Who delivers your electricity, and what it costs
Running cost is the tariff multiplied by how hard the system works. The tariff is set by the distribution network for your postcode, not by you, and it is the half of the equation most people never see.
| Network | Flat rate | Suburbs we cover |
|---|---|---|
| Western Power | 33.2621c/kWh | 123 |
| Horizon Power | 33.2621c/kWh | 1 |
Horizon Power customers pay 33.2621c where Western Power customers pay 33.2621c. Same power, same appliance, different bill — and nothing you can do about it except know which side of the line you are on. Our running cost research shows how far this goes nationally.

Rebates in Western Australia
Western Australia has no general household air conditioning rebate. There is no equivalent here of Victorian Energy Upgrades or the NSW Energy Savings Scheme, so a quote advertising a large "government discount" deserves a direct question about which scheme it comes from. Our rebate guide covers every state, including the ones where the honest answer is nothing.
