A single rate tariff, also known as a flat rate, doesn’t have any peak and off-peak periods. So, you pay the same rate always regardless of the time of the day you use energy.
A time of use tariff means that you pay different rates during different times of the day – peak when energy costs the most, off-peak when it’s the cheapest and shoulder when it’s a bit less than peak.
It’s sometimes possible to change the tariff you’re on if another one is available at your address. You can do this a maximum of once a year. To talk to someone about changing your tariff type, reach out to an energy expert, they can tell you if another tariff is available for you to switch to.
It may be useful to know your peak, off-peak and shoulder times to understand what might work best for your household.
