can have a look at it. But, I assure you that our gold standard is to make sure that all homes capable of being brought to the standard of the Welsh housing quality standard are brought to that standard, and there's a rigorous investigation of why any home couldn't be brought to that standard, and the acceptable fails are minimised and we understand the reason for them, rather than not doing anything to the properties that we think couldn't come up to the full standard. So, that's the situation as it is at the moment.
