DIY Business Energy Audit

Find out what's contributing to your bill and the steps you can take to reduce your energy costs.

We recommend setting aside 30 minutes to complete this audit.

Have your latest Horizon Power energy bill handy to help complete the audit. You can save your progress along the way and pick up where you left off at a later date. We recommend walking around your business premises as you go to help answer questions along the way. You can access this tool on your mobile, tablet, laptop or desktop device.

Let's begin

1. Let's begin

Tell us a little bit about your business and energy needs
This helps us understand how we can help you today and in the future as new tools, services and information become available.

There's 8 areas that cover the most common appliances and equipment used across small businesses
It's simple Yes/No/Unsure answers to common energy efficient practices. You only need to answer questions related to the appliances or equipment you use. Some questions include additional information; simply select the ? icon to learn more.

At the end we'll provide you a report of recommended energy saving tips
We'll email you a copy of your results so you can start putting in place changes that will help you save.

Tips to help make the most of this energy audit

Every business is unique

This audit asks questions in 8 key energy use areas to help your business identify energy-saving opportunities and begin your energy efficiency journey.

Include key staff in your audit

Your staff can help identify areas of energy waste and how energy is used that you might not be aware of. Having your staff involved in the audit can help with energy efficiency practices that lead to savings opportunities.

Remember to check energy use outside of business hours

Look for hidden energy use through any equipment left on outside of business hours (including overnight or weekends).
