A smart tariff charges different electricity rates depending on the time of day electricity is used.
Most smart tariffs include:

Homes with flexible electricity usage can reduce costs significantly with the right tariff.

They are often suitable for:
- electric vehicle charging
- heat pumps
- solar battery charging
- night-time appliance usage

What affects smart electricity costs?
- peak electricity rates
- off-peak electricity rates
- standing charges
- usage timing
- overall annual electricity consumption
The cheapest smart tariff depends on the balance between these factors.
Are smart tariffs cheaper?
Smart tariffs can reduce electricity costs if usage is shifted to cheaper periods.

Comparing annual electricity cost is more accurate than comparing unit rates alone.
