Yes. I'm very tempted to just say 'yes' and sit down. [Laughter.]

Absolutely, we've already done something in Wales that has not been done in the rest of the UK, and that is, through the Welsh housing quality standard, we've brought all our social housing up to energy performance certificate D, which is a long way up from where it was before. We were repeatedly told that that wouldn't be possible when we started on that journey, so I'm delighted to say that, with one exception, which we've accepted for COVID reasons, everyone else has done it, and that one exception will have finished that process by the end of this year now.

So, we're in discussion with our councils and social landlords already about what the Welsh housing quality standard 2 will look like, and what will be expected, whether we'll be asking them to bring housing up to EPC B or A, what we will do with the housing that can't be brought up to that standard and what other measures can be brought to bear. We're also learning the lessons from the Welsh housing quality standard 1, because for the vast majority of homes it was very successful, but for some homes it was not successful and it led to some problems with condensation and damp, which I know Members will be familiar with, and I certainly am in my own constituency. So, we've learned that lesson. We've put the optimised retrofit programme in place to figure out what each house in Wales actually needs, so what combination of insulation type, tech, roof type and so on is required to get properties up to the highest EPC rating that they can achieve.

We also haven't yet announced the successor to the Arbed scheme. The Arbed scheme was very good for many people in fuel poverty in Wales, because it replaced very inefficient boilers with much more efficient ones, but they were still gas and they were still contributing to carbon, so we don't want to do that, but it's not sufficient to just say, 'We'll give you an air source heat pump,' because, as I've said many times in this Chamber, you may as well be heating the field behind your house for some houses. So, we need that combination.

As we did with the Welsh housing quality standard, we will overskill the workforce through the social housing projects, so that we can then offer grants to people in the private sector, knowing what will suit their type of house and knowing that we will get good value for money. I think I'm about to be asked a question on the order paper by another Member of the Plaid group about some of the issues we've had, and what we are trying to do is learn the lessons there, so that we aren't fitting the wrong type of tech solution to the wrong kind of property. So, these things are always very successful for the vast majority of people who have them, but then we have had problems with some housing, so we're trying to learn those lessons and to make sure that we get the right solution in the right place. So, we'll be shortly announcing the new Welsh housing quality standard to bring that up.

There's a piece of work to do in the private rented sector to make sure that we have the right incentives, so people don't just come out of the sector but bring their houses up to quality, which I've mentioned many times, and there are a range of other things that we can do for owner-occupiers, including using carrots and sticks in the local tax system, which we'll want to bring to the floor of the Senedd.
