There are two types of plan available to Kiwi households: Standard User or Low User. Under either you'll be billed both a daily rate, and a usage rate per kWh (kilowatt-hour) unit of electricity consumed. It’s entirely up to you whether you sign onto a Standard or a Low User plan, but depending on your circumstances you may be much better off on one rather than the other. Here’s why...

The Standard User plan has a higher daily charge, but a lower charge per kWh used, so is ideal if your electricity usage is relatively high. Households north of Christchurch are better off on a Standard plan if using more than 8,000 kWh each year, and for Christchurch and further south if using more than 9,000 kWh each year. Conversely, if your annual usage is lower than that number, a Low User plan is more advantageous. A Low User plan is generally suited to people using less electricity than average (hence the name!). It’s designed so that the fixed rate is no more than 30 cents a day* but the unit rate is higher, which means that if you don’t use much electricity you'll pay less than you would on a Standard User plan.In general, you should pick a Low User plan if your household has one or two people living in a well-insulated, energy-efficient home, often with gas for heating or hot water. Very roughly, these households will spend much less than $200 monthly averaged across the year – although the exact level will vary in different parts of the country. Standard rate plans will suit larger households, where people are home a lot, and electricity is used for hot water and heating.

Note that while for most of the country the tipping point between the two plans is 8,000 kWh annually, the average household is better off on a Low User plan.You can switch between Low and Standard user plans once a year.*not including GST, and after any bundle discount

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-hour).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.

Please let us know if you or a family member are medically dependent on power, and whether loss of electricity may result in loss of life or serious harm. Medical dependence on electricity could be for use of medical or other electrical equipment needed to support a treatment regime.

If any member of your household is medically dependent, then you should advise us immediately, if you have not done so already.We will request evidence of medical dependency – it’s likely that the GP has already provided this in a letter.
