Certainly, Minister. We went to ADSSC because they're embedded within social care. We work well with them. We work very closely with Sally Ann Jenkins, who's the director of social services in Newport but also the lead for children for ADSSC. We asked them to assess the costs and savings, and the benefits and disbenefits, over that 10-year period from 2025 to 2035, using the figures from 2022-23. We asked them to look at it in terms of the impact on providers and the third sector, but also knock-on impacts on social care and on adult care. We asked them to look at two options. The first was a 'do nothing, business as usual' option, the second was to look at the proposed legislation to eliminate profit from care.
We worked very closely with them. We've had a number of meetings, because obviously we have had checkpoints where we've been refining, we've been challenging between ourselves the assumptions, the data. We've tried to have thought-provoking debates as part of that, looking at the cost for the Welsh Government, for CIW and for others. We've asked them to review all of the published data out there. It hasn't always been easy around some of the commercially sensitive data that private providers have. So, when we say accurate, we haven't had access to all full information, but I think we have to accept that as part of the work that we're doing.
I think we've got a model that's a logic model based on a systemic view of the costs and the benefits of what we're doing here, and that's quite visual. You'll have seen that with the various options, a, b and c, depending on conversion rates of 50, 25 and 10 [correction: 50, 25 and 0]. We've also asked them to work very closely with 4Cs to look at market oversight reports and to try and triangulate some of that information.
I think, yes, there are some degrees of uncertainty over some of the numbers, because we've had to look at a variety of options. As I've previously said, we've got issues around the number of children in care, we've got issues about the numbers that may convert. So, we've had to work on a range of options there and model those scenarios. I think our commitment has been to continue that work. Particularly now that we've laid the Bill, we can talk to providers about that intention and obviously work with local authorities.
Finally, we're aware that local authorities are in different places. We know that, for example, Carmarthenshire can probably quite quickly cross the line, whereas in Cardiff, with over 1,000 children in care, that is going to be much more of a difficult challenge. There is a variety of providers, but we've also got a variety of different situations that our local authorities are in. We've got as much certainty as we can here at the moment, but obviously we want to refine this as we go forward.
