What the Home Energy Score measures
The score weights each part of your home by how much it typically affects energy bills and emissions. Heating carries the most weight because space heating is usually the largest single energy use in homes in colder climates; insulation, water heating and solar come next. Quick, low-cost habits like thermostat settings and standby loads carry less weight but are often free to fix.
How to read your result
- 85–100 (A): a lean, efficient home. Your next lever is generating or storing your own energy.
- 70–84 (B): good, with a few clear upgrades left.
- 55–69 (C): average — meaningful savings available.
- Below 55 (D–E): high potential; the top actions usually pay back fastest.
This is a self-assessment for planning, not an official energy rating such as a US DOE Home Energy Score, a UK EPC or a Canadian EnerGuide evaluation. For a certified assessment, book a professional energy audit — many utilities subsidise them. Our DIY energy audit checklist is a good first step.
Frequently asked questions
Is this an official energy rating?
No. It's a free self-assessment to help you prioritise. Official ratings (DOE Home Energy Score, EPC, EnerGuide) require a qualified assessor.
Why is heating weighted so heavily?
In most homes outside hot climates, space heating is the largest energy use, so it has the biggest effect on bills and emissions.
Do I need to give my email?
No. Your score and action list appear instantly. Email is optional if you want the plan sent to you.
