What is Smart meter requirement?

A smart meter is a meter that sends your energy usage readings to your supplier without anyone reading the dial, which usually makes billing simpler and can support time-of-use pricing. Some tariffs depend on that data and will not run without one. Ecotricity states no smart meter is required, and Elli also says no. 100Green, Badenova and EDF each state that a smart meter is required. If you rent, or your property has a traditional meter, check the requirement first, since a supplier that needs one may not be able to start your supply straight away.
