Traditional style meters will gradually be phased out and smart meters will become the standard. Government and the industry Regulator, Ofgem, are currently designing the rules and regulations that energy suppliers will have to operate by. This work should be finished by the summer. Ofgem has also set up a Smart Metering Consumer Advisory Group, which will represent the views of customers, to work with them to ensure that customer concerns are captured and understood.
