How to Read Your Electricity Bill
Learning how to read your electricity bill comes down to a handful of numbers and identifiers that appear on every Australian electricity bill, regardless of retailer. GloBird Energy is an independently owned Australian electricity and gas retailer, and this guide walks through each part of a standard bill – your meter identifier, the charges themselves, and what to check if something looks off.
The Key Identifiers on Your Bill
Every electricity bill carries a National Meter Identifier (NMI) – a unique 10 or 11-digit number tied to your specific connection, used whenever you switch retailers, get solar installed, or need to access your meter data. You’ll also find your account number, supply address, and the bill’s issue date, usually near the top of the first page.
Your bill will also state whether it’s based on an actual meter reading or an estimated one. An estimated bill is a projection based on your historical usage, typically used when a meter reader couldn’t access the property that cycle. If you keep receiving estimated bills, it’s worth asking your retailer about a smart meter or submitting your own reading, since estimates can drift from your real usage over several cycles.
The Charges Breakdown
Every bill splits your total charge into a daily supply charge – the fixed cost of staying connected to the grid – and a usage charge, based on your actual consumption in kilowatt-hours (kWh). If your property has a dedicated circuit for high-draw appliances like an electric hot water system or pool pump, this may appear separately as a controlled load (sometimes shown as CL1 or CL2), typically charged at a lower rate during a set off-peak window since it can be switched on and off independently of general household demand.
If you have solar panels, a feed-in tariff line shows the credit for energy your system exported to the grid – note that residential solar feed-in tariffs don’t include GST, unlike the rest of the bill. Any eligible government concessions or rebates, and any retailer discounts you qualify for, will also appear as separate line items rather than being folded into the headline rate.
The “Better Offer” Disclosure
Retailers are required to show customers whether a better-value plan is available to them based on their own usage history – this appears as a specific section on the bill, separate from the charges themselves. It’s worth reading this section on your own bill directly rather than assuming your current plan is still the best one available, since retailers periodically update their offers and older plans can fall behind newer ones over time.
Meter Numbers and Consumption Details
Your NMI is specific to electricity – gas bills use a different identifier, the Meter Identification Reference Number (MIRN), for the same purpose. Most bills also show your average daily usage for the billing period, sometimes alongside a comparison to similar households in your area, which can help you spot whether a spike in usage lines up with a specific change (a new appliance, a season change, more people at home) or looks like it might be a billing or meter issue instead.
What to Do If Something Looks Wrong
If your bill is estimated and looks noticeably higher or lower than expected, you can usually submit your own meter reading directly to your retailer to have the bill corrected against actual usage. For anything else that doesn’t add up – an unexpected charge, a discount that seems to have dropped off, or a reading that doesn’t match what you can see on the meter – contact your retailer directly.

How to Read Your Electricity Bill: Frequently Asked Questions
What is an NMI and where do I find it?
Your National Meter Identifier is a 10 or 11-digit number unique to your electricity connection, usually shown near your account details at the top of the bill. You’ll need it if you switch retailers.
Why was my bill estimated instead of based on an actual read?
Bills are usually estimated when a meter reader couldn’t access the property during that billing cycle. You can submit your own reading, or ask about a smart meter upgrade, to reduce how often this happens.
What is a controlled load charge?
A controlled load is a separately metered circuit for specific high-draw appliances, such as electric hot water systems or pool pumps, usually billed at a lower rate during an off-peak window since it can be switched independently of general household demand.
How do I know if I’m on the best available plan?
Check the “better offer” disclosure section required on your bill, which compares your current plan against other options based on your own usage – or use a free comparison tool for an independent check.
