Competition in metering was introduced for larger customers in the electricity market in 1994. Up until that time all metering work had been performed by regional or national monopolies.
As independent Meter Operators entered the market the original metering businesses were separated from their corporate companies. New trading arrangements were introduced to the electricity and gas markets to enable competition in energy supply to develop. The business interests of Meter Operators were found to be different to those of other parties to the trading arrangements.
This resulted in metering companies forming the Association to represent their interests in this evolving market. Since the creation of the Association in 1996 it has grown to encompass all aspects of electricity, gas, smart metering and emerging technologies.
