I support the principle of waste charges at household level. The main argument for charging at that level rather than including the cost in general taxation is that individual charges can establish a link between a person's behaviour and the amount that he or she pays. They are, or they should be, based on the principle that the user pays. The importance of the approach is that, if properly structured – it is not fully structured yet – the user pays for a service in proportion to the extent that he or she uses it. The more of the service people use, the more they pay, which is the cardinal principle of this approach. This gives users an element of control over how much they pay.
