I'll talk about some of these things, but I wanted to return to the original question that we were set. I come back to what Toby said earlier—I think it's really important to recognise that procyclical nature of the private developer market in terms of its relationship with social housing and affordable housing opportunities. There was a period when it was fair to say that, in recessions or economic turn-downs, there was a counter-cyclical benefit from social housing. I think one of the things that has been apparent in the last five, six years, but particularly in the last two or three years, is the failure of that counter-cyclical level of things, and maybe that reflects the cumulative effects of the things that Toby was talking about, because of the dominance of the private sector model.
In that context, actually, I'd just refer to something that we wrote about in our written evidence. It is extraordinary, as to the Home Builders Federation's point that there's a lot of section 106 money unspent, that there's literally money on the table that isn't being used. I don't quite understand the whys and wherefores of how that's happened, and I guess each case is different at some level, but it's a remarkable thing in the era that we all live in of various forms of fiscal austerity operating from the UK to the devolved nations that that should be the case in England and in Wales. So, I'd point that out.
But the point I really was going to make before we had that very interesting digression is about the kind of choices that people at housing associations have about whether they get involved in development. Clearly, as in Scotland, we're very reliant on housing associations as the prime developer of social housing, but they're independent organisations. It may be their mission to deliver more social housing, but they face real challenges because they have other commitments, some of which come from the UK and the Welsh Governments, such as their commitments to climate change and suchlike, such as their asset management requirements to improve the quality of the existing stock, and we must never forget the importance of improving existing stock, as well as trying to build new homes. So, their rental surpluses, such as they are, or their planned rental surpluses can only go so far, and they have to make difficult choices. They will, on occasion, choose not to build new homes in that context, and that's not in any way an unreasonable position to hold. It depends on the specific circumstances of the association, the local context, the land that's available, how much they have to pay for the land—because another issue as a consequence of the private dominance of the development sector is that RSLs are trying to compete against private developers for land, and that simply doesn't work. I know that's something we're going to come on to later on.
The other thing to say, finally, is that we're all also buffeted by UK Government decisions that impact on how the housing systems function, the local housing allowance being a good example, or the levels of universal credit, et cetera, but also the UK system of mortgage regulation as it has been since 2008, which, of course, greatly reduces the effective demand for home ownership. It means people have to go elsewhere, which puts pressure on the private rented sector, which, in turn, puts pressure on social housing as well. So, these things are always complex and multiple things go on, because that's the nature of the housing system. But I do think RSLs face difficult choices, so it's great that, by ending the right to buy in Wales, you've actually created an environment where councils can start to build again and will, undoubtedly, do a good job.
