Well, Llywydd, I understand exactly the point the Member is making about the nature of construction of houses in parts of Wales; it's not confined to the part of Wales that the Member represents. And we have local authorities who have put forward plans to us that allow us to help them to invest in novel and innovative technologies, that, even where the basic construction of a home doesn't lend itself to normal forms of insulation, there are still things that can be done. It is not easy—I do not for a moment suggest that, in the types of houses to which Mabon ap Gwynfor has referred, there are easy solutions in this matter. But we continue to work with the industry and with local authorities, where they are able to come forward with innovative proposals, to try to find solutions for people whose homes, by the nature of their construction, mean that conventional means of insulation simply won't work for them.
