Electricity charges consist of two components – a Fixed Daily charge (usually quoted in cents per day), and a Variable Usage charge (usually quoted in cents per unit of kWh [kilowatt hours]). Each bill has cost that’s made up of the fixed charge multiplied by the number of days within the billing period, and the variable charge multiplied by the power used over the period (or an estimate of this number). In some cases, you may have more than one variable charge related to different types of supply.

Electricity retailers are charged a levy by the Electricity Authority. Your old bill may show an “EA Levy”. The EA levy is small and we have chosen to include it within our variable charges rather than splitting it out separately.

The other factor that will impact the price is the choice between a Standard plan or a Low User plan. Click here to read more about that.

Please note that your first power invoice may be a little higher than expected. This is due to the initial power usage to be charged being based on an estimate from your previous provider. You should notice this even out by the time you receive your next month’s invoice.

Switching you from your current provider to Slingshot is usually a straight forward process, taking a few days.

It’s possible that you may have a contract with your existing provider that means they can charge you to break the contract, please check this, and be aware of any fees – you don’t want a nasty shock.
