Why homeowners choose Certified Energy
Is this service right for you?
A Home Energy Rating is suited to homeowners who want to understand how their home performs now before making larger decisions about renovations, improvements or future planning.
Living in the home
Useful if some rooms feel too hot or cold, energy bills seem higher than expected, or you want a clearer picture of what may be affecting the home.
Renovating
A rating can help establish what is known about the home before decisions are made about insulation, windows, heating, cooling or other building work.
Buying or selling
Where the home and available information are suitable, a rating can provide a clearer view of its likely energy performance before you buy, sell or plan future improvements.
Where do you start?
It is easy to begin with a product or a single problem: new insulation, better windows, a different heater or lower energy bills. But without understanding the home first, it can be difficult to know what is actually affecting it.
A Home Energy Rating gives you a clearer starting point by reviewing the home as it is now, identifying important features and showing where more information may still be needed.
The home's construction, insulation, windows, orientation, heating and cooling can all influence how it feels and how much energy it may use.
Photos, floor plans, renovation records and construction details help build a clearer picture. Where something is unknown, you will know what still needs to be checked.
The rating helps clarify which parts of the home may need more attention before you commit to renovations, upgrades or further advice.
Understanding your home energy rating
Every existing home is different. Its age, construction, orientation, insulation, windows and systems all help shape how it feels and how much energy it may need.
Send your photos, floor plans or basic home details and we’ll explain what is needed to begin the rating.
REQUEST A HOME ENERGY RATINGWe begin with the plans, photos, construction details and other information available for your existing home.
The review considers the parts of the home that may affect its rating, including its construction, insulation, windows, orientation and relevant energy systems.
Once the required information is available, you’ll receive the rating and a clear explanation of what it says about the home and what may need attention next.
What you'll receive
You’ll understand what information has been reviewed, what the Home Energy Rating says about your existing home and where further attention may be needed.
If you need detailed upgrade planning after the rating, we’ll explain which related service is the most appropriate next step.
Item 01
Your available plans, photos, construction details and other relevant home information are reviewed within the confirmed scope.
Item 02
Once the required information is available, your rating is prepared using the agreed method and scope.
Item 03
You’ll receive a practical explanation of what the result says about the home and which areas may need more attention.
Item 04
You’ll know what is complete, what may still need investigation and whether further advice is needed before planning upgrades.
Industry experience
When you request a Home Energy Rating, you need advice that reflects how existing homes actually differ—not a generic checklist or a product sales process.
Certified Energy’s work across existing-home trials, residential assessments and technical initiatives helps us identify what is known, what still needs checking and what the rating can reliably tell you about your home.
Participation in the national CORE and Scale Stream trials has provided practical experience rating a wide range of existing Australian homes.
Work with industry organisations, including Cotality and Urbanfinity, supports the development and practical delivery of home energy information at a wider scale.
Representation on the National Technical Advisory Committee provides direct insight into the technical development of residential energy rating in Australia.
Your rating is based on the home information and agreed rating scope—not on selling insulation, appliances or other products.

SEND WHAT YOU HAVEFrequently Asked Questions
A Home Energy Rating provides an independent measure of the energy performance of an existing home. The rating considers available information about the home’s construction, insulation, windows, orientation and relevant energy systems to create a clearer picture of how the home performs.
Yes. This service is intended for homes that have already been built and occupied. It may be useful when you want to understand your current home before renovating, planning improvements, buying, selling or deciding what to investigate next.
No. A rating helps you understand the home’s current energy performance. It does not automatically include detailed renovation advice, product selection, cost estimates or a staged upgrade roadmap. If you need more detailed planning after the rating, we can explain which related service is the most appropriate next step.
Start with whatever you already have. This may include floor plans, photographs, renovation records, construction details and information about insulation, windows, heating, cooling and hot water. We will review what is available and explain anything else needed before the rating can proceed.
Not necessarily. Existing plans are helpful, but many homeowners do not have complete documentation. Photos and basic home information may be enough for us to begin reviewing the property and identify what further details are required.
The requirements depend on the home, the information available and the agreed rating method. After reviewing what you send, we will confirm whether further evidence, measurements or an inspection is needed before providing a quotation.
Once the required home information is available and the assessment is complete, you will receive your Home Energy Rating and a clear explanation of the result. We will also explain whether any areas need further investigation or more detailed advice.

Send us any available photos, floor plans or information about your home. We will review what you have, confirm what is still needed and provide a fixed quotation before the rating proceeds.
