I'm not going to repeat anything said by either Rhys or Peter, but the tragedy of Grenfell Tower saw 72 people lose their lives. It was reported earlier this year that surveys on high-rise buildings across the UK, following the fire, have shown that combustible cladding and fire safety defects are causing issues in other high-rise buildings—lots of other high-rise buildings. The Welsh Government estimated a third of high-rise buildings across the country may need remediation work, with defects ranging from minor to significant. There are currently 148 high-rise residential buildings across Wales.

The public inquiry that followed the incident at Grenfell Tower has revealed that one of the main reasons the fire spread was the type of cladding that was used on the exterior of the building. In my constituency, I'm told that residents of South Quay in SA1 will see their service charges increase more than £450,000 between them to pay for cladding and insurance work. However, the cost to rectify all issues across the site in the years to come has been estimated at over £3 million.

I agree with what the Minister has previously said, that developers who have made millions and millions of pounds out of these buildings ought to pay. Unfortunately, some of them were built by the defunct Carillion, others may have been built by other companies or single-purpose vehicles that now no longer exist.

In two places in my constituency, both the Copper Quarter and SA1 developments, there is a serious concern regarding the issue of cladding. People owning properties are concerned about their safety and the catastrophic drop in value of their properties, many of which have been bought on a mortgage and are becoming very difficult, if not impossible, to sell. To many of the people affected, the cladding issue is the biggest issue in their lives.

It's not purely a Welsh issue, and Members will be aware of the complex challenges facing multi-occupied buildings across the United Kingdom. This is a problem throughout the whole of Great Britain, and the funding will have to come from the Westminster Government. For too long, residents of affected buildings have been denied the right of confidence in the safety of their homes and the ability to move on, to sell their homes, move somewhere else; something all the rest of us take for granted, that if we've got a house or building, we sell it, we can then buy something; we can either trade up or trade down. These people can't; they are stuck, and they are really upset, and I can understand why they're upset. And people talk about mental health a lot in here. Can you think of anything to affect your mental health worse than having a position where you've got a huge debt, which you are paying, but you can do nothing with? You can't solve the problem of the debt, you've got substantial negative equity and you cannot see a way out of it, but you've got additional bills likely to come. I've had grown men and women crying to me on the telephone regarding the effect this is having on them. This is a real issue affecting real people. Something has to be done. We need funding from Westminster and a charge on building companies to deal with this serious problem, and we just have to deal with it, otherwise a lot of people are going to be in a very bad state.
