Electricity and gas prices vary from region to region, and sometimes from home to home - depending on your meter type. Your energy bill is made up of a range of charges which you can learn more about below.

Annual Price Plan review

To make sure you're on the most cost effective price plan, we check your energy usage every 12 months (as long as you're not on a fixed term plan). If we've got a better price plan for your needs, we'll automatically change it for you. It's all part of our commitment to great service. 

Think your usage might increase or decrease due to a change of appliances, or a change in who's living at home? Get in touch and we can talk to you about pricing and plan options.

What's in an electricity bill?

// Energy 46%

The cost of generating and providing the electricity you use. Mercury works out this part of your bill.

// Transmission 10%

The cost of moving electricity over Transpower's National Grid between power stations and local lines. Your lines company tells us the cost.

// GST 15%

Goods and services tax (15%) Just like buying groceries, GST applies to all parts of your bill.

// Distribution 25%

The cost of moving electricity over from your local lines company to your property.

// Metering 5%

The cost from companies that own, maintain and read electricity meters.

// Other less than 1%

This covers the Electricity Authority Levy. The Electricity Authority is responsible for the operation of the electricity market.
