As Peter said, and as has been said before, the policy to eradicate fuel poverty by 2018 is looking unlikely to be met; certainly the interim targets are. At the moment, about 4,000 people are employed to go into houses and implement the energy-efficiency measures of improving the windows, insulating the walls and the roofs, changing the light bulbs to more energy-efficient ones, and carrying out other such policies. But that's nowhere near enough, given the age of the U.K. housing stock, and the very low rate of building at the moment. We replace about 1% of the U.K. housing stock a year, so it will take them probably longer than 100 years to replace all of the stock. That's far too long in order to meet a 2018 target, given the very low thermal efficiency of much of the older stock.
There are new building regulations that should make the new stock much more efficient, but these still have not all entirely come into force. So the policies, to a certain extent, are effective in dealing with the problems of the housing, although nowhere near enough is being done. There are at least a million dwellings at the moment that are not really fit for habitation in some way or another. But also there is not enough for those whose income is so low that, even if they have efficient housing, they can't afford to meet the fuel needs.
