Minister, those figures you quoted earlier—129,000 people being helped, 50,000 homes—is good news across Wales. But, of course, those programmes were underpinned very often by a guarantee offered from the Cavity Insulation Guarantee Agency. Now, when those developers have gone wrong—either we've had a rogue developer, or we've had faulty materials, and, as a consequence, the homes have become damp and problematic—it is important, therefore, they're able to rely upon that guarantee to ensure those errors are rectified. I still have constituents who are raising concerns that they are having difficulty in getting those guarantees assured and delivered. Will you once again look at this programme to ensure that the guarantees are there for people, so that, when things do go wrong, they're able to have that and not have to spend thousands of pounds in rectifying errors, which they shouldn't have had to do?
