A method of identifying an event associated with consumption of a utility comprising the steps of: generating a utility consumption profile from utility consumption data, the utility consumption data comprising a plurality of utility consumption values measured at a corresponding plurality of measurement points; wherein generating the utility consumption profile comprises the step of determining a gradient of rate of change of utility consumption between consecutive measurement points; identifying measurement points at which a change in gradient exceeds a predetermined threshold; and storing in the utility consumption profile the utility consumption value at measurement points where the threshold is exceeded; and identifying an event within the utility consumption profile that matches the profile of an event stored in a database of utility consumption profiles.
