I know that the hon. Gentleman takes a particular interest in this subject, and what he has said makes a good deal of sense. We have been working closely with key industry stakeholders in the run-up to a public consultation scheduled for April this year. It is vital for us to try to increase the skills and capability of the industry in order to improve energy efficiency. I agree with the hon. Gentleman that the present circumstances present a huge opportunity for Britain and the British economy to ensure that homes are energy-efficient, and also to help to stimulate the construction industry.
