How dynamic tariffs work
Dynamic tariffs reflect the real cost of electricity on the market.
When electricity is plentiful - often when there is more renewable energy available - and demand is lower, prices can fall. When demand is higher or market conditions change, prices can rise. The price you pay therefore varies throughout the day.
1. Electricity prices change throughout the day
Example daily price pattern
12am14cLow price
6am12cLow price
12pm18cMedium price
6pm35cHigh price
12am16cLow price
Dynamic tariffs offer opportunities to save by using electricity during lower-priced periods, but prices can also be higher at certain times of day.
2. Why some households benefit more
Dynamic tariffs are not one-size-fits-all.
Households that can move some electricity use to lower-priced periods may achieve greater savings.
EV charging
Laundry
Dishwashing
Water heating
Home batteries
For households with less flexibility, savings may be lower.
