Diolch, Dirprwy Lywydd. In this debate, I will set out the urgent need to produce a Government-backed and co-funded scheme to remediate the sub-standard installation of external and some internal wall cladding to homes in Caerau in my constituency under the 2012-13 community energy savings programme/Arbed 1 programme, and to make good the damage done to people's homes and lives.

This is an issue of natural justice. Almost a decade ago, residents were promised warmer and more energy efficient homes with lower bills. In the worst cases, they've ended up with extensive damp and mould and deteriorating conditions, where the defective installations have damaged not just their homes but their lives. So, Minister, I ask the Welsh Government to step in and play a lead role in resolving these issues, because, quite simply, no-one else can now do this.

I am aware that there are other examples of sub-standard insulation in other parts of Wales, and indeed in other parts of the United Kingdom, but my argument, though, to the Minister, and the argument of residents in Caerau, is that the scale of damage in Caerau, the sheer numbers of homes affected and the length of time this has been going on for, mean that a scheme is now urgently needed to resolve these issues. It is long overdue. We need to resolve this now.

At the very outset, let me restate my support for the crucial importance of good-quality retrofitting of older and colder and energy-inefficient homes. In fact, in July, the Future Generations Commissioner for Wales scoped out the huge scale of the challenge, but also the huge benefits if we make the right decisions on retrofit and energy efficiency. She argued that fuel poverty could be eradicated in Wales by 2030, with a £15 billion—in her words—game-changer investment to retrofit homes to reduce energy and heating demand, saving bill payers hundreds of pounds a year in their bills and £8.3 billion a year on bills by 2040, improving and modernising Wales's huge stock of older housing, creating 26,500 jobs every year by 2030 in communities right across Wales, saving the NHS £4.4 billion by 2040, and helping the Welsh Government meet its legal duties of net-zero carbon emissions by 2050.
