Your tariff (also known as variable charge) depends on how your electricity meter is set up.
Here are some common types of meter setup:

• Anytime – a 24-hour continuous supply of electricity.
• Economy – gives at least 19 hours of power a day for hot water. It can be ‘controlled’ by your lines network company and may be turned off during peak times.
• All day economy – a combination of Anytime and Economy through a single meter. This gives a continuous supply of power to all appliances except hot water.
• Night – this is used only at night for 7-9 hours. It’s usually connected to appliances that are only used at night like underfloor heating or night store heaters.
• Day/Night – a 24-hour continuous supply of electricity. It divides your tariff into two time periods, day and night.
• Smart tariff – these are based on ‘time-of-day’ plans. For example, our Good Nights, Good Weekends and Good Charge plans.

If you have an older non-smart meter tariff, you will be able to see all the meter types you are billed for on your meter board. 

If you have a smart meter, the meter types are contained within one unit and show as ‘registers.’

You can see your meter setup on the second page of your electricity bill under the detailed breakdown of charges.
