This country has a long history of poorly insulated buildings, which, as the hon. Gentleman knows, goes back many generations. The Government are making a real effort to ensure that much more attention is paid to insulation. We have already insulated 5 million buildings in the domestic sector as a consequence of our carbon emissions reduction target provisions and the obligations on energy companies. Our current programme will lead to the insulation of a further 6 million buildings, and, as I said earlier, we have introduced energy performance certificates. We have the green homes service, run by the Energy Saving Trust, and we have the Act On CO2 helpline.

There are many, many strategies in place, and we are making improvements. People are saving money as a result of our policies, and they are lowering their carbon emissions. However, we accept that there is much more to be done. We recently engaged in a major consultation on a heat and energy saving strategy, which will bring about improvements in millions of houses over the next few years.
