Metering arrangements between a supplier (1) of services such as electricity, water or gas and a consumer (2), in which the consumer conveys encrypted usage information to the supplier. Equipment (3) generally including a visual display (4) is installed at the consumer premises and may be operated by the consumer on a voluntary basis. Incentives such as rebates are provided for the consumer to provide the information to the supplier. The arrangements may be part of a prepayment system or a more traditional system involving statistical estimation and billing of the supply. |
