Amendment of the law

My hon. Friend is making a powerful point on park homes. Through her, may I make the point to those on the Treasury Bench that many people on low incomes live in park homes for most of the year? They may be paying rather a high price for the fuel that heats those homes, which are often poorly insulated. When I go into many of my constituents' park homes, I find them there with many plugged-in electric heaters, and that costs them a fortune. They often have historical industrial conditions such as emphysema. It is important that the Government take seriously the insulation and the standard of those homes to ensure that those people, who, as I say, are often on low incomes, do not find that most of their money goes on keeping themselves warm.
