Yes. So, Alicja has set out, the right to adequate housing is about providing a vision and a legal framework that reflects our moral sense that access to a home is a human right. And I suppose the imperative to act, really, comes from the fact that the status quo is not tolerable. Housing inequalities in Wales are blighting people's lives, they are impacting people's life chances. We know that housing is a really key determinant in terms of people's health, well-being and their life chances and even the length of their life in terms of access to housing.
So, we're in a deepening housing emergency in Wales, so the imperative to act is clearly there. Even prior to the cost-of-living crisis, we undertook a YouGov poll at Shelter Cymru and that identified that one in three people in Wales had issues in terms of their housing—facing significant issues, whether that was around the safety of their housing, the affordability of their housing, the fear of loss of their home, and facing discrimination in accessing a home. And that has an impact as well on people's well-being. Our casework speaks of people who are living in very poor and unsafe conditions. We support over 10,000 households each year across Wales. It also speaks of people who are in bed and breakfast, trying to live their lives while sofa surfing and people who are sleeping in cars and people who are sleeping on pavements. So, the imperative to act is very clearly demonstrated in terms of the people who seek our help.
The most extreme denial of a right to adequate housing is homelessness. So, there's a continuum, and rough-sleeping is at the furthest extreme, really, of the absence of realisation of that right. The latest Welsh Government figures showed 100-plus people rough-sleeping and over 9,000 people in temporary accommodation. And within that 9,000, we know that 2,700, approximately, of those people were children. So, the impact on people's lives of this continuing bottleneck that is building up in temporary accommodation at the moment, with more people becoming homeless than can be moved on to settled accommodation, is at a significant scale. And our casework would suggest that those figures underestimate the true extent of homelessness, and that not everybody who is in need of help is able to access the help that they require.
Beyond that end of the continuum in terms of homelessness, what we also know is that we've got 89,000 people on housing waiting lists, waiting for social housing in Wales, and that really reflects the legacy of long-term underinvestment in social housing and a lack of social housing stock. And that rebalancing of tenure from social housing to having a greater proportion of people now accommodated in the private rented sector, where rents are typically twice as high as they are in the social housing sector—we know that has contributed to increased housing inequalities.
So then, looking particularly in the pandemic period onwards at really significant rises in the levels of rents in Wales, outpaced, really, only by the levels of rent rise in London, what we know now about what's happening to both rents and mortgage rates outpacing pay and outpacing benefit rises—what that means is that there are very, very few options for people. So, that stress of homelessness, the impact of overcrowding and people who are having to put their lives on hold, whether that's their family life, their working life, the impact on their education et cetera, that impact is spreading because of the lack of affordable housing options for people in Wales at the moment.
So, what we know is that all of these challenges play out in very different ways in different parts of Wales and in different communities. But what they have in common is that they're symptoms of a wider housing emergency, and there simply aren't enough homes for people that are of decent quality that are suitable for their needs and which people can afford.
So, beyond that, there are issues around quality as well as access to housing. So, there have been various high-profile tragedies that you'll be aware of in relation to Grenfell, in relation to the case of Awaab Ishak, for example. And they highlight as well that imperative to act in relation to poor housing. The most recent TPAS tenant pulse survey done here in Wales showed that damp and mould are huge issues for social and private rented sector tenants in Wales. Only 40 per cent of tenants who responded to that survey said their home was free from damp and mould, and our case load is showing a rising case load of damp and disrepair cases at present.
The Welsh housing conditions survey, last done in 2017-18, showed that 18 per cent of the stock had category 1 housing health and safety rating system hazards. That's really significant. That's defined as poor housing in a report that was jointly produced by the BRE Trust, Welsh Government and Public Health Wales. And that same report identified that investing in addressing those issues of poor housing would result in savings to the NHS of £95 million annually, and therefore would pay for itself within six years.
So, in summary, in terms of why we need a right to adequate housing, it's because we can't afford to leave access to such a fundamental human right as housing to people's ability to compete for scarce resources. Legislating for a right to adequate housing would develop the pace that we need and it would overturn the long legacy that we've had of underinvestment that has left people in the position that they find themselves now, unable to afford a good home. And it will develop that long term, system-wide driver and develop and deliver a road map for how we get from where we are now, which is a position where I think it would be hard to find anybody who wouldn't agree that the system is broken, to where we all aspire to be, which is in a Wales where everybody has access to a good home. This is about providing that road map; it's about driving the delivery of that road map.
So, it's not just the right thing to do morally as well—that moral case is strong and is widely supported—the cost-benefit analysis that we commissioned, an independent cost-benefit analysis, which I understand you'll hear more about today, shows that it's also good for the public purse, and it helps to deliver on a wide range of priorities that we have here in Wales that really go to the heart of who we are as a nation in terms of social justice, in terms of equalities. There is no social justice without housing justice. So, it's very fundamental, I think, to who we are and what we seek to achieve, but it provides us with the road map and the driver and the long-term thinking, critically, that we need to get us there.
