Climate Change and Sustainable Energy Bill

I believe in the market mechanism. One of the ironies about the figures on the proportion of household income spent on energy to which my right hon. Friend drew our attention is that the proportion is declining in richer households while it is rising for poorer households; for example, people living in park homes in my constituency who have high council tax bills and cannot install insulation. As the Minister knows, it is not easy to heat or insulate park homes efficiently. Such people have high fuel bills plus high council taxes. I should like something to be done to help them, but I do not think that adding to their burdens by pushing up the cost of electricity by requiring suppliers to buy microgenerated electricity, which is not economic to them, will help to lower fuel prices.
