No, because it is unlikely that your meter readings actually are incorrect.

[Data](https://help.ioenergy.com.au/metering?hsLang=en#data) # Could my meter readings be incorrect? ## It's not impossible but it's highly unlikely. You should troubleshoot all of your appliances before raising a concern. It's not impossible but it's highly unlikely. Yes, it is theoretically possible, but meters are built to a regulated standard so most likely they are correct, even if you doubt them. In our experience when there are doubts about meter accuracy the meter is usually correct and the consumer is incorrect. There is probably a 'phantom load' that you have forgotten about, so make sure to troubleshoot in detail. This is even the case when you are receiving different data from a third-party energy monitoring device (e.g. a Powerpal or a SolarEdge), because consumer-grade devices are more prone to error than industry-grade electrical meters. This is because industry-grade meters that are used for billing purposes are strictly regulated, highly sophisticated, and constantly monitored devices. Consumer-grade meters, on the other hand, are not. ### What should I do if I suspect my meter reads may be wrong? If you suspect that your meter readings may be incorrect, take a two-step approach. 1. Troubleshoot the issue in detail and collect objective evidence 2. If you are convinced, ask us to request a meter investigation Step 2 takes time to organise and may result in a fee that we pass onto you through your bill, so Step 1 is critical for a quick and timely resolution. ### How can I self-investigate my meter readings? When you self-investigate your meter, do the following in order: - confirm your NMI (National Meter Identifier) and meter number(s), - list every electrical device on your site, and - troubleshoot the energy use of every electrical appliance. First, confirm your NMI (National Meter Identifier) and meter number(s). The issue may not be that the meter is faulty, but that your customer account is linked to the meter. You can determine this by cross-checking the NMI and/or the meter number(s) on your electrical bill with the equipment in your meter box. Next, list every electrical device on your site. Simply thinking through all of the devices that operate on-site can help clarify where energy is being used, as you may have forgotten something like a hot water system that operates 'out of sight, out of mind.' Next, troubleshoot the energy use of every electrical device. You can do this in a variety of ways depending on what is convenient to you. One option is to turn off every single electrical device at your property for 1-2 days (e.g. over the weekend) and review your daily meter data after. If the data shows energy being used you either failed to turn everything off, your meter is not measuring what you thought, or it is faulty. Another option is to measure the energy being used by your devices by placing smart power plugs between your electrical sockets and your electrical devices. Like other third-party devices these are not as accurate as industry-grade meters, but if you progressively move these devices around your property you will get a sense for exactly how much energy your devices are using and this may provide the evidence you need to determine what is the driver of your readings.  - [Sustainability](https://help.ioenergy.com.au/sustainability?hsLang=en) - [Metering](https://help.ioenergy.com.au/metering?hsLang=en#main-content) - [About](https://help.ioenergy.com.au/metering?hsLang=en#about) - [Installation](https://help.ioenergy.com.au/metering?hsLang=en#installation) - [Data](https://help.ioenergy.com.au/metering?hsLang=en#data) - [Billing, Pricing, and Payments](https://help.ioenergy.com.au/billing-pricing-and-payments?hsLang=en#main-content) - [Payments](https://help.ioenergy.com.au/billing-pricing-and-payments?hsLang=en#payments) - [Pricing](https://help.ioenergy.com.au/billing-pricing-and-payments?hsLang=en#pricing) - [Billing](https://help.ioenergy.com.au/billing-pricing-and-payments?hsLang=en#billing) - [Account management](https://help.ioenergy.com.au/account-management?hsLang=en#main-content) - [Joining](https://help.ioenergy.com.au/account-management?hsLang=en#joining) - [Moving and Disconnecting](https://help.ioenergy.com.au/account-management?hsLang=en#moving-and-disconnecting) - [Energy optimisation](https://help.ioenergy.com.au/energy-optimisation?hsLang=en#main-content) - [Purchasing and Installing Smart Devices](https://help.ioenergy.com.au/energy-optimisation?hsLang=en#purchasing-and-installing-smart-devices) - [Export optimisation](https://help.ioenergy.com.au/energy-optimisation?hsLang=en#export-optimisation) - [Import Optimisation](https://help.ioenergy.com.au/energy-optimisation?hsLang=en#import-optimisation) - [About iO Energy](https://help.ioenergy.com.au/about-io-energy?hsLang=en#main-content) - [General Questions](https://help.ioenergy.com.au/about-io-energy?hsLang=en#general-questions) - [Other](https://help.ioenergy.com.au/other?hsLang=en#main-content) - [General](https://help.ioenergy.com.au/other?hsLang=en#general) - [Emergencies](https://help.ioenergy.com.au/other?hsLang=en#emergencies) - [Transfers](https://help.ioenergy.com.au/transfers?hsLang=en#main-content) - [Transfers](https://help.ioenergy.com.au/transfers?hsLang=en#transfers) - Quick Links - Products - Business - Residential - Why Choose iO - Support - Hardship - Basic Plan Info Documents - FAQ - Reach Us - hello@ioenergy.com.au - Contact Us # iO Energy ioenergy.com.au Help Center Copyright © 2025 iO Energy
