Yes, the Member raises a very important point, and there are clearly some examples where people who've benefited from both UK and Welsh Government schemes designed to improve energy efficiency in their home—they've experienced problems, particularly with damp, and other associated problems. I know it is a matter of concern for a lot of Members, right across the Chamber—just yesterday, I met with our colleague Dawn Bowden, who's got concerns in her constituency. We know that, when it's installed and maintained correctly, it can significantly improve people's qualities of life and alleviate poverty in the way we've discussed.
