Metering apparatus (1) comprises means (8) for metering the supply of a service to a consumer, an indicator (2) for indicating the meter reading, and valve means (11) for selectively enabling and disabling the supply of the service to the consumer. The apparatus (1) includes input means (4) for input by the consumer of a code comprising a coded meter reading, and control means (9) for decoding the meter reading from an input code. The control means (9) controls operation of the valve means (11) in dependence on whether the decoded meter reading is within a predetermined tolerance of the current meter reading of the apparatus. For example, reconnection, disconnection or maintenance of the supply may be dependent on the decoded meter reading being within said predetermined tolerance.
