May I reiterate the importance of improving the energy efficiency of the existing housing stock and remind my right hon. Friend that on top of the problems of older houses and private landlords there is also the issue of housing of non-traditional construction, much of which is in the control of local authorities, and almost all of which is lived in by people on very low incomes? Those houses cannot be easily made energy efficient, but they must not be left out.
