How to determine your meter type

Electricity Meter Types

Single-rate meters are used to measure all electricity consumed (there are no separate peak and off-peak tariffs).

Two-rate meters are used to measure electricity consumed for normal light and power (peak tariffs). They are also used to separately measure electricity for electric hot water and/or space heating (off-peak tariffs).

Time-of-use meters are used to measure all electricity consumed at night/weekends (off-peak tariffs) compared to other times (peak tariffs).
